Air purification and sterilization system of enclosed spaces

Abstract

The invention relates to an air purification and sterilization system of enclosed spaces. The air purification and sterilization system of the enclosed spaces comprises an air flow channel, ultraviolet sterilization modules, ultraviolet irradiance sensors and a controller, wherein the air flow channel communicates with the enclosed spaces, and is provided with air inlets, air outlets, and air flues formed between the air inlets and the air outlets; the ultraviolet sterilization modules are provided with ultraviolet light sources arranged in the air flues; the ultraviolet irradiance sensors arearranged in irradiation ranges of the ultraviolet sterilization modules; the controller is connected with the ultraviolet irradiance sensors and the ultraviolet sterilization modules; and the controller has a preset power value, and by comparing the ultraviolet irradiance monitored in real time and the preset power value, power output of the ultraviolet light sources is adjusted. Circular continuous sterilization and air purification are formed between the air purification and sterilization system of the enclosed spaces and the enclosed spaces, man-machine symbiosis can be achieved, disinfection is conducted in real time, and sterilization power is adjusted intelligently and controllably according to the working conditions.

Description

technical field [0001] The invention relates to the technical field of sterilization and purification, in particular to an air purification and sterilization system for a closed space. Background technique [0002] With the improvement of people's health awareness, people are more and more worried about being exposed to sources of infection such as bacteria and viruses in daily life. Although we pay attention to the sterilization of contact surfaces, the air is also a way for germs to spread, even through the mouth and nose. The method can hinder the transmission to a certain extent, but it is not fundamentally sterilizing. At present, the risk of infection is relatively high in relatively closed public spaces, such as elevators, vehicles, offices, shopping malls, restaurants, restaurants, etc. Most of the sterilization and disinfection are carried out by spraying disinfectants Or sterilize by ultraviolet light in some areas, or push the mobile ultraviolet cart into the comp...

[0002] With the improvement of people's health awareness, people are more and more worried about being exposed to sources of infection such as bacteria and viruses in daily life. Although we pay attention to the sterilization of contact surfaces, the air is also a way for germs to spread, even through the mouth and nose. The method can hinder the transmission to a certain extent, but it is not fundamentally sterilizing. At present, the risk of infection is relatively high in relatively closed public spaces, such as elevators, vehicles, offices, shopping malls, restaurants, restaurants, etc. Most of the sterilization and disinfection are carried out by spraying disinfectants or sterilize local areas by ultraviolet light, or push the movable ultraviolet cart into the compartment for irradiation when personnel are away to kill bacteria in the air

[0003] However, the mobility of personnel is strong. With the flow of personnel, this sterilization method cannot be sterilized in real time. For relatively densely populated places, the existing sterilization methods obviously cannot meet the sterilization requirements.
