Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste gas ionization technology, and particularly relates to a dynamic ionization atmospheric pressure glow discharge device and an electrolysis chamber. Background Technology
[0002] In the field of industrial waste gas treatment, especially for the purification of complex components such as volatile organic compounds and odorous gases, electro-purification technology is widely used due to its advantages such as fast reaction speed, no need to add chemical reagents, and operation at normal temperature and pressure.
[0003] The core of mainstream electro-purification technology lies in its discharge device, which forms a non-equilibrium plasma, also known as "corona discharge," by applying high voltage to a specific reaction chamber. The high-energy electrons, ions, free radicals, and excited-state molecules generated in this process can collide with waste gas molecules and degrade pollutants into harmless or less harmful substances through a series of physicochemical reactions (such as breaking chemical bonds, oxidation, and decomposition).
[0004] However, despite the clear technical principle, most existing industrial devices based on corona discharge suffer from a fundamental and common technical bottleneck in practical applications: the energy conversion efficiency from electrical energy to effective active particles is extremely low. Under the same conditions of nine factors, including voltage, frequency, power, air pressure, temperature, humidity, dielectric constant, composition, and concentration, only 5% to 12% of electrical energy can be converted into high-energy ions. The vast majority of the input electrical energy is not used to generate high-energy ions or free radicals that can treat waste gas, resulting in severe energy path loss.
[0005] Another existing treatment method utilizes glow discharge. As a typical low-pressure, low-current-density discharge mode, glow discharge can generate large-area, uniform, and stable plasma under laboratory conditions. The high-energy electrons and active particles produced can effectively react with waste gas molecules, achieving pollutant degradation.
[0006] However, when improving the energy conversion efficiency from electrical energy to effectively active particles through glow discharge, it has been found that stable glow discharge typically requires a low pressure environment of one to several hundred Pascals to be maintained. Industrial waste gases are usually at or near atmospheric pressure. To create the vacuum environment required for glow discharge, a high-power, high-flow-rate vacuum pump system is necessary. Currently, no discharge device can achieve stable glow discharge at atmospheric pressure. Utility Model Content
[0007] The purpose of this invention is to provide a dynamic ionization atmospheric pressure glow discharge device and an electrolysis chamber, which aims to solve the problem that existing discharge devices cannot achieve stable glow discharge under atmospheric pressure.
[0008] To achieve the above objectives, the present invention provides a first technical solution: a dynamic ionization atmospheric pressure glow discharge device, comprising a spray head, a central conductive rod threadedly connected to the bottom of the spray head, a spiral discharge line curvature correction spring sleeved on the circumferential side of the central conductive rod, the discharge line curvature correction spring elastically deforming along the axial direction of the central conductive rod, one end of the discharge line curvature correction spring elastically abutting against the bottom of the spray head, and the other end of the discharge line curvature correction spring elastically contacting a 12-pointed star discharge plate, the thickness of the 12-pointed star discharge plate being 0.9–1.1 mm, a circular hole being provided in the center of the 12-pointed star discharge plate, and 12 barbs evenly distributed on the circumference of the circular hole, the apex of the barbs forming a first rounded corner structure with a radius of curvature of 0.2–0.3 mm, and the concave corner of the barbs forming a second rounded corner structure with a radius of curvature of 0.85–0.95 mm;
[0009] The peripheral side of the central conductive rod passes through the circular hole, allowing several 12-pointed star discharge plates to be fitted and fixed to the peripheral side of the central conductive rod. A conductive tube abuts between any two adjacent 12-pointed star discharge plates. The conductive tube is fitted onto the peripheral side of the central conductive rod, and the length of the conductive tube is 3.9–4.1 mm.
[0010] The bottom of the central conductive rod is threaded with a positioning nut for fixing the central conductive rod to the discharge wire bracket.
[0011] As an optional embodiment of this utility model, the top of the spray head is provided with an external thread, which is used to fix the spray head on the square tube grid frame; the bottom of the spray head is provided with an internal thread, which is used to connect with the central conductive rod.
[0012] As an optional solution of this utility model, the spray head is a regular hexagonal prism with a through hole on the central axis, and each prism surface above the internal thread has a spray hole on the center line, and the spray hole is connected to the through hole.
[0013] As an optional embodiment of this utility model, the top and bottom of the central conductive rod are respectively provided with a top external thread and a bottom external thread, the top external thread being threadedly connected to the internal thread; the bottom external thread being threadedly connected to the positioning nut.
[0014] As an optional embodiment of this utility model, the middle part of the central conductive rod is a smooth round rod, and the length of the smooth round rod is the sum of the thickness of the 12-pointed star discharge sheet and the total length of the conductive tube.
[0015] As an optional solution of this utility model, the elastic coefficient of the discharge line curvature correction spring is between 8 N / mm and 12 N / mm.
[0016] This utility model provides a second technical solution: a dynamic ionization atmospheric pressure glow discharge electrolysis chamber, comprising an electrolysis chamber body. The electrolysis chamber body is equipped with an air inlet device and an array of anode cylindrical discharge tubes. The top and bottom of the anode cylindrical discharge tube array are each provided with a square tube grid frame. A dynamic ionization atmospheric pressure glow discharge device is installed inside each anode cylindrical discharge tube. The square tube grid frame has threaded holes. The external thread at the top of the spray head is threaded to the threaded hole, and the external thread at the bottom passes through the threaded hole and is threaded to the positioning nut. The dynamic ionization atmospheric pressure glow discharge device is fixed between the square tube grid frames. When fixing the dynamic ionization atmospheric pressure glow discharge device, rotating the positioning nut causes the discharge wire curvature correction spring 2 to compress, generating an elastic deformation of 1mm to 3mm, so that the central conductive rod 1 and the 12-pointed star discharge plate 4 form good contact. A contact piece extends axially from both ends of the square tube grid frame, and an insulating terminal is installed on one side of each contact piece.
[0017] As an optional solution of this utility model, the distance from the barb to the wall of the anode cylindrical discharge tube is in the range of 19.3mm to 19.7mm.
[0018] As an optional embodiment of this invention, the discharge line curvature correction springs are all located on the same side of the anode cylindrical discharge tube array.
[0019] The above-mentioned technical solutions of one or more technical solutions in the dynamic ionization atmospheric pressure glow discharge device provided by this utility model embodiment have at least one of the following technical effects:
[0020] This application provides a dynamic ionization atmospheric pressure glow discharge device. A spray head is threadedly connected to the top of a central conductive rod, using an internal spraying method to clean deposits on the anode, preventing spray liquid from splashing onto the insulator and causing leakage. A spiral discharge wire curvature correction spring is fitted around the periphery of the central conductive rod. The two ends of the spring make elastic contact with a 12-pointed star discharge plate and the spray head, respectively, ensuring good contact between the 12-pointed star discharge plate and the central conductive rod and preventing bending deformation of the central conductive rod due to the pressure of the positioning nut. The 12-pointed star discharge plate has a central circular hole with 12 evenly distributed barbs on its circumference. The apex of the barbs forms a first rounded corner structure with a radius of curvature of 0.2–0.3 mm, and the concave angles of the barbs form a second rounded corner structure with a radius of curvature of 0.85–0.95 mm. This rounded corner design allows for a unit tip discharge point density of 0.772 cm⁻¹. 2The needle optimizes the electric field distribution on the spikes, enabling them to perform stable glow discharges under normal pressure. By connecting a conductive tube between two adjacent 12-pointed star discharge plates, the 12-pointed star discharge plates can be evenly installed on the central conductive rod. Furthermore, the flexible assembly method of the 12-pointed star discharge plates, which combines the conductive tube and the discharge line curvature correction spring, facilitates the replacement of damaged 12-pointed star discharge plates.
[0021] This application provides a dynamic ionization atmospheric pressure glow discharge electrolysis chamber. By controlling the distance from the barbs to the wall of the anode cylindrical discharge tube between 19.3mm and 19.7mm, the distance deviation from the barb discharge point to the anode is reduced, and the density of discharge points per unit bar tip is increased. The number of discharge points per unit area of the barbs is evenly distributed, reducing the volume and weight of the purification chamber, improving the production efficiency of the waste gas treatment purification chamber and reducing manufacturing costs, and improving the purification efficiency of the purification chamber for waste gas.

[0037] Reference Figure 1 and Figure 3 In a specific embodiment of this utility model, the central conductive rod 3 is preferably a smooth stainless steel round rod with a diameter of 4mm and a length of 86cm.

Both the top external thread 301 and the bottom external thread 302 are preferably M4 threads with a thread length of 6cm. The top external thread 301 is threadedly connected to the internal thread 103 for fixing the spray head 1 and the central conductive rod 3. The bottom external thread 302 is threadedly connected to the positioning nut 6, which is located at the junction of the bottom external thread 302 and the smooth circumferential side of the central conductive rod 3. The middle part of the central conductive rod 3 is a smooth round rod.
[0038] A spiral discharge wire curvature correction spring 2 is sleeved on the circumferential side of the central conductive rod 3. The outer diameter of the discharge wire curvature correction spring 2 is preferably 7 mm, the inner diameter is preferably 5 mm, the middle diameter is preferably 6 mm, and the wire diameter is preferably 1 mm. The shear modulus of the material of the discharge wire curvature correction spring 2 is preferably not less than 7 × 10⁻⁶. 10 The effective number of turns is preferably no more than 5, and the elastic coefficient is preferably between 8 N / mm and 12 N / mm.

[0039] Reference Figure 4 In a specific embodiment of this utility model, the envelope diameter of the 12-pointed star discharge sheet 4 is preferably 20 mm, the thickness ranges from 0.9 to 1.1 mm, and the thickness is preferably 1 mm. A circular hole 401 is provided in the center of the 12-pointed star discharge sheet 4, the diameter of which is preferably 4.2 mm. Twelve barbs 402 are evenly distributed on the circumference of the hole 401. The height of each barb 402 is not less than 4 mm, and the bottom width of each barb 402 is not greater than 3.2 mm. The apex of the barb 402 forms a first rounded corner structure 403, the radius of curvature of which is 0.2–0.3 mm, preferably 0.25 mm; the concave corner of the barb 402 forms a second rounded corner structure 404, the radius of curvature of which is 0.85–0.95 mm, preferably 0.9 mm.

[0040] Reference Figure 1The smooth circumferential surface of the central conductive rod 3 passes through the circular hole 401, allowing several 12-pointed star discharge plates 4 to be fitted and fixed on the circumferential surface of the central conductive rod 3. In a specific embodiment of this utility model, 154 plates are preferred. A conductive tube 5 abuts between any two adjacent 12-pointed star discharge plates 4. The conductive tube 5 is fitted on the circumferential surface of the central conductive rod 3, and the two circular surfaces of the conductive tube 5 are perpendicular to the axis of the conductive tube 5, so that the 12-pointed star discharge plates 4 can be evenly installed on the central conductive rod 3. The outer diameter of the conductive tube 5 is preferably 6 mm, the inner diameter is preferably 4.4 mm, the wall thickness of the conductive tube 5 is preferably 0.8 mm, and the length of the conductive tube 5 is 3.9 to 4.1 mm, preferably 4 mm. The design of the conductive tube 5 and the 12-pointed star discharge plate 4 being adjacent to each other can uniformly deploy micro-discharge points (thorns 402) on the periphery of the central conductive rod 3. When the number of micro-discharge points is sufficient and the distribution is uniform, the electrical energy conducted by the central conductive rod 3 is dispersed to several micro-discharge points, avoiding the energy concentration at one micro-discharge point and causing an electric arc. The plasma plumes generated by the micro-discharge points will overlap and merge with each other, eventually forming a uniform and diffuse discharge layer, thus achieving stable glow discharge under normal pressure.
[0041] When assembling the dynamic ionization atmospheric pressure glow discharge device, the 12-pointed star discharge plate 4 and the conductive tube 5 are sequentially abutted along the axial direction of the central conductive rod 3, with the positioning nut 6 as the reference point, until the total length of the sequentially abutted 12-pointed star discharge plate 4 and the conductive tube 5 is equal to the length of the smooth round rod. Then, the discharge wire curvature correction spring 2 is sleeved along the axial direction of the central conductive rod 3, and the sleeved discharge wire curvature correction spring 2 abuts against the uppermost 12-pointed star discharge plate 4. Next, the spray head 1 is screwed in along the top external thread 301, so that the bottom of the spray head 1 abuts against the discharge wire curvature correction spring 2. The positioning nut 6 is turned to compress the discharge wire curvature correction spring 2 by 1mm to 3mm, thus completing the assembly of the dynamic ionization atmospheric pressure glow discharge device.
[0042] The flexible assembly of the 12-pointed star discharge plate 4, combining the conductive tube 5 and the discharge wire curvature correction spring 2, facilitates the replacement of damaged 12-pointed star discharge plates 4. The elastic contact of the discharge wire curvature correction spring 2 ensures good contact between the 12-pointed star discharge plate 4 and the central conductive rod 3, and prevents the central conductive rod from bending and deforming due to the compression of the positioning nut 6.

The bottom external thread 302 passes through the first threaded hole 801. 01 is threadedly connected to another positioning nut 6, fixing the dynamic ionization atmospheric pressure glow discharge device 10 between the two square tube grid frames 8, achieving precise positioning of the dynamic ionization atmospheric pressure glow discharge device 10. By tightening the positioning nut 6 at the bottom of the square tube grid frame 8, an upward pulling force is generated on the central guide rod 3, enabling the dynamic ionization atmospheric pressure glow discharge device 10 and the square tube grid frame 8 to form a stable rigid suspension, ensuring that the dynamic ionization atmospheric pressure glow discharge device 10 is always located in the middle position of the anode cylindrical discharge tube 701, so as to ensure a constant electrode spacing and achieve a discharge distance deviation of less than 1%. Both ends of the square tube grid frame 8 have a contact piece 802 extending axially. A second threaded hole 803 is provided on one side of the contact piece 802. An insulating terminal 9 is installed on one side of the contact piece 802 through the second threaded hole 803 and the bolt.
