Problems solved by technology

[0002] At present, conventional air sterilization and disinfection methods are mainly chemical methods and physical methods. The former often uses various chemical substances, which cause potential harm to the human body and the environment, while the latter often uses ultraviolet rays or ions, etc., and the sterilization effect is not good. Obviously, or it has no effect on some bacteria and viruses, and the ion method also has the possibility of producing harmful substances such as ozone, etc.
[0003] As we all know, when the temperature rises or falls to a certain level, bacteria and viruses cannot survive. Heating food, boiling water, etc. is to use this principle to sterilize and disinfect. This is also the most safe and reliable method that people have used for a long time. Sterilization and disinfection methods, but changing the temperature of the air requires a lot of energy, and the method of air sterilization and disinfection by raising or lowering the air temperature has not been widely used

Embodiment 1

[0024] Such as figure 1 As shown, an air sterilization and disinfection system is composed of a thermal energy device 1 with cooling or heating functions, a fan 4 and pipelines. The thermal energy device 1 is connected to the fan 4 through pipelines; the thermal energy device 1 includes elements 11 . The element 11 can be a heating element or a cooling element, and the heating element is selected from an electric heating element, or a water heating element, a steam heating element, a refrigerant heating element (such as Freon, etc.), an air heating element or a flue gas heating element , the refrigeration element is selected from water refrigeration elements, cold fluid refrigeration elements (such as ethylene glycol, etc.), refrigerant refrigeration elements (such as Freon, etc.).

[0025] The sterilization and disinfection process of this system is as follows: the air A1 from a certain space passes through the thermal energy device 1 and is heated or cooled to become TA, bac...

Embodiment 2

[0030] Such as figure 2 As shown, an air sterilization and disinfection system is characterized in that the system is composed of a heat energy device 1 with refrigeration or heating, a heat recovery device 2, a fan 4 and pipelines, and the heat recovery device 2 includes alternately arranged air intake passages and The air outlet channel, the air intake channel, the thermal energy device 1, the air outlet channel, and the fan 4 are connected in turn through pipelines; the thermal energy device 1 includes an element 11, and the element 11 can be a heating element or a cooling element, and the heating element is selected from Electric heating element, or water heating element, steam heating element, refrigerant heating element (such as freon, etc.), air heating element or flue gas heating element, and the cooling element is selected from water cooling element, cold fluid cooling element (such as ethylene glycol etc.), refrigerant refrigeration components (such as Freon, etc.)....

Embodiment 3

[0036] Such as image 3 with 4 As shown, the thermal energy device 1 and the heat recovery device 2 are integrated, that is, the system is directly composed of elements 11, a plurality of heat exchange walls 31 and fans, and two adjacent heat exchange walls 31 form an air intake channel or The air outlet channel, the air inlet channel or the air outlet channel are arranged alternately; the air inlet channel, the element 11, the air outlet channel, and the fan are connected in sequence, and the element 11 can be a heating element or a cooling element, and the heating element is selected from an electric heating element, or is Water heating element, steam heating element, refrigerant heating element (such as freon, etc.), air heating element or flue gas heating element, and the cooling element is selected from water cooling element, cold fluid cooling element (such as ethylene glycol, etc.), refrigerant cooling Components (such as Freon, etc.).

[0037] Such as Figure 5 As s...

Abstract

The invention discloses an air sterilization and disinfection method and system. According to the method, to-be-sterilized and to-be-disinfected air is sterilized and disinfected at the high temperature or low temperature, or to-be-sterilized and to-be-disinfected air is sterilized and disinfected after subjected to heat exchange in a heat recovery device, and then the air is subjected to heat regeneration through the heat recovery device. According to the air sterilization and disinfection method and system, the air is sterilized and disinfected through air temperature increase or decrease, and the method and the system have the advantages of simplicity, reliability, safety, energy saving and the like.

Description

technical field [0001] The present invention relates to a method and system for air sterilization and disinfection, in particular to a safe, efficient and energy-saving method and system for air sterilization and disinfection by utilizing changes in air temperature without using unnatural means such as chemicals or ions. Background technique [0002] At present, conventional air sterilization and disinfection methods are mainly chemical methods and physical methods. The former often uses various chemical substances, which cause potential harm to the human body and the environment, while the latter often uses ultraviolet rays or ions, etc., and the sterilization effect is not good. Obviously, or it has no effect on some bacteria and viruses, and the ion method also has the possibility of producing harmful substances such as ozone. [0003] As we all know, when the temperature rises or falls to a certain level, bacteria and viruses cannot survive. Heating food, boiling water, ...
