This air purifier has a self-cleaning function. A metal filter is installed at the fan. When the wind direction is changed, the fan can blow off the dust on the metal filter to keep the metal filter clean. When the fan is working, the wind direction of the two fans is the same, so that the air flow rate is increased and the gas residence time is reduced.
所述棒状纳米二氧化钛光催化剂负载在空气净化装置内腔表面，所述紫外灯（或日光灯）安装在光催化装置内腔的任意一个表面，所述光催化装置下部留有开口，并用金属搭扣锁将其密封。The rod-shaped nano-titania photocatalyst is loaded on the surface of the inner cavity of the air purification device, the ultraviolet lamp (or fluorescent lamp) is installed on any surface of the inner cavity of the photocatalytic device, and an opening is left at the lower part of the photocatalytic device, and a metal buckle is used The lock seals it off.
需要说明的是，所述棒状纳米二氧化钛光催化剂棒长为15~30nm，直径为5~10nm，吸收光谱红移到750nm，在紫外光下和日光灯下均对恶臭气体具有优秀的光催化活性。It should be noted that the rod-shaped nano-titania photocatalyst rod is 15-30 nm in length, 5-10 nm in diameter, and the absorption spectrum is red-shifted to 750 nm, and has excellent photocatalytic activity for malodorous gases under both ultraviolet light and fluorescent lamps.
本实施例中，二氧化钛光催化剂可以长期使用，不用更换。作为一种变换，若需要更换二氧化钛光催化剂，可以打开金属搭扣锁，拆掉紫外灯管后进行重新喷涂。In this embodiment, the titanium dioxide photocatalyst can be used for a long time without replacement. As a change, if you need to replace the titanium dioxide photocatalyst, you can open the metal hasp lock, remove the UV lamp and re-spray.
所述一种畜禽养殖大棚用的光催化空气净化器具有自清洁功能，在所述风机外安装金属过滤网，当改变气体流向时，可以吹出吸附在金属过滤网上的灰尘；定期打开金属搭扣锁，吹出内腔表面少量灰尘，以保持光催化效率。The photocatalytic air purifier for livestock and poultry breeding greenhouses has a self-cleaning function. A metal filter screen is installed outside the fan. When the gas flow direction is changed, the dust adsorbed on the metal filter screen can be blown out; Snap lock to blow out a small amount of dust on the surface of the inner cavity to maintain the photocatalytic efficiency.
本实施例中，In this embodiment,
工作过程：风机将污染气体通过金属过滤网抽到进风装置里面，然后经过多个光催化装置，在光催化装置内，纳米二氧化钛光催化剂对污染气体进行降解，并且杀灭空气中的细菌等微生物，降解后的气体通过出风装置排出。使畜禽养殖大棚内的空气质量得到改善。Working process: The fan draws the polluted gas into the air inlet device through the metal filter, and then passes through multiple photocatalytic devices. In the photocatalytic device, the nano-titanium dioxide photocatalyst degrades the polluted gas and kills bacteria in the air, etc. Microorganisms, the degraded gas is discharged through the air outlet. Improve the air quality in livestock and poultry breeding greenhouses.
