Abstract
A dissolving apparatus (1) has a cylindrical tubular container (15) closed at both ends with its center axis being inclined to the horizon. A center of an interface (6) between a gas and a liquid in the container (15) is positioned at a center in a lengthwise direction of a side wall (13) of the container (15). Two inner spaces of the container (15) above and below the interface are referred to as a gas section (61) and a liquid section (62). An injection inlet (11) for injecting a gas-liquid mixed fluid into the container (15) is provided at a level corresponding to, or lower than, the interface (6). A liquid outlet (12) for discharging the liquid is provided near a bottom of the liquid section (62) of the container (15). Since the container (15) is inclined, the interface (6) can have an area large enough to promote dissolution of the gas into the liquid. Since the depth of the liquid in the liquid section (62) is sufficiently deep, the liquid can be prevented from being discharged through the liquid outlet (12) with large gas bubbles being present therein.

(embodiment one)
With reference to Fig. 1, Fig. 2, Fig. 3 A and Fig. 3 B, be that example is described with the gas dissolution apparatus in the embodiment of the invention one 1 below.Fig. 1 is the perspective diagram of gas dissolution apparatus (hereinafter to be referred as dissolver) 1, and Fig. 3 A is that Fig. 3 B is the cross sectional representation along the dissolver 1 of C-C line among Fig. 3 A along the representative side section view of the gas dissolution apparatus on the plane of passing through the central axis L among Fig. 1.On the other hand, Fig. 2 is the schematic diagram that has adopted the bathtub system 2 of dissolver 1.Can be in dissolver 1 fluid-mixing (hereinafter to be referred as " fluid ") of injecting gas and liquid, with gas dispersion be dissolved in the liquid, and the liquid that will be dissolved with gas discharges.
Comprise in the tubular container 15 or store gas, as air as solute, and liquid, as water as solvent.The combination of any other suitable gas and liquid also can be used as solute and solvent.Form an interface 6 between gas and liquid, its central point is positioned at the center of sidewall 13 length directions of tubular container 15 substantially.Be atmosphere storage district 61 in the part of interface more than 6 in the inner space of tubular container 15, interface 6 and following part thereof are liquid storage district 62.Inner surface on sidewall 13 tops is provided with gas vent 18 near interface 6 or the position on interface 6.
Further, tubular container 15 has inlet 11 on sidewall 13, with to wherein injecting fluid.Can find out that by cross sectional representation among Fig. 3 B inlet 11 is arranged on the bottom of sidewall 13 or tubular container 15, be same as or be lower than the position of interface 6.Consider the efficient of gas and liquid agitation, preferred, inlet 11 is arranged at the horizontal level that is lower than interface 6.Ascending pipe 16 is connected to inlet 11, and extends along the direction vertical with the central axis L of sidewall 13 or tubular container 15.In order to discharge the liquid in the tubular container 15, the bottom near liquid storage district 62 on the sidewall 13 of tubular container 15 further is provided with liquid outlet 12, and described discharge pipe 17 is connected to outlet 12.
With reference to Fig. 2 bathtub system 2 is described.Adopt dissolver 1 in the bathtub system 2, comprised bathtub 21; Pump 3 is used for sending into dissolver 1 to bathtub 21 draw liquids and with the liquid that draws; Venturi tube 4 is arranged between dissolver 1 and the bathtub 21, is used for discharging or reducing the pressure that comes from gas dissolution apparatus 1 liquid.Pump 3 can adopt centrifugal pump.The end that pumps into of pump 3 links to each other with the outlet 22 of bathtub 21 by pipe 51, and the end that pumps of pump 3 links to each other with the inlet 11 of dissolver 1 by managing 52.On the other hand, the liquid outlet of dissolver 1 12 links to each other with the inlet of Venturi tube 4 by pipe 53, and the outlet of Venturi tube 4 links to each other with the inlet 23 of bathtub 21 by managing 54.The edge part 24 of bathtub 21 has air suction inlet 25.Air suction inlet 25 by manage 55 and pipe 56 be connected to pipe 52 intermediate point.Junction at pipe 55 and pipe 56 is provided with check-valves 57, is used to stop liquid to flow to air suction inlet 25 from managing 52.
In bathtub system 2, pump 3 pumps into liquid the bathtub 21 from the outlet 22 of bathtub 21, and the liquid that pumps into is sent into dissolver 1 by managing 52.Simultaneously, air is inhaled into pipe 52 by air suction inlet 25.Accordingly, the fluid-mixing of gas and liquid is injected into dissolver 1 from managing 52, so that gas dispersion and being dissolved in the liquid.The fluid that is dissolved with gas is sent to Venturi tube 4 by managing 52, reducing the pressure (internal pressure) of liquid, thereby when fluid by 23 liquid that are injected in the bathtub 21 that enter the mouth in the time, the gas that is blended in the fluid generates trickle bubble in liquid.
Function to dissolver 1 is described below.In tubular container 15, liquid storage district 62 and gas memory block 61 have liquids and gases respectively, and fluid injects tubular container 15 by inlet 11.From the above mentioned, inlet 11 is arranged in the sidewall 13, is same as or is lower than the horizontal level of interface 6.Thereby, from the fluid of inlet 11,, can effectively be injected tubular container 15 and be unlikely deceleration as injecting stream, and with top collision, the splash of sidewall 13 inner surfaces, form eddy current.Then, fluid and interface 6 collisions and 62 merge with liquid in the liquid storage district.
Collide during liquid fluid and the liquid storage district 62 merges during this period of time from the top of fluid and sidewall 13 inner surfaces, fluid is with form transience ground drift in atmosphere storage district 61 of drop.In the drift of this transience ground, increased the surface area of fluid, promote or quickened the dissolving of gas in liquid in the fluid.Because the center of interface 6 is positioned at the center of length direction on the sidewall 13 of tubular container 13 substantially, there is the dissolving of enough big space promotion gas in atmosphere storage district 61.Injecting the process of the fusion that is injected into fluid and liquid of fluids from inlet 11, fluid has effectively been carried out stirring so that gas is dissolved in the liquid in the fluid.On the other hand, the liquid in the fluid storage district 62 not only is stirred by the collision of fluid and liquid, and quilt is by effectively being stirred to the injection of the fluid of tubular container 15 by inlet 11.
According to said method, in the fluid or liquid of in tubular container 15, storing or occurring, gas is disperseed and is dissolved in the fluid, and, because the stirring of convection cell self and the injection process of fluid being injected tubular container 15 by inlet 11 have promoted the dissolving of gas in tubular container 15 inner fluids and liquid to the stirring of tubular container 15 liquid and the collision between fluid and the liquid.Specifically, be by increasing surf zone and inhibition gas and near liquid interface 6 Gas Solubility that bubble contacts with liquid, promoting the dissolving of gas in liquid.
The surf zone that increases bubble is realized by stirred fluid and liquid, because each bubble in the stirring meeting convection cell of convection cell and liquid and the liquid produces a shearing force, so that bubble (air) is cut apart.Suppressing near liquid interface 6 solubility of gas in liquid is to realize by the stirring to liquid, because stirring to liquid, balanced Gas Solubility in the liquid, so also just balanced the inhibition is dissolved in the gas that causes in the liquid away from interface 6 at interface 6 or near the increase of the liquid upper solubility of interface 6 by gas, the also balanced simultaneously solubility of gas in the liquid bottom.
The liquid storage district 62 of tubular container 15, the liquid that is dissolved with gas that the method that storage is dissolved in liquid by above-mentioned promotion gas obtains.May still can there be many undissolved bubbles in liquid in the liquid storage district 62.But these bubbles almost are not present in the bottom or the bottom in liquid storage district 62, but mostly are present in the upper area in liquid storage district 62.Thereby by liquid outlet 12 and discharge pipe 17, dissolver 1 is dissolved with the liquid discharge tube shape container 15 (sending into pipe 53) that gas does not contain air pocket with 62 bottoms, liquid storage district.
According to present embodiment, the tubular container 15 of dissolver 1 places the position of inclination, and its central axis L tilts with respect to horizontal direction M.The lateral attitude of tubular container 15 has increased the zone of the interface 6 between the gas and liquid in the tubular container 15, thereby increased the efficient that liquids and gases mix stirring, to reach the purpose that strengthens the dissolving of gas in liquid, simultaneously, make liquid storage district 62 wherein keep enough dark liquid level from tubular container 15, to discharge to avoid bubble.
Otherwise if tubular container (15) places length direction and the parallel position of horizontal direction (M), the liquid level of storage of liquids is lower in liquid storage district (62), as only reaching the radial location of tubular container (15) cross section.Although at this moment form a junctional area (6) that extends to whole tubular container (15) between gas and the liquid, provide enough junctional area (6) to promote the dissolving of gas in liquid, yet gas-liquid mixture fluid does not just disperse fully and is dissolved in the liquid at gas probably, or existence is not dissolved under the situation of air pocket in a large number in the liquid, discharges from tubular container (15).
In addition, if tubular container (15) places its length direction and the vertical position of horizontal direction (M), the junctional area that forms between gas and the liquid (6) is less, and maximum is about the transverse cross-sectional area of tubular container (15); Although at this moment the liquid level of liquid storage district (62) is enough to stop, gas-liquid mixture fluid exists in liquid under the situation of a large amount of air pockets and is discharged from, and mixing and the dissolved efficiency of gas in liquid is lower.Comparatively speaking, from the above mentioned, the tubular container 15 that the embodiment of the invention one provides has lateral attitude, and junctional area 6 is enough big, and the liquid level in the liquid storage district 62 is also enough dark, can improve the efficient that fluid mixes and stirs, and stops air pocket to be discharged from.Further, dissolver 1 knot is enough simple, cheap for manufacturing cost; Volume is little, and is low to requirements of installation space.
Below with reference to Fig. 4 to Fig. 7 the improvement embodiment of implementing dissolver 1 in is described, wherein, Fig. 4 is for improving embodiment one schematic diagram, Fig. 5 A and Fig. 5 B are for improving embodiment two schematic diagrames, Fig. 5 C is for improving the embodiment of the improvement once more schematic diagram of embodiment two, Fig. 6 A and Fig. 6 B are for improving embodiment three schematic diagrames, and Fig. 7 is for improving embodiment four schematic diagrames.Below mainly the feature different with basic embodiment is described in the embodiment to improving.Corresponding with Fig. 3 A, Fig. 4 is for improving the dissolver 1a representative side section view that embodiment one provides.
