[0022] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.
[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0024] Reference Figures 1-4 An ionization collection device applicable to industrial applications includes: an outer frame 1 and an ionization section and a collection section disposed therein; the ionization section includes at least one set of stainless steel sawtooth ionization generators 10 and ionization zone guide plates 9, the stainless steel sawtooth ionization generators 10 having a tip sawtooth structure with a radius of curvature of less than 0.5 mm, a spacing of 28-30 mm between adjacent sawtooths, and each sawtooth arranged in an arc to form a discharge structure; the radius of curvature of the sawtooth tips of the stainless steel sawtooth ionization generators 10 varies in a gradient; the collection section includes a negative electrode collection plate 2 and a positive electrode collection plate 3, the positive electrode collection plate 3 and the negative electrode collection plate 2 are arranged in a wavy cross matrix, and the spacing between adjacent plates is 5-7 mm.
[0025] The ionization zone connection plate 6 is mounted on the outer frame 1, providing a mounting base and support for other components. It is made of a material with good insulation properties and high mechanical strength to ensure safety and stability under high-voltage environments.
[0026] The stainless steel sawtooth ionizer 10 features a unique sawtooth tip structure, with each sawtooth arranged in an arc to form a discharge structure. This design enables the ionizer to generate a high potential gradient during operation, effectively improving ionization efficiency. Furthermore, the radius of curvature at the sawtooth tips of the stainless steel sawtooth ionizer 10 varies gradient, an optimization design based on a theoretical model of electric field distribution and ionization efficiency. Sawtooth tips with different radii of curvature at different locations can generate electric fields of varying intensities, thus ionizing polluted airflow more comprehensively and efficiently.
[0027] When the polluted airflow enters the ionization section, the guide vanes 9 in the ionization zone first guide and evenly distribute the airflow, allowing it to pass uniformly through the stainless steel sawtooth ionizer 10. Under the action of a high-voltage power supply, the sawtooth tips of the stainless steel sawtooth ionizer 10 generate a strong electric field, fully ionizing particulate pollutants (such as oil fumes, oil mist, or soot) in the passing polluted airflow, causing these particulate pollutants to acquire a positive charge. Due to the gradient change in the radius of curvature at the sawtooth tips, sawtooths at different positions can efficiently ionize pollutants of different particle sizes and properties, improving the ionization effect and adaptability of the entire ionization section.
[0028] After ionization in the ionization section, the positively charged pollutants enter the collection section with the airflow. Based on the principle that like charges repel and unlike charges attract, the positively charged pollutants are adsorbed onto the negative electrode collection plate 2. Due to the wavy, cross-matrix arrangement of the positive electrode collection plate 3 and the negative electrode collection plate 2, the pollutants can more fully contact and be adsorbed onto the negative electrode collection plate 2. For oily particulate pollutants, the droplets accumulated on the negative electrode collection plate 2 will flow down along the V-shaped oil guiding structure and can be collected and treated uniformly by an external collection device.
[0029] The ionization section and the collection section are connected by an overhead high-voltage electrostatic conduction structure, which includes a copper contact head 4 and a ceramic insulator 8. The copper contact head 4 has a hyperboloid contact end, with compression deformation controlled in the range of 0.2-0.5mm, contact pressure controlled in the range of 2-4N, and contact resistance less than 0.5mΩ. Both the copper contact head 4 and the ceramic insulator 8 are set on the ionization zone connecting plate 6 and the collection zone connecting plate 5.
[0030] The positive electrode collecting plate 3 and the negative electrode collecting plate 2 are arranged in a wave-shaped cross matrix to form a unique mountain-like structure, which increases the effective adsorption area of the plates. At the same time, it makes the airflow form a complex flow path in the collection section, prolonging the contact time between pollutants and the plates and improving the adsorption efficiency.
[0031] The hyperboloid design of the copper contact 4 ensures good electrical contact under various operating conditions. The hyperboloid contact end increases the contact area, reduces contact resistance, and ensures efficient and stable transmission of high-voltage power to the ionization and collection sections. Both the copper contact 4 and the ceramic insulator 8 are mounted on the ionization zone connecting plate 6 and the collection zone connecting plate 5.
[0032] The ceramic insulator features a layered, ring-skirt structure, which increases creepage distance and improves insulation performance. Simultaneously, the high-performance vitreous insulating glaze layer possesses excellent corrosion resistance and insulation properties. Its thickness and uniformity are specially designed to effectively prevent creepage and short circuits caused by moisture, conductive materials, and other factors in industrial environments, ensuring the electrical safety and stability of the entire device.
[0033] The ionization section includes: an ionization zone connecting plate 6, which is mounted on the outer frame 1; a stainless steel sawtooth ionization generator 10 and an ionization zone guide plate 9 are mounted on the ionization zone connecting plate 6.
[0034] The ionization zone connecting plate 6 includes a connecting fixing rod 7, which is installed on the ionization zone connecting plate 6. The ionization zone connecting plate 6 is connected to the stainless steel sawtooth ionization generator 10 and the ionization zone guide plate 9 through the connecting fixing rod 7. The stainless steel sawtooth ionization generator 10 and the ionization zone guide plate 9 are alternately arranged on the connecting fixing rod 7. The radius of curvature of the sawtooth at the inlet end of the ionization zone is 0.3-0.4 mm, and the radius of curvature of the sawtooth at the outlet end is increased to 0.5-0.6 mm. A silicone rubber sealing ring is provided on the connecting fixing rod 7.
[0035] The ceramic insulator 8 has a layered ring skirt structure and is coated with a glassy high-performance insulating glaze.
[0036] The collection section also includes: a collection area connecting plate 5, installed on the outer frame 1; negative electrode collection plate 2 and positive electrode collection plate 3 connected to the collection area connecting plate 5; the wave-shaped structure of positive electrode collection plate 3 and negative electrode collection plate 2 has a wave height of 5-7mm and a wavelength of 10-15mm, with the peaks and troughs of adjacent plates arranged alternately; a V-shaped oil guiding structure is provided at the bottom of negative electrode collection plate 2, and the angle and size of the V-shaped oil guiding structure have been optimized. When oily particulate contaminants are adsorbed on negative electrode collection plate 2 and accumulate to form droplets, the droplets can flow smoothly down along the V-shaped oil guiding structure, avoiding accumulation on the plates and ensuring the long-term stable operation of the collection section.
[0037] During operation, industrial pollutant airflow enters the ionization section. The guide vanes 9 in the ionization zone guide and evenly distribute the airflow, ensuring it passes uniformly through the stainless steel sawtooth ionizer 10. The ionization process involves the stainless steel sawtooth ionizer 10 operating under high-voltage power. It features a pointed sawtooth structure with a radius of curvature less than 0.5 mm and a spacing of 28-30 mm between adjacent sawtooths. The sawtooths are arranged in an arc shape to form a discharge structure. Furthermore, the radius of curvature at the sawtooth tips varies gradually, with a radius of curvature of 0.3-0.4 mm at the inlet and increasing to 0.5-0.6 mm at the outlet. The sawtooths with different radii of curvature generate electric fields of varying intensities, ionizing particulate pollutants (such as oil fumes, mist, or dust) in the passing polluted airflow. This imparts a positive charge to these particulate pollutants, improving the ionization effect and adaptability of the entire ionization section.
[0038] After ionization, the positively charged pollutants enter the collection section with the airflow. Based on the principle of like charges repelling and unlike charges attracting, the positively charged pollutants are adsorbed onto the negative electrode collection plate 2. The wave-shaped, intersecting matrix arrangement of the positive and negative electrode collection plates 3 and 2 increases the effective adsorption area of the plates, creating a complex flow path within the collection section. This prolongs the contact time between the pollutants and the plates, improving adsorption efficiency. For oily particulate pollutants, after accumulating into droplets on the negative electrode collection plate 2, the droplets flow down along the optimized V-shaped oil guide structure at the bottom, and are uniformly collected and treated by an external collection device, preventing accumulation on the plates and ensuring long-term stable operation of the collection section.
[0039] In summary, compared with existing technologies, it has the following beneficial effects:
[0040] The stainless steel serrated ionization generator and the cross-matrix mountain-like collection section electrode structure greatly improve the ionization collection efficiency and enable long-term stable operation.
[0041] The copper contact head 4 device avoids the generation of electric arcs, and the overhead high-voltage electrostatic conduction technology and special insulation technology structure prevent short circuits, eliminate safety hazards, and make the device safe and reliable in operation.
[0042] This device has high purification efficiency and low power consumption, which not only reduces operating and maintenance costs, but also reduces energy consumption.
