Abstract

The invention discloses a gas pumping and releasing pipeline explosion suppression fire retarding device which solves the problems that an existing gas pumping and releasing pipeline has great potential safety dangers. An explosion suppression system comprises a controller, a flame detector and a fire extinguisher. The output end of the flame detector is connected with the input end of the controller. The output end of the controller is connected with the input end of the fire extinguisher. A fire retarding system comprises a shell body and a metal mesh located in the shell body. An explosion venting plate is arranged at the top of the shell body. A gas inlet pipe and a gas outlet pipe are respectively arranged on the left side wall and the right side wall of the shell body. Sealing water drowning the bottom of the gas inlet pipe is arranged at the bottom of the shell body. The shell body on the outer side of the sealing water is provided with a water level sensor and a water level indicator. The water level sensor and the water level indicator are communicated with the sealing water. The gas pumping and releasing pipeline explosion suppression fire retarding device effectively restrict gas explosion of a pumping and releasing pipeline, eradicates occurrence of chain explosion of a pumping and releasing pipe network, is high in fire retarding performance, and has the advantages of being simple in structure, convenient to operate, and low in cost. Moreover, the suppression process is high in speed and effective.

Description

technical field [0001] The invention relates to the field of coal mine ventilation and safety, in particular to an explosion suppression and fire arresting device for a gas drainage pipeline. Background technique [0002] Since the underground gas transmission pipelines are connected in parallel and in series, once a local leakage occurs in the underground gas transmission pipeline and the fire source enters the pipeline, after combustion and deflagration, it will spread along the pipeline and spread to other areas, which is not conducive to the entire gas Safety of extraction conveying system. Contents of the invention [0003] In order to solve the problem of relatively large potential safety hazards in existing gas drainage pipelines, the invention provides an explosion suppression and fire arresting device for gas drainage pipelines. [0004] The present invention is realized by adopting the following technical solutions: the explosion suppression and fire arresting d...
