[0026] Here's how it works:

[0027] First, before use, connect the pipeline containing coalbed methane to the feed port 2 so that it can enter the shell 1 for gas-water separation;

[0028] Second, when in use, coalbed methane enters the shell 1 through the feed port 2, and is separated into gas and water by the separation plate 5. The separated gas is discharged through the exhaust port 3, and water and particulate matter fall to the bottom of the shell 1. The water is discharged through the drain port 4, and particulate matter is intercepted by the filter plate during the discharge process;

[0029] Third, after using for a period of time, it is necessary to clean the particles. The electric push rod 664 is started, so that the electric push rod 664 drives the fixed block 665 to move upward. When the fixed block 665 moves, the blocking block 661 is fixed. Then, the handle 662 is pulled to the left to move. When the handle 662 moves, the blocking block 661 is driven to move, and the gap at the bottom left end of the housing 1 is opened.

[0030] Fourth, start the motor 63, so that the motor 63 drives the screw 62 to rotate, and the screw 62 rotates and drives the movable block 64 to move, and the movable block 64 moves and drives the filter plate 65 to move, and the filter plate 65 moves and pushes the residue to move, and pushes the residue out of the housing 1;

[0031] Fifth, when the cleaning is completed, the filter plate 65 is controlled by the motor 63 to move to the left end of the drain outlet 4 to block it, and the blocking block 661 is placed in the bottom gap of the left end of the shell 1, and the electric push rod 664 is started to push the fixed block 665 downward so that the fixed block 665 extends into the blocking block 661, and the blocking block 661 is fixed, and the coalbed methane can continue to be separated from the water.
