Downhole ventilation pipeline with warm keeping and humidifying functions for coal mining

Abstract

The invention discloses a downhole ventilation pipeline with warm keeping and humidifying functions for coal mining. The pipeline comprises a pipeline body, a water pump, an exhaust fan, and an air supply pipe, a supporting shaft is mounted on the surface of the inner wall of the pipeline body, sliding grooves are formed in the surfaces of inner walls of the left and right sides of the pipeline body, atomizing nozzles are connected to the front surface of a water spraying plate, the exhaust fan is mounted above the left side of the pipeline body, first springs are connected to the left and right sides of a mounting block, an inner pipe is mounted in the air supply pipe, a transverse rod is mounted in the right side of the pipeline body, according to the downhole ventilation pipeline with warm keeping and humidifying functions for coal mining, the water spraying plate and the atomizing nozzles are mounted in the pipeline body, in the process of ventilation of the pipeline body, air entering the pipeline body can be conveniently humidified, in the humidifying process, dust in the air can be removed, the underground dust concentration is effectively reduced, and the underground ventilation air quality is improved.

Description

technical field [0001] The invention relates to the technical field related to coal mining, in particular to an underground ventilation pipe for coal mining with functions of keeping warm and humidifying. Background technique [0002] As a basic energy source, coal mines occupy a very important position in my country's energy structure. Coal mines are an important guarantee for the sustainable development of my country's industry. With the continuous increase in the demand for coal mines, the depth and breadth of coal mining are constantly expanding. A large amount of dust will be generated during the mining process. The ventilation system in the mine is an important part of the underground production system. In order to ensure the normal operation of the underground mining work and meet the daily air requirements of the underground, it is very important to establish a complete ventilation pipeline. Yes, but the existing underground ventilation pipes still have certain defects...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of underground ventilation pipeline with warming and humidification functions for coal mine development, to solve the above-mentioned background technology that the use of filter screen filtration requires regular disassembly and cleaning, which is not convenient for maintenance, and the inside of the pipeline generates noise due to gas flow. The tuyere is open for a long time, which will cause the inner wall of the pipeline to freeze in a cold environment, which is not conducive to the normal operation of the ventilation of the pipeline.
