[0002] Coal mine gas and dust accidents are one of the major disasters underground. Eliminating gas overrun and dust is a prerequisite for preventing gas and dust accidents and an important guarantee for the safe production of mines.
[0003] Due to geological sedimentation, a large amount of toxic and harmful gases such as gas are accumulated in the coal seam. In order to achieve safe mining, usually, special gas drainage tunnels are arranged first before mining, and drainage boreholes are constructed by tunnel drilling rigs to implement gas drainage in advance.

The exhaust pipe 4 is vertically arranged. A feed pipe 5 and a drain pipe 6 are fixedly communicated with the side wall of the separation barrel 1. The feed pipe 5 is located above the drain pipe 6. A slag discharge hole 10 is formed in the side wall of the separation barrel 1. The slag discharge hole 10 and the feed pipe 5 are symmetrically arranged on both sides of the separation barrel 1. The slag discharge hole 10 is located between the feed pipe 5 and the drain pipe 6. The bottom end of the slag discharge hole 10 is flush with the top end of the filtering mechanism. A cleaning mechanism is fixedly communicated with the side wall of the separation barrel 1. The cleaning mechanism is located between the slag discharge hole 10 and the feed pipe 5. The drain pipe 6 is located between both ends of the cleaning mechanism.
[0024] Through the arranged feed pipe 5, the gas-water-slag mixture can be introduced into the separation barrel 1. The gaseous substance is discharged from the separation barrel 1 through the exhaust pipe 4 to be separated from the water-slag mixture. The water-slag mixture falls on the filtering mechanism for filtration to realize the separation of water and slag. The water falls to the bottom of the separation barrel 1 while the slag remains on the filtering mechanism. The rotating part drives the filtering mechanism to rotate continuously, so that the separated slag is discharged from the slag discharge hole 10. When a certain amount of water accumulates in the separation barrel 1, it overflows through the drain pipe 6. The cleaning mechanism can use the water remaining in the separation barrel 1 to clean the filtering mechanism to prevent the filtering mechanism from being blocked.
