Technical Field

The invention relates to the technical field of air disinfection and purification, in particular to a positive and negative corona type plasma reactor for an air disinfector.

Background

The plasma air sterilizer (purifier) is widely used in hospitals, food processing factories and schools, and mainly comprises a casing, a fan assembly, a plasma reactor, a control circuit and a filter screen. The fan assembly, the plasma reactor, the control circuit and the filter screen are all installed in the casing, and an air inlet and an air outlet are designed on the casing. Through fan assembly's centrifugal force, make the air pass through the air intake, filter debris such as dust, granule through the filter screen, disinfect disinfection and dust removal purification treatment by the plasma reactor again, the air is seen off through the air outlet after the processing, and above process is carried out many times repeatedly to realize disinfecting (purifying) function, the plasma reactor is the core component in plasma air disinfection (purification) ware, comprises positive electrode and negative plate and mounting panel, its principle of disinfecting: 1. function of the active group: the plasma contains a large number of active ions, high-energy free radicals and other components, which are easy to chemically react with proteins and nucleic acids in bacteria, molds, spores and viruses, and can destroy microorganisms and disturb the survival function of the microorganisms, so that various microorganisms die; 2. high-speed particle breakdown: after a sterilization experiment, images of bacterial thalli and virus particles after plasma action are observed through an electron microscope, and the images are all in a scabby hole shape, which is caused by a breakdown etching effect generated by electrons and ions with high kinetic energy; 3. the electrostatic adsorption function: capturing dust, virus and other tiny particles, and adsorbing the particles on the negative plate. The existing plasma discharge modes for air disinfection (purification) are two, one is a positive electrode plus positive voltage mode, and the other is a negative electrode plus negative voltage mode, namely a positive corona mode; the other is a negative corona mode that a positive electrode is added with a negative voltage, and a negative electrode plate is added with a positive voltage; the positive corona mode can observe that obvious electric arcs are generated between the positive pole and the negative pole in a darkroom, and the sterilization mechanism of the positive corona mode is mainly as follows: the action of active groups and the breakdown action of high-speed particles are weak in electrostatic adsorption, the dust removal effect is not ideal, the negative corona mode can be observed in a dark room, and only the positive electrode can have corona light, and the sterilization mechanism is mainly as follows: the effect of active groups and the effect of electrostatic adsorption are weak in high-speed particle breakdown effect, and the dust removal effect is good in the mode.

The existing products adopt one of the two modes, and from experimental results, the disinfection effect cannot reach the limit value specified by the industry within the specified disinfection time only by the single mode of plasma disinfection, the requirement can be met only by combining a primary-effect filter screen or prolonging the disinfection time of a machine, and the reason for analyzing the requirement is caused by the low disposable sterilization effect of the plasma in the mode. The industry has specific regulations on the disinfection time, so the scheme of prolonging the disinfection time is not feasible. The plasma is combined with a primary filter screen or a medium-efficiency filter screen to sterilize, and can reach the industrial regulation within the regulated time. But has the following disadvantages: 1. the primary filter screen or the medium-high efficiency filter screen needs to be frequently replaced, so that the use and maintenance cost of a user is increased; 2. the wind resistance of the primary-effect filter screen or the medium-high-efficiency filter screen is larger, the longer the service life is, the larger the wind resistance is, the circulating air quantity of the machine is greatly weakened, and the disinfection effect is seriously influenced.
