Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a wet electrostatic dust removal device. Background Technology
[0002] An electrostatic precipitator is a device that uses the principle of electrostatics to remove dust from gas. Its working principle involves ionizing the gas using a high-voltage electric field, generating positive and negative ions. Dust particles attract these ions and become charged as they pass through the electric field. Under the influence of the electric field, they move towards the electrodes and deposit on the collecting electrodes, thus achieving the separation of dust from the gas.
[0003] Wet electrostatic precipitators are air purification devices that combine electrostatic principles with wet dust removal technology. They are mainly used to treat fine particulate matter, heavy metals, and organic pollutants in dusty gases. In existing technologies, traditional wet electrostatic precipitators typically spray the dust removal liquid onto the bottom wall of the electrode plate. However, the spraying area of the dust removal liquid is limited, and it cannot be evenly sprayed onto the bottom wall of the electrode plate. Consequently, it cannot fully contact and wet the dust particles, reducing the dust removal effect and making it impractical. Therefore, it is necessary to redesign a wet electrostatic precipitator to address the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wet electrostatic dust removal device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A wet electrostatic precipitator includes a dust collection box. An inlet pipe and an exhaust pipe, communicating with the interior, are fixedly installed on the outer walls of both sides of the dust collection box. An electrode plate is fixedly installed inside the dust collection box. A spray pipe is rotatably installed through the dust collection box. Multiple nozzles communicating with the interior are fixedly installed on the outer wall of the spray pipe. A motor is fixedly installed on the outer wall of the dust collection box via a support mechanism. Pullers are fixedly installed on both the motor output shaft and the outer wall of the spray pipe. Two of the pulleys are connected by a belt for transmission. A liquid storage tank is fixedly installed on the outer wall of the dust collection box. The upper surface of the liquid storage tank has a filling port communicating with the interior. A liquid pump is fixedly installed on the upper surface of the liquid storage tank. The inlet pipe of the liquid pump extends into the interior of the liquid storage tank. The outlet pipe of the liquid pump is rotatably connected to the outer wall of the spray pipe through a connecting mechanism. The bottom wall of the dust removal box is inclined. A drain pipe communicating with the interior is fixedly installed on the outer wall of the dust removal box. A collection box is fixedly connected to the outer wall of the dust removal box through a fixing mechanism. A filter plate is slidably installed inside the collection box through a limiting plate. A collection bucket is slidably installed on the outer wall of the collection box through a pull-out opening.
[0007] Preferably, the support mechanism includes a support plate fixedly installed on the outer wall of the dust collector, and the motor is fixedly installed on the outer wall of the support plate.
[0008] Preferably, the connecting mechanism includes a connecting sleeve fixedly installed on the outer wall of the liquid pump outlet pipe, and the inner wall of the connecting sleeve is rotatably connected to the outer wall of the spray pipe.
[0009] Preferably, the fixing mechanism includes two fixing rods fixedly installed on the outer wall of the dust collection box, and the ends of the two fixing rods are fixedly connected to the outer wall of the collection box.
[0010] Preferably, the outer wall of the dust collector is provided with an observation port communicating with the interior, and an observation window is fixedly installed inside the observation port.
[0011] Preferably, a rotating rod is rotatably installed through the outer wall of the observation window, and a cleaning plate is fixedly installed at the end of the rotating rod.
[0012] The beneficial effects of this utility model are:
[0013] 1. By setting up components such as spray pipes, motors and pulleys, the motor can drive the spray pipes to rotate on the inner wall of the connecting sleeve through two pulleys connected by a belt. At this time, the spray pipes can spray the dust removal liquid during the rotation, which can make the dust removal liquid spray more evenly, fully contact and wet the dust particles, and form a mud-like substance.
[0014] 2. By setting up components such as a collection box, filter plate and collection bucket, the filter plate inside the collection box can perform solid-liquid separation of mud-like substances. The separated dust removal liquid can flow into the collection bucket, thereby realizing the recycling and reuse of the dust removal liquid, thereby reducing water waste and avoiding secondary pollution.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5 A wet electrostatic precipitator includes a dust collection box 1. An air inlet pipe 2 and an exhaust pipe 3, communicating with the interior, are fixedly installed on the outer walls of both sides of the dust collection box 1. An electrode plate 4 is fixedly installed inside the dust collection box 1. A spray pipe 5 is rotatably installed through the dust collection box 1. Multiple nozzles 6, communicating with the interior, are fixedly installed on the outer wall of the spray pipe 5. A motor 8 is fixedly installed on the outer wall of the dust collection box 1 via a support mechanism. The support mechanism includes a support plate 7 fixedly installed on the outer wall of the dust collection box 1. The motor 8 is fixedly installed on the outer wall of the support plate 7. Pulleys 9 are fixedly installed on both the output shaft of the motor 8 and the outer wall of the spray pipe 5. The two pulleys 9 are connected by a belt for transmission. A liquid storage tank 10 is fixedly installed on the outer wall of the dust collection box 1.
[0023] The upper end face of the liquid storage tank 10 is provided with a filling port that communicates with the interior. A liquid pump 11 is fixedly installed on the upper end face of the liquid storage tank 10. The inlet pipe of the liquid pump 11 extends into the interior of the liquid storage tank 10. The outlet pipe of the liquid pump 11 is rotatably connected to the outer wall of the spray pipe 5 through a connecting mechanism. The connecting mechanism includes a connecting sleeve 12 fixedly installed on the outer wall of the outlet pipe of the liquid pump 11. The inner wall of the connecting sleeve 12 is rotatably connected to the outer wall of the spray pipe 5. The inner bottom wall of the dust collector 1 is inclined. The inner bottom wall of the cleaning setting can facilitate the smooth discharge of mud-like substances through the drain pipe 13. A drain pipe 13 that communicates with the interior is fixedly installed on the outer wall of the dust collector 1. A collection box 15 is fixedly connected to the outer wall of the dust collector 1 through a fixing mechanism. The fixing mechanism includes two fixing rods 14 fixedly installed on the outer wall of the dust collector 1. The ends of the two fixing rods 14 are fixedly connected to the outer wall of the collection box 15.
[0024] Inside the collection box 15, a filter plate 17 is slidably installed via a limiting plate 16. On the outer wall of the collection box 15, a collection bucket 18 is slidably installed via a pull-out opening. The outer wall of the dust collector 1 has an observation port that communicates with the interior. An observation window 19 is fixedly installed inside the observation port. A rotating rod 20 is rotatably installed through the outer wall of the observation window 19. A cleaning plate is fixedly installed at the end of the rotating rod 20.
[0025] When using this utility model, dust removal liquid can be added into the storage tank 10 through the filling port. During dust removal, dust-laden gas can enter the dust removal box 1 through the air inlet pipe 2. At this time, the electrode plate 4 can form an electrostatic field with the cooperation of the high voltage power supply, thereby adsorbing the dust in the air onto its bottom wall. The dust-removed air can be discharged from the dust removal box 1 through the exhaust pipe 3. When treating the dust adsorbed on the bottom wall of the electrode plate 4, the liquid pump 11 can pump the dust removal liquid into the storage tank 10 through its inlet pipe, and pump the dust removal liquid out into the spray pipe 5 through the cooperation of its outlet pipe and the connecting sleeve 12. At this time, the dust removal liquid can be sprayed out through multiple nozzles 6 inside the spray pipe 5 to wet the bottom wall of the electrode plate 4.
[0026] Meanwhile, the motor 8 drives the spray pipe 5 to rotate via two pulleys 9 connected by a belt. During this rotation, the spray pipe 5 sprays the dust removal liquid, which allows for more even spraying, ensuring full contact and wetting of the dust particles to form a slurry-like substance. This slurry-like substance falls onto the inclined inner bottom wall of the dust collection box 1 under gravity and flows into the collection box 15 through the drain pipe 13. The filter plate 17 inside the collection box 15 can then perform solid-liquid separation on the slurry-like substance. The separated dust removal liquid can flow into the collection bucket 18, thus enabling the recovery and recycling of the dust removal liquid. The filter plate 17 can be slid out from the upper surface of the collection box 15 for cleaning. During the dust removal process, the dust removal work inside the dust collection box 1 can be observed through the observation window 19. If dust adheres to the inner wall of the observation window 19 and affects observation, the rotating rod 20 can be turned to rotate the cleaning plate, thereby cleaning the inner wall of the observation window 19 and ensuring the observation effect.
