Description

Technical Field

[0001] This utility model relates to the technical field of wet electrostatic precipitator equipment, specifically to a wet electrostatic precipitator for treating high-sulfur flue gas with a self-cleaning function. Background Technology

[0002] Wet electrostatic precipitators are high-efficiency dust removal devices that use a high-voltage electric field to charge dust particles in flue gas and then capture the dust through water mist or water film. They are commonly used for flue gas purification in industries such as coal-fired power plants, steel, and chemicals. For example, when purifying high-sulfur flue gas, it is passed into a wet electrostatic precipitator and subjected to high-voltage treatment, causing the dust to adhere to the dust collection plates inside the device, thereby purifying it.

[0003] After a period of purification, the dust collection plate is usually cleaned to wash away the dust adhering to its surface. To facilitate cleaning, the equipment is equipped with a washing device. A water sprayer is installed above the dust collection plate to spray water into a mist, which washes away the dust on the dust collection plate.

[0004] However, in wet electrostatic precipitators, the spray buckets inside are mostly fixed above the dust collection plate to spray water mist and water, making it difficult to clean both sides of the dust collection plate at the same time. Furthermore, the spray buckets are difficult to adjust in angle, resulting in incomplete cleaning of the dust collection plate. Utility Model Content

[0005] This utility model proposes a wet electrostatic precipitator for treating high-sulfur flue gas with a self-cleaning function, which solves the problem in the prior art that it is difficult to adjust the position of the spray bucket when spraying and cleaning the dust collection plate, resulting in incomplete cleaning.

[0006] The technical solution of this utility model is as follows:

[0007] A wet electrostatic precipitator with self-cleaning function for treating high-sulfur flue gas includes a dust collector body, a dust collection plate installed inside the dust collector body, a connecting frame, a spray washing assembly, and a placement cover. Two connecting frames are provided, and both connecting frames are mounted on the side of the dust collector body via a lifting assembly. The spray washing assembly is mounted on the connecting frames and is used to spray wash the dust collection plate. Two through slots are opened at the top of the dust collector body, and the two placement covers are detachably installed at the two through slots.

[0008] Furthermore, the lifting assembly includes a support cover, a drive screw, a motor, a moving block, a connecting plate, and a sliding assembly. The support cover is fixedly installed on the side of the dust removal equipment body. The drive screw is rotatably installed inside the support cover. The motor is installed at the top of the support cover, and the output end of the motor is coaxially connected to the drive screw. The moving block is threaded onto the drive screw. One of the connecting brackets is fixedly installed on the side of the moving block. The connecting plate is fixedly installed on the side of the moving block. The sliding assembly is located on the side of the dust removal equipment body.

[0009] Furthermore, the sliding assembly includes a second support cover, a sliding rod, a sliding block, and a second connecting plate. The second support cover is fixedly installed on the side of the dust removal equipment body, the sliding rod is fixedly installed inside the second support cover, the sliding block is slidably installed on the sliding rod, and another connecting bracket is fixedly installed on the side of the sliding block, and the second connecting plate is fixedly installed on the side of the sliding block.

[0010] Furthermore, the spraying assembly includes a U-shaped tube, a connecting tube, a spray bucket, and a water receiving pipe. The U-shaped tube is fixedly installed between the two connecting frames by a connecting ring, and the U-shaped tube is slidably installed through the two placement covers. There are two connecting tubes, and the U-shaped tube is connected to the top ends of the two connecting tubes. The connecting tube is located inside the dust removal equipment body, and several spray buckets are connected to the side of the connecting tube. The water receiving pipe is connected to the side of the U-shaped tube.

[0011] In order to enable spraying on both sides of the dust collection plate, the dust collection plate is further disposed between the two connecting pipes.

[0012] In order to allow the sprayed water to flow out, the bottom of the dust removal equipment body is provided with a through groove, and a water collection hopper is detachably installed in the through groove. A valve is connected to the bottom of the water collection hopper, and the dust collection plate is located above the water collection hopper.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, when the dust collection plate is sprayed after dust collection is completed, the lifting component can drive the spraying component to move up and down, so that the spraying bucket can be adjusted back and forth on the side of the dust collection plate, thereby driving the spraying bucket to spray the side of the dust collection plate while moving up and down, so that the spraying is more complete.

[0015] 2. In this utility model, the dust collection plate is placed vertically inside the dust removal equipment body, and the dust collection plate is located in the middle of the two sets of spray buckets, so that both sides of the dust collection plate can be sprayed with water, and after spraying, the water can fall into the water collection bucket for collection.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-5As shown, this embodiment proposes a wet electrostatic precipitator for treating high-sulfur flue gas with a self-cleaning function. It includes a dust removal device body 1, a dust collection plate 2 installed inside the dust removal device body 1, a connecting frame 3, a spray washing assembly, and a placement cover 4. There are two connecting frames 3, and both connecting frames 3 are set on the side of the dust removal device body 1 through a lifting assembly. The spray washing assembly is set on the connecting frame 3 and is used to spray wash the dust collection plate 2. Two through slots are opened at the top of the dust removal device body 1, and two placement covers 4 are detachably installed at the two through slots.

[0026] like Figure 4 As shown, an inlet pipe 19 and an outlet pipe 20 are respectively connected and installed on both sides of the dust removal equipment body 1. High sulfur dust is introduced into the dust removal equipment body 1 through the inlet pipe 19. The dust is absorbed by the fan and passes through the dust removal equipment body 1. Electrodes are installed inside the dust removal equipment body 1 to form an electric field. The dust moves towards the dust collection plate 2 through the electric field, and after impact, it is charged and deposited or attached to the dust collection plate 2. Finally, the clean gas is discharged through the outlet pipe 20.

[0027] like Figure 3 As shown, after dust removal is completed, when cleaning the dust collection plate 2, the spraying component is first moved down to the side of the dust collection plate 2 by the lifting component. The lifting component includes a support cover 5, a drive screw 6, a motor 7, a moving block 8, a connecting plate 9, and a sliding component. The support cover 5 is fixedly installed on the side of the dust removal equipment body 1. The drive screw 6 is rotatably installed inside the support cover 5. The motor 7 is installed at the top of the support cover 5, and the output end of the motor 7 is coaxially connected to the drive screw 6. The moving block 8 is threaded onto the drive screw 6. One of the connecting brackets 3 is fixedly installed on the side of the moving block 8. The connecting plate 9 is fixedly installed on the side of the moving block 8. The sliding component is located on the side of the dust removal equipment body 1. The sliding component includes a support cover 10. The sliding rod 11, sliding block 12, and connecting plate 21 are fixedly installed on the side of the dust removal equipment body 1, and the supporting cover 20 is fixedly installed inside the supporting cover 20. The sliding block 12 is slidably installed on the sliding rod 11, and another connecting frame 3 is fixedly installed on the side of the sliding block 12. The connecting plate 21 is fixedly installed on the side of the sliding block 12. Specifically, the motor 7 is started, and the motor 7 drives the drive screw 6 to rotate inside the supporting cover 15, thereby driving the moving block 8 and the connecting plate 19 to move up and down. Under the drive of the connecting frame 3 and the connecting ring, the other connecting frame 3 and the connecting plate 2 are synchronously driven to move up and down on the sliding rod 11 through the sliding block 12, so that the spraying assembly moves back and forth up and down on both sides of the dust collection plate 2.

[0028] like Figure 2 and Figure 5As shown, while moving up and down, the dust collection plate 2 can be sprayed by the spray washing assembly. The spray washing assembly includes a U-shaped pipe 13, a connecting pipe 14, a spray bucket 15, and a water receiving pipe 16. The U-shaped pipe 13 is fixedly installed between two connecting frames 3 by a connecting ring, and the U-shaped pipe 13 is slidably installed on two placement covers 4. There are two connecting pipes 14, and the U-shaped pipe 13 is connected to the top of the two connecting pipes 14. The connecting pipes 14 are located inside the dust removal equipment body 1. Several spray buckets 15 are connected to the side of the connecting pipes 14. The water receiving pipe 16 is connected to the side of the U-shaped pipe 13. Specifically, the water receiving pipe 16 is connected to a water source by a water pump. Water enters the two connecting pipes 14 through the water inlet pipe 16 and the U-shaped pipe 13, and is sprayed onto the side of the dust collection plate 2 in the form of water mist through the spray bucket 15. It should be noted that the water inlet pipe 16 is a flexible hose, and the dust collection plate 2 is located between the two connecting pipes 14, so both sides of the dust collection plate 2 can be sprayed. Because the bottom of the dust removal equipment body 1 has a through groove, a water collection bucket 17 can be detachably installed in the through groove. The bottom of the water collection bucket 17 is connected to a valve 18, and the dust collection plate 2 is located above the water collection bucket 17. The sprayed water mist can drip into the water collection bucket 17, which makes it convenient to open the valve 18 to let it flow out, and it can be disassembled and cleaned periodically.

[0029] When removing dust from flue gas, the connecting pipe 14 and the spray bucket 15 can be moved up into the interior of the placement hood 4, so that the flue gas will not be blocked by the connecting pipe 14 and the spray bucket 15 when it passes through, and can pass smoothly through the dust collection plate 2. The gap between the water collection bucket 17 and the placement hood 4 and the dust removal equipment body 1 can be sealed with a sealing strip to prevent the flue gas from escaping. The sealing strip can also be sealed when the U-shaped pipe 13 does not need to be raised and lowered through the placement hood 4.

[0030] Working principle: After the flue gas is filtered, the water inlet pipe 16 is connected to the water source through the water pump. The water then enters the two connecting pipes 14 through the water inlet pipe 16 and the U-shaped pipe 13, and is sprayed as water mist on the side of the dust collection plate 2 through the spraying bucket 15. The sprayed water mist drips into the water collection bucket 17, which facilitates the subsequent opening of the valve 18 to allow it to flow out. It can also be disassembled for cleaning periodically. At the same time as spraying, the motor 7 is started. The motor 7 drives the drive screw 6 to rotate in the support cover 5, thereby driving the moving block 8 and the connecting plate 9 to move up and down. Driven by the connecting frame 3 and the connecting ring, the other connecting frame 3 and the second connecting plate move up and down on the sliding rod 11 through the sliding block 12, so that the spraying components move back and forth up and down on both sides of the dust collection plate 2, thereby spraying and cleaning the dust collection plate 2 more completely.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
