The material falls out from the end of the conveyor 1, and dust is lifted when the material falls out, and air containing dust is pumped away under the action of the air pump 12. The top of discharge hopper 2 is equipped with dust filtration case 3, and dust filtration case 3 seals the upper portion opening of oblique stub bar, forms water storage cavity 6 in the dust filtration case 3, and the bottom of dust filtration case 3 is equipped with intake pipe 11, intake pipe 11 and discharge hopper 2 intercommunication, dust enter into the cavity 8 of dust filtration case 3 lower floor along with the air from intake pipe 11 together, and the air in the cavity 8 of lower floor is again from falling in the cavity 8 of U-shaped pipe 10 upwards flow entering upper strata.

The air is not subjected to a continuous upward buoyancy during its movement from the lowermost chamber 8 to the uppermost chamber 8. When the transition is made from the adjacent cavities 8 to the upper cavity 8, the upward initial speed of the air is zero or negative, so that the upward initial speed of the air is reduced, the time length of the air moving in the water is increased, and the water is promoted to adsorb dust in the air. The lower part in the water storage cavity 6 is filled with water, the upper part is filled with air, and the air is retained in the water storage cavity 6, so that dust in the air is promoted to be adsorbed in the water. Although the air occupies the space in the water storage cavity 6, due to the blocking effect of the inverted U-shaped pipe, the liquid in the water storage cavity 6 is not connected, the hydraulic pressure of the liquid in the cavity 8 is reduced, the air is easily discharged into the cavity from the inverted U-shaped pipe 10 or the air inlet pipe 11, and under the condition that the air pump 12 with the same power is adopted, more air can be pumped into the dust filtering box 3, and the air filtering efficiency is improved.

Specifically, the cavity 8 at the uppermost layer is communicated with a water inlet pipe 14, and the cavity 8 at the lowermost layer is communicated with a water outlet pipe 15; the adjacent two cavities 8 are connected with each other through a communication pipe 16, the communication pipe 16 comprises a U-shaped pipe 17 and a drainage pipe 18, the cavity 8 located on the next layer is communicated with the U-shaped pipe 17, the other end of the U-shaped pipe 17 is communicated with the drainage pipe 18, the drainage pipe 18 is communicated with the cavity 8 on the previous layer, and the length of the U-shaped pipe 17 is greater than that of the drainage pipe 18. Water is supplied into the dust filter box 3 through the water inlet pipe 14, and newly added water first enters the uppermost chamber 8. When the liquid level in the chamber 8 is higher than the height of the drainage tube 18, the water in the chamber 8 enters the drainage tube 18, then enters the drainage pipe 15 along the drainage tube 18, and finally enters the chamber 8 of the next layer from the U-shaped pipe 17. When air is injected into the cavity 8, the air pressure in the cavity 8 is increased, so that the liquid level at one end, connected with the drainage tube 18, in the U-shaped tube 17 is pressed to be increased, but the length of the U-shaped tube 17 is greater than that of the drainage tube 18, so that the pressure for pressing water in the cavity 8 at the next layer into water at the previous layer is too high, and the air is prevented from entering the cavity 8 at the previous layer from the U-shaped tube 17 and the drainage tube 18.
Optionally, water is added into the uppermost cavity 8 through the water inlet pipe 14 while the air flows upwards to filter the dust, and water is continuously changed while the dust is filtered.

When the water in the upper cavity 8 is discharged from the inverted siphon 21, one end of the inverted siphon 21 is arranged at the bottom of the cavity 8, so that the water at the bottom of the cavity 8 can be discharged, and sediments such as waste residues at the bottom of the cavity 8 can be discharged downwards layer by layer and finally discharged from the drain pipe 15. When the liquid level in the upper layer of cavity 8 is lower than the height of the air hole 22, air enters the inverted siphon pipe 21 from the air hole 22, so that the siphon effect is broken, and the water in the upper layer of cavity 8 stops flowing to the water in the lower layer of cavity 8.
