[0005] Furthermore, the air inlet and the air outlet are arranged opposite to each other.

[0006] Furthermore, three inspection ports are provided, which are distributed up and down. The uppermost inspection port is provided on the equipment body above the demisting layer, and the middle inspection port is provided on the equipment body above the packing layer.

[0007] Furthermore, the differential pressure gauge and the backwash pipe are arranged in linkage.

[0008] Furthermore, the air inlet and the air outlet have the same diameter, which accounts for 9 / 20-1 / 2 of the inner diameter of the device body.

[0009] Beneficial effect: Compared with the prior art, the utility model has the following significant advantages: the utility model has a reasonable structure, the exhaust gas enters through the air inlet, is processed by the packing layer, and is discharged from the air outlet after passing through the demisting layer, and the demisting moisture is discharged from the sewage outlet. The differential pressure gauge and the backwashing pipe are linked together. When the demisting layer is blocked, the demisting layer can be cleaned by backwashing. The caliber of the air inlet and the air outlet is the same, which accounts for 9 / 20-1 / 2 of the inner diameter of the equipment body, and the treatment effect is good. This product more effectively guarantees the operation of the equipment at the exhaust gas front end, saves operating costs, and ensures the safe operation of the equipment. This product is safe to operate and easy to maintain, and meets actual use needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example 1

[0013] like Figure 1 and Figure 2 As shown, a backwashing demisting device described in the utility model comprises an equipment body 1, an air inlet 2 is arranged below the equipment body 1, an air outlet 3 is arranged above the equipment body 1, the air inlet 2 and the air outlet 3 are arranged opposite to each other, the air inlet 2 and the air outlet 3 have the same diameter, and the diameter accounts for 47 / 100 of the inner diameter of the equipment body 1, a packing layer 4 and a demisting layer 5 are arranged in the equipment body 1 between the air inlet 2 and the air outlet 3, the demisting layer 5 is arranged above the packing layer 4 and a spacing is left between them, and a backwashing pipe 6 is arranged below the demisting layer 5 The air inlet 2 and the air outlet 3 are connected to the two ends of the differential pressure gauge 7 through an air pipe. The differential pressure between the air inlet and the air outlet can be observed through the differential pressure gauge 7. The differential pressure gauge 7 and the backwashing pipe 6 are arranged in linkage. When the differential pressure of the differential pressure gauge 7 is too high, the demisting layer 5 can be flushed by backwashing. An inspection port 8 is provided on the side of the equipment body 1. There are three inspection ports 8, which are distributed up and down. The uppermost inspection port 8 is provided on the equipment body 1 above the demisting layer 5, and the middle inspection port 8 is provided on the equipment body 1 above the packing layer 4. A sewage outlet 9 is provided at the lower part of the equipment body 1. Example 2
