[0002] The wet electrostatic precipitator uses water spraying or overflow water to form a water film on the surface of the dust collecting electrode to achieve plate cleaning. Wet cleaning can avoid the re-flying of settled dust and achieve a very high dust removal efficiency. When the wet electrostatic precipitator is actually used, it is necessary to equip it with a sludge treatment device to complete the sludge treatment inside the wet electrostatic precipitator. It has the advantages of simple operation, stable structure and good use effect.

In the above utility model, the jet device includes a first jet pipe, a second jet pipe, a main air pipe, a first jet head and a second jet head. The gas is ejected through multiple first jet heads and multiple second jet heads, which can blow the sludge attached to the bottom surface of the box to achieve sludge treatment.

The rotating air storage disk, the connecting pipe and the multiple sets of jet inclined tubes can avoid the attachment of sludge by using centrifugal force. By setting up the air storage disk, the number of nozzle structures used can be reduced, and the position of gas discharge can be changed to ensure that the sludge is fully cleaned, thereby improving the practicality of the internal sludge treatment device for the wet electrostatic precipitator.

The rotating second driven gear can drive the filter to rotate through the air intake pipe. The rotating filter can use centrifugal force to shake off impurities attached to its surface. The gas entering the interior of the air intake box can be heated by the electric heater. The heated gas enters the interior of the box and can be dried. The air intake box is provided with a filtering structure, which can prevent impurities in the gas from clogging the nozzle structure, thereby ensuring the continuous use of the internal sludge treatment device for the wet electrostatic precipitator.

Therefore, the control method and circuit connection will not be described in detail.

[0039] Working principle:

[0040] When the internal sludge treatment device for the wet electrostatic precipitator is actually used, the control panel is used to operate the drive motor 6 and the air pump 7. The output end of the drive motor 6 can drive the first main gear 9 to rotate. Since the first main gear 9 and the first driven gear 10 are engaged with each other, the rotating first main gear 9 can drive the first driven gear 10 to rotate. The rotating first driven gear 10 can drive the air storage disk 3 to rotate through the shaft tube 17. The rotating air storage disk 3 can drive the connecting pipe 11 to rotate. In this process, since the socket gear 13 and the inner gear ring 16 are engaged with each other, the fixed inner gear ring 16 can drive the socket gear 13 to rotate, and the rotating socket gear 13 can drive The connecting pipe 11 is driven to rotate.

The air pump 7 can draw the gas inside the air inlet box 5 into the interior of the air storage disk 3 through the exhaust pipe, the air guide pipe 12 and the shaft tube 17. The gas inside the air storage disk 3 enters the interior of the connecting pipe 11, and finally the gas can be ejected through the multiple sets of jet inclined pipes 15. The ejected gas can blow the sludge attached to the inner wall of the box body 1. The multiple sets of one-way valves can prevent the sludge from entering the interior of the connecting pipe 11 through the multiple sets of jet inclined pipes 15. The rotating air storage disk 3, the connecting pipe 11 and the multiple sets of jet inclined pipes 15 can avoid the adhesion of sludge by the action of centrifugal force. Disk 3, while reducing the number of nozzle structures used, can change the position of gas discharge, ensure that the sludge is fully cleaned, and improve the practicality of the internal sludge treatment device for the wet electrostatic precipitator. At the same time, according to the above operation, the air pump 7 can extract the gas inside the air intake box 5 through the exhaust pipe. When the air intake box 5 is in a negative pressure state, the external gas can enter the interior of the air intake box 5 through the air intake pipe 18. The filter 19 can prevent impurities in the gas from entering the interior of the air intake box 5 through the air intake pipe 18. The control panel is used to make the servo motor 20 and the electric heater 23 work, and the output end of the servo motor 20 can drive the second main gear 2 1 rotates. Since the second main gear 21 and the second driven gear 22 are engaged with each other, the rotating second main gear 21 can drive the second driven gear 22 to rotate. The rotating second driven gear 22 can drive the filter screen 19 to rotate through the air intake pipe 18.
