Dry type filtration dust removal system for roadway driving working face

Abstract

The invention provides a dry type filtration dust removal system for a roadway driving working face. Both an extraction fan (5) and a dry type filtration dust remover (4) are fixedly installed on a support (7). The support (7) is arranged on the upper side of a belt conveyor (10) in a nested mode and installed on the upper side of a moving frame (8). The extraction fan (5) is sequentially connected with the dry type filtration dust remover (4), a negative-pressure air barrel (3) and a suction hood (2). The negative-pressure air barrel (3) is suspended on the top of a roadway (1) through a monorail crane (9). The suction hood (2) is supported on a rocker arm (13) at the rear end of a cutting head (14) in a surrounding mode. The dust removal system is high in dust removal efficiency, does not occupy independent moving power, and can operate in cooperation with a driving procedure.

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.
