Abstract
The utility model relates to a sorption-reverse osmosis type high-efficiency energy-saving refrigerator, which comprises an evaporator (1), an absorber (3), and a separator. The refrigerator is characterized in that the centrifugal separator is a reverse osmosis separator. The reverse osmosis separator replaces the existing evaporation separator, in order to divide dilute solution into thick solution and solvent. The energy consumption is less than the energy consumption required by the evaporation separation, and less than the energy consumption of the compression refrigerator. Therefore, the utility model has excellent energy saving effect and positive effect of environmental protection due to no use of freon.
Description
The utility model relates to a kind of refrigeration machine, is specifically to belong to a kind of absorption-reverse osmosis type high efficiency energy saving refrigeration machine.
Present Absorption Refrigerator, its general mainly is made up of evaporimeter, absorber and heating evaporation separator, the heating evaporation separator comprises generator and condenser.In heating evaporation separated, weak solution was separated into water and concentrated solution, and concentrated solution is imported in the absorber, water then is imported in the evaporimeter, the water vapour that is evaporated out in evaporimeter then is imported in the absorber, is mixed into weak solution with concentrated solution, follows also process thereby finish one.The low temperature that forms when water evaporates in evaporimeter can be used for the purpose of freezing.The refrigeration machine of this structure, its energy consumption rate is bigger.
To be that design is a kind of replace evaporation separator (mainly comprising generator and condenser) in traditional Absorption Refrigerator with the reverse osmosis separation device to the purpose of this utility model, owing to separate with the reverse osmosis separation method, energy consumption of the present utility model the utlity model has good energy-saving effect less than the energy consumption that evaporation separates thereby make.
The utility model can be by the following technical solutions, absorption-reverse osmosis type high efficiency energy saving refrigeration machine is made up of evaporimeter (1), absorber (3), separator, it is characterized in that separator is to adopt a kind of reverse osmosis separation device (9), promptly a kind ofly replace evaporation separator (mainly comprising generator and condenser) in traditional Absorption Refrigerator with the reverse osmosis separation device.
The utility model is in the technique scheme scheme, the original solution inlet of reverse osmosis separation device (9), concentrated solution outlet, water outlet replace weak solution inlet, concentrated solution outlet, the condensation-water drain of evaporation separator in the known technology Absorption Refrigerator respectively, thereby are connected with the weak solution outlet of absorber (3), the concentrated solution inlet of absorber (3), the water inlet of evaporimeter (1) respectively.
The utility model is in such scheme, and reverse osmosis separation device (9) can have the 1-5 level, conspires to create the 1-5 level with pipeline and separates system.Progression is many more, and its solute removal efficiency is high more, and its refrigeration performance is good more.In general, should make that the concentration of solute is no more than 1% in the fresh water.
The utility model is in technique scheme, and evaporimeter (1) is connected with a pipeline, and it imports the raffinate that accumulates in the evaporimeter (1) the original solution arrival end of arbitrary number of level reverse osmosis separation device.
The utility model is in technique scheme, and the fresh water production output of reverse osmosis separation device (9) should be a bit larger tham the consumption of evaporimeter in the known technology Absorption Refrigerator (1) to water, thereby guarantees the requirement of the refrigerating capacity of whole refrigeration machine.Solute concentration does not cross 1% in the fresh water of reverse osmosis separation device (9) output, and reverse osmosis separation device (9) should have good air-tightness.
The utility model is compared with existing compression refrigerating machine, and its energy consumption is smaller, and good energy-saving effect is arranged, and it does not use freon refrigeration working medium, and environmental protection is had good effect.
Fig. 1 is the utility model principle schematic.
Provide an embodiment of the present utility model below in conjunction with accompanying drawing:
Select one the cover existing refrigerating capacity be 500,000 kilocalories/hour lithium-bromide absorption-type refrigerating machine, and to select two cover fresh water yields for use be existing product reverse osmosis separation device more than 1.5 tons/hour, wherein the operating pressure of reverse osmosis separation device is 12～15MPa, include high-pressure pump, should check whether the reverse osmosis separation device has good air-tightness.
As shown in Figure 1, the utility model is made up of evaporimeter (1), pipeline (2), absorber (3), pipeline (4), valve (5), valve (6), prime reverse osmosis separation device (7), back level reverse osmosis separation device (8).In the frame of broken lines is reverse osmosis separating apparatus (9).
Evaporation separator partly (mainly comprising generator and condenser) in the traditional lithium bromide refrigerator of amputation, make it to remain with absorber (3), evaporimeter (1), to stay the dense lithium-bromide solution outlet of generator after the amputation, the inlet of rare lithium-bromide solution, and the delivery port of condenser.The mouth of a river.
Two cover reverse osmosis separation devices are installed in series, and the water outlet of prime reverse osmosis separation device (7) is connected with the original solution inlet of back level reverse osmosis separation device (8).
The original solution inlet of prime reverse osmosis separation device (7), rare lithium-bromide solution inlet of traditional evaporation separator will be replaced, be connected with the weak solution outlet of absorber (3), the concentrated solution outlet of prime reverse osmosis separation device (7), to replace the dense lithium-bromide solution outlet of tradition evaporation separator, be connected with the dense lithium-bromide solution inlet of absorber (3).The water outlet of back level reverse osmosis separation device (8) replaces the condensation-water drain of traditional evaporation separator, is connected with the water inlet of evaporimeter (1).The concentrated solution outlet of back level reverse osmosis separation device (8) instead is connected from the weak solution input of device (7) with the prime counter-infiltration.
In evaporimeter (1), connect a pipe, make it the raffinate that accumulates in the evaporimeter (1) can be caused the original solution inlet of back level reverse osmosis separation device (8).
In the connection procedure of whole system, should guarantee good air-tightness.
In the refrigeration working medium of lithium bromide-water, should add HBr, it is about 6 that the acid-base value of solution is adjusted to pH value.
Claims (3)
1, a kind of absorption-reverse osmosis type high efficiency energy saving refrigeration machine, form by evaporimeter (1), absorber (3), separator, it is characterized in that separator is a kind of reverse osmosis separation device (9), the original solution of reverse osmosis separation device (9) inlet, concentrated solution outlet, water outlet respectively with the outlet of absorber (3), the concentrated solution inlet of absorber (3), the inlet of evaporimeter (1) are connected.
