Abstract

The present invention belongs to the field of sterilization apparatuses and sterilization methods, and particularly relates to a hydrogen peroxide sterilization apparatus and a hydrogen peroxide sterilization method. With the hydrogen peroxide sterilization apparatus and the hydrogen peroxide sterilization method, vaporized hydrogen peroxide can be produced so as to effectively sterilize the space and the object requiring sterilization, and the hydrogen peroxide residue can be rapidly cleared after the sterilization is completed. The hydrogen peroxide sterilization apparatus of the present invention comprises a liquid storage container, a peristaltic pump, a vaporizer, a heating device, a temperature sensor, a sterilization gas inlet valve, a sterilization space, and a related control system.

Description

technical field [0001] The invention belongs to the field of sterilization equipment and sterilization methods, and in particular relates to a hydrogen peroxide sterilization device and method. Background technique [0002] At present, in the pharmaceutical, food, and precision electronics industries, the production, assembly, and inspection of certain items need to be carried out in a sterile environment, so it is necessary to sterilize and disinfect the space where these items are produced and the items themselves. With the development of production technology, the original sterilization methods such as ultraviolet, ozone, and formaldehyde are becoming less and less popular because of their low sterilization efficiency, difficulty in verification, high corrosion, and toxic residues. accept. [0003] The sterilizing performance of hydrogen peroxide has been accumulated through more than 100 years of experience, and its sporicidal ability has been confirmed by many parties....
