Pneumatic high-pressure micro-fog dust collector

Abstract

The invention discloses a pneumatic high-pressure micro-fog dust collector for mines. The pneumatic high-pressure micro-fog dust collector comprises a tank body, wherein a water-in pipe is arranged in the tank body, the water-in end of the water-in pipe penetrates through the tank body and is connected with a pressurized water pipe, the water-out end of the water-in pipe is connected to a high-pressure hose, and a pressure reducing valve, a back flush filter and a particle filter are arranged in the part, in the tank body, of the water-in pipe; the other end of the high-pressure hose is connected to a gas inlet of a turbocharger, an exhaust gas inlet of the turbocharger is connected with a gas-in pipe, the other end of the gas-in pipe penetrates through the tank body and is connected with a pressurized air pipe, and a pneumatic T joint is arranged at the part, in the tank body, of the gas-in pipe; a gas outlet of the turbocharger is hermetically connected with a water-out pipe, and the other end of the water-out pipe penetrates through the inner wall of the tank body and is connected with a sprayer. When pressurized air which is conveyed from the ground flows across a turbine booster pump, pressurized water is pressurized to the water-out pipe by air compressor blades at a high speed, and the flowing rate of the pressurized water is greatly increased, so that the water is sprayed into a fog form at the sprayer part to absorb surrounding dust. Through the adoption of the structure, dangerous coefficients which are caused by the use of power driving are avoided, and meanwhile, power cost is reduced.

Description

technical field [0001] The invention relates to an underground dedusting device, in particular to a pneumatic high-pressure micro-mist dedusting device. Background technique [0002] Coal mine underground roadway will produce a lot of dust during mining, coal mining, drilling rig drilling, etc., resulting in a high concentration of underground dust and low visibility, which seriously affects the health of underground workers. The generated dust will cause huge safety hazards and dust explosions are prone to occur Disaster accident. At present, mine-used spray pumps are mainly used for underground dust removal, but this patent needs to be equipped with mine-used explosion-proof motors, which are large in size and consume a lot of energy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pneumatic high-pressure micro-mist dedusting device, which does not need to use electricity in the underground, reduces the risk...
