Description

Technical Field

[0001] This utility model relates to the field of gas purification, specifically to an insulating positioning bracket. Background Technology

[0002] As people's environmental awareness increases, their understanding of and demand for purification of air pollutants (including but not limited to smoke, dust, VOCs, and engine exhaust) are also constantly rising. Therefore, more and better purification technologies are gradually being installed and used in vehicles, factories, and homes. Among these purification technologies, electrostatic precipitator technology has a very widespread application. The principle of electrostatic precipitator technology is that gas is ionized when it passes through an electrostatic field. Particulate matter in the gas combines with charged ions and tends to move towards the electrode with the opposite polarity of the charged ions, thus depositing. It is evident that the particulate matter removal rate is related to the charge efficiency of the particulate matter. However, existing technologies still suffer from the problem of complex structures in gas particulate matter purification devices, resulting in high manufacturing costs and unsatisfactory particulate matter removal rates and purification effects.

[0097] The beneficial effects of this utility model are as follows:

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

[0099] 2. The first purification device provided by this utility model is used to remove particulate matter from gas. The particulate matter includes, but is not limited to, pollutants such as water droplets, viruses, bacteria, dust, and radiation-containing aerosols. It has the characteristic of high temperature resistance and can be applied to environments such as automobile exhaust treatment and power plant exhaust gas purification.

[0100] 3. The first discharge electrode of the first purification device provided by this utility model includes multiple sets of circumferentially arranged discharge beam assemblies, and the discharge beam in the discharge beam assembly includes thousands of metal wires and / or conductive non-metal wires. The discharge beam is fixed on the discharge rod, similar to a brush. The discharge beam adopts corona discharge. The tip of each fiber 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 production.

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

[0102] Under the same purification efficiency requirements, compared with the purification device composed of an electrode rod or electrode wire and an adsorption electrode to purify particulate matter in the gas, when the first discharge electrode of this invention is combined with the same adsorption electrode, the voltage required to be applied by this invention is much less than the voltage required by an electrode rod or electrode wire. This has the advantages of low energy consumption and low cost, thus effectively reducing ozone production to almost none.

[0103] Compared to setting one or more discharge beams at a single location, the first discharge electrode provided by this invention has at least one set of discharge beam assemblies on an electrode rod. This extends the discharge length in the longitudinal direction, rapidly improving the dust removal efficiency of the purification device. Each set of discharge beam assemblies at the same location includes multiple circumferentially distributed discharge beams. This circumferential distribution around the electrode rod ensures higher discharge density and more uniform discharge in the lateral direction. This extension of the discharge electrode in both the longitudinal and lateral directions causes more particulate matter in the gas within the hollow adsorption electrode to become charged, improving the charging effect and thus enhancing the particulate matter adsorption effect, significantly increasing the gas purification rate. Furthermore, this discharge electrode structure design also effectively expands the adsorption electrode area of ​​the purification device, significantly improving its adsorption and purification capacity.

[0104] In the first discharge electrode provided by this utility model, in one case, a discharge beam is also provided at one or both ends of the electrode rod. After applying voltage, the discharge beam at the end generates positive or negative ions through corona discharge. The discharge beam is in the same direction as the gas flow. When the gas flows through the first discharge electrode, the charging efficiency of particulate matter in the gas can be further improved, thereby improving the gas purification efficiency.

[0105] 5. The first type of second purification unit, when equipped with a first conductive fixing mechanism, has the following advantages:

[0106] The first conductive fixing mechanism is located at the gas outlet of the second purification unit. The gas flowing through the first conductive fixing mechanism is clean gas, and the first conductive fixing mechanism will not be contaminated. The gas inlet of the second purification unit is most prone to dust accumulation. There are no connecting structures at this point, making the electric field formed by the first electrode and the second electrode for particulate matter adsorption relatively stable and less prone to short circuits. When the airflow channel of the second purification unit is set perpendicular to the bottom surface, if the second purification unit adsorbs water mist, the water droplets can flow down under the action of gravity, leaving the first conductive fixing mechanism in a clean state and less prone to short circuits.

[0107] 6. Both the second and second purification units adopt an interlocking structure design, which simplifies the structure of the second purification unit and reduces the risk of short circuits. Furthermore, the interlocking structure includes an insulating positioning bracket or an insulating positioning connection mechanism, ensuring that when multiple first electrodes and multiple second electrodes are installed in an interlocking manner, the distance between the first electrodes and the second electrodes remains the same.

[0132] Example 1

[0133] One embodiment of this utility model provides a gas particulate matter purification device, see reference. Figure 1 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 to adsorb particulate matter. A first electric field is formed between the first adsorption electrode 11 and the first discharge electrode 12. The first adsorption electrode 11 is a hollow tube, and the first discharge electrode 12 penetrates into 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 a plurality of first discharge beams 122 circumferentially arranged on the electrode rod 121. In one embodiment, the discharge beam assembly 123 includes 1-6 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 this utility model, the first adsorption electrode 11 is a hollow tube, and the cross-section of the hollow tube is polygonal or circular.

[0135] In this 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 being energized by the applied voltage, so that the gas is ionized, the particulate matter in the gas becomes charged, and the charged particulate matter is adsorbed by the first adsorption electrode, thereby playing the role of purifying particulate matter.

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

[0137] With this design, the gas particulate matter purification device 1 can be applied to industrial chimneys for gas particulate matter purification. The gas particulate matter purification device 1 can effectively remove particulate matter such as water droplets, dust, and viruses from the flue gas. The gas enters the first purification device 10 and the second purification device 20 in sequence for purification. The first purification device 10 can mainly remove particulate matter such as water droplets, while the second purification device 20 can effectively remove particulate matter such as dust and viruses from the gas. At the same time, because the first purification device 10 effectively removes water from the gas, the working efficiency of the second purification device 20 is improved.

[0138] In one embodiment of this utility model, reference is made to Figure 1 The second purification device 20 also includes a third discharge beam 21, positioned in front of the second purification unit 22 along the airflow direction. The third discharge beam 21 comprises multiple metal wires and / or conductive non-metal wires, with the metal or conductive non-metal wires of the third discharge beam 21 facing the second purification unit 22. A certain distance exists between the tips of the metal or conductive non-metal wires of the third discharge beam 21 and the second purification unit 22. Thus, the second purification device 20 includes a second discharge beam 21 and a second purification unit 22 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 particulate matter 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 the particulate matter in the gas. The charged particulate matter enters the second purification unit 22 for particulate matter adsorption, significantly improving the particulate matter adsorption efficiency.

[0139] In this invention, the second purification unit includes multiple first electrodes and multiple second electrodes electrically connected together. The first and second electrodes are alternately arranged to form a second electric field for particulate matter adsorption. The first and second electrodes can be electrically connected to the two poles of a power supply, with one pole grounded. The first and second electrodes form the second electric field for particulate matter adsorption; that is, the first electrode is connected to the positive pole of the power supply and the second electrode to the negative pole, or vice versa. In this invention, there are two scenarios: first, the first electrode acts as a discharge electrode, discharging to charge the particulate matter, and the second electrode acts as an adsorption electrode, adsorbing the charged particulate matter; second, the second electrode acts as a discharge electrode, discharging to charge the particulate matter, and the first electrode acts as an adsorption electrode, adsorbing the charged particulate matter. In the second purification unit, gas enters the gas flow channel between two electrodes. The discharge electrode discharges to ionize the gas, and the particulate matter becomes charged. If the discharge electrode is connected to the negative terminal of the power supply and the adsorption electrode is connected to the positive terminal of the power supply (the adsorption electrode can be grounded), the particulate matter becomes negatively charged during this process. The negatively charged particulate matter is adsorbed onto the adsorption electrode. The particulate matter includes, but is not limited to, water droplets, viruses, bacteria, and radiation-containing aerosols. After being treated by the second electric field, the pollutants in the gas are removed, resulting in sterile, radiation-free, and virus-free clean gas, thus achieving the effect of gas purification.

[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 in Embodiment 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 are alternately arranged from the center to the outer 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 be referred to in Embodiment 3 or Embodiment 4.

[0142] In one embodiment of this utility model, when the first electrode and the second electrode of the second purification unit are both hollow tubes with different diameters, multiple first electrodes and multiple second electrodes are coaxially mounted and arranged alternately from the axis to the outer periphery. A power supply and / or rechargeable battery are disposed inside 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 are disposed inside the cylinder of the inner adsorption electrode or the inner induction electrode.

[0143] In one embodiment of this utility model, the gas particulate matter purification device further includes a fan, which is located on the side near the air outlet of the second purification unit. That is, along the airflow direction, the fan is located behind the second purification device, and the gas flows through the second purification unit of the second purification device before being discharged by 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 arranged along the central axis of the first adsorption unit 11.

[0145] In one embodiment of this utility model, such as Figure 1 As shown, in the first discharge electrode 12 of the first purification device 10, multiple first discharge beams in the same discharge beam assembly are uniformly arranged around the same circumference of the electrode rod.

[0146] In one embodiment of this utility model, the discharge beam assembly includes 1-15 first discharge beams. Preferably, it includes 1-3, or 3-7, or 8-15. Typical but non-limiting numbers of 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 this utility model, 3-21 discharge beam assemblies are arranged per meter on the electrode rod. Preferably, 3-7 discharge beam assemblies, 3-16 discharge beam assemblies, 3-18 discharge beam assemblies, or 16-21 discharge beam assemblies are arranged per meter on the electrode rod. Typical, but not limiting, numbers of discharge beam assemblies 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 distance between adjacent discharge beam assemblies can 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 discharge beam assemblies, and the number of first discharge beams in the discharge beam assembly can be set according to actual needs.

[0149] In one embodiment of this utility model, the first discharge beam in the discharge beam assembly is arranged at a certain angle to the axis of the electrode rod. Preferably, as follows... Figure 1 As shown, the first discharge beam 122 is set at 90° to the axis of the electrode rod 121.

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

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

[0152] In one embodiment of this utility model, such as Figure 1 As shown, the electrode rod 121 is provided with a second discharge beam at the end near 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 this utility model, such as Figure 2 As shown, a second discharge beam 21' is provided at the end of the electrode rod 121 near the gas inlet. With this design, a discharge beam is set at the end of the electrode rod of the discharge electrode near the gas inlet. After applying voltage, the discharge beam at the end generates positive or negative ions through corona discharge. The discharge beam is in the same direction as the gas flow. When the gas flows through the discharge electrode, the charging efficiency of particulate matter in the gas is further improved, thereby improving the gas purification efficiency.

[0154] In this invention, the first discharge beam comprises multiple metal wires and / or conductive non-metal wires (discharge materials). One end of each metal wire and / or non-metal wire is fixed together to form a fixed end, and the other end is a free end. The multiple metal wires and / or non-metal wires at the free end are dispersed. 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 all the first discharge beams and the inner wall of the first adsorption electrode is the same.

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

[0156] In this invention, multiple first discharge beams are fixed on an electrode rod. This design serves two purposes: first, it fixes one or more discharge beams; second, when the electrode rod is electrically connected to one pole of the power supply, the discharge beams are also connected to the power supply. In the case of multiple discharge beams, multiple discharge beams can be connected to one power supply simultaneously. The structure is simple and convenient.

[0157] In this invention, at least one set of discharge beam assemblies is provided on an electrode rod, which extends the discharge length in the longitudinal direction and rapidly improves the dust removal efficiency of the purification device. Each set of discharge beam assemblies includes multiple discharge beams distributed circumferentially. This circumferential distribution around the electrode rod ensures higher discharge density and more uniform discharge in the transverse direction. This extension of the discharge electrode in both the longitudinal and transverse directions causes more particulate matter in the gas within the hollow adsorption electrode to become charged, improving the charging effect and thus enhancing the adsorption effect of particulate matter, significantly improving the gas purification rate. Furthermore, this discharge electrode structure design also effectively expands the adsorption electrode area of ​​the purification device, significantly improving its adsorption and purification capacity.

[0158] In this invention, the structure of the first discharge beam, the second discharge beam, and the third discharge beam, and the materials of the metal wires and / or conductive non-metal wires can be the same or different. That is to say, in the same gas particulate matter purification device, the materials, number, and wire diameter of the metal wires and / or conductive non-metal wires of the first discharge beam, the second discharge beam, and the third discharge beam can be exactly the same or different.

[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-metal wires, wherein n is greater than or equal to 0.1 million; (2) the discharge beam includes multiple metal wires and / or conductive non-metal wires, the diameter of the metal wires is in the range of 0.1-100 μm, or the diameter of the conductive non-metal wires is in the range of 0.1-100 μm; wherein, in the first purification device, one end of the multiple metal wires and / or conductive non-metal wires of the first discharge beam is fixed together to form a fixed end, the fixed end is disposed 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-metal wires of the third discharge beam is fixed together to form a fixed end, the other end is a free end facing the second purification unit, and the multiple metal wires and / or non-metal wires at the free end are in a dispersed state.

[0160] In one embodiment of this utility model, the discharge beam comprises n metal wires and / or conductive non-metal wires, wherein n is greater than or equal to 1,000; preferably, it comprises more than 5,000 metal wires and / or conductive non-metal wires; preferably, it comprises more than 10,000 metal wires and / or conductive non-metal wires; preferably, it comprises 10,000 to 200,000 metal wires and / or conductive non-metal wires; preferably, it comprises 10,000 to 80,000 metal wires and / or conductive non-metal wires. Typical but non-limiting quantities of metal wires and / or conductive non-metal 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-metal wires, resembling a brush, is generated. The discharge bundle employs corona discharge, with the tip of each wire at its free end serving as a discharge point, significantly improving the discharge effect and effectively reducing ozone production to almost zero. In this invention, testing has shown that, under the same purification efficiency requirements, compared to purifying particulate matter in a gas using a single electrode rod or wire and an adsorption unit, the voltage required for the discharge bundle in this invention, when combined with the same adsorption unit, is far less than that required for a single electrode rod or wire. This results in advantages such as low energy consumption and low cost.

[0162] In one embodiment of this utility model, the diameter of the metal wire ranges from 0.1 to 100 μm; preferably, the diameter of the metal wire ranges from 5 to 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, the single fiber diameter of the stainless steel fiber wire can range from 0.1 to 100 μm, the single fiber diameter range of the stainless steel fiber wire can be 5-100 μm, and the carbon content in the discharge material is 90-99.9%, typically but non-limiting carbon content is 90%, 93%, 96%, or 99%.

[0163] In one embodiment of this utility model, the diameter of the conductive non-metallic wire ranges from 0.1 to 100 μm; preferably, the diameter of the conductive non-metallic wire ranges from 5 to 100 μm; typical but non-limiting diameters of the conductive non-metallic 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, conductive non-metallic wires include, but are not limited to, carbon fiber wires. The single fiber diameter of carbon fiber wires can range from 0.1 to 100 μm; the single fiber diameter of carbon fiber wires can range from 5 to 100 μm. Typical but non-limiting single fiber diameters of carbon fiber wires 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.

[0164] In one embodiment of this utility model, reference is made to Figures 1 to 4 The first purification device 10 is placed upright on the ground. A first airflow channel is formed between the first adsorption electrode and the first discharge electrode in the first purification device 10 to allow airflow to pass through. A second airflow channel is formed between the first electrode and the second electrode in the second purification device 20. Neither the first airflow channel nor the second airflow channel is 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 down due to gravity, for example, they can flow down along the inner wall of the first adsorption electrode 11. In addition, if a small amount of moisture remains in the first purification device 10, the second purification unit 22 of the second purification device 20 can also adsorb some water droplets, which will also flow down due to gravity.

[0166] In one embodiment of this utility model, reference is made to Figures 1 to 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 large flow rates of gas, or when the application scenario involves a large gas area, multiple gas particle purification units 100 can be connected together for use, and the connection method includes series and / or parallel connection.

[0168] Example 2

[0169] One embodiment of this utility model provides a second purification unit. For other features and effects of the gas particulate matter purification device, please refer to Embodiment 1. In addition, this embodiment only describes the differences from the second purification unit in Embodiment 1, and the same features will not be described again.

[0170] Reference Figures 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 includes a first electrode first end 2211 and a first electrode second end 2212. The second electrode 222 includes a second electrode first end 2221 and a second electrode second end 2222. The gas inlet is between the first electrode first end 2211 and the second electrode first end 2221, and the gas outlet is between the first electrode second end 2212 and the second electrode second end 2222. A first conductive fixing mechanism 30 is provided at the second electrode second end 2212 to electrically connect and fix the plurality of first electrodes 221.

[0171] With this design, the first conductive fixing mechanism 30 is located at the gas outlet of the second purification unit 22. The gas flowing through the first conductive fixing mechanism 30 is clean gas, and the first conductive fixing mechanism 30 will not be contaminated. The gas inlet of the second purification unit 22 is most prone to dust accumulation, and there is no connecting structure at this point, making the electric field formed by the first electrode 221 and the second electrode 222 for particulate matter adsorption relatively stable and less prone to short circuits. When the airflow channel of the second purification unit 22 is set perpendicular to the bottom surface, if the second purification unit 22 adsorbs water mist, the water droplets can flow down under the action of gravity, and the first conductive fixing mechanism 30 remains clean and less prone to short circuits.

[0172] In one embodiment of this utility model, reference is made to Figures 1 to 5 The first conductive fixing mechanism 30 includes a fixing bracket 31 and a bendable connector 32 disposed at the second end 2212 of the first electrode. The fixing bracket 31 is provided with an insertion hole 33 that mates with the bendable connector 32. After the bendable connector 32 is inserted into the insertion hole 33, it bends to fix the multiple first electrodes 221 on the fixing bracket 31.

[0173] With this design, multiple first electrodes 221 can be connected into one unit to achieve electrical connection.

[0174] In one embodiment of this utility model, reference is made to Figures 1 to 5The 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 in the insertion hole 33, and the bending section 322 is disposed above the top plate 311 of the fixed bracket 31 and is bent. The insertion section 321 and the bending section 322 can be integrally formed.

[0175] Specifically, refer to Figures 1 to 5 The number of insertion segments 321 and bending segments 322 in the bendable connector 32 can be one, two, or even more sets. When the bendable connector 32 includes multiple sets of insertion segments 321 and bending segments 322, the bending directions can be the same or different, for example... Figure 2 In the middle, the bendable connector 32 includes two sets of insertion sections 321 and bending sections 322, and the bending directions of the two bending sections 322 are different.

[0176] Specifically, refer 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, roughly L-shaped, and the plane containing the insertion section 321 and the bent section 322 is the same as the plane containing the first electrode 221. After the bent section 322 is bent, at least a portion of the plane containing the bent section 322 intersects the plane containing the first electrode 221 (at a certain angle). The first electrode 221, the insertion section 321, and the bent section 322 can be an integrally formed structure.

[0177] With this design, multiple first electrodes 221 can be connected into one unit to achieve electrical connection.

[0178] In one embodiment of this utility model, reference is made to Figures 1 to 5 The bendable connector 32 also includes a fixing section 323. One end of the fixing section 323 is provided with a second end 2212 of the first electrode, and the other end of the fixing section 323 is provided with an insertion section 321 of the bendable connector 32, so that after the bendable connector 32 is inserted into the insertion hole 33 of the fixing bracket 31, the upper surface of the fixing section 323 contacts the inner wall of the top plate 311. The first electrode 221, the insertion section 321, the bending section 322, and the fixing section 323 can be an integrally formed structure.

[0179] Specifically, refer to Figures 1 to 5 A portion of the second end 2212 of the first electrode extends outward in the plane of the first electrode to form a fixed segment 323, and an insertion segment 321 is provided on the outside of the fixed segment 323.

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

[0181] In one embodiment of this utility model, reference is made to Figure 6 The first conductive fixing mechanism also includes a protrusion 36. The second end 2212' of the first electrode of the first electrode 221' is provided with a protrusion 36, and a bendable connector 32' may be provided above the protrusion 36.

[0182] Specifically, refer 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 extends outward within the plane of the first electrode to form a fixed segment 323'. An insertion segment 321' is positioned above the fixed segment 323'. The insertion segment 321' is located on one side of the fixed segment 323', and the protrusion 36 is located on the other side of the fixed segment 323'. When the bent segment 322' is not bent, the insertion segment 321' and the bent segment 322' are perpendicular to each other, forming an approximate L-shape. When the bent segment 322' is not bent, the plane containing the insertion segment 321', the bent segment 322', the fixed segment 323', and the protrusion 36 is the same as the plane containing the first electrode 221'.

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

[0184] In one embodiment of this utility model, reference is made to Figures 1 to 5 The fixed bracket 31 includes side plates 312 disposed on both sides of the fixed bracket 31. The side plates 312 are provided with slots 34 and the first electrode 221 is inserted into the slots 34.

[0185] Specifically, refer to Figures 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 plate 312, the bendable connector 32 is inserted into the insertion holes 33 of the fixed bracket 31 to complete the installation of the fixed bracket 31 and the first electrodes 221.

[0186] More specifically, refer to Figures 1 to 5 After the first electrodes 221 on both sides of the fixing segment 323 are inserted into the slots 34 of the side plate 312, it can be understood that the fixing segment 323 moves along the inner wall of the side plate 312, so that the first electrodes 221 on both sides of the fixing segment 323 are inserted into the slots 34 of the side plate 312. This allows the bendable connector 32 to be inserted into the insertion hole 33 of the fixing bracket 31, thus completing the installation of the fixing bracket 31 and the first electrodes 221.

[0187] In one embodiment of this utility model, reference is made to Figures 1 to 6 The protrusion 36 is inserted into the slot 34 of the side plate 312.

[0188] Specifically, refer to Figures 1 to 6After the protrusions 36 on both sides of the fixing segment 323' are inserted into the slots 34 of the side plate 312, it can be understood that the fixing segment 323' moves along the inner wall of the side plate 312, so that the protrusions 36 on both sides of the fixing segment 323' are inserted into the slots 34 of the side plate 312. This allows the bendable connector 32' to be inserted into the insertion hole 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 this utility model, reference is made to Figures 1 to 5 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 first electrode 221 is inserted into the slot 34 on both sides of the fixing section 323, the upper surface of the fixing section 323 contacts the inner wall of the top plate 311.

[0190] In one embodiment of this utility model, reference is made 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 this utility model, reference is made to Figures 1 to 5 The outermost part of the first electrode 221 is the outermost first electrode 2213. For ease of processing, the outermost first electrode 2213 can also be connected to the fixed bracket 31 by screws. That is, the fixed bracket 31 has screw connecting plates 35 at both ends along the length direction, and the outermost first electrode 2213 is connected to the screw connecting plates 35 of the fixed bracket 31.

[0192] In one embodiment of this utility model, reference is made to Figures 1 to 5 The middle part of the side plate 312 between adjacent slots 34 of the fixing bracket 31 is disposed above the second electrode 222, so that the first electrode 221 in the slot is disposed between adjacent second electrodes 222.

[0193] Specifically, the fixing bracket 31 is made of conductive material (such as stainless steel), the second electrode 222 is grounded and the first electrode 221 is connected to high voltage. As those skilled in the art will understand, there is a certain distance between the fixing bracket 31 and the second electrode 222 to prevent current breakdown. That is to say, the middle part of the side plate 312 between adjacent slots 34 of the fixing bracket 31 is located above the second electrode 222 and at a certain distance from the second electrode.

[0194] This design allows for the alternating placement of multiple first and second electrodes, resulting in a simple assembly structure.

[0195] In one embodiment of this utility model, reference is made to Figures 1 to 5 The second electrode 222 includes two outer frame second electrodes 2223 disposed on the outermost side, a plurality of inner second electrodes 2224 disposed on the inner side, and an outer frame electrode connecting plate 2225 connecting the two sides of the outer frame second electrodes 2223. The outer frame second electrodes 2223 and the outer frame electrode connecting plate 2225 form a hollow tube with a rectangular cross-section. The inner second electrodes 2224 are flat plates. The sides of the inner second electrodes 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 inner second electrodes 2224 to the outer frame electrode connecting plate 2225, so that the inner second electrodes 2224 and the outer frame second electrodes 2223 are arranged in parallel, so as to realize that the first electrode 221 is alternately arranged with the outer frame second electrode 2223 or the inner second electrode 2224.

[0196] In one embodiment of this utility model, reference is made 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 an insertion hole 42 disposed on the side wall of the outer frame electrode connecting plate 2225. The insertion hole 42 cooperates with the bendable connector 41. After the bendable connector 41 is inserted into the insertion hole 42, it bends to fix the multiple inner second electrodes 2224 on 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 mentioned above. The bendable connector 41 includes an insertion section 411 and a bending section 412 disposed on the top of the insertion section 411. After the bendable connector 41 is inserted into the insertion hole 42, the insertion section 411 is disposed in the insertion hole 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 socket 42 may extend to the side wall edge of the outer frame electrode connection plate 2225, as shown in the figure, or the socket 42 may not extend to the side wall edge of the outer frame electrode connection plate 2225.

[0198] In one embodiment of this utility model, reference is made to Figure 7 The second conductive fixing mechanism 40' includes a protrusion 43 disposed on the side of the inner second electrode and an insertion hole 42' disposed on the outer frame electrode connecting plate. The protrusion 43 is inserted into the insertion hole 42' and snapped into the bottom of the insertion hole 42' to fix the multiple inner second electrodes to the outer frame electrode connecting plate.

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

[0200] Specifically, refer to Figure 7 The two opposite sides of the internal second electrode are respectively provided with protrusions 43.

[0201] In one embodiment of this utility model, reference is made to Figures 1 to 5 The outer frame second electrode 2223 and the outer frame electrode connecting plate 2225 can be an integrally formed structure or a separate structure that is assembled together later.

[0202] In one embodiment of this utility model, reference is made to Figures 1 to 5 The second purification unit also includes an insulation device 51. An insulation device 51 is provided between the fixed bracket 31 and the outer frame second electrode 2223 to ensure insulation between the first electrode 221 and the second electrode 222.

[0203] Specifically, the second purification unit also includes a connector 52, with the two ends of the connector 52 connected to the second electrode 2223 of the outer frame and the insulating component 51, respectively. The two ends of the insulating component are connected to the top plate 311 of the fixed bracket 31 and the connector 52, respectively.

[0204] In one embodiment of this utility model, reference is made to Figures 1 to 5 The second electrode 2223 of the outer frame 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 this utility model provides a second purification unit. For other features and effects of the gas particulate matter purification device, please refer to Embodiment 1. In addition, this embodiment only describes the differences from the second purification unit in Embodiment 1, and the same features will not be described again.

[0207] Reference Figures 8 to 13The second purification unit 60 includes multiple first electrodes 611 and multiple second electrodes 612. The second electrodes 612 are grounded and form an electric field with the first electrodes 611 for particulate matter adsorption. The first electrodes 611 and second electrodes 612 are hollow tubes of different diameters. The first electrodes 611 and second electrodes 612 are coaxially mounted and alternately arranged from the axis outwards. The second adsorption unit 60 also includes an upper connecting bracket 613 and a lower connecting bracket 614. The upper connecting bracket 613 is disposed at one end 6111 of the first electrodes 611 and electrically connects and fixes the multiple first electrodes 611 together. The lower connecting bracket 611... 4. A plurality of second electrodes 612 are electrically connected and fixed together at one end 6112 of the second electrode 612. A first opening 6113 is formed between the other ends 6112 of the adjacent first electrode 611, and a second opening is formed between the other ends of the adjacent second electrode (not shown in the figure, but can be understood by referring to the first electrode 611). The plurality of first electrodes 611 connected together are inserted into the plurality of second electrodes 612 connected together from the second opening, and the plurality of second electrodes 612 connected together are inserted into the plurality of first electrodes 611 connected together from the first opening 6113, so that the first electrode 611 and the second electrode 612 are alternately arranged in sequence.

[0208] This design results in a simple structure that is less prone to short circuits in the second purification unit.

[0209] In one embodiment of this utility model, reference is made to Figures 8 to 13 The second adsorption unit 61 also includes an insulating positioning connection mechanism 615. The upper end 6151 of the insulating positioning connection mechanism 615 is disposed in the innermost first electrode 6114 and positioned and connected to the upper connecting bracket 613. The lower end 6152 of the insulating positioning mechanism 615 is disposed in the innermost second electrode 6122 and positioned and connected to the lower connecting bracket 614, so that when the multiple first electrodes 611 and multiple second electrodes 612 are installed in an inter-insertion manner, the distance between the first electrodes 611 and the second electrodes 612 is the same.

[0210] Specifically, the insulating positioning connection mechanism 615 can be a column-shaped structure, an "I"-shaped structure, or a frustum-shaped structure, etc.; the upper end 6151 and the lower end 6152 of the insulating positioning connection mechanism 615 can have the same or different dimensions; when the upper end 6151 of the insulating positioning connection mechanism 615 is located at the innermost first electrode 6114, the side portion 61511 of the upper end 6151 can be adapted to the inner surface dimension of the innermost first electrode 6114 or not; the side portion 61522 of the lower end 6152 can be adapted to the inner surface dimension of the innermost second electrode 6122 or not.

[0211] Specifically, for example, the insulating positioning connection mechanism has 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 material than a cylindrical structure.

[0212] Specifically, for example, when the side portion 61511 of the upper end 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, it can be positioned by the connecting screws between the upper end 6151 and the upper connecting bracket 613, or between the lower end 6152 and the lower connecting bracket 614. If the first electrode 611 and the second electrode 612 are cylindrical, and the center of the upper connecting bracket 613 and the center of the lower connecting bracket 614 are concentric, the center of the upper end 6151 and the upper connecting bracket 614 can be aligned. The center of 613 is connected with a screw, the center of the lower end 6152 is connected with the center of the lower connecting bracket 614 with a screw, 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. It is planned that after assembly, the radius difference between adjacent first electrodes 611 and second electrodes will be L. When connected by mutual insertion, since the centers are aligned, the distance between the first electrodes 611 and the second electrodes 612 is L.

[0213] In one embodiment of this utility model, reference is made to Figures 8 to 13The outer diameter of the side portion 61511 of the upper end 6151 is adapted to the inner surface size of the innermost first electrode 6114, and the outer diameter of the side portion 61521 of the lower end 6152 is adapted to the inner surface size of the innermost second electrode 6122. The lower end 6152 is placed on the innermost second electrode 6122. During insertion and installation, the innermost first electrode 6114 moves along the side portion 61511 of the upper end 6151 to position the distance between the first electrode 611 and the second electrode 612. Alternatively, the upper end 6151 is disposed on the innermost first electrode 6114. During insertion and installation, the innermost second electrode 6122 moves along the side portion 61521 of the lower end 6152 to position the distance between the first electrode 611 and the second electrode 612.

[0214] This design achieves the following effects:

[0215] (1) Easy to install;

[0216] (2) The gas flows in from one end 6121 of the second electrode 612. When the side 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 inlet of the innermost second electrode 6122 is blocked by the lower end 6152. The insulating positioning connection mechanism 615 will not be contaminated. For example, the upper end 6151 and the support 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, which can stabilize the electric field of the second electrode 611 and the second electrode 612 and prevent short circuits.

[0217] Specifically, refer 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, and the distance between the second electrodes 612 is 2L. The side portion 61511 of the upper end 6151 and the side portion 61521 of the lower end 6152 differ in size by 2L. For example, the first electrode 611 and the second electrode 612 are cylindrical, and the upper end 6151 and the lower end 6152 are cylindrical. The outer diameter (outer circle diameter) of the cylindrical upper end 6151 and the cylindrical lower end 6152 differs by 2L, that is, the outer circle radius differs by L.

[0218] In one embodiment of this utility model, reference is made to Figures 8 to 13 The upper end 6151 is disposed in one end 6111 of the innermost first electrode 6114, and the lower end 6152 is disposed in one end 6121 of the innermost second electrode 6122.

[0219] This design facilitates the connection of the upper end 6151 to the upper connecting bracket 613 and the lower end 6152 to the lower connecting bracket 614.

[0220] In one embodiment of this utility model, reference is made 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 with the first opening 6113, and there is a height difference H between the end 6111 of the first electrode 611 connected to the upper connecting bracket 613 and the end of the second electrode 612 with the second opening.

[0221] With this design, since the upper connecting bracket 613 and the lower connecting bracket 614 are made of conductive materials, a short circuit would occur if there were no height difference H. 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 materials, 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 this utility model, reference is made to Figures 8 to 13 The height difference H is determined by the length of the insulating positioning connection mechanism 615. Since one end of the first electrode 611 and the second electrode 612 are assembled in a plug-in manner and the other end is connected to the insulating positioning connection mechanism 615 located inside, 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 this utility model, reference is made to Figures 8 to 13 The upper connecting bracket 613 includes a fixing plate 6131 and conductive mounting members 6132. Multiple conductive mounting members 6132 are arranged circumferentially around the fixing plate 6131 in a radial pattern. Each conductive mounting member 6132 has side plates 6134 on both sides, each side plate 6134 having multiple electrode mounting slots 6133 for fixing the first electrode 611. The upper end 6151 is connected to the fixing plate 6131. ​​The lower connecting bracket 614 has a similar structure to the upper connecting bracket 613, but its dimensions differ from the upper connecting bracket 613 to accommodate first and second electrodes of different sizes. The lower connecting bracket 614 includes a fixing plate and conductive mounting components. Multiple conductive mounting components are arranged circumferentially around the fixing plate in a radial pattern. The conductive mounting components have side plates 6134 on both sides. The side plates 6134 have multiple electrode mounting grooves for fixing the second electrode. The lower end is connected to the fixing plate. For ease 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 this utility model, reference is made to Figure 10 The conductive mounting component 6132 includes a main plate 6135. Two side plates 6134 are formed by bending downwards on both sides of the main plate 6135. An electrode mounting groove 6133 is disposed through the side plates 6134 and a portion of the main plate 6135. When the first electrode or the second electrode is installed in the electrode mounting groove 6133, it is first inserted into the electrode mounting groove 6133 of the side plate 6134, and then inserted into the electrode mounting groove 6133 of the main plate 6135, thus completing the installation of the first electrode or the second electrode within the electrode mounting groove 6133. Alternatively, the electrode mounting groove 6133 may only be disposed through the side plate 6134. In this case, the first electrode or the second electrode is inserted into the electrode mounting groove 6133 of the side plate 6134, thus completing the installation of the first electrode or the second electrode within the electrode mounting groove 6133.

[0225] In one embodiment of this utility model, reference is made 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 6124. The periphery of the insulating top plate 62 is inserted into the upper extension 6124 of the outermost second electrode 6123. The inner side of the insulating top plate 62 is connected to the upper connecting bracket 613.

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

[0227] In one embodiment of this utility model, reference is made to Figures 8 to 13 The insulating top plate 62 is provided with air holes.

[0228] In one embodiment of this utility model, reference is made to Figures 8 to 13 The other end of the outermost second electrode 6123 extends along the length direction to form a lower extension 6125, and the second discharge beam is disposed in the lower extension 6125.

[0229] Example 4

[0230] One embodiment of this utility model provides a second purification unit. For other features and effects of the gas particulate matter purification device, please refer to Embodiment 1. In addition, this embodiment only describes the differences between the second purification unit and the second purification unit in Embodiments 1 and 3, and the similarities will not be repeated.

[0231] Reference Figures 14 to 18The second purification unit 70 includes a first electrode 71 and a second electrode 72, both of which are hollow tubes with different diameters. The first electrode 71 and the second electrode 72 are coaxially mounted and are alternately arranged from the axis to the outer periphery. The second purification unit 70 also includes an upper connecting bracket 73 and a lower connecting bracket 74. The upper connecting bracket 73 is disposed at one end of the first electrode 71 and electrically connects and fixes multiple first electrodes 71 together. The lower connecting bracket 74 is disposed at one end of the second electrode 72 and electrically connects and fixes multiple 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. Multiple connected first electrodes 71 are inserted into the multiple connected second electrodes 72 through the second opening, and multiple connected second electrodes 72 are inserted into the multiple connected first electrodes 71 through the first opening, so that the first electrode 71 and the second electrode 72 are alternately arranged.

[0232] In one embodiment of this utility model, reference is made to Figures 14 to 18 The upper connecting bracket 73 fixes multiple first electrodes 71 together at equal intervals, and the lower connecting bracket 74 electrically connects and fixes multiple second electrodes 72 together at equal intervals.

[0233] In one embodiment of this utility model, reference is made to Figures 14 to 18 The second purification unit 70 also includes an insulating positioning bracket 75 disposed above the upper connecting bracket 73. The insulating positioning bracket 75 includes a positioning post 751 and a positioning element 752. The positioning post 751 is positioned with the upper connecting bracket 73. When multiple first electrodes 71 and multiple second electrodes 72 are installed in an interlocking manner, the positioning element 752 is engaged with the outermost second electrode 721 to maintain a certain distance between the first electrodes 71 and the second electrodes 72. When the second purification unit 70 includes multiple first electrodes 71 and multiple second electrodes 72, the insulating positioning bracket 75 can make the distance between the first electrodes 71 and the second electrodes 72 the same; when the second purification unit 70 includes one first electrode 71 and one second electrode 72, the insulating positioning bracket 75 can maintain a certain distance between the first electrode 71 and the second electrode 72. "Positioning of positioning post 751 and upper connecting bracket 73" can be understood as positioning post 751 being directly connected to the first electrode 71, or positioning post 751 being indirectly connected to the first electrode 71. The scheme of "positioning post 751 being connected to upper connecting bracket 73 and upper connecting bracket 73 fixing the first electrode 71" in the following text means that positioning post 751 is indirectly connected to the first electrode 71.

[0234] With this design, since all the first electrodes 71 are equidistant and concentric, and all the second electrodes 72 are equidistant and concentric, the positioning post 751 of the insulating positioning bracket 75 is connected to the upper connecting bracket 73. That is to say, 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 member 752 of the insulating positioning bracket 75, it drives all the second electrodes 72 to move and be positioned along the positioning member 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 this utility model, reference is made to Figures 14 to 18 The positioning element 752 is a circular positioning element 752 and has a stop groove 753. The outermost second electrode 721 is connected to the positioning element 752 by being inserted into the stop groove 753.

[0236] Specifically, the annular positioning component 752 includes an upper annular component 754 and a lower annular component 755 in the length direction. The outer diameter of the upper annular component 754 is larger than that of the lower annular component 755. Due to the difference in outer diameter, a stop groove 753 is formed at the connection between the upper annular component 754 and the lower annular component 755. When multiple first electrodes 71 and multiple second electrodes 72 are installed in an interlocking manner, the outermost second electrode 721 is fitted onto the outer side of the lower annular component 755 and is engaged in the stop groove 743, where it is stopped. "Engaged" can mean either a snap-fit ​​or not. When "engaged" does not indicate a snap-fit, it means that the outermost second electrode 721 is engaged in the stop groove 743, preventing the outermost second electrode 721 from moving forward. The outermost second electrode 721 and the annular positioning component 752 can be connected by adhesive, screws, etc. The length direction refers to the length direction of the hollow tubular first electrode or second electrode.

[0237] With this design, when the outermost second electrode 721 moves along the lower ring 755 and stops at the stop groove 753, it drives all the second electrodes 72 to move along the lower ring 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 this utility model, reference is made to Figures 14 to 18 The insulating positioning bracket 75 also includes a connecting bracket 756, the positioning element 752 is a circular positioning element 752, the connecting bracket 756 is disposed inside the circular positioning element 752, and the positioning post 751 is disposed below the connecting bracket 756.

[0239] In one embodiment of this utility model, reference is made to Figures 14 to 18The connecting frame 756 includes a central frame 7561 and a plurality of connecting rods 7562 disposed around the central frame 7561. The two ends of the connecting rods 7562 are respectively connected to the annular positioning member 752 and the central frame 7561. A positioning post 751 is provided below each connecting rod 7562.

[0240] In one embodiment of this utility model, reference is made to Figures 14 to 18 The insulating positioning bracket 75 includes a metal bracket 757, which is disposed between the positioning post 751, the connecting frame 756, and the positioning element 752, and is located directly below the connecting frame 756 and the positioning element 752. The positioning post 751 is made of ceramic material.

[0241] With this design, when the positioning post 751 is made of ceramic and the metal bracket 757 is positioned above it, flame retardancy is achieved. There have been previous cases of combustion in industrial electric fields. For example, in environments with high humidity, severe arcing between the two electrodes can cause sparking, leading to the combustion of the plastic components connecting the electrodes. While the connecting bracket 756 and positioning element 752 are typically made of insulating plastic, by replacing the connecting element with ceramic and adding a metal bracket, even if the two electrodes arc, it may not necessarily lead to the combustion of the insulating plastic.

[0242] Specifically, refer to Figures 14 to 18 The metal support 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 support 757, and the multiple connecting rods 7573 are located 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 support 757 are located directly below the connecting rods 7562 of the connecting frame 756. A gas flow channel is formed between the first electrode 71 and the second electrode 72. The orthographic projection of the metal support 757 on the gas flow channel covers the orthographic projections of the ring positioning member 752 and the connecting frame 756. It is precisely because of this blocking structure that the combustion of fire can be hindered.

[0243] In one embodiment of this utility model, reference is made to Figures 14 to 18The upper connecting bracket 73 includes a conductive mounting member 731, which includes a main body plate 7311. The two sides of the main body plate 7311 are bent upwards or downwards to form two side plates 7312. Each side plate 7312 has multiple electrode mounting slots 732 for fixing the first electrode 71 or the second electrode 72. Alternatively, both the side plates 7312 and the main body plate 7311 may have multiple electrode mounting slots 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 described above for the upper connecting bracket 73.

[0244] In one embodiment of this utility model, reference is made to Figures 14 to 18 The upper connecting bracket 73 also includes a fixing plate 732, with multiple conductive mounting elements 731 arranged circumferentially in a radial pattern 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 inside the innermost electrode. The annular fixing plate can be fitted onto the outside of the battery cell for fixed installation, while the solid circular fixing plate can be set on the upper or lower part of the battery cell for fixed installation.

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

[0246] In one embodiment of this utility model, reference is made to Figures 14 to 18 The two sides of the main plate 7311 are bent upward to form two side plates 7312. The electrode mounting groove 732 is disposed through the main plate 7311 and part of the side plates 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, so that the first electrode 71 is finally installed in the electrode mounting groove 732.

[0247] In one embodiment of this utility model, reference is made to Figures 14 to 18 The outer end of the conductive mounting component 731 is connected to the outermost first electrode or the outermost second electrode. The outermost electrode is the outermost second electrode 721. The outer end of the conductive mounting component of the lower connecting bracket 74 is connected to the outermost second electrode 721, which can be riveted.

[0248] In one embodiment of this utility model, reference is made to Figures 14 to 18When multiple first electrodes 71 and multiple second electrodes 72 are installed in an inter-insertion manner, there is a certain distance between the end of the first electrode 71 and the lower connecting bracket 74, and a certain distance between the end of the second electrode 72 and the upper connecting bracket 73.

[0249] With this 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 guaranteed. If there is no distance, a short circuit will occur.
