Abstract
The invention discloses a working method of a vehicle exhaust purification device for secondary combustion of vehicle exhaust. The device comprises a shell; multiple arc heat pieces are arranged on the inner wall of the shell in sequence from outside to inside; gaps in the tail ends of the arc heat pieces form gas outlets; gas inlets are formed in the centers of side walls of the shell, and are communicated with the gas outlets through gas inlet pipes; combustion assistant gas chambers are formed between the side walls of the shell and the adjacent arc heat pieces; combustion assistant gas pipes are arranged in the centers of the arc heat pieces; combustion assistant gas generation bottles are arranged on the combustion assistant gas chambers near the ends of the gas inlet pipes; and a combustion assistant agent is filled in the combustion assistant gas generation bottles. The device can perform secondary combustion for incompletely burnt gas and carbon particles in the vehicle exhaust to generate water and other harmless gas, and is simple in structure, low in cost and more environment-friendly.
Description
Technical field
The present invention relates to environmental protection field, it is specifically related to the method for work of a kind of combustion-type automobile exhaust gas purifying installation.
Background technology
The tail gas that in running car, afterbody is discharged is usually in black-and-blue, and these are all the incomplete combustions due to gasoline, the material producing the atmosphere pollutions such as carbon monoxide, sulfide and carbon granule and being detrimental to health. These material major parts can carry out secondary combustion under the help of combustion-supporting gas, if carrying out burn processing when these objectionable impuritiess can be discharged in air, generate the material such as harmless water and carbonic acid gas, then the pollution finally discharging the vehicle exhaust in air will reduce greatly.
Summary of the invention
It is an object of the invention to overcome prior art Problems existing, it is provided that the method for work of a kind of combustion-type automobile exhaust gas purifying installation.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions: the method for work of a kind of combustion-type automobile exhaust gas purifying installation, this device comprises housing, described inner walls is disposed with multiple arc backing from outside to inside, described arc backing tip gap forms air outlet, at the sidewall center of described housing, inlet mouth is set, described inlet mouth is connected described air outlet by intake ducting, combustion-supporting air chamber is formed between the sidewall of described housing with adjacent arc backing, and described arc backing center is provided with combustion-supporting feed channel, the contiguous described intake ducting end of described combustion-supporting air chamber is provided with combustion-supporting gas generation bottle, it is filled with ignition dope in described combustion-supporting gas generation bottle.
Preferably, the end of described arc backing is the thin slice material of easily heating, and the camber line opening direction of described arc backing is carried on the back to described air outlet, and described combustion-supporting feed channel is provided with check valve, and described check valve only allows described combustion-supporting gas indoor gas outwards to circulate.
Described method of work comprises: during running car, and the high-temperature high-speed airflow of afterbody discharge will cause arc backing terminal temperature to raise, and finally light vehicle exhaust in the effect of combustion-supporting gas and high temperature arc backing.
The invention has the beneficial effects as follows: adopt technical solution of the present invention, it is possible to gas imperfect combustion in vehicle exhaust and carbon granule are carried out secondary combustion, generate water and other innocuous gas, and structure is simple, cost is low, more environmental protection.
