Problems solved by technology

Increasing the diameter of the lamp tube or increasing the operating current cannot effectively increase the ultraviolet power; although increasing the length of the lamp tube can increase the total ultraviolet power, but the installation and use of the long lamp tube are not convenient and are very limited
[0005] ② Ordinary ultraviolet lamps are generally exposed and can only work when there is no one to avoid direct exposure to people, which is inconvenient for continuous and dynamic air sterilization, and it cannot be directly placed in water for disinfection and sterilization
[0006] ③When there is dust and dirt on the surface of the ultraviolet lamp tube, it will affect the generation of ultraviolet rays and fail to achieve a good sterilization effect, so the lamp tube needs to be cleaned regularly
However, the cleaning of ordinary ultraviolet lamps is time-consuming, laborious, unsafe and inconvenient, which seriously affects the use of lamps

Embodiment 1

[0051] Such as figure 2 shown. A microwave cavity 1 with a volume of about 26.6 liters is selected (the internal dimensions of the cavity are 320 mm wide, 260 mm high, and 320 mm deep). Eight linear quartz lamp tubes 3 with a diameter of 15 mm and a length of 250 mm are selected. The inner cavity 12 of the lamp tube is filled with an appropriate amount of neon gas, and 1.5 mg of solid mercury 13 is added; the material of the lamp tube shell 11 is mainly high-purity quartz, and a small amount of titanium metal is mixed to form a microwave electrodeless discharge ultraviolet lamp. Tube 3. These eight microwave electrodeless discharge ultraviolet lamp tubes 3 have no electrode, no filament, no power supply, and the light transmission window is at 254nm. Select two rectangular (width 300mm, length 280mm) plastic plates with equal area. There are eight holes with a diameter of 15mm on each of the two parallel plates. The holes are evenly distributed on the plates. The two plate...

Embodiment 2

[0061] The same place as in Embodiment 1 will not be described again, and the difference is that:

[0062]The microwave electrodeless discharge ultraviolet lamp tube 3 is "H" type, with a diameter of 20mm, two parallel sections with a length of 250mm, and a section connected in the middle with a length of 260mm. The inner cavity 12 of the lamp tube is filled with an appropriate amount of krypton gas, and 4 mg of liquid mercury 13 is added. Five microwave electrodeless discharge ultraviolet lamp tubes 3 are used. Five lamp tubes are placed in the microwave cavity 1 in parallel, perpendicular to the direction of the air inlet pipe 6, and perpendicular to the horizontal plane, and the distance between the two lamp tubes is 50mm. The lamp tube is fixed with clips, and the ultraviolet lamp tube support 4 is not adopted. The microwave electrodeless discharge ultraviolet lamp tube 3 is directly exposed to the microwave cavity 1 . The air inlet pipe 6 is a straight pipe, and the ai...

Embodiment 3

[0068] The foregoing embodiments are for disinfecting and sterilizing the air, and the present embodiment is for disinfecting and sterilizing the water. Such as image 3 shown. The same technical content as Embodiment 1 and Embodiment 2 will not be described again, and the difference is that:

[0069] The water inlet pipe 15 is on the right side below the microwave chamber 1, and the water outlet pipe 16 is on the right side above the microwave chamber 1. A water pump 14 is connected to the water inlet pipe 15, and water flows through the microwave chamber 1 from bottom to top under the action of the water pump 14. Two sets of microwave generators 2 connected to the microwave cavity 1 are installed on the left side of the microwave cavity 1, and the output microwave power of each set of microwave generators 2 is 300W. Twenty-six microwave electrodeless discharge ultraviolet lamp tubes 3 were used. Each microwave electrodeless discharge ultraviolet lamp tube 3 is an unclosed...

Abstract

This invention relates to the method, equipment and use of microwave-excited ultraviolet sterilization, and it belongs to sterilization technical sphere. In current technics, ultraviolet is generated by cooperation of common ultraviolet lamp and ballast, and the ultraviolet is low-tenacity and inconvenient to use and maintain; the technics has big limitation and short life. In allusion to those shortages, the invention uses microwave-excited inert gas stored in quartz tube discharge and boiloff hydrargyrum in the tube to generate ultraviolet, and do sterilization to gas or liquid (especially flowing gas and liquid) that passed through the microwave cavity. This invention has good sterilization effect and long life; it is convenient to use and clean, safe and cheap; it can be independency used or matching used with air conditioning, air freshener and other equipments.

Description

technical field [0001] The present invention relates to a method, equipment and application of disinfection and sterilization, in particular to a method and equipment for generating ultraviolet rays by using microwave excitation, and the use of the method and equipment for disinfection and sterilization of flowing gas and liquid. It belongs to class A61L in the International Patent Classification. Background technique [0002] Now people pay more attention to health than ever before. Many companies and research institutions are developing and producing disinfection and sterilization methods and products for air, water and other substances that are closely related to people's lives, so as to adapt to the increasingly serious environmental pollution in the future. disease transmission. The use of ultraviolet light for disinfection and sterilization is a commonly used method at present. The UVC band (190nm~290nm) of ultraviolet light has the function of disinfection and steri...
