[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present utility model provides a desulfurized flue gas emission device, which has the following beneficial effects:

[0019] (1) The present utility model adopts a shaft tube and a connecting tube. When actually using the desulfurized flue gas emission device, by using the control panel, open and close the two groups of solenoid valves on the left side. The desulfurized flue gas can enter the interior of the emission cylinder through the smoke inlet pipe, and then the desulfurized flue gas is discharged through the smoke outlet pipe. When it is necessary to clean the interior of the emission cylinder, by using the control panel, close the two groups of solenoid valves on the left side, and then open and close the one group of solenoid valves on the right side. The cleaning water can enter the interior of the emission cylinder through the liquid inlet pipe. When the amount of the discharged cleaning water reaches the expected value, by using the control panel, make the air pump and the driving motor work.

The rotating driven gear can drive the shaft tube to rotate. The rotating shaft tube can drive multiple groups of jet pipes to rotate. The air pump can pump air into the interior of the shaft tube through the air guide pipe. The air inside the air guide pipe can be ejected through multiple groups of jet pipes. The ejected air can drive the cleaning water to impact the inner wall of the emission cylinder. This operation can make the adsorbed substances on the inner wall of the emission cylinder fall off. The multiple groups of one-way valves and multiple groups of pressure valves can prevent the cleaning water from entering the interior of the shaft tube through the multiple groups of jet pipes. By setting the shaft tube and the connecting tube, the cleaning work of the adsorbed substances can be completed without the cleaning structure contacting the inner wall of the emission cylinder, reducing the input cost of the desulfurized flue gas emission device.

[0020] (2) The present utility model adopts a three-way pipe and a filter box. According to the above operation, it can be known that the air can be ejected through multiple groups of jet pipes. The cleaning water and the adsorbed substances can enter the interior of the connecting tube through the liquid inlet holes. The cleaning water and the adsorbed substances then enter the interior of the two filter chambers through the sleeve and the three-way pipe. The two inclined filter meshes can retain the adsorbed substances. The cleaning water can pass through the two inclined filter meshes, and finally the cleaning water is discharged through the two drain pipes. When it is necessary to clean the adsorbed substances, close one group of control valves, and then pull out one group of sealing plugs on the same side. The adsorbed substances on the upper part of the inclined filter mesh on the same side can be cleaned through one group of cleaning ports on the same side. At the same time, the other filter chamber continues to carry out the filtering work. For the cleaning of the other inclined filter mesh, by the same operation, it can be obtained that the two inclined blocks play a role in guiding the cleaning water. By setting the three-way pipe and the filter box, the cleaning work of the impurities in the waste liquid can be completed without stopping the waste liquid collection work, improving the waste liquid collection efficiency of the desulfurized flue gas emission device.

[0037] In one embodiment, the upper end of the connecting pipe 4 is of a sealed structure.

[0038] Working principle:

[0039] When actually using the desulfurized flue gas emission device, by using the control panel to open and close the two groups of solenoid valves on the left side, the desulfurized flue gas can enter the interior of the emission cylinder 1 through the smoke inlet pipe 12, and then the desulfurized flue gas is discharged through the smoke outlet pipe 13. When it is necessary to clean the interior of the emission cylinder 1, by using the control panel, close the two groups of solenoid valves on the left side, and then open and close the one group of solenoid valves on the right side. The cleaning water can enter the interior of the emission cylinder 1 through the liquid inlet pipe 14. When the discharge amount of the cleaning water reaches the expectation, by using the control panel, make the air pump 16 and the drive motor 17 work. The output end of the drive motor 17 drives the main gear 19 to rotate. Since the main gear 19 meshes with the driven gear 20, the rotating main gear 19 can push the driven gear 20 to rotate. The rotating driven gear 20 can drive the shaft tube 3 to rotate. The rotating shaft tube 3 can drive multiple groups of air jet pipes 22 to rotate. The air pump 16 can suck air into the interior of the shaft tube 3 through the air guide pipe 18. The air inside the air guide pipe 18 can be ejected through multiple groups of air jet pipes 22. The ejected air can drive the cleaning water to impact the inner wall of the emission cylinder 1. This operation can make the adsorbed substances on the inner wall of the emission cylinder 1 fall off. Multiple groups of one-way valves 24 and multiple groups of pressure valves 23 can prevent the cleaning water from entering the interior of the shaft tube 3 through multiple groups of air jet pipes 22. Through the arranged shaft tube 3 and the connecting pipe 4, the cleaning work of the adsorbed substances can be completed without the cleaning structure contacting the inner wall of the emission cylinder 1, reducing the input cost of the desulfurized flue gas emission device. At the same time, according to the above operation, it can be known that the air can be discharged through multiple groups of air jet pipes 22. The cleaning water and the adsorbed substances can enter the interior of the connecting pipe 4 through the liquid inlet hole 25. The cleaning water and the adsorbed substances then enter the interior of the two filter chambers 9 through the sleeve 6 and the three-way pipe 7. The two inclined filter meshes 26 can retain the adsorbed substances. The cleaning water can pass through the two inclined filter meshes 26. Finally, the cleaning water is discharged through the two drain pipes 30. When it is necessary to clean the adsorbed substances, close one group of control valves 31, and then pull out one group of sealing plugs 29 on the same side. The adsorbed substances on the upper part of the inclined filter mesh 26 on the same side can be cleaned through one group of cleaning ports 28 on the same side. At the same time, the other filter chamber 9 continues to carry out the filtering work. For the cleaning of the other inclined filter mesh 26, by the same operation, it can be obtained that the two inclined blocks 27 play a role in guiding the cleaning water. Through the arranged three-way pipe 7 and the filter box 8, the cleaning work of the impurities in the waste liquid can be completed without stopping the waste liquid collection work, improving the waste liquid collection efficiency of the desulfurized flue gas emission device.
