Description

Technical Field

[0001] This utility model relates to the field of defogging devices, and in particular to a wet electrostatic dust removal and defogging device. Background Technology

[0002] Electrostatic precipitators can be divided into two types: dry and wet. Traditional electrostatic precipitators are specifically designed for dust removal and are widely used in dust control in industries such as cement and building materials, metallurgy and chemicals, power, mining, pharmaceuticals, and papermaking.

[0003] Wet electrostatic precipitators for dust removal, smoke removal, and mist removal are suitable for dust purification, smoke removal, and mist removal in various industrial fields, including hardware, cement, building materials, ceramics, electronics, chemicals, casting, metallurgy, power, machining, and non-ferrous metals.

[0004] Wet scrubbers, commonly known as "demisters," are devices that bring dust-laden gas into close contact with a liquid (usually water). They utilize the inertial collision of water droplets and particles, the thorough mixing of water and dust, and other mechanisms to capture particles, enlarge them, or retain them within a fixed container, achieving separation of water and dust. Among related technologies, there are wet electrostatic precipitators and demisters. These first draw in dust-laden air via a pump. As the air passes through the main body of the device, the dust particles are trapped by the water mist and electrostatic adsorption plates, thus achieving dust removal. However, in this type of device, the electrostatic plates use a high-voltage electric field to charge the dust particles in the flue gas. Under the influence of the electric field, the charged dust particles separate from the airflow, moving towards the cathode and anode and adhering to them. This device lacks a cleaning structure for the electrostatic plates, resulting in a thick layer of dust accumulating on the surface of the plates after a period of use. This significantly reduces the adsorption effect and affects the overall dust removal efficiency.

[0005] Therefore, it is necessary to provide a wet electrostatic dust and mist removal device to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a wet electrostatic dust removal and defogging device, which solves the problem in related technologies that some existing wet electrostatic dust removal and defogging devices are inconvenient to clean the dust adsorbed on the surface of the electrostatic plate after long-term use, resulting in a significant reduction in the adsorption capacity of the electrostatic plate.

[0007] To solve the above-mentioned technical problems, this utility model provides a wet electrostatic dust removal and demisting device, comprising: a device body, a dust removal component disposed on the inner side of the device body, and a cleaning component disposed on the inner side of the device body;

[0008] The dust removal assembly includes an electrostatic generating plate disposed on the inner wall of the main body of the device, and a dust collection box that can slide left and right on the bottom of the inner side of the main body of the device, and a filter cloth disposed at the bottom of the dust collection box.

[0009] The cleaning assembly includes sliding frames disposed on the left and right sides of the inner wall of the main body of the device. Sliding frames are disposed on the inner sides of the two sliding frames, and cleaning plates are disposed on the front of the two sliding frames. A sponge block is disposed on the side of the cleaning plate near the electrostatic generating plate, and the back of the sponge block is in contact with the front of the electrostatic generating plate.

[0010] Preferably, the inner sides of both sliding frames are provided with meshing teeth, and the inner side of the main body of the device and the inner sides of the two sliding frames are provided with rotating rods. The peripheral surfaces of the two rotating rods are fixedly provided with shaped gears. When the two rotating rods rotate, they will cause the two shaped gears to intermittently mesh with the two sets of meshing teeth respectively.

[0011] Preferably, the rear ends of both rotating rods penetrate the inner wall of the main body of the device and extend to its back side, and the rear ends of the two rotating rods are nested together by a chain and sprocket structure.

[0012] Preferably, a drive motor is provided on the left side of the top of the main body of the device, and the output end of the drive motor is sleeved with the rear end of the left rotating rod by a belt.

[0013] Preferably, the bottom of the main body of the device is provided with two water storage tanks, the bottom of the two water storage tanks are connected to a water collection tank, the top of the water collection tank is provided with a water pump, and the top of the inner wall of the main body of the device is provided with a spray pipe horizontally, and the outlet pipe of the water pump is connected to the left end of the spray pipe.

[0015] Compared with related technologies, the wet electrostatic dust removal and demisting device provided by this utility model has the following beneficial effects:

[0016] This invention provides a wet electrostatic dust and mist removal device. The drive motor output rotates, causing two rotating rods to rotate synchronously. This causes the shaped gears to intermittently mesh with the meshing teeth, repeatedly moving the sliding frame up and down inside the sliding frame. The two sliding frames then move the cleaning plate up and down. As the cleaning plate moves up and down, the sponge block on its back wipes away dust from the surface of the electrostatic plate. The dust layer falls into the dust collection box under gravity and is then condensed into clumps by the moist water mist. The structure is simple and compact, preventing excessive dust accumulation on the surface of the electrostatic plate and ensuring its adsorption effect. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 A wet electrostatic dust removal and demisting device includes: a device body 1, a dust removal component 2 disposed on the inner side of the device body 1, and a cleaning component 3 disposed on the inner side of the device body 1.

[0024] The dust removal component 2 includes an electrostatic generating plate 21 disposed on the inner wall of the device body 1, a dust collection box 22 that can slide left and right on the bottom of the inner side of the device body 1, and a filter cloth 23 disposed at the bottom of the dust collection box 22.

[0025] By setting up an electrostatic generating plate 21 and a spray pipe 27, the drawn-in air can be effectively filtered and purified. With the filter cloth 23, when water and dust are collected, the water flows through the filter cloth 23 and back into the bottom water collection tank 25, improving the water utilization rate. At the same time, after a period of time, the dust collection box 22 can be pulled to the right to collect and process the moist dust inside.

[0026] The cleaning component 3 includes sliding frames 31 on the left and right sides of the inner wall of the main body 1. Sliding frames 32 are provided on the inner sides of the two sliding frames 31, which can slide up and down. A cleaning plate 33 is provided on the front of the two sliding frames 32. A sponge block is provided on the side of the cleaning plate 33 near the electrostatic generating plate 21. The back of the sponge block is in contact with the front of the electrostatic generating plate 21.

[0027] The rotation of the rotating rod 35 drives the rotation of the shaped gear 36, which in turn intermittently meshes with the meshing teeth 34, thereby repeatedly driving the sliding frame 32 to move up and down inside the sliding frame 31. As a result, the two sliding frames 32 on the left and right can drive the cleaning plate 33 to move up and down. When the cleaning plate 33 moves up and down, the sponge block on its back will wipe away the dust on the surface of the electrostatic plate. The dust layer falls into the dust collection box 22 under the action of gravity, and is then condensed into a block by the moist water mist. The sponge block can also be replaced by soft brush bristles.

[0028] The inner sides of the two sliding frames 32 are provided with meshing teeth 34. The inner side of the main body 1 and the inner side of the two sliding frames 32 are provided with rotating rods 35. The peripheral surfaces of the two rotating rods 35 are fixedly provided with shaped gears 36. When the two rotating rods 35 rotate, they will cause the two shaped gears 36 to intermittently mesh with the two sets of meshing teeth 34 respectively.

[0029] The rear ends of both rotating rods 35 penetrate the inner wall of the main body 1 and extend to its back side. The rear ends of the two rotating rods 35 are interlocked by a chain and sprocket structure.

[0030] By interlocking chains and sprockets, the two rotating rods on the left and right sides can be ensured to rotate synchronously.

[0031] A drive motor 37 is provided on the top left side of the main body 1 of the device. The output end of the drive motor 37 is sleeved on the rear end of the left rotating rod 35 via a belt.

[0032] Two water storage tanks 24 are provided at the bottom of the main body 1. A water collection tank 25 is connected to the bottom of the two water storage tanks 24. A water pump 26 is provided at the top of the water collection tank 25. A spray pipe 27 is horizontally arranged at the top of the inner wall of the main body 1. The outlet pipe of the water pump 26 is connected to the left end of the spray pipe 27.

[0033] The water pump 26 is located on top of the water collection tank 25, reducing the space occupied by the device. At the same time, its pipes are fixed to the support frame 28 and the outside of the device body 1 by fasteners, improving stability.

[0034] A support frame 28 is provided on the outside of the main body 1 of the device. A fan 29 is provided on the left side of the top of the support frame 28. An air inlet 4 is provided on the rear side of the fan 29 and on the top of the support frame 28. An air outlet 5 is provided on the right side of the main body 1 of the device. A handle is provided on the right side of the dust collection box 22.

[0035] The working principle of the wet electrostatic dust and mist removal device provided by this utility model is as follows:

[0036] Step 1: When in use, the operation of the fan 29 allows the outside air containing dust to enter the main body 1 of the device through the air inlet 4. At the same time, the water pump 26 and the electrostatic generator plate 21 are turned on, which can effectively filter and purify the air containing dust particles, and finally discharge it from the right outlet.

[0037] Step 2: After a period of use, the drive motor 37 can be turned on. The output of the drive motor 37 rotates and drives the two rotating rods 35 to rotate synchronously. The rotation of the two rotating rods 35 drives the rotation of the shaped gear 36, which can intermittently mesh with the meshing teeth 34, thereby repeatedly driving the sliding frame 32 to move up and down inside the sliding frame 31. Thus, the two sliding frames 32 can drive the cleaning plate 33 to move up and down. When the cleaning plate 33 moves up and down, the sponge block on its back will wipe away the dust on the surface of the electrostatic plate. The dust layer falls into the dust collection box 22 under the action of gravity, and then is condensed into a block by the moist water mist.

[0038] Step 3: Finally, the dust collection box 22 can be pulled out by the handle to remove the dust clumps inside.

[0039] Compared with related technologies, the wet electrostatic dust removal and demisting device provided by this utility model has the following beneficial effects:

[0040] The output of the drive motor 37 rotates, causing the two rotating rods 35 to rotate synchronously. This causes the shaped gear 36 to intermittently mesh with the meshing teeth 34, thereby repeatedly driving the sliding frame 32 to move up and down inside the sliding frame 31. In turn, the two sliding frames 32 drive the cleaning plate 33 to move up and down. When the cleaning plate 33 moves up and down, the sponge block on its back wipes away the dust on the surface of the electrostatic plate. The dust layer falls into the dust collection box 22 under the action of gravity, and is then condensed into a block by the moist water mist. The structure is simple and compact, which can avoid the accumulation of a lot of dust on the surface of the electrostatic plate, thus ensuring its adsorption effect.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
