As depicted in figs. 1 and 2, in gas dissolution apparatus 1, pump 3 is fixed on pallet 2, and dissolving tank 4 is vertical to be installed on pump 3 with putting.Water equal solvent is supplied to dissolving tank 4 by pump 3 under elevated pressure, possesses the sucting 5 of solvent in front.Sucting 5 can be connected with suction pipe arrangement (not shown).In addition, pump 3 possesses spitting unit 6 outstanding upward in upper end.
As shown in Figure 1, dissolving tank 4 possesses inflow part 7 in bottom, and inflow part 7 is connected to the spitting unit 6 of pump 3.Therefore, the solvent supplied by pump 3 flows in dissolving tank 4 from the bottom of dissolving tank 4.In addition, dissolving tank 4 possesses outflow portion 8 in the bottom being positioned at the position different from inflow part 7.Outflow portion 8 is positions that the liquid generated in dissolving tank 4 flows out from dissolving tank 4, is configured in the face side of dissolving tank 4.Outflow portion 8 can be connected with to the outflow pipe arrangement (not shown) supplying target feed fluid.
In addition, in gas dissolution apparatus 1, the gas extended longitudinally attracts pipe arrangement 9 to be connected to the sucting 5 of pump 3.Gas attracts pipe arrangement 9 to be connected to the gas sucting 11 being formed with gas suction port 10 on top.The negative pressure produced by the work because of pump 3, the gas such as air as the dissolving object in dissolving tank 4 is inhaled into from the gas suction port 10 of gas sucting 11, attracts pipe arrangement 9 and be admitted to the sucting 5 of pump 3 via gas.The gas being admitted to sucting 5 mixes as bubble in water equal solvent, generates gas-liquid mixture fluid.This gas-liquid mixture fluid is supplied in dissolving tank 4 via spitting unit 6 and inflow part 7 as fluid.
As shown in Figure 2, be provided with two partition walls in the inside of dissolving tank 4, i.e. the first partition wall 12 and the second partition wall 13, the inside of dissolving tank 4 is divided into gas-liquid mixed groove 14, medial launder 15 and gas-liquid separating tank 16 by the first partition wall 12 and the second partition wall 13.Relative to generate in dissolving tank 4, the flowing of the liquid that is dissolved with gas, gas-liquid mixed groove 14 is positioned at side, most upstream.Medial launder 15 adjoins with the outside of gas-liquid mixed groove 14 and configures.Relative to the flowing of liquid, gas-liquid separation groove 16 is positioned at most downstream side, adjoins with the outside of medial launder 15.
As shown in Fig. 3 (a) (b) (c), the first partition wall 12 and the second partition wall 13 all have roughly cylindric shape.First partition wall 12 divides gas-liquid mixed groove 14 and medial launder 15, extends downwards as shown in Figure 2 from the end face of dissolving tank 4.The lower end of the first partition wall 12 does not arrive the bottom surface of dissolving tank 4, between the bottom surface of dissolving tank 4, be formed with gap.Using the stream of this gap as liquid, gas-liquid mixed groove 14 and medial launder 15 communicate with each other.
Second partition wall 13 divides medial launder 15 and gas-liquid separating tank 16, extends upward from the bottom surface of dissolving tank 4.Second partition wall 13 is arranged to make medial launder 15 surround gas-liquid mixed groove 14 around from outside.In addition, on the top of the second partition wall 13, as shown in Fig. 3 (a) (c) He Fig. 4, its a part of incision is cross section roughly arc-shaped, forms notch 17.Via notch 17, medial launder 15 is communicated with gas-liquid separation groove 16.Notch 17 is configured in the opposition side of outflow portion 8, and outflow portion 8 is positioned at the position left from notch 17.In addition, outflow portion 8 is located at the bottom of gas-liquid separation groove 16, is communicated with gas-liquid separation groove 16.
In such dissolving tank 4, as shown in Figure 2, when gas-liquid mixture fluid is supplied to dissolving tank 4 due to the work of pump 3, gas-liquid mixture fluid is ejected to upward gas-liquid mixed groove 14 through inflow part 7 as shown in Figure 1 from the bottom of dissolving tank 4.End face or first partition wall 12 of gas-liquid mixture fluid and dissolving tank 4 clash into and rebound, and are stranded in the bottom of gas-liquid mixed groove 14 gradually.In addition, the gas-liquid mixture fluid clashing into end face or first partition wall 12 of dissolving tank 4 and rebound collides with the gas-liquid mixture fluid sprayed upward from the bottom of dissolving tank 4, and collide with the liquid level of the gas-liquid mixture fluid being stored in gas-liquid mixed groove 14, stir gas-liquid mixture fluid.Now, the gas mixed through gas attraction pipe arrangement 9 as shown in Figure 1 and the gas being stored in gas-liquid mixed groove 14 in advance mix intensely with water equal solvent, and gas-liquid mixture fluid is stirred, gas is dissolved in solvent under elevated pressure, generates the liquid being dissolved with gas.This process is, by stirring the shearing caused, the gas being mixed in gas-liquid mixture fluid as bubble is segmented, and becomes large with the surface area of solvent contacts, and the concentration of ordinary dissolution of the gas near liquid level reduces owing to stirring the homogenising that causes, and gas rises to the dissolution velocity of solvent.
The liquid generated flows out to medial launder 15 via the gap between the lower end of the first partition wall 12 and the bottom surface of dissolving tank 4.As shown in Fig. 3 (a) (c) He Fig. 4, the liquid flowing out to medial launder 15 flows out to gas-liquid separation groove 16 from notch 17 overflow of the second partition wall 13.In gas-liquid separation groove 16, the gas not being dissolved in liquid completely as bubble from fluid separation applications.Because the flowing of liquid rises near gas-liquid interface, i.e. liquid level, thus bubble is moved upward due to buoyancy.On the other hand, the liquid flowing out to gas-liquid separation groove 16 flows on the direction not hindering such bubble to rise.That is, as shown in Fig. 3 (b) He Fig. 4, liquid flows in the horizontal direction in gas-liquid separation groove 16.The flowing of the horizontal direction of this liquid is along the outer surface of medial launder 15, and in gas-liquid separation groove 16, the liquid of flowing flows out to the outside of dissolving tank 4 from outflow portion 8 in the horizontal direction.Because outflow portion 8 is located at the bottom of gas-liquid separation groove 16, the outflow being thus present in the air pocket near liquid level is suppressed.
Like this, in dissolving tank 4, the second partition wall 13 and outflow portion 8 are arranged so that liquid flows in the horizontal direction along the outer surface of medial launder 15 in gas-liquid separation groove 16, and thus dissolving tank 4 can be miniaturized further, particularly can reduce longitudinal size.Effectively shorten the longitudinal size of dissolving tank 4.And, because outflow portion 8 is arranged on the position left from the notch 17 of medial launder 15, thus can increase the distance for gas-liquid separation, the rise time of bubble can be increased.Liquid flows in the horizontal direction in gas-liquid separation groove 16, thereby, it is possible to during flow undissolved gas from liquid be separated, can carry out gas-liquid separation efficiently.Therefore, it is possible to suppress undissolved gas to flow out to the outside of dissolving tank 4 from outflow portion 8.
In addition, in dissolving tank 4, by the second partition wall 13, be configured to medial launder 15 and surround gas-liquid mixed groove 14 around from outside, thus can suppress the noise easily produced when liquid generates.Moreover because the first partition wall 12 and the second partition wall 13 have cylindric shape, thus the flowing of liquid is homogenized, contributes to the further miniaturization of dissolving tank 4.
In addition, as shown in Fig. 3 (a) (c) He Fig. 4, in gas-liquid separation groove 16, be provided with the vertical rib 18 extended from the end face of gas-liquid separation groove 16 downwards.Vertical rib 18 is formed as strip, and the direction along liquid flow is spaced apart and arrange three.
Fig. 5 represents the mobile schematic diagram that suppress of vertical rib to bubble.
In gas-liquid separation groove 16, the bubble 19 be moved upward in liquid is limited the movement of the horizontal direction to liquid flow by vertical rib 18.Bubble 19 only can rise along the length direction of vertical rib 18, and the multiple bubbles 19 risen like this are fit gradually.Vertical rib 18 also promotes the zoarium of bubble 19.Therefore, non-dissolved gas is separated from efficient liquid, and air pocket can be suppressed to flow out from gas-liquid separation groove 16 to outflow portion 8.Fit bubble 19 arrives liquid level, and undissolved gas is trapped in the top of gas-liquid separation groove 16.In order to the non-dissolved gas on the top by being stranded in gas-liquid separation groove 16 is like this discharged from dissolving tank 4, as shown in Figure 2 and Figure 4, be provided with gas bleeder 20 on the top of the gas-liquid separation groove 16 of dissolving tank 4.
Gas bleeder 20 has buoy (not shown), and this buoy is followed the liquid level of the liquid in gas-liquid separation groove 16 and drifts along, and can move along the vertical direction.Buoy moves up and down with the change of the liquid level of liquid, and thus, gas bleeder 20 carries out releasing and the stopping of the gas being stored in gas-liquid separation groove 16.
In addition, in dissolving tank 4, in order to again utilize the gas being stored in the top of gas-liquid separation groove 16, as shown in Fig. 2 and Fig. 3 (a) (b) (c), be also provided with gas circulation pipe arrangement 21.
Fig. 6 is the fragmentary perspective cross sectional view of the periphery of the gas circulation pipe arrangement represented in dissolving tank.
As shown in Figure 6, the inside of medial launder 15 is located at along the vertical direction by gas circulation pipe arrangement 21, and lower end is connected to the inflow part 7 of dissolving tank 4.As shown in Figure 3 (c), the upper end of gas circulation pipe arrangement 21 bends to roughly arc-shaped along the second partition wall 13, and flatly configures.Gas circulation pipe arrangement 21 is formed by elastomers such as rubber.As shown in Figure 2, the upper end of gas circulation pipe arrangement 21 is configured between the end face of dissolving tank 4 and the top of the second partition wall 13, also works as liner.
Generate be dissolved with the liquid of gas time, near the upper end of gas circulation pipe arrangement 21 and produce pressure differential between lower end.Pressure near the upper end of gas circulation pipe arrangement 21 is higher than the pressure of lower end.In addition, in the inflow part 7 shown in Fig. 6, because the flow velocity of gas-liquid mixture fluid is very fast, be thus depressurized.So the non-dissolved gas being stranded in the top of gas-liquid separation groove 16 is sucked by the upper end from gas circulation pipe arrangement 21, is supplied to inflow part 7 from lower end.The gas sending into inflow part 7 is mixed to gas-liquid mixture fluid again, is dissolved in solvent in gas-liquid mixed groove 14.Like this, owing to being provided with gas circulation pipe arrangement 21 in dissolving tank 4, the gas on the top being stranded in gas-liquid separation groove 16 is supplied to the gas-liquid mixture fluid flowed in dissolving tank 4 by this gas circulation pipe arrangement 21, thus can again utilize non-dissolved gas, and the dissolved efficiency of gas improves.
In addition, gas circulation pipe arrangement 21 is not limited to the inside being located at medial launder 15, can also be located at the inside of gas-liquid separation groove 16.Even if be located at the inside of gas-liquid separation groove 16, gas circulation pipe arrangement 21 also in time being located at medial launder 15 and being inner in the same manner as work.In addition, on the top of dissolving tank 4, as shown in Figure 1, downward-sloping inclination face 22 is formed.By the face 22 that tilts, the air accumulation being stranded in gas-liquid separation groove 16 top, near the central portion of dissolving tank 4, sucks from the gas of gas circulation pipe arrangement 21 upper end and successfully carries out, gas can be supplied to inflow part 7 efficiently.
As depicted in figs. 1 and 2, dissolving tank 4 as above is divided into two parts at the central portion of longitudinal direction, is formed by the upper part 23 of upside and these two parts of lower part 24 of downside.
Fig. 7 is the exploded perspective view of the dissolving tank in the gas dissolution apparatus shown in Fig. 1.Fig. 8 is the exploded perspective view of the dissolving tank in the gas dissolution apparatus shown in Fig. 1.In Fig. 7, Fig. 8, from different directions dissolving tank is shown.
As shown in Figure 7 and Figure 8, in upper part 23, the first partition wall 12 forms, and the first partition wall 12 extends downwards from the end face of upper part 23.In lower part 24, the second partition wall 13 forms, and the second partition wall 13 extends upward from the bottom surface of lower part 24.In lower part 24, be provided with inflow part 7 and outflow portion 8 integratedly in bottom.At the lower end edge portion of upper part 23 and the upper end edge portion of lower part 24, be provided with and give prominence to laterally and the flange part 25,26 of extension.Flange part 25,26 is overlapped, the predetermined portion of flange part 25,26 overlapped, by the fastening upper part 23 of the fixture that bolt, nut etc. are suitable and lower part 24, thus assembling dissolving tank 4 forms and is integrated.When this assembling, the first partition wall 12 is inserted into the inner side of the second partition wall 13, forms gas-liquid mixed groove 14, medial launder 15 and gas-liquid separating tank 16.In addition, as shown in Figure 2, the upper end of the gas circulation pipe arrangement 21 formed by elastomer shown in Fig. 3 (c) sandwiches between the end face of upper part 23 and the top of the second partition wall 13.Due to sandwiching of this gas circulation pipe arrangement 21, gas circulation pipe arrangement 21 works as liner, has water-stop between the end face of upper part 23 and the top of the second partition wall 13.Therefore, it is possible to suppress the part of liquid beyond the notch 17 of the second partition wall 13 to flow out from medial launder 15 to gas-liquid separation groove 16.Realize the water-stop between the end face of so upper part 23 and the top of the second partition wall 13 by the gas circulation pipe arrangement 21 gas being stranded in gas-liquid separation groove 16 top being supplied to dissolving tank 4, thus in dissolving tank 4, number of components reduces.
