Background

Hydrogen peroxide of the formula H₂O₂The water solution is commonly called as hydrogen peroxide, is colorless and transparent liquid in appearance, is a strong oxidant, and is suitable for wound disinfection and environment and food disinfection.

Vaporized hydrogen peroxide is a vapor formed by heating 35% hydrogen peroxide liquid to 130 c, and vapor phase hydrogen peroxide is diffused in the space. The vaporized hydrogen peroxide can achieve 6-log killing rate of bacterial spores, including clostridium difficile and other common hospital bacteria, such as MRSA, VRE, Acinetobacter baumannii and viruses.

At present, the apparatus for vaporizing hydrogen peroxide is mainly a drop-type vaporizer (i.e., a peristaltic pump is used to titrate a small amount of mixed solution of hydrogen peroxide and water onto a heating surface to form hydrogen peroxide gas, and air is guided over the heating surface to take out the vaporized hydrogen peroxide gas, as shown in fig. 1.

Such a device suffers from the following disadvantages: 1. the drip-type hydrogen peroxide sterilizer has a certain injection rate limit, and a single liquid drop cannot be maintained at a higher rate; 2. when the hydrogen peroxide solution is titrated on the heating panel, the dripping type vaporizer has great influence on the temperature of the heating panel, and the cooling of the heating panel is easy to cause that the stability of the gasification effect cannot be ensured; 3. the strong oxidizing solution is titrated on a stainless steel plate for a long time, and a layer of passive film is easily formed on the stainless steel plate, so that the later vaporization effect is weakened.
