(Summary description)How to improve the plasma plasma cleaner to make it better after the discharge problem in the treatment chamber occurs: The plasma plasma cleaner manufactured by Chengfeng Zhizhi introduces you to the ideal PEF plasma treatment process. The electric field in the treatment room is evenly distributed, which can greatly reduce the influence of the treatment process on the raw materials. In the actual PEF plasma processing equipment, when the electric field strength is high, the insulation of the liquid raw materials in the processing chamber is easily destroyed and discharges. In short, on the one hand, the gas dissolved in the liquid, due to the temperature rise or continuous flow during processing, is easy to overflow in the processing area and form bubbles. The dielectric constant of the bubbles is much smaller than that of the liquid. Therefore, the pulse voltage is basically applied to the bubbles. , Resulting in bubble breakdown. In addition, due to the improper design of the electrode in the treatment chamber of the plasma plasma cleaner, the surface of the electrode produced non-smooth tiny metal bumps, resulting in uneven electric field distribution in the treatment area, and local strong distortions turned into concentrated currents, which caused the local liquid to heat and vaporize. Air bubbles cause liquid insulation breakdown. In addition, the liquid raw material contains solid particles, which are prone to discharge at the interface between the liquid and the solid particles, or when its electrical conductivity is high, the leakage current will increase through the passage, the heat phenomenon in the solution will increase, and the breakdown probability of the processing chamber will increase. Dealing with emissions during the indoor use stage is currently an important issue that is widely faced. When the pressure in the treatment chamber is constant, the appearance of bubbles in the liquid in the treatment chamber will have a significant impact on the electric field distribution in the treatment chamber, which increases the possibility of discharge breakdown in the treatment chamber of the plasma plasma cleaner. If a bubble with a diameter greater than 1mm is located in a processing chamber with a spacing of less than 3mm, its dielectric breakdown threshold voltage is much greater than a bubble with a diameter of less than 0.5mm in a processing chamber with a spacing greater than 5mm. In order to reduce the dead zone of the flow velocity and the local high temperature zone, and reduce the possibility of generating bubbles on the flow path, the structure of the plasma plasma cleaning machine processing chamber should be adjusted, or the tubular electrode of the same field processing chamber should be replaced with a mesh electrode, and in the same field. An insulating layer is added between the electrodes of the field treatment chamber to reduce the possibility of breakdown in the treatment chamber.
