Embodiment 1

[0033] Such as figure 1 and figure 2 As shown, a VHP sterilization generator disclosed by the present invention includes a flash chamber 1 and a sterilization chamber 2, and the internal channel of the flash chamber 1 is filled with several evenly distributed beads 9, and the beads 9 are made of steel , the pipeline of the flash chamber 1 is connected with the atomizer 3, and one end of the atomizer 3 is connected with the compressed air supply device 41 and the hydrogen peroxide container 51 respectively, and a peristaltic device is arranged between the hydrogen peroxide container 51 and the atomizer 3 A filter device 42 for purification is installed between the pump 52 , the compressed air supply device 41 and the atomizer 3 , and a pressure reducer is installed between the filter device 42 and the compressed air supply device 41 .

[0034] The pipeline of the flash chamber 1 is connected with a heater 7, and the pipeline of the heater 7 is connected with a blower 6 for ex...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that: figure 2 and image 3 As shown, a temperature-adjusting heat exchanger 10 is installed between the heater 7 and the flash chamber 1, and a regulating valve is provided in front of the heat exchanger 10, and the regulating valve is provided with a first valve end 101 and a second valve end 102 respectively. The regulating valve realizes the temperature regulation of the output gas by controlling the flow between the first valve end 101 and the second valve end 102, and the other end of the flash chamber 1 is respectively connected with a temperature sensor, a humidity sensor and a concentration sensor.

[0040] The operating conditions and principles of this embodiment are as follows:

[0041] When sterilization is required, the air blower 6 draws air from the outside and transports it to the heater 7. The heater 7 heats the air to 360°C to form sterile high-temperature air. The sterile high-temperature a...

Abstract

The invention relates to a VHP sterilization generator. The VHP sterilization generator comprises a flash chamber and an atomizer, wherein a plurality of uniformly distributed beads are arranged in an internal channel of the flash chamber, one end of the flash chamber is connected with the atomizer, and one end of the atomizer is separately connected with a compressed air supply device and a hydrogen peroxide container. By adopting the technical scheme, hydrogen peroxide is gasified more thoroughly, and the killing efficiency of the system is increased.

Description

technical field [0001] The invention relates to the technical field of sterilization equipment, in particular to a VHP sterilization generator. Background technique [0002] The traditional clean room air sterilization technology mainly uses ozone or formaldehyde for disinfection or sterilization. With the development of sterile drug production, the requirements for production environment, safety and environmental protection are getting higher and higher, and the negative impact of formaldehyde fumigation is becoming more and more serious. The more attention is paid to it, and formaldehyde is easy to condense and adsorb during the disinfection process, resulting in a large amount of residue. People staying in an environment with formaldehyde residue for a long time will do great harm to human health, and the bactericidal effect is not ideal. [0003] The existing VHP sterilization system mainly uses hydrogen peroxide as the sterilization medium, which effectively improves th...
