In many technologies for removing the formaldehyde in air, photocatalysis oxidation technique is efficient, rapid, nontoxic, nothing two generally acknowledged at present
Secondary pollution, simple to operate, the more extensive removal technology of application prospect.The photo catalysis reactor of early stage be it is Floating, at most
Process object be waste water.With the development of science and technology, support type photo catalysis reactor is favored all the more by researcher.It is negative
The mentality of designing of load formula photo catalysis reactor is that catalyst is supported on reactor wall or suitable carrier, is allowed to
It is fixed in reactor, avoid the problem of photocatalyst separation is reclaimed and reused, but due to load capacity and catalyst in itself
Limitation so that reactor efficiency has much room for improvement.
TiO2With cheap and easy to get, chemical stability is high, and the selectively low advantage of contaminated object becomes photochemical catalytic oxidation
The most frequently used catalyst in technology.But TiO2Itself has some shortcomings and limits it and further apply again, and such as specific surface area is small
Adsorptivity is poor, and energy gap is larger, causes it poor to visible light utilization efficiency, light induced electron and hole life are extremely short, easily multiple
Close etc..The utility model is selected by the use of graphene as catalysis material by tectonic sieving and element, is designed a kind of new
Photo catalysis reactor system, with more efficient photocatalytic degradation efficiency.
Utility model content

Further, reaction subsystem is in cylinder, and some swash plates are distributed in the shape of a spiral in cylinder along axle.
This reactor selection LED daylight lamp is used as light source.LED daylight lamp light intensity is stronger, with specular removal and high-color rendering,
Low, the energy-conserving and environment-protective of heating, it is safe and reliable.Therefore the LED daylight lamp power of the utility model selection is 18W, and service life is
More than 50000h；Reflecting surface, swash plate and shell all select the aluminum material up to more than 95% to light reflectance.
Advantageous effect of the present utility model is：
1st, graphene film Rotating fields have huge specific surface area and conjugated structure, can adsorb a large amount of pollutants, be light
Catalytic reaction provides preferably reaction position, is conducive to the progress of reaction；The adsorptivity of graphene is stronger, can be first by contamination gas
Body is adsorbed around catalyst, then carries out light degradation；
2nd, the formaldehyde gas in room air flows in the shape of a spiral in reactor, when extending the stop in reactor
Between；
3rd, the concentration in flow process of the formaldehyde gas in room air is less and less, thus catalyst coated amount with from
The increase of light source distance and reduce, the energy can be saved, cost is reduced；
4th, this novel photocatalysis reactor can be not only removed to the formaldehyde gas in room air, also can remove other
Pernicious gas in air, is widely used；
5th, the raw material graphene of this catalyst is that the sludge produced using sewage treatment plant is prepared, and is both solved
The problem of sludge difficulty is put, has widened the market of sludge treatment, and the catalysis material of processing gas pollution can be made into again,
Position " resource " will be misplaced and reset again by being truly realized.
