Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

See Figure 1 and Figure 2, a central air-conditioning air disinfection, sterilization and purification device, the shell 1 is made of aluminum alloy plate or plastic steel and other materials into a cylindrical structure with two small ends, a large middle, and a rectangular or circular cross section. , the cylinder is a disinfection and purification chamber, and the disinfection and purification chamber has two ports, one end is used as an air inlet, and the other end is an air outlet; flanges 2 and 2 are respectively welded at the air outlets of the shell 1 The size of the air outlet pipe and the air return pipe of the central air conditioner are consistent in size, so that the device can match each other when embedded in the air outlet pipe or return air pipe. An activated carbon filter screen 3 perpendicular to the central axis of the pipeline is respectively provided at the middle section with a larger cross-section in the housing 1 near the air inlet end and the air outlet end; between the two activated carbon filter screens 3, a Two titanium dioxide photocatalyst filter screens 4 that are perpendicular to the central axis of the pipeline and spaced from each other; on the opposite wall in the pipeline between the two titanium dioxide photocatalyst filter screens 4, there are respectively more than one pair of ultraviolet generators 5; in the titanium dioxide photocatalyst filter The net 4 is provided with at least one pair of negative oxygen ion generators 6 and at least one pair of ozone generators 7 in turn near the air outlet side; a main control board is arranged on the housing 1 of the disinfection and purification chamber to generate negative oxygen ions respectively. Device 6, ultraviolet generator 5, ozone generator 7 are connected, and control panel is used for negative oxygen ion generator 6, ultraviolet generator 5, ozone generator 7 is controlled.

The working principle of the central air-conditioning air disinfection, sterilization and purification device is: the device is embedded in the central air-conditioning air outlet duct or return air duct, so that the air in the central air-conditioning air duct enters through the air inlet end of the disinfection, sterilization and purification chamber, and is discharged from the disinfection, sterilization and purification chamber. The air outlet end flows out and enters the original air duct of the air conditioner, forming a complete loop. After the air in the central air-conditioning duct is introduced into the disinfection and purification chamber, it first passes through the activated carbon filter 3, and the activated carbon filter 3 filters the air to absorb and filter out dust and other particles and some bacteria; the filtered air enters the pipeline Two titanium dioxide photocatalyst nets 4 arranged vertically on the axis, an ultraviolet generator 5 is arranged between the two photocatalyst nets, the spectrum generated by the ultraviolet generator 5 activates titanium dioxide to generate active oxygen, and kills microorganisms, viruses and bacteria, and the remaining At the same time, active oxygen also degrades formaldehyde, benzene, ammonia and organic compounds, and removes toxic and harmful gases; the air after filtration and sterilization enters the third link, which is installed on the inner wall of the disinfection and purification chamber The ozone produced by the ozone generator 7 sterilizes the air again to remove peculiar smells. At the same time, the negative ions produced by the negative oxygen ion generator 6 installed next to the ozone generator 7 supplement and regulate the freshness and quality of the air ; After the air in the previous link is filtered through the activated carbon filter, the carbohydrates and all residues are adsorbed and filtered; so far, the air in the air-conditioning pipeline is disinfected, sterilized and purified, and the quality of the air entering the room is improved.
