[0020] As Figure 1 shown, in this embodiment Figure 1This is a multi-stage dust removal device for waste gas of the present utility model, including a filtering pipeline 1 and a dust collection pipeline 9, where:
[0021] One end of the filtering pipeline 1 is connected to the dust waste gas port 2, and the other end of the filtering pipeline 1 is communicated with the air inlet 4 on the first dust removal tank 3. A first filtering device 5 is arranged in the filtering pipeline 1. A dust removal pipeline 6 is arranged on the first dust removal tank 3, and the other end of the dust removal pipeline 6 is connected to the second dust removal tank 7. An exhaust port 8 is arranged on the second dust removal tank 7. One end of the dust collection pipeline 9 is arranged in the second dust removal tank 7, and the other end thereof is connected to the dust collection system 10.
[0022] A water outlet pipeline 12 is arranged in the first dust removal tank 3. A plurality of spray heads are arranged on the water outlet pipeline 12. One place of the water outlet pipeline 12 is provided with a water inlet 14, and the water inlet 14 extends outside the first dust removal tank 3 through an opening on the first dust removal tank 3. A water connection pipe 15 is connected to the water inlet 14, and one end of the water connection pipe 15 is communicated with the circulating water system 16.
[0023] A filter plate 13 is arranged in the first dust removal tank 3. An opening is arranged on the filter plate 13, and one end of the dust removal pipeline 6 penetrates through the opening of the filter plate 13 and extends to the inside of the first dust removal tank 3.
[0024] A dust removal filter bag 17 is arranged inside the second dust removal tank 7. The top end of the dust removal filter bag 17 is communicated with the dust removal pipeline 6.
