Low concentration gas:
Low-concentration gas refers to gas with a methane concentration of 8%-30%. The gas extraction volume of coal mines is huge, of which at least 2/3 are low-concentration gases of coal mines with a methane concentration of less than 30%. If not used, a large amount of energy will be wasted.
The explosion range of gas under normal temperature and pressure is 5%-16%; gas engines use the energy generated by gas combustion to drive the generator to generate electricity.
Low-concentration gas transport has an explosion risk. In order to solve this problem, our company has designed and developed a low-concentration gas transport support system.
Low concentration gas delivery system:
Function: transport low-concentration gas from the gas transmission end to the gas consumption end, and ensure the quality of the gas transmission end; the gas transmission end involved is a gas extraction station, and the gas consumption end involved is a low-concentration gas generator set.
Installation: Directly connect the three-way pipe port at the drain outlet of the gas extraction station, without pipeline renovation.
System Introduction:
The low-concentration gas delivery guarantee system connects the gas transmission end and the gas consumption end. Multiple guarantee measures are taken throughout the process, including three main measures: fire prevention, explosion prevention, and explosion transmission, which are realized by single-type water seal fire-retardant and explosion-release device, fine water mist generator, fire arrester and other equipment. In addition, there are multi-stage auxiliary systems such as filters, gas-liquid separators, lightning rods, grounding systems, and discharging systems. The main function is to reduce the risk of low-concentration gas transportation and prevent the pipeline from spreading to the gas transmission end and gas use end. At the same time, the filter and gas-liquid separator ensure that the low-concentration gas meets the requirements of the gas-using end, and grounding, lightning rods, etc. help the conveying pipelines avoid lightning strikes, electric sparks and other dangers. Comprehensively ensure the delivery while ensuring the quality of gas use.
The low-concentration gas delivery guarantee system mainly includes electric discharge valves, water seal fire blockers, wet discharge valves, dry fire blockers, basket filters, fine water mist generators, gas-liquid separators, as well as auxiliary equipment such as valves, pressure gauges, temperature gauges, water pumps, and pools.

Introduction to the main equipment functions of the system:
Dry flame arrester : Using the principle of flame quenching in the slit, it uses stainless steel plates to bend and overlap into a fire extinguishing layer with very small gaps. When a flame is generated in the pipeline, it will be blocked by a dry flame arrester, extinguishing the flame or reducing the fire. It plays a hindering role in the spread of flames.
Basket filter : mainly uses the mechanism of interception and collision to filter impurities such as particles, water vapor and dust in the delivered gas. It prevents impurities from blocking the dry flame arrester and extends the service life of the dry flame arrester and pipe valves.
Wet discharge valve : The pressure of the control pipeline is adjusted through changes in water level, released overpressure in the conveying pipeline, and protected the safety of the conveying equipment and pipelines.
Fine water mist generator : The effect of cooling and dilution reduces the temperature and concentration of the Nvas in the conveying pipeline and inhibits the occurrence of combustion.
Water seal fire blocker : The liquid level is controlled through the internal overflow device to adjust the pipeline pressure. It not only ensures that the gas can flow smoothly in the conveying pipeline, but also realizes the fire blocking function, and also plays a role in suppressing the propagation of explosions.
Gas-liquid separator : It has multiple functions such as dehydration, dust removal, and pressure stabilization. It is a gas purification and treatment equipment.
