Description

A purification unit Technical Field

[0001] The present invention relates to the field of gas purification, and in particular to a purification unit. Background Art

[0002] As people's environmental awareness is increasing, the recognition and demand for purification of pollutants in air gases (including but not limited to flue gas, dust, VOCs and engine exhaust) are also increasing. Therefore, more and better purification technologies are gradually being installed and used in vehicles, factories, and home environments. Among these purification technologies, electrostatic dust removal and adsorption technology has a very common application. The principle of electrostatic dust removal and adsorption technology is that the gas is ionized when passing through the electrostatic field. After the particulate matter in the gas combines with the charged ions, it tends to move to the electrode with the opposite polarity of the charged ions and deposits. It can be seen that the particle removal rate is related to the charging efficiency of the particles. However, the existing technology still has the problem of complex structure of the gas particulate purification device, which not only has high production costs, but also has technical problems of poor particle removal rate and purification effect.

[0097] The beneficial effects of the present invention are:

[0098] 1. The gas particulate matter purification device provided by the present invention can effectively remove water droplets, dust, and viruses in the gas. The first purification device can mainly remove water droplets, and the second purification device can effectively remove dust and viruses in the gas. Since the first purification device effectively removes water in the gas, the working efficiency of the second purification device is improved.

[0099] 2. The first purification device provided by the present invention is used to remove particulate matter in the gas, including but not limited to water droplets, viruses, bacteria, dust, radioactive aerosols and other pollutants. It has the characteristics of high temperature resistance and can be applied to automobile exhaust treatment, power plant exhaust purification and other environments.

[0100] 3: The first discharge electrode of the first purification device provided by the present invention includes multiple groups of circumferentially arranged discharge beam assemblies, and the discharge beam in the discharge beam assembly includes thousands of metal wires and / or conductive non-metallic wires. The discharge beam is fixed on the discharge rod and is similar to a brush. The discharge beam adopts corona discharge, and the tip of each fiber filament at the free end is a discharge point, which significantly improves the discharge effect, increases the charge and charging efficiency of particulate matter in the gas, and effectively reduces it to almost no ozone generation.

[0101] 4. The discharge electrode in the first purification device provided by the present invention also has the following advantages:

[0102] Under the same purification efficiency requirements, compared with the purification device composed of an electrode rod or an electrode wire and an adsorption electrode for purifying gas particulate matter, when the first discharge electrode of the present invention is combined with the same adsorption electrode, the voltage required to be applied in the present invention is much smaller than the voltage required for an electrode rod or an electrode wire, which has the advantages of low energy consumption and low cost, thereby effectively reducing the generation of ozone to almost no level.

[0103] Compared to installing one or more discharge beams in a single location, the first discharge electrode provided by the present invention incorporates at least one discharge beam assembly on a single electrode rod. This extends the discharge length in the longitudinal direction, rapidly improving the dust removal efficiency of the purification device. Each discharge beam assembly at the same location includes multiple circumferentially distributed discharge beams. This circumferential distribution around the electrode rod ensures a higher discharge density and more uniform discharge in the transverse direction. The longitudinal and transverse extension of the discharge electrode charges more particulate matter in the gas throughout the hollow adsorption electrode space, enhancing the charging effect and, in turn, the adsorption effect, significantly improving the gas purification rate. Furthermore, this discharge electrode structural design also effectively expands the adsorption electrode area of ​​the purification device, significantly improving the adsorption purification capability.

[0104] In the first discharge electrode provided by the present invention, there is a case in which a discharge beam is further provided at one or both ends of the electrode rod. After voltage is applied, the discharge beam at the end generates positive ions or negative ions through corona discharge. The direction of the discharge beam is consistent with the direction of the airflow. When the gas flows through the first discharge electrode, the charging efficiency of the particulate matter in the gas can be further improved, thereby improving the gas purification efficiency.

[0105] 5. The first type of second purification unit having the first conductive fixing mechanism has the following advantages:

[0106] The first conductive fixture is located at the gas outlet of the second purification unit. The gas flowing through the first conductive fixture is clean, preventing contamination. The gas inlet of the second purification unit, where dust is most likely to accumulate, lacks any connecting structure. This ensures a relatively stable electric field formed between the first and second electrodes for adsorbing particulate matter, making it less susceptible to short circuits. When the airflow path of the second purification unit is perpendicular to the bottom surface, if water mist is absorbed by the second purification unit, the water droplets can flow down under the action of gravity, leaving the first conductive fixture clean and less susceptible to short circuits.

[0107] 6. Both the second type and the second type of second purification unit utilize a plug-in design, simplifying the structure of the second purification unit and preventing short circuits. Furthermore, the plug-in design incorporates an insulating positioning bracket or insulating positioning connection mechanism, ensuring that when multiple first and second electrodes are installed in a mutually inserted manner, the distance between the first and second electrodes remains constant.

[0132] Example 1

[0133] One embodiment of the present invention provides a gas particulate matter purification device. Referring to FIG1 , the gas particulate matter purification device 1 includes a first purification device 10 and a second purification device 20 arranged sequentially along the airflow direction. The first purification device 10 includes a first adsorption electrode 11 and a first discharge electrode 12 that generate a first electric field for adsorbing particulate matter. The first adsorption electrode 11 is a hollow tube, and the first discharge electrode 12 passes through the first adsorption electrode 11 and is arranged along the central axis of the first adsorption electrode 11. The first discharge electrode 12 includes an electrode rod 121 and at least one discharge beam assembly 123. The discharge beam assembly 123 includes multiple first discharge beams 122 circumferentially arranged on the electrode rod 121. In one embodiment, the discharge beam assembly 123 includes one to six first discharge beams 122. The ends of the first discharge beams 122 face the first adsorption electrode 11, and there is a certain distance between the ends of the first discharge beams 122 and the inner wall of the first adsorption electrode 11.

[0134] In one embodiment of the present invention, the first adsorption electrode 11 is a hollow tube, and the cross section of the hollow tube is polygonal or circular.

[0135] In the present invention, in the first purification device, the first discharge electrode and the first adsorption electrode are electrically connected to the two poles of the power supply, that is, the first discharge beam is used to discharge after voltage is applied, so that the gas is ionized, the particulate matter in the gas is charged, and the charged particulate matter is adsorbed by the first adsorption electrode, thereby purifying the particulate matter.

[0136] The second purification device 20 includes a second purification unit 22 . The second purification unit 22 includes a first electrode and a second electrode. The second electrode is grounded and forms a second electric field with the first electrode for adsorbing particulate matter.

[0137] Through such a design, the gas particulate purification device 1 can be used in industrial chimneys to purify gas particulates. The gas particulate purification device 1 can effectively remove water droplets, dust, viruses and other particles in the flue gas. The gas enters the first purification device 10 and the second purification device 20 for purification in turn. The first purification device 10 can mainly remove water droplets and other particles, and the second purification device 20 can effectively remove dust, viruses and other particles in the gas. At the same time, since the first purification device 10 effectively removes water in the gas, the working efficiency of the second purification device 20 is improved.

[0138] In one embodiment of the present invention, referring to FIG1 , the second purification device 20 further includes a third discharge beam 21. The third discharge beam 21 is positioned in front of the second purification unit 22 along the airflow direction. The third discharge beam 21 includes a plurality of metal wires and / or conductive non-metallic wires. The metal wires or conductive non-metallic wires of the third discharge beam 21 face the second purification unit 22, and a certain distance exists between the top ends of the metal wires or conductive non-metallic wires of the third discharge beam 21 and the second purification unit 22. Thus, the second purification device 20 includes the second discharge beam 21 and the second purification unit 22, which are positioned along the airflow direction. The second purification unit 22 includes a first electrode 221 and a second electrode 222. The second electrode 222 is grounded and forms an electric field with the first electrode 221 for particle adsorption. The second discharge beam 21 is electrically connected to a DC high-voltage power supply, and the discharge of the second discharge beam 21 charges particles in the gas. The charged particles enter the second purification unit 22 for particle adsorption, significantly improving particle adsorption efficiency.

[0139] In the present invention, the second purification unit includes a plurality of electrically connected first electrodes and a plurality of electrically connected second electrodes. The first electrodes and the second electrodes are arranged in an interlaced manner to form a second electric field for adsorbing particulate matter. The first and second electrodes can be electrically connected to the two poles of a power supply, one of which can be grounded. The first and second electrodes form a second electric field for adsorbing particulate matter. That is, the first electrode is connected to the positive pole of the power supply and the second electrode is connected to the negative pole of the power supply, or the second electrode is connected to the positive pole of the power supply and the first electrode is connected to the negative pole of the power supply. In the present invention, there are two situations: in the first situation, the first electrode acts as a discharge electrode to discharge and charge the particulate matter, and the second electrode acts as an adsorption electrode to adsorb the charged particulate matter; in the second situation, the second electrode acts as a discharge electrode to discharge and charge the particulate matter, and the first electrode acts as an adsorption electrode to adsorb the charged particulate matter. In the second purification unit, the gas enters the gas flow channel between the two electrodes, and the discharge electrode discharges to ionize the gas and charge the particulate matter. If the discharge electrode is connected to the negative electrode of the power supply and the adsorption electrode is connected to the positive electrode of the power supply (the adsorption electrode can be grounded), in this process, the particulate matter is negatively charged and adsorbed on the adsorption electrode. The particulate matter includes but is not limited to water droplets, viruses, bacteria, radioactive aerosols and other pollutants. After the second electric field treatment, the pollutants in the gas are removed to obtain sterile, radiation-free and virus-free clean gas, thereby achieving the effect of purifying the gas.

[0140] In one embodiment of the present invention, the first electrode and the second electrode of the second purification unit are both flat plates, and the first electrode and the second electrode are arranged in parallel and staggered. A gas flow channel is formed between the first electrode and the second electrode to allow gas to pass through for electric field treatment. The specific structure of the second purification unit can be referred to Example 2.

[0141] In one embodiment of the present invention, the first electrode and the second electrode of the second purification unit are both hollow tubes with different diameters. The first electrode and the second electrode are coaxially mounted and the first electrode and the second electrode are alternately arranged in sequence from the axis to the periphery. A gas flow channel is formed between the first electrode and the second electrode to allow gas to pass through for electric field treatment. The specific structure of the second purification unit can refer to Example 3 or Example 4.

[0142] In one embodiment of the present invention, when the first and second electrodes of the second purification unit are both hollow tubes of different diameters, multiple first electrodes and multiple second electrodes are coaxially mounted and alternately arranged from the axis toward the periphery, a power supply and / or rechargeable battery is disposed within the hollow tube with the smallest diameter, and the power supply and / or rechargeable battery supplies power to the gas particulate matter purification device. When the hollow tube with the smallest diameter in the second purification unit is an inner adsorption electrode or an inner induction electrode, the power supply and / or rechargeable battery is disposed within the cylinder of the inner adsorption electrode or the inner induction electrode.

[0143] In one embodiment of the present invention, the gas particulate matter purification device further includes a fan, which is disposed on a side adjacent to the air outlet of the second purification unit. That is, along the airflow direction, the fan is disposed behind the second purification device, and gas flows through the second purification unit of the second purification device and is then discharged through the fan.

[0144] In one embodiment of the present invention, in the first purification device 10 , the electrode rod 121 of the first discharge electrode 12 is disposed along the central axis of the first adsorption unit 11 .

[0145] In one embodiment of the present invention, as shown in FIG1 , in the first discharge electrode 12 of the first purification device 10 , multiple first discharge beams in the same discharge beam assembly are evenly arranged in the same circumferential direction around the electrode rod.

[0146] In one embodiment of the present invention, the discharge beam assembly includes 1-15 first discharge beams. Preferably, the number is 1-3, or 3-7, or 8-15. Typical but non-limiting numbers of the first discharge beams are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15.

[0147] In one embodiment of the present invention, 3-21 discharge beam assemblies are provided per meter on the electrode rod. Preferably, 3-7 discharge beam assemblies are provided per meter on the electrode rod, or 3-16 discharge beam assemblies are provided per meter on the electrode rod, or 3-18 discharge beam assemblies are provided per meter on the electrode rod, or 16-21 discharge beam assemblies are provided per meter on the electrode rod. Typical but non-limiting numbers of discharge beam assemblies provided per meter on the electrode rod are 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, or 21. It should be noted that the distances between adjacent discharge beam assemblies may be equal or unequal.

[0148] It should be noted that the length of the electrode rod, the distance between the discharge beam assemblies on the electrode rod, the number of the discharge beam assemblies, and the number of first discharge beams in the discharge beam assemblies can be set according to actual needs.

[0149] In one embodiment of the present invention, the first discharge beam in the discharge beam assembly is arranged at a certain angle to the axis of the electrode rod. Preferably, as shown in FIG1 , the first discharge beam 122 is arranged at 90° to the axis of the electrode rod 121 .

[0150] In one embodiment of the present invention, one end of the multiple metal wires and / or non-metal wires of the first discharge bundle is fixed together to form a fixed end, and the other end is a free end. The fixed end of the first discharge bundle is fixed to the electrode rod 121. In this embodiment, the fixed ends of the multiple first discharge bundles 122 in a discharge bundle assembly 220 are fixed to the same circumference of the electrode rod 121 and are evenly arranged.

[0151] In one embodiment of the present invention, a second discharge beam is provided on at least one end of the electrode rod, and the second discharge beam is provided parallel to the axis of the electrode rod. In the present invention, a second discharge beam can be provided on one end of the electrode rod or on both ends.

[0152] In one embodiment of the present invention, as shown in FIG1 , a second discharge beam is provided at the end of the electrode rod 121 close to the second purification device 20 . In this case, the second discharge beam can replace the third discharge beam 21 in the second purification device 20 described above.

[0153] In one embodiment of the present invention, as shown in Figure 2, a second discharge beam 21' is provided at one end of the electrode rod 121, near the inlet for the gas to be treated. This design places a discharge beam at the end of the discharge electrode rod near the gas inlet. When voltage is applied, the discharge beam at this end generates positive or negative ions through corona discharge. This discharge beam aligns with the direction of the gas flow, further enhancing the efficiency of charging particulate matter in the gas as it flows through the discharge electrode, thereby improving gas purification efficiency.

[0154] In the present invention, the first discharge beam includes multiple metal wires and / or conductive non-metallic wires (discharge material). One end of the multiple metal wires and / or non-metallic wires is fixed together to form a fixed end, and the other end is a free end. The multiple metal wires and / or non-metallic wires at the free end are in a dispersed state. The free end of the discharge beam faces the inner wall of the first adsorption electrode, and there is a certain distance between the free end of the first discharge beam and the inner wall of the first adsorption electrode. Preferably, the distance between the free end of each first discharge beam and the inner wall of the first adsorption electrode is the same.

[0155] In the present invention, the electrode rod is made of conductive material, and the material of the electrode rod and the material of the discharge bundle can be the same or different. For example, the electrode rod is made of stainless steel, and the discharge bundle is composed of multiple stainless steel fiber filaments; or the electrode rod is made of stainless steel, and the discharge bundle is composed of multiple carbon fiber filaments.

[0156] In the present invention, multiple first discharge beams are fixed on the electrode rod. Under this design, one or more discharge beams are fixed, and secondly, when the electrode rod is electrically connected to one pole of the power supply, the discharge beam is also connected to the power supply. In the case of multiple discharge beams, multiple discharge beams can be connected to one power supply at the same time, which is simple and convenient in structure.

[0157] In the present invention, at least one discharge beam assembly is provided on an electrode rod, extending the discharge length in the longitudinal direction and rapidly improving the dust removal efficiency of the purification device. Each discharge beam assembly includes multiple discharge beams distributed circumferentially. This circumferential distribution around the electrode rod ensures a higher discharge density and more uniform discharge in the lateral direction. The longitudinal and lateral extension of the discharge electrode charges more particulate matter in the gas throughout the hollow adsorption electrode space, enhancing the charging effect, thereby improving the particle adsorption effect and significantly increasing the gas purification rate. Furthermore, this discharge electrode structural design also effectively expands the adsorption electrode area of ​​the purification device, significantly improving the adsorption purification capacity.

[0158] In the present invention, the structures of the first discharge beam, the second discharge beam, and the third discharge beam, and the materials of the metal wires and / or the conductive non-metallic wires can be the same or different. That is, in the same gas particulate matter purification device, the materials, number, wire diameter, etc. of the metal wires and / or the conductive non-metallic wires of the first discharge beam, the second discharge beam, and the third discharge beam can be completely the same, different, or not completely the same.

[0159] In one embodiment of the present invention, the first discharge beam, the second discharge beam, and the third discharge beam all satisfy one or two of the following conditions: (1) the discharge beam includes n metal wires and / or conductive non-metallic wires, wherein n is greater than or equal to 10,000; (2) the discharge beam includes multiple metal wires and / or conductive non-metallic wires, and the diameter of the metal wires ranges from 0.1 to 100 μm, or the diameter of the conductive non-metallic wires ranges from 0.1 to 100 μm; wherein, in the first purification device, one end of the multiple metal wires and / or conductive non-metallic wires of the first discharge beam is fixed together to form a fixed end, and the fixed end is arranged on the electrode rod, and the other end is a free end facing the first adsorption electrode; in the second purification device, one end of the multiple metal wires and / or conductive non-metallic wires of the third discharge beam is fixed together to form a fixed end, and the other end is a free end facing the second purification unit, and the multiple metal wires and / or non-metallic wires at the free end are in a dispersed state.

[0160] In one embodiment of the present invention, the discharge beam includes n metal wires and / or conductive non-metallic wires, wherein n is greater than or equal to 1,000; preferably, includes more than 5,000 metal wires and / or conductive non-metallic wires; preferably, includes more than 10,000 metal wires and / or conductive non-metallic wires; preferably, includes 10,000-200,000 metal wires and / or conductive non-metallic wires; preferably, includes 10,000-80,000 metal wires and / or conductive non-metallic wires. Typical but non-limiting numbers of metal wires and / or conductive non-metallic wires are 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 8,000, 10,000, 20,000, 50,000, 150,000, 200,000, 250,000, 300,000, 400,000, or 500,000.

[0161] Through this design, a discharge bundle composed of thousands of metal wires and / or conductive non-metallic wires, resembling a brush, utilizes corona discharge, with the tip of each free-end wire serving as a discharge point. This significantly improves the discharge effect and effectively reduces ozone generation to virtually zero. In the present invention, testing has shown that, under the same purification efficiency requirements, the voltage required to apply to the discharge bundle when combined with the same adsorption unit is far less than that required for a single electrode rod or wire, compared to a single electrode rod or wire combined with an adsorption unit for particulate matter purification. This offers the advantages of low energy consumption and low cost.

[0162] In one embodiment of the present invention, the diameter of the metal wire is in the range of 0.1-100 μm. Preferably, the diameter of the metal wire is in the range of 5-100 μm. Typical but non-limiting diameters of the metal wire are 0.1 μm, 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 10 μm, 12 μm, 15 μm, 20 μm, 3 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, or 100 μm. For example, the metal wire includes, but is not limited to, at least one of stainless steel fiber wire, titanium-chromium-aluminum alloy wire, titanium alloy wire, and nickel alloy wire. The metal wire includes stainless steel fiber wire, and the single fiber diameter of the stainless steel fiber wire can be in the range of 0.1-100 μm, or the single fiber diameter of the stainless steel fiber wire can be in the range of 5-100 μm. The carbon content of the discharge material is 90-99.9%, with a typical but non-limiting carbon content of 90%, 93%, 96%, or 99%.

[0163] In one embodiment of the present invention, the diameter range of the conductive non-metallic wire is 0.1-100um; preferably, the diameter range of the conductive non-metallic wire is 5-100um; typical but non-limiting diameters of the conductive non-metallic wire are: 0.1um, 0.5um, 1um, 2um, 3um, 4um, 5um, 10um, 12um, 15um, 20um, 3um, 40um, 50um, 60um, 70um, 80um, 90um, or 100um. For example, the conductive non-metallic wire includes but is not limited to carbon fiber wire, and the single fiber diameter of the carbon fiber wire can range from 0.1-100um; the single fiber diameter of the carbon fiber wire can range from 5-100μm, and typical but non-limiting single fiber diameters of the carbon fiber wire are: 0.1um, 0.5um, 1um, 2um, 3um, 4um, 5um, 10um, 12um, 15um, 20um, 3um, 40um, 50um, 60um, 70um, 80um, 90um or 100um.

[0164] In one embodiment of the present invention, referring to Figures 1 to 4 , a first purification device 10 is placed upright on the ground. A first airflow channel for airflow is formed between the first adsorption electrode and the first discharge electrode in the first purification device 10 . A second airflow channel is formed between the first electrode and the second electrode in the second purification device 20 . Both the first airflow channel and the second airflow channel are non-parallel to the ground. Specifically, both the first airflow channel and the second airflow channel are perpendicular to the ground.

[0165] With this design, when the first purification device 10 removes water droplets, dust, and viruses from the gas, the water droplets can flow downward due to gravity, for example, along the inner wall of the first adsorption electrode 11. Furthermore, if a small amount of water remains unpurified in the first purification device 10, the second purification unit 22 of the second purification device 20 can also absorb some of the water droplets, which will also flow downward due to gravity.

[0166] In one embodiment of the present invention, referring to FIG. 1 to FIG. 7 , the second electrode 2223 of the outer frame of the second purification device 20 extends toward the first purification device 10 to form the first adsorption electrode 11 of the first purification device 10 .

[0167] In one embodiment, when processing a large flow of gas, or when the gas in the application scenario is large in area, multiple gas particle purification units 100 can be spliced ​​together for use, and the splicing methods include series connection and / or parallel connection.

[0168] Example 2

[0169] One embodiment of the present invention provides a second purification unit. For other features and effects of the gas particulate matter purification device, please refer to Example 1. In addition, this embodiment only describes the differences from the second purification unit in Example 1, and the similarities are only mentioned and will not be repeated.

[0170] 1 to 5 , the second purification unit 22 includes a plurality of alternately arranged first electrodes 221 and second electrodes 222, the first electrode 221 including a first electrode first end 2211 and a first electrode second end 2212, the second electrode 222 including a second electrode first end 2221 and a second electrode second end 2222, a gas inlet being located between the first electrode first end 2211 and the second electrode first end 2221, a gas outlet being located between the first electrode second end 2212 and the second electrode second end 2222, and a first conductive fixing mechanism 30 for electrically connecting and fixing the plurality of first electrodes 221 being provided at the first electrode second end 2212.

[0171] With this design, the first conductive fixing mechanism 30 is positioned at the gas outlet of the second purification unit 22. The gas flowing through the first conductive fixing mechanism 30 is clean, preventing contamination. The gas inlet of the second purification unit 22, where dust is most likely to accumulate, lacks any connecting structure. This ensures that the electric field formed by the first electrode 221 and the second electrode 222 for adsorbing particulate matter is relatively stable and less susceptible to short circuits. When the airflow path of the second purification unit 22 is positioned perpendicular to the bottom surface, if water mist is adsorbed by the second purification unit 22, the water droplets can flow down under the action of gravity, leaving the area at the first conductive fixing mechanism 30 clean and less susceptible to short circuits.

[0172] In one embodiment of the present invention, referring to Figures 1 to 5, the first conductive fixing mechanism 30 includes a fixing bracket 31 and a bendable connector 32 arranged at the second end 2212 of the first electrode. The fixing bracket 31 is provided with a socket 33 that cooperates with the bendable connector 32. The bendable connector 32 is inserted into the socket 33 and then bent to fix the multiple first electrodes 221 on the fixing bracket 31.

[0173] Through such a design, a plurality of first electrodes 221 can be connected into one body, thereby achieving electrical connection.

[0174] In one embodiment of the present invention, referring to Figures 1 to 5 , the bendable connector 32 includes an insertion section 321 and a bending section 322 disposed on top of the insertion section 321. The fixed bracket 31 includes a top plate 311 disposed on top of the fixed bracket 31, and the top plate 311 has an insertion hole 33. After the bendable connector 32 is inserted into the insertion hole 33 of the fixed bracket 31, the insertion section 321 is disposed within the insertion hole 33, and the bending section 322 is disposed above the top plate 311 of the fixed bracket 31 and bends. The insertion section 321 and the bending section 322 can be integrally formed.

[0175] Specifically, referring to Figures 1 to 5 , the number of the insertion segments 321 and the bending segments 322 of the bendable connector 32 can be one, two, or even more. When the bendable connector 32 includes multiple groups of insertion segments 321 and bending segments 322, the bending directions can be the same or different. For example, in Figure 2 , the bendable connector 32 includes two groups of insertion segments 321 and bending segments 322, and the two bending segments 322 have different bending directions.

[0176] Specifically, referring to Figures 1 to 5, when the bent section 322 is not bent, the insertion section 321 and the bent section 322 are perpendicular to each other, forming a roughly L-shaped shape. The plane in which the insertion section 321 and the bent section 322 lie is the same as the plane in which the first electrode 221 lies. After the bent section 322 is bent, the plane in which at least a portion of the bent section 322 lies intersects (at a certain angle to each other) with the plane in which the first electrode 221 lies. The first electrode 221, the insertion section 321, and the bent section 322 can be an integrally formed structure.

[0177] Through such a design, a plurality of first electrodes 221 can be connected into one body, thereby achieving electrical connection.

[0178] In one embodiment of the present invention, referring to Figures 1 to 5 , the bendable connector 32 further includes a fixing segment 323. The first electrode second end 2212 is provided at one end of the fixing segment 323, and the insertion segment 321 of the bendable connector 32 is provided at the other end of the fixing segment 323. This allows the upper surface of the fixing segment 323 to contact the inner wall of the top plate 311 after the bendable connector 32 is inserted into the insertion hole 33 of the fixing bracket 31. The first electrode 221, the insertion segment 321, the bending segment 322, and the fixing segment 323 may be integrally formed.

[0179] Specifically, referring to FIG. 1 to FIG. 5 , a portion of the second end 2212 of the first electrode extends outward within the plane where the first electrode is located to form a fixed segment 323 , and an insertion segment 321 is provided outside the fixed segment 323 .

[0180] This design makes processing easier and the structure more stable.

[0181] In one embodiment of the present invention, referring to FIG. 6 , the first conductive fixing mechanism further includes a protrusion 36 . The first electrode second end 2212 ′ of the first electrode 221 ′ is provided with the protrusion 36 , and a bendable connector 32 ′ may be provided above the protrusion 36 .

[0182] Specifically, referring to Figure 6 , a portion of the second end 2212' of the first electrode extends outward within the plane of the first electrode to form a protrusion 36. A portion of the protrusion 36 also extends outward within the plane of the first electrode to form a fixed section 323'. The insertion section 321' is disposed above the fixed section 323'. The insertion section 321' is provided on one side of the fixed section 323', and the protrusion 36 is provided on the other side of the fixed section 323'. When the bending section 322' is not bent, the insertion section 321' and the bending section 322' are perpendicular to each other, forming a roughly L-shape. When the bending section 322' is not bent, the plane in which the insertion section 321', the bending section 322', the fixed section 323', and the protrusion 36 are located is the same as the plane in which the first electrode 221' is located.

[0183] With such a design, the protrusion 36 can be used in conjunction with the fixing bracket.

[0185] 1 to 5 , after the first electrodes 221 on both sides of the bendable connector 32 are inserted into the slots 34 of the side panels 312 , the bendable connector 32 is inserted into the jacks 33 of the fixing bracket 31 to complete the installation of the fixing bracket 31 and the first electrodes 221 .

[0186] More specifically, referring to Figures 1 to 5, after the first electrodes 221 on both sides of the fixing section 323 are inserted into the slots 34 of the side plate 312, it can be understood that the fixing section 323 moves along the inner wall of the side plate 312, so that the first electrodes 221 on both sides of the fixing section 323 are inserted into the slots 34 of the side plate 312. This then allows the flexible connector 32 to be inserted into the socket 33 of the fixing bracket 31, completing the installation of the fixing bracket 31 and the first electrodes 221.

[0187] In one embodiment of the present invention, referring to FIG. 1 to FIG. 6 , the protrusion 36 is inserted into the slot 34 of the side plate 312 .

[0188] Specifically, referring to Figures 1 to 6, after the protrusions 36 on both sides of the fixing section 323' are inserted into the slots 34 of the side plate 312, it can be understood that the fixing section 323' moves along the inner wall of the side plate 312, so that the protrusions 36 on both sides of the fixing section 323 are inserted into the slots 34 of the side plate 312. This then allows the bendable connector 32' to be inserted into the socket 33 of the fixing bracket 31, thereby completing the installation of the fixing bracket 31 and the first electrode 221.

[0189] In one embodiment of the present invention, referring to Figures 1 to 5, the bottom of the slot 34 has a preset distance from the top plate 311, and the height of the fixing section 323 is a preset distance, so that when the first electrode 221 on both sides of the fixing section 323 is inserted into the slot 34, the upper surface of the fixing section 323 contacts the inner wall of the top plate 311.

[0190] In one embodiment of the present invention, referring to Figures 1 to 6, the bottom of the slot 34 is at a preset distance from the top plate 311, and the height of the fixing section 323' is at a preset distance so that when the protrusion 36 on both sides of the fixing section 323' is inserted into the slot 34, the upper surface of the fixing section 323' contacts the inner wall of the top plate 311.

[0191] In one embodiment of the present invention, referring to Figures 1 to 5, the outermost side of the first electrode 221 is the outermost first electrode 2213. For the convenience of processing, the connection method between the outermost first electrode 2213 and the fixing bracket 31 can also be a screw connection, that is, screw connecting plates 35 are provided at both ends of the fixing bracket 31 along the length direction, and the outermost first electrode 2213 is connected to the screw connecting plate 35 of the fixing bracket 31.

[0192] In one embodiment of the present invention, referring to Figures 1 to 5, the middle portion of the side plate 312 between adjacent slots 34 of the fixing bracket 31 is arranged above the second electrode 222, so that the first electrode 221 in the slot is arranged between adjacent second electrodes 222.

[0193] Specifically, the fixing bracket 31 is made of a conductive material (such as stainless steel), the second electrode 222 is grounded, and the first electrode 221 is connected to a high voltage. Those skilled in the art will appreciate that a certain distance exists between the fixing bracket 31 and the second electrode 222 to prevent current breakdown. In other words, the middle portion of the side plate 312 between adjacent slots 34 of the fixing bracket 31 is positioned above the second electrode 222 and is spaced a certain distance from the second electrode.

[0194] Through such a design, a plurality of first electrodes and second electrodes are alternately arranged, and this assembly method makes the structure simple.

[0195] In one embodiment of the present invention, referring to Figures 1 to 5, the second electrode 222 includes two outer frame second electrodes 2223 arranged on the outermost side, a plurality of internal second electrodes 2224 arranged on the inner side, and an outer frame electrode connecting plate 2225 connecting the two sides of the outer frame second electrode 2223. The outer frame second electrode 2223 and the outer frame electrode connecting plate 2225 form a hollow tube with a rectangular cross-section, and the internal second electrode 2224 is a flat plate. The side of the internal second electrode 2224 and the outer frame electrode connecting plate 2225 are provided with a second conductive fixing mechanism 40. The second conductive fixing mechanism 40 fixes the plurality of internal second electrodes 2224 to the outer frame electrode connecting plate 2225, so that the internal second electrodes 2224 and the outer frame second electrode 2223 are arranged in parallel, so as to realize the alternating arrangement of the first electrode 221 and the outer frame second electrode 2223, or the internal second electrode 2224.

[0196] In one embodiment of the present invention, referring to Figures 1 to 5, the second conductive fixing mechanism 40 includes a bendable connector 41 disposed on the side of the inner second electrode 2224 and a socket 42 disposed on the side wall of the outer frame electrode connecting plate 2225. The socket 42 cooperates with the bendable connector 41. After the bendable connector 41 is inserted into the socket 42, it bends to fix the plurality of inner second electrodes 2224 to the outer frame electrode connecting plate 2225. The bendable connector 41 in this embodiment can refer to the bendable connector 32 disposed on the second end 2212 of the first electrode described above. The bendable connector 41 includes an insertion section 411 and a bending section 412 disposed at the top of the insertion section 411. After the bendable connector 41 is inserted into the socket 42, the insertion section 411 is disposed within the socket 42, and the bending section 412 is disposed on the outside of the side wall of the outer frame second electrode 2223 and bends.

[0197] Specifically, the insertion hole 42 may extend to the side wall edge of the outer frame electrode connecting plate 2225 , that is, as shown in the figure, the insertion hole 42 may not extend to the side wall edge of the outer frame electrode connecting plate 2225 .

[0198] In one embodiment of the present invention, referring to Figure 7, the second conductive fixing mechanism 40' includes a protrusion 43 provided on the side of the internal second electrode, and a socket 42' provided on the outer frame electrode connecting plate. The protrusion 43 is inserted into the socket 42' and snapped into the bottom of the socket 42' to fix the multiple internal second electrodes on the outer frame electrode connecting plate.

[0199] 7 , a portion of the side portion of the internal second electrode extends outward along the plane where the internal second electrode is located to form a protrusion 43 , and the internal second electrode is moved along the inner wall of the outer frame electrode connecting plate so that the protrusion 43 is inserted into the socket 42 'and snaps into the bottom of the socket 42 '.

[0200] Specifically, referring to FIG. 7 , two opposite sides of the inner second electrode are respectively provided with protrusions 43 .

[0201] In one embodiment of the present invention, referring to FIG. 1 to FIG. 5 , the outer frame second electrode 2223 and the outer frame electrode connecting plate 2225 may be an integrally formed structure, or may be a separate structure that is subsequently assembled together.

[0202] In one embodiment of the present invention, referring to FIG. 1 to FIG. 5 , the second purification unit further includes an insulating device 51 , which is provided between the fixing bracket 31 and the second electrode 2223 of the outer frame to ensure insulation between the first electrode 221 and the second electrode 222 .

[0204] In one embodiment of the present invention, referring to FIG. 1 to FIG. 5 , the outer frame second electrode 2223 of the second purification unit 22 extends toward the first purification unit 10 to form the first adsorption unit 11 of the first purification unit 10 .

[0205] Example 3

[0206] One embodiment of the present invention provides a second purification unit. For other features and effects of the gas particulate matter purification device, please refer to Example 1. In addition, this embodiment only describes the differences from the second purification unit in Example 1, and the similarities are only mentioned and will not be repeated.

[0207] 8 to 13, the second purification unit 60 includes a plurality of first electrodes 611 and a plurality of second electrodes 612, the second electrode 612 is grounded and forms an electric field for adsorption of particulate matter with the first electrode 611, the first electrode 611 and the second electrode 612 are both hollow tubes with different diameters, the first electrode 611 and the second electrode 612 are coaxially mounted and the first electrode 611 and the second electrode 612 are alternately arranged in sequence from the axis to the periphery, wherein the second adsorption unit 61 further includes an upper connecting bracket 613 and a lower connecting bracket 614, the upper connecting bracket 613 is arranged at one end 6111 of the first electrode 611 and electrically connects and fixes the plurality of first electrodes 611 together, and the lower connecting bracket 614 is fixed to the first electrode 611. The bracket 614 is arranged at one end 6112 of the second electrode 612 and electrically connects and fixes the multiple second electrodes 612 together. A first opening 6113 is formed between the other end 6112 of adjacent first electrodes 611, and a second opening is formed between the other end of adjacent second electrodes (not shown in the figure, and can be understood by referring to the first electrode 611). The multiple first electrodes 611 connected together are inserted from the second opening between the multiple second electrodes 612 connected together, and the multiple second electrodes 612 connected together are inserted from the first opening 6113 between the multiple first electrodes 611 connected together, so that the first electrodes 611 and the second electrodes 612 are arranged alternately in sequence.

[0208] With such a design, the structure is simple and it is not easy to cause a short circuit in the second purification unit.

[0209] In one embodiment of the present invention, referring to Figures 8 to 13, the second adsorption unit 61 also includes an insulating positioning connection mechanism 615, the upper end portion 6151 of the insulating positioning connection mechanism 615 is arranged in the innermost first electrode 6114 and is positioned and connected to the upper connecting bracket 613, and the lower end portion 6152 of the insulating positioning mechanism 615 is arranged in the innermost second electrode 6122 and is positioned and connected to the lower connecting bracket 614, so that when multiple first electrodes 611 and multiple second electrodes 612 are installed in a mutually inserted manner, the distance between the first electrode 611 and the second electrode 612 is the same.

[0210] Specifically, the insulating positioning connection mechanism 615 can be a columnar structure, an "I"-shaped structure, a frustum-shaped structure, etc.; the sizes of the upper end 6151 and the lower end 6152 of the insulating positioning connection mechanism 615 can be the same or different; when the upper end 6151 of the insulating positioning connection mechanism 615 is set on the innermost first electrode 6114, the side 61511 of the upper end 6151 can be adapted to the inner surface size of the innermost first electrode 6114, or it can not be adapted to the inner surface size of the innermost first electrode 6114; the side 61522 of the lower end 6152 can be adapted to the inner surface size of the innermost second electrode 6122, or it can not be adapted to the inner surface size of the innermost second electrode 6122.

[0211] Specifically, for example, the insulating positioning connection mechanism is an "I"-shaped structure, 615 including an upper end 6151, a lower end 6152, and a support member 6153 disposed between the upper end 6151 and the lower end 6152. This structure saves more materials than a cylindrical structure.

[0212] Specifically, for example, when the side portion 61511 of the upper end portion 6151 does not match the inner surface size of the innermost first electrode 6114, and the side portion of the lower end 6152 does not match the inner surface size of the innermost second electrode 6122, the upper end portion 6151 and the upper connecting bracket 613, or the lower end portion 6152 and the lower connecting bracket 614 can be used to position them. If the first electrode 611 and the second electrode 612 are cylindrical, the center of the upper connecting bracket 613 and the center of the lower connecting bracket 614 are concentric, and the center of the upper end portion 6151 is aligned with the center of the upper connecting bracket 613. The center of 613 is connected with screws, the center of the lower end 6152 is connected with the center of the lower connecting bracket 614 with screws, and the center of the upper end 6151 is aligned with the center of the lower end 6152. It is only necessary to ensure that the distance between the first electrodes 611 connected together is 2L, and the distance between the second electrodes 612 connected together is 2L. After being assembled together, the radius of the adjacent first electrodes 611 and the second electrodes differ by L. When connected by inserting each other, since the centers are aligned, the distance between the first electrode 611 and the second electrode 612 is L.

[0213] In one embodiment of the present invention, referring to Figures 8 to 13, the outer diameter of the side 61511 of the upper end portion 6151 is adapted to the inner surface size of the innermost first electrode 6114, and the outer diameter of the side 61521 of the lower end portion 6152 is adapted to the inner surface size of the innermost second electrode 6122, wherein the lower end portion 6152 is placed on the innermost second electrode 6122, and when inserted and installed, the innermost first electrode 6114 moves along the side 61511 of the upper end portion 6151 to position the distance between the first electrode 611 and the second electrode 612; or, the upper end portion 6151 is set on the innermost first electrode 6114, and when inserted and installed, the innermost second electrode 6122 moves along the side 61521 of the lower end portion 6152 to position the distance between the first electrode 611 and the second electrode 612.

[0214] Through such a design, the following effects can be achieved:

[0215] (1) Easy to install;

[0216] (2) The gas flows in from one end 6121 of the second electrode 612. When the side portion 61521 of the lower end 6152 of the insulating positioning connection mechanism 615 is adapted to the inner surface size of the innermost second electrode 6122, the gas will not enter the interior of the innermost second electrode 6122, that is, the flow channel entrance of the innermost second electrode 6122 is blocked by the lower end 6152, and the insulating positioning connection mechanism 615 will not be contaminated. For example, the upper end 6151 and the support member 6153 of the insulating positioning connection mechanism 615 will not be contaminated. The connection between the first electrode 611 and the second electrode 612 is insulated by the insulating positioning connection mechanism, so that the electric field of the second electrode 611 and the second electrode 612 can be stabilized and not easily short-circuited.

[0217] Specifically, referring to Figures 8 to 13 , the distance between the first electrode 611 and the second electrode 612 is L, the distance between the first electrodes 611 is 2L, the distance between the second electrodes 612 is 2L, and the size difference between the side portion 61511 of the upper end portion 6151 and the side portion 61521 of the lower end portion 6152 is 2L. For example, the first electrode 611 and the second electrode 612 are cylindrical, the upper end portion 6151 and the lower end portion 6152 are cylindrical, and the outer diameters (outer diameters) of the cylindrical upper end portion 6151 and the cylindrical lower end portion 6152 differ by 2L, that is, the outer radius differs by L.

[0218] In one embodiment of the present invention, referring to FIG. 8 to FIG. 13 , the upper end portion 6151 is disposed within an end portion 6111 of the innermost first electrode 6114 , and the lower end portion 6152 is disposed within an end portion 6121 of the innermost second electrode 6122 .

[0219] This design facilitates the connection between the upper end portion 6151 and the upper connecting bracket 613 , and the connection between the lower end portion 6152 and the lower connecting bracket 614 .

[0220] In one embodiment of the present invention, referring to Figures 8 to 13, there is a height difference H between the end 6121 of the second electrode 612 connected to the lower connecting bracket 614 and the end 6114 of the first electrode 611 provided with the first opening 6113, and there is a height difference between the end 6111 of the first electrode 611 connected to the upper connecting bracket 613 and the end of the second electrode 612 provided with the second opening.

[0221] Through such a design, since the upper connecting bracket 613 and the lower connecting bracket 614 are made of conductive materials, if there is no height difference H, a short circuit will occur. Those skilled in the art will understand that the height difference is greater than the height of the side plate 6134 of the connecting bracket 614. Since the connecting bracket 614 is made of conductive material, if the height difference is equal to the height of the side plate 6134 of the connecting bracket 614, then the first electrode 611 and the second electrode 612 will be short-circuited.

[0222] In one embodiment of the present invention, referring to Figures 8 to 13 , the height difference H is determined by the length of the insulating positioning connection mechanism 615. Since the first electrode 611 and the second electrode 612 are assembled in a plug-in manner at one end and connected to the insulating positioning connection mechanism 615 disposed therein at the other end, the length of the insulating positioning mechanism 615 determines the insertion depth of the first electrode 611 and the second electrode 612. The longer the insulating positioning mechanism 615, the shorter the insertion depth and the greater the height difference H.

[0223] In one embodiment of the present invention, referring to Figures 8 to 13 , the upper connecting bracket 613 includes a fixed plate 6131 and conductive mounting members 6132. Multiple conductive mounting members 6132 are radially arranged around the fixed plate 6131. ​​Side plates 6134 are provided on either side of the conductive mounting members 6132. Each side plate 6134 has multiple electrode mounting slots 6133 for securing the first electrode 611. The upper end 6151 is connected to the fixed plate 6131. ​​The lower connecting bracket 614 has a substantially identical structure to the upper connecting bracket 613. To accommodate the different sizes of the first and second electrodes, the lower connecting bracket 614 and the upper connecting bracket 613 are of different sizes. The lower connecting bracket 614 includes a fixed plate and a conductive mounting member, and multiple conductive mounting members are circumferentially arranged in a radial shape around the fixed plate; wherein, side plates 6134 are provided on both sides of the conductive mounting member, and the side plates 6134 are provided with multiple electrode mounting grooves for fixing the second electrode, and the lower end portion is connected to the fixed plate. For the convenience of processing, the outermost second electrode 6123 is connected to the lower connecting bracket 614 by screw connection or riveting.

[0224] In one embodiment of the present invention, referring to FIG10 , the conductive mounting member 6132 includes a main body plate 6135, the two sides of which are bent downward to form two side plates 6134. Electrode mounting slots 6133 are provided through the side plates 6134 and a portion of the main body plate 6135. When the first electrode or the second electrode is installed in the electrode mounting slot 6133, it is first inserted into the electrode mounting slot 6133 of the side plate 6134, and then inserted into the electrode mounting slot 6133 of the main body plate 6135, ultimately completing the installation of the first electrode or the second electrode in the electrode mounting slot 6133. Alternatively, the electrode mounting slot 6133 may be provided only through the side plate 6134, and when the first electrode or the second electrode is installed in the electrode mounting slot 6133, it is inserted into the electrode mounting slot 6133 of the side plate 6134, ultimately completing the installation of the first electrode or the second electrode in the electrode mounting slot 6133.

[0225] In one embodiment of the present invention, referring to Figures 8 to 13, the second purification unit 60 also includes an insulating top plate 62, one end of the outermost second electrode 6123 extends along the length direction to form an upper extension portion 6124, the peripheral side of the insulating top plate 62 is clamped into the upper extension portion 6124 of the outermost second electrode 6123, and the inner side of the insulating top plate 62 is connected to the upper connecting bracket 613.

[0226] With such a design, the first electrode 611 and the second electrode 612 can be fixed together again.

[0227] In one embodiment of the present invention, referring to FIG. 8 to FIG. 13 , the insulating top plate 62 is provided with air holes.

[0228] In one embodiment of the present invention, referring to FIG. 8 to FIG. 13 , the other end of the outermost second electrode 6123 extends along the length direction to form a lower extension portion 6125 , and the second discharge beam is disposed in the lower extension portion 6125 .

[0229] Example 4

[0230] One embodiment of the present invention provides a second purification unit. For other features and effects of the gas particulate matter purification device, please refer to Example 1. In addition, this embodiment only describes the differences from the second purification unit in Examples 1 and 3, and the similarities are not repeated.

[0231] 14 to 18 , the second purification unit 70 includes a first electrode 71 and a second electrode 72 , both of which are hollow tubes of different diameters. The first electrode 71 and the second electrode 72 are coaxially mounted and the first electrode 71 and the second electrode 72 are alternately arranged in sequence from the axis to the periphery. The second purification unit 70 further includes an upper connecting bracket 73 and a lower connecting bracket 74 . The upper connecting bracket 73 is arranged at one end of the first electrode 71 and electrically connects and fixes the plurality of first electrodes 71 together. The lower connecting bracket 74 is arranged at one end of the second electrode 72 and electrically connects and fixes the plurality of second electrodes 72 together. A first opening is formed between the other ends of adjacent first electrodes 71 , and a second opening is formed between the other ends of adjacent second electrodes 72 . The plurality of connected first electrodes 71 are inserted between the plurality of connected second electrodes 72 from the second opening, and the plurality of connected second electrodes 72 are inserted between the plurality of connected first electrodes 71 from the first opening, so that the first electrodes 71 and the second electrodes 72 are alternately arranged in sequence.

[0232] In one embodiment of the present invention, referring to FIG. 14 to FIG. 18 , the upper connecting bracket 73 fixes the plurality of first electrodes 71 together at equal intervals, and the lower connecting bracket 74 electrically connects and fixes the plurality of second electrodes 72 together at equal intervals.

[0233] In one embodiment of the present invention, referring to Figures 14 to 18, the second purification unit 70 further includes an insulating positioning bracket 75 disposed above the upper connecting bracket 73. The insulating positioning bracket 75 includes a positioning column 751 and a positioning member 752. The positioning column 751 is positioned with the upper connecting bracket 73. When the plurality of first electrodes 71 and the plurality of second electrodes 72 are installed in an inter-inserted manner, the positioning member 752 cooperates with the outermost second electrode 721 to maintain a certain distance between the first electrode 71 and the second electrode 72. When the second purification unit 70 includes a plurality of first electrodes 71 and a plurality of second electrodes 72, the insulating positioning bracket 75 can ensure that the distance between the first electrode 71 and the second electrode 72 is the same; when the second purification unit 70 includes one first electrode 71 and one second electrode 72, the insulating positioning bracket 75 can ensure that the distance between the first electrode 71 and the second electrode 72 is maintained. “The positioning column 751 is positioned with the upper connecting bracket 73” can be understood as the positioning column 751 can be directly connected to the first electrode 71, or the positioning column 751 can be indirectly connected to the first electrode 71. The solution of “the positioning column 751 is connected to the upper connecting bracket 73, and the upper connecting bracket 73 fixes the first electrode 71” in the following text is that the positioning column 751 is indirectly connected to the first electrode 71.

[0234] Through such a design, since all the first electrodes 71 are equidistant and concentric, and all the second electrodes 72 are equidistant and concentric, the positioning column 751 of the insulating positioning bracket 75 is connected to the upper connecting bracket 73, that is, the insulating positioning bracket 75 is positioned and connected to the first electrode 71. When the outermost second electrode 721 moves and is positioned along the positioning piece 752 of the insulating positioning bracket 75, it drives all the second electrodes 72 to move and be positioned along the positioning piece of the insulating positioning bracket 75, thereby making the first electrode 71 and the second electrode 72 equidistant and concentric.

[0235] In one embodiment of the present invention, referring to FIG. 14 to FIG. 18 , the positioning member 752 is a circular positioning member 752 having a stop groove 753 , and the outermost second electrode 721 is connected to the positioning member 752 by being snapped into the stop groove 753 .

[0236] Specifically, the circular locating member 752 includes an upper circular member 754 and a lower circular member 755 in the longitudinal direction. The outer diameter of the upper circular member 754 is larger than that of the lower circular member 755. Due to the difference in outer diameter, a stop groove 753 is formed at the connection between the upper circular member 754 and the lower circular member 755. When the multiple first electrodes 71 and the multiple second electrodes 72 are installed in an interlocking manner, the outermost second electrode 721 is inserted into the outer side of the lower circular member 755 and snaps into the stop groove 743, where it stops. "Snapping in" can be snapping in or not. When "snapping in" does not mean snapping in, it means that the outer second electrode 721 is snapped into the stop groove 743, preventing it from moving forward. The outermost second electrode 721 and the circular locating member 752 can be glued, screwed, or otherwise connected. The longitudinal direction refers to the length of the hollow tubular first or second electrode.

[0237] Through such a design, when the outermost second electrode 721 moves along the lower circular ring member 755 and stops at the stop groove 753, it drives all the second electrodes 72 to move along the lower circular ring member 755 and stop at the stop groove 753, thereby making the first electrode 71 and the second electrode 72 equidistant and concentric.

[0238] In one embodiment of the present invention, referring to Figures 14 to 18, the insulating positioning bracket 75 also includes a connecting frame 756, the positioning member 752 is a circular positioning member 752, the connecting frame 756 is arranged inside the circular positioning member 752, and the positioning column 751 is arranged below the connecting frame 756.

[0239] In one embodiment of the present invention, referring to Figures 14 to 18, the connecting frame 756 includes a central frame 7561 and a plurality of connecting rods 7562 arranged around the central frame 7561, and the two ends of the connecting rod 7562 are respectively connected to the circular positioning member 752 and the central frame 7561, and a positioning column 751 is provided under each connecting rod 7562.

[0240] In one embodiment of the present invention, referring to Figures 14 to 18, the insulating positioning bracket 75 includes a metal bracket 757, which is arranged between the positioning column 751 and the connecting frame 756 and the positioning member 752, and the metal bracket 757 is arranged directly below the connecting frame 756 and the positioning member 752, and the positioning column 751 is made of ceramic material.

[0241] This design makes positioning post 751 flame-retardant when it is made of ceramic material and metal bracket 757 is positioned above it. Industrial electric fields have previously experienced fires. For example, in environments with high moisture content, severe arcing between the two electrodes can spark, causing the plastic connecting the two electrodes to burn. Connecting bracket 756 and positioning member 752 are typically made of insulating plastic. By replacing the connecting member with ceramic material and adding a metal bracket, even if the two electrodes spark, it won't necessarily cause the insulating plastic to burn.

[0242] Specifically, referring to Figures 14 to 18, the metal bracket 757 includes an outer ring 7571, a central fixing member 7572, and multiple connecting rods 7573 connecting the outer ring 7571 and the central fixing member 7572. The central fixing member 7572 is located in the center of the metal bracket 757, and the multiple connecting rods 7573 are arranged around the central fixing member 7572. The outer ring 7571 is located directly below the ring positioning member 752, the central fixing member 7572 is located directly below the central frame 7561 of the connecting frame 756, and the connecting rods 7573 of the metal bracket 757 are located directly below the connecting rods 7562 of the connecting frame 756.

[0243] In one embodiment of the present invention, referring to Figures 14 to 18, the upper connecting bracket 73 includes a conductive mounting member 731, which includes a main plate 7311. The two sides of the main plate 7311 are bent upward or downward to form two side plates 7312. The side plates 7312 are provided with multiple electrode mounting grooves 732 for fixing the first electrode 71 or the second electrode 72, or the side plates 7312 and the main plate 7311 are provided with multiple electrode mounting grooves 732 for fixing the first electrode 71 or the second electrode 72. Similarly, the lower connecting bracket 74 has the same structure as the upper connecting bracket 73 and also has the structure of the upper connecting bracket 73 described above.

[0244] In one embodiment of the present invention, referring to Figures 14 to 18, the upper connecting bracket 73 also includes a fixing plate 732, and a plurality of conductive mounting members 731 are radially arranged around the fixing plate 732. Similarly, the lower connecting bracket 74 also has the fixing plate structure of the upper connecting bracket 73. Since the diameters of the innermost first electrode and the innermost second electrode are different, the sizes of the fixing plates of the upper connecting bracket 73 and the lower connecting bracket 74 can be different. In addition, the shape of the fixing plate 732 can be a solid circle or an annular shape. A battery cell can be provided in the innermost electrode. The annular fixing plate can be mounted on the outside of the battery cell for fixed installation, and the solid circular fixing plate can be arranged on the upper or lower part of the battery cell for fixed installation.

[0245] Specifically, the number of the conductive mounting members 731 can be determined according to actual needs, and can be two, three, five, six, ten, etc.

[0246] In one embodiment of the present invention, referring to Figures 14 to 18, the two sides of the main plate 7311 are bent upward to form two side plates 7312, and the electrode mounting groove 732 is set through the main plate 7311 and part of the side plate 7312. When the first electrode 71 is installed in the electrode mounting groove 732, it is first inserted into the electrode mounting groove 732 of the main plate 7311, and then inserted into the electrode mounting groove 732 of the side plate 7312, and finally the first electrode 71 is installed in the electrode mounting groove 732.

[0247] In one embodiment of the present invention, referring to Figures 14 to 18, the outer end of the conductive mounting member 731 is connected to the outermost first electrode or the outermost second electrode, the outermost electrode is the outermost second electrode 721, and the outer end of the conductive mounting member of the lower connecting bracket 74 is connected to the outermost second electrode 721, which can be riveted.

[0248] In one embodiment of the present invention, referring to Figures 14 to 18, when multiple first electrodes 71 and multiple second electrodes 72 are installed in a mutually inserted manner, there is a certain distance between the end of the first electrode 71 and the lower connecting bracket 74, and there is a certain distance between the end of the second electrode 72 and the upper connecting bracket 73.

[0249] With such a design, since the upper connecting bracket 73 and the lower connecting bracket 74 are made of conductive materials, insulation between the first electrode 71 and the second electrode 72 can be ensured. If there is no distance, a short circuit will occur.
