Novel wet dust collector for mine

Abstract

The invention relates to a novel wet dust collector for a mine. The novel wet dust collector comprises a rack, a blower, a dust collector box body, a filtering tank and bolts, wherein an elbow is arranged at one end of the blower; a sewage outlet is formed in the bottom of the dust collector box body; an atomizing nozzle device, a dust collecting screen board, a first mounting board, a water-vapor separating board group and a second mounting board are sequentially arranged in the dust collector box body from the blower to an air outlet; a high-pressure water pipe is arranged on the filtering tank; and one end of the high-pressure water pipe is connected with the atomizing nozzle device. The novel wet dust collector for the mine has the characteristics of high dust control, collection and removal efficiencies, and is low in probability of blockage, low in water consumption and suitable for working in a narrow stone drift or half-coal rock roadway.

Description

technical field [0001] The invention relates to a dust collector, in particular to a novel mine wet dust collector. Background technique [0002] On the fully mechanized excavation face of the coal mine, during the excavation operation of the roadheader, coal and rocks are broken during excavation, forming a large amount of dust. The diffuse dust seriously threatens the health of coal miners, and the incidence of pneumoconiosis is significantly higher than other industries. However, even after the measures of internal and external spraying are taken, the working conditions of the tunneling face still have not changed substantially. The dust concentration at the driver of the roadheader is still as high as 500-700mg / m3, and the concentration of respirable dust can reach 150mg / m3. In some coal mines It even reaches above 1400mg / m3. The working conditions of the excavation face are very severe. According to statistics, there are currently more than 600,000 pneumoconiosis pati...

Problems solved by technology

[0004] However, the mine-used wet dust collectors in the prior art have low dust removal efficiency and poor effect, and are prone to clogging during use. Due to the low structural limitations of the roadways of thin coal seam and semi-coal rock roadways, the volume structure of the dust collector is not suitable, etc.
