Description
Technical field
The present invention is a kind of the have ultraviolet ray that improves sterilization effect and sterilizing unit of ozone, is meant especially a kind ofly to have the double helix water stream stroke and can make ozone and the dissolving of water thorough mixing and make water fully shine ultraviolet ray with the ultraviolet ray of reaching the improvement sterilization effect and the sterilizing unit of ozone.
Background technology
Traditionally in the water treatment device that generally uses, basically be to utilize a mercury quartz burner that it is exposed in the contaminated water, or an airflow (air stream) is exposed to make airborne oxygen produce ozone in the radiation of mercury quartz burner, the air (ozonated air) that makes these ozonize again with desire in addition clean polluted water and carry out mutual mixed dissolution.
The producing method of ozone mainly contains electrion and mercury quartz burner irradiation dual mode.Aspect ultraviolet lamp tube irradiation generation, the ultraviolet ray that general mercury quartz burner is produced all contains 254 nanometers, and (nano meter is nm) with two kinds of wavelength of 185 nanometers.Near the ultraviolet ray of wavelength 185 nanometers is ozoniferous main wave band, can utilize this principle to produce ozone to be used for sterilization in water.
Ultraviolet ray and ozone are two kinds of very common bactericidal mechanisms.Wavelength is near the ultraviolet ray the 254nm (nanometer) in case with after microorganism contact, and ultraviolet ray is easy to by the protein in the microorganism, DNA and RNA absorption.After this ultraviolet ray of material absorbing such as protein reaches certain intensity (dosage), can cause membranolysis, and then cause necrocytosis.In addition, high to making cell dead immediately even if the dosage of institute's irradiation ultraviolet radiation does not have, even but also be enough to cause microorganism to lose the ability of growing and be unlikely to make the people sick than the irradiation of low dosage.
The ozone aspect, ozone itself is a kind of very strong oxygenant basically, and ozone is in case with after microorganism contact, and its germ-resistant mechanism comprises: 1. directly destroy cell walls, cause the composition of cell to outflow and make necrocytosis; 2. the free radical by product that is produced after the ozone decomposition also can cause necrocytosis with cytosis; 3. destroy the composition structure of nucleic acid (nucleic acid); 4. interrupt bond, cause polymer to separate.
Ultraviolet ray and ozone itself all have sterilizing ability, yet in the use, particularly be applied in tap water sterilization aspect and but cut both ways, and the consideration of equipment determine the foundation of actual effect quality especially.To produce wavelength be that the ultraviolet ray of 254nm comes the water irradiation with direct sterilization by mix and use mercury lamp with near shortwave (the wavelength 185nm) ozone that uviolizing was produced and water, that is so-called double mode (dual mode), tool is strengthened sterilizing ability.
In design, generally be that the ozone that quartz burner is produced is constantly extracted out, and inject pending water, make ozone carry out preliminary sterilization and mixed with ozone contain ozone water, that is be imported into former ozoniferous ultraviolet lamp tube outer wall, and then make that to contain ozone water be the ultra-violet sterilization of 254nm with the wavelength, to strengthen sterilization effect, reduction simultaneously is ozone partly, makes last effusive water not only by thorough sterilization, and remove the excessive remaining ozone that hinders HUMAN HEALTH.
In the prior art, though relevant patent has solved the generation and injection water of ozone, and merge system design problem such as ultra-violet sterilization, yet the action time that these patents but lack effective prolongation ultraviolet irradiation time and prolong ozone, and strengthen ozone and the basic sterilization requirement of water thorough mixing dissolved.
Ultraviolet ray mainly is to depend on the height of dosage and the length of duration of contact with the sterilization effect of ozone.The ultra-violet sterilization aspect can take into account so-called ultraviolet dosage (UV dose) problem usually.Ultraviolet dosage is meant that uviolizing rate (fluence rate) is multiplied by irradiation time (irradiation time).It must be that enough sterilization intensities and long as far as possible irradiation reaction times will be arranged that ultraviolet ray will reach certain sterilizing ability.The commercially available ultraviolet lamp tube that general sterilization is used be in that it all can reach requirement at the beginning of using aspect the intensity, comes water shone and reaches sterilization effect to see through silica tube.The ultraviolet lamp tube of this moment still depends on the length of reaction cavity its effective duration of contact no matter be to turn on light in 24 hours or controlling fluorescent tube by switch opens or closes, and the contact length of general commercially available prod is about 30cm.
Though some prior arts is described the natural helical effect of utilizing current the to backwash irradiation time that extends, it prolongs effect also only in 1.5 times, is equivalent to the contact length about 40cm.
Ozone sterilization is identical with ultra-violet sterilization, and its sterilization effect is general to adopt so-called CT value to assess.So-called CT value then be meant the concentration C value and duration of contact the T value product.Same, make the ozone generation certain germicidal efficacy that ozone is had fully and water duration of contact and mutual mixed dissolution time.
The general ozone that manufactures by quartz burner, concentration is compared to so-called corona discharge (Corona discharge), and its concentration is not high, is less than 20 times approximately.In view of this, increasing duration of contact will be unique improved procedure.The present invention, is able to descend along the pipe spiral after making ozone and water mixing by design cleverly, and its stroke distances surpasses 120cm, about 3 to 4 times compared with the time lengthening of prior art approximately.And after flowing out contain ozone water see through spiral tube pitch (pitch) and and sleeve between accommodation space reversely up be back to outlet (double helix water stream stroke), on the way again by the abundant irradiation-sterilize of ultraviolet ray.
Generally speaking, the present invention uses double mode sterilization process and design double helix water stream stroke, can effectively prolong ozone and ultraviolet sterilizing time, to reach sterilization effect that prior art is beyond one's reach.
Aspect water treatment, relevant patent United States Patent (USP) 5266215 as shown in Figure 1, " the water purification unit " of Engelhard (Water purification unit) and United States Patent (USP) 5540848, " being used for the unitary filter material conservator of water purification " of Engelhard (Filter retainer for waterpurification unit), with desire clean water in the mode that causes whirlpool 402 around ultraviolet source of radiation 401, with remove in the water bacterium and to the HUMAN HEALTH harmful microorganism.
United States Patent (USP) 6245229B1 and for example shown in Figure 2, " using the some water treatment system " (the point-of-use water treatment system) of Kool et al., its also be with desire clean water in the mode that causes whirlpool 412 around ultraviolet source of radiation (not shown), to remove in the water and bacterium and to the HUMAN HEALTH harmful microorganism.But these patents are all simple spiral water column design, and it is very limited that it is exposed to ultraviolet radiated time.
Again, United States Patent (USP) 4273660 as shown in Figure 3, " using the cleaning of ozone and ultraviolet water to handle " (the purification of water through the use of ozoneand ultraviolet light) of Beitzel, with the water of desiring traditionally to be handled 432 directly be immersed in quartz burner 431 around, there is no any helical design, so its sterilization effect is also very limited.
In addition, United States Patent (USP) 5707594 as shown in Figure 4, " the pathogenic bacteria Controlling System " of Austin (Pathogen control system), its be used for fluming water with around the iron around the quartz burner 421 not the spiral hydraulic pipe 424 of dragon (teflon) system itself can make ultraviolet yield of radiation decay and can't reach thorough germ-resistant target, and the not imperial spiral hydraulic pipe of making 424 of iron is oversize, involve great expense, be not inconsistent the cost demand.
For this reason, how to prolong the stream course in the water treatment, so that flow into ozone in the water and the dissolving of water thorough mixing in order to do the sterilization effect that promotes ozone, and make water fully shine ultraviolet ray to promote ultraviolet sterilization effect, just become the present invention and lay siege to improved target.

Embodiment
As shown in Figure 5, a kind of the have ultraviolet ray of improvement sterilization effect and the sterilizing unit 200 of ozone of the present invention, it is a part that belongs to a water treatment system.This water treatment system is made up of a filtration unit 100, a sterilizing unit 200, an ozone suction apparatus 300.
This has the ultraviolet ray of improvement sterilization effect and the sterilizing unit 200 of ozone comprises a sterilization tube 202, a mercury quartz burner 210, a silica tube 208, an ozone pneumatic tube 216, a spirrillum hydraulic pipe 215 and a sleeve 217.
As Fig. 5, shown in Figure 7, sterilization tube 202 is the shell of this sterilizing unit 200, and it contains a water-in 204 and a water outlet 206; And mercury quartz burner 210 (Fig. 6) is the center that places this sterilizing unit 200, is used for after switching on producing ultraviolet ray, and it contains wavelength is can make air produce ozone about 185nm and wavelength is to be used for sterilization and destroy redundant ozone about 254nm.In other embodiments, the water-in of this sterilization tube and water outlet can be any suitable positions that is positioned at this sterilization tube, and the number of this mercury quartz burner is not limited to one, can be adjusted according to actual needs.Again, sterilization tube 202 is made by plastics, stainless steel or glass.
As Fig. 5, Fig. 6, shown in Figure 7, silica tube 208 is a translucent tube, can see through wavelength and be the ultraviolet ray about 254nm, but can stop that wavelength is the ultraviolet ray about 185nm, and this silica tube 208 is the peripheries that are placed in this mercury quartz burner 210, therebetween for comprising an accommodation space 219 of air.And the ozone amount that air is produced when wavelength is the uviolizing of 185nm wavelength around is a uviolizing institute destructive ozone amount about 254nm greater than wavelength, so its clean ozone amount can increase because of ultraviolet irradiation.
Secondly as Fig. 5, shown in Figure 6, ozone pneumatic tube 216 is to be inserted in the accommodation space 219 of 208 of this mercury quartz burner 210 and this silica tubes.One end of this ozone pneumatic tube 216 is to be connected to ozone suction apparatus 300, and its other end has an inlet mouth 220 that is exposed in this accommodation space 218, air in this accommodation space 219 can be sucked through the low pressure that suction produced of this ozone suction apparatus 300 of ozone mat that uviolizing produced, and then deliver to this ozone suction apparatus 300.This ozone pneumatic tube 216 is the opaque pipe that can not see through ultraviolet, so though be exposed to and also can not have influence on the interior ozone concn of this ozone pneumatic tube 216 under the irradiation of ultraviolet.
Fig. 5, shown in Figure 7 and for example, spirrillum hydraulic pipe 215 is surrounded on around this silica tube 208 in a spiral manner, the one end is connected to water-in 204, and the other end comprises a water outlet 221, can from this ozone suction apparatus 300 and via the water that comprises ozone of water-in 204 input in addition uniform mixing to reach sufficient ozone sterilization effect.But this spirrillum hydraulic pipe 215 is the opaque pipe that can not see through ultraviolet, so ultraviolet can not have influence on the ozone sterilization effect of water ozoniferous in this spirrillum hydraulic pipe 215.Again, spirrillum hydraulic pipe 215 is made by plastics or glass.In addition, current are limited in the hydraulic pipe of the about 6mm of the thickness of pipe, cause peripheral uitraviolet intensity decay to make the not good shortcoming of sterilization effect to improve because of too thick.
Fig. 5, shown in Figure 7 and for example, sleeve 217 is to be placed in the periphery that is surrounded with this spirrillum hydraulic pipe 215, the one end is closed in the top of sterilization tube 202, and the other end is the opening 224 towards sterilization tube 202 bottoms.It can make the water outlet 221 effusive water by this spirrillum hydraulic pipe 215, mat follows its spirrillum hydraulic pipe 215 and goes downstream and backwash flow that the surging force of these sterilization tube 202 bottoms is produced according to the thin direction of arrow 225 of black according to the thin direction of arrow 223 of black, in these spirrillum hydraulic pipe 215 each pitch spaces 222 in this sleeve, along these spirrillum hydraulic pipe 215 outsides, and sail against the current according to the thick direction of arrow 227 of grey around these silica tube 208 outer walls; It is ultraviolet about 254nm that current on the way then can fully be exposed to wavelength that this mercury quartz burner 210 (Fig. 5, Fig. 6) gave off and penetrated these silica tube 208 tube walls, reaches sufficient ultra-violet sterilization effect.Simultaneously,, can lower the excessive ozone that hinders HUMAN HEALTH in the above-mentioned water ozoniferous behind ozone sterilization through the irradiation of ultraviolet, after the water outlet 206 of sterilization tube 202 flow out for drinking.
Not make by dragon (teflon), stainless steel or glass by plastics, iron for sleeve 217.This duplex shape current design its current flow process length overall can be equivalent to 4 times irradiation time up to more than the 120cm, has improved sterilization effect greatly.
In other embodiments, one end of this sleeve 217 still is closed in the top of sterilization tube 202, but the other end then is closed in the bottom of sterilization tube 202, so this sleeve 217 itself can replace this sterilization tube 202 as these sterilizing unit 200 shells, thereby this sterilization tube 202 can be removed and need not.
In conjunction with the sterilizing unit of ultraviolet ray with double mode (the dual mode) of the sterilizing function of ozone, design by double helix water stream, reach the stream course lengthening, and the lengthening of stroke means the time lengthening of current contact uviolizing, mean also simultaneously that rate of ozone dissolution increases, to strengthen whole sterilization effect.
After current are brought into via spiral tube, by between the outer pitch of spiral tube and spiral tube be enclosed within its telescopic interlayer on every side adverse current and get back to water outlet.The caliber of (silica tube) outer (sleeve pipe) pipe was poor in this design helped water layer thickness is constrained to, and the strength retrogression of uviolizing will be more not obvious thus, and sterilization effect is also better.
The design of helix is constantly turned round current and is stirred inside and outside pipe, make the mixed effect of ozone and water more abundant.
By being the sleeve pipe of material with glass, native system can become a transparent design, and the user can know sees inner water quality treatment situation, can accomplish the target of water treatment quality transparence.
Ultraviolet ray separates with the sterilizing function of ozone; Can carry out ozone sterilization when ozone is carried in hydraulic pipe, and water can be exposed to ultraviolet irradiation when adverse current is turned round outside hydraulic pipe and carry out ultra-violet sterilization once more.
The above is preferred embodiment of the present invention only, is not to be used for limiting scope of the invention process.Be allly to do impartial change and modify, be all the contained lid of claim of the present invention according to the present patent application claim.
