Description

A kind of exhaust gas cleaner of convenient regeneration

Technical field

This utility model is related to the technical field of tail gas filtering, more particularly to a kind of exhaust gas cleaner of convenient regeneration.

Background technology

Internal combustion engine is wide because of good economy, dynamic property, reliability and relatively low CO, HC (Hydrocarbon) discharge General application, but the Particulate Emission of internal combustion engine can reduce microgranule by particle trapper is installed on exhaustor than more serious Discharge.With the growth of working time, particle trapper filters internal microgranule to be increased, and engine back pressure will rise, and affects interior These microgranules need to be removed, i.e. the regeneration of filtering bodies by the normal work of combustion engine by chemically or physically method.

Regeneration techniques be particle trapper can on internal combustion engine normal work key technology, and at present micro particle catching The technological difficulties of device.By regeneration point initiative regeneration and passive regeneration.

Initiative regeneration usually improves the temperature inside particle trapper using outside energy, make microgranule ignition so as to It is converted into gas.Or by the regeneration of the mechanical systems such as reverse jet, vibration.Shortcoming is to increase combustion system, electrical heating system System, high-pressure air source, vibrating device and corresponding control system, so as to reduce the reliability of particle trapper, increased entirety Manufacturing cost and use cost.Each system exist accordingly filter element group it is overheated burn, regeneration efficiency is low, or cannot adapt to vehicle and make The problems such as using.

Ignition temperature of the passive regeneration by using some catalyst degradation microgranules, makes it in normal I. C. engine exhaust At a temperature of ignition decompose.Realized by major ways such as catalyst coat, fuel oil additives.Current domestic oil product sulfur contains Amount is higher, toxic action can be produced to catalyst so that catalyst failure in use, causes the particle trapper cannot effectively again It is raw, there is blocking.

Generation current unit tail gas disposal technique with Water spray, DPF (particle trapper), DOC (oxidation catalytic converter)+ DPF (particle trapper) is technical way, and wherein Water spray mainly removes the float of part larger particles in tail gas, right The overall removal effect of particulate matter is poor.DPF system is preferable to particulate matter removal effect, but cannot be effectively clear after the blocking of duct Remove, cause thrashing use.DOC+DPF systems can alleviate the situation of duct blocking, extend use time, but still cannot It is fully solved the problem of blocking.

Utility model content

For technical problem present in prior art, the purpose of this utility model is：A kind of tail of convenient regeneration is provided Air purifying apparatus, with preferable vent gas treatment effect, meanwhile, exhaust gas cleaner can be made to reach the effect for rapidly and efficiently regenerating Really.
