Of the present utility modelly to be achieved through the following technical solutions: the utility model proposes a kind of VOCs treatment photocatalysis assembly with dust reduction capability, comprise filter gas cylinder, filter bag and be arranged at the uviol lamp assembly of filter gas cylinder interior, described filter bag is arranged at the outside of filter gas cylinder, the sidewall of described filter gas cylinder is provided with some air admission holes, described air admission hole axis is acute angle with filter gas cylinder axis angle, the inwall of described filter gas cylinder is provided with photocatalyst coating, the top of described filter gas cylinder is provided with blowback air tube channel, the bottom of described filter gas cylinder is provided with purified gas escape pipe.
Improve as one, can be that the one in both wire netting or synthetic fibers is made form described filter bag.
As further improvement, described air admission hole can be any one in circular hole or polygonal hole.
As further improvement, following in the top being positioned at the gap slot on filter gas cylinder inner wall lower than the gap slot on outer wall of described air admission hole.
As further improvement, following in the top being positioned at the gap slot on filter gas cylinder inner wall higher than the gap slot on outer wall of described air admission hole.
(3) beneficial effect
The utility model, relative to prior art, has following beneficial effect:
A kind of VOCs treatment photocatalysis assembly with dust reduction capability that the utility model is mentioned, filter gas cylinder arranged outside has the filter bag can removing dust granules in organic exhaust gas, when filter bag outer surface laying dust is thicker, deashing can be realized by blowback air tube channel, filter gas cylinder outer wall is provided with in skewed air admission hole, make organic exhaust gas both can enter into filter gas cylinder, ultraviolet beam can be avoided again to be irradiated to outside filter gas cylinder simultaneously, refer to utilization rate of ultraviolet light, too increase the contact area of organic exhaust gas and photocatalyst coating simultaneously, improve degradation efficiency and clean-up effect.
