Room-temperature vaporizing and sterilizing system

Abstract

The invention discloses a room-temperature vaporizing and sterilizing system. The room-temperature vaporizing and sterilizing system comprises a liquid storage system stored with disinfectant, a atomizing separation system for atomizing the disinfectant, a drive system for providing power for the atomizing separation system and a vaporizing separation system for separating and vaporizing the atomized disinfectant, wherein the drive system is sequentially connected with the atomizing separation system and the vaporizing separation system, the liquid storage system is connected with the atomizing separation system and the vaporizing separation system, and the liquid storage system is used for providing the disinfectant for the atomizing separation system and used for recycling the disinfectant collected by the vaporizing separation system and the atomizing separation system. The room-temperature vaporizing and sterilizing system has the advantages that the produced disinfectant is small in particle, most of the particles of the disinfectant can reach the sizes of bacteria or be smaller than the sizes of the bacteria, and the disinfectant particles can be suspended in the air for a long time and sufficiently contact with the bacteria to kill the bacteria.

Description

technical field [0001] The application relates to the field of sanitation and disinfection, in particular to a room temperature vaporization disinfection and sterilization system. Background technique [0002] Hydrogen peroxide (H 2 o 2 ) used as a disinfectant has many advantages. After killing bacteria, the decomposition products are water and oxygen without any poisonous and stimulating effects, and will not form secondary pollution. It is a relatively ideal disinfection product. In particular, hydrogen peroxide in the vapor state has a stronger ability to kill bacteria than in the liquid state. Therefore, the use of vapor hydrogen peroxide for disinfection and sterilization has attracted more and more attention. ), the methods recommended by the technical specifications for disinfection and sterilization. [0003] Currently used vaporized hydrogen peroxide sterilization technology and equipment mainly utilize flash technology: that is, a high-concentration hydrogen pe...

AI Technical Summary

Problems solved by technology

The main problem that this technology exists is: 1) needs to use the hydrogen peroxide solution of high concentration (concentration is greater than 30%) to carry out vaporization under high temperature condition, causes the decomposition and corrosion problem of a large amount of hydrogen peroxide inevitably like this, thus Material compatibility is poor; 2) This technology and equipment are aimed at different room sizes, and the concentration parameters of hydrogen peroxide are difficult to control; 3) The pipeline for transporting hydrogen peroxide vapor starts from the outlet of the generator to the end of the diffuser. The road must be kept above 60°C, otherwise condensation will occur due to the decrease in the temperature of the hydrogen peroxide vapor; 4) The air humidity requirements for the disinfection and sterilization space are very strict, generally requiring RH to be below 40% or even 20%

[0004] In order to solve the problem of decomposition caused by too large particles (2-6 microns) and too high temperature (about 130 degrees) of the existing vaporized hydrogen peroxide flash technology, patents CN101237894A and CN104984378A disclose an ultrasonic atomization-separation technology: first Use ultrasonic atomization technology to atomize the disinfectant into particles of a certain size (10-100 microns), and then use the gravity of atomized particles of different sizes to separate the particles of different sizes, and then use the heating unit to peroxidize the small particles Hydrogen disinfectant for heating and vaporization

The main problems of this technology are: 1) still need to use high-concentration hydrogen peroxide; Condensation problem, 3) This method is only suitable for vaporizing small particles (10-100 microns) of disinfectant atomized by ultrasonic atomization technology, and is not suitable for vaporizing particles atomized by other atomization technologies, so the compatibility is not good ideal

Although this method does not need to use high-concentration hydrogen peroxide, there are still the following problems: 1) still need to use hot air to vaporize; A good separation and vaporization effect must use multiple cavity structures, so it is bulky; 3) It is not suitable for vaporizing particles produced by other atomization technologies, and the compatibility is not ideal
