A mine dry dust collector

Abstract

The invention discloses a high-efficiency and low-consumption dry dust collector for mining. The dry dust collector comprises a dust collecting box body, an air inlet cylinder and an air exhaust cylinder, wherein the dust collecting box body is internally provided with a speed reducing cavity, a filtering cavity, an air purifying cavity and a dust collecting cavity, the speed reducing cavity communicates with the air inlet cylinder, the filtering cavity communicates with the speed reducing cavity, a plurality of filtering cylinders are arranged in the filtering cavity, the air purifying cavityis arranged above the filtering cavity, the top of each filtering cylinder is open and extends into the air purifying cavity, the air exhaust cylinder communicates with the air purifying cavity, an air inducing device is arranged in the air exhaust cylinder, and the dust collecting cavity is formed in the bottom of the filtering cavity and directly communicates with the filtering cavity. The drydust collector has the advantages that the dust collection efficiency reaches 99.5%, and the dry dust collector can be widely applied to working surfaces such as coal mine driving, transfer and guniting, has the characteristics of low energy consumption, zero water consumption, no pollution and the like, reaches the standard of the mine dust concentration, achieves the dust-free mine construction,and is especially suitable for arid and water-deficient areas.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a mine dry dust collector. Background technique [0002] On the working face of the coal mine, during the mining operation of the fully mechanized excavator, coal and rocks are broken during the excavation, forming a large amount of dust. A large amount of dust will also be generated at the place where the coal is dropped by the coal shearer and the belt conveyor. The diffuse dust seriously threatens the health of coal miners, and the incidence of pneumoconiosis is significantly higher than other industries. Therefore, a dust collector must be used in the mine production process to absorb and purify the coal dust air in the mine environment and then discharge it. [0003] At present, most mine dust collectors use wet dust collectors, which make the dusty gas and liquid (usually water) in close contact, and use the inertial collision of water droplets and particle...
