Fig. 1, Fig. 2, Fig. 3 show the embodiment of sterilizing unit of the present invention, and these figure show the inside of sterilizing unit, and Fig. 1 is front view, and Fig. 2 is side-view, and Fig. 3 is vertical view.In addition, a part for the influx of sterilizing unit of the present invention and ultraviolet lamp is amplified the stereographic map shown by Fig. 4, (A) for showing the figure of the position relationship of influx and ultraviolet lamp, (B) is the figure of the relation that hole and the tube end arranged on influx is described.
In these figures, 101 is the influx (flowing into influx in sterilization tank to make to answer the liquid of the water of sterilization or hot water etc.) of the sterilization tank 100 of sterilizing unit, and 104 is spout, and 111,112,113,114,115,116 is ultraviolet lamp.Liquid flows in sterilization tank 100 from influx 101, accepts the irradiation of ultraviolet lamp 111 ~ 116 and sterilization, flows out from the spout 104 that the position that almost diagonal lines is relative of the influx 101 sterilization tank 100 is arranged.
In this embodiment, 3 ultraviolet lamps 111,112,113 certain interval that is separated by forms a line and configures, and other 3 ultraviolet lamps 114,115,116 certain interval that is separated by forms a line and configures, and altogether configures 2 row, 6 ultraviolet lamps.In addition, ultraviolet lamp is U-shaped cast, towards the liquid flow direction (direction of the arrow A of Fig. 3) along sterilizing unit side and U-shaped is set.
On the sidewall 109 of sterilization tank 100, along the inclined-plane 109A that the direction of liquid-flow is inner outstanding to sterilization tank gradually, arrange (with reference to figure 3) in liquid flow direction in the mode consistent with the setting position of ultraviolet lamp.In addition, on the bottom 106 of sterilization tank 100, the direction along liquid-flow is set and inclined-plane 105 upward, this inclined-plane 105 with the boundary 107 of bottom 106 on form several hole 105A(with reference to figure 5).
Below, with reference to figure 4, describe the structure of the influx 101 according to the sterilizing unit of the present embodiment in detail.
The shape that influx 101 bends for L-shaped, it is made up of with the tube 101b extended towards stenlizing layer 100 bottom the inlet portion 101a connecting external water source.The bottom surface 101c of tube 101b is closed, and liquid can not be passed through.In addition, the side of tube 101b is arranged the hole 102 of the circle of many diameter r.The I display surface of Fig. 4 (A) not providing holes 102 on the region of nearest ultraviolet lamp 114.Further, the diameter r in hole 102 is little compared with the diameter R of tube 101b, is that the mode of more than 2 times of the sectional area of tube 101b is arranged according to the summation of its port area.In the present embodiment, the diameter R of setting tube is 100mm, and the diameter r in hole 102 is 20mm, but the diameter r in hole 102 is preferably 15mm to 20mm.
In the influx 101 so formed, because the bottom surface 101c of tube 101b is closed, the formation of the vortex shape liquid sinuous flow that can prevent inclusion of air from causing, and bottom the sterilization tank that causes of the liquid flowed down or the damage of internal machine.
In the sterilizing unit of the present embodiment, make to answer the liquid of sterilization to flow into via influx 101, liquid is sent in sterilization tank 100 via the multiple holes 102 formed on the tube 101b of influx 101.Herein, liquid in sterilization tank 100 is sent to enter from the dispersed state torrent in multiple hole 102 via influx 101.In addition, owing to being closed by the bottom surface 101c of tube 101b, not providing holes 102 on the region I towards nearest ultraviolet lamp 114, therefore, on the bottom of sterilization tank 100 or ultraviolet lamp 114, does not have direct, fierce water impact.Therefore, do not worry damaging bottom or ultraviolet lamp 114.
The liquid flowed in this groove accepts the ultraviolet irradiation sent by the ultraviolet lamp 111,112,113,114,115,116 configured in groove, and kills the bacterium in liquid.Then, by the hole arranged on the side of the tube 104b towards above-below direction of spout 104, flow out via export department 104a.In order to prevent entrained air, the bottom surface 104c of spout 104 is also closed in the same manner as influx 101.Further, the hole tube 104b of spout 104 arranged also has the structure same with influx 101.
, utilizing the irradiation of ultraviolet lamp to the liquid sterilization flowed through in sterilization tank 100 herein, in order to improve this germ-killing efficiency, invention has been all improvement.First, consider the illumination efficiency of ultraviolet lamp, adopt the ultraviolet lamp of U-shaped cast in the present invention, U-shaped configures according to the side towards the liquid flow direction A along sterilization tank 100.By configuration like this, the uviolizing frequency to the liquid flowed through in sterilization tank 100 increases, and can improve germ-killing efficiency.
In addition, along the liquid stream of the sidewall 108,109 of sterilization tank 100, or along the liquid stream of bottom 106, be difficult to the irradiation accepting ultraviolet lamp, therefore probably can not kill the bacterium in liquid.But, according to the present invention, the setting position of the ultraviolet lamp of sidewall 108,109 is provided with to inner outstanding inclined-plane 108A, the 109A of sterilization tank 100, bottom 106 is provided with the inclined-plane 105 upward, direction along liquid-flow.Thus, be difficult to the liquid stream of the part accepting ultra violet lamp, towards the direction of ultraviolet lamp, can positively sterilization.Below, inclined-plane 108A, 109A and 105 is described in detail.In addition, because inclined-plane 108A and inclined-plane 109A is same structure, the inclined-plane 109A that sidewall 109 is arranged only is described below.
In the inclined-plane 109A that sidewall 109 is arranged, if excessive with the angle [alpha] of 109 one-tenth, side, then the change of liquid flow direction diminishes, and forms sinuous flow and becomes difficult, make liquid little towards the effect of ultraviolet lamp.In addition, if too small, then the liquid flow direction clashing into inclined-plane becomes Return-ing direction.Therefore, the angle [alpha] of inclined-plane 109A is 105 degree to 110 degree, forms (with reference to figure 4 (A)) according to the mode of center on the extended line on inclined-plane of ultraviolet lamp.Thus, change nyctitropic liquid stream by inclined-plane 109A and flow towards ultraviolet lamp, positively can utilize ultraviolet lamp sterilization.
As shown in Figure 1, the inclined-plane 105 that bottom 106 is arranged be arranged on flow direction configuration ultraviolet lamp 111 and 112,112 and 113,114 and 115, on the mid-way of 115 and 116 respective flow directions, respectively along flow direction upward.Similarly, influx 101 and the mid-way of the flow direction of ultraviolet lamp 111,114 also arrange inclined-plane.Thus, changed by inclined-plane 105 nyctitropic, along the passive rising of bottom 106 flowing fluid of sterilization tank 100, towards ultraviolet lamp flowing, positively can utilize ultraviolet lamp sterilization.
In addition, on the inclined-plane 105 of this embodiment, as shown in Figure 5, several hole 105A is formed.Therefore, along the part of the liquid of flows by this hole through inclined-plane 105, prevent retention liquid near the boundary 107 on bottom 106 and inclined-plane 105 and cause the bacterial concentration in the liquid near boundary 107 to uprise.Through the liquid in this hole, by means of the upstream formed by inclined-plane 105, be sterilized eventually through the irradiation of ultraviolet lamp.Structure the following detailed description of this inclined-plane 105 and several hole 105A and the liquid stream by them.
As shown in Fig. 5 (B), this hole 105A is the long half elliptic of above-below direction or close to half elliptic shape, and the length of transverse direction is little.Therefore, be flow along the edge of aperture to various direction as shown in Figure 6 by the liquid stream of aperture 105A.Further, due to the liquid stream 110 of larger amount flowed along bottom 106, the pressure of the vicinity on inclined-plane 105 is large, and the liquid tilting to rise along this inclined-plane 105 rises with speed more slowly.On the other hand, blocked by inclined-plane 105 by the most of liquid flowing through bottom of the liquid stream 120 of aperture 105A, the pressure of its opposition side becomes smaller.Therefore, due to the sharply change to low pressure (with high-pressure section ratio), because its pressure difference makes the speed of liquid sharply increase.At this moment, overall as the liquid stream 120 in Fig. 6, towards oblique upper after passing hole.If show state during this liquid communication via hole 105A, as shown in Figure 7, become the liquid stream being scattered in oblique upper, it almost all accepts the ultraviolet irradiation from ultraviolet lamp.By the liquid stream 120 in such hole, by after be scattered in all directions as shown in Figure 7 with large speed, such as rise with the state of dispersion, after collaborating with the liquid stream of entirety, near ultraviolet lamp, through the uviolizing that ultraviolet lamp sends, accept sufficient germicidal action, kill the bacterium class material contained completely.
Like this, in the device of embodiment 1, rise obliquely upward due to inclined-plane 105 along bottom 106 flowing fluid stream 110, flow through near ultraviolet lamp.On the other hand, the liquid stream 120 nearest from bottom 106 is passed by the hole 105A formed on inclined-plane, forms the liquid stream of the high speed of dispersion simultaneously as previously mentioned, flow near ultraviolet lamp and accept ultraviolet irradiation.In addition, the water of the part 105B between each hole 105A flowing through inclined-plane 105, is introduced by with the water of high speed passing hole 105A, can not retention in junction section same passing hole 105A.
Therefore, along bottom 106 flow water rise on inclined-plane while, nearest the flowing through the water passing hole 105A on bottom 106 and disperse from bottom 106, all water is by near ultraviolet lamp, there is not water that is that be not subject to uviolizing completely or that be not almost subject to uviolizing, substantially can kill detoxification bacterium class material completely.
In addition, in the present embodiment, form across the side wall surface 108 of side and the side wall surface 109 of opposite side the inclined-plane 105 that porose 105A is set, therefore, the liquid flow through along bottom 106 almost all rises along inclined-plane 105, or forms the high-speed liquid stream of passing hole 105A dispersion.Thus, due to influx 101 and ultraviolet lamp 111(114) between the liquid that disperses of the inclined-plane 105 that arranges and the liquid risen and passing hole 105A, become by sending ultraviolet lamp 111(114) ultraviolet near, positively accept ultraviolet irradiation.Similarly, due to ultraviolet lamp 111(114) and ultraviolet lamp 112(115) between the inclined-plane that arranges and the liquid risen, at two ultraviolet lamp 111(114) and 112(115) between, towards the ultraviolet irradiation position of two lamps, therefore accept by two ultraviolet lamp 111(114), 112(115) ultraviolet irradiation.In addition, the water of passing hole 105A also accepts the ultraviolet irradiation by these ultraviolet lamps.Further, liquid is also due to ultraviolet lamp 112(115) and ultraviolet lamp 113(116) between the inclined-plane that arranges and rising.Or passing hole dispersion, accept by ultraviolet lamp 112(115), 113(116) etc. ultraviolet irradiation, kill the bacterium class material in liquid.
In addition, in the present embodiment, the two ends on inclined-plane engage in the mode of side wall surface 108,109 with close adhesion respectively, do not exist by the liquid between inclined-plane 105 and side wall surface 108 or 109 and make, all arranged by the mode in ultraviolet lamp 111,112,113,114,115,116 near any one with all liquid, positively carry out sterilization.
In addition, in the present embodiment, as mentioned above, owing to arranging spout 104 in the position with influx 101 almost cornerwise opposite, the liquid stream therefore in groove does not deposit and flows, and improves the germ-killing efficiency utilizing ultraviolet lamp.
Fig. 4 (C) is the figure of display according to other embodiment of influx 101 of the present invention.In the present embodiment, the inlet portion 101d connecting the external water source of influx 101 forms the cone-shaped expanded towards tube 101b.By forming such structure, the caliber of tube 101b can be expanded while maintenance is connected to the caliber of the part of the external water source of inlet portion 101d.
In the embodiment shown in Fig. 1 to Fig. 3 of the present invention, with the direction 2 piece almost vertical relative to liquid flow direction, arrange configuration ultraviolet lamp along liquid stream 3, by altogether 6 ultraviolet lamp formed disinfection structure, but water quality inferiority or when must process the short period of time such as large water gaging etc., when must improve germ-killing efficiency further, with the direction 3 piece almost vertical relative to liquid flow direction, arrange configuration ultraviolet lamp along liquid stream 3, form the sterilization utilizing 9 ultraviolet lamps altogether.In this case, because the distance of influx 101 with ultraviolet lamp reduces, and send into relatively large liquid to sterilization tank inside, the speed of the liquid therefore sprayed from the hole 102 that the tube 101b of influx 101 is arranged increases.Therefore, even in the not providing holes of the region towards ultraviolet lamp, also worry to damage ultraviolet lamp due to the liquid stream of this high speed.
In this case, as the present embodiment, if the caliber of tube 101b can be increased, then more substantial liquid can be supplied, therefore, it is possible to the short period of time processes large quantity of fluid.Further, owing to also the diameter in the hole 102 that this tube 101b is arranged can be increased, therefore, it is possible to make the flow velocity of the liquid sprayed from hole 102 decline.Thus, the liquid damage ultraviolet lamp owing to spraying from hole 102 can be worried.
In addition, because the relation of installation space must by the situation of the reduced profile of device, even if the radical of ultraviolet lamp is 6 as described in above-described embodiment piece, the distance between influx and ultraviolet lamp is also little, adds the danger because liquid stream generation ultraviolet lamp at a high speed damages.In this case too, if having the influx of the inlet portion 101d according to cone-shaped of the present invention, then can reduce the flow velocity of ejection liquid owing to forming the large hole 102 of diameter, therefore, it is possible to eliminate above-mentioned danger.
The figure of example when Fig. 9 is the ultraviolet lamp of the intensive configuration of display sterilizing unit of the present invention.Although sterilizing unit of the present invention has high germ-killing efficiency, but in the situation of seeking better germ-killing efficiency in narrow and small installation space, as shown in Figure 9, on the basis of the ultraviolet lamp of 6 shown in Fig. 3 111 ~ 116, with and these ultraviolet lamps 111 ~ 116 mode of forming interval substantially uniformly ultraviolet lamp 121 ~ 126 is set.In this case, consider the germ-killing efficiency of lamp, the U-shaped of additional ultraviolet lamp 121 ~ 126 is set according to the mode that the direction of the U-shaped with ultraviolet lamp 111 ~ 116 is orthogonal.After so configuring ultraviolet lamp to high-density, the microorganism of strong oxygen resistence can be killed.In addition, owing to configuring ultraviolet lamp to high-density, can improve the sterilizing ability in the unit time, sterilizing unit can process the fluid of more various flow.
Figure 10 is the figure of other example of the configuration of the ultraviolet lamp of display transformation sterilizing unit of the present invention.In this example embodiment, ultraviolet lamp is, 3 ultraviolet lamps 131,132,133 are arranged in a row configuration at certain intervals, other 3 ultraviolet lamps 134,135,136 are arranged in a row configuration at certain intervals, there are other 3 ultraviolet lamps 137,138,139 be arranged in row at certain intervals and configure again, are altogether configured with 3 row, 9 ultraviolet lamps.When so increasing row, compared to influx 101 and spout 104 are configured on the diagonal, position slightly middle on the direction vertical with flow direction arranges influx 101 and spout, also can supply sufficient liquid stream for the ultraviolet lamp 131,137 and 133,139 arranged at two ends, be therefore preferred.
Figure 11 is the figure of another example of the configuration of the ultraviolet lamp of display transformation sterilizing unit of the present invention.In this example embodiment, ultraviolet lamp is, 3 ultraviolet lamps 141,142,143 are arranged in row at certain intervals and configure, other 3 ultraviolet lamps 144,145,146 form a line at certain intervals and configure, other 3 ultraviolet lamps 147,148,149 are had to be arranged in row at certain intervals and to configure again, there are other 3 ultraviolet lamps 150,151,152 be arranged in row at certain intervals and configure again, are altogether configured with 4 row, 12 ultraviolet lamps.When increasing row so further, influx and spout make branch's tubular structure as shown in the figure, form the 1st influx 101 ' and the 2nd influx 101 ' ', the 1st spout 104 ' and the 2nd spout 104 ' '.By structure like this, make the ultraviolet lamp 141,150 and 143,152 for arranging at two ends also can supply sufficient liquid stream.
Figure 12 for display by having 4 row, 12 ultraviolet lamps shown in Figure 11 and branching type influx, the sterilizing unit 2 of spout structure couples together, and has the figure of the sterilizing unit of the structure so formed.The sterilizing unit of this embodiment is effective when processing the liquid of very large flow.In the apparatus, the dividing plate 160 producing sinuous flow at connection section is made ripple tabular, make the sinuous flow that also can produce liquid in this part.
In the sterilizing unit of Figure 10, Figure 11, Figure 12, in the same manner as Fig. 9, additional ultraviolet lamp can be set between each ultraviolet lamp.After so configuring ultraviolet lamp to high-density, in the same manner as Fig. 9, make it possible to improve the sterilizing ability in the unit time, sterilizing unit can process the fluid of more various flow.
The ultraviolet lamp used in sterilizing unit of the present invention due to high price and poor impact resistance, therefore with protective tube protection, but in order to not reduce the radiation response of this ultraviolet lamp, being protected according to the quartz protecting tube formed with transparency silica glass and forming.Ultraviolet lamp keeps/is fixed on structure in sterilizing unit as shown in Figure 8 together with quartz protecting tube.
Ultraviolet lamp 200 surrounds with non-contacting state with quartz protecting tube 230 for showing by Fig. 8; the figure of the state of the top board 220 of sterilizing unit is fixed on together with quartz protecting tube 230; (A) be sectional side view; (B) be vertical view; (C) for removing is according to the vertical view of the state of quartz protecting tube block piece 250 of the present invention; (D) be that U-shaped in order to show ultraviolet lamp 200 shows its part, from the view of the direction of arrow that the arrow D of Fig. 8 (A) looks.
Quartz protecting tube 230 keeps with quartz protecting tube metal fixing 210 via quartz protecting tube rubber mounting block 240; but usually can enter air in the space between quartz protecting tube 230 and ultraviolet lamp 200; if the liquid such as water or hot water enters in sterilization tank; silica tube 230 will rise due to buoyancy, then can clash into ultraviolet lamp installation portion 260.Due to this collision, the accident that quartz protecting tube 230 damages can be there is.In addition, there is the situation of high temperature as thermal water by the temperature of the liquid of sterilizing unit process, also have the situation of low temperature as when cold district processing drinking water.Further; because stainless steel (SUS304) normally used in quartz protecting tube metal fixing 210 is different from the coefficient of expansion of the silica glass forming quartz protecting tube 230; if be completely fixed buoyancy direction (length direction), then can there is the accident because the dilation generation quartz protecting tube of silica glass damages.
In order to prevent the damage accident of such quartz protecting tube 230, the quartz protecting tube block piece 250 stoping quartz protecting tube 230 to the movement in the buoyancy direction of ultraviolet lamp installation portion 260 is set.This block piece 250 can be installed in quartz protecting tube metal fixing 210 movably to buoyancy direction, between the upper end of quartz protecting tube 230, form narrow and small gap.Particularly, is the elongated hole of the above-below direction of Fig. 8 (A) at block piece 250 with the open holes that arranges on the installation site of quartz protecting tube metal fixing 210, is loosely fixed on quartz protecting tube metal fixing 210.Therefore; on the above-below direction of Fig. 8 (A); when applying the power making quartz protecting tube 230 move up due to buoyancy or bulging force etc., quartz protecting tube 230 contacts block piece 250, resists the lax bed knife of block piece 250 and rises together with block piece 250.Between this rising stage, the power to the top of quartz protecting tube 230 is weakened due to block piece 250, has cushioned the impact caused of rising, can prevent the damage due to collision.
