Oxygen machine and its manufacturing process.
Background technique
In June, 2015, China issues《Volatile organic matter Pollution Charges Site method》, pilot industry includes petroleum
Work, packages printing.This is China's first passage economic means limitation volatile organic matter (Volatile Organic
Compounds, VOCs) discharge.In recent years, relevant policies and regulations and professional standard are even more related to more conglomerate, and
The supervise and examine dynamics of each department environmental protection administration also obviously increases.Therefore, it is numerous at present for finding efficiently applicable VOCs Treatment process
Enterprise's problem urgently to be resolved.The technology for industrially controlling processing VOCs mature at present mainly has：Combustion method, biology drop
Solution, active carbon adsorption, photochemical catalytic oxidation, plasma method and the combination technique between them.
Wherein, UV technology of catalytic oxidization degradation as the technology of popular removal VOCs and foul gas at present it
One, it is widely used in terms of processing low concentration VOCs and foul gas.Its dominant mechanism is：In the effect of high energy ultraviolet
The molecular chain rupture of lower foul gas and volatile organic matter, the oxygen molecule in air, which decomposes, generates free oxygen, free oxygen institute band
Positron-electron is uneven, in conjunction with oxygen molecule after generate ozone；Simultaneously when ultraviolet light is in catalyst TiO2Surface when, week
The oxygen and hydrone enclosed can be generated hydroxyl radical free radical (OH), superoxide radical (O by excitation2 —) and hydrogen peroxide is certainly
By base (HO2) etc. strong oxidizing properties active group, therefore the organic pollutant of small molecule chain can be in ozone and a variety of free radicals
Under the action of be degraded to harmless CO2And H2O.But UV technology of catalytic oxidization degradation there are UV light utilization efficiencies low, exhaust gas at present
Degradation efficiency declines very fast and honeycomb or foam photocatalyst utilization rate is low (i.e.：Effective light radiation area is smaller) etc. technologies ask
Topic.
Chinese patent (103261101 B of CN) discloses a kind of photocatalysis element, " bee of the coated catalyst of air stream
Nest shape " target (is similar to aluminum honeycomb photocatalyst), and UV lamp pipe is radiated on photocatalyst to generate bactericidal properties object by emitting UV light
Matter (ozone and a variety of free radicals).The UV photochemical catalytic oxidation element can shine directly into the UV light that emission source emits on target,
Can the second part UV energy in spontaneous emission in future source be reflected on target.Using mirror-reflection principle and design unique reflection and tie
Structure realizes the higher order reflection of UV light, to improve the ratio that photocatalyst receives UV light energy.But this fully rely on mirror-reflection
Design need to match the optical catalyst carrier of specific structure and be mounted at specific position and can be only achieved preferable effect.Cause
This, the complicated feature of design and installation causes applicability not strong, and manufacturing cost is relatively high.
Chinese patent (CN 105749711A) by shell and other three modules form from bottom to top, i.e. filtering module, light
Oxidation module, catalysis ozone module.Filtering module removes the particulate matters such as dust in air.Photooxidation module, by ultraviolet lamp
Constitute this module core component.But not set photochemical catalyst in its photooxidation module.
Therefore, for UV light utilization efficiency existing for existing UV technology of catalytic oxidization degradation under low, exhaust gas decomposition efficiency
It drops very fast and honeycomb or foam photocatalyst utilization rate is low (i.e.：Effective light radiation area is smaller) etc. technical problems, design and
A kind of high-efficient and lasting, economical and practical and UV photooxidation machine for ease of maintenaince are manufactured, realizes the high usage and honeycomb or foam of UV light
