Problems solved by technology

Common atomization disinfection methods include ultrasonic atomization, two-fluid atomization and steam atomization, etc. The particles of the two-fluid atomization are generally large, between 7-20 microns, and the atomized particles are large and uneven. When it is below 5 microns, its atomization efficiency will be very low
The atomized particles of traditional ultrasonic atomization disinfection equipment can be between 3-5 microns, but the atomized particles are still relatively large, which will lead to high humidity in the disinfection space, which is not

Embodiment 1

[0088] Reduce the concentration of disinfectant under the same sterilization rate: hydrogen peroxide solution. The hydrogen peroxide solution of 1% concentration is passed through the device of the present invention to generate 100 nanometers of hydrogen peroxide aerosol, compared with the hydrogen peroxide solution of 10-20% concentration being atomized into a liquid mist of 5-10 microns, it has the same Air sterilization rate, that is, under the same air sterilization rate, using the equipment of the present invention, the concentration of hydrogen peroxide used can be reduced by 10-20 times compared with traditional atomization disinfection devices.

Embodiment 2

[0090] Under the same amount of disinfectant used, a higher effective concentration of disinfectant (higher sterilization rate) is obtained: slightly acidic hypochlorous acid solution. Use the slightly acidic hypochlorous acid solution of available chlorine 200mg / L, pH value 6.0, disinfectant consumption rate 100ml / hour, use the equipment of the present invention to measure the available chlorine content of hypochlorous acid aerosol at distance from liquid mist nozzle 100mm place about The effective chlorine content of the hypochlorous acid mist measured at 100mm from the mist outlet using an ordinary ultrasonic atomization disinfection machine is less than 5mg / L. That is, at the same consumption rate of hypochlorous acid disinfectant, the available chlorine content of the hypochlorous acid aerosol sent by the equipment of the present invention is more than 10 times higher than that of the traditional ultrasonic atomization disinfection machine.

Abstract

The invention relates to the field of disinfection of air and object surfaces, in particular to nanometer aerosol disinfection equipment capable of converting a disinfectant into nanometer aerosol. The nanometer aerosol disinfection equipment comprises an atomization device, a screening device and a distribution device, wherein the atomization device is used for generating aerosol spray; the screening device communicates with the atomization device, and a barrier part capable of forming a carrier gas flow path, which extends crookedly, in the screening device is arranged in the screening device; and the distribution device comprises a spray chamber which communicates with the screening device, a gas flow chamber which is separated from the spray chamber, a co-gasification area which communicates with the spray chamber and the gas flow chamber, and a spray nozzle which communicates with the co-gasification area. The provided nanometer aerosol disinfection equipment can effectively convert the disinfectant into the nanometer aerosol spray without equipment of heating device and the like so that the nanometer aerosol spray can be used for disinfection operation.

Description

technical field [0001] The invention relates to the field of air and object surface disinfection, in particular to nano-aerosol disinfection equipment for converting disinfectant into nano-scale aerosol. Background technique [0002] Atomization disinfection technology is a technology that decomposes liquid disinfectants into fine droplets and sends them into the air or the surface of objects to achieve disinfection. Common atomization disinfection methods include ultrasonic atomization, two-fluid atomization and steam atomization, etc. The particles of the two-fluid atomization are generally large, between 7-20 microns, and the atomized particles are large and uneven. When it is below 5 microns, the atomization efficiency will be very low. The atomized particles of traditional ultrasonic atomization disinfection equipment can be between 3-5 microns, but the atomized particles are still relatively large, which will lead to high humidity in the disinfection space, which is n...
