Description

Tail gas fires purifier again

The present invention relates to a kind of tail gas that is widely used in the motor vehicle tail gas clean-up and fire purifier again.

Existing motor vehicle, its rear portion discharge tail gas has caused severe contamination to atmosphere, has destroyed the ecological balance, and people's physical and mental health also has been subjected to grievous injury, has become one of human public hazards, directly the life and health and the living environment of endangering and coercing the mankind.

The object of the present invention is to provide a kind of simple in structurely, be easy to make, black smoke is eliminated in fully burning, purifies air, and the tail gas of protection environment fires purifier again.

In order to achieve the above object, tail gas of the present invention fires purifier again, comprise blower fan, adjust the modulating valve of air mass flow, shaft is installed in down the air conduit on the shaft of chamber, the jet dividing plate of porous between following chamber and firing chamber, be installed in combustion chamber stove igniter on one's body, the suction tude that an end is installed on the tail gas exhaust port, the other end is installed on the furnace bottom, tail gas directly feeds the firing chamber; Said firing chamber is provided with combustion gas body exhaust port again in furnace roof portion.

Tail gas of the present invention fires purifier again, and its working principle is: under the effect of blower fan, air enters chamber under the stove by air conduit, enters the firing chamber on top then by the jet dividing plate of porous, and simultaneously, tail gas directly also constantly enters the firing chamber by suction tude.Light by igniter, inflammable gas in the tail gas and the burning of the oxygen mix in the combustion-supporting air, thus the unburnt combustible substance in tail gas is further fully burnt in the firing chamber, the Purge gas after the burning enters atmosphere by exhaust port.

Tail gas of the present invention fires purifier again, in order to reach clean-burning requirement, utilizes the air spray to match with combustion-chamber shape, makes tail gas and air mixing even.Utilize the jet dividing plate of the very little porous in aperture, improve jet pressure, make gas injection reach the height uniform state, thereby reach the purpose of perfect combustion.Practice shows: under tail gas and the uneven situation of air mixing, and the place that will cause mixed gas dense (tail gas is many) in combustion process, tail gas is because of anoxic, and it is slow to burn, and makes incomplete combustion and exhaust occurs to emit a small amount of black smoke; In contrast, in mixed gas rare (air be'ss many) place, air but is not fully utilized.This just need make flammable tail gas obtain sufficient oxygen as early as possible under the least possible situation of excess air, and perfect combustion in time.This that is to say, requires tail gas and air as far as possible promptly to mix, and perfect combustion in time.

Tail gas of the present invention is burning purifier again, in when burning, consider that institute's air that supplies can not just in time absolutely react with flammable tail gas, some air of federation is to have walked interlude, for flammable tail gas is as far as possible fully burnt, to add suitable allowance during air-supply.When air quantity is excessive, burning has not been had institute's benifit, increased ventilation loads, increased power consumption.Automatically change air quantity by modulating valve, make tail gas and air be mutually an optimum ratio, reach optimum Match.

Tail gas of the present invention fires purifier again, adopts the mode of mechanical ventilation, because the air mass flow of natural ventilation is too little, generally, is difficult to provide the oxygen of abundance, is used for exhaust combustion.

Tail gas of the present invention fires purifier again, lights inflammable mixture by igniter, makes it fire burns.Catching fire and burning of fuel must have under sufficient oxygen and the certain temperature condition and could realize.

Tail gas of the present invention fires purifier again, owing to contain flammable pollutant, especially flammable carbon black in the tail gas.Directly show the tail gas over-emitting black exhaust.Carbon black is unburnt product, can burn in the firing chamber, produces bright flame during burning.When flammable carbon black and oxygen mix were relatively poor, burning slowed down, and it is very long that flame draws.Usually said smoke elimination is not to be to say to eliminate flue gas, because products of combustion can not be eliminated, eliminates smoke and is meant the elimination black smoke, promptly eliminates carbon black.By the air mass flow adjustment, if accomplish to keep higher fire box temperature, the tail gas inflammable matter well mixes with air, can realize not over-emitting black exhaust.

Tail gas of the present invention fires purifier again, and constituent part is little, and technology is simple, is easy to make, and is convenient to install.Can fully burn, can effectively eliminate black smoke, thereby purify air, the protection environment.Prove through prototype test: respond well.

Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation.

Fig. 1 is the structural representation that tail gas of the present invention fires purifier again;

Fig. 2 is the another kind of structural representation that tail gas of the present invention fires purifier again.

In Fig. 1, Fig. 2, present embodiment tail gas fires purifier again, comprises blower fan 1, modulating valve 2, and shaft 3, air conduit 4 is evenly distributed with the jet dividing plate 5 of some apertures, igniter 6, tail gas suction tude 7 on circumference; Said air conduit 4 is installed in down on 8 shafts of chamber, and said firing chamber 9 is at the tail gas inlet hole a of furnace bottom setting, the exhaust port b that the top is provided with.

In Fig. 2, present embodiment tail gas fires purifier again, said shaft, be marked with in the vestibule cooling water medium 10 this be because burning mixture in the combustion chambers burn process, discharge a large amount of heats, cause the heating surface temperature too high,, can effectively reduce the heating surface temperature by adding the cooling water medium.

Present embodiment tail gas fires purifier again, is not limited to illustrated vertical installation form, according to the structure of offgas duct on the motor vehicle and the structure of vehicle itself, install flexibly, and both can be vertical, horizontal installation form, can be again the installation form of other directions.

Claims

1, a kind of tail gas fires purifier again, it will be levied and be, comprise blower fan, adjust the modulating valve of air mass flow, shaft is installed in down the air conduit on the shaft of chamber, the jet dividing plate of porous between following chamber and firing chamber, be installed in combustion chamber stove igniter on one's body, the suction tude that an end is installed on the tail gas exhaust port, the other end is installed on the furnace bottom, tail gas directly feeds the firing chamber; Said firing chamber is provided with combustion gas body exhaust port again in furnace roof portion.
