Further, the heat abstractor includes the first heat abstractor and the second heat abstractor, first heat abstractor
Set close to the UV photocatalysis treatments device, first heat abstractor is set close to the plasma generator.
Further, the plasma generator includes minus plate and positive plate, and the minus plate and positive plate, which connect, to be set
In on the superimposed pulse plasma power supply of tributary.
Further, the minus plate and positive plate are stainless steel plate.
Compared with prior art, the beneficial effect of VOCs emission-control equipments of the invention is：
(1) the VOCs emission-control equipments that the present invention is provided are used to handle volatile organic compound from waste gas, and it is included just
Level screen pack, UV photocatalysis treatments device, plasma generator and activated carbon filter layer.Pass through UV photocatalysis treatments device and plasma
Generator mutual cooperation work, is handled for the VOCs waste gas of heterogeneity, by the cooperation of UV light and plasma,
Thoroughly volatile organic matter gas treatment can be fallen, realize nontoxic, innoxious.
(2) the VOCs emission-control equipments that the present invention is provided have compact overall structure, and floor space is small, purification efficiency
Height, the characteristics of equipment operating cost is low.
To enable the above objects, features and advantages of the present invention to become apparent, preferred embodiment cited below particularly, and coordinate
Appended accompanying drawing, is described in detail below.

Primary filter net 2 in body 1, the dust granules in VOCs waste gas are separated with waste gas, to carry out follow-up processing.Just
VOCs waste gas enters UV photocatalysis treatments device 3 after level filtering, and UV photocatalysis treatments device can produce UV light (ultraviolet), and VOCs gives up
Volatile organic matter gas in gas issues biochemical reaction in the irradiation of UV light, most of organic substance be degraded to water,
The simple harmless compound such as carbon dioxide.Then, the VOCs waste gas of the organic matter containing difficult degradation goes successively to plasma hair
In raw device 4, plasma generator 4 produces plasma and simultaneously the VOCs waste gas passed through is bombarded, the plasma of high energy and
VOCs waste gas interacts, and the organic matter of difficult degradation is decomposed into harmless small molecule by macromolecular or is occurred chemical reaction life
Into harmless material.UV photocatalysis treatments device 3 and the mutual cooperation work of plasma generator 4, give up for the VOCs of heterogeneity
Gas is handled, by the cooperation of UV light and plasma, thoroughly can be fallen volatile organic matter gas treatment, is realized
It is nontoxic, innoxious.Finally by the further adsorption cleaning of the suction-operated of activated carbon filter layer 5, pure air is obtained by going out
Gas port 12 is discharged.
Preferably, primary filter net 2 is HEAP high efficiency particulate airs.HEAP high efficiency particulate airs also known as high efficiency particle air filter,
The screen pack of HEPA standards is reached, the characteristics of HEPA is netted is that air can pass through, but tiny particulate can not pass through；It is to straight
Footpath be the particle removal efficiency of 0.3 micron (1/200 of hair diameter) below can reach more than 99.97%, be smog, dust with
And the maximally effective filtering medium of pollutant such as bacterium.HEPA points of PP filter paper, glass fibre, compound PP PET filter paper, melt-blown terylene
Non-woven fabrics and melt-blown five kinds of materials of glass fibre.It is excellent that HEAP high efficiency particulate airs have that windage is big, dust containing capacity is big, filtering accuracy is high
Point, various sizes and shape can be processed into as needed.
