Description
Technical field
The present invention relates to ultraviolet fluid disinfection field, especially a kind of ultraviolet fluid treater.
Background technology
The reactor main cavity of traditional closed UV processor is generally the round shape of individual layer, it is provided with fluid inlet and outlet on barrel, the end installing quartz burner of cylindrical shell and sleeve pipe thereof, fluid from water-in perpendicular to ultraviolet lamp direction flow into cavity after uviolizing again vertical UV lamp direction flowed out by water outlet, radiation response is large by the fluid chemical field kinetic effect of medium, when particularly large discharge sterilisation housing diameter is large, this fluid chemical field kinetic effect strengthens, the UV exposure dose that in treater cavity, fluid receives is uneven, sterilisation effect is unstable, separately because its cavity length limits by quartz burner arc length, effective illumination length cannot be increased thus cannot cavity length be lengthened, therefore irradiation dose and flow all cannot increase, and limit the application of cylindrical process device in large discharge (a few kiloton-hundreds of thousands of ton per hour) fluid disinfection.
For improving the processing efficiency of traditional UV treater to adapt to the demand of various flow material sterilization, applicants have invented a kind of large-flow ultraviolet fluid sterilizer (patent No. 200810071135.1), it comprises the fixing device for installing of at least one uv sterilisation module and uv sterilisation module, each uv sterilisation module at least comprises a quartz burner, the main body of described fixing device for installing is that a joint can for the circular pipe being sterilized fluid and passing through, duct wall is arranged several uv sterilisation module open holess, one or two end face of fixing device for installing arranges the flow-stopping plate extended by the outer circumferential end faces center position of end face, flow-stopping plate place end face leaves for being sterilized the outlet pass that fluid passes through.Apparatus for ultraviolet disinfection is arranged on duct wall by this invention, then can arrange the installation quantity that duct length increases and decreases uv sterilisation module simultaneously at any time as required; The design of flow-stopping plate has also cushioned the pressure of water inlet to a certain extent, but it is different still to there is the UV exposure dose that in circular cylinder body, fluid each point is subject to, uneven problem of sterilizing.If change treater shape into rectangle, although ultraviolet lamp arrangement easily, when fluid is by rectangular cavities, fluid chemical field kinetic effect is little, and the UV exposure dose that treater inner fluid receives is even, but, rectangle treater is under equal conditions withstand voltage less, during sterilization uniform pressure fluid medium, its wall ratio cylindrical process device is much bigger, sets up a lot of reinforcing structure in addition, adds the manufacturing cost of treater.
In order to overcome above-mentioned technical problem, applicant improves again to existing ultraviolet fluid processor.Applicant's patent No. be 201220184654.0 Chinese patent disclose a kind of ultraviolet fluid treater of double-layer cavity wall structure, reactor is transformed into double-layer cavity wall structure by its defect for existing single cylinder structure of reactor, and the form that the circumscribed circle utilizing outer cylinder body to be inner barrel or dividing plate cut off forms cavity between interior outer chamber, this cavity makes in the fluid in inner barrel can be flowed into by the opening of described cavity, cavity between outer cylinder body, in can effectively reducing, the pressure that outer cylinder body is subject to, and in can reducing, the thickness requirement of outer cylinder body, save manufacturing cost.
But be through the use of for some time, applicant finds that the reactor in this patent still has problems.Outer cylinder body is that the circumscribed circle of inner barrel or dividing plate cut off in the reactor of (and adjacent two dividing plates have distance on outer cylinder body), although the cavity formed between interior outer chamber alleviates the pressure of inside and outside barrel to a certain extent, but it is discontinuous but be separated into several little cavitys due to the cavity that formed between interior outer chamber, and each position pressure of the internal outer chamber wall of each areola unbalanced, particularly the tie point place pressure-bearing of interior outer chamber wall is maximum, thus in use easily produces crack or welding seam leakage problem, simultaneously because the uv-radiation in each areola is uneven, local pollution concentration may be there is high, when the water body in cavity interlayer impacts by reactor water inlet and takes out of in cavity and enter internal layer cylinder, because the pollution concentration in each cavity is different, the water that each cavity is taken out of is by different for the contaminated water flow degree caused in internal layer cylinder, cause Systems Sterilizer uniform in effect poor, have impact on overall sterilisation effect further, in addition in Water Disinfection field, the low-pressure high-strength ultraviolet lamp of 1554mm length is suitable for due to its power level, supply has a good guarantee and is widely used, therefore the general low-pressure high-strength ultraviolet lamp selecting 1554mm length when manufacturing ultraviolet fluid treater, such outer chamber size is fixed, same, square cylindrical shell is connect in that patent in inner barrel circle, its size is also defined, when processing low discharge fluid disinfection, because the fluid water yield is little, ultraviolet lamp arrangement is few, it is short that fluid effectively irradiates flow process, irradiation dose is caused to reduce, and when adopting identical fluorescent tube, lamp tube array is few, then fluid just flows out from inner barrel without well mixing, hydrodynamical effect weakens, the irradiation probability that fluid accepts also significantly reduces, thus make the sterilisation effect of system to low discharge fluid poor.
The application is the improvement that the basis of the Chinese patent of 200810071135.1 and 201220184654.0 is made in applicant's patent No., with the effect efficiency of the bearing capacity and system that promote reactor, meets the fluid disinfection demand of various flow simultaneously.
Summary of the invention
The object of this invention is to provide a kind of rational in infrastructure, the ultraviolet fluid treater of fluid disinfection better effects if.
The technical scheme realizing the object of the invention is, a kind of ultraviolet fluid treater, comprise reactor body and some quartz burners and sleeve pipe thereof, reactor body two ends are respectively equipped with fluid inlet and fluid outlet, described reactor body comprises an inner barrel and an outer cylinder body, and described outer cylinder body coaxial sleeve is located at inner barrel outside; Form a continuous print pressure balance chamber between described inner barrel and outer cylinder body, described pressure balance chamber arranges opening at the first end near reactor fluid import, and the second end near reactor fluid outlet is closed; Inner barrel is fixedly connected with outer cylinder body by bracing frame, and on described inner barrel and outer cylinder body, correspondence is provided with quartz burner and sleeve pipe open holes thereof, and described quartz burner and sleeve pipe thereof to be arranged in open holes and to seal in contact position with inside and outside cylindrical shell.
In order to better sterilisation effect, the present invention can also do following improvement:
1, described outer cylinder body is cylindrical drum, and inner barrel is a cross section is the cylindrical shell of rectangle; Preferably, the cross section of described inner barrel is square.
2, coupling device is provided with outside the fluid inlet at reactor body two ends and fluid outlet.
3, described bracing or strutting arrangement is the ring-type bracing or strutting arrangement arranged around inner barrel, and described bracing or strutting arrangement is provided with water hole.
4, described bracing or strutting arrangement is the many ribs connecting inner barrel and outer cylinder body.
5, described inner barrel and the outer cylinder body length in water (flow) direction is equal.
6, described inner barrel is concordant with two ends of outer cylinder body.
The ultraviolet disinfection equipment of technical solution of the present invention is adopted to have the following advantages:
