Description
Technical field
The present invention relates to a kind of TiO
2photo catalysis reactor, relates in particular to a kind of photo catalysis reactor of metal honeycomb plate carried catalyst for organic pollutant degradation that adopt.
Background technology
Photocatalysis oxidation technique is new technology, the new method growing up in the last thirty years the seventies in last century.With TiO
2can be H by the organic matter degradation in waste water effectively as catalyst
2o, CO
2, the inorganic molecules such as sulfate ion, phosphate anion, nitrate ion, halide ion, reach the object of complete inorganicization.
But photocatalysis oxidation technique exists many deficiencies and restraining factors in actual applications:
The first, quantum benefit is low, simple TiO
2the right recombination rate again in the light induced electron-space of photochemical catalyst is high, and photocatalysis performance is outstanding.Lower photo-quantum efficiency has limited the industrial applications of photochemical catalytic oxidation;
The second, TiO
2selective adsorption is poor, the product C O of light-catalyzed reaction process
2very easily be adsorbed on catalyst surface and greatly reduce the speed of light-catalyzed reaction and selective;
The 3rd, organic pollutant degradation intermediate product complexity, actual waste water is of a great variety, all kinds of water quality differs greatly, contaminant degradation difficulty degree varies, and mechanism is different, between component, there is competitive reaction, restricted to a certain extent the commercial application of photocatalysis technology;
The 4th, effective distribution of photochemical catalyst and ultraviolet source and fusion problem;
Below be what time realize photocatalysis oxidation technique industrial applications essential technology and the technological problems solving.
In photocatalysis patent and document at home and abroad, all adopt suspended state or be attached on hollow glass ball, plastic foam, resin, wood chip, helical structure carrier, how empty pottery and filament and make to suspend or be fixed on reactor for the nano titanium oxide of photocatalysis to degrade organic matter, its two kinds of modes mainly exist catalyst and cannot effectively contact and fusion and the difficult problem reclaiming of catalyst with ultraviolet light.Meanwhile, no matter be that suspended state or filled type are fixed, all can cause the loss of catalyst because fluid or air-flow stir, and make catalyst loss.Finally cannot meet the industrialization of photocatalysis water technology.
From current domestic and international patent, in patent 201310348060.8, mention a kind of TiO
2the preparation method of photocatalysis ceramic honey comb net, is using ceramic honey comb net as catalyst carrier, but the method step complexity that this patent provides, finally also because of the low gas treatment that is only applicable to of attached catalyst mechanical strength; That simultaneously higher, the production of ceramic honey comb cost and cutting technique require is high, specific area is low, this some restricted this technique and the application of material in extensive water treatment industry.In patent 200910303709.8, mention a kind of catalytic reactor, just can obviously judge that intuitively this reactor can make to enter sewage and accelerate processing water mixing rate because of the water inlet of airflow stirring and dividing plate lower end in actual application, finally cannot effectively utilize the baffling design of reactor itself, the water quality of output water also can be poor.
So can resolved vector cost, a kind of reactor that can efficiently utilize the useful space is provided is simultaneously the basic route that solves a photocatalysis organic wastewater treatment process difficult problem for specific area and catalyst attachment issue.
Summary of the invention
Problem solved by the invention be to provide a kind of can be fast, long-term, effectively organic wastewater degraded is processed and the catalyst monolith plate treatment facility of sterilizing.
In order to reach above object, it is 5-20mm that the metal honeycomb plate of photocatalytic degradation provided by the invention generally adopts aperture, the metallic aluminium that thickness is 10-50mm or iron plate, and its size is carried out cutting according to reactor designing requirement.
The reactor of this application cellular board catalyst, comprise casing, cellular board carried catalyst, uviol lamp, aeration parts, intake-outlet, it is characterized in that: in casing, be provided with multiple independently catalytic reactions storehouse, reaction warehouse is the inferior horn water outlet at angle water inlet and its diagonal angle, and water pipe is connected with elbow and vertical form of placing realizes.In reaction warehouse, the cellular board that has solidified catalyst is placed in layering, retains certain distance between cellular board, places ultraviolet lamp tube in the middle of two plates; Middle, bottom at reaction warehouse arranges micropore aeration pipe; Tank ends is provided with into water and delivery port.
Cellular board is placed the number of plies and thickness can be according to the power determination of the water quality of processed sewage and ultraviolet lamp tube; The width of cellular board and length are with the power determination of fluorescent tube.
