ZYBG12/2 Automatic Powder Spraying and Explosion Suppression Device for Gas Pipeline Transportation

ZYBG12/2 Automatic Powder Spraying and Explosion Suppression Device for Gas Pipeline Transmission (hereinafter referred to as “Explosion Suppression Device”) is installed on pipelines with gas and dust combustion or explosion hazards. When a gas combustion or explosion accident occurs, the flame signal and the explosion shock wave signal are identified through the sensor, and the explosion suppression controller receives the fire signal, and the explosion suppressor instantly sends out the control driving signal to trigger the action of the explosion suppressor, and the explosion suppressor quickly sprays ABC ultra-fine dry powder fire extinguishing agent to extinguish the flame in the initial combustion or explosion propagation process, which has the function of inhibiting flame combustion and further propagation of the explosion flame.

It is suitable for gas extraction pipelines, evacuation pipes, and gas transmission pipelines for power generation, and can quickly extinguish the explosion flame, suppress the explosion in the minimum range, and reduce disaster losses. The device can be operated in the underground pipeline environment of coal mines with explosive gases such as methane and coal dust, and is used in the environment with gas and dust combustion or explosion hazards, and is widely used in coal mine gas transmission pipelines.
