Example Embodiment
[0027] Example 1
[0028] Using positive pressure gasification method, through the metering control system (metering pump 2 and metering pump 5), the concentration of 2.0% NaClO 2 The solution and hydrochloric acid with a concentration of 4% are added to the vaporizer 9 at a molar ratio of 1:3.87 to react, and the reaction temperature is controlled to 28°C. At the same time, compressed air is continuously delivered to the vaporizer through the air input device , Control the gas-liquid ratio to 18.5:1, the high-purity chlorine dioxide gas generated by gasification is carried out by the introduced compressed air and dilution air through the duct 12, and discharged to a volume of 103m 3 Air disinfection is carried out in a certain karaoke room (the separated waste liquid will be sent to the solution tank 7 regularly for centralized disposal and discharge). After 60 minutes of disinfection, samples were taken according to the following method: FA-1 impact air microbial sampler was use...

[0030] Example 2
[0031] Using positive pressure gasification method, through the metering control system (metering pump 2 and metering pump 5), the concentration of 2.5% NaClO 2 The solution and dilute hydrochloric acid with a concentration of 6% are added to the gasifier 9 at a molar ratio of 1:3.5 to react, and the reaction temperature is controlled to 26°C. At the same time, compressed air is continuously delivered to the gasifier through an air input device , The gas-liquid ratio is controlled to be 23.0:1, the high-purity chlorine dioxide gas generated by gasification is carried out by the introduced compressed air and dilution air through the duct 12, and discharged to a volume of 30m 3 Air disinfection was carried out in the employee dormitory of a certain factory (the separated waste liquid in the vaporizer was sent to the solution tank 7 regularly for centralized treatment and discharge), and the sample was sampled after 60 minutes of disinfection (the sampling method i...

[0033] Example 3
[0034] Using positive pressure gasification method, through the metering control system (metering pump 2 and metering pump 5), the NaClO concentration of 1.8% 2 The solution and hydrochloric acid with a concentration of 4% are added to the vaporizer 9 at a molar ratio of 1:3.93 to react, and the reaction temperature is 26°C. At the same time, compressed air is continuously delivered to the vaporizer through an air input device to control The gas-liquid ratio is 17.6:1. The high-purity chlorine dioxide gas generated by gasification is taken out through the duct 12 by the introduced compressed air and dilution air, and discharged to a volume of about 300m 3 Air disinfection was performed in the fever clinic of a certain hospital (the separated waste liquid in the vaporizer was sent to the solution tank 7 regularly for centralized treatment and discharge), and sampling was performed after 60 minutes of disinfection (the sampling method was the same as that in Examp...
