Abstract
A process for burning benzene-contained waste gas to purify air during cineration features that said waste gas is first heated to 300-400 deg.c by heater, then mixed with gas in incinerator, and finally it is burned at 750-850 deg.c in the incinerator. Its advantages include low cost and high air-purifying effect.
Description
The present invention relates to a kind of burned waste gas purification method, particularly a kind of waste gas containing benzene burns purification method.
At present general waste gas containing benzene purification method in the past more adopts directly discharging, but pollution is arranged, and then adopts absorption method or Production by Catalytic Combustion Process, but the cost height, purifying rate is low, and catalyst easily lost efficacy.
The purpose of this invention is to provide a kind of direct burning purification method and purify waste gas containing benzene.
Technical scheme of the present invention is that a kind of waste gas containing benzene of design burns purification method, it is characterized in that: waste gas containing benzene is heated to 300 ℃-400 ℃ by heating furnace, waste gas containing benzene after will heating again feeds incinerator, with after the combustion gas mixing in incinerator with 750 ℃ of-850 ℃ of burning points burning back dischargings.
Advantage of the present invention is with low cost, purifies waste gas containing benzene with directly burning purification method effectively.
Below in conjunction with a technological process embodiment the present invention is elaborated,
Waste gas containing benzene is heated to about 350 ℃ by heating furnace, waste gas containing benzene after will heating again feeds incinerator, by lance-type burner directly burn light diesel fuel mix with waste gas containing benzene the back in incinerator with the burning of 800 ℃ of burning points, the benzene in this moment waste gas containing benzene is cleaned directly discharging of back.
