Abstract

The invention discloses a water sealing fire retardance explosion venting device which comprises a fire retardance device and an explosion venting machine. The fire retardance device comprises a fire retardance barrel body, an air inlet pipe, an air outlet pipe and a water filtering metal ring net. One end of the air inlet pipe is placed out of the fire retardance barrel body, the other end of the air inlet pipe extends into the fire retardance barrel body and is inserted to the position below a sealing water liquid level, and the water filtering metal ring net is arranged above the sealing water liquid level and is arranged outside the air inlet pipe in a sleeving mode. The explosion venting machine comprises an explosion venting barrel body, an exhaust pipe and an explosion venting pipe. The exhaust pipe and the explosion venting pipe are communicated with the explosion venting barrel body. The fire retardance barrel body is communicated with the explosion venting barrel body through the air outlet pipe and a communication pipe arranged at the bottom. An explosion piece is arranged in the explosion venting pipe. An air outlet end pipe opening of the air inlet pipe is sealed. An exhaust hole is formed in the side wall, placed below the sealing water liquid level, of the air inlet pipe. The exhaust hole is connected with an air guiding pipe. Air guiding holes for air discharging are distributed in the air guiding pipe. The instability and the acute fluctuation of the liquid level caused when air is discharged from the device exhaust pipe can be avoided, water level control is convenient, and the safety and the reliability of the device are improved.

Description

technical field

[0001] The invention belongs to the field of coal mine gas utilization, and relates to a water-sealed fire arresting and explosion venting device. Background technique

[0002] In recent years, with the rise of the coal mine gas power generation industry, the gas safety delivery system has also been rapidly popularized and applied. The low-concentration gas pipeline safety delivery system has played an important role in preventing low-concentration gas pipeline explosions and protecting coal mine pumping stations and mine safety. protective effect. As an important safety protection device, the water-sealed fire arresting and explosion-venting device has few functions in the past, and no water-sealed fire-arresting and explosion-venting device with relatively complete functions has been developed according to the characteristics of coal mine gas power generation. The risk and cost of safe operation of gas pumping stations and gas power stations great. Existi...
