Description

Microwave disinfection and sterilization device

Technical Field

The utility model belongs to the technical field of air purification, concretely relates to microwave disinfection and isolation device.

Background

The knowledge of disinfection and sterilization has been only in disinfection and sterilization of indoor objects, materials, even body parts and other surfaces, and the disinfection and sterilization method generally comprises spraying special chemicals, high-pressure sterilization or high-temperature sterilization, and is also important for disinfection and sterilization of air in an activity space. Bioaerosols are biological components in the air, and generally refer to aerosols containing microorganisms and other components with an aerodynamic diameter of 100 μm, mainly including bacteria, viruses, fungi and their debris and secretions, pollen, and various mycotoxins, etc. (volleyball, 1997; Nayar et al, 2011). Biological components in the air, particularly bacteria, fungi and viruses, once they contact human tissues (or organs) through respiration, can multiply in large quantities, causing a variety of health problems including lung disease, adverse acute reactions, and sick building syndrome. In recent years, large-scale influenza epidemics caused by virus spread (such as H1N1 and SARS virus) frequently occur in closed and semi-closed spaces, and how to effectively sterilize indoor air is not slow.

At present, aiming at removing pathogenic sources such as bacteria and viruses, the ozone purification technology and the plasma purification technology are adopted in the market more advanced, but ozone can stimulate respiratory mucosa of a human body to cause asthma and shortness of breath, and researches show that the risk of suffering from upper respiratory tract infection is increased by 4 percent (Darrow et al, 2014) when the mean value of an ozone 3 balance is increased by 30ppb every time, and the plasma purification technology can generate secondary pollution of ozone, so that the ozone purification technology is a pain point in the air purification industry all the time. There are also products that remove ozone by terminal heating, but the corresponding high energy consumption is still unavoidable. The microwave technology can directly act on the cell membrane of bacteria, reduce the permeability of cells, destroy the balance of substances inside and outside the cells, and change the membrane potential and the polar molecular structure of the cell by a high-frequency electric field to cause the loss of biological activity. Further, the microwave energy can directly act on the proteins of the microorganisms and physiologically active substances such as DNA and RNA to cause mutation and lose activity or death. Meanwhile, the method has the characteristics of rapidness, thoroughness, green broad spectrum and no by-product, and is reported to be used for removing bacterial viruses in the ambient air by a plurality of patents.

Although the prior art can realize disinfection and sterilization to a certain extent, the introduction of water vapor causes a user to add a stock solution periodically, so that the use operation is complicated. The introduction of the microwave excitation ultraviolet light for disinfection and sterilization causes ozone pollution on one hand, and also causes the improvement of equipment cost on the other hand, and meanwhile, the regular replacement of the light source also causes the improvement of the use cost of users. Meanwhile, the single microwave source causes the sterilization effect to be not remarkable.
