A forced circulation air duct air purification structure

technical field

The utility model relates to an air purification structure of a forced circulation air duct.

Background technique

At present, the air purification technologies used in various forced circulation air ducts mainly include adsorption, static electricity, negative ions, low-temperature plasma, photocatalysis, and ozone. However, the equipment using the above technologies for purification may require frequent replacement of the liner and easily produce secondary pollution, or its killing mechanism cannot coexist with humans and machines, or the killing effect is not ideal, or the use of multiple purification materials superimposes to increase ventilation Therefore, it is difficult to meet the requirements of killing high-concentration and multi-species bacteria and viruses in large public places such as hospitals.

Chinese utility model patent 200420095397.9 discloses a strong oxidation-reduction potential ionic water air purifier. Although the purification structure in the air duct of the air purifier can realize man-machine coexistence, there are relatively few filter materials in the air duct, which reduces ventilation resistance and can Supplement sterilized and purified fresh air into the closed space, but its sterilizing ability, ventilation ability and the thoroughness of sterilizing still need to be improved.

Contents of the invention

The purpose of the utility model is to provide an air purification structure of a forced circulation air duct with good sterilization and disinfection effect, comprehensive purification function, small ventilation resistance and low cost.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

A forced circulation air duct air purification structure, comprising an ozone water mist generating device, the outlet end of the device is arranged in a forced circulation air duct with an air inlet and an air outlet, and the outlet end of the ozone water mist generating device is connected to the An ultraviolet light generating device is arranged in the air duct between the air outlets of the forced circulation air duct.

The above-mentioned forced circulation air duct can be an air-conditioning air duct, an air purifier air duct or other forced ventilation air ducts.

The above-mentioned ultraviolet light generating device can be composed of a frame, an ultraviolet lamp and an ultraviolet lamp bracket. The frame is fixed on the air duct wall or connected with the adjacent frame. The ultraviolet lamp is fixed in the frame through the bracket, and the inner wall of the frame is made of reflective material.

The above-mentioned ultraviolet lamp is an ultraviolet lamp tube, and the lamp tube is arranged parallel to or perpendicular to the wind direction, and a cleaning brush is vertically arranged at the windward end of the lamp tube.

The above-mentioned ultraviolet light generating device is close to the air outlet of the forced circulation air duct, and a shading plate is arranged at the air outlet to prevent ultraviolet light from being emitted.

Because the utility model adopts the above-mentioned structure, the photocatalysis of ozone water is utilized, and the ozone water mist produced by the ozone water mist generating device is under the action of ultraviolet light, so that the ozone in the water is quickly converted into hydroxyl radicals (-OH), This highly chemically active hydroxyl radical can decompose a large amount of harmful gases such as formaldehyde, benzene, and ammonia in the air in the air duct; the hydroxyl radical can directly destroy the cell membrane of the bacteria and cause the bacteria to die; the hydroxyl radical can also directly coagulate the virus The protein of the virus denatures and inactivates the protein of the virus to achieve the effect of destroying the virus. In addition, the circulating air duct adopting the device does not need a filter, thereby reducing wind resistance, saving energy consumption, and effectively reducing hardware costs for air purification of the circulating air duct.

Detailed ways

As shown in Figures 1 to 3, the utility model consists of an ozone water mist generating device 2 and an ultraviolet light generating device 3. The outlet end of the ozone water mist generating device 2 is arranged in a forced circulation air duct 1 with an air inlet and an air outlet; the ultraviolet light generating device 3 is arranged at the outlet end of the ozone water mist generating device 2 and the air outlet of the forced circulation air duct in the air duct between. The forced circulation air duct 1 can be an air conditioner air duct, an air cleaner air duct or other forced ventilation air ducts.

The ozone water mist generating device 2 adopts the structure disclosed in Chinese patent 200420095397.9, which includes a water mist generator 21 and a strong oxidation-reduction potential ion water generator 22, and an atomizer is arranged in the water mist generator; strong oxidation-reduction potential The outlet of the ionized water generator is connected to the atomizer, which is an ultrasonic atomizer or a high-pressure atomizer; the inlet of the water mist generator is connected to a pipeline connected to the outside, and its outlet is connected to no less than one mist The other end of the mist delivery pipe is connected to the forced circulation air duct. The strong oxidation-reduction potential ion water generator has an upper water tank and a lower water tank, and a return pipe and a water supply air pipe are arranged between the upper water tank and the lower water tank; an ultrasonic atomizer and a water outlet are installed in the upper water tank; A bioactive carbon filter is set; the upper water air pipe has a built-in light source and is filled with photocatalyst materials, and its open end and closed end are placed in the upper water tank and the lower water tank respectively, and its closed end is connected with a water pump and an ozone generator respectively.

The ultraviolet light generating device 3 is composed of a frame 31 , an ultraviolet lamp 32 , an ultraviolet lamp support 33 , a shading plate 34 and a cleaning brush 35 . The frame 31 is closely connected with the air duct wall or adjacent frames. The ultraviolet lamp 32 is fixed on the center of the frame 31 by a bracket 33 . Reflective material can be used on the inner wall of the frame 31 to enhance the intensity of ultraviolet light. The ultraviolet lamp can be installed horizontally with the wind direction in the air duct 31, and can also be installed vertically. A cleaning brush 35 can be installed to ensure the cleaning of the lamp tube surface. The distance between the ultraviolet lamp 32 and the frame 31 can be designed according to the energy of the ultraviolet light of the ultraviolet lamp adopted, and a plurality of such devices can be used in combination for the air duct with a larger cross-section. If the installation position of the ultraviolet light generating device 3 is close to the air outlet of the air duct, a shading plate 34 can be added between the air outlet and the device to avoid the leakage of ultraviolet light.

When the utility model works, the ozone water mist produced by the ozone water mist generating device enters the air duct and mixes with the air in the air duct. When passing through the ultraviolet light generating device, under the action of ultraviolet light, the ozone in the water is converted into hydroxyl (- OH) free radicals, because hydroxyl free radicals have a strong ability to kill bacteria and viruses and degrade most harmful gases, so the air passing through the air duct can be completely purified.

After the air is purified, users who have specific requirements for dust can install suitable filters in the air duct as needed.
