The bottom end of the air outlet pipe 8 is inserted into the tail filter barrel 2 and is located above the liquid level of the water 6, and the upper end of the air outlet pipe 8 extends out of the top of the tail filter barrel 2.

[0024] Example 2

[0025] like Figure 1 As shown, a one-way valve is provided in the air inlet pipe 7 to limit the gas to flow only into the first filter barrel 1, thereby preventing the gas carrying cement dust from flowing back.

[0026] Example 3

[0027] like Figure 1As shown, the end of the U-shaped tube 4 located above the liquid surface and the end of the air outlet pipe 8 located above the liquid surface are respectively provided with an air collecting hood 5. The gas discharged from the liquid surface enters the U-shaped tube through the air collecting hood and enters the next intermediate filter barrel or the tail filter barrel for the next stage of filtration.

[0028] Example 4

[0029] like Figure 1 As shown, the bottoms of the head filter barrel 1, the middle filter barrel 3 and the tail filter barrel 2 are all integrally connected with a conical sedimentation bin 15, the bottom of the sedimentation bin 15 is connected with a sewage pipe, and the sewage pipe is provided with a first valve 16. The sedimentation bin 15 is used to settle cement in the water, and the sewage pipe is used to discharge sewage in the head filter barrel 1, the middle filter barrel 3 and the tail filter barrel 2.

[0030] Example 5

[0031] like Figure 1 As shown, the head filter barrel 1, the middle filter barrel 3 and the tail filter barrel 2 are all fixedly connected to a workbench 01. The workbench 01 includes a table top and supporting legs fixedly connected to the lower end of the table top. The sedimentation bin 15 passes through the table top and is fixedly connected to the table top. A sewage collection tank 17 is provided on the ground below the sewage pipe.

[0032] Example 6

[0033] like Figure 1 , 2 As shown, the water-type dust collector is also provided with a water supply mechanism.

[0034] like Figure 1 , 2 As shown, the water supply mechanism includes a water supply main pipe 11, which is arranged along one side of the head filter barrel 1, the middle filter barrel 3 and the tail filter barrel 2, and is connected to a nozzle 10 through a connecting pipe 20 that penetrates the side walls of the head filter barrel 1, the middle filter barrel 3 and the tail filter barrel 2.

[0039] The working principle of this new model:

[0040] The cement tank uses the dust extraction fan installed on the top to discharge the gas containing cement particles through the outlet pipe. The gas enters the first filter barrel through the air inlet pipe, enters the U-shaped tube after the first filtration, and enters the middle filter barrel through the U-shaped tube for filtration. The filtered gas enters the middle filter barrel or the tail filter barrel through the U-shaped tube again for further water filtration. During the filtration process, the cement particles are retained in the water and settle in the sedimentation bin. The clean air is finally discharged through the outlet pipe of the tail filter barrel.

[0041] After using it for a period of time, the turbidity of the water in the barrel can be checked with a flashlight. Specifically, the flashlight can be shone along two relatively transparent observation windows, and the turbidity of the water can be judged by the light transmittance of the flashlight. Furthermore, when the staff determines that sewage needs to be discharged, the sewage can be discharged through the sewage pipe, and then the third valve on the side of the high-pressure water supply device is opened, and the second valve on the connecting pipe of the filter barrel that needs to be cleaned is opened. The high-pressure water is flushed toward the barrel wall and the inner wall of the sedimentation bin through the nozzle, and the attached cement is flushed into the sewage collection tank 17. Finally, the first valve and the third valve on the side of the high-pressure water supply device are closed, the third valve on the side of the water source pipe and the second valve of the filter barrel that needs to be filled with clean water are opened, and the filter barrel is filled with water. After a certain amount of water is filled, the corresponding third valve and second valve are closed.
