In this embodiment, when the adsorption liquid circulates, the second control valve 422 located at the position of the forward flow pipeline 41 and the filter pipeline 42 and the position of the second control valve 422 are in a closed state, and the third control valve 432 located at the position of the connection between the filter pipeline 42 and the reverse flow pipeline 43 is also in a closed state, at this time, the adsorption liquid entering the first suction pump 411 starts to convey the adsorption liquid in the first filter cavity 2 to the forward flow pipeline 41, and when the liquid enters the filter pipeline 42, the adsorption liquid cannot enter the collection tank 44 connected to the bottom of the filter pipeline 42 during the blocking of the second control valve 422, and can only move unidirectionally along the filter pipeline 42 under the action of the first suction pump 411, so as to ensure that the liquid is filtered through the inclined filter plate 421, and when the adsorption liquid moves to the bottom of the filter pipeline 42, the blocking of the connection position of the reverse flow pipeline 43 and the filter pipeline 42 enables the adsorption liquid to flow unidirectionally into the second filter cavity 3, so as to complete the circulating movement of the adsorption liquid. When the filter pipeline 42 needs to be flushed, the first suction pump 411 stops working, at this time, the second control valve 422 and the third control valve 432 are all opened, at this time, the adsorption liquid in the first filter cavity 2 and the second filter cavity 3 does not enter the filter pipeline 42, the second suction pump 431 starts to suck the liquid in the circulating water cavity 4, the liquid in the circulating water cavity 4 flows to the top of the filter pipeline 42 along the countercurrent pipeline 43 under the suction of the second suction pump 431, and enters the filter pipeline 42 from top to bottom through the third control valve 432 at the top of the filter pipeline 42 to flush the inclined filter plate 421, impurities carrying on the inclined filter plate 421 flow to the bottom of the filter pipeline 42, and because the positive flow pipeline 41 is horizontally connected to the side surface of the filter pipeline 42, the liquid flowing from top to bottom directly enters the collecting box 44 through the second control valve 422 at the bottom of the filter pipeline 42 under the action of gravity, the second control valve 422 and the third control valve 432 can be electromagnetic valves or ball valves, and the change of the on-off states of the second control valve 422 and the third control valve 432 can realize different working states in the filter pipeline 42, and ensure that the working states of the liquid in the filter pipeline 42 and the first filter cavity 2 and the second filter cavity 4 and the circulating liquid in the filter cavity 4 can not coincide with each other. Because the second control valve 422 is kept closed when the adsorption liquid in the first air filtering cavity 2 and the second air filtering cavity 3 circularly flows, the collecting box 44 in the circulating water cavity 4 can be independently pulled out when the system works, and the normal work of the equipment can not be influenced when the staff cleans the impurities in the collecting box 44, so that the working efficiency is improved.
Referring to fig. 7: the output end of the liquid passing pipe 32 is provided with a first control valve 321.
In this embodiment, when the adsorption liquid in the first air filtering cavity 2 and the second air filtering cavity 3 flows, the second control valve 422 and the third control valve 432 are closed, and when the second control valve 422 and the third control valve 432 are opened, the first control valve 321 at the output end of the liquid through pipe 32 is closed, at this time, the liquid in the first air filtering cavity 2 flows into the second air filtering cavity 3 under the suction of the first suction pump 411, the adsorption liquid in the second air filtering cavity 3 flows into the first air filtering cavity 2 through the liquid through pipe 32, when the unit flow rate of the liquid through pipe 32 is the same as the unit flow rate of the liquid in the positive flow pipe 41, the amount of the adsorption liquid in the first air filtering cavity 2 and the second air filtering cavity 3 is kept stable, and when the second control valve 422 and the third control valve 432 are opened, the first control valve 321 is closed, the adsorption liquid in the first air filtering cavity 2 is prevented from continuously entering the first air filtering cavity 2 by the liquid through pipe 32, so that the content of the adsorption liquid in the first air filtering cavity 2 and the second air filtering cavity 3 is kept unchanged, and the content of the adsorption liquid in the second air filtering cavity 3 is ensured, and the impurity in the air filtering cavity 2 and the air inlet pipe 21 and the air in the air filtering cavity 42 can be cleaned normally, and the impurity in the air filtering cavity 42 can not be cleaned.
The foregoing examples merely illustrate one or more embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
