A flexible low temperature plasma sterilization device

Abstract

The invention discloses a flexible low-temperature plasma sterilization device used in narrow and long pipelines and other complex gap working environments. The device includes a flexible actuation system, a low-temperature plasma generation module, a power supply module and a sensor control module; it is characterized in that the power supply module and the sensor control module are connected to the low-temperature plasma generation module, and the low-temperature plasma generation module is assembled in the flexible actuation system. The device adopts a flexible actuation system to achieve the purpose of penetrating into the working environment of narrow and long pipes and other complex gaps; the device performs dielectric barrier discharge in the working environment, and excites the working gas into low-temperature plasma, so as to achieve the purpose of cleaning the narrow and long pipes and other complex gaps. Sterilization of the working environment.

Description

technical field [0001] The invention belongs to the field of plasma applications, in particular to the sterilization of long and narrow pipes and other complex working environments, and in particular to a flexible low-temperature plasma sterilization device. Background technique [0002] A continuous supply of energy to a substance to raise its temperature usually causes the substance to change from solid to liquid and then from liquid to gas. In the process of continuously supplying energy to the material system, the neutral atoms or molecules of the gas are excited by energy to produce negative electrons, positive and negative ions and other excited substances. This kind of charged mixture of excited particles is called plasma. The general way of generating plasma is the breakdown ionization of gas between two electrodes. Due to the ionized gas that contains a large number of negative electrons, positive and negative ions and free radicals, the plasma has unique physical ...

AI Technical Summary

Problems solved by technology

[0003] The plasma sterilization equipment currently used generally cannot efficiently deal with narrow and long pipes and other complex gap working environments due to the rapid annihilation of plasma, which makes the application of plasma sterilization equipment have great limitations.
