Technical field
The utility model relates to a kind of diesel engine high-performance exhaust gas cleaner, can be widely used in take diesel engine as the vent gas treatment of the passenger vehicle of power, truck, fork truck, steamer, the engineering machinery such as generator set and mine, tunnel, down-hole, belongs to engine exhaust purifying catalyst converter manufacturing technology field.
Background technique
Along with popularizing of energy saving standard theory, the good market prospects of global diesel engine purifier.Because diesel engine is than petrol engine fuel-economizing 30%, the low 30%-45% of CO2 emissions, therefore diesel oil changes into the important development direction into automobile industry.The tail gas that diesel engine emissions goes out comprises complicated organic substance and inorganic matter, and main component is carbon monoxide, hydrocarbon and particulate matter (PM), causes serious harm to environment and the mankind.For this reason, Europe started in 2008 to implement Europe V emission standard for car and light-duty commercial truck, exhaust gas cleaner is as the standard configuration of diesel powered vehicles, engineering machinery, diesel engine, and the environmental regulation of U.S.'s increasingly stringent also impels exhaust gas cleaner installing and using in diesel engine.Chinese Government has also stepped up the improvement to environment in recent years, has put into effect relevant environmental law Laws & Regulations, the discharge of preventing pollution thing from source.
At present, the purification plant processing diesel motor exhaust has following three kinds of modes:
One, ability of swimming processor, it has certain effect to the purification of sulphide, but water filtering type cleaning system hydrophily is poor, only can purify comparatively granule, still can discharge with waste gas more greatly containing oil particles.And when motor runs, exhaust gas temperature is higher, the water in water filter box can part evaporate, and needs timing supplementing water, adds labor workload.Water filter box volume is also comparatively large, and have higher requirement to the space of installing space and equipment transport passage for transporting, water filtering type cleaning system also can cause the secondary pollution of water body simultaneously.
Two, high-pressure electrostatic precipitation, the carbon soot particles in motor exhaust is adsorbed on stainless steel tube wall by the high-pressure electrostatic that the method relies on electrode tube to produce instantaneously.The purifying effect of this kind of method to black smoke is higher, but floor space is large and have that Keep Clear-High Voltage.Adsorb because black smoke particle only does, need the carbon soot particles in timing cleaning Stainless Steel Tube, can secondary pollution be caused.
Three, the purifier of bypass tube is installed; the method use initial stage effectively can remove the black smoke in motor exhaust, when after use a period of time, carbon soot particles can block ceramic element, directly opens bypass tube discharge in this case; can pollution be produced, lose the object of purification.
