Technical field
The utility model relates to a kind of land with mobile diesel exhaust gas cooling device, relates to especially that control has the exhaust cooling device of the land of strict demand with mobile diesel engine to ambient temperature.
Background technique
As everyone knows, the diesel engine delivery temperature of working under full load is very high, and diesel engine power give full play to external world that air temperature is very sensitive, along with the density of air temperature rising air can continue to descend, the engine supercharger unit time is pressed into the volume in the fresh space in the engine cylinder-body will continuous decrease, because the combustion mixture in piston/cylinder can not get sufficient burning, engine power output will continue to descend.Generally all adopt the simple heat-insulating structure that coats for domestic diesel engine power engine unit, diesel power generation unit, diesel oil water pump assembly exhaust cooling method.Cooling jacket cooling or water heat source exchanger cooling, its cooling-down effect is poor, can not finely reach heat-insulating cooling effect.Especially narrow in the unit mounting point, the installing space air flow property is relatively poor, have inflammable gas, ignitable dust in the place of inclement condition and the air causes the position of burning easily because temperature is high, in case certainly will cause air temperature to raise in the rising of this mounting point engine exhaust temperature, influence the performance of engine power, the healthy and safe meeting of operator is caused very big influence.So it is just strict more to the diesel engine exhaust temperature requirement in this use mounting point.
For addressing the above problem, domestic patent application 200720086081.7 proposes to adopt the method that installs the water drencher additional to reduce the diesel engine exhaust temperature.It mainly is to draw seawater by cooling waterpump from seawater to come and then the control engine exhaust temperature by the drencher spray, this device is mainly used in marine engine, what sacrifice is a part of water flow of cooling waterpump, and the cooling water that it uses mainly is a seawater, though this device can effectively reduce the marine engine delivery temperature, if but water pump is not with mobile diesel-engine equipment in the land, nexhaustible seawater is not done under the situation of cooling water resources as seawater, use this cooling device just unrealistic on mobile diesel powered machine in the land.Secondly the power source of this device cooling waterpump is a power supply, and work in the open air with mobile diesel unit in the land, if do not have power supply or other to obtain easily and utilizable power source in the extremely abominable field of condition, cooling waterpump has just lost the effect of driving source, therefore it just can't be for this cooling device brings into play its effect with locomotor in the land, thereby is subjected to significant limitation on service condition.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and a kind ofly carrying the air compressor that water tank and diesel engine carry and come work of proposing do not need to increase power source, and the land that just can reach the exhaust cooling effect is with mobile diesel exhaust gas mist cooling device.
Technical solution of the present utility model is, the land with diesel engine exhaust mist cooling device is: the diesel engine exhaust house steward is connected with the suction port of sprayer by securing means, the exhaust end of sprayer is connected by securing means with the silencing apparatus intake manifold, sprayer is located in the swelling water tank, be fixed with row's nozzle on the housing of sprayer, the water intake of nozzle is connected with spraying constant voltage water pipe, spraying constant voltage water pipe is provided with the high pressure water water intake, and swelling water tank is provided with pressurization suction tude and cooling water suction tude.
The equal flange of securing means described in the technical solution of the present utility model and securing means.
The pressurization suction tude of the swelling water tank described in the technical solution of the present utility model is connected with the pressurization main frame by breather check valve, and into water one-way valve is housed on the cooling water inlet pipe, and swelling water tank is provided with Decompression valves, pressure gauge and blowdown valve.
Be provided with the water-level control apparatus of forming by float valve and ball float in the swelling water tank described in the technical solution of the present utility model.
Diesel engine exhaust mist cooling device working principle of the present utility model is: the fresh water behind the purification filtering is entered spraying constant voltage water pipe by be pressurized to 0.8MP in airtight container from the high pressure water water intake, by nozzle ejection diameter be the fog particles of 10-20 micron with after waste gas that diesel engine is discharged mixes, utilize water flash evaporation thermal diffusivity to come to lower the temperature to the waste gas of diesel engine discharge.The utility model is provided with spraying device on the diesel engine exhaust road, the air compressor that carries with diesel engine is to the tank compressed air, and the water of tank enters into spraying device by pipeline and carries out mist cooling under the effect of air pressure.When being diesel engine starting, the pressurization main frame that can drive pressurization carries out compressed action to air, pressurized air is exerted pressure to tank with regard to continual, cooling water in the tank is under the effect of air pressure, enter spraying constant voltage water pipe by the high pressure water water intake, when pressure reached nozzle injection pressure, the cooling water of high pressure will be sprayed onto the high-temp waste gas of discharging with diesel engine in the sprayer fast from nozzle to be mixed, come evaporative cooling water by high-temp waste gas, to have taken away heat.When motor quits work, open the Decompression valves on the tank, cooling water just can be pressed in the tank automatically, when water level arrival upper limit water level, under the active force of ball float, float valve is closed, stop to go up water, shut Decompression valves simultaneously, unit is task again.
The utility model has the advantages that:
1, reasonable in design, compact structure, be simple and easy to dress, widely applicable, be easy to promote.
2, the air compressor that carries of application engine is done the driving source of this device cleverly, structure optimization, reduces cost, and adaptability is stronger.
