Embodiment 1

[0053] Figure 4 This is the case where one electrode is a flexible body. The flexible electrode a1 uses a cylindrical carbon fiber wire wrapped with an insulating medium (polytetrafluoroethylene). The other rigid electrode a2 is made of stainless steel tube and wrapped with insulating medium a3. The carbon fiber wire is wound on the stainless steel tube electrode in a spiral manner. The pitch (coil interval) is set according to the actual discharge area required, so that the two electrodes form a relatively uniform interface .

[0054] In particular, when the flexible electrode a1 uses bare carbon fiber wires (without additional insulating layer), a single-sided dielectric barrier discharge can be formed, which can effectively reduce the initial discharge voltage, and the amount of ozone generated is greatly reduced. Connecting this electrode structure to the power supply system of the embodiment, and placing the electrodes on the treated objects such as bed sheets and quil...

Embodiment 2

[0057] Figure 6 This is the case where both electrodes are flexible bodies. The two flexible electrodes can both use wires whose diameter is wrapped with insulating medium b3 (polytetrafluoroethylene), at least one electrode conductor is made of carbon fiber material, and the wire b1 is bent as follows according to actual needs Figure 6 In the desired shape, the wire b2 is helically wound on the wire b1, and the whole remains in the shape of the wire b1. It is also possible to twist the wires b1 and b2 together first, and then fold them into the desired shape. In particular, when one of the wires b1 and b2 is a bare carbon fiber wire, a single-sided dielectric barrier discharge is also formed, which can effectively reduce the initial discharge voltage, have better uniformity, and greatly reduce the amount of ozone generated. In the hospital ward, the schematic diagram of the disinfection and sterilization device system constructed by the flexible electrode combined with th...

Abstract

The invention discloses a plasma disinfection and sterilization device with a flexible discharge electrode structure, which includes a power supply system with a high-voltage output circuit, a high-voltage electrode connected to the high-voltage end of the high-voltage output circuit, and a grounding electrode. The high-voltage electrode and the grounding electrode In direct contact with each other in a spirally wound structure, at least one of the high-voltage electrodes and the grounding electrodes is a flexible body structure, and at least one of the high-voltage electrodes and the grounding electrodes is wrapped with an insulating medium; the grounding electrode with a flexible body structure has a high melting point and high conductivity. Better carbon fiber material; after the power system is energized, surface discharge occurs in the contact area of ​​the two electrodes, generating a large amount of low-temperature plasma; the high-voltage electrode and ground electrode structure that are entwined and directly in contact can sterilize the object to be processed in a direct contact manner bacteria treatment.

Description

technical field [0001] The invention belongs to the technical field of gas discharge plasma generation, and more specifically relates to a low-temperature plasma generation under atmospheric pressure, especially a plasma disinfection and sterilization device with a flexible discharge electrode structure and specific applications. Background technique [0002] The continuous development of human industrial society, on the one hand, has aggravated the damage to the natural environment, causing the gas to be seriously polluted; The demand is becoming stronger and stronger, for example, in hospital wards, the disinfection and sterilization effect and efficiency of medical equipment or hospital beds become particularly important. [0003] With the rapid development of plasma technology, its application is becoming wider and wider, and its good application effect in these fields is also constantly emerging. For example, in air purification, medical disinfection, etc., as a new ty...
