Description
Technical field
The present invention relates to the photocatalytic reaction device for water treatment, belong to technical field of sewage in environment protection.
Background technology
Traditional water treatment method efficient is low, cost is high, have secondary pollution problems, the solution that waste water control can not get always.1972, A. Fujishima and K. Honda were at N-shaped semi-conductor TiO
2Found the photoelectrocatalysis Decomposition of water on electrode, TiO
2Oxidation activity is higher, and chemical stability is good, and to the human body toxicological harmless, cost is low, and is pollution-free, applied range, thereby paid attention to most, be present most widely used nano-photocatalyst material, be also the environmental type catalyzer that has most the exploitation future.Nano-TiO
2Can process multiple toxic compounds, can with the hydro carbons in water, halohydrocarbon, acid, tensio-active agent, dyestuff, itrogenous organic substance, organic phosphorous insecticide, wood preservative and fuel wet goods soon complete oxidation be CO
2, H
2The innoxious substances such as O.But nano-photo catalytic TiO up to the present
2Technology is not used widely aspect wastewater treatment yet, is mainly because the nano particle separation difficulty does not have simple applicable treatment facility.
In the carrier surface load, can solve the problem of particle separation by nano particle.But when load had the carrier of nano particle to be soaked in water, the solution that exciting light must see through thicker (often more than several centimetres) just can shine on catalyzer.And in fact, no matter be at ultraviolet region or visible region, organic solution (especially with the look organic wastewater) all can have photoabsorption in various degree, this will certainly cause exciting light light loss in various degree, make the light intensity that arrives catalyst surface descend, thereby make the productive rate in light induced electron and hole descend, finally make the degradation efficiency of pollutent reduce.
Patent publication No. is that CN100509639C discloses a kind of ramp type photo electrocatalysis reactor, can obtain preferably water thin film and promote light-catalyzed reaction, but lamp is placed in the swash plate outside, has the loss of light.Equally, patent publication No. is that CN101774661A, CN102030387A, the disclosed method of these patents of CN101993129A are all excitation light source to be positioned over the side of catalyst cupport plate, has the loss of luminous energy.In order to improve degradation efficiency, can only improve the power of excitation light source, so just increased operation energy consumption.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, propose a kind of conical drum formula photocatalytic reaction device that can guarantee that exciting light does not run off to be wasted.
The technical solution used in the present invention is: comprise a cone cylinder, the large end of cone cylinder and the opening part of small end are sealed with end socket, the coaxial extension tubular shaft in the two ends of cone cylinder, and tubular shaft connects electric motor; In cone cylinder and tubular shaft, cover has silica tube, the built-in ultraviolet source of silica tube; The blade of 6 ~ 10 identical axial placements is set in the cone drum cavity, and these 6 ~ 10 blades evenly distribute along the circumferential direction of the cross section of cone cylinder, the outer end of each blade is the inwall of affixed cone cylinder all, the inner of each blade all to the silica tube place extend and and the silica tube outer wall between the distance of 2 ~ 4cm is arranged; On cone cylinder medial surface, on the medial surface of end socket and on blade outer surface all load TiO is arranged
2Coating; Axial lower part of cone cylinder is placed in pending waste water and rotates.
The invention has the beneficial effects as follows: cone cylinder continuous rolling can form thinner liquid film; Cone is conducive to liquid-flow and forms liquid film rather than water droplet; In the cone cylinder, the blade of radial installation can enlarge liquid film area; Ultraviolet source is placed in cone cylinder inside can guarantee the exciting light waste of not running off, and improves degradation efficiency.Evidence: for containing the waste water of gold orange II concentration at 75mg/L, the clearance that continues processing 3h water outlet gold orange II afterwards through this equipment reaches 92%.
