A mine dust removal system and dust removal method thereof

Abstract

The invention discloses a mine dust removal system and a dust removal method thereof. The dust removal system includes a first-level dust removal device, a second-level dust removal device, a third-level dust removal device, a sedimentation filter tank and a water storage device; the first-level dust removal device includes a first-level dust removal device cylinder, air intake cylinder and rotary dust removal mechanism, the inlet of the intake cylinder is provided with an air intake grid; the rotary dust removal mechanism includes a first-level dust removal inner cylinder, a turbo fan, a water mist injection mechanism and a rotary power transmission mechanism; the second stage dust removal device includes The secondary dust removal outer cylinder, the secondary dust removal inner cylinder and the deflector; the tertiary dust removal device includes the tertiary dust removal cylinder, the corona electrode, the filter bag dust collector and the rectified power supply, and the filter bag dust collector includes the dust removal skeleton and the dust filter The bag, the dust removal framework is grounded, and the three-stage dust removal cylinder is equipped with a blowback pipe inside, and multiple pulse blowback valves are arranged on the blowback pipe. The invention is novel and reasonable in design, convenient in realization, capable of efficiently removing underground dust in mines, reducing harm to human beings, strong in practicability, good in use effect, and convenient for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of mine dust removal, and in particular relates to a mine dust removal system and a dust removal method thereof. Background technique [0002] With the increase of my country's demand for coal energy, the number of coal mines has gradually increased, and the dust hazard has become the most serious hazard in the coal industry. At present, the dust prevention measures of most coal mines in my country cannot achieve the purpose of effective dust prevention, or even have no dust prevention measures. The serious consequence is that the hidden danger of coal dust explosion increases, especially the number of people with coal mine pneumoconiosis increases year by year. [0003] The mine dust removal measures in the prior art can be divided into five categories: reduction, reduction, discharge, removal and resistance. (1) Dust reduction: spraying water, wet drilling, wet spraying and water seal blasting on the fac...

AI Technical Summary

Problems solved by technology

Although wet dust removal is small in size, simple and easy to operate, and has low equipment costs, most wet dust collectors have small air volume, poor atomization, and low dust removal efficiency; dry dust removal has higher efficiency, does not consume water, and has a high degree of automation. The amount of daily maintenance is small, and the labor intensity of workers is low. However, the dry dust collector is bulky and inconvenient to move. It cannot be used in the excavation roadway with limited space. The filter bag will stick to the bag when it encounters water, which will affect the dust removal efficiency.

In the prior art, there is still a lack of mine dust removal systems and methods whose dust removal effect meets actual needs
