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 comprises a primary dust removal device, a secondary dust removal device, a tertiary dustremoval device, a sedimentation filter pool and a water receiver, wherein the primary dust removal device comprises a primary dust removal outer cylinder, an air intake cylinder and a rotary dust removal mechanism; an air intake grid is disposed at an inlet of the air intake cylinder; the rotary dust removal mechanism comprises a primary dust removal inner cylinder, a turbofan, a water mist spraying mechanism and a rotary power transmission mechanism; the secondary dust removal device comprises a secondary dust removal outer cylinder, a secondary dust removal inner cylinder and a guide plate;the tertiary dust removal device comprises a tertiary dust removal cylinder, a corona electrode, a filter bag type dust collector and a rectifying power supply; the filter bag type dust collector comprises a dust removal framework and a dust removal filter bag; the dust removal framework is grounded; a back-blowing pipe is disposed inside the tertiary dust removal cylinder; and the back-blowing pipe is provided with a plurality of pulse back-blowing valves. The mine dust removal system disclosed by the invention is novel and reasonable in design, convenient to implement, capable of efficientlyremoving underground mine dust and reducing harm to human beings, strong in practicability, good in use effect and convenient to popularize 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
