When the invention is used, firstly, water is added into the container 1 to raise the liquid level in the container 1 until the liquid level in the container 1 reaches the inner side bending structure of the inverted U-shaped structure position of the drain pipe 6', and when the drain pipe 6' starts draining, the water is stopped to be continuously added into the container 1, and the inverted siphon phenomenon of the drain pipe 6 'is generated when the drain pipe 6' drains water due to the gas stored in the inverted U-shaped structure position of the drain pipe 6', namely, until the water level in the container 1 outside the drain pipe 6' is lower than the pipe orifice of the drain pipe 6', so that the gas in the container 1 is communicated with the gas stored in the inverted U-shaped structure position through the drain pipe 6', thereby stopping the inverted siphon phenomenon of the drain pipe 6', and the drain pipe 6' stops draining; the granular medium 7 in the container 1 has now been wetted with water. If the pipeline A5 is communicated with the air inlet end of the fan, the uncleaned gas directly contacts the wetted particle medium 7 from the opening of the container 1, and is discharged through the pipeline A5 after being purified by the wetted particle medium 7, so that the purified gas can be discharged for a certain designated area, and the gas passing through the fan is purified at the moment; if the pipeline A5 is communicated with the air outlet end of the fan, the unpurified gas contacts the wet granular medium 7 in the container 1 through the pipeline A5, and is directly discharged through the opening of the container 1 after being purified by the wet granular medium 7, so that the unpurified gas in a certain designated area can be sucked and removed, the purified gas discharged through the opening of the container 1 can be more uniform, the gas passing through the fan is the unpurified gas, and the fan needs to be periodically cleaned.
When the granular media 7 absorb more dirt, water is added into the container 1 again, so that the liquid level in the container 1 rises, and when the liquid level in the container 1 reaches the inner side bending structure at the position of the inverted U-shaped structure of the drain pipe 6', and when the drain pipe 6' starts draining, the water is stopped from being continuously added into the container 1, and due to the inverted siphon phenomenon generated during draining of the drain pipe 6', the water in the container 1 is automatically drained until the liquid level is lower than the pipe orifice of the drain pipe 6', and the water is stopped from being continuously drained. The wetted granular media 7 with the purifying function is concentrated at the position of the air hole 8, so dirt is also concentrated on the surface of the wetted granular media 7 at the position of the air hole 8, and because the inner bending structure at the position of the inverted U-shaped structure of the drain pipe 6' is higher than the air hole 8 at the highest position on the pipeline A5, water is added into the container 1 again, and when the liquid level in the container 1 reaches the inner bending structure at the position of the inverted U-shaped structure of the drain pipe 6', the dirt adsorbed on the surface of the wetted granular media 7 at the position of the air hole 8 is immersed in the water, and then the dirt is discharged together with the water by the inverted siphon action of the drain pipe 6 '; thereby effecting cleaning of the particulate medium 7.
