Preparation method of high-purity chlorine dioxide gas

Abstract

The invention discloses a preparation method and a special device of high-purity chlorine dioxide gas. The preparation method comprises the following steps of: conveying compressed air into a gasifier (10) through a gas distributor (8) and controlling the distribution ratio of the compressed air at the lower part and the upper part of the gasifier (10); and carrying out gasification reaction between stable chlorine dioxide solution and diluted hydrochloric acid in the gasifier (10) to obtain the high-purity chlorine dioxide gas. The method takes the stable chlorine dioxide solution as a disinfectant and adopts the special device to prepare the high-purity chlorine dioxide gas, the gas purity is improved by 100 percent from current 80 percent, and simultaneously, the medicine liquid utilization ratio is improved, the emission is reduced, and the yield of the product is also remarkably improved. The method can convey the produced high-purity chlorine dioxide gas into a required space rapidly, timely and quantitatively for air sterilization, thereby not only improving the security and realizing the safety sterilization, but also being capable of achieving better disinfection and sterilization effect.

Description

technical field [0001] The invention relates to a method for preparing high-purity chlorine dioxide gas, and also relates to a special device for realizing the preparation method, which belongs to the field of preparation of disinfectants. Background technique [0002] In recent years, because chlorine dioxide has the advantages of rapid sterilization, good sterilization effect, no residue, and no side effects, it has been more and more recognized by people. At present, it has gradually expanded from a wide range of water disinfection fields to air disinfection fields. [0003] In the field of air disinfection using chlorine dioxide, it has now developed from the initial simple use methods such as spraying, spraying, or natural volatilization to chlorine dioxide air disinfection machines. However, for the original air sterilizer, although great progress has been made, there are still some defects, mainly, the gasification process is cumbersome, the equipment is many, not com...

AI Technical Summary

Problems solved by technology

However, for the original air sterilizer, although great progress has been made, there are still some defects, mainly, the gasification process is cumbersome, the equipment is many, not compact, the gasification technology is simple, the equipment structure is unreasonable, and the gasification The purity of chlorine dioxide gas is low, chlorine gas is produced, the utilization rate of the liquid medicine is low, and the level of automatic control is low. Especially in the implementation of air disinfection, there are certain unsafe factors, especially in the case of people, people will feel uncomfortable. I feel that under the same disinfection effect, compared with the new technology, it has poor safety, large volume and high raw material consumption

At present, there is no method and special device for preparing high-purity chlorine dioxide gas by using the automatic control gas distribution positive pressure gasification technology in China
