Embodiment 1
[0037] Such as figure 1 As shown, it is a schematic structural diagram of an ultrasonic sterilization device applied to a central air-conditioning ventilation system provided in this embodiment. The device includes an atomization unit, an adjustment unit, a blower 6, an air outlet duct 7, a return air duct 8 and a fresh air duct 1. The atomization unit includes an ultrasonic atomizer 11 connected to the disinfectant liquid storage tank 9; the adjustment unit includes a filter 2, a cooler 3 and a heater 4, the filter 2 is connected to the cooler 3, and the cooler 3 is connected to the heating device 4; the output end of the ultrasonic atomizer 11 and the output end of the heater 4 are respectively connected in parallel to the same delivery pipeline through pipelines and connected with the inlet of the blower 6, and the outlet of the blower 6 is connected to the air outlet duct 7, and the return air duct 8 and the fresh air pipe 1 are respectively connected to the input end of t...
Embodiment 2
[0041] Such as figure 2 As shown, it is a schematic diagram of an ultrasonic sterilization device applied to a central air-conditioning ventilation system provided in this embodiment, which is a further improvement on the basis of Embodiment 1, which also includes an airflow distributor 5, and the ultrasonic atomizer 11 outputs end and the output end of the heater 4 are respectively connected to the inlet end of the air distributor 5, and the outlet end of the air distributor 5 is connected to the air blower 6. The arrangement of the airflow distributor 5 can further realize the homogenization of the airflow from each path and improve the sterilization effect. An ultraviolet sterilizing lamp 12 is arranged between the air blower 6 and the air outlet duct 7 .
[0042] For the environment where the virus and bacteria in the building space are relatively harsh, the combination of chlorine dioxide disinfection and ultraviolet sterilization can be used to achieve safer disinfecti...
Embodiment 3
[0045] Such as image 3 As shown, it is a schematic diagram of an ultrasonic sterilization device applied to a central air-conditioning ventilation system provided by this embodiment, which is further improved on the basis of Embodiment 2, and a high-voltage electrostatic adsorber 13 is installed at the front end of the filter 2 . When viruses and bacteria in building spaces can be carried and transmitted by droplets, aerosols, and other particles, safe disinfection can be achieved by combining chlorine dioxide disinfection, ultraviolet sterilization, and high-voltage electrostatic adsorption. The high-voltage electrostatic adsorber is installed in the reserved space before the air filter. The use and disinfection parameters of the chlorine dioxide disinfection device and the ultraviolet lamp sterilization device can refer to embodiment 2. The high-voltage electrostatic adsorption device produces a DC high-voltage voltage of 4 kV ~ 8 kV. When the indoor air passes through the ...
