Plasma enhanced paper money disinfection sterilizer and method

Abstract

The present invention discloses a plasma enhanced paper money disinfection sterilizer and a method. The plasma enhanced paper money disinfection sterilizer comprises a sterilization chamber body, wherein a plurality of drawers capable of holding paper money are placed in the sterilization chamber body in a parallel manner, an ultraviolet lamp is hung just above the drawer, plasma generators are arranged on both sides of the drawer, and comprise high-voltage electrodes and ground electrodes, the high-voltage electrodes and the ground electrodes are arranged in a cross manner, and are connected to the positive electrode and the negative electrode of a plasma power supply placed outside the sterilization chamber body respectively through conducting wires, the side wall of the sterilization chamber body is provided with a fan, the sterilization chamber body is provided with a gas inlet hole and a gas exhaust hole, the gas inlet hole is sequentially connected with a gas inlet valve, a dehumidifier and a filter through pipelines, and the gas exhaust hole is connected with a vacuum pump through a pipeline. According to the present invention, the efficient microorganism killing effect is achieved through production of the low pressure and atmospheric pressure plasmas and the synergistic ultraviolet sterilization effect so as to achieve disinfection sterilization of bundles of paper money.

Description

technical field [0001] The invention relates to a device and method for disinfecting banknotes by using plasma technology, and belongs to the technical field of low-temperature plasma application and disinfection. Background technique [0002] In the process of circulation, banknotes are easily polluted after being touched by countless hands. In addition to the obvious dirt that we can easily see, the surface of banknotes also carries a large number of microorganisms. According to health inspections, there are more than 26,000 to 69,000 pathogenic microorganisms on each banknote, and the maximum number can reach more than 300,000. This has become an important way for disease transmission and seriously endangers people's health. [0003] Traditional physical and chemical sterilization methods, such as ozone disinfection, ultraviolet sterilization, etc., have various problems. The penetration of ultraviolet light is limited, and the damage of long-term high-concentration ozon...

AI Technical Summary

Problems solved by technology

However, due to the poor penetration of plasma, the existing plasma banknote sterilization technology can only achieve effective sterilization of single banknotes, and the sterilization effect on stacked banknotes is poor.
