The present invention relates to a system and a control method for reducing harmful substances of a vessel and a vessel using the same. More specifically, the present invention relates to a communication pipeline such as a hull operating controller in charge of the operation of the hull, an engine driver in charge of driving the engine, and the like.

The present invention relates to a system and a control method for reducing harmful substances of a ship provided and a ship using the same.

Recently, as regulations on harmful substances emitted from ships, such as nitrogen oxides (NO _x ), have been tightened (for reference, Tier III, which enters into force in 2016, has reduced emissions of nitrogen oxides, for example, below 3.4 g / KW (rpm 130 For example, various types of hazardous materials reduction equipment for ships using technologies such as SCR (Selective Catalyst Reduction) have been widely developed and distributed.

For example, Korean Patent Publication No. 10-2010-132310 (Name: SCR system for ships using urea powder and nitrogen oxide reduction method) (published December 17, 2010), Korean Patent Publication No. 10-2003-127737 ( Name: Blocking device of SCR device using waste heat of ship) (published Nov. 25, 2013), Korean Patent Publication No. 10-2014-46651 (name: denitrification apparatus of large engine for ship) (published Apr. 21, 2014) ) Discloses in more detail the detailed configuration of the ship's harmful material reduction apparatus according to the prior art.

On the other hand, as shown in Figure 1, the harmful substance reduction device 10, for example, the nitrogen oxide reduction device according to the prior art, the exhaust gas distribution line 12 withdrawn from the engine 11 side, Reducing agent storage tank 21 for storing a reducing agent (eg, urea) for reducing harmful substances, such as nitrogen oxides (NO _x ), and connected to the reducing agent storage tank 21, to the exhaust gas distribution line 12 Reducing agent injector 20 for injecting the reducing agent (for example, urea) stored in the reducing agent storage tank 21, and supplying compressed air to smoothly perform a series of reducing agent injection function on the reducing agent injector 20 side A controller 23 which controls the compressed air supply valve 24 by the reducing agent injector 20 by controlling the compressed air supply valve 24 and the compressed air supply valve 24 based on the measured values output from the sensors 19; The engine 11 and the exhaust gas distribution line 12 through While being connected, the SCR reactor 13 for passing the exhaust gas and the reducing agent together to purify harmful substances (eg, nitrogen oxides (NO _x )) included in the exhaust gas has a systematic combination.

(18) and the SCR chamber 17 containing this SCR catalyst 18 are combined.

Under such a conventional system, when the output amount of the engine 11 becomes large, the scale of the hazardous substance reducing device 10 will inevitably increase in proportion to it. This is because, when the output amount of the engine 11 becomes large, the amount of exhaust gas generated from the engine 11 side also inevitably increases.

However, in proportion to the output of the engine 11, there are bound to be a lot of limitations in inadvertently expanding the scale of the hazardous substance reducing device 10.

This can only happen.

Of course, under the above-mentioned limitations on the scale-up of the hazardous substance reducing device 10, the ship operating subject will have a great difficulty in purifying the hazardous substances generated from the engine 11 side, and, accordingly, You will have no choice but to take tangible and intangible damage.

Hereinafter, with reference to the accompanying drawings, embodiments of the present invention will be described in more detail by way of example.

As shown in FIG. 2, under a series of operating environments, the ship 300 side, according to the purpose of operation, not only the general sea area N, but also a discharge restriction area (ECA) where the emission of hazardous substances is strictly prohibited. Area is also frequently operated.

Under such an operating environment, in the present invention, when the ship 300 is located in the general maritime zone (N), the normal operating state (for example, the up operation state of the engine 303, the operation stop state of the harmful substance reduction device 100). Keep) appropriately. When the vessel 300 is located at the ECA or the ECA entry reserve points (Y1, Y2), the various output factors of the engine 303 so that the amount of exhaust gas discharged from the engine 303 is minimized Measures to adjust downward>, <preliminary heating of the hazardous substance reducing device 100 so that the harmful substance reducing device 100 can perform its function in a timely manner (that is, when the hull 300a enters the ECA). > Find additional backs. Through this, the hazardous substance reduction device 100 side, in advance to achieve a sufficient heating state capable of normal operation, and as soon as the ECA operation of the hull 300a is started, the minimum amount of exhaust gas (or the minimum amount of the engine 303 side) Engine (303) side of the hazardous materials only), to perform a series of harmful substances reduction function. Therefore, even when the scale of the hazardous substance reduction device 100 is not increased on the ship operator side (that is, even when the hazardous substance reduction device 100 is downsized), it is possible to flexibly respond to the recent regulation of hazardous substances. Make sure

For reference, in the related art, whether the ship 300 is located in the general maritime zone N or the ECA, the engine 303 normally operates the output unconditionally (ie, the engine side output factor is not selectively down-regulated). ). Therefore, the harmful substance reduction device 100 for reducing the harmful substances outputted from the engine 303 also has to maintain the enlarged scale at all times. As a result, the above-mentioned problems caused by the enlargement of the hazardous substance reducing device 100 on the ship operator side, for example, the problem of lowering the space utilization efficiency of the vessel 300, the problem of impossible to transport the large hazardous substance reducing device 100 on land Inevitably, they have to bear the problem of not being able to enlarge various valves.

As shown in Figure 3, the ship 300 according to the present invention includes a hull 300a, an engine 303 for propulsion of the hull 300a; Hazardous substance reduction device 100 for reducing the harmful substances contained in the exhaust gas discharged from the engine 303 has a configuration that is systematically combined.

In this case, the hazardous substance reducing device 100, for example, the nitrogen oxide reducing device is the exhaust gas distribution line 112 withdrawn from the engine 303 side of the harmful substances (for example, nitrogen oxides (NO _x )) Reductant storage tank 121 for storing a reducing agent (for example, urea) for reduction, and connected to the reducing agent storage tank 121, the reducing agent stored in the reducing agent storage tank 121 in the exhaust gas distribution line 112 It is output from the reducing agent injector 120 for injecting, the compressed air supplier 122 for supplying the compressed air so as to smoothly perform a series of reducing agent injecting functions on the reducing agent injector 120 side, and the sensor 119 The controller 123 controls the compressed air supply valve 124 based on the measured value to adjust the amount of reducing agent injection by the reducing agent injector 120, and the exhaust gas is connected to the engine 303 through the exhaust gas distribution line 112. And the reducing agent together, SCR reactor 113 for purifying the harmful substances contained in the exhaust gas is to take a systematic combination.

At this time, the SCR reactor 113 is passed through the exhaust gas and the reducing agent at the same time, by reacting the nitrogen oxides (NO _x ) with the reducing agent to reduce the nitrogen oxides (NO _x ) to nitrogen and water harmless to the organism (SCR catalyst ( 118 and an SCR chamber 117 containing the SCR catalyst 118 have a combined configuration.

Here, in the exhaust gas distribution path switcher 304 disposed on the exhaust gas distribution line 112, the distribution path of the exhaust gas on the engine 303 side is changed according to the situation. The function of switching to the exhaust gas distribution line 112 (if it is necessary to purify the exhaust gas), the exhaust gas distribution line 306 (if the exhaust gas is used for heating the SCR reactor 113), and the like. Will perform.

At this time, when the exhaust gas flows through the exhaust gas distribution line 306 on the engine 303 side, the exhaust gas flows through the inside of the heating box 307 and contacts the SCR chamber 117, and then the exhaust gas distribution line. By being discharged through 308, the SCR chamber 117, the SCR catalyst 118, and the like can be heated to a predetermined temperature (eg, 260 ° C.) or more.

On the other hand, even under such a system of the present invention, as described above, when the output amount of the engine 303 becomes large, the scale of the harmful substance reduction device 100 will inevitably increase in proportion to it. This is because, when the output amount of the engine 303 becomes large, the amount of exhaust gas generated from the engine 303 side also inevitably increases.

However, in proportion to the output of the engine 303, there are bound to be many limitations in inadvertently expanding the scale of the hazardous substance reducing device 100. This is because when the scale of the harmful substance reduction device 100 becomes large, for example, the space utilization efficiency degradation problem of the vessel 300, the land transportation of the large hazardous substance reduction device 100, the problem of impossible to enlarge the size of various valves This is because the back will inevitably occur.

Under such a sensitive situation, as shown in FIG. 3, in the present invention, a communication pipe such as a hull operation controller 301 in charge of the operation of the hull 300a, an engine driver 302 in charge of driving the engine 303, and the like. In the line, when the hull 300a is located at the ECA or ECA entry reserve point Y1 where the discharge of hazardous substances is strictly restricted (see Fig. 2), the engine 303 is controlled by adjusting the output of the engine 303 downwardly. In order to reduce the amount of exhaust gas discharged from 303, the engine power control device 200> will be additionally arranged (of course, the ECA entry reserve point Y1 may be adjusted according to the characteristics of the ship 300). May vary in position).

In this case, the engine output control apparatus 200 of the present invention may have a structure that is dependently installed in the program block of the engine driver 302 or the program block of the ship operation controller 301 according to the situation.

At this time, as shown in Figure 4, the engine output control device 200 according to the present invention is the interface module 201, the engine driver 302, the ship operating controller 301, the global positioning system ( GPS: operation information storage module 202 to communicate with the global positioning system (400), the hazardous substance detection sensor 130 (see FIG. 3) attached to the rear end of the SCR chamber 117 of the hazardous substance reducing apparatus 100, etc. , The hull position acquisition module 203, the ECA and the hull relative position determination module 204, the engine output factor control module 205, the purification of harmful substances emission module 206, the ECA entry determination module 208, etc. It will take a combination.

Here, the operation information storage module 202 side in the information storage area of the various operation information required for the engine output control service, for example, the registration information of the engine driver 302, the registration information of the ship operation controller 301, GPS Registration information of 400, registration information of the hazardous substance detection sensor 130, location information of the ECA (e.g., position coordinate information), ECA entry reserve point (Y1) reach determination criteria information, purification of harmful substances (harmful substance reduction device Reference amount information of the harmful substances contained in the exhaust gas purified through (100)), down-regulation reference information by engine output factor, up-regulation reference information by engine output factor, program component information required for the performance of each computer module By storing / managing program component information for connecting / maintaining communication sessions of each computer module, a series of engine power adjustment procedures according to the present invention can be normally performed without any problems. The secondary role that is so carried out.

Under such a situation that the infrastructure is equipped, as shown in Figure 5, the hull position acquisition module 203 side while communicating with the ship operation controller 301, GPS 400, etc. via the interface module 201, The procedure of acquiring the position information (for example, position coordinate information) of the hull 300a from them is carried out.

In this way, when the position information (for example, position coordinate information) of the hull 300a is completed, the relative position determination module 204 between the ECA and the hull communicates with the hull position acquisition module 203, whereby the acquisition is completed. The positional information (eg, positional coordinate information) of the hull 300a is read. In addition, the relative position determination module 204 side between the ECA and the hull communicates with the operation information storage module 202, and the position information (e.g., position coordinate information) of the ECA previously stored in the information storage area thereof, and the preliminary entry of the ECA. The procedure of extracting the determination information of the arrival point of the point Y1 is performed (see FIG. 5).

Through the above-described procedure, the position information (eg, position coordinate information) of the hull 300a, the position information (eg, position coordinate information) of the ECA, the ECA entry reserve point Y1 arrival determination reference information, etc. are completed. Then, the relative position determination module 204 side between the ECA and the hull proceeds a series of information comparison routine based on the ECA entry preliminary point (Y1) arrival determination reference information. Compare the positional information (eg, positional coordinate information) of the hull 300a with the positional information (eg, positional coordinate information) of the ECA. Through this, whether the hull 300a is located at the ECA or the ECA entry reserve point Y1. The procedure of determining the process is performed (see FIG. 5).

Under this procedure, when it is determined that the hull 300a is located at the ECA or the ECA entry reserve point Y1, the engine output factor adjustment module 205 communicates with the relative position determination module 204 between the ECA and the hull. Check the result. Thereafter, the engine output factor adjustment module 205 communicates with the operation information storage module 202 and performs a procedure of extracting down regulation reference information for each engine output factor previously stored in the information storage area thereof ( 5).

At this time, the engine output factor employed in the present invention is preferably a ship speed of the hull 300a, revolutions per minute of the engine 303, the fuel amount of the engine 303, the effective pressure of the engine 303 Etc. may be selected.

In this way, when the down-regulation reference information for each engine output factor is extracted, the engine output factor control module 205 side proceeds with a series of information generation routines based on this, for example, <AA speed of the hull 300a Decrease to SS>, <reduce Revolutions Per Minute of engine 303 to GG for YY minutes>, <reduce the fuel amount of engine 303 to KK for JJ minutes>, <engine 303 Reduce the effective pressure to NN for CC minutes>, and proceed with the procedure of generating a request message for the engine power factor down adjustment including the details (see FIG. 5).

Under such a procedure of generating the engine output factor down adjustment request message, the engine output factor control module 205 side from the time when the hull 300a enters the ECA, the amount of exhaust gas discharged from the engine 303 is a harmful substance reduction device. Reductions of ship speed of hull 300a and revolutions per minute of engine 303 so that it can be matched to the capacity of 100 (ie, within the range of the hazardous materials reduction processing capacity of hazardous materials reduction device 100). Per Minute) the amount of downward flow, the amount of fuel downward flow of the engine 303, the amount of effective pressure downward flow of the engine 303, etc. are set.

Through the above procedure, for example, <reduce the ship speed of the hull 300a to SS for AA minutes>, <reduce the revolutions per minute of the engine 303 to GG for YY minutes>, < When the engine output factor down adjustment request message including the details of reducing the fuel amount of the engine 303 to KK for JJ minutes> and <reducing the effective pressure of the engine 303 to NN for CC minutes> is generated, the engine is completed. The output factor adjustment module 205 communicates with the ship operation controller 301, the engine driver 302, etc. via the interface module 201, and generates the engine output factor down adjustment request message from the ship operation controller 301. Then, the procedure of transmitting to the engine driver 302 is performed (see FIG. 5).

Of course, through the above-described process, <reduce the ship speed of the hull 300a to SS for AA minutes>, <reduce the revolutions per minute of the engine 303 to GG for YY minutes>, <engine ( When the engine output factor down-regulation request message including the fuel consumption of 303) is reduced to KK for JJ minutes> and <the effective pressure of the engine 303 to NN for CC minutes>, the vessel is completed. The operation controller 301, the engine driver 302, and the like read the corresponding engine output factor down adjustment request message. After that, the ship operating controller 301, the engine driver 302, etc., adjust the ship speed of the hull 300a downward from the time when the hull 300a enters the <ECA entry reserve point Y1. Procedure>, <a procedure of down-regulating the revolutions per minute of the engine 303 from the time when the hull 300a enters the ECA entry reserve point Y1>, and <the ECA entry reserve point Y1 The procedure for lowering the fuel amount of the engine 303 from the time when the hull 300a enters>, and <The effective pressure of the engine 303 from the time when the hull 300a enters the ECA entry reserve point Y1 Procedure>, <procedure to lower the ship speed of the hull 300a from the time when the hull 300a enters the ECA>, <rpm of the engine 303 from the time of the hull 300a to enter the ECA ( Down-regulation of Revolutions Per Minute>, <down-regulation of fuel amount of the engine 303 from the time when the hull 300a enters the ECA>, <ECA From the time when the hull 300a enters, a procedure for lowering the effective pressure of the engine 303> is performed. Through this, the output of the engine 303 is adjusted downward, and finally, at the time when the hull 300a enters the ECA, the amount of exhaust gas discharged from the engine 303 corresponds to the capacity of the hazardous substance reducing device 100. It can be naturally reduced (that is, naturally within the range of the hazardous substance reduction treatment capacity of the hazardous substance reduction device 100).

As described above, in the present invention, the ship 300 is harmful in a communication pipeline such as the hull operation controller 301 in charge of the operation of the hull 300a and the engine driver 302 in charge of driving the engine 303. If the discharge of material is located at the ECA or ECA entry point where it is strictly prohibited, computerized to adjust various output factors of the engine 303 to minimize the amount of exhaust gas emitted from the engine 303 Module> provides systematic layout. Therefore, under the implementation environment of the present invention, on the hazardous substance reduction device 100 side, immediately after the start of the ECA operation of the hull 300a, the minimum amount of exhaust gas on the engine 303 side (or the minimum amount on the engine 303 side is harmful). Substances), it is possible to smoothly perform a series of harmful substance reduction functions. As a result, the ship operator can flexibly respond to the latest regulations on hazardous substances even when the scale of the hazardous substance reduction device is not increased (ie, the size of the hazardous substance reduction device is downsized).

On the other hand, as shown in FIG. 4, in the engine output control apparatus 200 of the present invention, in addition to the above-described respective computational modules, purifying harmful substance emission acquisition module 206, ECA entry determination module 208 Etc. are further arranged.

At this time, the purifying hazardous substances emission module 206 side while communicating with the hazardous substance detection sensor 130 attached to the rear end of the SCR chamber 117 of the hazardous substance reducing device 100, this hazardous substance detection sensor 130 The procedure of acquiring the quantity of the toxic substance (the toxic substance contained in the exhaust gas purified through the harmful substance reduction device 100) from the side is carried out (see FIG. 5).

In this way, when the amount of the purifying harmful substance (the harmful substance contained in the exhaust gas purified through the harmful substance reducing device 100) is obtained, the engine output factor control module 205 side obtains the purifying harmful substance discharge obtaining module ( 206) to read the amount of purifying hazardous substances. In addition, the engine output factor control module 205 is in communication with the operation information storage module 202, and proceeds with the procedure of extracting the reference amount information of the purifying harmful substances previously stored in its information storage area (FIG. 5). Reference).

Through the above-described procedure, when the amount of the purifying harmful substance, the amount of the purifying harmful substance, and the like are read / extracted, the engine output factor control module 205 proceeds with a series of information comparison routines to determine the amount and purify of the purifying harmful substance. Compare the amounts of hazardous substances with each other. Through this, it is determined whether or not the amount of the purifying harmful substances contained in the exhaust gas passing through the harmful substance reducing apparatus 100 exceeds the preset amount of the purifying harmful substances (see FIG. 5).

At this time, when it is determined that the amount of the purifying harmful substances contained in the exhaust gas passing through the hazardous substance reducing device 100 exceeds the preset amount of the purifying hazardous substances, the engine output factor control module 205 operates. Communication with the information storage module 202 is performed to extract down-regulation reference information for each engine output factor previously stored in the information storage area thereof. After that, a series of information generating routines are performed based on the extraction result. For example, <Reduce the ship speed of the ship 300a to SS for AA minutes>, and <Revolutions Per Minute of the engine 303, Engine output factors including details such as reduce to GG for YY minutes>, <reduce the fuel amount of engine 303 to KK for JJ minutes>, <reduce the effective pressure of engine 303 to NN for CC minutes> A procedure of generating a downlink request message is performed (see FIG. 5).

Through the above procedure, for example, <reduce the ship speed of the hull 300a to SS for AA minutes>, <reduce the revolutions per minute of the engine 303 to GG for YY minutes>, < When the engine output factor re-downgrade request message including the details of reducing the fuel amount of the engine 303 to KK for JJ minutes> and <reducing the effective pressure of the engine 303 to NN for CC minutes> is generated, The engine output factor adjustment module 205 communicates with the ship operation controller 301, the engine driver 302, and the like via the interface module 201, and sends the generated engine output factor re-down adjustment request message to the ship operation controller ( 301, the engine driver 302, and the like, may be transferred (see FIG. 5).

Of course, through the above-described process, <reduce the ship speed of the hull 300a to SS for AA minutes>, <reduce the revolutions per minute of the engine 303 to GG for YY minutes>, <engine ( Receive the engine output factor re-downgrade request message containing the details such as reducing the fuel amount of 303) to KK for JJ minutes> and <reducing the effective pressure of the engine 303 to NN for CC minutes>. The vessel operation controller 301, the engine driver 302, etc., reads the engine output factor re-downlink request message, and according to the details, <procedure to re-downline the ship speed of the hull 300a>, <engine Re-slowing the Revolutions Per Minute of (303)>, <Re-slowing the fuel amount of the engine 303>, <Resizing the effective pressure of the engine 303> Etc. As a result, the amount of the exhaust gas and harmful substances discharged from the engine 303 can be further reduced, and as a result, the harmful substances contained in the exhaust gas purified through the harmful substances (the harmful substance reducing device 100). ) Can also be greatly reduced.

On the other hand, the ECA entry determination module 208 in cooperation with each of the preceding computer module to communicate with the hull position acquisition module 203, thereby obtaining the position information (eg, position coordinate information) of the hull 300a obtained ). In addition, the CA entry determination module 208 communicates with the operation information storage module 202 and proceeds with the procedure of extracting the location information (eg, position coordinate information) of the ECA previously stored in its information storage area. (See FIG. 5).

Through the above-described procedure, when the position information (eg, position coordinate information) of the hull 300a and the position information (eg, position coordinate information) of the ECA are read / extracted, the ECA entry determination module 208 determines a sequence By comparing the information, the position information (eg, position coordinate information) of the hull 300a and the position information (eg, position coordinate information) of the ECA are compared, whereby the hull 300a is out of the ECA. The procedure of determining the process is performed (see FIG. 5).

Under this procedure, when it is determined that the hull 300a is out of the ECA, the engine output factor adjustment module 205 communicates with the ECA entry determination module 208, checks this, and then stores the operation information storage module 202. Communication with each other, the procedure of extracting up-regulation reference information for each engine output factor previously stored in its information storage area is performed (see FIG. 5).

In this way, when the up-regulation reference information for each engine output factor previously stored in the information storage area of the operation information storage module 202 is extracted, the engine output factor adjustment module 205 performs a series of information generation routines based on this. For example, <increase ship speed of hull 300a to SS for AA minutes>, <increase Revolutions Per Minute of engine 303 to GG for YY minutes>, <engine ( Increase the amount of fuel of 303) to KK for JJ minutes> and < increase the effective pressure of engine 303 to NN for CC minutes > (See FIG. 5).

Through the above procedure, for example, <increase the ship speed of the hull 300a to SS for AA minutes>, <increase the revolutions per minute of the engine 303 to GG for YY minutes> A request message for the engine power factor upward adjustment request is generated, such as <increase the fuel amount of the engine 303 to KK for JJ minutes> and <increase the effective pressure of the engine 303 to NN for CC minutes>. Upon completion, the engine output factor adjustment module 205 communicates with the ship operation controller 301, the engine driver 302, and the like through the interface module 201, and operates the vessel output factor upward adjustment request message. The transmission to the controller 301, the engine driver 302, etc. is performed (see FIG. 5).
