Abstract
The utility model provides a photocatalytic water treatment device which mainly comprises a water treatment box, wherein a water inlet is arranged at the upper left end. Inner and outer active carbon tubes and an ultraviolet lamp are arranged inside. The inner and outer active carbon tubes are provided with electric contacts. Water treated is connected with a water outlet faucet on a base through a connecting pipe. The base is further provided with a control device for controlling the upper water treatment box to control. The device provided by the utility model has the beneficial effects that organic matters, heavy metal ions and harmful microorganisms such as bacteria and viruses and the like in water are removed while beneficial minerals to human body are maintained, and clean water can be efficiently and lastingly prepared; and the device is simple in structure, convenient to control and low in cost of treatment process.
Description
Technical field
The utility model relates to a kind of water-purification plant, relates in particular to a kind of photocatalytic water treatment device.
Background technology
Along with expanding economy, water pollutes serious day by day, in the tap water of conventional purifying treatment, contain not processed organism, heavy metal ion and bacterium etc., often be difficult to up to standard, particularly through produce behind the disinfection by chlorine have carcinogenic, lead=aberration inducing, the halogenated organic matters of mutagenesis etc., huge to the human injury, can only kill bacteria and boil, the objectionable impurities of eliminating other is not had very great help, thereby tap water must need could directly drink through behind the deep purifying.The water dispenser refining plant of selling on market at present mainly adopts following several method to carry out the deep purifying of tap water.A kind of is to remove organism and some deleterious metal ion in the water by the absorption of gac, but along with the carrying out of adsorbing, the adsorption of gac is tending towards saturated gradually and loses purification function.Another kind is a membrane filter method, usually ultra-filtration membrane and reverse osmosis membrane are made up the deep purifying that carries out tap water, ultra-filtration membrane can be removed suspended substance in the water, reverse osmosis membrane can be removed organism and metal ion in the water, though this way can prepare the higher tap water of purity, but film is polluted easily and is stopped up in operational process, and can have been removed the mineral substance of needed by human body.Also having a kind of is that charcoal absorption and membrane filtration combine and carry out tap water and purify, but the loss problem of blockage problem and mineral substance still can not solve.
The utility model content
The purpose of this utility model is to overcome weak point of the prior art, and a kind of photocatalytic water treatment device is provided.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of photocatalytic water treatment device, comprise pipe, ultraviolet lamp and base in water treatment case, gac outer tube, the gac, the left upper end of described water treatment case is provided with water-in, pipe and ultraviolet lamp from top to bottom are horizontally disposed with in water treatment case in gac outer tube, the gac, Guan Shangjun is equipped with and electrically contacts head in gac outer tube and the gac, be used for applying volts DS between two pipes, the tube-surface deposition has the TiO of photocatalytic activity in the described gac
2Film, base are fixed in the water treatment case bottom.
Further, described water treatment case links to each other with water tap with two outlet on the base by pipe connecting, and trip switch is arranged on the mid-way of base, electrically contacts head and ultraviolet lamp work in order to control.
The utlity model has following beneficial effect:
Photocatalytic water treatment device of the present utility model, semi-conductor TiO
2Under ultraviolet lighting, can produce electron-hole pair, photohole with strong oxidation can make that organism is decomposed into carbonic acid gas and water in the water, and can kill harmful microorganism in the water, as bacterium, virus etc., and can not remove mineral substance to the human body beneficial, the water of cleaning can be prepared high-efficient and lasting, and apparatus structure is simple, control is convenient, and treatment process is with low cost.
Description of drawings
Fig. 1 is a photocatalytic water treatment device front view provided by the utility model;
Nomenclature:
1: water-in 2: water treatment case 3: gac outer tube 4: pipe 5 in the gac: electrically contact 6: ultraviolet lamp 7: pipe connecting 8: base 9: water tap with two outlet 10: trip switch
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As a kind of embodiment of the present utility model, consult figure, a kind of photocatalytic water treatment device comprises: pipe 4, ultraviolet lamp 6 in water treatment case 2, gac outer tube 3, the gac, with base 8, water-in 1 is arranged on the left upper end of water treatment case, pipe 4 and ultraviolet lamp 6 from top to bottom are horizontally disposed with in water treatment case 2 in gac outer tube 3, the gac, all be equipped with on the pipe 4 in gac outer tube 3 and the gac and electrically contact 5, be used for applying volts DS between two pipes, pipe 4 surface depositions have the TiO of photocatalytic activity in the described gac
2Film, top water processing tank 2 links to each other with water tap with two outlet 9 on the base 8 by pipe connecting 7, and trip switch 10 is arranged on the mid-way of base 8.
During this device operation, tap water is flowed in the water treatment case 2 by water-in 1 by self pressure, and then manage between 4 in gac outer tube 3 and the gac by penetrating into, the mountain has applied volts DS manage 4 in gac outer tube 3 and gac between, the tap water between the pipe 4 stands dc electrolysis in gac outer tube 3 and the gac so be filled in, electrochemical reducting reaction takes place in the surface at outer tube 3, the micro heavy ion is reduced into metal and is deposited on the gac outer tube in the water, electrochemical oxidation reactions, oxidized decomposition such as reducing substances in the water such as organism take place in the surface at interior pipe 4.The TiO on pipe 4 surfaces in the gac
2Produce electron-hole pair after the UV-light that film absorption ultraviolet lamp 6 produces, photohole with strong oxidation will arrive the organism of managing 4 surfaces in the gac by diffusion and be decomposed into carbonic acid gas, water and other harmless inorganics, kill harmful microorganism such as bacterium, the virus etc. that may exist.Because applied positive potential on the pipe 4 in gac, light induced electron flows to gac outer tube 3 by external circuit under electric field action, reduced the compound of electronics and hole, has improved organism photocatalysis Decomposition efficient.Water after the processing is connected with water tap with two outlet 9 on being installed in base through pipe connecting 7, opens water tap with two outlet 9, just can obtain clean, safety, free of contamination tap water, and the trip switch 10 that base is provided with can control electrode and the work of ultraviolet lamp.
In sum; the utility model only is illustrated an embodiment of photocatalytic water treatment device; but the utility model is not limited thereto; it will be appreciated by those skilled in the art that under the situation that does not break away from the protection domain that claims of the present utility model put down in writing and to change arbitrarily and to revise.
