Detailed description of the invention
Fig. 1 is the working principle diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: shown in Fig. 1, a kind of use described in the utility model
In the single-effect lithiumbromide refrigerator of air separation unit, it is mainly by generator 1, condenser 2, evaporator 3, absorber 4, solution pump
5, cryogenic fluid pump 6, vacuum pump 7, heat exchanger 8, condensate heat exchanger 9 form；
The heater 10 of connection driving heat source, the intermediate bromination in the generator 1 are provided in the generator 1
After lithium solution is heated, vapor enters in the condenser 2 of adjacent connection；
It is provided with the cooler 11 of connection cooling water source in the condenser 2, and keeps the vapor into condenser 2 cold
But at cryogen solution, the cryogen solution forms lithium bromide concentrated solution after water evaporation；The cryogen solution is by throttling
Into connected evaporator liquid-collecting groove 12；
Cryogen solution in evaporator liquid-collecting groove 12 is stamped equably to spray and be located at what is be connected by connected cryogenic fluid pump 6
On cold water heat exchanger tube 13 in evaporator 3, flashes to the vapor of low pressure and enter in the absorber 4 being disposed adjacent；
It is absorbed after dense lithium-bromide solution spray, absorbs the cooled water of heat and take away, dense lithium-bromide solution is dilute in absorber 4
After releasing, successively enter after connected heat exchanger 8,9 re-heat of condensate heat exchanger after the solution pump 5 being connected is boosted
Connected generator 1, high temperature driven steam further cool down in condensate heat exchanger 9 again after being condensed in generator 1
Discharge, completes a refrigeration cycle.
As shown in the figure, a branch in solution pump 5 described in the utility model is automatic into what is be connected by constrictor
Air extractor 14 carries out siphon, and the gas after siphon enters in connected automatic exhaust device 15, controls vacuum by pressure measurement
7 discharge of pump, solution flow into connected 4 lower part of absorber from lower part；
4 high position of absorber is provided with external overflow pipe 16, is connected to one and solution on the overflow pipe 16
The automatic molten brilliant pipe 17 that pump 5 communicates, flows into automatic molten brilliant pipe 17 by overflow pipe 16 after increasing the liquid level of low-pressure absorber 4
Lithium-bromide solution enters 4 bottom of absorber being connected, warp with from the mixed lithium bromide mixed solution of weak solution in solution pump 5
It crosses connected solution pump 5 and squeezes into cryogenic heat exchanger and heat the lithium bromide concentrated solution to come from low-pressure absorber, it is continuous in this way
Crystallization will back and forth be melted.
Single-effect lithiumbromide refrigerator stability described in the utility model is better than electric refrigerator, it should be noted that bromination
Lithium refrigerator needs to consume a certain amount of cooling water, such as the cooling water for needing 226m3/h of 800,000 kilocalories, 2,000,000 kilocalories
Refrigerator needs the cooling water of 566m3/h.
The working principle of lithium bromide refrigerator described in the utility model is: utilization " lithium bromide-water " binary solution is working medium
Right, using lithium-bromide solution as absorbent, using water as refrigerant solution, using water, evaporation endothermic reaches refrigeration purpose in high vacuum,
Complete refrigeration cycle.Such as attached drawing one, mainly by generator, condenser, evaporator, absorber, solution pump, solvent pump, true
The compositions such as empty pump, heat exchanger, condensate heat exchanger.
Its course of work is: the intermediate lithium-bromide solution in generator is heated, water evaporation therein by driving heat source steam
Entering condenser out, the water that is cooled within the condenser is cooled to cryogen solution, and water evaporation therein forms lithium bromide concentrated solution,
Water as refrigerant enters evaporator liquid-collecting groove by throttling and is stamped by cryogenic fluid pump uniformly to spray on cold water heat exchanger tube, flashes to low pressure
Vapor, absorbed after the dense lithium-bromide solution spray that is cooled down from heat exchanger, absorb the cooled water of heat and take away, dense lithium bromide exists
After being diluted in absorber, successively enters after over-heat-exchanger, condensate heat exchanger re-heat after solution pump is boosted and occur
Device, the further cooling discharge in condensate heat exchanger again after high temperature driven steam is condensed in generator, is thus completed
One refrigeration cycle.Automatic gas extraction device in Fig. 1 passes through limit using a branch in solution pump in normal operation
Flow enters automatic gas extraction device and carries out siphon, and the gas after siphon enters in automatic exhaust device, is controlled by pressure measurement true
Sky pump discharge, solution is from lower part inflow absorber lower part.Automatic molten brilliant pipe in figure one is lithium-bromide solution crystallization in order to prevent
It is arranged, lithium-bromide solution is easy crystallization when concentration is high, temperature is low, and passes through the lithium-bromide solution in cryogenic heat exchanger
It is that concentration highest, temperature are minimum, therefore once crystallize, the liquid level that will result in low pressure generator increases, by overflowing after raising
Flow tube flows into automatic molten brilliant pipe, and increases from temperature after the weak solution mixing in solution pump, and the raised lithium bromide mixing of temperature is molten
Liquid enters absorber bottom, and it is dense molten to squeeze into the lithium bromide that cryogenic heat exchanger heating comes from low pressure generator again by solution pump
Liquid constantly will back and forth melt crystallization in this way, to guarantee the continuous service of whole system.
