Problems solved by technology

The traditional analysis room and precipitation method only use two conditions of heating and exhaust. Ethylene oxide is passively and naturally precipitated, and the precipitation efficiency is low. It takes a long time for the precipitation to fall below the qualified line, resulting in a relatively low utilization rate of the analysis room. Low

Abstract

The invention relates to an ethylene oxide precipitation method, in particular to an ethylene oxide rapid precipitation system and method. The device comprises a container and a heating device used for heating an inner cavity of the container. The wall of the container is provided with an opening convenient for products to go in and out. The container is characterized in that a sealing door is arranged on the opening, and the inner cavity of the container is a sealed cavity when the sealing door is in a closed state. And the container is connected with a vacuumizing device and an air inlet device. And a pressure gauge and a thermometer are arranged on the container. The precipitation method comprises the following steps: 1) putting a product into a container, and keeping the temperature of the container at a set temperature; 2) carrying out vacuum pumping, primary pressure maintaining, air inlet and secondary pressure maintaining on the container; 3) repeating the step 2); (4) convection is conducted; and (5) repeating the step (2) to the step (4) for n times. By adopting the system and the method, the efficiency of separating out ethylene oxide is relatively high, the time consumed for separating out ethylene oxide below a qualified line is relatively short, and the utilization rate of the analysis room is relatively high.

Description

technical field [0001] The invention relates to an ethylene oxide precipitation method, in particular to an ethylene oxide rapid precipitation system and method which can improve the ethylene oxide precipitation efficiency. Background technique [0002] Ethylene oxide (EO) is the simplest cyclic ether, which belongs to heterocyclic compounds and is an important petrochemical product. Ethylene oxide is the second-generation chemical disinfectant after formaldehyde, and it is still one of the best cold disinfectants. It can be used to disinfect some products and materials that cannot withstand high-temperature disinfection, such as commonly used in the medical industry. Sterile towels. Ethylene oxide is a carcinogen. After using it to sterilize sterile towels and other products that are in direct or indirect contact with the human body, the residual ethylene oxide in the product needs to be separated out. [0003] At present, the traditional analytical room is used in the in...
