Abstract
The invention provides a device for photolytically desorbing (regenerating) activated carbon, which comprises a front part and a back part. The front part adopts a well-known filtering and absorbing device, which can be used for filtering out massive solid matter. The back part consists of the activated carbon which is multi-layered, thin layer-shaped, and is mixed with nano-photocatalyst. The front part and the back part are arranged with each other at intervals, an ultraviolet light pipe axially penetrates through the front part and the back part, and an outer layer is packed with a specular reflector. When residual tiny matter after purifying by the front part such as volatile compound, bacterium, toxic gas and smoke passes through, the residual tiny matter can be absorbed layer by layer, under the irradiation of the ultraviolet light, the residual tiny matter can be quickly cracked to be water and carbon dioxide after photocatalysis, and the carbon dioxide is desorbed (regenerated), and absorbed; and adsorption and desorption can be continuously carried out, so that the long-acting use of the activated carbon can be realized.
Description
Technical field
The present invention relates to active carbon desorption (regeneration) device, the desorption apparatus of particularly accomplishing automatically.
Background technology
Existing activated carbon, in use as easy as rolling off a log saturated because of having adsorbed various small materials, thus lost efficacy, in order to make its regeneration, current use boiling, original and inconvenient method such as be exposed to the sun, so in most cases, activated carbon all is disposable use.
But activated carbon still has unique function at small materials such as adsorb volatile compound, germ, smog, gas toxicants, therefore new technological means is provided, and makes it possess power of regeneration, realizes long-acting use, just seems very important.
Summary of the invention
Through analyzing, we find, in use in the past, no matter material classification and size all let activated carbon absorb, and pm such as a large amount of is dust
10The material of class makes it saturated; This type material in the prior art; Can absorb completion with middle high efficiency filter layer or static fully; Adsorb and leave small materials such as extremely unmanageable volatile compound, germ, smog, poisonous gas for activated carbon, utilize above material to be made it become CO like this after the categorizing selection by the ultraviolet photodissociation
2With the characteristic of water, be equipped with nano-photocatalyst simultaneously, quicken its reaction speed, accomplish and quicken photodissociation, and make the automatic desorption of activated carbon, realize the purpose of long-acting use.
Photodissociation desorption activated carbon device of the present invention; It is characterized in that: it is to be made up of front and back two parts; Forward part is known middle high efficiency filter layer or electrostatic adsorption device, and the rear section is by the activated carbon layer that is mixed with photochemical catalyst, and ultraviolet light pipe and mirror board shell constitute.
In the described photodissociation desorption activated carbon device, the activated carbon that is mixed with nano-photocatalyst is made as some thin layers, and they alternately.
In the described photodissociation desorption activated carbon device, quartz burner is through between the activated carbon thin layer, and each aspect all has illumination, and is different because of volume, can be that a fluorescent tube also can be several fluorescent tubes.
In the described photodissociation desorption activated carbon device, the afterbody of activated carbon is established a terminal filtering layer, so that activated carbon shedding is long afterwards filtered.
The invention has the beneficial effects as follows: realized the automatic desorption (regeneration) of activated carbon, made the long-acting continuous use of its ability.Activated carbon is technical to have a positive effect to promoting.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Among the figure, the 1st, forward part, it is to be made up of known filter, the 2nd, rear section (being the photodissociation part), and the 3rd, mirror board, the 4th, terminal filtering layer, the 5th, be mixed with the activated carbon coating of photochemical catalyst, the 6th, quartz burner.
The specific embodiment
With reference to accompanying drawing the present invention is described further.After contaminant gases gets into the photodissociation desorption apparatus; Wherein micronic dust earlier down by anterior known filter or electrostatic adsorption device filter, gaseous materials such as volatile compound, bacterium, virus, poisonous gas and smog, at the rear portion one by one by the thin layer active carbon adsorption; Owing to be mixed with nano-photocatalyst in the activated carbon; Under the irradiation of ultraviolet light pipe, active carbon adsorption is owing to be mixed with nano-photocatalyst in the activated carbon; Under the irradiation of ultraviolet light pipe, these gaseous materials of absorption will be cracked into H
2O and CO
2, to drain with air-flow, activated carbon is accomplished regeneration by desorption, can continue to adsorb new gaseous contaminant, uses so continuously.Because the activated carbon of the photodissociation desorption apparatus that designs among the present invention is a multilayer, can let pollutant successively adsorb fully; Activated carbon be thin layer alternately, respectively the two sides in space is penetrated to guarantee ultraviolet, be mixed with photochemical catalyst in the activated carbon, when pollutant is adsorbed, under the irradiation of ultraviolet light, in the completion cracking fast of the surface of activated carbon.For energy-conservation, each layer activated carbon wrapped in the mirror board, add the high light reflection, effectively strengthen lytic effect.Be provided with terminal filter course, do not efflux with back activated carbon powder guaranteeing for a long time.
