Embodiment:
Consult Fig. 1, Fig. 2, Fig. 3, the exhaustor of boat diesel engine is connected with the exhaust port 15 of the passage of heat 1；The water system of boats and ships is connected with the water supplement port 411 of water tank 4, electric cabinet is connected with high-pressure electrostatic asher 12 and anion generator 13.
Present invention employs the passage of heat 1 and spray channel 3 that are set up in parallel；And between the passage of heat 1 and spray channel 3, it being provided with forced-ventilated passage 2, this setting makes to complete in the passage that atomization process and exhaust emissions process are different at two, it is achieved that the atomization of tail gas end processes.
Work process below in conjunction with the present invention is further described below:
During work, the offgas duct that boat diesel engine is discharged is entered by the exhaust port 15 of the passage of heat 1, first catalyzed filtration core 11 filters, owing to oxidation catalyst filter core 11 is the net-like spacer being coated with metal platinum, under the oxidation and reduction of oxidation catalyst filter core 11, the harmful gas such as the CO carbon monoxide discharged by ship tail gas, HC Hydrocarbon and NOx nitrogen oxides is changed into harmless carbon dioxide, water and nitrogen；
Tail gas continues flowing and through high-pressure electrostatic asher 12 in the passage of heat 1, owing to high-pressure electrostatic asher 12 exists electric field between hollow steel pipe and the high voltage electrostatic rod in axle center, electric field exists free electronics and ion, after the exhaust gas flow of dust-laden enters electric field, dust and ion collision and adhere to charged, form charged grit to hollow steel pipe or high voltage electrostatic rod two polar motion and to deposit so that tail gas is aoxidized further；
Tail gas is entered forced-ventilated passage 2 by the elbow at the passage of heat 1 top by ajutage interface 14 subsequently, under the effect of metal HEPA net 22, dust particle in tail gas is filtered and falls into the bottom of forced-ventilated passage 2 by metal HEPA net 22 so that the particulate matter in tail gas is filtered；
Finally, filtered tail gas enters into spray channel 3 by metal HEPA net 22 through flange port 32, by the spray pipe network of spray decomposition apparatus 31 and fog-spray nozzle, tail gas is implemented again atomized dust settling to process, the fine particle that minority is overflowed is avoided to discharge from the top of spray channel 3, the gas processed is emptied by the top of spray channel 3, the particle dust being atomized condensation and the dust particle filtered by metal HEPA net 22 drop down onto with spray channel 3 and hold bucket 33, water tank 4 is entered therewith through water return outlet 413, drainage screen 43 in water tank 4 filters Posterior circle and uses, it is complete that ship tail gas smoke abatement of the present invention controls haze process.
For slowing down the exhaust back pressure that diesel engine is produced by the present invention, prevent channel vent not smooth, the present invention is provided with turbocharger 21 in forced-ventilated passage 2, the setting of turbocharger 21 can force tail gas to pass through metal HEPA net 22, reduce the metal HEPA net 22 resistance to air-flow, to slow down the exhaust back pressure that diesel engine is produced by the present invention；
For further tail gas being implemented exterminating bacterium, the present invention is provided with anion generator 13 in the passage of heat 1, and under the effect of turbocharger 21, anion is by charge particles more in tail gas, and make the microgranule attracted each other together become heavier, force catalyzed conversion PM2.5 microgranule and toxic gas, finally fall down from spray channel 3.
The present invention is also provided with water supplement port 411, sewage draining exit 412, water return outlet 413 and outlet 414 on water tank 4, and is spray pipe network and fog-spray nozzle water supply with the water pump 42 of outlet, and water supplement port 411 is water tank make-up water source, and sewage draining exit 412 is used for cleaning water tank.
