A hydraulic punching coal water gas separator

Abstract

The invention discloses a hydraulic punching coal-water-gas separator, which relates to the technical field of mine safety, and comprises a separation barrel, a separation barrel cover is installed on the top of the separation barrel, and a water slag gas inlet and a water slag gas inlet are respectively arranged on both sides of the upper surface of the separation barrel cover. Gas outlet; a water slag separation screen is installed on the upper side of the separation barrel, the left side of the water slag separation screen is higher than the right side, and a slag discharge port is set above the right side of the water slag separation screen; a water slag separation screen is installed below the water slag separation screen. The slag filter screen is provided with a cutout hole on the upper left side of the water slag filter screen, and a drain hole is provided at the bottom of one side of the separation bucket; a first hammer block is provided under the water slag separation screen, and a second Two hammer blocks, the drive system drives the first hammer block and the second hammer block to hammer and vibrate the water slag separation screen and the water slag filter screen respectively. The invention can separate, discharge and collect gas, water, cinder and other mixtures, effectively avoid the problem of gas overrun caused by spray holes, and also improve the space environment of the drilling site.

Description

technical field [0001] The invention relates to the technical field of mine safety, in particular to a hydraulic punching coal-water gas separator. Background technique [0002] With the continuous increase of mine mining depth, coal and gas outbursts are becoming more and more serious. In order to solve related problems, the best way at this stage is to use hydraulic punching technology. The high-pressure water impacts the coal body around the drilling hole through the high-efficiency nozzle, rushing out a large amount of coal body and gas, and the stress concentration moves to the surrounding of the punching hole, which relieves the pressure of the coal body near the drilling hole and increases the permeability, effectively improving the drainage effect. [0003] In the prior art, the key points of the anti-conflict measures are firstly to pump out a large amount of gas between and after punching holes; secondly, to be able to flush out a considerable amount of coal to for...
