High voltage pulse electric field sterilization common-field treatment chamber with adjustable electrode distance

Abstract

The invention discloses a high voltage pulse electric field sterilization common-field treatment chamber with adjustable electrode distance. The treatment chamber consists of two metallic hollow tubular electrodes and an insulator isolation tube, wherein the insulator isolation tube is positioned in a treatment cavity formed between the two metallic hollow tubular electrodes. The metallic hollow tubular grounding electrodes are in threaded fit with the insulator isolation tube, so that the adjustability of the electrode distance in the common-field treatment chamber is realized. The inner ports of the metallic hollow tubular electrodes in the treatment chamber are rounded, so that the strength of a peak electric field nearby the electrodes is reduced, the 'discharge' problem caused by over high local electric field in the treatment chamber is solved, and the electric field in the flowing direction of a material is distributed relatively uniformly. The treatment chamber is simple in structure, low in cost, convenient to process and convenient to disassemble and assemble; the adjustability of the electrode distance in the common-field treatment chamber is realized; and the electrode distance in the treatment chamber can be adjusted according to different application requirements, so that the electric field strength and the electric field distribution in the treatment chamber are improved.

AI Technical Summary

Problems solved by technology

The electric field strength in the processing chamber depends entirely on the high-voltage pulse generator. The high-voltage pulse generator generates extremely high voltage, the square wave pulse width is small, and the pulse frequency is fast. Its technology is difficult and costly. These problems seriously restrict the high-voltage pulse generator. Development and Application of Pulse Electric Field Sterilization Technology
