Description

A kind of ozone room temperature sterilization box

technical field

The utility model specifically relates to an ozone room temperature sterilization box.

Background technique

Sterilization cabinets are widely used in sterilization workshops in pharmaceutical, food processing, biological products, medical and health industries. Sterilization cabinets mainly include high-temperature sterilization cabinets and low-temperature sterilization cabinets. High-temperature sterilization cabinets use high-temperature and high-pressure steam to sterilize items that can withstand high temperatures under high-temperature conditions, while low-temperature sterilization cabinets use low-temperature peroxidation Hydrogen sterilizes items that cannot withstand high temperatures under low temperature conditions.

The chemical formula of hydrogen peroxide is H2O2. Pure hydrogen peroxide is a light blue viscous liquid that can be mixed with water in any proportion. It is a strong oxidant. The aqueous solution is commonly known as hydrogen peroxide and is a colorless transparent liquid. Hydrogen peroxide aqueous solution is suitable for medical wound disinfection, environmental disinfection and food disinfection. Under normal circumstances, it will decompose into water and oxygen, but the decomposition speed is extremely slow. The way to speed up its reaction speed is to add catalyst manganese dioxide or irradiate with short-wave radiation .

Existing low-temperature sterilizers use low-temperature hydrogen peroxide to sterilize items that cannot withstand high temperatures. Hydrogen peroxide needs to be purchased externally. The disinfection process requires a lot of hydrogen peroxide solution, and most of the hydrogen peroxide solution is wasted. It is wasteful to use again, use Chen Bengao. The used hydrogen peroxide solution is highly polluting, and direct discharge will cause serious pollution to the natural environment.

There are walking wheels below.

Preferably, the storage rack cart is made of stainless steel pipes.

The beneficial effects of the utility model are:

1. The exhaust fan of the utility model draws out the air in the inner casing and then closes it. The ozone generated by the ozone machine is discharged into the inner casing through the air distribution pipe to sterilize the articles. The ozone can sterilize the articles under normal temperature conditions. Will not cause damage to items that cannot withstand high temperatures. After the disinfection is completed, the exhaust fan is started to extract the ozone in the inner shell, and the extracted ozone is mixed with normal air so that the ozone concentration does not exceed 0.2mg/ ^m3 and can be discharged without causing harm to the natural environment. The processing process is simple and convenient Will produce pollution.

2. There are a plurality of porous shelf boards evenly distributed from top to bottom in the storage rack car of the present invention. There are many support members welded on the inside of the storage rack car to support the porous shelf boards. wheel. The porous shelf plate in the storage rack car 6 can be partially taken out to adjust the spacing between adjacent porous shelf plates, so as to facilitate putting in articles of different sizes.
