Description
Technical Field
[0001] This utility model relates to the field of electrostatic dust removal technology, and in particular to a wet electrostatic dust precipitator. Background Technology
[0002] Wet electrostatic precipitators are a type of gas dust removal method that is widely used in industries such as metallurgy and chemicals. During the wet electrostatic precipitator process, dust tends to adhere to the dust collection plate, making it difficult to clean. This results in the dust particles on the dust collection electrodes not being able to release their charge, thus affecting the dust removal efficiency.
[0003] To address the aforementioned problems, those skilled in the art have made improvements to existing technologies. For example, a type of environmentally friendly wet electrostatic precipitator with easy cleaning, disclosed in CN218981920U, includes a dust collector body. The top and bottom of the inner cavity of the dust collector body are respectively provided with an upper fixed plate and a lower fixed seat. Multiple sets of dust collection plates are provided between the upper fixed plate and the lower fixed seat. A stepper motor is located in the middle of the lower surface of the dust collector body. The output end of the stepper motor is connected to a rotating shaft, and a linkage mechanism is provided on the rotating shaft. The linkage mechanism includes multiple sets of threaded rods, each set of which is threaded with... The device is equipped with a threaded sleeve, and cleaning plates are provided on both sides of the threaded sleeve. Water storage tanks are connected to the bottom sides of the dust collector body through drain pipes. The water storage tanks are connected to the upper fixed plate through a water supply mechanism. Multiple sets of nozzles are provided on both sides of the lower surface of the upper fixed plate, which can clean the dust collection plate. However, the flushing nozzles in the above device are fixed, which greatly reduces the flushing force when cleaning the lower half of the dust collection plate. Moreover, the above device lacks a mechanism for cleaning the cleaning plate itself. After long-term use, dust easily adheres to the surface of the cleaning plate, resulting in a decrease in its cleaning effect on the dust collection plate.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0010] According to the present invention, in the wet electrostatic precipitator, when the torsion spring is in its natural state, the water outlet end of the nozzle faces the dust collection plate; when the lifting component is at the lowest end of its movement range, the locking component cooperates with the bending deflector, and the water outlet end of the nozzle faces the brush roller.
[0011] According to the present invention, a wet electrostatic precipitator is provided on the side wall of the precipitator below the partition plate. The water pipe extends upward and passes through the precipitator and connects to the side wall of the precipitator.

[0016] In summary, the beneficial effects of this utility model are: it can both flush the dust collection plate and self-clean the brush roller, ensuring a good cleaning effect and reducing manufacturing and usage costs. Attached Figure Description

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0025] See Figures 1-6This utility model provides a wet electrostatic precipitator, comprising:
[0026] The dust collector 1 has several dust collection plates 2 fixedly installed inside. There are certain gaps between adjacent dust collection plates 2 and between the dust collection plates 2 and the side wall of the dust collector 1. When energized, the dust collection plates 2 are used to collect dust and other impurities in the gas (the working principle and internal configuration of the dust collector 1 are common knowledge to those skilled in the art and will not be described in detail in this utility model). The dust collector 1 has an air inlet 11 and an air outlet on the side walls at both ends (the air outlet and the air inlet 11 have similar structures, so they will not be described in detail in this application).
[0027] Several rotating shafts 6 are vertically rotatably installed inside the dust collector 1. Rotating shafts 6 are installed on both sides of the end of the dust collection plate 2. The top and bottom ends of the rotating shafts 6 are rotatably connected to the top and bottom surfaces of the dust collector 1, respectively. A positive rotating shaft sleeve 61 is rotatably fitted on the top of the rotating shaft 6. A positive ratchet 62 is provided on the side wall of one end of the positive rotating shaft sleeve 61. The positive ratchet 62, the positive rotating shaft sleeve 61 and the rotating shaft 6 are concentric. A positive pawl that can rotate in one direction is rotatably provided on the rotating shaft 6. When the rotating shaft 6 rotates in the forward direction, the positive ratchet 62 cooperates with the positive pawl, so that the rotating shaft 6 drives the positive rotating shaft sleeve 61 to rotate in the forward direction.
[0028] The lifting component 7 corresponds to the rotating bushing 61. Each rotating bushing 61 has a reciprocating groove 63 on its surface that mates with the lifting component 7. Each lifting component 7 has a through hole through which the rotating bushing 61 passes. The inner wall of the through hole has a guide post that mates with the reciprocating groove 63 (the mating method and principle are the same as those for a reciprocating lead screw). When the rotating bushing 61 rotates in one direction, it drives the lifting component 7 to reciprocate up and down along the rotating bushing 61. A connecting plate 71 is fixedly installed between the two lifting components 7 on the same side of the dust collection plate 2. Both ends of the connecting plate 71 are fixedly connected to the two lifting components 7. A cleaning shaft 8 is rotatably installed on the bottom side of the connecting plate 71 closest to the dust collection plate 2. Both ends of the cleaning shaft 8 are rotatably connected to the connecting plate 71. A brush roller 82 is fixedly connected to the cleaning shaft 8. When the lifting component 7 drives the brush roller 82 to reciprocate up and down, it can clean the dust collection plate 2. The top of the connecting plate 71 near the dust collection plate 2 is provided with a flushing pipe 91. Several nozzles 92 are fixedly installed on the flushing pipe 91. Auxiliary shafts 9 are fixedly connected to both ends of the flushing pipe 91. The auxiliary shafts 9 are rotatably connected to the connecting plate 71. Torsion springs are provided at the connection between the auxiliary shafts 9 and the connecting plate 71 (torsion springs are mature existing technology and are mostly used between shafts to provide power for automatic reset of the shafts, which will not be described in detail in this utility model). When the torsion spring is in its natural state, the water outlet of the nozzles 92 is facing the dust collection plate 2.
[0029] See Figures 1-6Preferably, gears 81 are fixedly connected to both ends of the cleaning shaft 8, and fixed racks 12 corresponding to the gears 81 are fixedly connected to the side wall of the dust collector 1. When the lifting component 7 drives the cleaning shaft 8 to reciprocate, the cleaning shaft 8 can drive the brush roller 82 to reciprocate while rotating under the meshing action of the gears 81 and the fixed racks 12, thereby improving the cleaning effect.
[0030] The reversible bushing 10 corresponds to and is fitted with the rotating shaft 6. The reversible bushing 10 is rotatably mounted at the bottom of the rotating shaft 6. Each reversible bushing 10 has a reverse ratchet 104 (similar in structure to the forward ratchet 62, but in the opposite direction) on one side wall. The reverse ratchet 104, reversible bushing 10, and rotating shaft 6 are concentric. The rotating shaft 6 has a unidirectional rotatable reverse pawl. When the reverse ratchet 104 engages with the reverse pawl, the rotating shaft 6 can drive the reversible bushing 10 to reverse. Each reversible bushing 10 has a reciprocating component 101 (its engagement method is the same as that of the forward rotating bushing 61 and the lifting component 7). When the reversible bushing 10 reverses, it can drive the reciprocating component 101 to reciprocate up and down along the reversible bushing 10. Each reciprocating component 101 has a fixed connecting rod 103 fixedly connected to the side wall near the cleaning shaft 8. Each fixed connecting rod 103 has a fixedly connected movable rack 102 that meshes with the gear 81.
[0031] See Figures 1-6 Preferably, each auxiliary shaft 9 is fixedly connected with a bending plate 93, and each vertical side wall of the dust collector 1 is fixedly connected with a clamp 13 that cooperates with the bending plate 93. When the lifting member 7 descends to the lowest point of its movement range, the bending plate 93 cooperates with the clamp 13, causing the auxiliary shaft 9 to rotate so that the nozzle 92 faces the brush roller 82.
[0032] See Figures 1-6 Preferably, the bottom of the dust collector 1 is fixedly provided with a partition plate 3, and the top surface of the partition plate 3 is provided with a number of supporting protrusions 4 for connecting the dust collection plates 2. The partition plates 3 between adjacent dust collection plates 2 are provided with a filtration zone 31, and a filtration mechanism (such as an activated carbon filter layer) is provided above the partition plate 3 at the filtration zone 31, which can realize water circulation.
[0033] See Figures 1-6 Preferably, a water pipe 5 is fixedly connected to the side wall of the dust collector 1 below the partition plate 3. The water pipe 5 extends upward and passes into the dust collector 1, and is fixedly connected to the side wall of the dust collector 1. An elastic telescopic pipe 51 is fixedly connected between the water pipe 5 and the flushing pipe 91 (the elastic telescopic pipe 51 can adapt to deformation and elongate when the lifting member 7 descends, and can also recover its deformation and shorten when the lifting member 7 rises, ensuring a stable water supply). It is used to supply water to the flushing pipe 91. A water pump is connected to the water pipe 5. The water pump can transport the water below the partition plate 3 into the water pipe 5 and pressurize the water to assist in completing the flushing.
[0034] See Figures 1-6 Preferably, both the lifting component 7 and the reciprocating component 101 are slidably connected to the side wall of the dust collector 1, which can prevent them from rotating during movement.
[0035] See Figures 1-6 Preferably, a belt 64 is connected between several rotating shafts 6, and one of the rotating shafts 6 is connected to a drive unit. The drive unit is installed on the side wall of the dust collector 1. The user can set a suitable pulley on the rotating shaft 6 to adjust the belt wrap angle, or add a sprocket on the rotating shaft 6 and replace the belt 64 with a chain that can cooperate with the sprocket to ensure good transmission efficiency. These are all existing technologies, so they will not be described in detail.
[0036] See Figures 1-6 Preferably, the driving component is a rotary motor, which can provide sufficient power.
[0037] In the implementation of this utility model: when it is necessary to clean the surface of the dust collection plate 2, the driving component drives several rotating shafts 6 to rotate forward. At this time, the forward ratchet 62 engages with the forward pawl, while the reverse ratchet 104 does not engage with the reverse pawl. The forward rotating shaft sleeve 61 rotates, while the reverse rotating shaft sleeve 10 does not rotate. The lifting component 7 drives the cleaning shaft 8 and the rinsing pipe 91 to move up and down reciprocally. During this process, the gear 81 meshes with the fixed rack 12, causing the brush roller 82 to rotate reciprocally. The water pump starts synchronously, and the nozzle 92 cleans the surface of the dust collection plate 2. After the dust collection plate 2 is cleaned, the lifting component 7 is first moved to its range of motion. At the lowest point of the enclosure, the locking piece 13 engages with the bending plate 93, and the water outlet of the nozzle 92 faces the brush roller 82. Then, the driving component drives several rotating shafts 6 to reverse. At this time, the positive ratchet 62 does not engage with the positive pawl, and the negative ratchet 104 engages with the negative pawl. The positive rotating shaft sleeve 61 does not rotate, and the negative rotating shaft sleeve 10 rotates. The reciprocating component 101 moves up and down repeatedly. Under the meshing action of the moving rack 102 and the gear 81, the brush roller 82 rotates back and forth. The water pump starts to clean the brush roller 82. The used water flows to the bottom of the partition plate 3 after passing through the filtration mechanism and can be reused.
[0038] This utility model provides a wet electrostatic precipitator, which has the following beneficial effects:
[0039] By setting up liftable brush rollers and flushing pipes, the dust collection plate can be repeatedly flushed, ensuring good cleaning effect and improving cleaning efficiency.
[0040] By incorporating a rotatable flushing pipe and a reverse bushing, the brush roller can be cleaned when idle, preventing dust from adhering to the brush roller and reducing its cleaning effect, thus further improving the cleaning performance.
[0041] In this invention, cleaning of the dust collection plate and cleaning of the brush roller can be achieved with only one drive component, reducing manufacturing and usage costs.
[0042] In summary, the beneficial effects of this utility model are: it can both flush the dust collection plate and self-clean the brush roller, ensuring a good cleaning effect and reducing manufacturing and usage costs.
[0043] Of course, there may be many other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
