Abstract

The invention discloses an ultralow-emission low-concentration gas safe combustion device. The ultralow-emission low-concentration gas safe combustion device comprises a pipeline, the pipeline is sequentially provided with an adjusting valve, an automatic quick cut-off valve, a three-way pipe, a dry-type flame arrester and a conical cavity with holes from left to right, a combustion cylinder is arranged at the end of the pipeline, an automatic control system is arranged on the pipeline, and the conical cavity with the holes is located in the combustion cylinder. A high-temperature-resistant alloy fiber braided fabric is arranged in the conical cavity with the holes, an ignition device is arranged in front of the pipeline and the conical cavity with the holes, a blowing fan is installed at the end of the three-way pipe, and a check valve is installed between the blowing fan and the three-way pipe. The automatic control system consists of an automatic control cabinet, a pressure sensor positioned in front of the adjusting valve and the automatic quick cut-off valve, and a methane concentration sensor positioned between the three-way pipe and the dry-type flame arrester. The research and development of the ultralow-emission low-concentration gas safe combustion device can fill the blank that the low-concentration gas cannot be directly combusted and utilized, and thoroughly solve the problem that the low-concentration gas cannot be directly combusted and utilized.

Description

technical field [0001] The invention relates to the technical field of low-concentration gas treatment, in particular to an ultra-low-emission low-concentration gas safe combustion device. Background technique [0002] my country's "Coal Mine Safety Regulations" stipulates that when the concentration of gas extracted from coal mines is lower than 30%, it cannot be directly burned as gas, so low-concentration gas combustion has always been a restricted area. [0003] The gas extracted from most coal mines in my country is low-concentration gas. At present, it is directly discharged into the air because it cannot be burned and utilized. It has not only caused a lot of waste of resources and energy for a long time, but also methane in the extracted gas is a serious greenhouse gas. The greenhouse gas effect is 21 times that of carbon dioxide. A large amount of direct gas emission intensifies the greenhouse effect and seriously damages the quality of the atmospheric environment. ...
