Description

HPAE with hydrogen peroxide solution injection drive signal control device

The present invention relates to a Hydrogen Peroxide Aerosol Equipment (HPAE), and more particularly, to a method of controlling the amount of hydrogen peroxide aerosol (HPA) or ionized hydrogen peroxide aerosol (IHPA) sprayed in a dry form to prevent excessive condensation of HPA or IHPA The present invention relates to an HPAE equipped with a hydrogen peroxide solution injection drive signal control device.

Generally, there is a need to establish a sterilization and manufacturing facility for biological safety, food and pharmaceuticals such as laboratories, animal breeding facilities, Good Manufacturing Practice (GMP), biological safety level (BSL-3 grade, Biological Safety Level-3) Internal laboratory and production rooms require clean, sterile management. Unlike cleaning or disinfection, this sterilization means a high level of treatment in that it means completely eliminating all living microorganisms through physical and chemical action. Currently, EO (ethylene oxide) gas, steam, hydrogen peroxide, and plasma are used as the sterilization method.

It has been reported that sterilization using EO gas, by itself, has a high risk of explosion and acts as a genotoxic substance causing mutation. Steam sterilizers are considered to be one of the safest ways to meet sterilization power to a certain level. The steam sterilizer is advantageous in that it is not toxic, its price is comparatively cheap, and it is possible to sterilize quickly. However, it is disadvantageous in that it can be used only in a medical apparatus which has no side effects even when exposed to moisture and high temperature. Hydrogen peroxide, ozone, and a plasma generator are appropriately used in combination. For example, there are a method of supplying hydrogen peroxide to the sterilization chamber and generating sterilization by generating plasma in the sterilization chamber, a method of simultaneously supplying plasma and sterilant to the sterilization chamber, a method of generating plasma in a state where oxygen is supplied to the sterilization chamber A method in which sterilization is performed by converting into ozone, and a method in which hydrogen peroxide and ozone are supplied together to sterilize a subject to be sterilized in a sterilization chamber.

That is, conventional sterilization apparatuses using hydrogen peroxide and plasma inhibit the entry and exit of living bodies such as humans into a specific space for sterilization, and after the sterilization space is sealed, ionized hydrogen peroxide aerosol (IHPA) is injected. Then, the ionized hydrogen peroxide aerosol injection is stopped, and the sterilizing of the specific space is performed by waiting for a predetermined time. Thereafter, hydrogen peroxide is removed using a specific air conditioning system or an aeration device of a gas scrubber. That is, conventionally, in order to maintain the concentration of hydrogen peroxide in the sterilization space at a specific value or higher (for example, exposure of more than 150 ppm at a concentration of 150 ppm or more), HPA or IHPA is sprayed to increase the concentration, There is a problem that side effects such as changes in physical properties and corrosion due to the development occur. Korean Patent Publication No. 10-0782040 discloses a sterilization method using hydrogen peroxide and ozone, and an apparatus according to the method, in the prior art.

The present invention has been proposed in order to solve the above-mentioned problems of the previously proposed methods, and it has been proposed to control the injection amount of hydrogen peroxide aerosol (HPA) sprayed in dry form or hydrogen peroxide aerosol (IHPA) The hydrogen peroxide solution injection drive signal control device controls the operation of the mist generating device and the plasma generating device so that the HPA (hydrogen peroxide solution injection drive signal) Or an IHPA injection amount is controlled so that the condensation phenomenon due to excessive HPA or IHPA can be prevented by minimizing the HPAE with the hydrogen peroxide solution injection drive signal control device.
