Chinese patent application number is 95236138.8 to disclose a kind of " direct combustion lithium bromide cold and hot water machine separated heat supply device ", it is made up of high pressure generator, low pressure generator, condenser, evaporimeter, absorber, high-temperature heat exchanger, low temperature heat exchanger, cryogenic fluid pump, generating pump etc., each one of low pressure generator and condenser, be left and right sides arrangement, evaporimeter and absorber also are each one, are left and right sides arrangement.The condenser of this class formation and low pressure generator have only a contact-making surface, between adding water fender are arranged, and the actual internal area of steam is reduced, and velocity of liquid assets is accelerated, and the circulating resistance of water vapour is bigger, is unfavorable for the thermal efficiency of complete machine.
Chinese patent application number is 92107077.2 to disclose a kind of " coal direct-burning lithium bromide refrigerator ", it is by burner hearth, high pressure generator, low pressure generator, condenser, evaporimeter, compositions such as absorber, the refrigerant vapour that produces in the high pressure generator enters low pressure generator through pipeline, be immersed in its solution on every side by the low pressure generator heating, make it produce refrigerant vapour, this kind structure is that low pressure generator is immersed in the lithium-bromide solution, and utilize low pressure generator pipe endogenous pyrogen to heat, be subjected to the influence of liquid column hydrostatic pressure when in vapour-liquid, separating, the weak effect that water vapour separates from lithium-bromide solution.
The purpose of this utility model is to overcome the deficiency in the above-mentioned prior art, provides a kind of water vapour that helps to separate from lithium-bromide solution, reduces the velocity of liquid assets of refrigerant vapour, reduces resistance, and is highly low, the lithium bromide absorption cold and hot water machine of compact conformation.
For realizing the purpose of this utility model, the lithium bromide absorption cold and hot water machine technology scheme that is provided comprises the condensation cavity, evaporation absorbs cavity, high pressure generator, high-temperature heat exchanger, low temperature heat exchanger, the cryogen canned motor pump, the generator canned motor pump, lithium-bromide solution constitutes, in evaporation absorption cavity, be provided with evaporimeter, absorber, the evaporimeter water pond, middle part at the condensation cavity is provided with low pressure generator, condenser is arranged on the both sides of low pressure generator, between low pressure generator and condenser, be provided with water fender, the condenser water pond is arranged below condenser, and the bottom of low pressure generator is arranged at the end of condenser water pond and condensation cavity.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing one of them embodiment of the present utility model is described in further detail:
As shown in FIG., this lithium bromide absorption cold and hot water machine includes condensation cavity (1), evaporation absorbs cavity (5), high pressure generator (8), high-temperature heat exchanger (9), low temperature heat exchanger (10), cryogen canned motor pump (11), generator canned motor pump (12), lithium-bromide solution (15) formation.
It is negative pressure state that condensation cavity (1) and evaporation absorb in the cavity (5).
In evaporation absorption cavity (5), include evaporimeter (6), absorber (7), evaporimeter water pond (14),
Be provided with low pressure generator (4) at the middle part of condensation cavity (1), condenser (2) is arranged on the both sides of low pressure generator (4), between low pressure generator (4) and condenser (2), be provided with water fender (3), condenser water pond (13) arranged in the below of condenser (2).The bottom of low pressure generator (4) is arranged at the end of condenser water pond (13) and condensation cavity (1).
Condenser (2), low pressure generator (4), evaporimeter (6), absorber (7) are pipe family or the tube bank that copper pipe constitutes.
Evaporation absorbs the bromize lithium dilute solution of cavity (5) bottom and is carried by generator canned motor pump (12), through low temperature heat exchanger (10), behind the heat of absorption from the high temperature bromize lithium concentrated solution in the low temperature heat exchanger (10), enter condensation cavity (1), spray is on low pressure generator (4), the refrigerant vapour heating that bromize lithium dilute solution is flowed in low pressure generator (4) pipe, produce refrigerant vapour, the bottom of low pressure generator (4) is immersed in the lithium-bromide solution again simultaneously, also can heat the lithium-bromide solution that condensation cavity (1) bottom is gathered, the lithium-bromide solution that condensation cavity (1) bottom is gathered is concentrated.
The refrigerant vapour that produces in the condensation cavity (1) enters condenser (2) through water fender (3), and the water quench by flowing in condenser (2) pipe becomes corresponding water as refrigerant with condensing pressure, drops in corresponding two condenser water ponds (13).
Be collected at the water as refrigerant in the condenser water pond (13), entering evaporation after throttling absorbs in the cavity (5), spray is in the tube bank of evaporimeter (6), catch by evaporimeter water pond (14), by cryogen canned motor pump (11) top of the water as refrigerant pumpback in the evaporimeter water pond (14) to evaporimeter (6) constantly sprayed again, absorb the cold water heat in evaporimeter (6) pipe, produce a large amount of refrigerant vapours, produce water at low temperature simultaneously, thereby reach the purpose of refrigeration.
The lithium bromide high temperature concentrated solution of coming out by high pressure generator (8) and condensation cavity (1), through high-temperature heat exchanger (9) and low temperature heat exchanger (10), temperature is passed to by evaporating the low temperature bromize lithium dilute solution that comes out in absorption cavity (5) bottom, enter evaporation after temperature reduces and absorb cavity (5), pouring swashs in the pipe family of absorber (7), by the water quench that in absorber (7) pipe, flows, absorb the refrigerant vapour of flash-pot (6) generation and become bromize lithium dilute solution, be sent to condensation cavity (1) by generator canned motor pump (12) again and high pressure generator (8) concentrates, so just finish a kind of refrigeration cycle.So move in endless cycles, just can constantly export water at low temperature in evaporimeter (6) pipe, for the usefulness of air-conditioning or technology cooling.
The utility model adopts and is provided with low pressure generator at the middle part of condensation cavity, there is condenser on both sides, between be provided with the structure of water fender, make the contact area of refrigerant vapour and condenser increase one times, increased the circulation area of refrigerant vapour, thereby the refrigerant vapour velocity of liquid assets is reduced, and circulating resistance reduces, and has improved the exchange rate that refrigerant vapour becomes water as refrigerant.And the bottom of low pressure generator is arranged at the end of condenser water pond and condensation cavity, make that condenser can also be to the lithium-bromide solution heating of condensation cavity bottom, produce refrigerant vapour, so the lithium-bromide solution in the condensation cavity both can produce refrigerant vapour by spray and concentrate on low pressure generator, again can be by solution heating generation refrigerant vapour is concentrated, form to drench and swash the mode that combines with immersion, promptly help separating of water vapour and lithium-bromide solution, can reduce the height of complete machine structure again.Because refrigerant vapour has two passages and enters condenser, make the refrigerant vapour velocity of liquid assets reduce by one times, significantly reduced the possibility that water as refrigerant is carried the lithium bromide drop secretly, have the efficient height, the advantage of compact conformation.
