H keys, decomposing organic matter CO2And H2O, meanwhile, bacterial cell membrane and solidification virus protein are destroyed, the life of bacterium, virus is changed
Dis environment is to kill bacterium, virus.
Treatment effeciency to improve exhaust gas treatment unit 100 can be with profit other than using the ultraviolet light that UV lamp is provided
Use sunlight.
For this purpose, in the present embodiment, exhaust gas treatment unit 100 further includes having light transmitting shell 130, and light transmitting shell 130 is sleeved on
On outermost layer substrate 112.
Sunlight can be irradiated to the inside in photocatalyst portion 110 by light transmitting shell 130, to increase the purple inside photocatalyst
Outside line exposure, and improve the treatment effeciency of exhaust gas treatment unit 100.Meanwhile solar energy utilizes solar energy as clean energy resource
As supplementary energy, the consumption of electric energy can be dramatically saved.
Light transmitting shell 130 includes quartz glass.
In the present embodiment, light transmitting shell 130 can be made using quartz glass.In other specific embodiments, also may be used
Using the outline border of the materials such as stainless steel, light transmitting shell 130 is made after installing quartz glass on outline border.
In view of needs such as practicability and installations, the setting of light transmitting shell 130 is also in cylindrical tube shape.The axis of light transmitting shell 130
Heart line is conllinear with the axial line of internal substrate 111.
In the present embodiment, exhaust gas entrance pipeline and waste gas outlet pipeline, exhaust gas entrance pipe are provided in photocatalyst portion 110
Road and waste gas outlet pipeline are located at the both ends in photocatalyst portion 110.On exhaust gas entrance pipeline and on waste gas outlet pipeline
Flange is arranged, connected by flange and the installation of light transmitting shell 130.
In addition, UV lamp pipe 120 is also required to be fixed.For fixed UV lamp pipe 120, can be set at the both ends of UV lamp pipe 120
Holder is set, is installed on the axial line inside internal substrate 111 by holder.
It is both provided with wasted nickel catalyst hole on exhaust gas entrance pipeline and waste gas outlet pipeline.It can be acquired by wasted nickel catalyst hole
By exhaust gas before photocatalyst portion 110 and pass through the exhaust gas behind photocatalyst portion 110.
In order to will be seen that the disposition for detecting exhaust gas treatment unit 100 to exhaust gas, on exhaust gas treatment unit 100
VOCs wasted nickel catalyst instrument is set, and the probe of VOCs wasted nickel catalyst instrument is located in wasted nickel catalyst hole.VOCs wasted nickel catalyst instrument
Probe can be convenient for work people by wired or wirelessly by the data transfer detected to computer or mobile phone terminal
Member checks.
In existing technology, the device primary structure of exhaust gas is administered using photocatalyst is：In the photocatalyst base being arranged side by side
More UV lamps are set between plate, and shell is opaque plank.This device volume is big, high to the area requirements of fabricating yard,
But also there is a problem of that the quantity of illumination and light-receiving area are insufficient.Simultaneously as increasing for UV lamp quantity, also results in production cost
And the increase of power cost.
And in the present embodiment, only selection uses 1 UV lamp pipe 120, and is positioned in the internal substrate of cylindrical tube shape
111 and outermost layer substrate 112 axial line on.This ultraviolet light for making UV lamp pipe 120 generate radially is irradiated in photocatalyst portion 110
Inside, expand photocatalyst reaction area, realize high energy-efficient purpose.
Simultaneously as internal substrate 111, outermost layer substrate 112 and light transmitting shell 130 all use the structure of cylindrical tube shape,
So that the volume of exhaust gas treatment unit 100 becomes smaller, its production, assembling and transport etc. is made all to become very convenient.And because body
Long-pending becomes smaller, and requirement of the exhaust gas treatment unit 100 to fabricating yard area is also made to be lower.I.e. exhaust gas treatment unit 100 can be straight
Connect it is lateral, longitudinal or diagonally-installed on VOCs exhaust emission pipes, without directly occupying surface area.
(for example 5000m is handled with previous same exhaust gas conditions3/ h exhaust gas) under 3 sections of photocatalyst substrates of laid out in parallel (use
20 UV lamps) effective photocatalyst area be 4.8 ㎡ compare, the exhaust gas treatment unit 100 proposed in the present embodiment its effectively
Photocatalyst area is 24.1 ㎡, is 5.4 times of conventional art, only expands effective photocatalyst reaction area one and conventional art phase
Than enlarged i.e. 4.4 times, just save 87 fluorescent tubes, 81.3% whole electric energy of 13 pieces of photocatalyst substrates, luminous energy, investment and
Place etc..
Exhaust gas treatment unit 100 uses light transmitting shell 130 so that it can receive ultraviolet in the sunlight of different directions
Line.The solar energy middle-ultraviolet lamp being irradiated on ground accounts for 5%, ultraviolet irradiation intensity average out to 1mW/cm2, number of photons is about
1015A/scm2, it is room light exposure intensity (1 μ W/cm2) 1000 times, the enough ultraviolet illuminations of high intensity are guarantee amounts
The premise and basis of sub- efficiency.
Exhaust gas treatment unit 100 receives the amount of ultraviolet in sunlight through light transmitting shell 130 and is up to 80% or more, with
Previous equipment uses illuminance 300Lx, 2.7 μ W/cm of amount of ultraviolet2San Bo Chang Fluorescent light shape N colors (Japanese fluorescent tube) compare, receive
The amount of ultraviolet of sunlight and 1 UV lamp pipe 120 (for example handles 5000m than same exhaust gas conditions3/ h exhaust gas) use 20
The amount of ultraviolet that UV lamp generates is 52 times big.
And since 100 illumination of exhaust gas treatment unit is without dead angle, so in dichloromethane, 1,2- bis- of the processing containing chlorine atom
When the VOCs such as chloroethanes, chloroform, trichloro ethylene or tetrachloro-ethylene, micro and extremely harmful phosphinylidyne can be greatly reduced
The generation of the intermediate products such as chlorine, chlorine, hydrogen chloride.
In the present embodiment, it is also proposed that a kind of exhaust treatment system, including exhaust gas treatment unit 100, wind turbine etc..
It will be appreciated by those skilled in the art that the accompanying drawings are only schematic diagrams of a preferred implementation scenario, module in attached drawing or
