Description

FIELD OF THE INVENTION The present invention relates to a system and a method for purifying combustion gases containing incomplete combustion compounds and fine dusts,

The present invention prevents various kinds of incomplete combustion compounds that are not completely combusted due to lack of oxygen in the combustion gas generated in the combustion process from the discharge process of the combustion gas or neutralize the toxicity, thereby preventing environmental pollution caused by the combustion gas And more particularly, to a system and method for purifying combustion gases including incomplete combustion compounds and fine dust that can clean incomplete combustibles left in the system after removal of incomplete combustion compounds.

Currently, a large amount of household waste, general industrial waste, or industrial waste is generated due to population growth and industrial development. Such garbage or waste is a major cause of environmental pollution in recent years, and as social problems, .

Conventionally, methods of disposal such as landfill, regeneration, and incineration are known as methods for treating such refuse and industrial waste.

As the landfill method is a pre-modern method, the limit due to the absolute shortage of landfill is gradually increasing, and the problem of soil pollution due to indiscriminate landfill of undissolved wastes is a big problem, and a considerable cost is incurred in landfill. Is emerging.

Therefore, it is advantageous to treat waste or waste in an incinerating manner rather than a landfill method, and recent technology has an advantage that waste heat generated in incineration can be effectively recycled while reducing the amount of incineration combustible.

Furthermore, in the incineration method of known waste or refuse, a dust collecting device is installed on one side of the incinerator constructed with refractory material, and waste or waste is ignited / burned by using burner or gas torch, And the combustion gas generated at this time is subjected to dust collection and discharged to the atmosphere.

However, since most of incinerators in general operate fossil fuel or natural gas as a heat source, the combustion temperature is relatively low at 1,000 ° C. or less, and the incombustibility is high, and nonflammable waste having high flammability or melting point can not be incinerated properly.

Therefore, in order to overcome the limitations of these incineration facilities, the following equipments are disclosed.

Korean Patent No. 10-1138693 discloses a combustion gas treating apparatus and an incineration system including the same, wherein the incinerator is re-combusted through a whirlwind (tornado) swirl generated during operation of various types of incinerators, Thereby enabling effective removal of toxic substances, thereby providing an environmentally friendly incineration environment. However, in the prior art, there is a fear that the toxic substances are not mixed properly even when heated, as the toxic substances are mixed again, and there is a possibility that certain substances may remain in the inside due to the occurrence of the whirlwind have.

As another prior art, Korean Patent Registration No. 10-0836182 'Waste Heat Treatment System' is a system for cutting waste to a predetermined size or smaller so as to quickly heat the waste and grinding and drying the waste to preheat the waste, Heat treatment process for decomposing and collecting harmful gases generated during low temperature heat treatment process, wet cleaning process for collecting fine dust, incomplete burning process during low temperature heat treatment process, and high temperature heat source for untreated harmful gas in the wet cleaning process stage And a dry purifying process for re-purifying. During the low-temperature heat treatment process, the waste is separated and recovered in a recyclable solid state. For this purpose, a heat source is placed in a low-temperature heat treatment chamber and a gradient is applied to the heat source in a stepwise manner, thereby varying the degree of decomposition and conditions of the organic waste. By using a conveyor system to sequentially pass a heat source, The separated state is collected in a recyclable solid state, and the inorganic waste is collected in the final stage.

During the wet cleaning process, the harmful gas is subjected to the first purification treatment. For this purpose, the gaseous dust generated by the decomposition of the waste in the low-temperature heat treatment chamber and the gaseous dust influenced by the passing gravity are collected in the washing water, and when gas is generated from the settled gaseous dust, The harmful gas generated from the heat treatment chamber and the ultrafine dust are introduced into the dry purification process, and finally the ultimate dust and the untreated dust are purified. For this purpose, a high-temperature heat source is provided to remove superfine dust, and the gas is reacted with the ceramic porous body or the ceramic powder to generate a secondary product.

As described above, according to the present invention, if the heat source is graded step by step, it is possible to suppress the generation of carbon dioxide by causing carbon to bind with oxygen in the decomposition process of the waste as much as possible, and to prevent air pollution. In addition, waste collected in a solid state can be recycled as a liquid or gaseous energy source, and has a structure in which only the purified gas is discharged through a wet and dry purification process.

However, such a structure is subjected to purification at least twice during the purification process. As the process proceeds, there is a disadvantage in maintenance because there is no way to store or remove the treatments generated in each process.

Therefore, it is possible to prevent the environmental pollution caused by the combustion gas by eliminating various kinds of incomplete combustion compounds which are not completely combusted due to lack of oxygen in the combustion gas generated in the combustion process, or by neutralizing the toxicity Furthermore, there is a need to develop an incomplete combustion compound removal system that can clean the incomplete combustibles left in the system after removal of incomplete combustion compounds.

In addition, by neutralizing the toxic substances generated in the combustion process, environmental pollution due to combustion gas can be prevented.

Furthermore, it provides a structure that can clean the soot, the incomplete combustible material left in the system after the incomplete combustion compound removal operation.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

FIG. 1 is a cross-sectional view showing the basic structure of the purifying system of the present invention, FIG. 2 is a sectional view showing the cleaning structure of the purifying system of the present invention, Fig.

1 to 3, the incomplete combustion compound removal system of the present invention includes a first pipe 100 having a hollow 110 into which a combustion gas containing an incomplete combustion compound flows, a first pipe 100 A second pipe 500 for exhausting the combustion gas moved along the first pipe 100 to the outside, and a second pipe 500 for discharging the flue gas moved along the first pipe 100 to the outside, .

 At this time, preferably, the combined shape of the first tube 100 and the second tube 500 may have a T shape.

Here, the incomplete combustion compound is based on N (nitrogen), S (sulfur), C (carbon), etc. When heat is applied to general fuel or natural material, It can be burned with complete burning to achieve the desired incineration pattern. However, when oxygen is insufficient or insufficient heat is not applied, there is not enough oxygen to react or a proper reaction does not occur and unstable substances such as CO (carbon monoxide) and NO (nitrogen monoxide) are generated. can do. Furthermore, there are cases where C, N, and S are left as such, especially these are the components of whites or black smoke that arise when we burn a substance. Most of the components of these fumes are the incomplete combustion compounds described above.

Most of these smoke components are harmful to humans and the environment, and the efficiency of combustion is gradually lowered, so that more incomplete combustion compound outflows are likely to occur. Therefore, the purification of the combustion gas is performed by filtering out these incomplete combustion compounds or discharging them to the outside.

However, since it is difficult to remove the incomplete combustion compound in the combustion gas by simply providing the first and second tubes 100 and 500, the first tube 100 may have various configurations on the inner circumferential surface of the first tube 100, The representative structure is the reaction rod assembly 200.

The reaction rod assembly 200 has an antenna structure in which a plurality of reaction rods 210 are coupled in a multistage manner such that the reaction rods 210 can be drawn out and drawn in. ) To burn the incomplete combustion compound to generate soot.

At this time, in the case of the reaction rod assembly 200, the wire connected to one side of the inside of the reaction rod 210 located at the outermost position (preferably a material such as metal, rubber, synthetic resin, etc., (Not shown) including a reel for winding the wire, a shaft for rotatably fixing the reel, and a motor for providing a rotational force to the reel, The wire can be wound or unwound while the reel is rotated through the driving unit to automatically control the withdrawal and withdrawal of the reaction rod 210.

With this configuration, it is possible to reduce incomplete combustion compounds in the combustion gas by burning incomplete combustion compounds to generate soot, but the problem is soot. Such soot accumulates on the surface of the reaction rod 210 or the inner circumferential surface of the first pipe 100. If the soot accumulates excessively, heat transfer through the heater 300 becomes difficult and the efficiency of the incomplete combustion compound purification is gradually reduced.

Therefore, the soot should be cleaned frequently, and the water washing apparatus 400 can be used at this time.

The water washing apparatus 400 includes a tank 410 for storing washing liquid such as water and a washing liquid, a pipe 422 for supplying the washing liquid to the tank 410 and extending to a predetermined length, And a nozzle 423 is provided at an end of the pipe 422 to feed the nozzle 430 into the hollow 110 or to the inlet of the hollow 110 Needless to say, the washing liquid can be sprayed in the state of Dan.

At this time, the soot can be washed out through the cleaning force of the cleaning liquid itself and the pressure generated by the discharge through the nozzle 430. At this time, it is possible to clean the soot generated on the surface of the reaction rod assembly 200 by spraying water with the reaction rod assembly 200 being drawn out to the maximum, and the reaction rod assembly 200 And the reaction rod 210 itself receives the washing solution at various positions, so that the soot can be easily washed away.

In this case, the water washing apparatus 400 is not always required to be located in the hollow 110 of the first pipe 100, and a cradle that can be mounted or stored on one side of the purification system is provided, The nozzle 430 can be moved and used only when the nozzle 430 is moved. Also, as shown in the drawing, a separate connection pipe for connecting the first pipe 100 and the second pipe 500 may be provided and the water purifying device 400 may be configured to flow through the connection pipe. to be.

Further, in addition to the robot arm, the structure of the water washing apparatus 400 having a separate power unit configuration may be applied. Although not shown in the drawing, the tank 410 and the pump 421, which store water in the water washing apparatus 400 instead of the robot arm, are used as they are, and a bellows type pipe 422 and further drives the nozzle 430 with a driving device such as a wheel. Further, a magnetic body may be attached to the wheel so that the wheels of the nozzle 430 can move along the inner circumferential surface of the first tube 100 or the second tube 500, or a rail that can be moved by coupling the wheels to the inner circumferential surface of each tube The nozzle 430 may be moved along the rail by a predetermined distance. In this case, it is needless to say that the rail is preferably formed in a spiral shape along the inner circumferential surface of each tube, and can have a structure capable of spraying water at various positions.

Further, it is assumed that the first pipe 100 and the second pipe 500 extending in a T-shape can be located at the outlet of the first pipe 100, May be provided. That is, the second valve 520, which is a valve located on the upper side of the second pipe 500, passes through the reaction rod assembly 200 to burn the incomplete combustion compound, The first valve 510, which is a valve located on the lower side of the pipe 500, is connected to a dust collecting part 600 that stores soot generated through washing or other washing through the water washing device 400.

Here, the dust collecting unit 600 stores the soot and then performs a storage function of discarding the soot.

Finally, the controller 990 may be configured to sequentially close or open the valves located in the second pipe 500 as described above when sensing the driving of the heater 300 or the water washing apparatus 400. [

When such configurations are provided, a mobile washing apparatus 800 may be further included, which is a configuration related to soot cleaning, which is a method by which the efficiency of the reaction rod assembly 200 and the heater 300 can be further increased.

The mobile washing apparatus 800 includes a piston 810 having a diameter corresponding to the hollow 110 of the first tube 100 and a driving unit 820 for drawing and pulling the piston 810, Here, the driving unit 820 is provided on one side of the piston 810 such as a motor, a shaft, or a cylinder, and can reciprocate the piston 810 forward and backward. In the case of the piston 810 in the mobile cleaner 800, a cylindrical portion as shown in the figure means a portion of the piston 810 having protrusions or fur on its surface so that the outer peripheral surface of the piston 810 is hollow It is also possible to provide a structure that can remove the soot more easily when the stacked soot is removed.

In other words, the soot remaining on the inner peripheral surface of the hollow 110 can be removed through the reciprocating motion of the piston 810.

Furthermore, such a problem in soot removal can occur during the insertion and extraction of the piston 810, which is directly caused by the influence of the pressure. For example, when the syringe piston 810 is pushed or pulled while the syringe outlet is closed, the piston 810 of the syringe 840 is hard to move easily due to the internal pressure. Therefore, the piston 810 of the movable cleaning device 800 can not easily move in the hollow 110 due to a similar phenomenon. To assist this movement, And a feedback tube 530 connecting the periphery of the inlet of the first tube 100 to the second tube 100.

In addition, since the feedback tube 530 does not need to be always open, a check valve 531 may be provided on one side of the feedback tube 530 so that it can be used only when necessary.

Accordingly, when the piston 810 is reciprocated while being in contact with the inner circumferential surface of the hollow 110, the piston 810 can be freely moved when the remaining soot is removed from the inner circumferential surface of the hollow 110, The controller 990 controls the internal pressure of the movable cleaner 800 so that the opening and closing control of the check valve 531 can be automatically performed when the movable cleaner 800 is operated. It is needless to say that a module may be provided.

FIG. 4 is a cross-sectional view illustrating application of an expanded exhaust configuration to a purge system of the present invention. FIG.

First, the configuration related to the discharge will be described. First, heat is applied to the combustion gas through the heater 300, and the gas from which the incomplete combustion compound is removed is discharged to the outside through the second pipe 500. The problem here is that substances such as carbon dioxide are included in the removal process of incomplete combustion compounds to a greater extent than the normal atmosphere. Such a substance is a by-product of purification, and it is needless to say that it is possible to reduce adverse effects on the external environment of discharging the purified by-product after lowering it to a level similar to that of the external atmosphere.

The function of lowering the purification by-product to a level similar to that of the external atmosphere is called the discharge assisting device 900. Referring to the configuration of the discharge assisting device 900, first, in the second pipe 500, A storage section 910 for storing the combustion gas discharged from the first pipe 100 and a storage opening / closing valve 920 for opening / closing the storage section 910 are provided at a position facing the outlet side of the storage section 100, .

That is, a part of the combustion gas discharged through the first pipe 100 can be discharged directly through the second pipe 500, while the other part is configured to move toward the storage part 910. In this case, the storage unit 910 is provided with an air injection unit 930 for injecting outside air into the storage unit 910 and mixing the combustion air with the combustion gas, so that the combustion gas can have a similar structure to that of the outside atmosphere.

Further, the exhaust unit 940 may serve to discharge the combustion gas mixed with the outside air to the one side of the second pipe 500 through the structure described above. It is needless to say that this structure allows more effective purification.

Here, a separate pipe for connecting the second pipe 500 and the storage unit 910 may be further provided. The pipe may include an air quality analyzer, which is a kind of sensor for analyzing the components of the introduced gas, a separate air inlet and a temperature And an intake fan 952 for assisting the inflow of the gas may be further provided. In addition, a plurality of water injectors 953 for removing impurities such as fine dust by spraying water vapor may be provided in the inside of the pipe, and further, as shown in the drawing, a separate branch 954 And a separate structure for allowing water, fine dust, and purified gas to flow through the cylindrical screw 956 located at the lower end of the branch 954 can be further provided. (It goes without saying that residual gas and water can be discharged through a separate water outlet (not shown) when the inflow amount of this branch 954 is excessive.) At this time, The same impurity will be able to hang once more.

5 is a cross-sectional view showing another embodiment of the extended discharge configuration applied to the second pipe.

In addition, a configuration may be employed in which residual impurities such as fine dust contained in the combustion gas passing through the second pipe 500 are filtered again. That is, as shown in the drawing, it is also possible to consider a configuration in which a plant (958) or a vegetation (958) such as a plant is placed separately to reduce carbon dioxide through respiration of the vegetation (958) or a configuration in which carbon dioxide is removed through additional chemical treatment Of course. Of course, in order to utilize such a vegetation 958, the temperature of the gas should be lowered to a temperature level similar to room temperature through a configuration such as an air inlet 930 and a temperature controller (not shown).

This will be described in more detail as follows.

First, a separate discharge pipe 960 extending from the portion where the combustion gas is to be discharged in the second pipe 500 and extending in the form of W may be further included.

A plurality of water injectors 953 may be provided in the discharge pipe 960 at predetermined intervals, so that water is sprayed to the moving combustion gas through the water injector 953, And the temperature of the combustion gas can be sufficiently lowered.

At this time, in the case of the shape of the discharge pipe 960, a w-shaped w-shaped as shown in the drawing is general, but a shape like a spring may be applied according to circumstances. The liquid injected through the water injector 953 and the residual impurities contained in the combustion gas are mixed in the lower end of the discharge pipe 960. As shown in the figure, And a branch 954 capable of discharging the flue gas to the outside. In other words, the discharge pipe 960 may be formed in the shape of W as shown in the figure. Also, as shown in the drawing, a multiple connection structure with the branch 954 may be formed so as to include impurities such as fine dust through the branch 954 It is of course possible to provide a structure capable of discharging the liquid and the combustion gas. That is, the discharge pipe 960 does not discharge the combustion gas directly to the outside, but collects the combustion gas in the discharge pipe 960 and moves it to the water tank 957 together with the liquid containing the impurities. It is necessary to be capable of collecting a certain level of combustion gas and spraying water to filter out impurities such as fine dust. The combustion gas may be excessively introduced into the discharge pipe 960 and flow backward or may be excessively loaded to the discharge pipe 960. [ It is of course possible to prevent the user from being added.

The branch 954 preferably further includes a valve positioned between the discharge tube 960 and the cylindrical screw 956 and capable of being selectively locked and opened. Further, the branch 954 may include a separate fine dust Sensor, residual impurity sensor, and the like, and it is of course possible to control the opening and closing of the valve according to the numerical value of the fine dust or other residual impurities detected by the sensor.

When the valve is opened, the liquid and the combustion gas containing the fine dust and residual impurities can move to the water tank 957 while passing through the cylindrical screw 956. The cylindrical screw 956 can rotate and adjust the flow rate and pressure so that it can be effectively utilized to move the liquid and the combustion gas from the discharge pipe 960 to the water tank 957. Accordingly, the liquid mixed with the fine dust and the residual impurities is mixed in the water in the water tank 957, and the combustion gas passes through the water and moves to the separate purification zone 955 where the wood (vegetation) 958 is located At this time, a separate water purifier 959 may be provided in the water tank 957. This water purifier 959 may further be used for adjusting the water level of the water tank 957, Of course, the tank 957 can also be configured to have a detachable structure to remove or clean excess fine dust or impurities when they are accumulated.

In the purification zone 955, the vegetation 958 serves to lower the concentration of CO ₂ contained in the combustion gas to a level similar to that of the outside, which utilizes the breathing process of the plant. However, this vegetation (958) can not inhale excessively CO ₂ , and in particular, the temperature must be lowered so that the vegetation (958) can survive. Therefore, in order to achieve a CO ₂ concentration and a temperature in a viable range, (Inflow volume control, dilution through inflow air, temperature drop through water injection, etc.) are essential. Therefore, the air injector 930 and the water injector 953 are used to increase the efficiency of the control section.

That is, the outside air is mixed with the combustion gas in advance at a predetermined rate through the air inlet 930 to prevent excessive CO ₂ from flowing into the purification zone 955, so that the combustion gas can be sufficiently purified. Further, 953) so that the temperature of the combustion gas is lowered.

When the combustion gas flows into the purifying zone 955 through the above process, the purifying zone 955 can utilize the various vegetation 958 as a configuration capable of finally filtering the remaining material that may remain even after passing through the foregoing configuration And finally, purge the exhaust gas through the last exhaust port.

6 is a cross-sectional view showing one embodiment in which the flow control valve 120 is applied to the purifying system of the present invention.

Furthermore, the hollow 110 of the first pipe 100 may be provided with a flow control valve 120 for opening and closing the inlet and the outlet, or one side of the hollow 110. Here, the flow rate control valve 120 is configured to block or open the hollow 110, and can be manually and automatically controlled to open and close by a separate operation switch or drive configuration. Here, the necessity of the flow control valve 120 is as follows.

First, the combustion gas flows at a constant speed. Usually, the combustion gas flowing in the purification system has a speed of about 30 m per minute. Such a speed may be a somewhat difficult speed to evenly transfer the heat of the reaction rod assembly 200 to all the combustion gases when the length of the first pipe 100 is short. Accordingly, the flow of the combustion gas through the flow control valve 120 is intermittently maintained for a predetermined period of time, thereby providing a time for the heater 300 to uniformly supply heat to the combustion gas, thereby inducing the soot generation reaction to occur more actively .

Of course, the controller 990 is also provided with a flow rate control module for repeatedly controlling the opening and closing of the flow rate control valve 120 at every predetermined time to perform more accurate purification work of the incomplete combustion compound through the opening / closing control of the flow rate control valve 120 Of course.

7 is a cross-sectional view showing one embodiment of the reaction rod assembly 200. As shown in FIG.

Further, various embodiments utilizing the reaction rod assembly 200 will be described as follows.

Examples of a general incomplete combustion compound include NO ₂ (nitrogen dioxide) and NO (nitrogen monoxide) in the case of a nitrogen compound. Since they are highly toxic, they may adversely affect the environment and require purification work.

However, in the case of such a nitrogen compound, it is possible to remove the toxicity through the reaction in the molecular unit without applying heat, which is the electric discharge.

E.g,

It is possible to remove oxygen from the nitrogen oxide, and finally, it can be confirmed that it can be divided into harmless nitrogen and oxygen.

In this configuration, the reaction rod assembly 200 is exposed to the outside from the nodal unit 220 having an electrically conductive material, and is electrically connected to the external power source, And a discharge electrode 240 for discharging electric field energy by applying a voltage to the combustion gas located therein. In addition, when two or more discharge electrodes 240 are present, it is needless to say that the above-described ion bonding can be performed by utilizing electric discharge (spark) generated between the discharge electrodes 240.

That is, this spark generation plays the same role as supplying electrons to the combustion gas, and it is possible to spread the electrons at a higher speed and a wider range than the case of simply transmitting heat through the heater 300, Of course, a faster and more reliable response can be expected. However, it is needless to say that in order to accelerate the reaction of the electrons in this case, it is needless to say that the structure of the first tube 100 having the inner wall capable of providing a certain temperature and being able to withstand spark generation must be provided.

In addition, as a configuration that further utilizes such a discharge electrode 240, a charging electrode (not shown) that is electrically charged by discharge corresponding to the discharge electrode 240 can be selectively provided. When such a charging electrode is prepared, It is possible to utilize the generated static electricity to collect soot or reactant remaining after the reaction. In this case, the first tube 100 is divided into two, and the front part of the reaction rod assembly 200 having the heater 300 is positioned to form a heat section, and the rear part of the reaction rod assembly 200 having the discharge electrode 240 200) is used as a discharge section (electrostatic section) (this is a method that can be selected when the discharge configuration can not withstand the heater 300).

Particularly, combustion gases may include incomplete combustion compounds having large particles that are visibly large, so that the use of such static electricity can serve to prevent incomplete combustion compounds having large particles from moving along the combustion gas.

8 is a cross-sectional view showing another embodiment of the reaction rod assembly 200.

In addition, in order to further increase the effect of the discharge electrode 240, it is necessary to increase the initial contact area. A discharge net 251 extending from the discharge electrode 240 to the inner side of the hollow 110 as a conductive material is formed on the end of the nod 220 located at the outermost side of the reaction rod 210, And a ring shaped net frame 252 extending along the periphery of the discharge net 251 and fixing the discharge net 251 in a fixed manner.

This is similar to an electronic mosquito bike, and unlike an electronic mosquito bike, a high-voltage power source is used to generate a discharge, and since the contact area with the combustion gas is increased, And it is also possible to use ion-bonding with positive ion of a large incomplete combustion compound directly contacting the discharge net 251.

9 is a cross-sectional view showing a further embodiment of the reaction rod assembly 200.

Further, a method of chemically treating such an incomplete combustion compound may be considered. That is, a kind of neutralization reaction is utilized. An example will be described as follows.

First, it is assumed that sulfur is contained in the fuel and SO ₂ is generated during combustion. At this time, if the solution containing CaO is vaporized and sprinkled, the SO ₂ reacts with CaO to be crystallized by CaSO ₄ , so that only oxygen can be discharged.

If such a neutralization reaction is utilized, substances which are not desirable to be contained in the air such as sulfur are crystallized through the neutralization reaction and are separated from the combustion gas, unlike the previous electrical reactions, which are mixed with air, It can be seen that the gas is purified and discharged with almost no hazardous substances.

In this configuration, the purifying system is provided with a gas tank 263 for storing a neutralizing gas neutralizing reaction with the combustion gas, and a gas tank 263 extending toward the inside of the nodal portion 220 located at the outermost side of the gas tank 263 A gas supply device 266 including a channel 264 for transporting neutralized gas through a pump provided in the gas tank 263 and a branch channel 265 branched at a predetermined interval in the channel 264 is provided And it can be seen that this is configurable if the gas tank 263 can be configured to be connected through the pipeline 264 without having to be close to the first pipe 100 as shown in the figure.

Since the types of neutralizing gases necessary for the neutralization reaction are different for each incomplete combustion compound, the gas tank 263 is preferably provided with a sufficient space for storing various gases, and a sufficient number of channels (264).

The reaction rod 210 is provided with a plurality of flow holes 261 passing through the nod 220 in a state of being connected to the branch conduit 265 and a plurality of nozzles 261 mounted on the end of the flow hole 261, The nozzle 262 may be formed to be buried in the flow hole 261 or may be configured to be capable of being drawn into and drawn out of the flow hole 261) to be.

If the solution containing CaO is not completely reacted, lime crystals may be left as a by-product. If the CaO-containing solution is solidified, the reaction rod assembly 200 may be prevented from being drawn out and drawn out while being crystallized. have. Therefore, it is possible to further include a ring-shaped passing body (not shown) having a size corresponding to the inner circumferential surface of the first tube 100 so that the lime can be scraped off separately during the cleaning, The lime crystals are solidified on the inner circumferential surface of the first tube 100 by removing the lime from the inner circumferential surface of the first tube 100 or scraping the crystallized lime before the lime is crystallized by passing through the tube 100 after passing through the tube 100, It is of course possible to prevent the operation of the rod assembly 200 from being restricted.

FIG. 10 is a conceptual diagram showing the group control of the reaction rod assembly 200.

Further, the reaction rod assembly 200 may be divided into three groups, rather than being driven in a single configuration, to form sequential driving by taking advantage of the characteristics of each group. That is, the reaction rod assembly 200 is provided with a heater 300 for generating heat at a first temperature. The reaction rod assembly 200 includes a first reaction rod group 221 drawn out to a first length, And a second reaction rod group 222 which is drawn out to a second length longer than the first length.

This group basically takes out the first reaction rod group 221 having a short length and the second reaction rod group 222 having a long length sequentially to heat the combustion gas to heat the combustion gas sequentially to other positions of the combustion gas So that uniform heat distribution can be maintained.

The controller 990 may include a temperature sensor for measuring the temperature of the hollow 110 on one side of the inner circumferential surface of the first tube 100. The controller 990 controls the temperature of the reaction rod 210 according to the temperature measured by the temperature sensor, And an input / output module for controlling the drawing-in and drawing-in. That is, it is possible to provide a structure in which heat can be more easily supplied into the combustion gas by controlling the degree of drawing of the first pipe 100 according to the increase or decrease in the ambient temperature.

When the combustion gas flows in the moving hole 260, the moving body 270 can be pushed away a certain distance along the inflow direction of the combustion gas. As shown in FIG. Therefore, it is possible to expand the deodorizing area while being pushed when the flue gas is introduced.

The moving body 270 further includes a through hole 271 penetrating the inside of the moving body 260 along the extension direction of the moving hole 260 and a mesh body 272 provided inside the through hole 271, And a deodorant 273 in the form of a powder or a granule is provided. Of course, the net 272 should be provided with an appropriate size hole so that the deodorant 273 does not flow out to the outside, and the net 272 may be separately provided at the entrance of the through hole 271 so that the net 272 does not easily escape from the through hole 271 Or a structure in which the inner diameter of the entrance portion is reduced or an adhesive is applied to the surface of the net 272 can be applied. In addition, when the moving body 270 slides, it may be provided with a separate stopper structure so as not to easily get out of the moving body 270. Particularly, when the reaction rod 210 is inserted after the sliding movement, A tapered surface tilted from the inner circumferential surface of the hollow 110 is formed at an end of the moving hole 260 which is exposed to the outside of the moving hole 260 when sliding in the moving hole 260, It is of course possible to have a structure capable of returning to the inside of the moving hole 260 naturally through the tapered surface upon entry.

This configuration may also be provided at the outlet side located after the purifying zone 955 of FIG. That is, it can be utilized as a structure capable of eliminating the odor before the exhaust gas finally passes through the reaction rod assembly 200 to which the moving body 270 equipped with the exhaust gas finally discharged through the exhaust port is applied Of course it is.

In the first step, the purge preparation step is performed in the second pipe 500 to the dust collecting part 600 side.

Next, in the heat reaction step, the heater 300 is driven in a state where the reaction rod 210 is drawn out, and the combustion gas is passed through the hollow 110 to generate soot.

Further, in the third washing step, the second valve 520 is closed, the first valve 510 is opened, and the washing liquid is sprayed to the hollow 110 through the water washing device 400 to remove the soot This is the washing process, in which the surface is cleaned in the final step of the fourth step as a more thorough washing of the soot.

In the surface cleaning step, the remaining sticky remains on the inner circumferential surface after the spraying of the cleaning liquid through the piston 810 of the movable cleaning device 800 having the piston 810 inserted into the hollow 110 with the reaction rod 210 pulled in. It is a scraping process. Thereafter, the soot and the washing liquid are collected in separate discharge ports or the dust collecting unit 600 so that they can be discharged later.
