Description
Technical Field
The invention relates to the technical field of tail gas treatment equipment, in particular to a tail gas particle catcher.
Background
Compared with gasoline engine, diesel engine has the features of high power, wide application range, high cost performance, low use and maintenance cost, etc. and may be used widely in various fields. However, the exhaust emission of diesel engines is poor, and PM, CH, CO and NOx emitted are important factors for forming haze; in some cities with severe haze, the pollutant emitted by diesel engines has even exceeded the pollutant emitted by industrial enterprises and has become a leading factor in causing haze. Therefore, how to reduce the pollutant emission of diesel engines has become the subject of many enterprises and personal researches.
At present, for PM emission of a diesel engine, a particle catcher is generally arranged at an exhaust outlet of the diesel engine to perform physical interception, but as the starting time of the diesel engine increases, more and more particles are accumulated in the particle catcher, if the particles are not cleaned timely, the back pressure of the engine is finally increased until the extreme condition of dead holding is reached. Currently, there are three general types of schemes for cleaning particulate matter collected in a particulate trap:
The first type is to raise the exhaust temperature by intermittent oil injection at the exhaust port to reach the ignition point of the particulate matter, so that the particulate matter is burned into gas for exhaust. However, the technical scheme has the difficulty that the quantity and the timing of oil injection are difficult to grasp, a complex electric control device is added, and the risk of burning the whole particle catcher caused by high system cost and improper oil injection exists.
The second scheme is to add a noble metal catalyst containing platinum and the like in front of the particle catcher so as to decompose the particles. However, this solution requires a high sulfur content in the fuel and a high exhaust temperature in the diesel engine: high sulfur content can lead to catalyst poisoning, and too low an exhaust temperature can even lead to catalyst failure. The catalyst poisoning or failure will plug the particle trap and may in turn risk burning out.
The third scheme is to directly use a ceramic particle catcher to physically catch the particles, but the biggest problem of the scheme is cleaning after the particles are caught, and at present, the ceramic particle catcher filter material carrier can only be transported into a special high-temperature furnace for heating, so that the particles are completely burnt, then the furnace is stopped for cooling, and the method of back blowing and ash cleaning by compressed gas is adopted. The cleaning method has the defects of high cleaning cost, complexity, long time consumption and scrapped filter material carriers which can be recycled for several times.
