A wet orifice eddy current collection and control device and method

Abstract

A wet orifice vortex collection and dust control device and method are applicable to the prevention and control of dust produced by various boreholes in underground coal mines through compressed air and slag discharge. The wet orifice vortex collection and control device consists of a dust collector front cover, a dust collector rear cover, a drilling casing, a centralized slag discharge pipe, a vortex dust discharge pipe, a Venturi jet ejector and a high-pressure water nozzle; In the wet orifice vortex collection and dust control method, firstly, a drilling rig constructs a shallow hole on the wall of the coal rock mass and inserts the drilling casing, the wet orifice vortex collection and dust control device is suspended and fixed through the suspension ring, and the high-pressure water nozzle is turned on. And maintain the normal operation of the spray during the drilling process, insert the drill pipe through the drill pipe entrance and implement the drilling. The invention has compact structure and convenient operation, which is beneficial to the centralized collection and regular discharge of drilling slag, avoids the escape of dust-laden air from the entrance of the drill pipe, realizes two purifications of dust-laden air, and improves the dust removal efficiency.

Description

technical field [0001] The invention relates to a wet orifice eddy current collecting and controlling device and method, which is especially suitable for collecting and preventing dust generated by compressed air and slag discharge during underground drilling in coal mines. Background technique [0002] Most of the underground coal mine operations are accompanied by the generation of a large amount of dust, especially in the construction of underground gas drainage drilling. The use of compressed air to discharge slag causes a large amount of dust to escape in the drilling space, making the dust pollution in the drilling operation site extremely serious, directly endangering the safe production of the coal mine and the physical and mental health of the workers. Up to now, how to implement simple and effective prevention and control of drilling dust and improve the working environment of drilling workers has always been a difficult problem to be solved at the construction sit...
