Abstract
The utility model discloses a photocatalytic water purification device, and aims to overcome the maintenance inconvenience of prior purification devices when the photocatalyst is aged. The device comprises a reaction bed (4), a transparent jacket (3) positioned in the reaction bed (4), and an ultraviolet light source (5) arranged in the jacket, wherein the inner wall of the reaction bed has an inner cylinder (8) which detachably connects with the reaction bed by the sleeving method; the surface of the inner cylinder (8) is coated with a titania film as the photocatalyst. With the structure, the inner cylinder can be directly replaced when the photocatalyst is aged, so the maintenance is simple and has light work load.
Description
Technical field
The utility model relates to a kind of quality purifying device for water, especially a kind of photochemical catalysis water purification equipment.
Background technology
The method and apparatus of existing purification of water quality is a lot, as purifying water with method such as ultraviolet ray, electronics, high frequency magnetic field, membrane filtration and technology, uses these method and apparatus to purify water, otherwise purify not thorough, or working cost height; The also device that purifies water of the optically catalytic TiO 2 of useful suspending phase, but because the technology that the suspending phase optically catalytic TiO 2 purifies water exists the use cost height, the titanium dioxide optical catalyst that suspends in water is difficult to reclaim, and easily causes secondary pollution problems to be difficult to be accepted by the user always; Also has the device that purifies water that the titanium dioxide optical catalyst of stationary phase is fixed on reaction bed, but there is such shortcoming in this device, that is: the titanium dioxide optical catalyst of stationary phase must be with parts the heaviest in the equipment after aging: renovate plated film again after the reaction bed dismounting, waste time and energy, inconvenient maintenance, especially contaminated when serious in water quality to be clean, the user can't bear the heavy load especially.
Summary of the invention
Technical problem underlying to be solved in the utility model be intended to provide a kind of can convenient for maintaining and the photochemical catalysis water purification equipment of maintenance.
According to the utility model; a kind of photochemical catalysis water purification equipment; comprise reaction bed; place the transparency protected sleeve pipe in the reaction bed and be built in the interior ultraviolet source of this sleeve pipe; the inwall of described reaction bed also has and its belled inner core; the surface of described inner core is coated with titanium deoxid film as photocatalyst, it is characterized in that: the socket mode of reaction bed and inner core is detachable.
After adopting the utility model, because the belled inner core can be dismantled in reaction bed, photocatalyst when the inner core surface: catabiosis takes place because of life-time service in titanium deoxid film, when having influence on effects of purification quality, after this inner core can being pulled down, direct replacement becomes the new inner core of a standard or former inner core plated film again can be continued to use, guarantee the effect of purification of water quality, and do not need to dismantle comparatively speaking comparatively heavy reaction bed, thereby the maintenance of entire equipment and maintenance work amount are reduced greatly, very easy to use.
The purpose of this utility model, feature and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model photochemical catalysis water purification equipment;
Fig. 2 is the structural representation of the inner core among embodiment of the utility model photochemical catalysis water purification equipment.
Concrete embodiment
With reference to Fig. 1, photochemical catalysis water purification equipment of the present utility model, comprise: reaction bed 4, place the transparency protected sleeve pipe 3 of reaction bed 4 central authorities and be built in ultraviolet source 5 in this protective casing 3, this ultraviolet source can be a ultraviolet light that can send efficient UV-light, the effect of transparency protected sleeve pipe 3 is under the prerequisite that guarantees printing opacity, avoid ultraviolet light 5 directly to contact with sewage, generally speaking, this protective casing can use quartz glass sleeve to make, certainly, use other printing opacities, waterproof, it is also passable to be difficult for adhering to the sleeve pipe that the material of impurity makes, protective casing places the central authorities of reaction bed 4 can be radiated on the catalyzer titanium deoxid film equably for the UV-light that ultraviolet light is sent, avoid because uneven irradiation had both influenced the effect of purification of water quality, also can make the appearance of photocatalyst uneven aging, the work-ing life of unnecessary reduction inner core 8; The inwall of described reaction bed 4 also has and its belled inner core 8, the surperficial plated with photocatalysis agent of described inner core 8: titanium deoxid film, its mode of connection is detachable, such as can being that standing screw 6 by as shown in fig. 1 connects inner core 8 and reaction bed 4, install simply, also be convenient to both partition; Also can when making inner core 8, its shape be made the form that matches with the inwall of reaction bed 4, directly be plugged in the reaction bed, be the convenience of socket, dismounting, also can be further leave flange face 81 at an end of inner core 8.The surface of described inner core 8 is coated with the layer of titanium dioxide film as photocatalyst, this layer titanium deoxid film is under the irradiation of the efficient UV-light that ultraviolet light 5 sends, electron absorption luminous energy on its valence band and being excited, have that very strong active electronics--the hole is right thereby can produce, form redox system.These electronics--hole is to moving to titanium dioxide fixedly behind the film surface, with dissolved oxygen and H
2O has an effect, final hydroxyl radical free radical (OH) and the super-oxide ion that produce with highly chemical oxidation activity, and hydroxyl radical free radical (OH) is a strong oxidizer, it can be CO with the organism permineralization
2And H
2O, it has broad spectrum to organic oxygenizement, and organic reaction rate constant is generally between 108～109mol-1s-1.The electron affinity of hydroxyl radical free radical (OH) is attacked the organic molecule position of high cloud density easily generally all than higher, forms easily the further intermediate product of oxidation.Therefore, adopt the utility model can remove various dissimilar organic pollutants in the waste water, and, also can utilize this method effectively to remove as chloroform, polychlorobiphenyl, organo phosphorous compounds, polycyclic aromatic hydrocarbons etc., thereby reach the purpose that purifies water with the material that other method is difficult to remove.
Use the utility model after for some time, because the titanium deoxid film as catalyzer tends to take place catabiosis, influence the effect of purification of water quality, especially when water quality is bad, aging faster, at this moment, as long as will be coated with the inner core 8 of this film pulls down, again plated film, or the plated film sleeve of changing another standard can continue to use, because that the inner core 8 in the utility model does not need to make is very thick and heavy, thereby remove just can be very light and handy, so just simplify the maintenance work of equipment greatly, also improved the service efficiency of entire equipment.
