Electrostatic precipitator is a kind of gas dedusting method. Its principle is: when the dust-containing gas passes through a high-voltage electrostatic field, it is electrically separated, and after the dust particles and negative ions are negatively charged, they tend to discharge and deposit on the surface of the anode. That is, in the strong electric field, the air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of running to the positive electrode, so that the dust particles are negatively charged and adsorbed to the positive electrode to be collected.

Further, in the description of the present disclosure, unless otherwise specified, "plurality" means two or more.

The electrostatic precipitator 1 according to the embodiment of the present disclosure will be described below with reference to the accompanying drawings.

As shown in FIGS. 1-12 , the electrostatic precipitator 1 according to the embodiment of the present disclosure includes a plurality of electrode units 100 , and the plurality of electrode units 100 at least include a high-potential unit 130 and a low-potential unit 140 , and the plurality of electrode units 100 are spaced apart from each other. The high-potential units 130 and the low-potential units 140 are arranged alternately, in other words, some electrode units 100 can be used as high-potential units 130, and some electrode units 100 can be used as low-potential units 140, that is, electrodes adjacent to the high-potential units 130 The unit 100 is a low-potential unit 140, and the electrode unit 100 adjacent to the low-potential unit 140 is a high-potential unit. For example, the arrangement of the plurality of electrode units 100 is: a high-potential unit 130, a low-potential unit 140, a high-potential unit 130. The low-potential units 140 are alternately arranged in sequence. A dust removal air duct 191 is formed between adjacent electrode units 100 .

Wherein, each electrode unit 100 is annular and includes a conductive portion 110 and an insulating portion 120. The conductive portion 110 includes a conductive protrusion 111 and an electric field generator 112. The insulating portion 120 covers a part of the electric field generator 112. The circumferential directions of the adjacent high-potential cells 130 and the low-potential cells 140 extend in a ring shape.

It can be understood that the conductive bump 111 refers to the part of the conductive portion 110 used to achieve electrical conduction. The electric field generator 112 refers to a portion of the conductive portion 110 for generating an electric field.

According to the electrostatic precipitator 1 of the present disclosure, the electric field generators 112 are covered by the insulating portion 120 , so that the electric field generators 112 of the adjacent electrode units 100 are separated by the insulating portion 120 , on the one hand, electricity generation between the electrode units 100 is avoided. The corona discharge avoids breakdown and produces ozone, solves the problem of ozone from the source of ozone generation, reduces the risk of electric shock accidents, and greatly improves the safety of use. On the other hand, the coating method is adopted. The conductive part 110 and the insulating part 120 can be formed as a whole, which is beneficial to simplify the assembly, and each electrode unit 100 is formed as an independent whole, so that it is beneficial to the individuality of each electrode unit 100 in production or use. Replacement, for example, if a certain electrode unit 100 is found to be defective during production, it can be replaced individually, without having to deal with multiple electrode units 100 or the overall dust removal device 1, which indirectly improves the yield of the product and saves money. Production cost, and during use, since a single electrode unit 100 can be replaced, maintenance and upkeep during use are facilitated.

Since a high-voltage electric field can be generated between the adjacent electrode units 100 of the electrostatic precipitator 1, air molecules can be ionized into positive ions and negative ions through the high-voltage electric field. When the negative ions are in contact with bacteria, molds, viruses, etc., the negative ions themselves carry Excess electrons will destroy the molecular protein structure in bacteria, molds, viruses, etc., causing structural changes (reversed protein polarity) or energy transfer in bacteria, molds, viruses, etc., so that microorganisms such as bacteria and viruses die. Therefore, the electrostatic precipitator 1 has a sterilization effect, thereby improving the cleanliness of the air.

By configuring each electrode unit 100 in a ring shape, air can enter the electrostatic precipitator 1 from various angles in the circumferential direction of the electrostatic precipitator 1, and it is ensured that the air can fully contact the electrode unit 100, thereby improving the efficiency of the electrostatic precipitator 1. Therefore, the dust removal effect of the electrostatic precipitator 1 is good. Moreover, since each electrode unit 100 is annular, when the dust removal area of the electrode unit 100 is increased, the electrode units 100 can be extended to the surrounding at the same time, thus ensuring the dust removal area and the occupied space of the electrostatic precipitator 1 is small.

In this way, the electrostatic precipitator 1 according to the embodiment of the present disclosure takes into account the area of dedusting and sterilization and the utilization of space, and can realize all-angle dedusting and sterilization in its circumferential direction, and has the advantages of good dedusting effect and sterilization and high safety.

According to some specific embodiments of the present disclosure, as shown in FIGS. 4 and 5 , the insulating portion 120 covers the entire electric field generator 112 , so that the probability of discharge between adjacent electrode units 100 is lower, which further reduces the generation of ozone. The probability of electric shock accidents is reduced, and the reliability of the electrostatic precipitator 1 is greatly improved.

According to some specific embodiments of the present disclosure, as shown in FIGS. 1-3 , the electrode units 100 are arranged along the axial direction of the plurality of electrode units 100 . As a result, the wind resistance can be reduced, the dust collection and sterilization area can be increased, and the occupied space of the electrostatic precipitator 1 can be smaller.

According to some specific embodiments of the present disclosure, as shown in FIGS. 4 and 5 , the conductive parts 110 and the insulating parts 120 of the plurality of electrode units 100 are injection-molded. In this way, the conductive part 110 and the insulating part 120 form a complete whole, which not only simplifies the assembly, but also makes the structure more stable, and can use the mold to ensure that the thickness of the electrode unit 100 is uniform and controllable, which is beneficial to mass production and spacing consistency, thereby electrostatic precipitation. All parts of the device 1 have the same wind resistance, which can improve the uniformity of dust removal.

Further, the conductive parts 110 and the insulating parts 120 of the plurality of electrode units 100 are integrally injection-molded. In this way, the production efficiency of the electrostatic precipitator 1 is higher.

According to some specific embodiments of the present disclosure, as shown in FIG. 4 and FIG. 5 , the conductive part 110 is a conductive plastic part. In this way, it is easy to form each electrode unit 100 into a ring shape, the processing is simple, and the mass production is facilitated. In addition, the conductive plastic parts are light in weight, have good stretchability, elasticity and flexibility, and are easy to form. At the same time, the conductive plastic parts have the advantages of metal, such as good electrical conductivity.

It can be understood that the annular electrode unit 100 saves more space than the non-circular electrode unit 100 after being stacked, and can further reduce the size of the electrostatic precipitator 1 while taking into account the dust accumulation area and the sterilization effect. occupied space. Moreover, since the outer diameters of the annular electrode units 100 along the radial direction are the same, when a plurality of electrode units 100 are installed, there is no need for circumferential alignment and positioning, while the length of the non-circular electrode units 100 along the radial direction is different. They are exactly the same. Therefore, when multiple electrode units 100 are installed, they need to be aligned and positioned in the circumferential direction, that is, the electrode units 100 with a circular ring shape are more convenient to install.

According to some specific embodiments of the present disclosure, as shown in FIGS. 4 and 5 , one of the adjacent electrode units 100 is provided with a positioning ring 150 , and the other is provided with a positioning protrusion 160 inserted into the positioning ring 150 .

For example, the positioning ring 150 surrounds the groove portion, and the positioning ring 150 is arranged along the circumferential direction of the electrode unit 100 . Adjacent electrode units 100 are assembled together through the positioning protrusions 160 and the positioning ring 150, so that a plurality of electrode units 100 can be fixed together to form a whole, and due to the positioning of the positioning protrusions 160 and the positioning ring 150, it can be reliably The distance between adjacent electrode units 100 is defined to ensure the consistency of the dust removal air ducts 191 .

In addition, the positioning ring 150 is provided on one side in the thickness direction of the electrode unit 100 , the positioning protrusion 160 is provided on the other side in the thickness direction of the electrode unit 100 , and the positioning ring 150 and the positioning protrusion 160 are provided on the insulation of the electrode unit 100 This can not only further prevent the occurrence of corona discharge in the electrostatic precipitator 1, reduce the probability of ozone generation and electric shock, but also facilitate processing and assembly, and improve assembly efficiency.

Wherein, the plurality of first conductive protrusions and the plurality of the second insulating protrusions face one side in the radial direction of the plurality of electrode units 100 , the plurality of the first insulating protrusions and the plurality of the second insulating protrusions The conductive protrusions face the other side in the radial direction of the electrode unit 100 .

It can be understood that the first conductive protrusions and the second insulating protrusions are alternately arranged, for example, the first conductive protrusions, the second insulating protrusions, the first conductive protrusions, the The two insulating protrusions are alternately stacked in this manner. The second conductive bumps and the first insulating bumps are alternately arranged, for example, the second conductive bumps, the first insulating bumps, the second conductive bumps, and the first insulating bumps are like this Alternately spaced stacks.

The second conductive protrusions are matched with a plurality of the first insulating protrusions. Wherein, the first positioning member 200 and the second positioning member 300 are made of conductive materials. Therefore, the first positioning member 200 and the second positioning member 300 are used to fix the high-potential conductive member 230 and the low-potential conductive member 330 respectively, and realize Connection to a plurality of electrode units 100 .

Further, the first positioning member 200 is provided with a plurality of first positioning teeth 210 and a first tooth slot 220 is formed between adjacent first positioning teeth 210 .

The second positioning member 300 is provided with a plurality of second positioning teeth 310 and a second tooth slot 320 is formed between adjacent second positioning teeth 310 . Two positioning members 300, each of the second positioning teeth 310 is fitted between the adjacent second conductive protrusions and the first insulating protrusions.

For example, the widths of the tooth tips of the first positioning teeth 210 and the second positioning teeth 310 may be gradually reduced to facilitate assembly. Therefore, the first positioning member 200 and the second positioning member 300 can carry the high-potential conductive member 230 and the low-potential conductive member 330 respectively to be connected to the plurality of electrode units 100 , thereby improving the structural stability and electrical properties of the plurality of electrode units 100 . connection reliability.

Since the insulating portion 120 fully covers the electric field generator 112 of the conductive portion 110 , the thickness of the electric field generator 112 is smaller than that of the insulating portion 120 , and the thickness of the conductive protrusion 111 can be set to be the same as the thickness of the electric field generator 112 . In this way, the production and processing of the conductive portion 110 is facilitated, and the production cost and structural strength are taken into consideration. And the first insulating protrusion and the second insulating protrusion are formed by the insulating portion 120, so the thickness of the first insulating protrusion and the second insulating protrusion may be larger than that of the first conductive protrusion and the second conductive protrusion. up thickness. In this way, the connection strength between the plurality of potential units 23 and the first positioning member 200 and the second positioning member 300 is ensured, thereby improving the overall structural stability of the electrostatic precipitator 1 . In addition, by setting the slot width of the low-potential cogging to be larger than the slot width of the high-potential cogging, it can not only ensure that the distance between the high-potential unit 130 and the low-potential unit 140 in the thickness direction of the electrode unit 100 is fixed, but also facilitates assembly during assembly. Distinguishing the correspondence between the insulating protrusions 121 and the conductive protrusions 111 and the high-potential cogging and the low-potential cogging reduces the assembly difficulty and improves the assembly speed.

Since the first positioning member 200 and the second positioning member 300 need to ensure production cost, structural strength, Due to the influence of the structures of the first positioning member 200 and the second positioning member 300 , the electrical conductivity of the first positioning member 200 and the second positioning member 300 is poor. Therefore, by arranging the high-potential conductive member 230 and the low-potential conductive member 330 , it can ensure that The electric field strengths of each part of the first positioning member 200 and the second positioning member 300 are similar and stable. In this way, the positioning member 30 wraps the conductive member along the circumferential direction of the conductive member to further ensure that the electric fields of each part of the positioning member are closer and more stable.

By arranging the air guide 630 , the airflow direction of the electrostatic precipitator 1 can be realized from the circumferential direction of the air inlet, and then the air is discharged from the cover plate provided with the air guide 630 .

Of course, in other embodiments of the present disclosure, the air can also be taken in from the air guide 630 , and then the air can be discharged from the circumferential direction of the electrostatic precipitator 1 .

In addition, the contact area between the cover plate and the protective cover is larger, and the cover plate can stop the protective cover in the radial and axial directions of the electrostatic precipitator 1 , which further increases the overall structural strength of the electrostatic precipitator 1 .

According to some specific embodiments of the present disclosure, as shown in FIGS. 1 and 3 , the electrostatic precipitator 1 further includes a high-potential conductive contact piece 640 and a low-potential conductive contact piece 650 , and the high-potential conductive contact piece 640 is located on the first cover plate 600 and one side of the second cover plate 700 facing away from the electrode unit 100 , the high-potential conductive contact piece 640 is connected to the high-potential conductive member 230 , and the low-potential conductive contact piece 650 is located in the first cover plate 600 and the second cover plate 700 On the side of the one facing away from the electrode unit 100 , the low-potential conductive contact piece 650 is connected to the low-potential conductive member 330 .

The following description takes the example that the high-potential conductive contact piece 640 and the low-potential conductive contact piece 650 are located on the first cover plate 600 :

The first cover plate 600 may be provided with an air guide port 630 , or the first cover plate 600 may not be provided with an air guide port 630 . When the electrostatic precipitator 1 is applied, the high-potential conductive contact piece 640 and the low-potential conductive contact piece 650 can be connected to the power supply, which facilitates the electrical connection of the electrostatic precipitator 1, and the connection between the electrostatic precipitator 1 and the power supply can be realized through the contact piece.

Further, a side of the first cover plate 600 facing away from the plurality of electrode units 100 is provided with a mounting groove 740, and the high-potential conductive contact piece 640 and the low-potential conductive contact piece 650 are located in the mounting groove 740.

For example, the installation grooves 740 are provided at intervals along the radial direction of the electrode unit 100 , at least one of the plurality of installation grooves 740 is installed with a high-potential conductive contact 640 , and at least one of the plurality of installation grooves 740 is installed with a low-potential The conductive contact piece 650 can prevent a short circuit between the high-potential conductive contact piece 640 and the low-potential conductive contact piece 650 , thereby improving the reliability of the electrostatic precipitator 1 . In this way, by setting the mounting groove 740, the relative positions between the high-potential conductive contact piece 640 and the low-potential conductive contact piece 650 and the cover plate can be fixed, the relative displacement between the contact piece and the cover plate can be prevented, and the contact piece can be quickly determined The installation position is improved, and the assembly efficiency is improved.

This makes production more efficient.

In addition, the first cover plate 600 is provided with a wire hole (not shown in the figure), the wire between the high-potential conductive contact piece 640 and the high-potential conductive member 230 passes through the wire-through hole, and the low-potential conductive contact piece 650 and The wires between the low-potential conductive members 330 pass through the wire holes. In this way, the electrical connection between the contact piece and the conductive member is facilitated, the length of the wire is shortened, the wear probability of the wire is reduced, and the safety of the wire is improved.

It can be understood that there may be multiple, for example, two vias, and one of the two vias is used to pass the wires of the high-potential conductive member 230 and the other is used to pass the low-potential conductive member 330 . The one of the two wire vias may be disposed adjacent to the high-potential conductive member 230 and the other may be disposed adjacent to the low-potential conductive member 330 . In this way, the wires of the high-potential conductive member 230 are separated from the wires of the low-potential conductive member 330 , which can reduce the mutual interference between the two wires and ensure that the voltages of the high-potential conductive member 230 and the low-potential conductive member 330 are stable. In addition, by placing the wire via holes adjacent to the high-potential conductive member 230 and the low-potential conductive member 330 respectively, the length of the wire can be further shortened.

Further, as shown in FIG. 1 and FIG. 3 , the first cover plate 600 is provided with a holding portion 670 , and the holding portion 670 extends outward along the radial direction of the plurality of electrode units 100 .

The following is an example of the handle 910 being disposed on the first cover plate 600:

There can be multiple handles 910, and each handle 910 can be a part of a ring. Multiple handles 910 can be arranged to facilitate the movement of the electrostatic precipitator 1 as a whole, reduce the force of each handle 910, and improve the handle 910. overall service life. Each handle 910 is set as a part of an annular shape, so that each handle 910 is evenly stressed and the service life of the handle 910 is improved. In addition, the shape of the receiving groove 750 can be adapted to the shape of the handle 910. For example, the handle 910 is a part of an annular shape, and the receiving groove 750 can be an annular groove extending circumferentially around the first cover plate 600. The annular groove can be provided with on the outer peripheral side of the first cover plate 600 . The handles 910 can be installed on opposite sides of the first cover plate 600, and the two ends of the handle 910 are provided with plug-in posts, and the outer peripheral surface of the first cover plate 600 is provided with plug-in holes.

In addition, when the handle 910 is in the hidden state, the handle 910 is located in the receiving slot 750, and the handle 910 does not exceed the surface of the first cover plate 600 facing away from the electrode unit 100, which not only ensures the neat appearance of the electrostatic precipitator 1 , and can further prevent the electrostatic precipitator 1 from colliding with the outside world. When the handle 910 is in the working state, the handle 910 is located outside the storage slot 750 , and the handle 910 can be held at this time, which not only facilitates the overall movement of the electrostatic precipitator 1 , but also facilitates cleaning of the electrostatic precipitator 1 .

According to some specific embodiments of the present disclosure, as shown in FIG. 1 , the electrostatic precipitator 1 further includes a first fixing member 800 and a second fixing member (not shown in the figure).
