Movable mineral porous medium stage purification dust removing device and dust removing method

Abstract

The invention discloses a movable mineral porous medium stage purification dust removing device. The movable mineral porous medium stage purification dust removing device comprises a movable mechanism, a lifting mechanism and a changeable porous medium stage purification main body; the lifting mechanism is arranged on the movable mechanism; the changeable porous medium stage purification main bodyis arranged on the lifting mechanism; the movable mechanism comprises a vehicle body; rubber wheels are arranged on the rear side of the bottom of the vehicle body; a telescopic support rod is arranged on the front side of the bottom of the vehicle body; the changeable porous medium stage purification main body comprises a casing; an air inlet is formed in the rear end of the casing; an air outlet is formed in the front end of the casing; a gas sensor is arranged at the air inlet; an air deflector, a dust retaining net, a replaceable prefiltering layer, a replaceable stage filtering layer anda fan are arranged in the casing from rear to front. The invention also provides a movable mineral porous medium stage purification dust removing method using the device. According to the movable mineral porous medium stage purification dust removing device and the movable mineral porous medium stage purification dust removing method disclosed by the invention, by adopting a dry type dust removing mode, the problem of forming a mud blockage filtering layer by wet dust removal is solved, and the demands of purification and dust removal of local air in an underground coal mine can be met.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety dust removal and purification, and in particular relates to a movable mining porous medium classification purification dust removal device and a dust removal method. Background technique [0002] Coal mine operations produce a large amount of dust, and the dust dispersed in the air may explode, and it is easy for miners to suffer from pneumoconiosis, posing a threat to coal mine safety and personnel health. [0003] High-concentration dust is generated during underground operations in mines, such as coal cutting, tunneling, and reloading. These dusts disperse or settle in the roadway with wind flow, and some of them are discharged to the ground. The dust of these different particle sizes has a serious impact on the underground operation of coal mines, the service life of equipment, the life safety of miners and the atmospheric environment. Coal dust is a kind of mine dust. When the conce...
