Description
Technical field
The present invention relates to single pressure absorption-type refrigeration technology and equipment, be specifically related to a kind of air lift pump that has the bubble gathering-device.
Background technique
Press in the absorption refrigeration system single, air lift pump is worked under the two phase flow state, produces enough density of heat flow raties to evaporate the ammonia in the pump line and to form bubble through the external heating equipment in vertical-lift pipe bottom; Bubble rises in pipe and promotes the high-order cistern of flow direction; Therefore simultaneously, the density of the gas-liquid mixture in the riser is littler than the middle density of liquid of generator (being the low level liquid-storage container), can produce enough uplifts and will manage interior two-phase fluid and rise to certain height.Present research points out that the two phase flow in the riser flows through when crossing to bulk at slug flow or by slug flow, and the transfer efficiency of air lift pump is the highest, and the amount of liquid that promptly unit time promoted is maximum.
Yet; Subject matter and shortcoming that present air lift pump exists are: one, owing to heat in vertical-lift pipe bottom, the bubble of generation carries out the transition to the bullet shape from blister earlier; Can not guarantee that two phase flow is in work under the slug flow always in the riser, the efficient of air lift pump is lower; Two, the air lift pump poor work stability receives the influence of thermal source grade bigger, and when under unstable thermal source, moving, the amount of liquid that air lift pump promotes is unsecured; Three, the scope of application is restricted, and need utilize low-grade heat source through double heat transmission equipment, and thermal loss is bigger, and has increased the input of equipment, and Economy descends.
In sum, the air lift pump working efficiency is relatively poor at present, and can not directly utilize low-grade unstable thermal source, demands researching and developing a kind of air lift pump that promotes the efficient height, can directly utilize low-grade unstable thermal source to drive urgently.
Summary of the invention
The present invention be directed to existing air lift pump exists in application process: efficient is low, job insecurity and can not directly utilize shortcoming such as the low unstable thermal source of article, and the Eight characters structure of employing overlapping is carried out the collection of bubble and the water conservancy diversion of liquid.The present invention not only can directly utilize low-grade unstable thermal source, reduces energy loss, and can when directly utilizing low-grade heat source, make the air lift pump stable performance, and promoting amount of liquid obviously increases.
A kind of air lift pump that has the bubble gathering-device; It is characterized in that: air lift pump riser bottom is connected with the low level liquid-storage container; Said low level liquid-storage container is connected to generator; Low level liquid-storage container set inside has heat exchanger, and heat exchanger is connected with extraneous thermal source, and the position vertical with heat exchanger is connected with the bubble gathering-device above said heat exchanger.
Described low level liquid-storage container top is Eight characters structure, plays guide functions; The bubble gathering-device is fixed in low level liquid-storage container inwall through three fins.
Described bubble gathering-device bottom is Eight characters structure, and top is connected with the outlet mouth of pipe, and its effect is to collect bubble.
The Eight characters structure of the gentle bubble gathering-device of the Eight characters structure bottom on low level liquid-storage container top is parallel to each other, to reduce flow resistance.
One " foyer " that this bubble gathering-device is progressively grown up just as bubble; Get into riser after reaching certain pressure; Thereby guarantee that the air lift pump riser remains on work under the slug flow always; And, both improved the working efficiency of air lift pump without the transformation of other flow pattern, reduce the input of heat again.
The present invention has the air lift pump of bubble gathering-device, can form stable slug flow in riser inside, because in the low level liquid-storage container; Low-grade unstable thermal source forms bubble through heat exchanger heats liquid, because the speed that bubble forms is very fast, and bubble gathering-device open upper end is less; Make bubble in the bubble gathering-device, gather, bubble gathering-device pressure raises, along with the rising of pressure; The speed that bubble is overflowed improves; After reaching certain pressure, the speed that bubble is overflowed reaches balance with the speed of bubble formation, thereby forms stable bubble.
The present invention has low-grade unsettled thermals source such as waste heat used heat that driving heat source that the air lift pump of bubble gathering-device adopts is a factory, solar energy, and can directly utilize this type thermal source to make system reach stable.
Advantage and the good effect that has the air lift pump of bubble gathering-device of the present invention is:
1, the amount of liquid that riser is promoted in the unit time reaches maximum, has improved the efficient of air lift pump;
2, can directly use low-grade unstable thermal source, capacity usage ratio improves greatly, has enlarged the scope that thermal source utilizes;
3, because riser always in efficient work down, has reduced heating power, practiced thrift the energy;
4, simple in structure, cost is low and efficient is high, has reduced economic input, makes things convenient for marketing.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail,, but present embodiment is not limited to the present invention, and every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.
A kind of air lift pump that has the bubble gathering-device, as shown in Figure 1, comprise riser 4, bubble gathering-device 3 and low level liquid-storage container 1; Air lift pump riser 4 bottoms are connected with low level liquid-storage container 1; Said low level liquid-storage container 1 is connected to generator, and low level liquid-storage container 1 set inside has heat exchanger 2, and heat exchanger 2 is connected with extraneous thermal source; Above said heat exchanger 2, the position vertical with heat exchanger is connected with bubble gathering-device 3.Described low level liquid-storage container 1 top is Eight characters structure, plays guide functions; Bubble gathering-device 3 is fixed in low level liquid-storage container 1 inwall through three fins.Described bubble gathering-device 3 bottoms are Eight characters structure, and top is connected with the outlet mouth of pipe, and its effect is to collect bubble.The Eight characters structure of the gentle bubble gathering-device of the Eight characters structure on low level liquid-storage container 1 top 3 bottoms is parallel to each other, to reduce flow resistance.Described heat exchanger 2 is arranged on the below of bubble gathering-device 3, and the bubble of formation can be accumulated in the trap.
In the single pressure absorption-type refrigeration system, the ammoniacal liquor dilute solution after finishing gets into low level liquid-storage container 1 by the bottom connecting pipeline, is further heated by the heat exchanger 2 in the low level liquid-storage container 1, and the most of ammonia in the dilute solution is heated to seethe with excitement and produces bubble.During beginning, because the speed that bubble forms is very fast, and the outlet of the upper end of bubble gathering-device 3 is less; The bubble that produces has little time to overflow, and small bubble slowly gather in the gas storage chamber of bubble gathering-device 3 earlier, along with the rising of pressure; The speed of overflowing improves, and the gas content in the riser 4 is also increasing, reach certain pressure after; The speed that speed that bubble forms and bubble are overflowed reaches balance, thereby forms stable bubble, in riser 4, forms stable slug flow simultaneously.Then constantly overflow and play the shape bubble in the upper end of bubble gathering-device 3, bubble promotes liquid and arrives high-order liquid-storage container 5 in uphill process.Because the density of the gas-liquid mixture in the riser 4 is lower than density of liquid in the low level liquid-storage container 1, therefore produces enough pressure differences and promote in the liquid entering riser 4 in the low level liquid-storage container 1.
