Support coal-discharging-port negative-pressure atomizing dust settling device

Abstract

The invention relates to a support coal-discharging-port negative-pressure atomizing dust settling device. One end of a U-shaped body is closed, one end of the U-shaped body is opened, the closed end is connected with an air suction port, and the air suction port is communicated with a cavity of the U-shaped body; the air suction port is vertical to the U-shaped body. One end of an air induced pipe is closed, one end of the air induced pipe is opened, the opened end of the U-shaped body is connected with the opened end of the air induced pipe through a flange into a whole; the cavity, close to the closed end, of the air induced pipe is communicated with the cavity of a jet air induced body. Two air induced pipes are arranged inside the jet air induced body in a fan shape. The support coal-discharging-port negative-pressure atomizing dust settling device has the beneficial effects that by adopting the arrangement form of the air induced pipes, the negative pressure is produced through the high-pressure water mist, and the dust produced in a rear coarse of a fully mechanized caving face can be purified; a high-speed water-mist eddy field is produced through the high-pressure water-mist spraying-absorption phenomenon, and the high-speed water-mist eddy field right covers a coal discharging port; the atomizing efficiency is good, the dust-removal efficiency is high, and the dust drift route can be effectively covered and blocked; by adopting a U-shaped rotary structure, a quick coupling is adopted for a pipeline interface; the support coal-discharging-port negative-pressure atomizing dust settling device has the advantages of reasonability in structure, light weight, convenience in installation and application and the like.

Description

technical field [0001] Mine equipment dust removal field. Background technique [0002] A large amount of dust is produced during the coal caving process, which is one of the main dust sources constituting the top coal caving face. The existing dust control technology in the coal caving process of the top coal caving face mainly adopts the method of installing nozzles on the hydraulic support and not the tail beam to carry out spray dust suppression. Because the water source used in this method is low-pressure natural water, the atomization effect is poor, and the water mist cannot effectively interact with the dust and then condense and land; second, the installation location is unreasonable and cannot effectively cover the dust-producing point, and the water mist cannot effectively block The flow and escape of dust, the third is the shortcoming of the low-pressure nozzle itself, which is easy to block and has a low service life. Therefore, the dust generated during the co...

Problems solved by technology

Because the water source used in this method is low-pressure natural water, the atomization effect is poor, and the water mist cannot effectively interact with the dust and then condense and land; second, the installation location is unreasonable and cannot effectively cover the dust-producing point, and the water mist cannot effectively block The flow and escape of dust, the third is the shortcoming of the low-pressure nozzle itself, which is easy to block and has a low service life. Therefore, the dust generated during the coal discharge process escapes through the racks of the racks to the pedestrian space in front of the racks. The concentration is far greater than the national standard, which is harmful to the health of workers serious impact on the health and safety of the working environment
