Consequently, particulate matter contributes to frequent extreme weather events and meteorological disasters. Currently, high-voltage electrostatic fume and dust purifiers are a common type of equipment for purifying particulate matter.

[0003] The core component of the high-voltage electrostatic smoke and dust purifier provides a high-voltage power supply for the high-voltage dust collecting electric field. The working principle of high-voltage electrostatic dust removal is to use a high-voltage electric field to ionize the flue gas, charge the dust in the airflow, and separate it from the airflow under the action of the electric field, ultimately achieving the purpose of removing particulate pollutants in the airflow.

The electric control box 200 includes an electric control box body 202, an insulator 204, an electric control box cover 201, and a power supply 203. Screw holes are provided on the rear side wall of the electric control box body 202.

When maintenance and inspection are required, the door lock is opened, the screws are unscrewed, and the electric control box 200 is removed so that the electrostatic dust removal field 400 and the filter 500 can be taken out from the front of the housing 100.

[0051] A plurality of electrostatic precipitator fields 400 are disposed in the housing 100 and are arranged at intervals along the width direction from the air inlet 106 to the air outlet 107 .

[0053] Specifically, see Figure 9 As shown, the specific relationship between the dust collecting electrode and the discharge electrode can be in the following ways: The first distribution method is, see Figure 9As shown in Figure (a), the dust collector in this configuration consists of multiple open U-shaped structural members 2 arranged in a straight line, with adjacent U-shaped members 2 connected end-to-end and fixed to the electric field frame body 1. Each open portion accommodates a discharge electrode. Specifically, there are five U-shaped structural members 2. The first baffle 22 and the second baffle 23 of each U-shaped member 2 form a 115° angle relative to the blocking plate 21.

[0054] See also Figure 9 As shown in (b), the dust collecting pole in this method has a plurality of "U"-shaped structural members 2 with openings, and the plurality of "U"-shaped structural members 2 are linear, and two adjacent "U"-shaped structural members 2 are fixedly installed on the electric field frame body 1 at intervals, and each opening is used to accommodate a discharge electrode. Specifically, there are five "U"-shaped structural members 2. And the first baffle 22 and the second baffle 23 of each "U"-shaped structural member 2 are at an angle of 115° relative to the blocking plate 21. The two adjacent "U"-shaped structural members 2 are connected by a connecting baffle 25. It should be noted that the connecting baffle 25 is located on the side close to the opening, and the purpose is to be relative to Figure 9 As for the arrangement in (a), the gap between the baffles of adjacent "U"-shaped structural members 2 can be increased, thereby better ensuring the effective flow of air and improving the ventilation effect. Furthermore, the connecting baffle 25 can be any airtight connecting plate body of straight, V-shaped or wavy shape.

[0055] See also Figure 9 As shown in (c), the dust collecting pole in this method is a "U"-shaped structural member 2 with an open mouth, and the "U"-shaped structural member 2 is fixedly installed on the electric field frame body 1, and a plurality of discharge electrodes are arranged at intervals inside the "U"-shaped structural member 2.

[0056] See also Figure 9 As shown in (d), the dust collecting pole in this method is a "U"-shaped structural member 2 with an open mouth, and the "U"-shaped structural member 2 is fixedly installed on the electric field frame body 1, and a plurality of discharge electrodes are arranged at intervals in the "U"-shaped structural member 2, and spacers can also be arranged between adjacent discharge electrodes, which can improve the discharge effect of the discharge electrodes.

[0057] See also Figure 9 As shown in Figure (e), the dust collector in this configuration comprises multiple open U-shaped structural members 2, which are fixedly mounted to the electric field frame body 1 at intervals. Each open portion accommodates multiple discharge electrodes, which are arranged side by side in a horizontal (front-to-back) direction. Specifically, there are three U-shaped structural members 2, each of which contains two discharge electrodes spaced apart and arranged in a front-to-back direction.

[0058] See also Figure 9As shown in Figure (f), the dust collector in this method comprises multiple open U-shaped structural members 2, with adjacent U-shaped structural members 2 connected by connecting baffles 25. The multiple U-shaped structural members 2 are fixedly mounted on the electric field frame body 1 at intervals, and each open portion is used to accommodate multiple discharge electrodes, which are arranged in parallel in the longitudinal direction (left and right). Specifically, there are five U-shaped structural members 2, each of which is spaced apart and has two discharge electrodes arranged in the left and right direction.

[0059] It should also be noted that the linear high-voltage electrode 4 is equidistant from the first baffle 22 and the second baffle 23 in the front-to-back direction. The vertical distance between the linear high-voltage electrode 4 and the blocking plate 21 in the left-to-right direction is greater than or equal to the distance between the linear high-voltage electrode 4 and the first baffle 22 and the second baffle 23 to ensure the discharge effect of the discharge electrode.

[0060] In the above case, a plurality of through holes 211 for gas to pass through are provided on the sealing plate 21 corresponding to the opening of the "U"-shaped structural member 2. Charged particles can be adsorbed on the "U"-shaped structural member 2, and when the airflow passes through the through holes 211, the plate body where the through holes 211 are located can filter the particles in the airflow.

[0061] In this embodiment, an electrostatic dust removal field and a self-cleaning particulate matter purification device thereof are provided. By setting the dust collecting electrode and the discharge electrode of the electric field as a "U"-shaped structural member 2, and providing a through hole 211 on the "U"-shaped structural member 2, the plate body where the through hole 211 is located can filter the particulate matter in the airflow through the discharge electrode and the dust collecting electrode to cooperate with the dust removal, thereby achieving the dual effects of electrostatic adsorption and filtration of the particulate matter, and changing the arrangement of the discharge electrode and the dust collecting electrode of the electric field to make the overall spatial structure compact and small in size.

[0062] Furthermore, the self-cleaning particulate matter purification device is composed of a plurality of electrostatic dust removal electric fields 400 and a cleaning mechanism formed by combining a discharge electrode and a "U"-shaped structural member 2. The "U"-shaped structural member 2 is configured to ensure airflow and to filter the airflow during circulation. It can also electrostatically adsorb particulate matter in the airflow as it passes through. At the same time, the "U"-shaped structural member is configured to facilitate cleaning. The "U"-shaped structural member 2 is regularly cleaned by the cleaning mechanism 300 to ensure high purification and dust removal efficiency. It also improves the adsorption effect of the entire purifier. Regular cleaning also ensures the service life of the particulate matter purifier, making the performance of the particulate matter purifier stable. This solves the problem of traditional purification equipment being troublesome to disassemble and assemble during cleaning, saving labor costs.

[0063] Furthermore, the electric field frame body 1 includes two grounded conductive frames 11 arranged parallel and symmetrically on the front and rear sides, high-voltage conductive plates 12 respectively arranged on the outside of the grounded conductive frames 11, and four side frames 13 for connecting the grounded conductive frames 11 on the front and rear sides, and the four side frames 13 are respectively located at the four corners of the grounded conductive frames 11. The electric field frame body 1 also includes high-voltage conductive connecting rods 14 respectively arranged on the upper and lower sides of the "U"-shaped structural member 2 and arranged along the length direction (from front to back) of the side frames 13, and grounded conductive connecting rods 15 arranged on the side of the "U"-shaped structural member 2 away from the opening. There are two grounded conductive connecting rods 15, and the two grounded conductive connecting rods 15 are connected to the "U"-shaped structural member 2. The two ends of the high-voltage conductive connecting rods 14 are suspended through the center of the circular holes on the grounded conductive frames 11 on both sides and fixed to the high-voltage conductive plates 12, and can be fixed specifically by bolts. The front end of the high-voltage conductive connecting rod 14 is connected to the high-voltage end of the power supply via the first spring 31 of the power spring 3. The high-voltage end of the power supply is connected to the electrical control box 200 via a second insulator (not shown). The high-voltage conductive sheet 12 is insulated from the grounded conductive frame 11 by the first insulator 16. It should be noted that the power supply 203 is located inside the electrical control box 200. The power supply 203 is placed inside the electrical control box body 202 and can convert the 220V voltage into high voltage and transmit it to the electric field. Specifically, insulator mounting holes 204 are provided on the front side wall of the electrical control box body 202, corresponding to the first spring 31 and second spring 32 of the power spring 3. Four second insulators are inserted through the mounting holes and secured with plastic insulating bolts. A conductive screw is located at the center of each second insulator, connected to the positive and negative poles of the power supply 203, respectively. The voltage is transmitted through the second insulator to the conductive metal sheet near the side of the electrical control box 200. The free ends of the first spring 31 and second spring 32 are respectively connected to the corresponding high-voltage and low-voltage terminals in a contact manner. The high voltage and the low voltage grounding wire are insulated by insulators.

[0064] Furthermore, the discharge electrode includes a plurality of linear high-voltage electrodes 4 or a plurality of sawtooth sheet high-voltage electrodes (not shown in the figure) spaced between two high-voltage conductive connecting rods 14, and the specific arrangement of the discharge electrode is shown in FIG. Figure 9 shown.

[0065] Furthermore, the "U"-shaped structural member 2 includes a blocking plate 21 located at a position opposite to the opening, a first baffle 22 and a second baffle 23 arranged on both sides of the blocking plate 21, and a plurality of mounting components arranged on the side of the blocking plate 21 away from the opening. Each mounting component includes two parallel connecting plates 24, and the connecting plates 24 are fixedly connected to the blocking plate 21 by welding, and can fix the blocking plate 21 on the grounding conductive connecting rod 15. One end of the grounding conductive connecting rod 15 extends to the outside through the grounding conductive frame 11 on the front side, multiple mounting components and the grounding conductive frame 11 on the rear side, and the grounding conductive connecting rod 15 is connected to the low-voltage end of the power supply and is grounded. It should be noted that the "U"-shaped structural member 2 can be single-layer or multi-layer. It should be noted that the multi-layer structure is provided with structures of different materials such as filter cotton or filter fiber on the right or left side of the "U"-shaped structural member 2 for filtering. Filter cotton or filter fiber can also be provided between the double-layer "U"-shaped structural member 2 to achieve a better filtering effect.

[0066] It should also be noted that the blocking plate 21 can be any one of a linear, V-shaped, wavy or arc-shaped plate-shaped structure.

[0067] In addition, when only one "U"-shaped structural member 2 is installed in the electric field frame body 1, the sealing plate 21 can be directly connected to the grounded conductive frame 11 to form a "U"-shaped structural member 2 with the grounded conductive frames 11 on both sides, saving the first baffle 22, the second baffle 23 and the connecting plate 24, thereby reducing costs.

[0068] Furthermore, through-holes 211 are provided on the blocking plate 21 and / or the first baffle 22 and / or the second baffle 23. It should be noted that the through-holes 211 may be provided on only one or more of the blocking plate 21, the first baffle 22, or the second baffle 23. In this embodiment, the through-holes 211 are provided on all three plates: the blocking plate 21, the first baffle 22, and the second baffle 23. When air flows through the through-holes 211 on these three plates, the blocking plate 21, the first baffle 22, and the second baffle 23 can achieve the dual effects of electrostatic adsorption and filtration of particulate matter. Of course, some of the through-holes 211 may also be provided on the blocking plate 21, the first baffle 22, or the second baffle 23. Furthermore, the through-holes 211 on the blocking plate 21, the first baffle 22, and the second baffle 23 are of the same size, primarily to evenly distribute the airflow and improve the efficiency of particulate matter capture. At the same time, the purpose of providing the through holes 211 on both the first baffle 22 and the second baffle 23 is to increase the flow path of the flue gas and extend the flow time of the flue gas, thereby ensuring a better adsorption effect. Furthermore, the angle between the first baffle 22 and the second baffle 23 and the blocking plate 21 is between 95° and 115°. The purpose of setting it at a certain angle is to cooperate with the cleaning method of the cleaning unit 301 to clean the dead corners, thereby achieving better cleaning effect, simple design and low cost. Of course, the angle between the two baffles and the blocking plate 21 can also be set to 90° here, and the cleaning effect can be ensured by using a nozzle with a rotating function.

[0069] Furthermore, the discharge electrode is connected to the high-voltage conductive connecting rod 14 via a limiting structure. Specifically, the limiting member functions to control the axial position of the multiple linear high-voltage electrodes 4 on the high-voltage conductive connecting rod 14. In this embodiment, the limiting member can be a groove spaced axially along the high-voltage conductive connecting rod 14, with spring hooks positioned at both ends of the linear high-voltage electrodes 4 and engaging within the grooves for axial limiting. Alternatively, the limiting member can be an aluminum tube mounted on the high-voltage conductive connecting rod 14, with an annular groove formed between adjacent aluminum tubes to limit the axial position of the linear high-voltage electrodes 4. The first and second baffles of the "U"-shaped structural member 2 are secured to the grounded conductive connecting rod 15 via the aluminum tube. The aluminum tube serves as a limiting member (not shown). The discharge electrode comprises a group of linear high-voltage electrodes 4 arranged in parallel and at equal intervals and hung on the high-voltage conductive connecting rod 14. High-voltage direct current is passed through the electrode to form a high-voltage electric field, thereby charging particulate matter in the airflow. Alternatively, a fixing groove can be provided in the high-voltage conductive connecting rod 14 to secure the linear high-voltage electrodes 4. The dust collecting electrode consists of a "U"-shaped structural member 2 and two grounded conductive connecting rods 15. The right side of the "U"-shaped structural member 2 is connected to the mounting assembly. Specifically, the mounting assembly is two welded plates, that is, the "U"-shaped structural member 2 is welded to the two welding plates. The grounded conductive connecting rods 15 pass through the two welding plates on the rear side wall of the blocking plate 21 of the "U"-shaped structural member 2. An aluminum tube is installed between the grounded conductive connecting rods 15 and the "U"-shaped structural member 2 to achieve the effect of isolation and fixation, while ensuring that the "U"-shaped structural member 2 is evenly spaced and parallel on the grounded conductive connecting rods 15. Therefore, the charged particles are captured by the "U"-shaped structural member 2 under the attraction, achieving a good adsorption effect.

[0070] Furthermore, filters 500 are provided at both the air inlet 106 and the air outlet 107 .

[0071] In this embodiment, the cleaning mechanism 300 is disposed within the housing 100 and includes a plurality of cleaning units 301. Each cleaning unit 301 is disposed in a one-to-one correspondence with an electrostatic precipitator field 400 and is capable of periodically cleaning each electrostatic precipitator field 400. Of course, a cleaning unit 301 can also be disposed between two adjacent electrostatic precipitator fields 400, and a plurality of atomizing nozzles 3013 can be installed on both sides of the liquid distribution pipe 3012 of the cleaning unit 301, i.e., cleaning can be performed from both sides of the electrostatic precipitator field 400, greatly improving the cleaning effect.

[0072] Furthermore, the cleaning mechanism 300 includes an "L"-shaped liquid supply pipe 3011, and the horizontal portion of the liquid supply pipe 3011 is arranged along the front to rear direction of the box body 100, and the vertical portion of the liquid supply pipe 3011 passes through the top wall 105 upward and is connected to the box body for externally containing cleaning liquid. The cleaning mechanism 300 also includes a plurality of liquid distribution pipes 3012 connected to the liquid supply pipe 3011, and the plurality of liquid distribution pipes 3012 are arranged at intervals on the liquid supply pipe 3011. The liquid distribution pipes 3012 are arranged along the longitudinal direction of the "U"-shaped structural member 2 of the electrostatic precipitator field 400. A plurality of atomizing nozzles 3013 are spaced apart on the outer wall of the liquid distribution pipe 3012 close to one side of the "U"-shaped structural member 2, and the atomizing nozzles 3013 can spray water toward the "U"-shaped structural member 2. Three atomizing nozzles 3013 are evenly distributed on each liquid distribution pipe 3012, which can achieve full coverage of the electric field and a more comprehensive cleaning effect.

[0073] It should be noted that one end of the liquid supply pipe 3011 is connected to a water pump, which draws external cleaning liquid (water in this embodiment) and delivers the water through the liquid supply pipe 3011 to the liquid distribution pipe 3012. The water is then sprayed through the atomizing nozzle 3013 to spray clean the electrostatic dust removal field 400. It should be emphasized that although the cleaning mechanism 300 sprays clean water, because this embodiment performs regular cleaning, this cleaning method can meet the subsequent demand for particulate matter adsorption. Compared with existing manual cleaning methods, this method saves a lot of work and cleaning costs.

[0074] Furthermore, the housing 100 further includes a track support 600 disposed on the inner side of the bottom wall 103 of the housing 100 and a sliding track 700 disposed on the track support 600. The track support 600 extends through the bottom wall 103 from front to back, the sliding track 700 is the same length as the track support 600, and the bottom of the electric field frame body 1 of the electrostatic precipitator 400 is slidably connected to the sliding track 700. The track support 600 is a U-shaped groove. The track support 600 is located at the upper end surface of the bottom wall 103 and the lower end surface of the top wall 105 of the box body 100, and the track support 600 on the upper and lower end surfaces are correspondingly arranged. The track support 600 is welded and fixed to the box body 100. The sliding track 700 is placed on the track support 600 and is arranged in parallel from the air inlet 106 to the air outlet 107, which is used to place the electrostatic dust removal field 400. Among them, four small tracks are formed between the sliding track 700 and the track support 600. The small track near the air inlet 106 and the air outlet 107 is used to place the filter net, the purpose of which is to prevent large foreign matter from entering the purifier with the air flow; the electrostatic dust removal field 400 is placed into the box body 100 from the front of the box body 100. By setting the sliding track 700, it can be ensured that the electrostatic dust removal field 400 and the filter net 500 will not shake or deviate, thereby ensuring the effect of adsorption and dust removal.

[0075] In this embodiment, a controller is located within and electrically connected to the electrical control box 200 to control the power supply to the electrostatic precipitator 400. The controller is also electrically connected to the water pump of the cleaning mechanism 300 to control the cleaning of the electrostatic precipitator 400. The controller, which can be comprised of a PLC or a single-chip microcomputer, automatically controls the power supply, fan, and water pump of the electrostatic precipitator 400. When the restaurant closes for the evening, the controller cuts off the power supply to the electrostatic precipitator 400 and controls the water pump to turn on, pumping water through the spray cleaning device to self-clean the field. After 10 minutes of cleaning (the cleaning time can be adjusted based on actual conditions), the spray cleaning device turns off and the controller automatically controls the fan to dry the field. The specific drying time can be adjusted based on actual conditions to ensure that the purifier's insulation components are completely dry and do not affect subsequent use. Of course, to ensure proper daytime operation of the purifier, this purifier is typically cleaned regularly at night.

[0076] It should be noted here that the cleaning liquid includes water, but is not limited to water. In order to improve the cleaning effect, the cleaning liquid can also be alkaline solution or steam to improve the cleaning effect.
