This utility model discloses a safety performance testing chamber for mining electromechanical equipment, including a chamber body, an explosion-proof door, an observation window, a top sealing mechanism, an intermediate sealing partition, a foundation, and pipeline interfaces. The chamber body is a rectangular steel structure, using a composite design of steel plates and grid-shaped reinforcing ribs, and is made of carbon steel and stainless steel composite materials, making it vibration-resistant and explosion-proof. The intermediate sealing partition is removable, dividing the chamber body into two small compartments or forming a complete large chamber, flexibly adapting to the testing of small or large diesel engines. The top sealing mechanism uses a U-shaped groove and a venting membrane seal, allowing for rapid pressure relief in the event of an explosion. The side walls are equipped with a rotating explosion-proof door and a high-temperature tempered glass observation window for easy entry, exit, and observation. The foundation is fixed with anchor bolts, and the interior and exterior of the chamber are coated with antistatic, flame-retardant, and rust-proof paint. This utility model can withstand the impact of a methane-air or methane-hydrogen-air mixture explosion, ensuring safety; it is suitable for verifying the safety performance of diesel engines in underground coal mines, and has the advantages of high efficiency, safety, and economy.

The present application relates to the technical field of mine ventilation air methane utilization, and particularly relates to a mine ventilation air methane comprehensive treatment system and method based on coal-electricity integration, which realizes effective recovery and utilization of mine ventilation air methane waste heat by setting a ventilation air methane air heat exchanger to exchange heat between mine ventilation air methane and cold air in a plant area in winter, and conveying the heated air to a plant area living area ventilation or heating system. The technical scheme of the present application is that mine ventilation air methane is treated by heat exchange and condensation and then enters a boiler system for methane oxidation; water vapor in the ventilation air methane is condensed and collected by heat exchange and cooling, so as to reduce the water content of the ventilation air methane, and then the treated ventilation air methane is sent to a power station boiler secondary air system, so that trace methane in the ventilation air methane is oxidized into carbon dioxide under high-temperature conditions in the boiler furnace, so as to reduce the greenhouse effect of the mine ventilation air methane and improve the boiler combustion efficiency. The present application solves the problems of resource utilization and greenhouse gas emission reduction of mine ventilation air methane in the prior art.
