Online plasma sterilizing device and method for refrigeration house

Abstract

The invention discloses an online plasma sterilizing device for a refrigeration house. The online plasma sterilizing device comprises a main draught fan device and an auxiliary draught fan device. The main draught fan device comprises a centrifugal fan arranged on a front side wall of the refrigeration house and a plasma generation device. The auxiliary draught fan device comprises a left auxiliary draught fan, a rear auxiliary draught fan and a right auxiliary draught fan, all of which are arranged on the other three side walls of the refrigeration house correspondingly. The centrifugal fan, the left auxiliary draught fan, the rear auxiliary draught fan and the right auxiliary draught fan are arranged in the same direction in an anticlockwise or clockwise manner. An air flowing direction fan is downwards vertically hung to the center of the top face of the refrigeration house, and the rotation direction of the air flowing direction fan is the same as the arranging direction of the centrifugal fan and the auxiliary draught fan device.

Description

technical field [0001] The invention relates to the technical field of plasma sterilization, in particular to an online plasma sterilization device and a sterilization method for cold storage. Background technique [0002] There are many commonly used disinfection and sterilization methods, such as high-temperature steam sterilization, low-temperature ethylene oxide sterilization and radiation sterilization. Various methods have unique characteristics, scope of application and limitations. For some heat-sensitive, moisture-resistant and high-temperature utensils and materials, both rapid sterilization and the absence of pyrogens are required. Obviously, ethylene oxide The alkane chemical disinfection method is quite suitable, but this method has a long disinfection cycle (nearly 20 hours), and ethylene oxide (EtO) can cause mutations in human genes, is a first-class carcinogen, and is colorless and tasteless. It is very dangerous: and the dilution of EtO, freon, has a destr...

Various methods have unique characteristics, scope of application and limitations. For some heat-sensitive, moisture-resistant and high-temperature utensils and materials, both rapid sterilization and the absence of pyrogens are required. Obviously, ethylene oxide The alkane chemical disinfection method is quite suitable, but this method has a long disinfection cycle (nearly 20 hours), and ethylene oxide (EtO) can cause mutations in human genes, is a first-class carcinogen, and is colorless and tasteless. It is very dangerous: and the dilution of EtO, freon, has a destructive effect on the ozone layer, which is not conducive to environmental protection.
