Purification system

Abstract

A hydrogen peroxide mist supplied to a chamber to be purified is further refined and dispersed / diffused, and a perfect purification effect is achieved by supplying an appropriate amount of hydrogen peroxide mist to the chamber to be purified, and the efficiency of purification work is achieved by shortening the working time of ventilation and the like. A purification system is provided with a mist generation means, a mist discharge port, and a mist dispersion / diffusion means. The mist generating unit generates mist for purification by atomizing the purification liquid. The mist discharge port opens at the upper part of the inner side wall surface of the chamber to be purified and discharges purification mist into the chamber to be purified. The mist dispersing / diffusing means generates an acoustic flow by ultrasonic waves in the vertical direction from a disk surface of a vibrating disk disposed in the vicinity of the lower part of a mist discharge port in the inner side wall surface of the chamber to be purified or in the vicinity of the lower part of the side wall surface in the mist discharge direction, and intermittently operates or weakly operates a pressing force generated by acoustic radiation pressure on the purification mist from the rear or the side surface.

Description

technical field [0001] The present invention relates to a purification system for generating and purifying indoors such as isolators, RABSs, sterile rooms, and passage rooms, passage compartments, etc., which are attached thereto, for purification. Background technique [0002] It is important to maintain the sterile state of the room at a manufacturing site where drugs, food, etc. are manufactured, or a medical site such as an operating room. In particular, in the purification of a sterile room, which is a workroom for pharmaceutical manufacturing, it is necessary to complete a high level of purification verification conforming to GMP (Good Manufacturing Practice: Production Quality Control Standards). [0003] In recent years, hydrogen peroxide gas has been widely used for purification of a workroom (hereinafter referred to as a purification target room) requiring a sterile environment. The hydrogen peroxide gas has a high sterilization effect, is inexpensive and readily ...

AI Technical Summary

Problems solved by technology

However, when an excessive amount of hydrogen peroxide gas is supplied, there is a problem that it takes a lot of time to ventilate to remove the condensed film of the high-concentration hydrogen peroxide liquid generated on the wall surface of the purification target chamber, etc.

[0006] On the other hand, when the amount of hydrogen peroxide gas supplied to the room to be cleaned is small, the condensation becomes insufficient, and there is a problem that a sufficient cleaning effect cannot be obtained.
