Embodiment 1

[0050] figure 1 A schematic diagram of an embodiment of the present invention is shown;

[0051] A device for preparing activated water by air plasma, comprising a sliding arc discharge reactor, an air circulation device, a sealed cavity 5 and a water holding space;

[0052] The air circulation device includes a housing and a fan 1 arranged in the housing; the housing has an air inlet and an air outlet; the air inlet and the air outlet are respectively communicated with the sealed cavity 5, and the air flow A sealed communication arrangement is formed between the circulation device and the sealed cavity 5;

[0053] The sliding arc discharge reactor includes a power supply 7 and two opposite electrodes; the power supply 7 is connected to the electrodes; that is, the high voltage end of the power supply is connected to one electrode, and the low voltage end is connected to the other electrode;

[0054] The gas outlet is an insulated high temperature resistant pipe 2, or the ga...

Embodiment 2

[0071] see figure 2 , and the difference from Embodiment 1 is that the circulating pump is located inside the cavity, and the water container is located outside the cavity.

Embodiment 3

[0073] see image 3 , different from Embodiments 1 and 2, this Embodiment 3 does not have an independent water container, the cavity itself constitutes a water storage space, and the air outlet of the insulated high temperature resistant pipe is located in the sealed cavity and located in the Below the liquid level in the water holding space, the air outlet of the insulated high temperature resistant pipe leads to the inside of the deionized water.

[0074] Specifically, the lower half of the sealed cavity is provided with an openable and closable water outlet.

Abstract

The invention relates to a device and a method for preparing activated water by using air plasma. The device comprises a gliding arc discharge reactor, an airflow circulating device, a sealed cavity and a water containing space; the airflow circulating device comprises a shell and a fan arranged in the shell; the shell is provided with an air inlet end and an air outlet end; the air inlet end and the air outlet end are respectively communicated with the sealed cavity, and the air flow circulating device is hermetically communicated with the sealed cavity; the gliding arc discharge reactor comprises a power supply and two electrodes which are oppositely arranged; the power supply is connected with the electrodes; the air outlet end is an insulating high-temperature-resistant pipe, or the air outlet end is connected with the insulating high-temperature-resistant pipe, and the electrodes are arranged in the insulating high-temperature-resistant pipe; and the water containing space is communicated with the sealed cavity, and plasma gas in the sealed cavity is continuously injected into or blown into deionized water. The device is simple in structure, gas circularly flows in the insulating high-temperature-resistant pipe and is subjected to repeated sliding arc discharge ionization, and formed plasma gas with relatively high concentration is dissolved into deionized water to form activated sterilization water.

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 water by air plasma. Background technique [0002] Atmospheric plasma technology is a new type of sterilization technology, which has a wide range of applications in the field of sterilization and disinfection. Based on different plasma generation modes, this technology has many sterilizing forms, which is a hotspot in the field of current research and application. [0003] Plasma gas is a new type of non-residue green sterilization technology, and the sterilization effect varies greatly with the different plasma discharge generation modes. [0004] At present, the main component of dielectric barrier discharge sterilization is ozone ions and the sterilization space is small, limited to the discharge area and the sterilization gas is harmful to the human body. The sliding arc discharge in industrial ...
