Coal Mine Safety Regulations
Article 182
(6) In the dry gas extraction pump suction-side pipeline system used for coal dust explosion prevention during coal mining, safety devices with functions to prevent backfire, backflow, and explosions must be installed and regularly inspected.
Article 184
(4) When utilizing gas, the system used for gas utilization must be equipped with safety devices that prevent backfire, backflow, and explosions.
(5) When the concentration of extracted gas is lower than 30%, it shall not be used directly as fuel gas. When transporting via pipelines, utilizing the gas, or venting it, relevant standards must be strictly followed, and comprehensive safety technical measures must be put in place.
Product Overview
It can effectively extinguish flames generated inside gas pipelines, providing protection against flame flashback, backflow, and explosions.
A gas pipeline automatic powder suppression system is required for installation on gas pipelines where gas extraction and utilization are necessary.
This product works by detecting a flame in the pipeline: when a flame occurs, the flame sensor captures the flame signal and transmits it to the PLC. After the PLC analyzes signals such as wavelength and confirms that the detection is accurate (not a false alarm), it sends a signal to the explosion-suppression device, triggering the gas generator inside. The resulting extinguishing powder is then rapidly ejected from the device, effectively cutting off the flame's propagation medium within the pipeline and thereby suppressing the fire.
