Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 In order to solve the problem that uneven desulfurization agent spraying may lead to insufficient desulfurization agent spraying in some areas, while excessive desulfurization agent spraying in other areas may make the contact area between the desulfurization agent and the flue gas uneven, thereby affecting the desulfurization efficiency, the following preferred technical solutions are provided:

[0021] A cleaning structure for a flue gas dust removal and desulfurization tower, comprising a cleaning box 2 installed on one side of a desulfurization tower 1, a water pump body 3 installed on the upper end of the cleaning box 2, the cleaning box 2 is used to store a desulfurizer, an output end of the water pump body 3 is connected to an output pipe 4, an outer wall of the output pipe 4 is installed with a control valve 5, an end of the output pipe 4 away from the water pump body 3 is fixedly connected to a nozzle body 6, one end of the nozzle body 6 is connected to a spray pipe A7, both sides of the spray pipe A7 are connected to spray pipes B8, and the spray pipe A7 and the spray pipe B8 are connected. A flow hole 9 is opened at the lower end, multiple groups of spray pipes B8 are provided, and the multiple groups of spray pipes B8 are evenly arranged on both sides of the spray pipe A7, multiple groups of flow holes 9 are provided, and the multiple groups of flow holes 9 are evenly arranged on the lower walls of the spray pipes A7 and the spray pipes B8, a block body 10 is provided on the inner wall of the flow hole 9, and a sealing block 11 is fixedly connected to the lower end of the block body 10, the diameter of the block body 10 is smaller than the inner diameter of the flow hole 9, and the diameter of the sealing block 11 matches the inner diameter of the flow hole 9.

[0022] A first through groove 12 is provided on the outer wall of the block body 10, and a second through groove 13 is provided inside the sealing block 11. The upper end of the second through groove 13 is connected to the first through groove 12, and both ends of the second through groove 13 pass through both sides of the sealing block 11. Elastic elements 14 are fixedly connected to both sides of the block body 10, and one end of the elastic element 14 away from the block body 10 is fixedly connected to the inner wall of the through hole 9. When the elastic element 14 is in a state, the sealing block 11 is completely in the cavity of the through hole 9.

[0023] Specifically, when the flue gas in the desulfurization tower 1 is desulfurized and cleaned, the water pump body 3 is started, and the desulfurizer in the cleaning box 2 is introduced into the output pipe 4 by the water pump body 3, and then input into the nozzle body 6 through the output pipe 4, and then the desulfurizer is introduced into the spray pipe A7 and the spray pipe B8 through the nozzle body 6, and evenly sprayed through multiple groups of through-flow holes 9, so that the contact area between the desulfurizer and the flue gas is extremely uniform, which solves the problem that the uneven spraying of the desulfurizer will lead to insufficient desulfurizer spraying in some areas, while other areas may have excessive desulfurizer spraying, making the contact area between the desulfurizer and the flue gas uneven, thereby affecting the desulfurization efficiency. When the desulfurizer is introduced into the spray pipe A7 and the spray pipe B8, The desulfurizer will enter the first through groove 12, and then enter the second through groove 13 through the first through groove 12. At this time, the sealing block 11 is completely on the inner wall of the through hole 9, so the second through groove 13 is in a sealed state. As the desulfurizer increases, the block body 10 will drive the sealing block 11 to move gradually outward. At this time, the elastic element 14 is tightened, and the sealing block 11 will drive the second through groove 13 to disengage from the through hole 9, so the desulfurizer will flow out from the second through groove 13. After the desulfurizer input is stopped, the block body 10 will be pulled back by the elastic element 14, and the second through groove 13 will be sealed again, which can avoid the leakage of residual desulfurizer, with significant effect, and further ensure the efficiency of desulfurization and cleaning.

[0024] To sum up: start the water pump body 3, use the water pump body 3 to guide the desulfurizer in the cleaning box 2 into the output pipe 4, input it to the nozzle body 6 through the output pipe 4, and then guide the desulfurizer into the spray pipe A7 and the spray pipe B8 through the nozzle body 6. The desulfurizer will enter the first through groove 12, and then enter the second through groove 13 through the first through groove 12. At this time, the sealing block 11 is completely on the inner wall of the through hole 9, so the second through groove 13 is in a sealed state. As the desulfurizer increases, the block body 10 will drive the sealing block 11 to move outward gradually. At this time, the elastic element 14 is tightened, and the sealing block 11 will drive the second through groove 13 to disengage from the through hole 9, so the desulfurizer will flow out from the second through groove 13 and be evenly sprayed through multiple groups of through holes 9, so that the contact area between the desulfurizer and the flue gas is extremely uniform.
