Problems solved by technology
The dust removal measures in the prior art mainly adopt two kinds of low-pressure spray and high-pressure spray. Low-pressure spray dust removal has low water pressure, wastes water resources, cannot effectively reduce coal dust with small particles, and has an efficiency of less than 70% for respirable dust; Spraying in coal mines consumes a lot of water resources, and the effect is not very good. It cannot completely remove the fine particles, and it is not conducive to the discharge of dust after precipitation. Moreover, this method is easy to cause safety accidents, which is harmful to power supply lines and equipment. Strict requirements, and cannot form a dust removal system, and there are many blind spots in dust removal
In addition, the coal mine underground tunnel drilling rigs generate the most dust, which directly threatens the health of workers. The existing dust removal methods cannot effectively reduce the concentration of underground dust, and the dust removal efficiency is low, energy consumption is high, and it is not environmentally friendly.

The invention discloses a dust suction and removal device applied to coal mine operation in a limited space. The device comprises a spiral pipeline, a first lighting device, a first dust concentration detector, a centrifugal fan, an industrial motor, a dust suppressant water tank, a bonding filter screen, a spraying device, an automatic flushing pump, a pipeline inner wall nozzle, a second dust concentration detector, a granularity detector, a second lighting device, a sedimentation tank, a first filter plate, a filter tank, a second filter plate, a dust suppressant storage tank and the like. Dust removal operation in a limited space is achieved by designing a spiral pipeline, and the problem that the dust removal difficulty is large due to narrow space is solved; most dust removal devices only adopt a spray dust removal measure, but the dust removal efficiency is greatly improved by mounting the bonded filter screen in the pipeline, and an automatic cleaning device is mounted beside the bonded filter screen to prevent the filter screen from being blocked and the effect from being reduced due to too much dust.
Description
technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a dust suction and dust removal device and system used in coal mine operations in a limited space. Background technique [0002] A large amount of dust will be produced in the process of coal mining, which not only pollutes the environment, but also seriously affects the health of coal miners. Coal mine workers have become a high-risk group susceptible to pneumoconiosis. The dust removal measures in the prior art mainly adopt two kinds of low-pressure spray and high-pressure spray. Low-pressure spray dust removal has low water pressure, wastes water resources, cannot effectively reduce coal dust with small particles, and has an efficiency of less than 70% for respirable dust; Spraying in coal mines consumes a lot of water resources, and the effect is not very good. It cannot completely remove the fine particles, and it is not conducive to the discharg...
