Abstract
The photocatalytic reactor for degrading contaminant in waste water and waste gas consists of cylinder, light conducting device and light distributing device. The cylinder has mouth, the light distributing device consists of light fiber and photocatalyst particles carried by the light fiber, and there is fiber coupler between the light conducing device and the light distributing device for connection. The use of the fiber coupler makes it possible to adopts different fiber in the light conducting device and to raise contaminant degrading capacity.
Description
The present invention relates to a kind of device that is used for waste water or waste gas Pollutant Treatment, refer in particular to light catalytic reactor for contaminant degradation.
The structure of existing photo catalysis reactor is that the lower end protective layer of optical fiber is peelled off; apply photocatalyst thereon; and be placed in the reactor shell; therefore; the part of every optical fiber in this photo catalysis reactor is to pass the light district; and another part is workspace, and optical fiber is thin more, and to pass optical efficiency high more passing the light district; yet; optical fiber is thin more, and is short more in the axial propagation distance of workspace light, causes the photochemical catalysis area to diminish; restricted ability to contaminant degradation; optical fibre set, then filling ratio is low, and light transmissioning efficiency is low.In addition, optical fiber catalysed partial in reactor is owing to lack the covering protection, and flexural strength is low, and anti-brittle failure ability is difficult to use on a large scale.
Goal of the invention of the present invention is to provide a kind of light catalytic reactor for contaminant degradation that helps improving pollutent ability in degrading waste water or the waste gas.
The present invention adopts following technical scheme to realize its goal of the invention:
The present invention is a kind of light catalytic reactor for contaminant degradation that is used for waste gas/wastewater treatment, form by reactor shell 1, biography optical device 2 and luminous intensity distribution device 3, on reactor shell 1, be provided with mouth 11, luminous intensity distribution device 3 is made up of optical fiber 31 and photocatalyst granular, photocatalyst granular loads on the optical fiber 31, between biography optical device 2 and luminous intensity distribution device 3, be provided with fiber coupler 4, pass optical device 2 and be connected with luminous intensity distribution device 3 by fiber coupler 4.
Compared with prior art, the present invention has following advantage:
1. in the present invention, passing optical device is to be connected with the luminous intensity distribution device by fiber coupler, this just makes and passes optical device and both can adopt identical optical fiber with optical fiber in the luminous intensity distribution device, also can adopt different classes of or different diameter fibers, make the available scope that passes the optical fiber in optical device, the luminous intensity distribution device very big, can select with light-catalysed different requirements according to passing light, distribute rationally, reach the best light effect that passes, and can steady in a long-termly move, thereby make the present invention can realize helping improving the purpose of degradation of contaminant ability.
2. because the existence of fiber coupler makes the present invention can select thicker longer photocatalyst optical fiber, thereby increased reaction area, improved the effect of mass transfer, reaction.
3. stranding biography optical device can improve the biography optical efficiency, linear optical fiber then can be grown apart from lateral emitting, and the present invention can make up it by fiber coupler, thereby, improve quantum yield and speed of reaction, more helped improving the ability of degradation of contaminant of the present invention.
4. the present invention places quartz socket tube with optical fiber, has improved the photochemical catalysis area of unit volume in the reactor, and casing buckling intensity height, and anti-brittle failure is good.
5. the bundle dividing orchestration can be divided into some bundles with the optical fiber that passes in the optical device, thereby has increased reaction area, has improved mass transfer effect and speed of reaction, has further improved the degradation capability of the present invention to pollutent.
6. can in reactor shell, blast air/oxygen by ventilating pit 12, further promote the carrying out of light-catalyzed reaction, gas and liquid mixing are got evenly, help waste water or off gas treatment.
