Description
Technical field
The relevant a kind of water-purification plant of the present invention refers in particular to the ultraviolet water purification device that a kind of ozone that utilizes ultraviolet ray and produced by the uviolizing air and photocatalyst technology are eliminated and purified the bacterium in the water.
Background technology
Existingly kill the device of the germ in the water,, ultraviolet lamp is housed above in an encloses container as the product of Shanghai No. 7 Light Industry Machinery Factory with ultraviolet ray (be called for short UV) irradiation.Below ultraviolet lamp, the two ends of container are equipped with water-in and water outlet respectively, and water flows into from water-in, after uviolizing, flow out from water outlet, this structure is only utilized ultraviolet radiation sterilization, and teratogenesis, carcinogenic, mutagenic organism are difficult to remove in the water.
At above defective, produced a kind of terms of settlement, as patent 91215571.X, it has promptly disclosed a kind of novel water purifying device, this device comprises a sealed vessel, and water is housed in it, and ultraviolet lamp is set above water body, have air in certain amount between water body and the ultraviolet lamp, utilize ultraviolet germicidal action to reach the ozone that is produced by the uviolizing air and simultaneously water body is purified.Yet because set ultraviolet lamp is in the top of water, only some can directly play germicidal action to water in ultraviolet ray; And the ozone that produces only works on the surface of water, if water body is thicker, then can not subterranean water purify.The efficient that how to improve the purification of ultra-violet sterilization and water becomes the industry problem demanding prompt solution.
Summary of the invention
The objective of the invention is to propose a kind of ozone that can use ultraviolet ray simultaneously and produce by the uviolizing air and the ultraviolet water purification device that cooperates the photocatalyst technology to come sterilization and purify waste water.
The object of the present invention is achieved like this: a kind of ultraviolet water purification device, at least comprise reactive tank, it is characterized in that being provided with in the reactive tank exposure tube and a circulating cooling pipe, in the exposure tube is the low pressure discharge pipe, one end of one inlet pipe and an escape pipe stretches in the above-mentioned exposure tube, have the photocatalyst sheet group that is coated with photocatalyst material around the exposure tube setting, under action of ultraviolet ray, this sheet group plays germicidal action to water.The other end of described escape pipe links to each other with an end of a circulating cooling pipe, is connected with the air dispelling device that gas dispersion can be sent again, and the other end UNICOM of circulating cooling pipe is in above-mentioned inlet pipe, and described circulating cooling pipe is located in the reactive tank.
The present invention also has following feature, is provided with a time-delay pipe between described air dispelling device and the reactive tank.Described escape pipe links to each other with an end of a circulating cooling pipe, and the other end of circulating cooling pipe is parallel to above-mentioned inlet pipe; And discharge tube can send the ultraviolet ray that wavelength is lower than 290NM.
The present invention also has following feature, and on the described water inlet pipe or the appropriate location of reactive tank is provided with the inlet pipeline that can import oxygenant.Described oxygenant is a chlorine, or ozone or hydrogen peroxide, or hypochlorous acid, or Fenton reagent.
Compared with prior art, the invention has the beneficial effects as follows: the air that is mixed with ozone enters exposure tube through circulating cooling pipe again once more after escape pipe output, can utilize the round-robin freezing air that discharge tube is cooled off, and circulation to enter the ozone concn that produces through repeatedly uviolizing higher.Discharge tube can send the ultraviolet ray of two kinds of wavelength, for utilizing the direct sterilization of ultraviolet ray and utilizing the ozone sterilization that produces all can produce preferable effect.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
See also shown in Figure 1ly, it is the synoptic diagram of an embodiment of the utility model ultraviolet water purification device.This ultraviolet water purification device has reactive tank 1, has a certain amount of water in the reactive tank 1, perpendicular to the water surface exposure tube 2 is set in the water.The air pressure discharge tube 21 of loweing (only showing one among the figure) is installed in the above-mentioned exposure tube 2, and this air pressure discharge tube 21 of loweing can emit wavelength be the ultraviolet ray of 253.7NM and 184.9NM.Exposure tube 2 is to be made by transparent material, can make uviolizing that low pressure discharge pipe 21 sends on water body, because exposure tube 2 is arranged at water body inside, so ultraviolet ray can be shone in water body to maximum area, plays preferable sterilization effect.One end of one inlet pipe 5 and an escape pipe 4 stretches in the exposure tube 2, and air produces ozone by in the inlet pipe 5 input exposure tubes 2 through after the uviolizing, and the air that is mixed with ozone is by escape pipe 4 outputs, and an end of above-mentioned escape pipe 4 is connected with air dispelling device 15.Be provided with a time-delay pipe 14 between air dispelling device 15 and the reactive tank 1.The air that is mixed with ozone disperses to enter in the time-delay pipe 14 through air dispelling device 15 backs.This time-delay pipe 14 is for be provided with the duration of contact that prolongs ozone and water, in the hope of the decontamination effect improving preferably that has to water.Behind time-delay pipe 14, enter reactive tank again.With reference to Fig. 2, and Fig. 3, in order to strengthen the sterilization effect in the reactive tank, have the TiO of being coated with around exposure tube 2 settings
2 Photocatalyst sheet group 3, under action of ultraviolet ray, this sheet group plays germicidal action to water.Described photocatalyst sheet group 3 comprises some outer disks 34 of exposure tube that are placed in, and is inserted with some TiO of being coated with on the disk 34
2Photocatalyst sheet 30.The whole TiO that is coated with
2 Photocatalyst sheet group 3 can in reactive tank 1, be that rotate at the center with water with exposure tube 2.At some TiO that are coated with
230 of photocatalyst sheets can insert some cleaning brush sheets 31 and be connected to the outside surface of exposure tube 2.Along with being coated with TiO
2The rotation of photocatalyst sheet group 3, the hairbrush 33 before the cleaning brush sheet 31 are connected to exposure tube 2 appearances, so that exposure tube 2 is scrubbed cleaning.Catalyst sheet 30 on each sheet group 3 is in the same place by a circular boop 32 button hoops with cleaning brush sheet 31.
Above-mentioned inlet pipe 5 enters positions in the exposure tube 2 and will be higher than escape pipe 4 and enter position in the exposure tube 2, because the density of ozone will be far longer than air, so the bigger ozone of density is sunken to the below of exposure tube 2, and the output of ozone is convenient in such setting.One circulating cooling pipe, 8 one ends are connected in escape pipe 4, and the other end is connected in inlet pipe 5, and so, then a part will enter raying in the exposure tube 2 once more through the air that is mixed with ozone after the uviolizing, and the concentration of ozone can further strengthen like this.
Above-mentioned reactive tank 1 has water inlet pipe 11 and rising pipe 12, simultaneously with the inlet pipeline 13 of water inlet pipe 11 input oxygenants (but chlorine) in parallel, because chlorine sensitization after UV shines in water, has the effect of stronger promotes oxidn.Equally also can import the pipeline of chlorine with escape pipe 4 in parallel.Described oxygenant is a chlorine, or the ozone hydrogen peroxide, or hypochlorous acid, or Fenton reagent.
See also Fig. 1 and shown in Figure 4, the bottom of reactive tank is provided with stationary installation 7, and the upper surface of this stationary installation 7 has a plurality of connecting holes 71, and correspondence has union lever 26 in the bottom of exposure tube 2 therewith.Union lever 26 inserts in the connecting hole 71, can make exposure tube 2 firm in reactive tank 1.
In addition, the oxygenant as chlorine and so on also can directly feed in the reactive tank 1.
Coatedly on the described photocatalyst sheet also can be TiO
