[0002] During combustion inside an industrial boiler, sulfides and nitrates are produced in the high-temperature flue gas, which will pollute the external environment. Specific equipment is needed to purify the flue gas.

[0003] The flue gas dust removal device of the prior art, such as the utility model patent document with authorization announcement number "CN220258339U" and patent name "A boiler flue gas dust removal device", discloses a boiler flue gas dust removal device, including an air inlet pipe, one side of the air inlet pipe is fixedly connected to a treatment box, the interior of the treatment box is fixedly connected to a partition plate, the partition plate divides the treatment box into a water storage chamber and a sewage chamber, the top of the water storage chamber is equipped with an atomizing nozzle, and the top of the sewage chamber is equipped with a dust removal anode plate.

[0004] In the above patent, dust is collected by dust removal anode plates. However, after the device is used for a long time, the dust on the anode plates will cover the surface of the anode plates. At this time, the adsorption force of the anode plates on the dust is greatly reduced, and the operator is required to clean the surface of the anode plates. Since the anode plates are arranged in multiple pieces, the workload of the operator in cleaning the anode plates is increased. Summary of the invention

[0005] The purpose of the present invention is to propose a boiler flue gas dust removal device to address the deficiencies in the prior art, which is used to solve the problem that the flue gas dust removal device of the prior art mentioned in the background technology collects dust through dust removal anode plates, but when the device is used for a long time, the dust on the anode plates will cover the surface of the anode plates. At this time, the adsorption force of the anode plates on the dust is greatly reduced, and the operator is required to clean the surface of the anode plates. Since the anode plates are arranged in multiple pieces, the technical problem of the operator's work intensity in cleaning the anode plates is aggravated.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A boiler flue gas dust removal device comprises a desulfurization chamber and a dust removal chamber, wherein one side of the desulfurization chamber is connected to an air inlet pipe, the top of the dust removal chamber is connected to an exhaust pipe, the desulfurization chamber and the bottom of the dust removal chamber are connected to a smoke exhaust pipe, a hollow first rotating rod is rotatably arranged in the desulfurization chamber, a water pump for pumping reagents into the first rotating rod is arranged below the desulfurization chamber, two spray pipes are connected to the first rotating rod and the two spray pipes are distributed in a cross shape from top to bottom with the first rotating rod as the center, a plurality of the spray pipes are each provided with a plurality of spray heads, and a plurality of the desulfurization chamber is provided with A wiping assembly for wiping the spray head, the dust removal chamber is conductively connected with the desulfurization chamber, a baffle is fixedly arranged in the desulfurization chamber, a plurality of anode plates are arranged in the dust removal chamber and the tops of the anode plates are rotatably arranged in the dust removal chamber, a plurality of cathode corona wires are arranged in the dust removal chamber and each cathode corona wire is located between two adjacent anode plates, an oscillating assembly for oscillating impurities on the anode plates is arranged in the dust removal chamber, a collecting box for collecting impurities on the anode plates is arranged at the bottom of the dust removal chamber, and a driving assembly for driving the first rotating rod and the oscillating assembly is arranged below the desulfurization chamber.

[0008] Working principle:

[0009] First, the operator guides the flue gas into the desulfurization chamber through the air intake pipe, and then the operator starts the driving component. The driving component drives the first rotating rod to rotate, and the first rotating rod drives the spray pipe and the spray head to rotate. The water pump guides the desulfurization liquid to the spray head, so that the rotating spray head can desulfurize the flue gas in the desulfurization chamber. Since there may be large particles of impurities in the flue gas that are easy to adhere to the spray head, the operator can wipe the spray head through the wiping component. When the flue gas desulfurization treatment is completed, the flue gas flows into the dust removal chamber through the baffle. At this time, the operator generates a high-voltage electrostatic field through the cathode corona wire, which can adsorb impurities such as dust in the flue gas on the anode plate. The dust-removed flue gas is guided to the external space. When it is necessary to clean the impurities attached to the anode plate, the oscillation component can oscillate the impurities adsorbed on the anode plate, so that the impurities adsorbed on the anode plate fall into the collection box.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, a water pump and a first rotating rod are provided. The desulfurization liquid can be directed to the inside of the first rotating rod through the first water pump. The spray pipe and the spray head on the first rotating rod can spray the desulfurization liquid toward the flue gas, so that the flue gas and the desulfurization liquid are combined, thereby completing the desulfurization operation of the flue gas.

[0012] Second, an anode plate and a cathode corona wire are provided, and a high-voltage electrostatic field can be generated by the cathode corona wire. The dust in the flue gas can be adsorbed on the anode plate under the action of the high-voltage electrostatic field.

[0013] Thirdly, an oscillating component is provided, which can oscillate the anode plate. After the anode plate is vibrated, the dust adsorbed on the anode plate can fall into the collection box.

[0014] Fourthly, a driving assembly is provided, through which the first rotating rod and the oscillating assembly can be driven, so as to facilitate the rotation of the spray head on the first rotating rod, and the oscillating assembly can oscillate the impurities on the anode plate.

[0032] Working principle:

[0033] First, the operator guides the flue gas that needs to be dusted into the desulfurization chamber 1 through the air inlet pipe 3, and then the operator starts the water pump 6. The water pump 6 guides the desulfurization liquid to the inside of the first rotating rod 5 and sprays the internal flue gas through the spray head 8 on the spray pipe 7. Then the operator starts the motor 25, and the motor 25 drives the fourth bevel gear 27 and the third bevel gear to rotate, so that the fifth bevel gear 28 drives the first rotating rod 5 to rotate, and then the spray head 8 can rotate in the desulfurization chamber 1 to expand the spraying range of the spray head 8.

The wastewater at the bottom of the desulfurization chamber 1 can be guided to the first filter 36 in the filter tank 35 through the drain pipe 34. The first filter 36 can filter large particles of impurities in the wastewater.

[0035] When the flue gas enters the dust removal chamber 2, the flue gas rises through the second uniform distribution plate 33. At this time, the operator generates a high-voltage electrostatic field through the cathode corona wire 11. The dust in the flue gas will gradually move toward the anode plate 10 and be adsorbed on the outer wall of the anode plate 10. The transmission rod 26 is driven by the motor 25. The transmission rod 26 drives the third sprocket 29 and the third chain 30, thereby driving the third rotating rod 21 to rotate. The rotation of the third rotating rod 21 drives the second sprocket 23 and the second chain 24, and then multiple third rotating rods 21 rotate synchronously and drive multiple cams 22 on the third rotating rods 21 to hit the side wall of the anode plate 10. The dust attached to the anode plate 10 can be vibrated and fall into the collection box 12. The first spring 43 and the abutment block 42 can avoid collisions between multiple anode plates 10.
