Technical field
The utility model relates to lithium-bromide absorption-type refrigerating machine condensation, absorber cooling water cycle art, is a kind of lithium bromide absorption type refrigerator super critical energy saver specifically.
Background technology
Lithium bromide refrigerator originates from U.S. forties in 20th century, is succeeded in developing by doctor Kai Li, and promotes the use of in the whole world.The sixties in 20th century, 704 first the lithium bromide units in China Shanghai are trial-produceed successfully, because the energy-conservation advantage of its uniqueness, use to 21 century in China's large-scale popularization to the initial stage eighties, along with the input of continuous progress in science and technology and scientific research fund, the lithium-bromide absorption-type refrigerating machine power-saving technology has obtained the changes and improvements of making rapid progress.
Though through research and the improvement of decades, still there is a lot of defectives in lithium-bromide absorption-type refrigerating machine aspect energy-conservation, make the lithium-bromide absorption-type refrigerating machine of producing now, the operation of condensation, absorber has dual mode usually:
1, series connection: cooling water is introduced into absorber cooling lithium-bromide solution; Enter condenser condenses high and low temperature refrigerant vapour again, enter cooling tower cooling cool cycles then and use;
2, parallel connection: cooling water enters absorption, condenser simultaneously, enters cooling tower cooling cool cycles then and uses.
These two kinds of methods of operation have directly increased the production and the operating cost of lithium-bromide absorption-type refrigerating machine.Because the inlet temperature of these two kinds of method of operation cooling waters is that 32 ℃, outlet temperature are 37.5 ℃.During the lithium-bromide absorption-type refrigerating machine operation; the out temperature of cooling water is high more; coolant water temperature especially for cooler condenser is high more; consumption to the energy and cooling water is big more, directly causes a large amount of consumption of the energy and water, and refrigerating efficiency reduces; greenhouse gas emissions increase; the circulation that goes round and begins again causes the waste of the energy and water resource, is unfavorable for protecting environment and energy savings.
The utility model content
In order to remedy above-mentioned the deficiencies in the prior art; the utility model provides a kind of lithium bromide absorption type refrigerator super critical cooling and energy conserving device; the lithium-bromide absorption-type refrigerating machine condensation of this device, absorber sub-cooled circularly cooling mode with energy savings and water resource, help protecting environment.
The technical solution of the utility model is: this kind lithium bromide absorption type refrigerator super critical cooling and energy conserving device, comprise condensation, cryogenerator unit and evaporation, absorber unit, the cooling water circulation line is by described condensation, cryogenerator unit and evaporation, absorber unit, it is characterized in that the cooling water of described cooling water circulation line uses low temperature underground water.
The further technical scheme of the utility model is:
For the type of cooling, a kind of scheme is: the low temperature underground water that flows into condensation, cryogenerator unit and evaporation, absorber unit is a circulation line.Another kind of scheme is: low temperature underground water flows into condensation, cryogenerator unit and evaporation, absorber unit respectively by corresponding circulation line.
16-18 ℃ of this underground water water temperature is made up of two low temperature deep wells, a glance water intaking, and a glance nature or pressurization are recharged.Also can use many low temperature deep wells.
The beneficial effects of the utility model are:
Use low temperature underground water to enter condenser, by changing (reduction) condensation temperature and pressure, rapidly the lithium-bromide solution heating is concentrated, the high and low temperature refrigerant vapour of generation is condensed into cryogenic coolant water, enters the evaporator evaporation refrigeration.Use low temperature underground water to enter absorber and cool off dense lithium-bromide solution, by reducing the dense lithium-bromide solution temperature of absorber, change (reduction) evaporating temperature and pressure, improve the operating efficiency of absorber, allow the refrigerant vapour of dense lithium-bromide solution fast Absorption evaporator evaporation under the cryogenic vacuum environment, increase refrigerating capacity; Reduce and make and operating cost, reduce the consumption of the energy and water resource.Inject underground cooling after the low temperature underground water of condensation, absorber heats up, recycle, reduce greenhouse gas emission, the conservation of nature environment.
Its principle is as follows:
Refrigeration needs to consume a large amount of energy, water vapour condensation at normal temperatures usually, and cooling water 32-37.5 ℃, flow one timing of refrigerating capacity and cooling water, the consumption of the energy remains unchanged, and the consumption of cooling water and greenhouse gas emission increase.
If create a lower environment temperature, under vacuum state, allow heated medium heat up rapidly, water at low temperature is cooled off the water vapour condensation rapidly, allow lithium-bromide solution absorb the refrigerant vapour refrigeration of evaporimeter rapidly, the consumption of the energy and water resource and the discharge capacity of greenhouse gases will be reduced significantly.
Lithium-bromide solution is under vacuum state, and with the heating of the lithium-bromide solution in the high-temperature generator, lithium-bromide solution concentrates through heating with natural gas, steam or other energy, produces the high temperature refrigerant vapour; The high temperature refrigerant vapour heats the lithium-bromide solution of cryogenerator again, and the lithium-bromide solution of cryogenerator concentrates through heating, produces cryogenic coolant steam.
Underground low temperature water enters condenser, changed (reductions) condensation temperature and pressure, and the interior refrigerant vapour of high and low temperature generator cools off through condenser, is condensed into water as refrigerant rapidly.
Underground low temperature underground water enters absorber, cools off dense lithium-bromide solution, and fast Absorption steam has changed (reductions) temperature and pressure of evaporimeter has improved absorption efficiency, the refrigerating capacity increase.
The refrigerant vapor in the high cryogenerator of cryogenically having descended water condensation has absorbed the heat of evaporator evaporation and has heated up, and the low temperature underground water after the intensification injects underground cooling through inverted well and recycles.
The lithium-bromide absorption-type refrigerating machine of the utility model production can be widely used in industries such as hotel, hotel, chemical industry, smelting, food, medicine.Production of the present utility model and using method do not have any pollutant emission, help protecting environment, and energy savings and water resource reduce greenhouse gas emission, reduce significantly and make and operating cost.
