Problems solved by technology

At present, most antibacterial agents on the market have the problems of short timeliness and high cost. Plasma activated water also has the problem that the active antibacterial ingredients cannot be stored for a long time. In most cases, it is used while preparing and cannot be stored in advance. or bulk save
[0003] In the field of sterilization, plasma-activated water cannot meet its long-lasting or long-distance storage and transportation conditions, such as household disinfection, mainly because the active antibacterial ingredients in the activated water have a short storage time, which leads to the need for short-term storage of activated water once it is prepared. Use within a short period of time increases the cost of activated water preparation and transportation, thereby limiting the application of activated water in sterilization and disinfection

Abstract

The invention relates to a device and method for preparing activated ice by air plasma, which comprises a sliding arc discharge plasma reactor, a condensation ice making mechanism and a sealed barrel body; the sliding arc discharge plasma reactor forms a seal with the sealed barrel body through pipelines Connected; the top spray area of ​​the sealed barrel is provided with a spray port connected to the water inlet pipe, the middle water uniform area is provided with an inner mesh layer, and the lower reaction area is provided with an air outlet structure connected with the air inlet; the condensing ice making mechanism has a sealed bucket The sealed barrel has an openable and closed ice outlet and a water inlet, and the water inlet communicates with the lower reaction zone of the sealed barrel. The invention has a simple structure, and the activated ice is directly prepared by activating water without adding any other ingredients, while ensuring that the effective active ingredients contained in it last for a long time, and still have good activity after melting or thawing, and will not cause secondary pollution to the environment, effectively Kill bacteria and viruses, and can be widely used in various disinfection and sterilization.

Description

technical field [0001] The invention belongs to the technical field of sterilization and disinfection, and in particular relates to a device and method for preparing activated ice by air plasma. Background technique [0002] The aqueous solution or medium treated with atmospheric low-temperature plasma is called plasma activated water or medium. This activated aqueous solution is rich in various active antibacterial ingredients, and has the characteristics of low pH value and high oxidation-reduction potential. It is a good , Green, non-polluting bactericidal preparations are expected to replace other traditional bactericidal preparations such as hypochlorous acid, electrolyzed water and ozone water. At present, most antibacterial agents on the market have the problems of short timeliness and high cost. Plasma activated water also has the problem that the active antibacterial ingredients cannot be stored for a long time. In most cases, it is used while preparing and cannot b...
