A dry filter and dust removal system for roadway excavation working face

Abstract

The invention provides a dry filter and dust removal system for roadway excavation working face, in which the draw-out fan (5) and the dry filter dust collector (4) are fixedly installed on the bracket (7), and the bracket (7) is nested on the belt conveyor (10) above and installed on the mobile frame (8); the draw-out fan (5) is connected to the dry filter dust collector (4), the negative pressure air cylinder (3), and the dust suction cover (2); the negative pressure air cylinder (3) hang on the top of the tunnel (1) by a monorail crane (9); the dust suction cover (2) is supported on the rocker arm (13) at the rear end of the cutting head (14) in an encircling manner. The dust removal system has high dust removal efficiency, does not occupy a separate mobile power, and can be coordinated with the tunneling process.

Description

technical field [0001] The invention relates to a dust removal system, in particular to a dry filter dust removal system for a roadway excavation working face, which belongs to the technical field of mine roadway ventilation and safety. Background technique [0002] Excavation operations in mine roadways, ground tunnels and other similar spaces will generate a lot of dust. Dust will not only directly deteriorate the working environment and affect the normal operation of equipment, but also induce severe pneumoconiosis and even cause explosion hazards, especially in coal mine excavation work. [0003] For a long time, the coal mine excavation surface has generally been dominated by wet dust removal methods, such as spraying water for dust reduction, foam dust suppression, etc. to control the dust concentration. It is more difficult to apply to the arid and water-scarce mining areas in the west of the main production area; the dry filter dust removal technology does not consu...

AI Technical Summary

Problems solved by technology

Dust will not only directly deteriorate the working environment and affect the normal operation of equipment, but also induce severe pneumoconiosis, and even cause explosion hazards, especially in coal mine excavation.

[0003] For a long time, the coal mine excavation surface has generally been dominated by wet dust removal methods, such as spraying water for dust reduction, foam dust suppression, etc. to control the dust concentration. It is more difficult to apply to the arid and water-deficient mining areas in the west of the main production area; the dry filter dust removal technology does not consume water and has a high dust purification efficiency, especially for respirable dust. The collection efficiency is as high as 90%. The space is crowded, the process is complicated, and the dry filter and dust removal equipment is relatively large, which has always been difficult to adapt to the narrow space of the excavation work surface.
