Abstract

The invention discloses an industrial waste gas combustion device and a method thereof. The invention comprises an industrial waste gas channel, at least one primary air channel, and at least one ignition device which is arranged at the terminal end of the industrial waste gas combustion device by extension, wherein, the industrial waste gas combustion device further comprises at least one secondary air channel; the industrial waste gas channel, the primary air channel and the secondary air channel are all ring-shaped channels; the industrial waste gas channel is arranged at the outer side of the primary air channel in a rotating way; and the secondary air channel is arranged at the outer side of the industrial waste gas channel in a rotating way. As the invention uses a structure that the industrial waste gas channel, the primary air channel and the secondary air channel are mutually separated, the combustion is safe and reliable; as a trumpet-shaped ring-shaped channel is used by each channel, the fullness of the flame can be enhanced, the length of the flame can be reduced, and the combustion efficiency can be improved.

Description

technical field

[0001] The invention relates to a waste heat recovery device and method, in particular to a waste heat recovery device and method of industrial waste gas. Background technique

[0002] The industrial waste gas discharged by most chemical enterprises contains combustible gases, such as H 2 , CO, CH 4 etc. These industrial waste gases are directly discharged into the atmosphere, which wastes resources and pollutes the environment. Since the composition of combustible gas in industrial waste gas only accounts for 10-20%, the calorific value of waste gas is not high, about 500-2000Kcal / Nm 3 , and the gas supply pressure is very low, about 0.4 ~ 1.25Kpa, the calorific value of general natural gas is about 8500Kcal / Nm 3 , Ordinary gas burners require an air supply pressure of 10-150Kpa, so this kind of industrial waste gas with low calorific value and air pressure cannot be burned normally and stably by ordinary gas burners.
