Method and device for detoxifying and deodorizing sterilizing gas

Abstract

A device for detoxifying and deodorizing a sterilizing gas, which includes a main pipe line functioning at one end thereof as a sterilizing gas inlet and at the other end thereof as a treated gas outlet, a blower connected to the inlet side at the middle of the main pipe line, a preheater, an oxidizing / decomposing means and a cooling means that are sequentially connected from the blower toward the outlet, and a bypass pipe line provided for that portion of the main pipe line where devices starting with the blower and including the cooling means are installed, is connected to a sterilizing tank, a sterilizing device is operated for a preset time for sterilizing, the device for detoxifying and deodorizing the sterilizing gas is operated a little ahead of the end of the sterilizing process to idling-circulate the gas for a preset time between the main and bypass pipe lines, the gas is then circulated between the sterilizing tank and the main pipe line for detoxifying, and a neutralizer is then introduced into the sterilizing tank for later treating by repeating the same steps as when the sterilizer was treated.

Description

technical field [0001] The invention relates to a method and device for purifying disinfection gas, and in particular to a harmless and deodorizing method and device for disinfection gas. Background technique [0002] Nowadays, the methods of disinfection employed in medical facilities are based on the disinfection of items using autoclave steam sterilizers, gas sterilizers or ultraviolet sterilizers, especially due to the economical and strong sterilizing power of formalin sterilizers for liquid drugs, The most widely used. In some other sterilizers, the ammonia system is generally used as a neutralization or elimination method for formaldehyde gas generated by formalin gas, but it is difficult to achieve complete elimination using this method. Therefore, incompletely neutralized formaldehyde gas, ammonia gas, etc. are discharged from the sterilization chamber to the atmosphere through the exhaust pipe (for example, Japanese Patent Laid-Open No. 1996-057027).

AI Technical Summary

Problems solved by technology

[0003] Although the use of formalin disinfection has many advantages, it also has a big disadvantage

Formaldehyde has a particularly strong pungent smell. If this smell remains in the disinfected items as residual gas, disinfection workers or hospitalized patients may be exposed to formaldehyde gas, which is very harmful to health.

The release of this gas into the atmosphere will pose a serious threat to environmental protection
