an exhaust gas burner

Abstract

An exhaust gas burner, which is installed at the lower part or the head of the incinerator, and a plurality of burner nozzles are arranged inside, and each burner nozzle is equipped with an independent ignition gun, a fuel pipeline rising pipe and a valve. To the bottom, there are outlet contraction section, combustion chamber, waste gas collection cabin, mixing air collection cabin, and combustion air collection cabin; the exhaust gas burner is connected with the incinerator body through the exit contraction section, and the waste gas collection cabin, The mixing air collection cabin and the combustion-supporting air collection cabin are all equipped with independent inlets, and each collection cabin is connected to the corresponding outlet on the distribution mixing plate through the corresponding riser pipe to form independent exhaust flow channels, mixing air flow channels, Combustion-supporting air flow channel; the fuel pipeline rising pipe of each burner burner is coaxially arranged with the combustion-supporting air rising pipe, and the outlet is arranged at the combustion-supporting air outlet. The exhaust gas burner proposed by the invention has high integration degree, compact and reliable structure, sufficient incineration, high thermal efficiency and convenient operation.

Description

technical field [0001] The invention belongs to burner technology and is suitable for waste gas incineration in industries such as oil refining, chemical industry, medicine and power plant, and specifically relates to a waste gas burner. Background technique [0002] In the refining and chemical industry, a large amount of toxic and harmful waste gas or waste gas with a certain calorific value is discharged during the production process. From the perspective of environmental protection and energy saving, it is not allowed to vent directly, and it needs to be treated by an incinerator before being discharged. In particular, during the operation of catalytic cracking units in refineries, incomplete catalyst regeneration and aerobic combustion produce a large amount of flue gas containing about 3-10% (V) CO and a small amount of combustible gas. This part of flue gas not only has a certain temperature (about 600 ° C) ), and contains a certain amount of CO gas that can be furthe...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects existing in the existing CO incinerator and propose a waste gas burner. The technical problem to be solved is to make it have a high degree of integration, a compact and reliable structure, sufficient incineration, high thermal efficiency, easy operation, and effective Solve the defects of existing equipment such as complex manufacturing process, scattered structure, difficult operation, poor combustion effect, etc., so that it is more suitable for practical use
