Description
Technical field
The present invention relates to a kind of UV water treatment equipment that is used for water purification, Zhong Shui, following water.
Background technology
For bacterium class or pathogenicity bo protozoacide Cryptosporidium (Network リ プ ト ス Port リ ジ ウ system) to colibacillus etc. carry out sterilization, do not activate, UV water treatment equipment is popularized.Main machine is a UV-lamp in UV water treatment equipment, uses the discharge tube behind the inclosure mercury in Glass tubing usually.Make the dna damage of colibacillus etc. from the ultraviolet ray of this discharge tube irradiation, thus can sterilization, do not activate.In common UV water treatment equipment, its structure is: the protective tube of silica glass system is set between UV-lamp and processed water, and processed water does not directly contact with UV-lamp.
Because protective tube contacts with processed water; therefore if UV water treatment equipment work; inorganicss such as metal in the processed water (iron, manganese etc.) or calcium; perhaps organism is gradually to the surface attachment of protective tube, and blocked by these dirt settlings and can not fully arrive processed water from the ultraviolet ray that UV-lamp is sent.Adhere in order to suppress this, a lot of UV water treatment equipments possess the automatic cleaning mechanism based on the protective tube of physical methods such as slide.
But, also be difficult to remove fully dirt settling even have automatic cleaning mechanism.Its result, protective tube is changed every several years needs, has produced the maintenance cost that is used for this.In addition, automatic cleaning mechanism complex structure and member number are many, produce initial cost and its maintenance cost.With respect to the luminous needed electricity charge of UV-lamp and pipe replacement cost, these maintenance costs and initial cost are occupied very important ratio, and the reduction of these expenses becomes problem.
In order to solve this problem, the countermeasure technology in (patent documentation 1) record is for example proposed.The prior art of (patent documentation 1) record has following structure: at arranged outside solid cylinder along the UV-lamp of vertical configuration major axis, make processed water along this barrel surface film like flow down, do not possess protective tube in the described prior art.Since from UV-lamp to arriving the part that does not exist inorganics or organism to adhere to before the processed water, so have the advantage that the light quantity of not producing reduces.
In addition, in (patent documentation 2), be described below content: in water treatment device, ultraviolet ray reflection space is supplied with on the vaporific attitude of processed water ground, and wherein this water treatment device possesses: be configured in UV-lamp and processed feed mechanism, processed water conveying end, gas supply port and conveying end in the reaction vessel.
But, in the prior art of (patent documentation 1) record, because processed water to flow down with the wall state of contact, therefore becomes the film of the thin thickness of liquid film.In addition, in the prior art of (patent documentation 2) record, because supply with vaporific attitude, the problem that physical presence is swum and adhered to protective tube, ultraviolet utilising efficiency is also low.Generally to sterilization or not activate effective ultraviolet wavelength be near the 254nm, the decay of the ultraviolet ray of this wavelength in water is little.Therefore, if the film of processed water is thin or vaporific attitude, then Duo Shuo light is not effectively used and film arrival wall by processed water.This situation is carrying out becoming remarkable under the occasion to the low turbidity such as secondary treatment water that like water purification or following water, low colourity of UV treatment.
In addition, absorb ultraviolet situation fully, might exist for the ultra-violet sterilization that produces, the extremely low situation of activatory utilising efficiency not at wall.Wall is a minute surface, and this utilising efficiency of the situation of uv reflectance improves fully, because processed water often contacts this minute surface, can not avoid adhering to gradually inorganics or organism and then reflection of light rate equally with the situation of protective tube and reduce.
Thus, in the prior art of (patent documentation 1), (patent documentation 2) record, generation can not effectively utilize with sterilization or not activate is near the ultraviolet problem of the wavelength 254nm of purpose.

Embodiment
Various embodiments of the present invention will be described to utilize accompanying drawing.
(first embodiment)
Fig. 1 is the stereographic map of expression as the structure of the UV water treatment equipment of first embodiment of the present invention.
In the UV water treatment equipment of present embodiment, on the top of columnar wall 12 flat board 13 is installed, on dull and stereotyped 13, two supplying openings 14 are set, on supplying opening 14, be provided for flowing through the pipe arrangement 15 of processed water.The water collecting part 26 of cone shape is set in the bottom of wall 12, water shoot 20 is set on water collecting part 26.
In the inboard of wall 12, the supporting member 22 of UV-lamp is installed in the many places of the circumferential direction at above-below direction two places.The supporting member 22 of UV-lamp is made of globular fixed part and bar-shaped support, and the globular support also is set on UV-lamp 10, and by the UV-lamp supporting member, UV-lamp 10 is with the state configuration parallel with wall 12.
Owing to be so constructed,, fall to the vertical below by gravity so the processed water 18 that flows into flows into from the supplying opening 14 on the top of the vertical that is positioned at UV-lamp 10.As mentioned above, supplying opening 14 is provided with at distance UV-lamp 10 and wall 12 places of keeping at a certain distance away, and the processed water 18 of whereabouts does not contact with either party in UV-lamp 10, the wall 12.In addition, the processed water 18 of whereabouts does not contact with the fixing UV-lamp supporting member 22 of UV-lamp 10 yet.Be used for being provided with by above-mentioned mode, do not contact with the processed water 18 that falls equally with UV-lamp supporting member 22 to the feed cable 24 of UV-lamp 10 supply capabilities.
UV-lamp 10 is radiated ultraviolet ray by means of power, and the processed water 18 that falls is carried out sterilization, do not activate.Arrive the processed water 18 of UV-lamp 10 belows, and collected by water collecting part 26, flow out from water shoot 20.
If contact solid surface, then liquid expansion herein, but structure as present embodiment, processed water 18 flow into from supplying opening 14 arrive water collecting part 26 before with the discontiguous situation of solid surface under, because the molecule of liquid is each other by the surface tension drawing, therefore compare with situation about contacting with solid halfway, big variation does not take place in the shape of fluid column.
As this result,, can access the elongated thick thick water column of the liquid middle distance that ultraviolet ray passes through (in the liquid apart from From) by processed water supplying opening 14 is fully become big.Because near in sterilization or the wavelength 254nm that effect is big aspect not activating the decay of ultraviolet ray in water is little, the liquid middle distance that ultraviolet ray is passed through by this structure is elongated and then can increase the ratio of effective utilization thus.
In addition, owing to processed water 18 does not contact with UV-lamp 10, so the surperficial non-cohesive inorganics or the organism of UV-lamp 10, do not produce the problem of the light quantity reduction that enters processed water 18 that causes by those dirt settlings yet.In addition, because the pipe and also do not need automatic cleaning mechanism of not needing protection, can reduce the initial cost of device thus and by changing the maintenance cost that protective tube produces.
But, under the situation of outside line lamp 10 contingency damages,, for example also the protective tube that has sealed the bottom can be set around UV-lamp 10 in order to avoid mercury that comprises in inside and sheet glass flow out together with treating water.This situation needs that also processed water supplying opening 14 is arranged to processed water 18 and did not contact with this protective tube before arriving water collecting part 26.
During long-time use UV water treatment equipment, the processed water 18 that arrives water collecting part 26 produces small water droplet, and this water droplet rises and then may be attached on the UV-lamp 10.In this case, this water droplet is in the surface evaporation of UV-lamp 10, and ion or turbid matter (Turbid Quality after the dissolving) on the surface of composition attached to UV-lamp 10, may reduce the light quantity that offers processed water 18.In order to prevent this situation, for example consider to supply with pure water or ultrapure water continuously from another top for the surface with UV-lamp 10 contacts and form film.In addition, can consider to be equipped with the easy and cheap thin resin cartridge of replacing in the outside of UV-lamp 10.
Thus, by adopting the structure of present embodiment, do not need the protective tube and the automatic cleaning mechanism of silica glass system necessary in the existing apparatus.Its result can access the advantage that initial cost reduces, maintenance cost reduces.In addition, because the water column chap processed water 18 can be fallen the time therefore than contacting and form the situation that film like flows down with wall 12, can improve ultraviolet effective rate of utilization.
Fig. 2 is the cross-sectional view at supplying opening 14 places of present embodiment.The processed water 18 that flows into falls (gravity falls the The Ru) from supplying opening 14 gravity of processed water.Have under a plurality of situations at supplying opening 14, wish that in distance UV-lamp 10 equidistant modes this being set is provided with the position.
As mentioned above, Fig. 2 (a) is the example that supplying opening 14 has the situation at two places, and Fig. 2 (b) is the example that supplying opening 14 is increased and is the situation of 8 places setting at circumferential direction.
Thus,, compare with the not equidistant situation of distance UV-lamp 10 by a plurality of supplying openings 14 are provided with in distance UV-lamp 10 equidistant modes, can make sterilization, not discrete (the ば ら つ I) of activation performance diminish.
The situation that the light quantity of UV-lamp 10 is very big, sterilization, the discrete influence of activation performance does not diminish, and improves in hope under the situation of ultraviolet effective rate of utilization, and the supplying opening 14 of concentric circles ground multi-layer configuration processed water is also effective.
Fig. 3 is the sectional drawing as the supplying opening place of the variation of the supplying opening 14 of present embodiment, and Fig. 4 is the stereographic map of the shape of the processed water that falls of expression gravity.
As shown in Figure 3, the supplying opening 14 of processed water is the ring-like shape with certain width, and as shown in Figure 4, the processed water 18 that falls of gravity is formed on the inboard and has the cylindric of gas cloud from here.
For reduce sterilization, activation performance is discrete, the shape of wishing the supplying opening 14 of processed water is just round, in addition, from effectively utilizing on the ultraviolet viewpoint, also more than 14 concentric circles ground of supplying opening of ring-like shape can be equipped with.
In addition, also can and use the ring-like supplying opening shown in a plurality of supplying openings 14 shown in Fig. 2 and Fig. 3 14.
Generally, light reflects during incident to water from air, in order more effectively to carry out sterilization, the non-activation treatment of processed water 18, wishes to reduce as far as possible the reflection at the water surface.Therefore the input angle of light is 0 degree, that is, light is ideal with respect to water surface vertical incidence.
Therefore in the water column of ring-like shape as shown in Figure 4,, compare reflection still less with the water column of the processed water 18 of shape shown in Fig. 2, can further improve ultraviolet utilising efficiency because the ultraviolet ray of radiation laterally from central division is with respect to water surface vertical incidence.
But, processed water is formed ring-like situation, because processed water contact with the UV-lamp supporting member 22 of shape shown in Figure 1,, or it is hung down from flat board 13 so UV-lamp 10 need be fixed on the flat board 13 as the lid on device top.
