Description

Dry fog sterilizing machine

Technical Field

The invention relates to a dry fog sterilizer.

Background

Because the influence of epidemic situation at present, most activity spaces all need carry out the disinfection and sterilization processing, and the disinfection and sterilization all adopt the disinfectant to carry out at present, and sterilizing equipment among the prior art all has certain limitation.

For example, the following are the traditional hydrogen peroxide disinfection methods currently on the market:

1. the hydrogen peroxide is vaporized to realize disinfection, the generation mode and the action form of the hydrogen peroxide belong to the category of steam, and the principle lies in that the hydrogen peroxide steam is utilized to sterilize microorganisms in the condensation process. The concentration of hydrogen peroxide adopted by vaporized hydrogen peroxide is about 30%, flash evaporation is carried out at 114 ℃ through an electric heating mode, then steam is formed at about 60 ℃, and the two action modes of dry method and wet method are divided afterwards to form a layer of 2-6 micron film as a purpose.

2. The air source type atomized hydrogen peroxide atomizes the compound disinfectant of hydrogen peroxide and peroxyacetic acid by using 0.3-0.35MPa of compressed air, and the core accessory is a spray head which can form the disinfectant into tiny particles. The core component of the sterilization mode is a spray head, the quality of the spray head directly determines the size of the mist particles, and the size of the mist particles determines the diffusion effect of the disinfectant. Because of the uneven quality of current domestic spray heads, the actual misting of many devices is substantially visible to the naked eye, i.e., at least 40-50 microns, rather than factory-advertised dry mists, which must be less than 10 microns in size, with particles of less than 10 microns being invisible to the naked eye. Because the structure of the spray head is relatively complex, the requirement on the atomizing spray head is high, the cost is relatively high, the atomized particles are large, the diffusion is not uniform, the sterilization effect is relatively poor, and meanwhile, the obvious corrosion can be caused.

3. The dry fog type compressed hydrogen peroxide gas tank is characterized in that compressed air is filled into a hydrogen peroxide disinfectant tank, the atomization amount is controlled by adjusting a valve opening of the liquid tank, dry fog particles smaller than 10 micrometers are formed, the dry fog type compressed hydrogen gas tank is relatively high in cost, and a pressurized hydrogen peroxide gas tank is used for supplying liquid, so that higher use risk exists.

4. Hydrogen peroxide is sterilized by ionization to bring it into an ionized state, and this method cannot be used in a wide range because of its small range of action space and high price.
