Description

TECHNICAL FIELD [0001] The present invention relates to a monitoring device for a sulfur oxide removal device for a ship having an automatic purging function,

More particularly, the present invention relates to a monitoring apparatus and method for a sulfur oxide removal apparatus for a ship having an automatic purging function, and more particularly, A gas spraying unit coupled to the filter unit to remove foreign substances adhered to the filter unit by supplying gas to the filter unit when an abnormality of the filter unit is sensed; And a control unit for controlling opening and closing of the valve. The exhaust gas purifying apparatus according to the present invention includes a control unit for controlling the opening and closing of a valve, When analyzing a part after collecting and filtering, particulate matter is excessively splashed in the filter part, and a situation where filter cleaning is necessary is carried out To automatically detect, to the operator on without the need to replace the filter up to the heights, that through the gas injection remove particulate matter, sulfur oxides in the vessel with the auto purge feature removal equipment monitoring device and a method for.

Most modern ships are equipped with engines and boilers for their own power and heating. In order to drive the engine and the boiler, fuel must be burned. The exhaust gas generated in the combustion process includes harmful substances such as SOx, NOx, PM (Particular Matter, Particulate Material) have.

Sulfur oxides and nitrogen oxides can cause respiratory illness by acting on the mucous membranes of the human body, and they are pollutants designated by the International Agency for Research on Cancer (WHO) as a primary carcinogen. When the SOx and NOx are released into the air as they are, they react with water (H ₂ O) in the atmosphere and become sulfuric acid (H ₂ SO ₄ ) and nitric acid (HNO ₃ ), respectively.

PM is a form of small particles compared to gaseous pollutants. PM is emitted into the atmosphere as it is, and it can cause visibility disorder that reduces visibility, or fine particles can enter the human body through the lungs or respiratory tract and cause various diseases . In recent years, fine dust that is a problem in Korea is also caused by PM, which is considered to be the main cause of air pollution.

Therefore, it is necessary to prevent such harmful substances in the exhaust gas. In particular, in the case of a ship, it is known that the output of the engine is large, so that it emits exhaust gas of 130 times that of a passenger car. In order to prevent the emission of a large amount of harmful substances Specific and practical measures are required for the exhaust gas of the ship.

Therefore, the International Maritime Organization (IMO) has set up an Emission Control Area (ECA) to limit the emission of hazardous substances in the sea area. In particular, the SOx Emission Control Area (SECA) has been stricter than the ECA, which regulates other harmful substances such as NOx.

Furthermore, from January 1, 2015, the regulations were further strengthened to limit sulfur content in the fuel to 0.1% (IMO 184 (59)), which causes environmental pollution for all ships passing through the SECA. The SECA was extended to North America from the Baltic and North Sea regions through the amendment of the Convention on Marine Pollution Prevention in August 2011 and will be extended from April 1, Sulfate management is likely to become more important.

In addition to the ECA, legislation to regulate the SOx content in the exhaust gas to 3.5% or less in the waters around the world is scheduled to be implemented by 2020 from 0.5% at the IMO General Assembly held on October 28, 2016, The need for sulfuric acid management is growing even more.

In order to comply with these international regulations, LNG propellant lines, which use low sulfur or low-sulfur natural gas as fuel, are used, but scrubbers that reduce the sulfur oxides of the exhaust gas are used It is also said.

When the post-treatment process is performed using a scrubber, it is economically advantageous to satisfy the above-mentioned regulations even with a low-cost fuel having a relatively high sulfur content and to prevent environmental pollution. As such, the scrubber can meet both economic and environmental requirements, making it highly versatile enough to be used in ships as well as power plants.

In the case of a ship discharging the exhaust gas by performing a post-treatment process using such a scrubber, in order to confirm whether sulfur oxides or the like generated in the engine of the ship are appropriately treated, on the gas outlet of the treated ship exhaust gas is discharged to the atmosphere Monitoring equipment may be installed.

Through these monitoring devices, it is possible to confirm in real time whether pollutants are properly treated in the exhaust gas discharged, to prevent environmental pollution by discharging exhaust gas suitable for international regulation, and to promptly take measures .

FIG. 1 is a diagram of a conventional electrostatic combined wet scrubber system, which is disclosed in Korean Patent Registration No. 10-1453341 (Apr. 22, 2014).

1, the prior art includes an analyzer 93 for analyzing the components of the exhaust gas flowing out of the scrubber 91, a control unit 95 for controlling the cleaning liquid supply unit, an analyzer 93, And a monitoring unit (97) for monitoring the display unit (95).

The analyzer 93 is configured as a sensor and the components of the exhaust gas that can be analyzed by the sensor can be NO, NO2, NOX, SO2, PM, CO, CO2, HCL, The components of the exhaust gas are measured by the analyzer 93 in real time and can be confirmed through the monitoring unit 97.

However, in the above-mentioned conventional technique, no separate means for filtering the exhaust gas flowing out from the scrubber 91 is provided. The exhaust gas flowing out of the scrubber 91 contains a large amount of particulate matter such as soot and dust. When the analysis through the sensor is performed in a state where a large amount of particulate matter is not removed, accurate analysis can be performed none. In the above-mentioned prior art, various components of the exhaust gas can be accurately measured. However, it is obvious that there is a great difficulty in accurately measuring the particulate matter contained in the exhaust gas with the sensing using the light.

In order to prevent such a problem, it is necessary to provide a separate means for filtering the particulate matter before analysis through the analyzer 93 is performed. This is because it is necessary to remove the elements that impede the analysis in the previous step.

However, when the filtering means having a plurality of microvoids formed as a means for filtering the particulate matter is provided in front of the analyzer 93, as the use of such filtering means is repeated, Can be blocked by. If the micropores are clogged, the amount of exhaust gas to be filtered becomes insufficient, and the analysis efficiency is lowered.

In order to solve the problem that the micropores of the filter are clogged by the particulate matter, a method of replacing the filter at regular intervals may be considered. However, it is difficult to replace the filter by replacing the filter with the monitoring device located at the top of the discharge device, and the height of the device for discharging the exhaust gas of the ship is more than 10m. The possibility of an accident such as a worker falling in the process of going up and a filter replacement work is increased. In addition, if such an accident occurs on a vessel that sails on the net, it may take more time to transfer the patient, which can lead to more serious problems because it can not perform effective first aid.

Therefore, in the related art, it is necessary to constitute filtering means in front of the analyzer 93 in order to accurately analyze whether the exhaust gas discharged through the scrubber 91 is discharged appropriately to the exhaust gas emission regulation, and the use of such filtering means It is required to introduce a technique that allows the operator to automatically remove the particulate matter trapped in the gap without having to go up to the spot and work, and the problem that the filtration efficiency is reduced due to clogging of the microvoids of the filtering means In fact there is.

The post-

The cleaning liquid inflow portion 1114 is a portion into which a cleaning liquid to be injected from the inside of the preprocessor 11 flows. 6, the cleaning liquid inlet 1114 is connected to or formed in the first pre-treatment injection unit 112 and the second pre-treatment injection unit 114, respectively, which will be described later.

The cleaning liquid outlet 1115 is connected to the first pre-treatment injection unit 112 and the second pre-treatment unit 112 to remove harmful substances from the exhaust gas flowing into the interior of the preprocessor housing 111 through the exhaust gas inlet 1112. [ 2 is a portion where the cleaning liquid injected by the pre-treatment injection means 114 is discharged. 3 to 5, the cleaning liquid outlet 1114 is formed at the lower end of the pre-processor housing 111. The cleaning liquid outlet 1114 is connected to the first pre-processing injection unit 112 and / The cleaning liquid injected by the second pre-treatment injection means 114 collects the harmful substances in the exhaust gas, moves to the lower end of the pre-processor housing 111, and is discharged to the outside. In order to smoothly discharge the cleaning liquid, it is preferable that the lower end of the pretreatment processor housing 111 is converged toward the cleaning liquid outlet 1114.

The first pretreatment injection means 112 is disposed in the vicinity of the exhaust gas inflow portion 1112 in the interior of the preprocessor housing 111 and injects the cleaning liquid into the exhaust gas flowing through the exhaust gas inflow portion 1112 . As described above, fresh water mixed with seawater and an alkali additive may be used as the washing liquid.

The first pre-treatment injector 112 cools the exhaust gas flowing through the exhaust gas inlet 1112. The exhaust gas flowing through the gas inlet 1112 generally has a temperature of 250 to 350 ° C. The temperature of the exhaust gas flowing through the gas inlet 1112 is reduced to 50 to 50 ° C. by the cleaning liquid injected by the first pre- And the volume is reduced.

In addition, the first pretreatment injection means 112 allows the PM to be primarily collected by the cleaning liquid, among the harmful substances in the exhaust gas. The exhaust gas in contact with the cleaning liquid injected by the first pre-treatment injection means 112 passes through the agitating means 113, the flow path thereof changes from a straight line to a spiral shape, and a second pre-treatment injection means 114 And comes into contact with the cleaning liquid to be sprayed. Accordingly, the cleaning liquid, which is sprayed by the first pre-treatment injection means 112 and collects toxic substances, increases in size, and is moved to the lower portion of the preprocessor housing 111 by gravity.

The first pretreatment injection means 112 injects the cleaning liquid in the form of a fine droplet compared with the second pretreatment injection means 114. [ Specifically, the first pretreatment spraying means 112 may spray the cleaning liquid in the form of droplets having a particle diameter of 100 to 200 mu m. Among the harmful substances of the exhaust gas, PM has a particle diameter of about 0.1 to 0.5 탆. When the cleaning liquid is sprayed in a droplet shape having a particle diameter of 100 to 200 탆, the PM is efficiently agglomerated and aggregated in the cleaning liquid .

[ The injection body 1121 receives the cleaning liquid together with the compressed air and delivers the cleaning liquid to the injection port 1122. The injection port 1122 injects the cleaning liquid toward the exhaust gas.

The first pretreatment injection means 112 is disposed horizontally on a cross section perpendicular to the traveling direction of the exhaust gas on the flow path of the exhaust gas formed by the inner wall 1111 of the preprocessor housing 111, And a plurality of protruding portions are disposed on the inner wall 1111 toward the center of the flow path at predetermined angular intervals. Through this arrangement, the cleaning liquid can be efficiently sprayed to the exhaust gas flowing into the exhaust gas inlet 1112 and proceeding toward the agitating means 113.

The specific shape and arrangement of the first pre-treatment injection means 112 may vary depending on the distribution amount of the first pre-treatment injection means 112 and the overall length design of the preprocessor 11. [

The agitating means 113 is disposed between the first pretreatment injecting means 112 and the second pretreatment injecting means 114 in the interior of the pretreatment housing 111 so that the exhaust gas on the flow path is curved, Preferably a helical flow. In one embodiment of the present invention, the preprocessor housing 111 forms an exhaust gas flow path vertically downward from the top to the bottom, wherein the agitator means 113 is connected to the inlet 1112 through the exhaust gas inlet 1112 So that the flow of the exhaust gas advancing straight downward is changed into a curved shape, preferably a spiral shape.

When the flow of the exhaust gas on the flow path is changed from a straight line to a curved line by the agitating means 113, the flow path becomes long, and as a result, the cleaning liquid injected by the second pre- The contact time of the contact surface is increased. Accordingly, the rate at which the harmful substances such as PM and SOx are trapped by the cleaning liquid in the exhaust gas becomes high. Therefore, it is preferable that the agitating means 113 is disposed adjacent to the exhaust gas inflow portion 1112.

Thus, the agitation means 113 can improve the removal time of harmful substances in the exhaust gas compared to the inner space of the preprocessor housing 111, and can increase the height of the preprocessor 11 without increasing the height thereof, The efficiency of removing harmful substances in the exhaust gas can be improved even if the height is reduced. As a result, it is possible to downsize the facility.

The front wall 1111 of the pre- The stirring means 113 may be arranged to be coupled to the inner wall 1111 of the preprocessor housing 111 through welding or the like.

The body 1131 is a center portion of the stirring means 113 and the wing 1132 is radially coupled to the body 1131 at a predetermined twist angle. The space portion 1133 is a portion formed between each of the vanes 1132 to form a space through which the exhaust gas can pass without colliding with the vanes 1132.

When the agitating means 113 is configured as described above, the flow of the exhaust gas having passed through the agitating means 113 is formed in a spiral shape, and the flow of the exhaust gas formed by the inner wall 1111 of the pre- The first pre-treatment injection means 112 and the second pre-treatment injection means 114 can be formed symmetrically with respect to the moving direction center of the flow path, So that harmful substances in the trapped exhaust gas can flow down on the inner wall 1111 of the housing 111.

If the space portion 1132 does not appear between the vanes 1132, the exhaust gas flowing through the exhaust gas inlet portion 1112 is subjected to excessive pressure loss when passing through the agitation means 113 So that the flow of the exhaust gas is not preferable.

Further, it is preferable that the stirring means 113 is fixed without rotating. This is because the exhaust gas flowing through the exhaust gas inflow portion 1112 generally has a sufficient fluid supply speed toward the pretreatment gas outflow portion 1113 and therefore it is necessary to supply a separate linear energy to the exhaust gas on the flow path There is no.

The second pretreatment injection means 114 is disposed between the agitation means 113 and the pretreatment gas outflow 1113 in the interior of the preprocessor housing 111 and through the agitating means 113, And the cleaning liquid is sprayed on the exhaust gas proceeding spirally.

The second pretreatment injection means 114 is connected to the pretreatment gas outlet 1113 located at the lower portion of the preprocessor housing 111 through the agitation means 113. The second pretreatment injection means 114 is connected to the pre- The cleaning liquid is injected by the first pre-treatment injection means 112 to induce agglomeration of the cleaning liquid in a state of collecting harmful substances such as PM contained in the exhaust gas, thereby enlarging the size of the cleaning liquid, To flow down on the inner wall 1111 of the processor housing 111 or to fall down efficiently to the lower portion of the preprocessor housing 111.

In order to increase the size of the cleaning liquid injected by the first pretreatment injection means 112 and collecting harmful substances such as PM in the exhaust gas as described above, the second pre-treatment injection means 114, It is preferable to inject a cleaning liquid having a larger particle diameter than the cleaning liquid jetted by the jetting means 112. Specifically, it is preferable that the second pre-treatment injection means 114 injects the cleaning liquid in the form of a droplet having a particle diameter of 500 to 1,000 μm.

11 and 12, in an embodiment of the present invention, the second pretreatment injection means 114 includes a rod-shaped injection body 1141 and a plurality of branched water bodies 1141 branched from the injection body 1141 at regular intervals And a plurality of ejection openings 1143 formed at predetermined intervals in each of the ejection bores 1142. [ The jetting body 1141 can receive the cleaning liquid and the compressed air from the cleaning liquid supply unit (not shown) through the cleaning liquid inlet 1114. The jetting body 1141 receives the cleaning liquid together with the compressed air and delivers the jetted liquid to each of the jetting bases 1142. The jetting port 1143 injects the cleaning liquid toward the exhaust gas.

The second pretreatment injection means 114 forms a structure in which the injection ports 1143 for injecting the cleaning liquid are disposed more closely than the first pretreatment injection means 112, This is advantageous in uniformly spraying the cleaning liquid without a square area toward the exhaust gas flowing in the flow path spirally.

The specific shape and arrangement of the second pre-treatment injection means 114 and the like can be controlled in accordance with the distribution amount of the second pre-treatment injection means 114 and the distribution amount of the pre-processor 11 And the overall length design of the device.

The inner wall 1311 is a part forming the flow path of the pretreatment gas in the post-processor housing 131. Referring to FIGS. 6 and 16, the inner wall 1311 forms a flow path of the exhaust gas in the post-processor housing 131 in a cylindrical shape.

The pre-treatment gas inlet 1312 is a portion into which the pretreatment gas flows into the post-processor housing 131. As shown in FIGS. 3 to 5 and 13, the pretreatment gas inlet 1312 is formed at a lower side of the post-processor housing 131, and the pretreatment gas introduced through the pretreatment gas inlet 1312 Is moved upward along a cylindrical flow path formed by the inner wall 1311.

The post-treatment gas outlet 1313 is a portion through which the post-treatment gas, which is a pretreatment gas from which the harmful substances are further removed, is discharged from the post-processor 13. As shown in FIGS. 3 to 5 and 13, the post-treatment gas outlet 1313 is formed in the upper portion of the post-processor housing 131, and is discharged through the post-treatment gas outlet 1313 The process gas can be released to the atmosphere as the removal of harmful substances from the exhaust gas is performed by the pre-processor (11) and the post-processor (13).

The cleaning liquid inlet 1314 is a portion into which the cleaning liquid to be injected from the inside of the post-processor 13 flows. 3 and 13, the cleaning liquid inlet 1314 is connected to the first post-treatment injection unit 135, the second post-treatment injection unit 136, and the cleaning unit 138, respectively, Or formed.

The cleaning liquid outlet 1315 is connected to the first post-processing injection unit 135 or the second post-processing unit 135 to remove harmful substances in the pretreatment gas introduced into the post-processor housing 131 through the pre- And is a portion where the cleaning liquid injected by the second post-treatment injection means 136 is discharged. 3 to 5 and 13, the rinse solution outlet 1315 is formed at the lower end of the post-processor housing 131, and the rinse solution outlet 1315 is connected to the first The cleaning liquid injected by the processing injection means 135 and the second post-processing injection means 136 collects the harmful substances in the pretreatment gas and is moved to the lower end of the post-processor housing 131 to be discharged to the outside do. In order to smoothly discharge the cleaning liquid, the lower end of the post-treatment housing 131 is preferably formed to converge toward the cleaning liquid outlet 1315.

The diffusing means 132 diffuses the pre-treatment gas introduced through the pre-treatment gas inlet 1312 and disposed adjacent to the pre-treatment gas inlet 1312 in the post-processor housing 131. 14 through 16, the diffusing unit 132 is disposed in front of the pretreatment gas inlet 1312 and includes a body 1321 and a fastening unit 1322. [

The body 1321 is a member that covers the front of the pretreatment gas inlet 1312 and has a diffusion portion 1321a through which the pretreatment gas can pass. The body 1321 may be formed of a plate-like member. 15 and 16, the body 1321 is formed so as to vertically cover the front of the pretreatment gas inlet 1312. The upper and lower ends of the body 1321 are connected to the pre- And may be formed in an inclined or curved shape toward the inflow portion 1312 side.

The upper end of the body 1321 is formed to be inclined upward toward the pretreatment gas inlet 1312 and the lower end of the body 1321 is inclined downward toward the pretreatment gas inlet 1312 side Respectively. Through this shape of the body 1321, the pretreatment gas introduced through the pretreatment gas inlet 1312 can be uniformly diffused forward and upward and downward. The body 1321 may be formed not only in an upper portion and a lower portion in a shape that is inclined or curved, but also in a generally curved shape.

The diffusion portion 1321a may include a plurality of through holes, and the diffusion portion 1321a may be formed with a plurality of uniformly formed through holes. However, the diffusion part 1321a is not limited to the through hole, and the diffusion part 1321a may be formed in the form of a slit or the like.

The size and shape of the body 1321 and the shape and the number of the diffusion portions 1321a may vary depending on the processing capacity of the post processor 13 and the like.

The fastening portion 1322 is a portion that is fastened to the fixing portion 1311b formed in the post-processor housing 131 so that the diffusion means 132 can be fixed inside the post-processor housing 131 . 14 and 15, the fastening part 1322 is vertically extended or bent from the left and right ends of the body 1321 toward the pretreatment gas inlet 1312, To be fixed to the interior of the post-processor housing 131 by being fastened to the fixing portion 1311b formed in the post-processor housing 131. [

Since the flow path of the pretreatment gas, which is an exhaust gas whose reduction of harmful substances is primarily performed by the preprocessor 11, is changed by the agitating means 113 in a spiral manner, it flows out to the pretreatment gas outlet 1312 And flows into the pretreatment gas inlet 1312 via the connection portion 12, the gas has a certain amount of rotational energy. Accordingly, the flow of the air into the post-processor housing 131 is concentrated on the inner wall 1311 of the post-processor housing 131 toward the pretreatment gas inlet 1312, It is not uniformly dispersed in the flow path of the pretreatment gas formed in the reaction chamber.

The diffusing unit 132 functions as a nozzle by making the cross sectional area of the pre-treatment gas flow into the post-processor housing 131 to be narrower so that the pre-treatment gas flows into the post-processor housing 131 Thereby allowing uniform diffusion. So that the pretreatment gas can be uniformly dispersed on the flow path of the pretreatment gas formed in the post-treatment housing 131. That is, the pretreatment gas flowing into the packing 133 is uniformly dispersed through the diffusion unit 132, so that the absorption efficiency of the SOx of the pretreatment gas in the packing 133 can be increased, The efficiency can be improved.

14 and 15, two diffusion means 132 are disposed in front of the pre-treatment gas inlet 1312 in succession, whereby the diffusion by the diffusion means 132 is further facilitated It can be made uniform.

The packing 133 is a portion for making a contact area between the cleaning liquid injected by the first post-treatment injection means 135 and the second post-treatment injection means 136 described later and the pretreatment gas large. The packing 133 is disposed on the flow path of the pretreatment gas in the upper portion of the diffusing means 132 in the post-processor housing 131 to increase the vapor / liquid contact area of the pretreatment gas and the cleaning liquid, Or the SOx which is a harmful substance in the pretreatment gas through the cleaning liquid composed of fresh water containing an alkali additive can be smoothly performed.

And a plurality of fillers of the packing 133 are gathered. The fillers may be made of steel, ceramic, plastic, or the like. In addition, the shape of the packing 133 may be a random packing in which packing materials are gathered without a certain pattern, a structured packing having a certain pattern, or the like. The type and shape of the packing 133 may vary depending on the processing capacity and length design of the post-processor 13, and the like.

The packing support means 134 supports the packing 133 from below and diffuses the pretreatment gas. 17 and 18, the packing supporting means 134 covers the flow path of the pretreatment gas and has a step 1311a protruding inwardly on the inner wall 1311 of the post-processor housing 131, And supports the packing 133 placed on the upper part.

The packing support means 134 includes a penetration portion 134a through which the pretreatment gas can pass and a support portion 134b for supporting the packing. Specifically, the supporting portion 134a is a strand having a cross structure, and the penetrating portion 134a is formed as a through hole formed by the supporting portion 134b. That is, the packing support means 134 forms the penetration portion 134a of the mesh structure by the support portion 134b having a cross structure. The pressure loss of the pretreatment gas can be reduced by lowering the resistance through the mesh structure.

The packing support means 134 increases the ratio of the diffusion portion 134a, that is, the ratio of the through holes of the mesh structure, thereby increasing the passage area of the pretreatment gas compared to a general mesh structure to minimize the pressure loss of the pretreatment gas Specifically, it is preferable that the area of the diffusion portion 134a and the vertical projection area of the support portion 134b are formed to be about 2 to 4: 1.

Meanwhile, as shown in FIG. 17, it is preferable that at least a part of the support part 134b has a twisted structure. If the support portion 134b has such a twisted structure, the pretreatment gas impinging on the support portion 134b among the pretreatment gases passing through the penetration portion 134a is changed in the traveling direction along the twisted direction. As a result, the pretreatment gas can be diffused more widely, and more uniform and active pretreatment gas can be dispersed and diffused.

In the present invention, the packing support means 134 does not merely support the packing 133, but also distributes the pretreatment gas introduced into the packing 133 evenly over the whole area of the lower portion of the packing 133 . As a result, the absorption efficiency of the SOx of the pretreatment gas in the packing 133 can be increased through the packing support means 134, and the collection efficiency of other harmful substances can be improved.

It is preferable that the packing support means 134 has a bending structure in which the hill portions 1341 and the valleys 1342 are continuously and continuously arranged. The continuous bending structure in parallel with each other improves the supporting force with respect to the cross sectional area, so that the packing 133 can be more stably supported by the hill 1341. Further, this structure allows the pressure of the pretreatment gas traveling toward the packing 133 to be uniformly dispersed in the packing support means 134, so that the pressure of the pretreatment gas flowing toward the packing 133 from the bottom of the packing 133 Thereby making the flowing pre-treatment gas uniformly diffuse to the lower portion of the packing 133 as a whole.

The first post-processing injection unit 135 is disposed on the flow path of the pre-processing gas among the interior of the post-processor housing 131 and injects the cleaning liquid toward the pre-processing gas. The first post-treatment injection means 135 is disposed on the upper portion of the packing 133 and injects the cleaning liquid toward the packing 133.

The cleaning liquid and the compressed air supplied by the cleaning liquid supply unit (not shown) are supplied to the injection body 1351 through the cleaning liquid inlet 1314. The jetting body 1351 receives the cleaning liquid together with the compressed air and delivers the jetted liquid to each of the jetting bases 1352. The jetting port 1353 injects the cleaning liquid toward the exhaust gas.

The specific shape and arrangement of the first post-processing injection means 135 may vary depending on, for example, the distribution amount of the first post-processing injection means 135 and the overall length design of the post-processor 13.

The second post-processing injection unit 136 is disposed on the flow path of the pre-processing gas among the inside of the post-processor housing 131 to inject the cleaning liquid toward the pre-processing gas, And is operable independently. This independent operation can be performed by the control of the control unit C as shown in Fig. The controller C performs control so that the injections of the cleaning liquids of the first post-processing injection unit 135 and the second post-processing injection unit 136 can be independently performed.

13, 19, and 20, in an embodiment of the present invention, the second post-treatment injection means 136 includes a rod-shaped injection body 1361 and a plurality of injection nozzles 1361, And a plurality of ejection openings 1363 formed at predetermined intervals in the respective ejection bosses 1362. The plurality of ejection bosses 1362 are formed through the ejection body 1361, (Not shown) for supplying a cleaning liquid and compressed air to the cleaning liquid supply unit. The cleaning liquid and the compressed air supplied by the cleaning liquid supply means (not shown) are supplied to the injection body 1361 through the cleaning liquid inlet 1314. [ The jetting body 1361 receives the cleaning liquid together with the compressed air and delivers the cleaning liquid to each of the jetting bases 1362, and the jetting port 1363 ejects the cleaning liquid toward the exhaust gas.

The specific shape and arrangement of the second post-processing injection means 136 may be determined in accordance with the distribution amount of the second post-processing injection means 136 and the distribution amount of the second post-processing injection means 136, as described in connection with the first post- The overall length design of the processor 13, and the like.

The second post-processing injection means 136 independently operates with the first post-processing injection means 135 in that the second post-processing injection means 136 is connected to the first post-processing injection means 135, ≪ / RTI > or at the same time. Therefore, when the amount of the exhaust gas generated by the combustion and the amount of the pretreatment gas introduced from the preprocessor 11 changes according to the load of the engine, it is possible to spray the appropriate cleaning liquid correspondingly thereto, The economical operation of the processor 13 is achieved.

The second post-processing injection means 136 is disposed above the first post-processing injection means 135 at a predetermined interval. When the second post-processing injection means 136 and the first post-processing injection means 135 are disposed on the same horizontal plane of the flow path of the pretreatment gas, the resistance which interrupts the flow of the pretreatment gas becomes large, The second post-processing injection means 136 and the first post-processing injection means 135 are preferably arranged at different heights.

Further, the first post-processing injection means 135 and the second post-processing injection means 136 are disposed at different heights, and are disposed so as to cross each other when they are vertically projected on the flow path of the pretreatment gas Is more preferable. Through this arrangement, the cleaning liquid can be uniformly sprayed on the pretreatment gas on the pretreatment gas flow path without a rectangular area, and removal of toxic substances in the pretreatment gas can be performed more efficiently.

Hereinafter, the mechanism by which the harmful substances in the pretreatment gas are removed through the cleaning liquid injected by the first post-treatment injection means 135 and the second post-treatment injection means 136 will be described below.

The pretreatment gas includes harmful substances such as sulfur oxides (SOx) and PM, which are acidic substances. The first post-treatment injection means 135 and the second post-treatment injection means 136 neutralize The cleaning liquid is sprayed to coagulate and remove. In general, 0.1 ~ 0.5um of PM is first aggregated by fine droplets (100 ~ 200um) and becomes bigger. In addition, a basic cleaning solution is required to neutralize acidic sulfur oxides (SOx). When fresh water is used, a separate alkaline additive is added to induce a neutralization reaction.

At this time, the alkaline additive may be NaOH (sodium hydroxide), Na ₂ CO ₃ (sodium carbonate), or NaHCO ₃ (sodium bicarbonate). The neutralization reaction of sulfuric acid (SOx) by a cleaning liquid containing NaOH is as follows.

_{SO 2 (g) + 2NaOH (} aq) + (1/2) O 2 (g) → 2Na + + SO 4 2- + H 2 O

However, when the present invention is applied to a ship as described above, sea water, which is salt water, may be used as a cleaning liquid. In general, seawater contains salinity such as sodium chloride (NaCl), magnesium chloride (MgCl ₂ ) and potassium chloride (KCl). The anion such as Cl ^- , SO ₄ ^{2 -} and Br ^- And the like. Therefore, if such seawater is used as a cleaning liquid, there is an advantage that neutralization of sulfur oxides (SOx) can be performed without adding an additional alkaline additive.

At this time, the neutralization reaction formula by seawater is as follows. First, it is mixed with sulfur dioxide (SO ₂ ) in gaseous state.

SO _{2 (g)} + H ₂ O ₍₁₎ ↔ H ₂ SO _{3 (aq)}

Next, it reacts with the base in seawater.

2H ₂ SO _{3 (aq)} + OH ^- ↔ 2HSO ₃ ^- _(aq) + H ⁺ _(aq) + H ₂ O _(aq)

^{_{2HSO 3 - (aq) + OH}} - (aq) ↔ ² SO ₃ ^2- _(aq) + H ⁺ _(aq) + H ₂ O _(aq)

That is, sulfur dioxide is absorbed in seawater and becomes a sulfate through the above reaction.

The odd water separating means 137 is disposed on the upper portion of the second post-processing injection means 136 among the inside of the post-processor housing 131 and is connected to the flow of the pretreatment gas via the second post- It is the part that performs the role of separating the micro liquid which flows in the path. The odd water separating means 137 is disposed in a manner such that a rim portion thereof is seated on a step 1311a protruding inwardly from the inner wall 1311 of the post processor housing 131.

The odd water separating unit 137 separates, filters and collects aerosol-type droplets or mist generated by the pretreatment gas and the cleaning liquid. The odd-numbered water separating unit 137 includes a blade May be arranged at a predetermined interval. In addition, the shape of the water separation unit 137 may vary depending on the design of the post-processor 13, temperature and chemical characteristics, and the like.

The cleaning means 138 is disposed on the upper portion of the second post-processing injection means 136 and the lower portion of the water separation means 137 among the interior of the post-processor housing 131, And a cleaning liquid is sprayed toward the cleaning liquid.

13, 21, and 22, in one embodiment of the present invention, the cleaning means 138 includes a bar-shaped injection body 1381 and a plurality of nozzles 1341 branched from the injection body 1381 at regular intervals And a plurality of ejection openings 1383 formed at predetermined intervals in each of the ejection bosses 1382. The ejection bosses 1382 are connected to the respective ejection bosses 1382 through a cleaning liquid and compressed air (Not shown) for supplying a cleaning liquid to the substrate. The cleaning liquid and the compressed air supplied by the cleaning liquid supply means (not shown) are supplied to the injection body 1381 through the cleaning liquid inlet portion 1314. The jetting body 1381 supplies the cleaning liquid together with the compressed air to each of the jetting bases 1382, and the jetting port 1383 ejects the cleaning liquid toward the jetting separating means 137.

The water separating means 136 may be contaminated or occluded during the process of separating, filtering and collecting fine droplets or mist in a state of collecting harmful substances such as PM in the pretreatment gas. The separation means 137 is cleaned by the cleaning liquid, thereby preventing contamination and clogging of the water separation means 136.

In addition, the cleaning means 138 may spray a cleaning liquid to increase the size of fine droplets or mist separated by the water separating means 137, so that droplets of fine droplets or mist that collect harmful substances become large droplets, It can efficiently fall down to the lower portion of the housing 131 or flow downward through the inner wall 1311 of the post-processor housing 131.

The numerical cutoff unit 139 is a part that functions to block the water flowed out through the inner wall 1311 of the post-processor housing 131 and flowing out to the post-process gas outlet 1313. Referring to Figs. 13, 23 and 24, the numerical blocking means 139 includes a blocking wall 1391. In addition, the water blocking means 139 forms a trapping space 1392 for trapping water in the vicinity of the after-treatment gas outlet 1313 to prevent water droplets from flowing out to the outside. The collection space 1392 is formed in such a form that the collected water drops can be dropped downward.

The post-processing gas outlet 1313 is formed on the upper portion of the post-processor housing 131 in an upward direction, and the numerical cutoff unit 139 is disposed below the post-processing gas outlet 1313 in a downward direction And includes an extended blocking wall 1391. The blocking wall 1391 forms a trapping space 1392 between upper end inner walls of the housing 131 of the post-processor. The upper end wall 1311 of the housing 131 of the post-processor is converged toward the post-process gas outlet and is formed in a sloping shape. The blocking wall 1391 effectively forms the trapping space 1392, It is preferable to extend vertically downward to efficiently block the external discharge of the enemy.

The pretreatment gas rises along the flow path of the pretreatment gas formed in the post-treatment unit 13, and is discharged as a post-treatment gas through the post-treatment gas outflow 1313 while the toxic substances are further removed. In this process, some of the number of cleaning liquids collected in the pretreatment gas is collected on the inner wall 1311 of the post-processor housing 131 and moved toward the post-processor outlet 1313.

The water droplets that have moved to the vicinity of the rim of the after-treatment gas outlet 1313 on the upper inner wall 1311 of the post-processor housing 131 are caught by the blocking wall 1391. A trapping space 1392 is formed between the blocking wall 1391 and the inner wall 1311 of the post-processor housing 131 around the post-processing gas outlet 1313 so that water droplets can cohere with each other. The number of particles in the trapping space 1392 coalesces and the size and weight of the particles accumulate in the trapping space 1392 and fall to the bottom of the post-processor housing 131.

Thus, the water blocking unit 139 prevents the water collected from the pre-treatment gas from collecting the harmful substances from being discharged to the outside through the post-processor outlet 1313, and is separated into the lower part of the post-processor housing 131 Let it fall.

Next, the exhaust gas processing apparatus 1b according to the second embodiment will be described.

25, the exhaust gas from an engine or a boiler contains harmful substances such as SOx, NOx, Particulate Matter (PM) and the like, while the exhaust gas according to the second embodiment The exhaust gas treatment apparatus 1b according to the second embodiment may include a housing 171 in which a plurality of means for reducing the harmful substances are provided step by step.

Referring to FIGS. 26 and 27, the housing 171 may have various shapes in the form of a large barrel with an empty interior. In general, however, the housing 171 has a cylindrical housing 171, A gas inflow portion 1712 through which the exhaust gas enters and a cleaning liquid outlet portion 1715 through which the sprayed cleaning liquid escapes and a gas outlet portion 1713 through which the exhaust gas exits from the upper portion .

The inner wall surface 1711 may include a vertical surface 1711a which extends upward and downward and an inclined surface 1711b which is bent and extended from the vertical surface 1711a in the vicinity of the gas outflow portion 1713, The inner wall surface 1711 may have a function of rinsing the cleaning liquid introduced from the later-described injection means 173 or the like along the flow of the exhaust gas.

The gas inlet 1712 may include a gas inlet pipe 1712a that protrudes inward of the housing 171 and communicates with one side of a diffusion unit 172 which will be described later. Is formed as a hollow hollow cylinder having a function as a passage through which exhaust gas can flow.

The cleaning liquid outlet 1715 includes a cleaning liquid outlet pipe 1715a extending from a bottom surface of the housing 171 to a lower portion of the housing 171 by a predetermined length, In many cases, the inside is formed as a hollow hollow cylinder for discharging the cleaning liquid. In case of installing on a ship, it is possible to smoothly discharge the cleaning solution on one side according to the inclination of the ship without a separate bottom surface inclination due to a rolling phenomenon rolling the hull to the left and right and a pitching phenomenon to lean forward and backward.

The gas outflow portion 1713 is formed with a large hole in the exhaust gas treatment device 1b according to the second embodiment so that the clean gas from which harmful substances are removed is discharged to the atmosphere, And may communicate with the water cutoff means 178 to block the water droplets that rise on the inner wall surface 1711.

26 to 55, the exhaust gas flowing into the housing 171 of the exhaust gas treating apparatus 1b is cleaned in stages to finally remove sulfur oxides (SOx) and particulate matter (PM) I will explain various means of discharging cleaned gas.

26 and 27, the exhaust gas treating apparatus 1b is provided with diffusing means 172 (see FIG. 17) for distributing the exhaust gas evenly inside the housing 171, A dispensing means 173 for spraying the cleaning liquid on the upper side thereof, a dispensing means 174 for spraying the exhaust gas on the upper side of the injection means 173, a multi-injection means 175), numeral separation means (176) for guiding the flow of the exhaust gas on the multiplying means (175), numeral collecting means (177) for collecting the numeral water separated from the lower portion of the numerical separating means (176) And a numerical aperture blocking means 178 for dropping the water droplets riding on the inner wall surface 1711 in the vicinity of the gas outlet portion 1713.

Referring to FIGS. 28 to 31, the diffusion unit 172 has a function of uniformly dispersing the exhaust gas introduced from the gas inlet 1712 into the housing 171, A diffuser 1721 and an exhaust passage 1722 for exhausting the cleaning liquid, which is accumulated inside the gas diffuser 1721, without obstructing the flow of the exhaust gas.

28 and 29, the gas diffuser 1721 is configured such that the inside thereof is in the form of an empty thin-film light narrowing so that the inner surface 1721a and the outer surface 1721b and the boundary between the two surfaces 1721a and b And a blocking portion 11721d extending outwardly of the gas diffuser 1721 along the periphery of the outer side surface 1721b.

The outer side surface 1721b has a function that the exhaust gas flowing through the gas inlet portion 1712 rises and is widely dispersed inside the housing 171. [

In the prior art, gas diffusers are sometimes provided on the upper side of the gas inlet. However, the cleaning liquid having a lower narrowing width that becomes narrower toward the upper side flows down along the surface of the gas diffuser and obstructs the flow of the exhaust gas . Thereby, pressure loss of the exhaust gas is generated thereby to weaken the function of the entire exhaust gas processing apparatus. In addition, in many cases, the lower crucible has a triangular or conical shape. The exhaust gas introduced from the gas inlet part bypasses the lower side of the horn and spreads to the inside of the housing to form an upward flow. Causing a large pressure loss. Although the exhaust gas treatment apparatus is important in terms of how much pressure loss (mmAq / m) per unit height is quantified and used as an index for performance, the conventional art has a problem that the pressure loss It was a bar.

Accordingly, the gas diffuser 1721 according to the present invention includes a shape that widens toward the upper end, and the exhaust gas that has entered through the gas inlet 1712 is gradually widened along the outer surface 1721b of the gas diffuser 1721, The exhaust gas can be widely dispersed in the housing 171 without pressure loss. In particular, it is preferable that the gas diffuser 1721 in the shape of the upper limit of the light includes an inverted conical shape.

The inner side surface 1721a has a function of collecting the cleaning liquid sprayed from the spraying means 173 to be described later and collecting downwardly so as to collect downwardly. The flow of the gas is not disturbed and the pressure loss can be prevented.

The blocking portion 1721d is formed to extend outward along the periphery of the outer surface 1721b and is located below the edge 1721c. The blocking portion 1721d includes a first surface 172d-1 that is horizontally deployed, And a second surface 1721d-2.

Referring to FIG. 30, the exhaust gas treating apparatus 1b may be used in a ship to confirm a pitching phenomenon in which a hull is inclined forward or backward by a wave, or a rolling phenomenon in which a curve is tilted to the left or to the right . At this time, the housing 171 also tilts forward, backward, left and right. At this moment, when the gas diffuser 1721 is inclined so that the outer side surface 1721b extends beyond the vertical direction, the cleaning liquid jetted from the jetting means 173, 1712). If the cleaning liquid that has entered the gas inlet 1712 flows backward into the engine E or the boiler B, there is a possibility that a serious trouble such as a device failure occurs. Therefore, in order to prevent such a phenomenon, the blocking portion 1721d should be designed to have a size considering the size, rolling and pitching angle of the ship. More specifically, by varying the length of the first surface 1721d-1 and the length of the first surface 1721d-2, the degree of protrusion from the outer surface 1721b is adjusted so that even when the hull is tilted, And prevents backflow to the gas inlet 1712. At this time, the angle at which the outer surface 1721b is developed is preferably designed in consideration of rolling and pitching.

In addition, when the rolling and pitching occurs, the cleaning liquid accumulated in the blocking portion 1721d may be poured to the bottom of the housing 171 rather than the gas inflow portion 1712. For this, the development angle of the second surface 1721d-2 is designed in consideration of rolling and pitching.

The discharge passage 1722 has a function of discharging the cleaning liquid collected on the inner side surface 1721a of the gas diffuser 1721 to the bottom surface of the housing 171 to prevent overflow of the cleaning liquid, 1721 from the lower side to the inner side surface 1721a. At this time, the discharge passage 1722 is formed such that the gas inlet 1712 protrudes inside the housing 171 and extends to the inside of the extended gas inlet pipe 1712a. In order to discharge the cleaning liquid, the gas inlet pipe 1721a, And an outlet 1722a communicating with the inner surface of the base plate 1720. [ In this case, in order for the discharge port 1722a to be formed at one side of the gas inlet pipe 1712a, the discharge passage 1722 is formed in an inclined form from the lower side of the gas diffuser 1721 to the inner side of the gas inlet pipe 1712a As shown in Fig.

The cleaning liquid discharged from the discharge passage 1722 is accumulated on the bottom surface of the housing 171. The cleaning liquid collected therefrom is supplied to the cleaning liquid discharge portion 1715 extending from the bottom of the housing 171 downward at a predetermined angle To the outside of the exhaust gas treatment device 1b. At this time, even if the rinse solution outlet 1715 is biased to one side only and there is no separate inclined surface on the bottom surface of the housing 171, the pitching phenomenon and rotation The entire housing 171 is inclined by a rolling phenomenon in which the hull is inclined to the left and right due to the inclination of the hull, so that it is possible to smoothly discharge the cleaning liquid and prevent accumulation of excessively accumulated on the floor surface. The manner in which the housing 171 is lifted in this way can be seen in more detail in Fig.

31, the cleaning liquid collected on the inner surface 1721a of the gas diffuser 1721 is not influenced by the flow of the exhaust gas passing through the gas inflow pipe 1712a, thereby preventing pressure loss (Dotted line), and the exhaust gas is naturally dispersed (indicated by a solid line) inside the housing 171 without pressure loss by the structure.

32 to 35, the spraying means 173 has a function of spraying a cleaning liquid from above the diffusion means 172 and cleaning the exhaust gas including sulfur oxides (SOx) and PM. Particularly, Side injection means 1731 for injecting the exhaust gas in the direction of the flow direction of the exhaust gas.

Referring to FIG. 32, the lateral jetting means 1731 may include a jetting body 1731a and a jetting port 1731b, which are configured to jet a cleaning liquid onto the exhaust gas.

The injection body 1731a is connected to the inner wall surface 1711 of the housing 171 as a rod-shaped supply pipe for supplying the cleaning liquid. When the housing 171 is cylindrical, the injection body 1731a may also be circularly distributed Particularly, if it is located in the space formed by being inserted into the inner wall 1711 outwardly at a certain depth, the injection means 1731 itself prevents the flow of the exhaust gas and prevents the pressure loss due to the structure.

The jetting port 1731b is formed at one end of the jetting body 1731a to jet the cleaning liquid, and is formed toward the side surface to jet the cleaning liquid to the side surface.

The exhaust gas generated by the combustion in the engine E or the boiler B includes harmful substances such as sulfur oxides (SOx) and PM which are acidic substances. The injecting means 173 neutralizes or coheses these harmful substances Thereby spraying a cleaning liquid to be removed. In general, 0.1 ~ 0.5um of PM is first aggregated by fine droplets (100 ~ 200um) and becomes bigger. In order to neutralize acidic sulfur oxides (SOx), a basic cleaning liquid is required. In the case of using fresh water, a separate alkaline additive is added to induce a neutralization reaction.

Wherein the alkaline additive is capable of such as NaOH (sodium hydroxide), Na ₂ CO ₃ (sodium carbonate) or NaHCO ₃ (sodium bicarbonate). The neutralization reaction of sulfuric acid (SOx) by a cleaning liquid containing NaOH is as follows.

_{SO 2 (g) + 2NaOH (} aq) + (1/2) O 2 (g) → 2Na + + SO 4 2- + H 2 O

However, when the exhaust gas treatment device 1b is installed on a ship operated on the sea, sea water, which is salt water, may be used. In general, seawater contains salinity such as sodium chloride (NaCl), magnesium chloride (MgCl ₂ ) and potassium chloride (KCl). The anion such as Cl ^- , SO ₄ ^{2 -} and Br ^- And the like. Therefore, if such seawater is used as a cleaning liquid, there is an advantage that neutralization of sulfur oxides (SOx) can be performed without adding an additional alkaline additive.

At this time, the neutralization reaction by seawater is as follows, first mixed with gaseous sulfur dioxide (SO ₂ ) water.

SO _{2 (g)} + H ₂ O ₍₁₎ ↔ H ₂ SO _{3 (aq)}

Next, it reacts with the base in seawater.

2H ₂ SO _{3 (aq)} + OH ^- ↔ 2HSO ₃ ^- _(aq) + H ⁺ _(aq) + H ₂ O _(aq)

^{_{2HSO 3 - (aq) + OH}} - (aq) ↔ ² SO ₃ ^2- _(aq) + H ⁺ _(aq) + H ₂ O _(aq)

That is, sulfur dioxide is absorbed in seawater and becomes a sulfate through the above reaction.

The spraying means may spray a dual fluid containing compressed air in addition to the washing liquid composed of seawater or fresh water to spread the washing liquid in the housing 171 to increase the area of contact with the exhaust gas to improve the washing efficiency.

Further, the cleaning liquid and the compressed air may have a function of cooling the harmful substances such as SOx or PM in the exhaust gas by lowering the temperature of the exhaust gas itself. Generally, the exhaust gas generated as a by-product of combustion in the engine E and the boiler B is a high-temperature gas having a temperature of about 250 to 300 degrees at the time when it flows into the housing 171. If such a high temperature exhaust gas is directly discharged into the atmosphere, many problems arise, and various structures in the housing 171 may cause heat injury, and the cleaning liquid may be rapidly evaporated, causing a trouble in the cleaning operation . Also, even when the cleaning liquid is sprayed at a high temperature, there is a possibility that the PM may pass without passing through the agglomerated state. Therefore, the injecting means 173 injects seawater or a two-fluid mixture of fresh water and compressed air into the exhaust gas of high temperature entered into the housing 171 through the gas inlet 1712 to cool the temperature to about 50 to 60 degrees .

The function of the above-described injection means 173 is more effective when the contact area with the exhaust gas and the contact time are increased. The spraying means of the conventional exhaust gas processing apparatus injects the cleaning liquid so as to coincide with the flow direction of the exhaust gas, And the contact time was short. Therefore, there has been a problem that the cleaning operation and the cooling operation can not be effectively performed.

In addition, the exhaust gas treatment apparatus for cleaning and cooling sulfur oxides (SOx) and PM has a very long shape such as exceeding 5 m in the vertical direction. When installed in a power plant on the ground, Due to the large volume, it limits the design of the ship and damages the aesthetics. However, the conventional injection means has a problem that the exhaust gas processing device itself can not be made longer in order to ensure a sufficient contact area by spraying the cleaning liquid in parallel with the exhaust gas flow direction.

In this case, the flow of the exhaust gas is disturbed to the front, resulting in a great pressure loss. As described above, since the degree of pressure loss of the exhaust gas treatment device is numerically expressed (mmAq / m unit), it is an important factor to be used as an index indicating the performance thereof.

32 to 34, the exhaust gas treatment apparatus 1b includes a lateral injection means 1731 inside the housing 171 to inject a cleaning liquid and compressed air from the side of the flow of the exhaust gas, The sufficient contact area and contact time of the exhaust gas and the cleaning liquid can be ensured without increasing the length of the exhaust gas 171, so that the neutralization reaction of sulfur oxides (SOx), the agglomeration of PM, and the cooling reaction of the exhaust gas can be smoothly generated. Particularly, when installed on the lower side of the inclined portion 1741 of the distributing means 174 to be described later, the cleaning liquid is sprayed to the point where the vortex is generated, so that the exhaust gas and the cleaning liquid can be actively mixed. Moreover, when the temperature is lowered by the cooling, the air is shrunk and the volume is reduced, so that there is also an effect that the PM particles agglomerate and grow relatively. Further, since there is a force on the side surface, there is an advantage that no pressure loss is caused in the flow direction of the exhaust gas. Preferably, it is preferably injected perpendicularly to the flow direction of the exhaust gas.

In addition, referring to Fig. 35, it is possible to maximize the contact area with the exhaust gas and the contact time by distributing the two liquids of the cleaning liquid and the compressed air in a conical shape, thereby increasing the efficiency of the work.

36 to 39, the distributing means 174 is located on the upper side of the injection means 173 and is formed in a mesh structure including a plurality of through holes 174a, which are small holes, An inclined portion 1741 and a guide portion 1742 extending downward from the lower side of the inclined portion 1741. [

Referring to FIGS. 36 and 37, the inclined portion 1741 has an upward light-narrowing shape that becomes increasingly closer to the upper side, which draws the flow of the exhaust gas to the center and forms a swirling flow below the inclined portion 1741 To mix with the cleaning liquid.

The exhaust gas treatment device 1b is required to increase the contact area and contact time evenly dispersed inside the housing 171 for effective reaction between the cleaning liquid and the exhaust gas. It tends to rise toward the inner wall surface 1711 of the housing 171 due to the influence of the gas diffuser 1721 of the housing 171. Therefore, in order to return the upward flow of the exhaust gas deflected toward the inner wall surface 1711 toward the center, a large number of small through holes 174a are formed, and the exhaust gas is broadened toward the upper side as a whole. With this configuration, the exhaust gas deflected toward the inner wall surface 1711 of the housing 171 passes through the plurality of through holes 174a inclined downward toward the center, is refracted inward, and the flow is dispersed to the center. Also, the flow of some exhaust gas that has not risen through the through hole 174a collides with the lower surface of the inclined portion 1741 and forms a vortex flow (vortex) in the process of detouring downward, so that the mixture of the cleaning liquid and the exhaust gas The neutralization reaction of sulfur oxides (SOx) and the agglomeration reaction of PM actively occur, and the cleaning effect is further improved.

Referring to FIGS. 36 and 38, the guide portion 1742 includes an inlet hole 1742a, which is a large hole in the middle, and has an inner hollow shape so that a large amount of exhaust gas can pass therethrough.

Mentioned inclined portion 1741 itself has a large effect of dragging the exhaust gas flow toward the center of the inner wall surface 1711 to the center but includes a large inflow hole 1742a at the center for performing a more reliable function. With this configuration, the exhaust gas whirled by the inclined portion 1741 is uniformly distributed to the center side to increase the cleaning efficiency. The vertically formed guide portion 1742 guides the flow of the exhaust gas so that such a distribution effect can be generated more effectively. The flow of the exhaust gas can be seen in FIG.

40 to 43, the multiple injection means 175 is located on the upper side of the distribution means 174, and a plurality of injection means are arranged vertically.

Referring to FIG. 41, the multiple injection unit 175 may include a first injection unit 1751, a second injection unit 1752, and a third injection unit 1753.

42, the first injection means 1751 includes a rod-shaped injection body 1751a, a plurality of injection belts 1751b branching at a predetermined interval from the injection body 1751a, And a plurality of ejection openings 1751c formed at regular intervals on the base 1751b.

The jetting body 1751a is connected to the inner wall surface 1711 of the housing 171 as a supply pipe for supplying a cleaning liquid from the outside.

The jetting base 1751b is branched from the jetting body 1751a and is configured to jet the cleaning liquid into a wider space. The jetting base 1751b is disposed to be offset from the jetting base 1752b of the second jetting means 1752, The area can be maximized. In addition, it eliminates the dead zone of the exhaust gas and prevents the harmful substances from being released to the atmosphere as it is.

A plurality of jetting ports 1751c are formed at predetermined positions of the jetting base 1751b to jet a mixture of the cleaning liquid and the compressed air.

Referring to FIG. 43, the second injection means 1752 similarly includes the injection body 1752a, the injection stage 1752b, and the injection orifice 1752c, but the respective injection stages are arranged to be shifted as described above. With this configuration, the contact area between the cleaning liquid and the exhaust gas injected by each of the injection means is maximized, so that the neutralization reaction of sulfur oxides (SOx) and the agglomeration reaction of PM can be effectively produced.

The first injecting means 1751 and the second injecting means 1752 can be selectively operated according to the operation states of the engine E, the boiler B, and the like. At this time, the controller 1754 may further include a controller 1754 for the selective injection to control the injection according to the driving state of the engine or the boiler.

Generally, the engine (E) used in ships changes its operation rate constantly, such as when the ship is accelerating or decelerating, when the drill for drilling the seabed is operated, or when the amount of power system used increases. Also, the boiler (B) is rarely used in hot summer days, but when it is cold winter, it is often used to maintain the temperature of the crew members and to control the temperature of the cargo. Thus, the running state of the engine E or the boiler B is continuously changed, which means that the amount of combustion of the fuel is changed. When the amount of combustion of the fuel changes, the amount of exhaust gas generated by combustion also varies. The amount of harmful substances such as sulfur oxides (SOx) and PM is also changed when the exhaust gas amount is changed.

However, even if the discharge amount of the exhaust gas is reduced, an unnecessary cleaning liquid is sprayed if the amount of the cleaning liquid sprayed from the discharge gas processing device 1b is constant. In order to inject the cleaning liquid, the pump must be operated. Since the pump is operated by electric power, unnecessary injection means waste of unnecessary electric power. In addition, unlike the case of spraying a washing solution using weak water with a pH of about 8.3, it is necessary to add an alkaline additive in case of making a washing solution using fresh water, and when an unnecessary washing solution is sprayed, the alkaline additive is also wasted. Therefore, there is a need to adjust the injection amount of the cleaning liquid corresponding to the exhaust amount of the exhaust gas, which varies depending on the operation state of the engine E or the boiler B.

The multiple injection means 175 of the exhaust gas processing apparatus 1b selectively operates the first injection means 1751 and the second injection means 1752 in accordance with the operation ratios of the engine E and the boiler B The above problems can be solved by spraying the cleaning liquid. With this configuration, when the amount of exhaust gas discharged is small, only a part of the injecting means is activated to inject the washer fluid, thereby preventing waste of electric power for operation of the pump and saving alkaline additive.

The multiple injection means 175 further includes a third injection means 1753 above the first injection means 1751 and the second injection means 1752 to enable efficient cleaning of harmful substances in the exhaust gas .

At this time, like the relation between the first injection means 1751 and the second injection means 1752, the third injection means 1753 is staggered with the second injection means 1752 to enlarge the contact area between the cleaning liquid and the exhaust gas It is possible to more effectively induce the neutralization reaction of sulfur oxides (SOx) and the coagulation action of PM.

The third injecting means 1753 is also selectively operated corresponding to the amount of exhaust gas discharged depending on the operation rate of the engine E or the boiler B to prevent waste of electric power of the pump for supplying the washing liquid, You can save.

The first spraying means 1751, the second spraying means 1752 and the third spraying means 1753 spray not only the cleaning liquid composed of seawater or fresh water but also the compressed air, So that the contact time and contact area between the sulfur oxides (SOx) and the cleaning liquid can be increased to facilitate the neutralization reaction. Also, the cooling action by the compressed air can be more effectively achieved.

44 to 51, the numerical separating means 176 is located on the upper side of the multiple injection means 175, and is roughly divided into two types.

44, the first type includes an induction portion 1761 that is cleaned by a cleaning liquid and guides the flow of the exhaust gas that has been raised, and at least one horizontal blade (not shown) that forms a spiral flow of the exhaust gas raised through the induction portion 1761. [ (1762a), a stopper (1764) for blocking the flow of exhaust gas in the upper and lower portions of the vane (1762a) and flowing in a predetermined direction, a first negative pressure preventing means (1763a) for preventing differential pressure from above the horizontal vane (1762a) ).

Referring to FIG. 48, the second type includes an induction portion 1761 that is cleaned by a cleaning liquid and guides the flow of the exhaust gas that has been raised, and a twist blade 1762b that forms a helical flow of the exhaust gas raised through the induction portion 1761 And second negative pressure preventing means 1763b for preventing differential pressure on the upper side and the side surface of the torsion blade 1762b.

Referring to Figs. 44, 45, 48 and 49, the guiding portion 1761, which is a common configuration of the two types, has a lower guiding plate 1761a narrowed toward the upper side, And a guide tube 1761b extending upwardly.

The induction plate 1761a preferably has a hollow truncated conical shape and has a function of guiding the exhaust gas raised via the multiple injection means 175 to the center. At this time, in order to send only one side without leaking exhaust gas, it is possible to construct airtightly to fit into the inner wall surface 1711 with a circumference corresponding to the end surface of the housing 171.

The induction pipe 1761b extends upward from the upper side of the induction plate 1761a and functions as a passageway for upwardly moving the exhaust gas led to the one side by the induction plate 1761a. As shown in FIG.

Referring to FIG. 45, one or more horizontal wings 1762a of the first type are provided on a lower plate 1764b to be described later, and are laid sideways with a constant curvature. The horizontal vanes 1762a are spaced apart from each other by a predetermined distance so that exhaust gas can pass through the horizontal vanes 1762a. The horizontal wing 1762a of this shape induces a radial flow in which the exhaust gas raised through the induction pipe 1761b flows in a spiral manner to the side.

The cleaning liquid jetted from the multiple jetting unit 175 exists in a small number of droplets in the exhaust gas, and includes many harmful substances such as SOx and PM. Accordingly, the vane 1762 forms a spiral flow of the exhaust gas, and the centrifugal force generated by the vane 1762 causes the relatively heavy water to be outwardly directed to the inner wall surface 1711, Thereby separating the exhaust gas from the water droplet.

In addition, all the horizontal blades 1762a may be configured as a stationary stator. When rotating like a compressor, the speed becomes excessively high, and the cleaning operation becomes inefficient because the contact time between the exhaust gas and the cleaning liquid is insufficient.

The stopper 1764 may include an upper plate 1764a and a lower plate 1764b that cover the upper and lower sides of the horizontal vane 1762a to prevent the exhaust gas from escaping up and down without forming a spiral flow . The upper plate 1764a and the lower plate 1764b may have the shape of a circular plate when the horizontal vanes 1762a are circularly distributed.

When the exhaust gas flows into the spiral by the vane 1762, a centrifugal force is applied and the fluid is concentrated to the inner wall surface 1711 and the center is relatively lowered in pressure. In this case, the spiral flow may not be formed properly due to the differential pressure, or the pressure may be lower than the air on the upper side, which may interfere with the upward movement. Therefore, there is a need to arrange the mass at the center of the spiral flow to prevent sound pressure.

Accordingly, the first negative pressure preventing means 1763a is located above the horizontal vane 1762a to prevent differential pressure due to the spiral flow of the exhaust gas, and preferably has a conical shape from above the upper plate 1764a. The flow of the exhaust gas by this can be seen in FIG.

48 and 50, at least one torsion blade 1762b is distributed along the outer surface of the induction pipe 1761b and the inner wall surface 1711 of the housing 171, starting from the outer surface of the induction pipe 1761b, In a radial direction. At this time, an angle (stagger angle a) between the chord of the root surface contacting the outer surface of the induction pipe 1761b and the axis of the induction pipe 1761b; And an angle (stagger angle b) between the chord of the tip surface and the axis of the induction pipe 1761b; May be configured in a twisted fashion as a whole. Generally, b is formed larger than a. The twisted wing 1762b guides the oblique flow of the air that has passed through the guide tube 1761b and spirals downward. Preferably, the stagger angle continuously increases from the root to the tip, thereby inducing the flow of the exhaust gas more effectively.

Referring to FIG. 50, the twist wings 1762b are spaced apart from each other by a pitch of 30 degrees so that a sufficient space is formed between the wings and the wings when viewed from above. Thereby minimizing the pressure loss of the exhaust gas exiting the induction pipe 1761b and creating a spiral bypass flow. Also, all of the torsional vanes 1762b may be composed of a stationary stator. If the torsion vane 1762b is rotated like a compressor, the speed becomes excessively high and the contact time between the exhaust gas and the cleaning liquid is not sufficient.

The second negative pressure preventing means 1763b extends to the lower portion of the torsional vibration damper 1762b so as to allow the exhaust gas raised through the induction pipe 1761b to pass downwardly, The pipe 1761b can be covered. As a result, when the number of the cleaning liquid including the harmful substances in the exhaust gas is separated by the centrifugal force, it can be effectively separated downward. The second negative pressure preventing means 1763b is in the form of a hollow cylinder for the flow of the exhaust gas, and preferably has a cylindrical shape to effectively prevent differential pressure. Or the first negative pressure preventing means 1763a on the upper side of the second negative pressure preventing means 1763b. The spiral bypass flow of the exhaust gas with such a configuration can be confirmed in more detail in Fig.

52 and 53, the water collecting means 177 collects the water separated from the exhaust gas at the bottom of the water separating means 176 and surrounds the induction pipe 1761b, A diaphragm 1772 having the same configuration as the diaphragm 1772, a diagonal plate 1772 having the same configuration as or parallel to the diaphragm 1772, a drop tube 1773 extending downward from one side of the diagonal plate 1772, And a collecting box 1774 located at the lower end of the tray 1773.

The numerical separator 176 separates the water in the exhaust gas, and uses the centrifugal force to deflect the cleaning liquid containing harmful substances such as SOx and PM toward the inner wall surface 1711 side. The separated water droplets are required to be dropped down before they rise again under the influence of the flow of the exhaust gas. At the same time, it is necessary to prevent the exhaust gas from rising up into the passage through which the water drops fall.

Referring to FIGS. 46, 50 and 52, the partition plate 1771 includes a plurality of through holes 1771a near the periphery thereof to drop the water drops separated from the water separating means 176. At this time, if the exhaust gas treatment device 1b is installed on the ship, the water can be flowed into the through hole 1771a without any inclination of the diaphragm 1771 due to rolling and pitching of the hull.

The swash plate 1772 is extended to maintain a predetermined inclination so that the water drops away from the through holes 1771a of the partition plate 1771 can flow outwardly, and preferably has a conical shape. One or more drop holes 1772a are provided on one side for dropping the water droplets that have flowed out to the outside, preferably four in total, one for every 90 degrees.

The drop pipe 1773 is extended downward from the drop hole 1772a formed at one side of the swash plate 1772 to drop the water drop to the bottom of the housing 171. [ It is preferable to have a cross section coinciding with the drop hole 1772a. In the case of FIG. 52, since the drop hole 1772a is formed of a triangle, the drop pipe 1773 also has a shape of a triangular pillar.

52 and 53, the collecting cylinder 1774 is a cylinder for collecting the water droplets descended by the dropping tube 1773 so that the sprayed liquid below the third injecting means 1753 is always filled . When the dropping pipe 1773 extends to the inside of the collecting cylinder 1774 and is completely immersed in the washing liquid sprayed from the third injecting means 1753, the exhaust gas rises on the dropping pipe 1773, It is possible to prevent it from being discharged without going through.

54 and 55, the numerical blocking means 178 may include a first blocking means 1781 and a second blocking means 1782, each located above the numerical separating means 176, Some of the water drops separated from the gas are prevented from falling on the inner wall surface 1711 of the housing 171 under the influence of the flow of the exhaust gas without dropping, thereby preventing the water containing the harmful substances from being discharged into the atmosphere.

Since the cleaning liquid composed of the seawater or the fresh water injected from the injection means 173 and 175 has the function of neutralizing the sulfur oxides SOx and coagulating the PMs, the washing liquid water level present in the upper portion of the exhaust gas treatment device 1b is discharged It contains various harmful substances contained in gas. If the water droplets of the cleaning liquid are discharged together with the cleaned exhaust gas into the atmosphere, the exhaust gas treatment device 1b itself becomes meaningless, so that the atmospheric release of the water should be prevented.

To this end, the horizontal blade 1762a of the numerical separating means 176 induces a spiral flow of the exhaust gas including the washing liquid numerical value, and deflects the water droplet, which is relatively heavy liquid by the centrifugal force, toward the inner wall surface 1711 side of the housing 171 . Or the inclined wing 1762b of the numerical separating means 176 bypasses the exhaust gas and induces the spiral flow so that the numerical value is shifted to the lower side of the inner wall surface 1711 by the centrifugal force. The water droplets of the cleaning liquid leaning toward the inner wall surface 1711 drop downward under the action of gravity, are collected by the water collecting means 177, fall down to the bottom of the housing 171, and are prevented from being discharged into the atmosphere.

However, in spite of the water collecting means 177, a part of the washing liquid separated by the water separating means 176 rises by the pressure difference without falling after being struck on the inner wall surface 1711 of the housing 171 And flows upward on the inner wall surface 1711 toward the upper side of the housing 171 under the influence of the exhaust gas flow. There is a need to block the discharge of harmful substances by blocking the water droplets ascending from the inner wall surface 1711 to the upper side of the housing 171 and discharging it to the atmosphere.

54, the inner wall surface 1711 includes a vertical surface 1711a extending vertically and vertically from the vertical surface 1711a in the vicinity of the gas outflow portion 1713, and an inclined surface 1711b ). The slope 1711b can cut off the water droplet that rises along the vertical surface 1711a due to the influence of the exhaust gas to some extent. However, when the exhaust gas meets the inclined surface 1711b, the inclined surface 1711b is bent and flows along the inclined surface, so that there is a concern that the numerical value affected by the exhaust gas also rises along the inclined surface 1711b and is released to the atmosphere.

In order to prevent this, the first blocking means 1781 may include a blocking wall 1781a extending downward from one side of the inclined surface 1711b. The blocking wall 1781 is distributed in the form of a thick band along the boundary of the gas outflow portion 1713. When the gas outflow portion 1713 is circular, the blocking wall 1781a has a hollow cylindrical shape. As a result, the number of pieces of water that have risen along the inner wall surface 1711 flows down along the blocking wall 1781a via the inclined surface 1711b and there is no surface to be lifted further at the lower end of the blocking wall 1781a. Falls. Preferably, the blocking wall 1781 is expanded in a direction in which gravity acts to further improve the blocking effect. This numerical flow can be seen in more detail in FIG.

The second blocking means 1782 is located below the first blocking means 1781 and may include a downward sloping surface 1782b and another blocking wall 1782a.

The lower inclined surface 1782b is bent toward the center at a predetermined angle from one side of the vertical surface 1711a of the housing 171. The downward inclined surface 1782b has a function of guiding a water drop rising on the vertical surface 1711a to the blocking wall 1782a . At this time, it is preferable that the angle is formed larger than 90 degrees and the inclined surface is inclined downward to smoothly guide the number.

The blocking wall 1782a extends downward from the end of the lower inclined surface 1782b, and is preferably developed in a direction in which gravity acts. The water drops falling down on the downward sloping surface 1782b meet the blocking wall 1782a and descend vertically and the surface of the blocking wall 1782a no longer rides on the end of the blocking wall 1782a and falls downward by gravity.

By the two blocking means 1781 and 1782, the water droplets of the cleaning liquid including the harmful substances such as SOx and PM can be prevented from being released to the atmosphere together with the clean gas.

Based on the above-described configuration, exhaust gas generated by combustion in an engine or a boiler passes through the exhaust gas treatment device 1b, and harmful substances such as SOx and particulate matter (PM) The process of conversion to gas will be described with reference to FIGS. 26 and 27.

Referring to Figs. 26 and 27, the exhaust gas enters the inside of the housing 171 through the gas inlet portion 1712. Fig. The mixture of the washing liquid and the compressed air injected from the injecting means 173 soon causes the PM in the exhaust gas to cohere with the diffusing means 172 on the upper side of the gas inlet pipe 1712a. At this time, the exhaust gas by the diffusion means 172 forms a flow deflected toward the inner wall surface 1712, passes through the distributing means 174 and is evenly distributed to the center. Neutralization of sulfur oxides (SOx) and agglomeration of PM are caused by the cleaning liquid jetted from the multiple injection means 175 and the spiral flow formed by the water separating means 176 Uses a centrifugal force to separate the water droplets outward. The separated water droplets fall by the water collecting means 177, and the exhaust gas turns helically and continues to rise. However, some of the water drops that can not fall due to the exhaust gas flow and rise along the inner wall surface 1711 are blocked by the blocking means 178 so as to be prevented from being released to the atmosphere.

Through the above-described structure and process, the exhaust gas separates harmful substances such as sulfur oxides (SOx) and particulate matter (PM), and is released into the atmosphere as a clean gas. However, even if the harmful substances are separated, it is necessary to confirm whether they are properly treated by the exhaust gas treatment device and released to the atmosphere. Therefore, an apparatus for monitoring such an exhaust gas treatment apparatus will be described below.

56 is a diagram illustrating a monitoring apparatus for a sulfur oxide removal apparatus of a ship having an automatic purging function according to an embodiment of the present invention. Hereinafter, description will be made with reference to FIG.

The monitoring device 19 includes a collecting section 191, a filter section 192, a pump 193, an analyzing section 194, and a gas injecting section 195.

The collecting unit 191 is configured to collect the exhaust gas to be discharged, and preferably the exhaust gas treated in the exhaust gas treating apparatus 1 is coupled to a gas outlet port to the atmosphere, It can be seen as a configuration that captures a part. The collecting unit 191 is connected to a filter unit 192 to be described later and the exhaust gas collected through the collecting unit 191 is filtered by the filter unit 192 to be analyzed by an analyzing unit 194 As it flows in, the soot and dust contained in the exhaust gas are removed, and the analysis work is performed to enable a more accurate analysis.

The filter unit 192 is connected to the collecting unit 191 to filter the collected exhaust gas. The filter unit 192 includes a mesh unit 1921 and a housing unit 1923. Hereinafter, description will be made with reference to FIG.

The mesh portion 1921 is formed of a porous material to filter out foreign matter of the exhaust gas. The mesh portion 1921 may be formed in a pipe shape having a path formed inside. As shown in FIG. 57, the mesh portion 1921 is formed by rolling a porous plate material on which a plurality of microvoids are formed, and forming a cross-section on the inside, May be preferable. In this case, the inner surface of the mesh portion 1921 contracts relatively and the outer surface thereof can expand relatively, so that the soot and the like caught by the mesh portion 1921 are mostly caught by the inner surface of the mesh portion 1921 do. Therefore, the gas spraying unit 195, which will be described later, injects a high-pressure gas toward the inner side of the mesh unit 1921 to effectively remove soot or the like adsorbed on the inner surface of the mesh unit 1921 from the mesh unit 1921 .

The housing part 1923 may be configured to surround the mesh part 1921 and preferably have a shape complementary to the shape of the mesh part 1921. 57, when the mesh portion 1921 is formed in the form of a pipe having a path formed on the inner side thereof, the housing portion 1923 has a shape complementary to the outer shape of the pipe-shaped mesh portion 1921 And may be configured to surround the outer circumferential surface of the mesh portion 1921 while forming an inner hollow space of a cylindrical shape.

The filter unit 192 is connected to the collecting unit 191 to filter the collected exhaust gas and then to a pipe through which the exhaust gas flows. The particulate matter of the exhaust gas collected through the collecting unit 191 It is preferable that the filter unit 192 is connected to the collecting unit 191 so that the collected exhaust gas is totally introduced through one end of the path.

As a result, all the collected exhaust gas passes through the mesh portion 1921 and flows into the pipe through which the exhaust gas flows, so that only the exhaust gas from which particulate matter has been removed can be analyzed. The pipe through which the exhaust gas flows can be connected to the filter unit 192 at one end thereof with a flow path of the filtered exhaust gas. In this case, the exhaust gas from which particulate matter has been removed has a moisture content of about 90%. In order to prevent CO 2, SO 2 contained in the exhaust gas from bonding with other substances, It is necessary to remove the moisture contained in the exhaust gas. For this purpose, the outer circumferential surface of the pipe may be wound with a coil or the like to maintain a temperature of about 140 ° C to 150 ° C. Finally, the dried exhaust gas containing a substance such as CO2 and SO2 is supplied to the analysis unit 194, which will be described later, through the heated pipe. On this piping, a pump 193 is included.

The pump 193 is installed on a pipe through which exhaust gas flows to drop the pressure in the pipe to collect the exhaust gas and allow the collected exhaust gas to flow into the analyzing unit 194. [ The present invention is not limited to the specific concept of the pump 193 and may be variously configured as long as the filtered exhaust gas can be easily moved to the analyzing unit 194 described below have.

A second valve 1931 may be formed on the front side of the pump 193. As will be described later, the gas injecting section 195 injects the high-pressure gas in a direction opposite to the direction in which the collected exhaust gas is filtered. When the movement of the exhaust gas and the injection of the high-pressure gas are simultaneously performed, The efficiency of removing the particulate matter adhered to the portion 1921 may deteriorate. Therefore, in a situation where the gas injection portion 195 is injected, the operation of sending the exhaust gas to the analysis portion 194 needs to be stopped. The second valve 1931 may be disposed on the front side of the pump 193 to lock the second valve 1931 when the gas injection unit 195 is operated. A more detailed description thereof will be discussed again in the process of explaining the control unit 197, which will be described later.

The analyzer 194 indicates a configuration for analyzing the filtered exhaust gas. The analyzer 194 is connected to the filter unit 192 through a pipe to receive dry exhaust gas filtered particulate matter. With respect to the configuration of the analyzer 194, this is not limited to any particular concept, and a known or known technique capable of analyzing the filtered exhaust gas component may be applied.

The gas injection unit 195 is connected to the filter unit 192 and communicates with the inner side of the filter unit 192 when the filter unit 192 detects an abnormality of the filter unit 192 to supply the gas along the inner side of the filter unit 192, And removing the foreign matter adhering to the surface. As described above, the exhaust gas collected through the collecting part 191 enters through the one end of the mesh part 1921 and passes through the space of the mesh part 1921 to the outside of the mesh part 1921 So that the relatively large particulate matter can be prevented from escaping from the gap of the mesh portion 1921.

Referring to FIG. 58, as the use of the filter unit 192 is repeated, a large amount of particulate matter is attached to the mesh unit 1921. If the voids of the mesh portion 1921 are clogged by these particulate materials, the amount of exhaust gas passing through the mesh portion 1921 is reduced, and the overall analysis efficiency of the monitoring device 19 is lowered. Accordingly, when it is determined that the amount of the particulate matter trapped in the mesh portion 1921 is large, the particulate matter is sprayed at a high pressure by operating the gas spraying portion 195 as shown in FIG. 59, So that it can be separated from the mesh portion 1921. In order to enhance this effect, it is preferable that the gas injecting section 195 injects the gas in a direction opposite to the direction in which the exhaust gas collected through the collecting section 191 is filtered.

Since the exhaust gas containing particulate matter enters through the one end of the mesh portion 1921, the particulate matter is preferably adhered to the inside of the mesh portion 1921, which is formed in a pipe shape. , It is preferable that the gas injecting unit 195 injects gas from the other end of the path to the path of the filter unit 192.

When the high-pressure gas is injected in the direction opposite to the direction in which the exhaust gas containing the particulate matter is filtered through the gas injecting unit 195, the particulate matter caught in the mesh unit 1921 is injected into the high- And can enter the exhaust gas processing apparatus 1 through the collecting unit 191. [0157]

The gas sprayed at the high pressure through the gas spraying unit 195 can be manually sprayed through the direct control of the operator. However, since the monitoring apparatus 19 is installed at a high place, It is preferable to be sprayed automatically because of exposure to danger. The sensing unit 196 and the control unit 197 may be configured to automatically inject the gas spraying unit 195.

The sensing unit 196 senses an abnormality of the filter unit 192. The sensing unit 196 preferably senses an abnormality of the filter unit 192 through a pressure abnormality . When the exhaust gas from which the particulate matter is removed on the pipe flows, the pressure in the pipe becomes higher than when the exhaust gas from which the particulate matter is removed does not flow. On the other hand, if a large amount of particulate matter is trapped on the voids of the mesh portion 1921, the pressure in the pipe is lowered through the pump 193, but the exhaust gas does not flow, so that the pressure in the pipe is continuously lowered.

The sensing unit 196 senses an abnormal condition such as a continuous pressure drop even when the pressure inside the pipe is dropped through the pump 193 so that the gap of the mesh unit 1921 is excessively blocked, I can recognize the problem. The sensing unit 196 generates an operation signal for operating the gas injection unit 195 when the pressure in the apparatus is lower than a set pressure. The operation signal is transmitted to the control unit 197, which will be described later, and can be regarded as a signal indicating the valve control system of the control unit 197. When an abnormality in the piping is confirmed through the gas injection unit 195, an operation signal is generated and sent to the control unit 197, and the control unit 197 opens or closes the valve according to the operation signal.

According to the above description, the sensing unit 196 may be connected to a pipe through which the exhaust gas flows to measure the pressure in the pipe, connect the sensing unit 196 to the filter unit 192, But it is also conceivable as a concept including all known or known configurations which can make a judgment that the air gap of the portion 1921 is excessively clogged and the filter portion 192 should be cleaned.

The sensing unit 196 may be connected to a controller 197 to transmit a result of determining whether the filter unit 192 needs to be cleaned to the controller 197.

The control unit 197 is connected to the sensing unit 196 to command the operation of the gas injection unit 195 when the pressure in the pipe is lower than the predetermined pressure. When the pressure in the pipe is lowered through the pump 193, as the exhaust gas from which the particulate matter having passed through the collecting unit 191 and the filter unit 192 is removed enters the pipe Predicted pressure in piping. When the filter unit 192 is in a steady state, the exhaust gas is introduced into the pipe through the filter unit 192 to increase the pressure in the pipe. The mesh unit 1921 of the filter unit 192, The amount of the exhaust gas entering the piping is reduced and the pressure in the piping becomes lower than the set pressure. At this time, the control unit 197 commands the gas injection unit 195 to operate.

The control command of the control unit 197 is a command to open or close the first valve 1951 formed at the gas output end of the gas injection unit 195 or to open or close the second valve 1931 formed at the front side of the pump 193 .

The control unit 197 opens the first valve 1951 in response to the operation signal generated through the sensing unit 196. In this case, The high pressure gas is injected toward the filter unit 192.

When the pressure of the pipe is not lower than the set pressure, the control unit 197 closes the first valve 1951, and there is no high-pressure gas injection through the gas injection unit 195 in this case.

When the pressure of the piping is lower than the set pressure and the gas injection through the gas injection unit 195 is performed, the direction of gas injection is opposite to the direction in which the collected exhaust gas is filtered. In this case, It is preferable to stop the operation to send the data to the analysis unit 194.

58 and 59, when the control unit 197 opens the first valve 1951, the second valve 1931 formed on the front side of the pump 193 is closed, Lt; / RTI > On the other hand, when the controller 197 does not open the first valve 1951, the second valve 1931 is opened and the collected exhaust gas is sent to the analyzer 194.

60 is a diagram illustrating a monitoring apparatus for a sulfur oxide removal apparatus of a ship having an automatic purging function according to another embodiment of the present invention. The embodiment of FIG. 60 is different from the embodiment of FIG. 56 in that the configuration of the preprocessor 198 is added to the front of the analyzer 194. In order to avoid duplication, the pre-processing unit 198 will be described below.

The preprocessing unit 198 is installed in front of the analyzing unit 194 to pre-process the exhaust gas. The exhaust gas heated while passing through the piping is dried to some extent to remove moisture. However, for more accurate analysis, it is necessary to completely remove the water contained in the exhaust gas.

Therefore, it is preferable that the pre-processing unit 198 includes all of processing the exhaust gas once before reaching the analyzing unit 194 to enhance the accuracy of the analysis.

61 is a flowchart showing an auto purging process of the monitoring apparatus. 61, the automatic purging process of the monitoring device 19 includes a collecting step S191, a filtering step S192, a sensing step S193, a controlling step S194, a preprocessing step S195, Step S196.

The collecting step S191 collects a part of the exhaust gas to be discharged through the collecting part 191. [ The trapping portion 191 is coupled to a gas outlet of the exhaust gas processing apparatus 1 through which the exhaust gas is discharged into the atmosphere and collects a part of the exhaust gas immediately before discharge to the filter portion 192 .

The filtering step S192 is a process of removing soot, dust, and the like contained in the exhaust gas by passing the exhaust gas collected through the collecting step S191 to the mesh portion 1921 having a plurality of voids formed thereon . The exhaust gas that has undergone the filtering step S192 is in a state in which soot, dust, and the like are removed, so that the accuracy of exhaust gas analysis can be improved.

The sensing step S193 is a step of detecting an abnormal condition in which the pressure is continuously lowered even if the pressure in the pipe is dropped through the pump 193. A pump 193 for allowing the collected exhaust gas to flow into the analyzing unit 194 by dropping the pressure in the pipe is formed on the pipe through which the exhaust gas flows. When the exhaust gas from which particulate matter is removed on the pipe flows, The pressure in the piping is higher than when the exhaust gas from which the particulate matter is removed does not flow. However, when a large amount of particulate matter is trapped on the voids of the mesh portion 1921, the pressure in the pipe is lowered through the pump 193, but the exhaust gas does not flow, so that the pressure in the pipe is continuously lowered. Accordingly, it is possible to recognize a situation in which the excessive amount of soot is stuck on the mesh portion 1921. If the normal state is detected through the sensing step S193, the process may proceed to the preprocessing step S195, which will be described later. If the abnormal state is detected through the sensing step S193, the control step S194 Can proceed.

The control step S194 is a step of controlling the first valve 1951 and the second valve 1931 so that gas is injected when an abnormal condition is detected through the sensing step S193. 62, the control step S194 includes a second valve closing step S1941, a first valve opening step S1943, a first valve closing step S1945, a second valve opening step S1947).

When the pressure inside the piping is lower than the set pressure, the second valve closing step S1941 closes the second valve 1931 so that no more exhaust gas flows into the analyzing part 194. Then, by opening the first valve 1951 through the first valve opening step S1943, a high-pressure gas can be injected toward the filter unit 192, and then, in the first valve closing step S1945, The high pressure gas injection is stopped by closing the first valve 1951 through the second valve opening step S1947 and opening the second valve 1931 through the second valve opening step S1947, And the exhaust gas flows into the analyzer 194.

The preprocessing step S195 is a step of increasing the accuracy of the exhaust gas analysis by processing the exhaust gas through the pre-processing unit 198 provided in front of the analyzing unit 194 and pre-processing the exhaust gas. That is, the preprocessing step (S195) may be regarded as a step collectively referring to all processes of processing the filtered exhaust gas to improve the accuracy of analysis of the exhaust gas. This pre-processing step S195 may be omitted and does not exclude the embodiment in which the filtered exhaust gas flows directly into the analysis step S196, which will be described later, without the preprocessing step S195.

The analysis step S196 is a step of analyzing the filtered exhaust gas. The filtered particulate matter-containing exhaust gas is supplied to the analyzing part 194, so that the exhaust gas discharged to the atmosphere through the exhaust gas processing device is harmful It is possible to confirm that the substance has been removed in accordance with the standard.
