Coal Mine Safety Regulations
Article 182
(6) In the system of dry extraction of gas using pumps on the suction side of the pipeline in coal dust explosion mining, safety devices with functions of flame arresting, backflow prevention, and explosion prevention must be installed and regularly inspected.
Article 184
(4) When utilizing gas, safety devices with functions of flame arresting, backflow prevention, and explosion prevention must be installed in the gas utilization system.
(5) When the concentration of extracted gas is below 30%, it shall not be used directly as fuel gas. During pipeline transportation, gas utilization, or venting, relevant standards must be followed and safety technical measures must be formulated.
Product Introduction
Can eliminate flames generated inside gas pipelines, providing flame arresting, backflow prevention, and explosion prevention functions.
Suitable for installation of automatic powder spraying explosion suppression devices on gas pipelines where gas extraction and utilization are required.
The working principle of this product is that when a flame occurs inside the pipeline, the flame sensor receives the flame signal and transmits it to the PLC. After analyzing the wavelength and other signals to confirm it is not a false alarm, the PLC sends a signal to the explosion suppressor, triggering the gas generator inside the suppressor to spray extinguishing powder, cutting off the flame transmission medium inside the pipeline and thus extinguishing the fire.
