1 to 5, a marine engine exhaust gas mixing system 100 according to the present embodiment includes a marine engine 101, a marine engine 110, a marine engine 111, a marine engine 112, a burner device 120 for treating marine engine exhaust gas, A mixing member 130, and a reactor 140.

In the present embodiment, the marine engines 101, 110, 111, and 112 are illustratively composed of the main engine 101 of the ship and the view engines 110, 111, and 112 used for power generation, . In the present embodiment, the view engines 110, 111, and 112 are shown as three examples, and the present invention is not limited thereto.

Each of the marine engines 101, 110, 111, and 112 generates the exhaust gas 10 during operation.

The main branch discharge pipe 104 is an internal hollow pipe type pipe through which the exhaust gas 10 generated in the main engine 101 can be discharged. The view branch discharge pipe 114 is connected to a plurality of the above- (110, 111, 112) are formed in the same shape as the number of the view engines (110, 111, 112) in the hollow pipe type pipe in which the exhaust gas (10) And the branched branch pipes 114 are connected to branching portions of the view engines 110, 111 and 112 where the exhaust gas 10 is discharged.

The burner apparatus 120 for treating the marine engine exhaust gas includes a burner main body 121, an exhaust gas inflow hole 122, a urea water injection member 123 and a flame injection member 160.

The burner main body 121 provides a space in which the exhaust gas 10 flowing into the burner main body 121 can be heated and mixed with the urea.

The exhaust gas inflow hole 122 is formed in the burner main body 121 so that the exhaust gas 10 can flow into the burner main body 121 from the marine engines 101, .

The urea water injection member 123 can inject urea containing ammonia for treating nitrogen oxide in the exhaust gas 10 flowing through the exhaust gas inlet hole 122 into a liquid form or the like It is.

The flame spraying member 160 is disposed between the urea water injection member 123 and the urea water injection port 122 so that the exhaust gas 10 flowing through the exhaust gas inlet hole 122 can be heated. And the flame 163 is sprayed through the nozzle 161 toward the exhaust gas 10.

Conventionally, a device for injecting the urea water and a burner capable of raising the temperature of the exhaust gas 10 to a temperature suitable for smooth reaction of the urea water have been applied as separate elements. However, the burner device for treating the marine engine exhaust gas The flame spraying member 160 raises the temperature of the exhaust gas 10 introduced into the burner apparatus 120 for treating the marine engine exhaust gas, A system for processing the exhaust gas 10 of the marine engines 101, 110, 111, and 112 can be simplified.

The flame spraying member 160 is installed at a head portion of the burner main body 121 and the exhaust gas 10 introduced through the exhaust gas inflow hole 122 passes through the flame of the flame injection member 160 Is supplied to the nozzle 161 of the injection member 160 and is heated by the flame 163 generated from the nozzle 161 to flow from the head portion to the tail portion of the burner main body 121.

The flame 163 injected from the flame injection member 160 is injected from the nozzle 161 of the flame injection member 160 through the primary flame 164 and the primary flame 164 And the urea water injection member 123 injects the urea water into the secondary flame 165 in the form of droplets in the form of droplets. Thus, oxidation of the urea water injected from the urea water injection member 123 is suppressed, and the urea water can be heated.

The flame spraying member 160 is coupled to an outside air inlet portion 125 through which the necessary oxygen can be supplied during the combustion process for generating the flame 163 with the flame injection member 160.

The outside air introduction part 125 can introduce outside air through the outside air inflow pipe 126. The outside air introduced through the outside air inflow pipe 126 flows into the flame spraying part 160 at a high pressure Pressure air blower 127. The high-

 Since the outside air can be introduced into the burner body 121 through the outside air inlet 125 in the combustion process for generating the flame 163 with the flame injection member 160, Oxygen can be supplied.

Reference numeral 105 denotes a main exhaust gas inflow pipe for introducing the exhaust gas 10 flowing through the main branch discharge pipe 104 into the exhaust gas inflow hole 122 and reference numeral 106 denotes a main exhaust gas inflow pipe Is a main high-pressure blower that causes the exhaust gas (10) flowing through the pipe (105) to flow at a high pressure.

Reference numeral 150 denotes a main engine valve capable of opening and closing the main exhaust gas inflow pipe 105.

Reference numeral 115 denotes a view exhaust gas inlet pipe through which the exhaust gas 10 flows into the exhaust gas inlet hole 122 through the view branch discharge piping 114. Reference numeral 116 denotes a view exhaust gas inlet pipe 115 to the high-pressure side of the exhaust gas 10 flowing through the high-pressure side.

The main exhaust gas inlet pipe 105 and the exhaust gas inlet pipe 115 are communicated with the exhaust gas inlet hole 122 so that the main exhaust gas inlet pipe 105 communicates with the exhaust gas inlet pipe The exhaust gas 10 flowing into the burner unit 120 and the exhaust gas 10 flowing into the burner apparatus 120 for treating the marine engine exhaust gas from the exhaust gas inlet pipe 115 are exhausted from the exhaust gas And may be introduced into the inlet hole 122.

The exhaust gas (10) flowing through the main exhaust gas inlet pipe (105) flows through a part of the exhaust gas (10) flowing along the main branch discharge pipe (104) The waste heat contained in the exhaust gas 10 flowing through the gas inlet pipe 105 is used as the heating energy in the flame injection member 160.

Here, a relatively small amount of the exhaust gas 10, such as the exhaust gas 10 of about 20% of the exhaust gas generated in the main engine 101, flows into the main exhaust gas inlet pipe 105, the amount of the exhaust gas 10 to be heated up compared with the conventional one is reduced, so that the heating energy by the flame spraying member 160 can be reduced.

The urea water injection member 123 may be formed by measuring nitrogen oxides or the like in the exhaust gas 10 flowing into the burner apparatus 120 for treating the marine engine exhaust gas through the main exhaust gas inlet pipe 105, The urea water injection quantity at the nozzle can be determined.

The exhaust gas 10 flowing through the exhaust gas inlet pipe 115 flows through the entire exhaust gas 10 flowing along the branch discharge pipe 114, The waste heat contained in the exhaust gas 10 flowing through the exhaust gas inflow pipe 115 is used as the heating energy in the flame injection member 160.

Since the waste heat of the exhaust gas 10 generated in the view engines 110, 111, and 112 is relatively high, the temperature rising energy of the flame spraying member 160 can be reduced.

As described above, by measuring the nitrogen oxide or the like in the exhaust gas 10 flowing into the burner apparatus 120 for treating the marine engine exhaust gas through the exhaust gas inlet pipe 115, The urea water injection amount in the member 123 can be determined.

Reference numeral 124 denotes a burner body 121 in which the exhaust gas 10 introduced into the burner body 121 is heated while passing through the burner body 121 and mixed with the urea water, And can be introduced into the mixing member 130, which will be described later.

The mixing member 130 is disposed in the combustion engine exhaust gas treatment burner unit 120 so that the mixture of the exhaust gas 10 and the urea water mixed in the burner unit 120 for treating the marine engine exhaust gas, The exhaust gas 10 bypassing the exhaust gas 10 can be mixed with each other.

The exhaust gas 10 flowing through the main discharge pipe 103 branched from the main branch discharge pipe 104 and the mixture 20 discharged from the mixture discharge pipe 124 flow to the mixing member 130 The mixture 20 having a relatively high temperature flows through the main discharge pipe 103 branched from the main branch discharge pipe 104 to increase the temperature of the exhaust gas 10 having a relatively low temperature .

The reactor 140 separates contaminants of the exhaust gas 10 and the mixture 20 bypassed from the burner apparatus 120 for treating the ship engine exhaust gas mixed in the mixing member 130 .

As described above, the exhaust gas 10 flowing through the mixing member 130 and the mixture 20 flow into the reactor 140 to filter contaminants.

For example, the mixing member 130 is formed to have a predetermined length, and a shelf inclined downward is coupled to the inner wall of the pipe in a plurality of spaced apart shapes.

Reference numeral 141 denotes a filter installed in the reactor 140 to filter contaminants of the exhaust gas 10 and the mixture 20 flowing in the mixing member 130.

In this embodiment, the exhaust gas 10 which has been heated to a high temperature through the reactor 140 can be introduced into the reactor 140, so that the sulfur poison such as a mixture of sulfur and ammonia on the surface of the filter 141 can be removed .

The exhaust gas 10 and the mixture 20 from which the pollutants are filtered by the filter 141 are discharged to the outside through a discharge pipe 143 coupled to the end of the reactor 140.

Hereinafter, the operation of the marine engine exhaust gas mixing system 100 according to the present embodiment will be described.

As shown in FIG. 3, the main engine valve 150 is opened when the engine 110, 111, or 112 is not driven and the main engine 101 is driven.

The view engines 110, 111 and 112 are in an undriven state and the main engine 101 is in a state in which the view engines 110, 111 and 112 are in a state in which the exhaust gas 10 And the exhaust gas 10 is generated in the main engine 101. [

The exhaust gas 10 generated in the main engine 101 flows into the main branch discharge pipe 104 and a part of the exhaust gas 10 flows into the main exhaust gas inlet pipe 105 to be supplied to the burner apparatus for treating the marine engine exhaust gas And the exhaust gas 10 bypassing the burner apparatus 120 for treating the marine engine exhaust gas flows to the main discharge pipe 103.

In this state, the exhaust gas 10 flowing into the main exhaust gas inflow pipe 105 is heated by the flame generated by the flame injection member 160 in the burner main body 121, The mixture 20 is formed by mixing with the urea water sprayed from the injection member 123 and the mixture 20 is discharged through the mixture discharge pipe 124.

The exhaust gas 10 flowing into the burner apparatus 120 for treating the marine engine exhaust gas through the main exhaust gas inlet pipe 105 is exhausted from the exhaust gas 10 generated in the main engine 101, For example, about 20%.

In this state, the exhaust gas (10) flowing through the main discharge pipe (103) bypasses the burner apparatus (120) for treating the marine engine exhaust gas and the mixture flowing through the mixture discharge pipe (20) can be introduced into the reactor (140) while being smoothly mixed with each other through the mixing member (130).

The exhaust gas 10 flowing along the mixture 20 and the main discharge pipe 103 through the mixing member 130 is mixed with the exhaust gas 10 having a relatively low temperature to heat the mixture 20 The exhaust gas 10 flowing along the main discharge pipe 130 can be heated by transferring the exhaust gas 10 flowing along the main discharge pipe 130 to the exhaust gas 10.

That is, a part of the exhaust gas 10 generated in the main engine 101 is heated to a temperature required by the burner apparatus 120 for treating the marine engine exhaust gas, The exhaust gas 10 bypassed from the processing burner unit 120 can also be heated by the mixing member 130 so that all of the exhaust gas 10 generated in the main engine 101 can be heated by the flame It is possible to reduce the heating energy used in the flame spraying member 160 of the burner apparatus 120 for treating the marine engine exhaust gas and to prevent the flame member 160 from being relatively heated By heating a small amount of the exhaust gas 10, the working time can be shortened.

Meanwhile, as shown in FIG. 5, the main engine valve 150 is switched to a closed state in a state where the view engines 110, 111 and 112 are driven.

The exhaust gas 10 generated in the main engine 101 flows to the main discharge pipe 103 branched from the main branch discharge pipe 104. [ The exhaust gas 10 generated in the view engines 110, 111 and 112 flows from the view branch discharge pipe 114 to the view exhaust gas inlet pipe 115, And then flows into the burner apparatus 120.

In this state, the exhaust gas 10 flowing into the burner apparatus 120 for treating the marine engine exhaust gas is heated in the burner main body 121 and mixed with the urea water to form the mixture 20 And the mixture 20 may be discharged through the mixture discharge pipe 124.

The exhaust gas 10 flowing into the burner apparatus 120 for treating the marine engine exhaust gas through the exhaust gas inlet pipe 115 is exhausted from the exhaust gas 10 generated in the main engine 101, The temperature of the flame spraying member 160 can be further reduced.

The exhaust gas 10 generated in the view engines 110, 111 and 112 is, for example, about 340 ° to 400 ° and the exhaust gas 10 generated in the main engine 101 is, for example, 220 °.

In this state, the exhaust gas (10) generated in the main engine (101) and bypassing the burner apparatus (120) for treating the ship engine exhaust gas and flowing through the main discharge pipe (103) The mixture 20 flowing through the mixing chamber 124 can be smoothly mixed with the mixing member 130 and flow toward the reactor 140.

Here, the mixture 20 and the burner device 120 for treating the marine engine exhaust gas are bypassed through the mixing member 130, and the exhaust gas flowing along the main discharge pipe 103 is discharged to the exhaust The gas 10 is mixed and the heat of the mixture 20 is transferred to the exhaust gas 10 to bypass the burner apparatus 120 for treating the marine engine exhaust gas, So that the exhaust gas 10 having a relatively low temperature can be heated.

That is, the exhaust gas 10 generated in the main engine 101 flows along the main discharge pipe 103 by bypassing the burner apparatus 120 for treating the marine engine exhaust gas, The exhaust gas 10 generated in the exhaust gas treatment apparatus 110, 111, and 112 flows into the burner apparatus 120 for treating the ship engine exhaust gas along the exhaust gas inlet pipe 115 to be heated, (20) and discharged to the mixture discharge pipe (124).

In this state, the mixture 20 discharged to the mixture discharge pipe 124 and the burner apparatus 120 for treating the marine engine exhaust gas are bypassed and the exhaust gas flowing along the main discharge pipe 103 10 are mixed through the mixing member 130 and the heat of the mixture 20 is transferred to the exhaust gas 10 bypassed from the ship engine exhaust gas treatment burner apparatus 120 and divided The exhaust gas 10 bypassed from the marine engine exhaust gas treatment device 120 can be heated even by bypassing the marine engine exhaust gas treatment burner device 120, 160, and the flame member 160 raises a relatively small amount of the exhaust gas 10, so that the working time can be shortened.

As described above, the mixture 20 and the exhaust gas 10 heated to an appropriate temperature and flowing into the reactor 140 smoothly filter contaminants through the filter 141 of the reactor 140 .

The exhaust gas 10 and the mixture 20 from which the pollutants are filtered by the filter 141 are discharged to the outside through a discharge pipe 143 coupled to the end of the reactor 140.
