Detailed description of the invention

Below, for one embodiment of the invention, explain on one side with reference to accompanying drawing on one side.

Embodiment 1

Fig. 1 is the summary of the structure of the carbonate spring generating apparatus 10 of explanation in one embodiment of the inventionFigure. As shown in Figure 1, the carbonate spring generating apparatus 10 of the present embodiment has: for by carbon dioxide gasThe gas bubble stream 12 that is dissolved in the water of bubble and for by the dioxy of carbon dioxide bubble injected waterChange carbon generating unit 20 and bubble injection unit 30.

Particularly, the water for example injecting from the water injection pipe portion 40 being connected with water channel, by following workFor the selection portion 48 of triple valve, optionally circulate in the 1st supply unit 42 and the 2nd supply unit 44Either party or be truncated. In the situation of water flowing in the 1st supply unit 42, raw with following carbon dioxideTablet (tablet) 24 reactions as raw material in one-tenth portion 20 produce carbon dioxide. ProduceCarbon dioxide is having sneaked into bubble form as former state under the state in water, by the life as triple valveBecome switching part 46 to circulate in gas bubble stream 12.

Switch generating unit 46 and be set up, with by the 2nd supply unit 44 be arranged on gas bubble stream 12The 2nd portion that spues that the 1st of terminal spues portion 18 or do not spue by gas bubble stream 1250 either party is optionally communicated with or blocks. Make water circulate in the 2nd supply by selection portion 48Portion 44, and by generating switching part 46, water is spued in the mobile situation of portion 18 to the 1st, bubbleIn following bubble injection unit 30 injected waters. In addition, by selection portion 48, water is circulated inThe 2nd supply unit 44, and make water to the 2nd mobile situation of portion 50 that spues by generating switching part 46Under, can not generate carbonate spring, the water being injected into from water injection pipe portion 40 is as former state from the 2nd portion that spues50 are discharged from. Moreover, for preventing owing to entering in the mobile water generation adverse current of the 2nd supply unit 44Carbon dioxide generating unit 20, the pipe arrangement of the water being discharged from from carbon dioxide supply unit 20, withNear that the 2nd supply unit 44 collaborates is provided with check (non-return) valve 54.

Wherein, gas bubble stream 12 is for noting by following carbon dioxide generating unit 20 or bubbleEnter portion 30 and the current of injecting carbon dioxide bubble are logical, this carbon dioxide bubble is dissolved in the water thusStream. , carbon dioxide bubble is by PlugFlow(plug flow) mode (cast reactive mode)Dissolve. In gas bubble stream 12, the effective diameter of gas bubble stream 12 is determined, to makeThe viscosity of the carbon dioxide bubble in this water under the flow velocity of the mobile water of this gas bubble stream 12Resistance, becomes the situation that the carbon dioxide bubble in this gas bubble stream 12 is maximum diameter, is thisMore than the buoyancy of this carbon dioxide bubble in the situation of the effective diameter of gas bubble stream 12. Like this,Can prevent flowing not at the interior carbon dioxide bubble delay of gas bubble stream 12 and carbon dioxide bubbleStable. This result, carbon dioxide can be dissolved in water well, obtains needing the carbonate spring of concentration.Moreover, below show as in the situation of water, except as otherwise noted, comprise and be injected with carbon dioxide bubbleWater.

Particularly, according to Archimedes principle, buoyancy F draws according to following formula (1).

[several 1]

$F=\frac{\mathrm{\π}{D_B}^3\mathrm{\ρg}}{6}---\left(1\right)$

At this, D_BFor the maximum [m] of bubble diameter, the density [kg/m that ρ is water³], g is that gravity addsSpeed [ms^-2]。

On the other hand, if consider at the flow of the mobile water of gas bubble stream 12 etc., circulate inThe water of gas bubble stream 12 is turbulent flow, and its viscous drag R is approximate as what obtain according to experiment valueFormula draws like that as shown in the formula (2).

[several 2]

$R=\frac{\mathrm{\π}}{8}{D_B}^2\mathrm{\ρ}{C}_D{v}^2---\left(2\right)$

At this C_DThe resistance coefficient bearing for bubble, for

[several 3]

$C_D={(0.55+\frac{4.8}{\sqrt{\mathrm{Re}}})}^2$

Re is dimensionless number Reynolds number, Re=Dv ρ/μ,

D is the effective diameter [m] of gas bubble stream 12, the flow velocity [m/s] that v is water, and what μ was water is stickyDegree [Pas].

At this, the diameter of carbon dioxide bubble is maximum, is the effective diameter of gas bubble stream 12Buoyancy F and viscous drag R balance in situation, for

[several 4]

$\frac{\mathrm{\π}}{5}{D_B}^2\mathrm{\ρ}{C}_D{v}^2=\frac{\mathrm{\π}{D_B}^3\mathrm{\ρg}}{6}---\left(3\right)$

By its arrangement, for

[several 5]

$\frac{3}{4}{(0.55+\frac{4.8}{\sqrt{\frac{\mathrm{Dv\ρ}}{\mathrm{\μ}}}})}^2{v}^2=D_{B}g---\left(4\right)$

Flow velocity v is the value of flow H divided by cross section (the passing through area) gained of gas bubble stream 12,For

[several 6]

$v=\frac{4H}{\mathrm{\π}{D}^2}$

Therefore using above-mentioned (4) formula as flow H and bubble diameter D_BRelation decomposing solve and can obtainGo out relation as shown in Figure 2. From the relation obtaining in this wise, based on carbonate spring generating apparatus 10The flow H[m of needed water³/ s], the effective diameter D[m of gas bubble stream 12] based on carbon dioxideThe diameter D of bubble_BMaximum set. Particularly, to become the district more than curve in Fig. 2The mode in territory is set the effective diameter of gas bubble stream 12. In the example of Fig. 2, known water exampleIf the mode with flow H=10L/ minute is in the situation that gas bubble stream 12 circulates, gas bubbleThe effective diameter D of stream 12 is about below 16.5mm.

Moreover, in the present embodiment, the effective diameter of pipe, the cross section that refers to pipe is right in circular situationShould be in this diameter of a circle, in the case of the shape beyond this, the circle equal corresponding to sectional area is straightThe concept in footpath.

On the other hand, in the present embodiment, the carbon dioxide bubble in injected water is by PlugFlow sideFormula is dissolved, and therefore the length of gas bubble stream 12 is determined, to make to be injected with carbon dioxide bubbleWater time (passing through the time) of circulating at gas bubble stream 12, become (the institute in order to obtain regulationExpect) more than required time of the concentration of ordinary dissolution of carbon dioxide. At this, above-mentioned by time T [s]As the length L [m] of gas bubble stream 12 and the relation of the flow velocity v of mobile water therein, for

[several 7]

$T=\frac{L}{v}=\frac{\mathrm{\πL}{D}^2}{4H}---\left(4\right)$

It is solved for L, for

[several 8]

$L=\frac{4\mathrm{HT}}{\mathrm{\π}{D}^2}---\left(5\right)$

Therefore, exist gas bubble stream 12 thinner, the effective diameter D of gas bubble stream 12 is lessThe length L of gas bubble stream 12 relation of more growing of just having to. Particularly, send out according to the applicationBright persons' experiment, at flow H=8L/ minute, the effective diameter D of gas bubble stream 12 is 12mmSituation under, for example, for obtaining the carbonate spring as the 1000ppm of the gas concentration lwevel of expectingBe about 4 seconds by time T, therefore the length L of gas bubble stream 12 need to be in about 5m withOn. Moreover water is used as the concept that comprises water and hot water in this description. In addition, carbonate springUsed as the concept that extensively comprises the water that is dissolved with carbon dioxide, be not limited to for example wantThe carbonate spring of asking the spa code of gas concentration lwevel more than 250ppm to specify. Moreover, molten at bubbleThe flowing of water of separating in stream 12 can be seen as in the situation of complete turbulent flow, the resistance coefficient C of bubble_DAlso can replace above-mentioned (3) formula of use and be approximately C_D=0.44。

In gas bubble stream 12, be provided with at least one restriction 14, the effective diameter ratio of restriction 14The effective diameter of gas bubble stream 12 that restriction 14 is not set is little. Fig. 3 contains a restrictionThe length direction of 14 gas bubble stream 12, i.e. axial sectional view.

When water passes through restriction 14 as shown in Figure 3, the carbon dioxide bubble injecting in this water is by thinGranulation. Therefore,, because the contact area of carbon dioxide bubble and water increases, can expect dissolution time contractingShort. According to inventor's experiment, learn and there is no the effective diameter d of part of restriction 14₁₂For 12mmGas bubble stream 12 in, configured 5 effective diameter d₁₄After restriction 14 for 8mm, forGas bubble stream 12 below 1.5m, just can realize and not have to need in the situation of restriction 14The concentration of ordinary dissolution of the carbon dioxide that the gas bubble stream 12 of 5m is identical. , by gas bubbleRestriction 14 is set in stream 12, can shortens the length of gas bubble stream 12. This gas bubbleThe length of stream 12 is designed, to make, in situation that carbon dioxide and current are logical, can only spending twoCarbonoxide solubilized until the time of the desired gas concentration lwevel of carbonate spring generating at gas bubbleStream 12 passes through.

At this, by the effective diameter d of gas bubble stream 12₁₂Be made as 12mm, will flow at gas bubbleThe flow H of the water circulating in road 12 is made as 8L/ minute, repeatedly changes the effective diameter d of restriction 14₁₄Size, calculating gas bubble stream 12 does not have the part of restriction and the pressure differential of restriction 14,Obtain relation as shown in Figure 4. Like this, according to the big or small pressure differential of the effective diameter of restriction 14 notWith minimum. Therefore, can think that the carbon dioxide bubble in water carries out grain refined, be not by restriction 14With the pressure differential of part that there is no restriction, but caused by speed difference.

In the downstream than above-mentioned restriction 14 of gas bubble stream 12, be provided with pressure and keepPortion 16. This pressure retaining parts 16 is openings of for example path or slit-shaped, is in order to prevent due to gasBubble dissolves the terminal part opening significantly of stream 12, thereby atmosphere is from the terminal of gas bubble stream 12Portion enters to inside, and the pressure drop in pipe to atmospheric pressure arranges. Thus, gas bubble streamThe pressure of the water in 12 is maintained.

In addition, expect to do one's utmost to shorten restriction 14(is this in the situation that multiple restriction 14 is setAmong restriction 14, be arranged on the downstream of gas bubble stream 12, i.e. pressure retaining parts 16The restriction 14 of side. Hereinafter referred to as final restriction 14. ) and spue as the 1st of the carbonate spring that spuesThe distance of the shower head 18 of mouth. Particularly, even be preferably made as by final restriction 14 by thinThe carbon dioxide bubble residue of granulation and dissolving in residual situation, from this final restriction 14 to pouringBathe and in a stream of 18, dissolve residual bubble and also can partly not be detained, but keep by the shape of grain refinedThe distance that state spues from shower head 18. Like this, can prevent from this final restriction 14 to shower headIn 18 stream, dissolve residual bubble and be detained and form air pocket, this air pocket by plug-flow once andBy shower head 18, send bubble bubble sound, or mobile such making that get clogged of waterThe situation that user does not feel soon. It is special this hole at the carbonate spring that spues as shower head 18 is littleNot effective.

The openings of sizes of the path in this pressure retaining parts 16, for example, can calculate approx from Bernoulli's theoremGo out. An example of the calculation method of the effective diameter to pressure retaining parts 16 describes below. Moreover, haveEffect footpath and be man-to-man relation by area, determine either party the opposing party by unique decision, because ofThis describes as basic synonym things in this manual.

Fig. 5 be pattern the present embodiment is described the side of carbonate spring generating apparatus 10 while being connected with water-supply lineThe figure of formula. Water pipe 82 is by water main 80 branches. In addition, water pipe 82 and carbonate spring generating apparatus 10Be connected via the not shown fire hose is first-class. , in the mode of Fig. 5, by the hydraulic pressure of water pipe 82Supply feedwater to carbonate spring generating apparatus 10. Moreover, though in Fig. 5, do not represent, also can be at water pipe82 and carbonate spring generating apparatus 10 between water heater is set, supply with to carbonate spring generating apparatus 10Hot water.

In such mode, the loss of the stream of water pipe 82 and/or not shown water heater etc. is not noCan ignore. Therefore, even be suitable for the situation of the Bernoulli's theorem of the relation that represents throttling and flow,Also need to consider that friction loss is viscous drag. Moreover, for the restriction of carbonate spring generating apparatus 1014, the thickness on the circulating direction of water as thin as a wafer, therefore can be ignored loss. Generally consider friction damageThe Bernoulli's theorem (expansion Bernoulli's theorem) of losing, on certain point, the density of fluid is ρ, flow velocity isV[m/s], pressure is P[Pa], be highly z[m] time, meet

[several 9]

But if usually above-mentioned Reynolds is counted Re in tens of extremely hundreds of scopes, it flows and isLaminar flow is turbulent flow on the contrary more than 1000. In the carbonate spring generating apparatus 10 of the present embodiment, shouldIf flow is considered pipe arrangement footpath etc., Reynolds is counted Re and is exceeded 10000, therefore flowing for rapids of its insideStream. Friction loss (for example, in the example of Fig. 5, B1, B2) in turbulent flow, can be according to experimentallyFormula (7) below obtaining calculates.

[several 10]

At this, λ=0.3164/Re^0.25。

(7) formula of arrangement is

Loss=Bv^1.75

B=f(D, L, ρ, μ)=constant

At this, (8) formula is approximately

Loss ≈ Bv²

If the source pressure of water main 80 is P₁[Pa], water pipe 82 with carbonate spring generating apparatus 10Coupling part is neighbouring (near not shown tap; The 40(of water injection pipe portion is with reference to Fig. 1)) pressureFor P₂[Pa], be B from being responsible for 80 near the loss coefficient above-mentioned tap₁, following formula (9)Relation is set up.

[several 11]

$P_1=\frac{1}{2}{\mathrm{\ρv}}^2+P_2+B_1{v}^2---\left(9\right)$

(9) in formula the right the 1st, be commonly referred to as dynamic pressure item. Fig. 6 is the water pipe different for diameter82 represent the figure of the relation of this flowing pressure and flow L. As judged from Fig. 6, even flowFor 30L/ minute, be for example the pipe that pipe arrangement footpath (diameter) is 12mm, the value of dynamic pressure item mostly is most0.01MPa. On the other hand, hydrostatic pressure is got the such value of for example 0.2MPa, therefore in (9) formulaMiddle dynamic pressure item can be ignored. Moreover, the water supply installation database “ Give of MHLW water device Standard QuasiMeter draws construction method 2.3 Let Meter and makes fixed (the water supply installation program of standards development construction method of water consumption DecisionThe decision of 2.3 design Water usages) " in, illustrate that the water yield of shower is 8～15L/ minute, above-mentionedFlow 30L/ minute corresponding to being far longer than this value, in the situation that having supposed to use shower, far awayHigher than the situation of the hypothesis water yield.

According to more than, flow H[m³/ s] with the pass of loss coefficient and pressure be

P₁≈P₂+B₁v²（10）

?

v²＝(P₁-P₂)/B(11)

Use the tube cofficients k of flow velocity v and flow H conversion, flow H is expressed as

[several 12]

$H=\sqrt{\frac{P_1-P_2}{b_1}},b_1=k{B}_1---\left(12\right)$

And then be conceived to flowing of water in the carbonate spring generating apparatus 10 of the present embodiment. Make carbonate spring rawThe loss coefficient of the flow rate conversion of apparatus for converting 10 is b₂, before the upstream side of next-door neighbour's pressure retaining parts 16Hydraulic pressure is P₃, the relation of water main 80 and water pipe 82 similarly meets

[several 13]

$H=\sqrt{\frac{P_2-P_3}{b_2}}---\left(13\right)$

Relation. At this, water main 80, water pipe 82, carbonate spring generating apparatus 10 are connected as shown in Figure 5Connect, therefore the flow H of formula (12) is identical with the flow H of formula (13).

In addition, owing to representing the left side of formula (6) for Bernoulli's theorem for the front and back of pressure retaining parts 16Limit is equal to each other, and therefore meets

[several 14]

$\frac{1}{2}\mathrm{\ρ}{\left(\frac{4H}{\mathrm{\π}{D_1}^2}\right)}^2+P_3=\frac{1}{2}\mathrm{\ρ}{\left(\frac{4H}{{{\mathrm{\πD}}_2}^2}\right)}^2---\left(14\right)$

Relation. At this, atmospheric pressure=0 of the rear side of pressure retaining parts 16 (downstream). According to above-mentioned (12)Formula, (13) formula and (14) formula, P₂、P₃, H obtains respectively as follows

p₂＝P₁-b₁H²(15)

p3＝P₁-(b₁+b₂)H²

[several 15]

$H^2=\frac{{d_1}^4{d_2}^4{P}_1}{({d_1}^4-{d_2}^4)\mathrm{\ω}+(b_1+b_2){d_1}^4{d_2}^4}---\left(17\right)$

At these ω=8 ρ/π². Solve for d2 on the contrary, obtain as follows

[several 16]

${d_2}^4=\frac{{d_1}^4{H}^2\mathrm{\ω}}{H^2\mathrm{\ω}+{d_1}^4{P}_1-H^2(b_1+b_2){d_1}^4}---\left(18\right)$

The molecule denominator on the right is divided by H², for

[several 17]

${d_2}^4=\frac{{d_1}^4\mathrm{\ω}}{\mathrm{\ω}+\frac{{d_1}^4{P}_1}{H^2}-(b_1+b_2){d_1}^4}---\left(19\right)$

This formula (18) and formula (19), can be used in and be met the such pressure retaining parts of certain flow H 16Effective diameter.

In the pressure P of water main 80₁, or the friction loss of the stream of water, be water pipe 82 specificallyLoss coefficient b₁In situation about generally differing widely because of the value in the water channel of family etc., need to be to meetThe mode of two important documents below, by (15) formula, (16) formula, (19) formula etc., setsThe effective diameter d of pressure retaining parts 16₂。

Important document A: by the hydraulic pressure P of water pipe 82₂More than maintaining authorized pressure.

Important document B: flow H is controlled and becomes specified flow weight range.

At this, the authorized pressure in important document A, referring to can be by gentle to following bubble supply valve 36The control port supply of bubble supply stop valve 34, switches this bubble supply valve 36 and bubble supply stopsThe only minimum hydraulic pressure of the switch of valve 34. In addition, the specified flow weight range in important document B, in view of followingCarbon dioxide generating unit 20 or bubble injection unit 30 in carbon dioxide bubble supply capacity,And/or the length of gas bubble stream 12 etc., will be for realizing the above carbonate spring like that of for example 1000ppmThe CO of generating apparatus 10 desired carbonate springs₂The essential water yield of concentration (is increased to it aboveFor the CO of carbonate spring₂The water yield that concentration ratio required value is low) as the upper limit of flow, and, by dioxyChange the lower limit of the water yield of carbon when roughly saturated in water as flow. The reason of lower limit is set in this wise,Be because if in carbonate spring roughly saturated carbon dioxide bubble shape of thoroughly not dissolving of carbon dioxideBecome air pocket to be present in carbonate spring, wasting cause.

In the present embodiment, pressure retaining parts 16 is thin sheet form, as shown in Figure 7, with as flexibleProperty flexible pipe gas bubble reveal 12 when being connected as the 1st shower head 18 that spues portion, by folderPressure retaining parts 16 connections of living this thin sheet form arrange.
