Can be circular or square, corresponding dust removal by filtration unit, stainless-steel sheet, the shape of catalyst are corresponded to therewith.It is whole in order to reduce
The resistance of individual reactor, dust removal by filtration unit is typically filtered using stainless (steel) wire, according to actual Dust Characteristics, selects different-thickness
With the stainless (steel) wire in aperture.In addition, in the process of running, it is necessary to regularly replace stainless (steel) wire.
The photochemical catalyst filling mode is direct filling mode or indirect filling mode.
The direct filling mode refers to being placed directly in photocatalyst granular in plasma discharge cells.For
The relatively low organic exhaust gas of dust concentration, are adapted to use direct filling mode.Now, photochemical catalyst is supported on absorption using infusion process
On agent particle, photochemical catalyst can not only effectively adsorb organic exhaust gas, increase the concentration of reaction zone pollutant, greatly improve region of discharge
Interior plasma reaction efficiency and light-catalyzed reaction efficiency, and graininess photochemical catalyst specific surface area is big, catalytic reaction effect
More preferably.Adsorbent can be the non-carbon base adsorbents such as diatomite, molecular sieve or activated alumina.
Present invention additionally comprises carrier, the photochemical catalyst and carrier mixing compacting form cellular packing layer, described to fill out
The bed of material is fixed in plasma discharge cells, and described filler layer is provided with the gas channel of several insertions along airflow direction,
The photochemical catalyst and carrier mixing compacting form cellular packing layer for indirect filling mode.It is higher for dust concentration
Exhaust-gas treatment, the indirect filling mode of preferable packing layer.Packing layer is preferably cellular structure, is mixed by photochemical catalyst and carrier
Combined pressure system is formed.
Preferably, being provided with two plasma discharge cells in the housing.According to exhaust-gas treatment amount and treatment effeciency,
Changeable discharge cell.
The photochemical catalyst is Mn-TiO2Composite catalyst.Mn catalyst is low temperature catalyst, can decompose discharge process
The O of middle generation3, generate active O atom and be attached to catalyst surface, the degraded of organic exhaust gas is promoted at a lower temperature, by Mn-
TiO2Catalyst is combined, and can greatly improve catalytic efficiency.
The aperture of the through hole is preferably 1~2mm, and the photocatalyst granular diameter is preferably 1.5~2.5mm.Through hole
The size in aperture can be adjusted according to actual conditions, it is therefore an objective to reduce gas-flow resistance as far as possible.Simultaneously in order to ensure catalyst particles
Grain is preferably retained in region of discharge, and photocatalyst granular diameter is slightly larger than through-hole diameter.
The aperture of the through hole is preferably 1~2mm, and the gas channel diameter of the catalyst filling layer is preferably 1~
2mm, gas channel diameter is identical with through-hole aperture.Carrier is Al2O3、SiO2, one or more in zeolite.This several carrier
All it is preferable organic waste-gas adsorbant, the organic matter after absorption can be decomposed removing in region of discharge and photocatalytic region.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, plasma oxidation, photochemical catalytic oxidation and suction-operated are organically combined, realizes thoroughly dividing for organic exhaust gas
Solve and innoxious, plasma and photocatalysis can mutually promote, synergy, effect is protruded.
2nd, plasma discharge and photochemical catalyst are placed in a plasma discharge cells, according to exhaust-gas treatment need
Ask, plasma discharge cells changeable is directly filled in combination with catalyst granules, or supported catalyst packing layer not
Same filling mode, can meet different engineering demands.
3rd, gas channel two ends are positioned over as discharge electrode using porous stainless steel plate, can not only realize the equal of air-flow
Cloth, and the strong ultraviolet light that discharge process is produced can be conducted effectively to catalyst surface, promotion electric discharge has with photochemical catalyst
Machine is combined.Simultaneous reactions device overall structure is simple and practical, is easy to the amplification application of industry.
4th, this invention plasma and photocatalysis collaboration plays a role, what photochemical catalyst can produce plasma process
O3O, OH strong oxidizer are converted into for cleaning organic waste gas, while plasma can not only replace ultraviolet light as photocatalysis
The driving source of agent, and structure of reactor in the presence of single Ultraviolet can be overcome to be catalyzed, light source limitation, electronics and hole-recombination,
Treatment effeciency is not high, capacity usage ratio is low, photocatalysis performance is low, can not process high concentration, big flow waste gas, energy efficiency low
Problem.
5th, the present invention is first passed through after dust removal by filtration unit removes particulate matter and processed by plasma discharge cells again,
Whether dust or particle can be processed, and cleaning organic waste gas effect is good, and shell inner surface is caused using reflecting material
