Adhesive dust collection system for dust removal in coal mine excavation working face

Abstract

The invention discloses a gluing dust capture system for coal mine driving face dust removal. The gluing dust capture system comprises a ventilation power subsystem, a gluing dust capture subsystem and a control subsystem; the gluing dust capture subsystem comprises a dust removal chamber, a glue spraying device, a glue spraying pump, a water spraying device, a water spraying pump and a dust removal filtering net boom, and dust capture gluing agents are evenly coated on the dust removal filtering net boom; the gas outlet end of the ventilation power subsystem is in fluid communication connection with the gas inlet end of the dust removal chamber, and the gas outlet end of the dust removal chamber is in fluid communication with atmosphere; and the dust removal filtering net boom is arranged in the dust removal chamber, the gas inlet end and the gas outlet end of the dust removal chamber are arranged on the two sides of a grid mesh of the dust removal filtering net boom, and gas flowing to the gas outlet end of the dust removal chamber from the gas inlet end of the dust removal chamber passes through the grid mesh of the dust removal filtering net boom. In this way, dust in dust air flow can be efficiently removed, the structure is simple, operation is convenient, and the phenomenon that humidity is too high due to mist spraying for dust fall can be reduced.

Description

technical field [0001] The invention relates to the field of coal mine mining, in particular to an adhesive dust collection system for dust removal on coal mine excavation working faces. Background technique [0002] Underground coal mine dust removal is a systematic project. The country has always attached great importance to the prevention and control of coal mine dust. Underground coal mines mainly adopt dust removal measures such as ventilation and dust removal, coal seam water injection, and spray dust reduction, but the dust removal effect is insufficient. Coal mine excavation working face is an important place where dust is generated. Dust removal in this place can effectively control the incidence of occupational diseases. Adhesive dust capture method is a new type of dust removal method. The dust net captures the free dust in the air and completely removes it, and prevents secondary dust. Contents of the invention [0003] In view of this, the present invention i...
