Method and device for controlling precise measurement of hydrogen sulfide pulsation injecting liquid through pressure degenerative feedbacks

Abstract

The invention relates to a method for controlling precise measurement of hydrogen sulfide pulsation injecting liquid through pressure degenerative feedbacks. The method comprises the steps of placing articles to be disinfected in a sterile chamber for disinfection; using a vacuum system to extract vacuum or inflate for the sterile chamber in which the articles to be disinfected are placed; using a plasma generating device to excite the generation of plasmas; using pressure variation signals obtained by a testing control system in the sterile chamber to control a hydrogen peroxide injecting system and determine the dosage of an injected hydrogen peroxide disinfectant, and the injected hydrogen peroxide is excited by the plasmas. Thus, the hydrogen peroxide medium in the plasmas is fully excited, too much or too little injection of the hydrogen peroxide is prevented and precise control of the dosage of the hydrogen sulfide is achieved.

Description

technical field [0001] The invention relates to a sterilizing method for a plasma sterilizer, and more particularly, to a method and a device for controlling the precise metering of hydrogen peroxide pulsating liquid injection through pressure negative feedback. Background technique [0002] Plasma is a special form of matter widely existing in nature (the fourth form other than gaseous, liquid, and solid), a high-energy material aggregation state. There are not only molecules and atoms, but also many charged particles that make up the plasma. The energy of the particles ranges from several eV to several thousand eV. Therefore, it has special physical and chemical properties, and will produce many Special physical and chemical effects. Plasma sterilization technology is a new physical sterilization technology that has emerged in the field of disinfection in recent years. The sterilization technology using hydrogen peroxide plasma as a sterilizing agent has significant advan...

Problems solved by technology

[0003] Common hydrogen peroxide injection methods for plasma sterilizers include: capsule puncture injection method, secondary heating atomization injection method, ultrasonic atomization injection method, etc. The above methods can realize the hydrogen peroxide injection of the sterilizer injection, but the dosage of hydrogen peroxide cannot be controlled. When the dosage of hydrogen peroxide medium added is too small, it may cause incomplete disinfection, cause equipment pollution, and cause serious hazards. If too much hydrogen peroxide medium is added, it will decompose If it is not complete, there will be residual hydrogen peroxide on the surface of the disinfected items, and the residual hydrogen peroxide will cause harm to the user and affect the health of the user
