Description

A kind of floatation type photocatalytic plate for water surface organic matter degradation

Technical field

It the utility model is related to a kind of photocatalytic reaction device, and in particular to a kind of for water surface organic matter degradation Floatation type photocatalytic plate, especially for the organic matter swum on the water surface, such as treatment and purification of oily waste water etc., have compared with Good photocatalytic Degradation, belongs to water body purification and field of environment protection.

Background technology

For floating on the organic pollution on water body, such as oily waste water, Physical, bioanalysis and chemistry can be used Method is handled, and Physical is simply efficient, but its processing is often not thorough enough；Bioanalysis degraded is thorough, but is only applicable to low dense Spend the processing of oily waste water；Chemical method also includes many methods, such as chemical-agent technique, flocculence, photocatalytic oxidation etc., The use of reagent is likely to result in other pollutions wherein in chemical-agent technique, and the principle of flocculence is mainly the work such as adsorption bridging With, it is therefore an objective to macromolecule organic is formed, pollutant is quickly and efficiently removed, but common molysite and aluminum salt flocculant can be made Into the secondary pollution of water body, and the cost of high polymer coagulant is too high, so practical application has some limitations, and light Catalysis technique has the advantages that of low cost, non-secondary pollution, organic pollution that can be preferably in degradation water.

For the photocatalysis technology of oily waste water, the suspended particulate of Nano grade can be used and configure ultraviolet source, or Person uses cenosphere or expanded perlite as carrier, makes float type TiO₂Photocatalyst granular, using ultraviolet source or Person's solar source degrades oily waste water, and this photocatalysis method prepares photocatalytic particle complex process, and light needs elder generation Row is irradiated to photocatalyst surface, photocatalysis then could be produced, but if illumination is mapped to the dirt for being adsorbed in photochemical catalyst Contaminate on thing, since the reflection to light of pollutant, scattering etc. act on, cause the utilization ratio of light to reduce.

The main purpose of the utility model is to reduce the cost of manufacture of photochemical catalyst, the efficiency of light is efficiently utilized, using saturating The glass plate of light is carrier, and light enters from glass plate side, the photochemical catalyst of glass plate opposite side is directly passed to, so as to reduce Transmission of the pollutant to light such as stops at the effect, improves the transmission efficiency of light, reduces cost of manufacture and economical operation cost.

The content of the invention

The purpose of the utility model is to overcome the deficiency of existing photocatalysis technology, uses the glass plate of printing opacity as photocatalysis The carrier of agent, to reduce cost, photocatalysis layer is set in the side of glass, and opposite side sets light source to enter, in this way, then light is straight The glass for connecting printing opacity passes to photochemical catalyst, improves the transmission efficiency of light, while cause photocatalysis glass using floating ball device Glass plate is bubbled through the water column, so as to carry out photocatalytic degradation to the organic matter of water surface.

The purpose of this utility model is achieved through the following technical solutions：Applied using sol-gal process, dip-coating method, rotation The physical method such as the chemical methodes such as embrane method or vacuum vapour deposition, magnetron sputtering method is in high temperature resistant, the high strength glass of resisting breakage Side form photocatalysis layer, glass uses rectangular or square structure, opens up the circular hole of perforation in the corner of glass so that gas The stud that floating device can be carried by it is installed in circular hole, and is consolidated in photocatalysis by gasket, nut and cap-type nut On glass, by the way that the size of buoyancy can be adjusted to floating ball device water filling, so that photocatalytic plate swims in water surface.

Photocatalytic plate as described above, its floating ball device top are equipped with hollow stud, and there are water filling port, lower part in stud upper end Connected by bracing means with hollow floating ball, bracing means is hollow circular cylinder structure, and floating ball device can pass through water filling port To floating ball water filling, so as to adjust the buoyancy in water of floating ball device, photocatalytic plate is adjusted in the position of the water surface with this, is floated Increase gasket, nut and cap-type nut after the circular hole that the stud of ball device can be penetrated through by photocatalytic plate and be fixedly arranged at photocatalytic plate On, cover type nut plays the sealing function to floating ball device.

Photocatalytic plate as described above, floating ball device and gasket, nut, cap-type nut can use unified material system Make, such as the material such as polytetrafluoroethylene (PTFE), plastics, stainless steel, floating ball device can use a casting process to make.

TiO can be selected in photocatalytic plate as described above, photocatalysis layer₂Or ZnO coatings, it also can be selected and changed by doping The photochemical catalysts such as property, noble metal loading.
