Abstract

The invention relates to a full-automatic coal mine ventilation air methane collecting device, and belongs to the technical field of coal mine associated equipment. When exhaust operation is carried out, diffusion towers are used as a main exhaust device, the diffusion towers are used as an auxiliary exhaust device, the exhaust air is discharged through the diffusion towers, and the exhaust air isdetected by gas concentration sensors inside the diffusion towers. If the presence of gas is detected, rotating mechanisms are controlled by a control system to rotate, so that an air outlet on a rotating air duct is connected with a ventilation air methane pipeline, the exhaust air containing the gas enters a ventilation air methane using device through the ventilation air methane pipeline; andwhen the gas concentration sensors detects that no gas exists in the exhaust wind, the air outlet is connected with an exhaust pipe when the rotating mechanisms rotates to perform normal exhaust. Thefull-automatic coal mine ventilation air methane collecting device simplifies the structure of an exhaust device, the effect of discharging the ventilation air methane and common exhaust is achieved and the discharge of common exhaust is not affected. The full-automatic coal mine ventilation air methane collecting device improves the efficiency of gas collection and utilization rate of the gas.

Description

technical field [0001] The invention relates to a fully automatic coal mine exhaust air collection device, which belongs to the technical field of coal mine supporting equipment. Background technique [0002] In the process of coal mining, a large amount of gas in the coal seam flows into the mining space, and mine ventilation is one of the basic means of gas control. Therefore, the methane concentration in the exhaust air of the coal mine is very low (less than 1%). And it has the characteristics of unstable concentration and large air volume. In order to improve the safety of coal mine production, a large amount of gas is discharged into the atmosphere with the mine ventilator. [0003] The direct discharge of coal mine exhaust gas not only aggravates the greenhouse effect, but also wastes energy. With the global emphasis on the greenhouse effect and the development of science and technology, the methane treatment technology in coal mine exhaust air has very great develo...
