(embodiment one)
With reference to Fig. 1, Fig. 2, Fig. 3 A and Fig. 3 B, be described for the gas dissolution apparatus 1 in the embodiment of the present invention one below.Fig. 1 is the perspective diagram of gas dissolution apparatus (hereinafter referred to as dissolver) 1, Fig. 3 A is the representative side section view of the gas dissolution apparatus of plane along the central axis L in Fig. 1, and Fig. 3 B is the cross sectional representation of the dissolver 1 along C-C line in Fig. 3 A.On the other hand, Fig. 2 is the schematic diagram of the bathtub system 2 that have employed dissolver 1.Can in dissolver 1 fluid-mixing (hereinafter referred to as " fluid ") of injecting gas and liquid, by gas dispersion with dissolve in a liquid, and the liquid being dissolved with gas is discharged.
Dissolver 1 comprises circular tube shaped container 15, and this circular tube shaped container 15 comprises the cylindrical sidewalls 13 having and be roughly circular cross section, and the end wall 14 of the ends A be used on the length direction (central axis L direction) of sealing sidewall 13 and B.Circular tube shaped container 15 is placed in the position of inclination, and its central axis L favours horizontal direction, or forms the angle theta of 10 to 40 ° with horizontal direction M.Above-mentioned for preferred angular configurations scope is to reach desirable effect, namely while promotion gas dissolves in a liquid and avoids fluid to discharge from tubular container 15, in liquid, gas exists with the form of a large amount of undissolved air pocket.As long as it should be noted that the position tilted contributes to reaching desirable effect, the angle outside above-mentioned angular configurations scope can be adopted.
Comprise in tubular container 15 or store gas, as the air as solute, and liquid, as the water as solvent.The combination of other suitable gas any and liquid also can be used as solute and solvent.Between gas and liquid, form an interface 6, its central point is generally within the center of sidewall 13 length direction of tubular container 15.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.At the inner surface on sidewall 13 top, interface 6 or the position on interface 6 are provided with gas vent 18.
Further, tubular container 15 has inlet 11 on sidewall 13, to inject fluid wherein.Can be found out by cross sectional representation in Fig. 3 B, inlet 11 is arranged on the bottom of sidewall 13 or tubular container 15, is same as or lower than the position of interface 6.Consider the efficiency of gas and liquid agitation, preferably, inlet 11 is arranged at the horizontal level 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 tubular container 15, the bottom near liquid storage district 62 on the sidewall 13 of tubular container 15 is provided with liquid outlet 12 further, and described discharge pipe 17 is connected to outlet 12.
With reference to Fig. 2, bathtub system 2 is described.Have employed dissolver 1 in bathtub system 2, comprise bathtub 21; Pump 3, for sending the liquid that draws into dissolver 1 to draw liquid in bathtub 21; Venturi tube 4, is arranged between dissolver 1 and bathtub 21, for discharging or reducing the pressure coming from liquid in gas dissolution apparatus 1.Pump 3 can adopt centrifugal pump.The end that pumps into of pump 3 is connected with the outlet 22 of bathtub 21 by pipe 51, and the end that pumps of pump 3 is connected with the inlet 11 of dissolver 1 by pipe 52.On the other hand, the liquid outlet 12 of dissolver 1 is connected by the entrance of pipe 53 with Venturi tube 4, and the outlet of Venturi tube 4 is connected with the entrance 23 of bathtub 21 by pipe 54.The edge part 24 of bathtub 21 has air suction inlet 25.Air suction inlet 25 is connected to the intermediate point of pipe 52 by pipe 55 and pipe 56.The junction of pipe 55 and pipe 56 being provided with check-valves 57, flowing to air suction inlet 25 for stoping liquid from pipe 52.
In bathtub system 2, pump 3 pumps into the liquid bathtub 21 from the outlet 22 of bathtub 21, the liquid pumped into is sent into dissolver 1 by pipe 52.Meanwhile, 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 pipe 52, to make gas dispersion and to dissolve in a liquid.The fluid being dissolved with gas is sent to Venturi tube 4 by pipe 52, to reduce the pressure (internal pressure) of liquid, thus when fluid is injected in the liquid in bathtub 21 by entrance 23, mixing gas in a fluid generates trickle bubble in a liquid.
Below the function of dissolver 1 is described.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 sidewall 13, is same as or lower than the horizontal level of interface 6.Thus, from the fluid of inlet 11, as injection stream, deceleration can be unlikely by effectively injecting tubular container 15, and collide with the top of sidewall 13 inner surface, splash, formation eddy current.Then, fluid and interface 6 collide and merge with liquid in liquid storage district 62.
Merge during this period of time from the top liquid collided fluid and liquid storage district 62 of fluid and sidewall 13 inner surface, fluid drifts about to transience in atmosphere storage district 61 with the form of drop.Drift about in this transience, increase the surface area of fluid, promote or accelerate gas dissolving in a liquid in fluid.Because the center of interface 6 is generally within the center of length direction on the sidewall 13 of tubular container 15, atmosphere storage district 61 has enough large space to promote the dissolving of gas.Injecting the process being injected into the fusion of fluid and liquid of fluid from inlet 11, fluid has effectively been carried out stirring to make in gas dissolution liquid in a fluid.On the other hand, the liquid in fluid storage district 62 is not only stirred by the collision of fluid and liquid, and is passed through effectively to be stirred by the injection of inlet 11 to the fluid of tubular container 15.
According to said method, in tubular container 15 store or occur fluid or liquid in, gas is disperseed and is dissolved in a fluid, and, due to the stirring of fluid self and by inlet 11 by the injection process of fluid injection conduit shape container 15 to the stirring of liquid in tubular container 15 and the collision between fluid and liquid, facilitate the dissolving of gas in tubular container 15 inner fluid and liquid.Specifically, be by increasing the surf zone of bubble and liquid comes into contact and suppress the solubility of gas near gas and liquid interface 6, promoting gas dissolving in a liquid.
The surf zone increasing bubble is realized by stirred fluid and liquid, because can produce a shearing force to each bubble in fluid and liquid, to split bubble (air) to the stirring of fluid and liquid.Gas solubility in a liquid near liquid interface 6 is suppressed to be by realizing the stirring of liquid, because to the stirring of liquid, the solubility of gas in balanced liquid, so also just the balanced gas that caused in the liquid away from interface 6 by gas dissolution of inhibit in the increase of interface 6 or the liquid upper solubility near interface 6, the simultaneously also balanced solubility of gas in liquid bottom.
The liquid storage district 62 of tubular container 15, stores the liquid being dissolved with gas of the method acquisition of being dissolved in a liquid by above-mentioned promotion gas.Still may can there is many undissolved bubbles in the liquid in liquid storage district 62.But these bubbles are not almost present in bottom or the bottom in liquid storage district 62, but are mostly present in the upper area in liquid storage district 62.Thus by liquid outlet 12 and discharge pipe 17, dissolver 1 will be dissolved with gas not containing the liquid discharge tube shape container 15 (sending into pipe 53) of air pocket bottom liquid storage district 62.
According to the present embodiment, the tubular container 15 of dissolver 1 is placed in the position of inclination, and its central axis L tilts relative to horizontal direction M.The lateral attitude of tubular container 15 adds the region of the interface 6 in tubular container 15 between gas and liquid, thus add the efficiency that liquids and gases mix stirring, to reach the object strengthening gas dissolving in a liquid, meanwhile, liquid storage district 62 is wherein made to keep enough dark liquid level to discharge from tubular container 15 to avoid bubble.
Otherwise if tubular container 15 is placed in the length direction position parallel with horizontal direction M, in liquid storage district 62, the liquid level of storage of liquids is lower, as only reached the radial location of tubular container 15 cross section.Although at this moment form the junctional area 6 that extends to whole tubular container 15 between gas and liquid, provide enough junctional area 6 to promote gas dissolving in a liquid, but gas-liquid mixture fluid does not probably just disperse fully at gas and dissolves in a liquid, or when in liquid, existence does not dissolve air pocket in a large number, discharge from tubular container 15.
In addition, if tubular container 15 is placed in its length direction position vertical with horizontal direction M, the junctional area 6 formed between gas and liquid is less, the maximum transverse cross-sectional area being about tubular container 15; Although at this moment the liquid level in liquid storage district 62 is enough to stop, be discharged when gas-liquid mixture fluid exists a large amount of air pocket in a liquid, gas mixing in a liquid and dissolved efficiency lower.Comparatively speaking, from the above mentioned, the tubular container 15 that the embodiment of the present invention one provides has lateral attitude, and junctional area 6 is enough large, and the liquid level in liquid storage district 62 is also enough dark, can improve the efficiency of fluid chemical field and stirring, stops air pocket to be discharged.Further, dissolver 1 is tied enough simple, cheap for manufacturing cost; Volume is little, low to requirements of installation space.
Referring to Fig. 4 to Fig. 7, the improvement embodiment of dissolver 1 in enforcement one is described, wherein, Fig. 4 is for improving embodiment one schematic diagram, Fig. 5 A and Fig. 5 B is for improving embodiment two schematic diagram, Fig. 5 C is the embodiment of the improvement again schematic diagram improving embodiment two, Fig. 6 A and Fig. 6 B is for improving embodiment three schematic diagram, and Fig. 7 is for improving embodiment four schematic diagram.Below main to improvement embodiment in the feature different from basic embodiment be described.Corresponding to Fig. 3 A, the dissolver 1a representative side section view that Fig. 4 provides for improving embodiment one.
See Fig. 4, the inlet tube 16a of dissolver 1a is connected to inlet 11, favours the direction vertical with the sidewall 13 of tubular container 15, thus close to the end A in atmosphere storage district 61 in tubular container 15.By inlet tube 16a by inlet 11, along the fluid that the end A towards tubular container 15 instead of the direction perpendicular to sidewall 13 inject, collide with the respective regions on sidewall 13 inner surface top, this region is positioned at the bearing of trend of inlet tube 16 (or its axis), compared with the basic embodiment in the embodiment one shown in Fig. 1 and Fig. 3 A, 3B, more close to the end A of dissolver 1 in embodiment one.
Fluid injects the tubular container 15 of dissolver 1a by inlet 11, and colliding with region sidewall 13 inner surface being positioned at ascending pipe 16a extension line direction hits splash.Then, fluid and interface 6 collide, and merge with the liquid in liquid storage district 62.The liquid bumped against in fluid and liquid storage district 62 of colliding from fluid and sidewall 13 inner surface upper area merge mutually during this period of time in, similar to the situation in dissolver in basic embodiment 1, fluid drifts about to transience in atmosphere storage district 61 with the form of drop.Improve in embodiment one, the inlet tube 16a in dissolver 1a favours the direction of vertical sidewall 13, thus makes the region that in dissolver 1a, fluid and sidewall 13 inner surface top collide, and is greater than the respective regions in dissolver 1.Compared with the situation in dissolver 1, the region that drop drifts about in the atmosphere storage district 61 of dissolver 1a is wider, facilitates gas dissolving in a liquid in fluid.
With reference to Fig. 5 A and Fig. 5 B, the dissolver 1b that modified embodiment two provides is described.Corresponding to Fig. 3 A, Fig. 5 A is the representative side section view of dissolver 1b, and Fig. 5 B is the cross sectional representation of the dissolver 1b along C-C line in Fig. 5 A.As shown in the figure, the sidewall 13 of dissolver 1b is provided with inlet 11b.As in Fig. 5 B perpendicular to shown in the cross section in central axis L direction, have skew between the position of inlet 11b and the bottom of sidewall 13 or tubular container 15.Inlet tube 16b is connected to inlet 11b, parallel with the direction that inlet tube in Fig. 3 B 16 extends with Fig. 3 A.
