The inner frame 2 is vertically installed inside the cylinder 1, and divides the inside into a left chamber and a right chamber. The gas inlet 6 is arranged at the lower part of the cylinder body 1, and the gas outlet 5 is arranged at the upper part of the cylinder body 1. Saturated coal gas firstly passes through a coal gas inlet 6 of the device, enters the cylinder body 1 and then begins to spread, slowly rises to one side of the internal frame 2 along with the accumulation of the coal gas, flows through the water removal assembly and reaches the other side of the internal frame, and the purpose of separating water is achieved.
The baffle plate 4 is vertically installed on the inner frame 2, and a layer of silk screen is respectively installed on the front surface and the rear surface of the baffle plate 4 to cover the baffle plate 4.
