The beneficial effect of the utility model:
Reduce the discharge amount of main generator nitrogen oxides of exhaust gas (NOx);
The nitrogen oxide initial ejection amount of every generator is 9.1g/kWh, and behind SCR (SCR), the content of nitrogen oxide is reduced in the 2.0g/kWh, satisfies the emission request of Norway authorities; Reduce the delivery temperature of pipeline outlet.The generator outlet delivery temperature is about 450 degrees centigrade, and through after the cooled with seawater, the exhaust outlet temperature is reduced to below 60 degrees centigrade, prevents that personnel's accident from scalding.
Working principle is to utilize the nitrogen oxides in ammonia and the waste gas to react, and produces the nitrogen G&W, thereby reduces the discharging of nitride.Utilize seawater to spray and get into outlet pipe, make EGT descend.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Embodiment
Below in conjunction with concrete embodiment the utility model has been done further description.
As shown in Figure 1, the ship side vent systems comprises successively, assembly parts (1), urea injection syringe (2), SCR unit (3), one-level seawater fill assembly (4), baffler (5), wave resistance short tube (7) and outboard exhaust box (9);
Has one half bend (6) between said SCR unit (3) and the one-level seawater fill assembly (4);
One end of said assembly parts (1) connects main frame, and the other end connects urea injection syringe (2), has an arm (1-1) on the straight length of said assembly parts (1), and this arm (1-1) is used for releasing and prevents that any liquid from flowing backwards to main frame;
The urea liquid that said urea injection syringe (2) is used for 40% is injected into outlet pipe;
Said SCR unit (3) one ends connect urea injection syringe (2); The other end is connected with one half bend (6); Contain 56 cellular catalytic module in the said SCR unit (3), each module is all arranged with level in a certain order, and this catalytic module is used for catalyzing urea solution and nitrogen oxide reacts; Thereby the content of nitrogen oxide is reduced in the 2.0g/kWh, nitrogen hydride is controlled at 5mg/m
3In;
Said one-level seawater fill assembly (4) one ends link to each other with one half bend (6); The other end connects baffler (5), and said one-level seawater fill assembly (4) can be injected into seawater in the outlet pipe; Be used to reduce the temperature of waste gas; Let waste gas become descendingly, protect the assembly in vent systems downstream simultaneously, and can reduce system noise by up;
Said baffler (5) comprises body (5-2) and is connected short tube and secondary seawater fill assembly (5-1), and said body (5-2) is a Cylindrical object, and its diameter is 806mm, can the temperature of waste gas be reduced to 60 ℃, and noise is reduced 20-24dB; Said connection short tube and secondary seawater fill assembly (5-1) are positioned at the bottom of body (5-2), are used to connect an end of wave resistance short tube (7), form an angle between said connection short tube and secondary seawater fill assembly (5-1) and the body (5-2), the angle ranging from 92 degree;
The other end of said wave resistance short tube (7) links to each other with outboard exhaust box (9); This outboard exhaust box (9) mainly plays the effect of buffering exhaust; And the sink drain of unnecessary seawater through the below be discharged in the seawater; The latus rectum of said wave resistance short tube (7) is 350mm, on wave resistance short tube (7), has row's outboard valve (8).This row's outboard valve (8) mainly is to be used for when main frame is not worked, and isolated vent systems contacts with extraneous seawater.This valve is the pneumatic remote-control valve, and with main frame interlock, valve is also opened during host-initiated, valve was can late release too high to prevent the inner back pressure of vent systems when main frame stopped, thereby damaged other assemblies.
