Abstract
The utility model relates to a device for preventing lithium bromide crystals from being polluted by low load coolant water for a lithium bromide refrigerator. An inlet pipe of a connecting pipe of cooling water is sequentially connected with an absorber, a condenser and an outlet pipe, the outlet pipe of the cooling water connected with the condenser is provided with a three-way stepping valve, the three-way stepping valve is connected between the inlet pipe of the cooling water and the absorber, one end of the three-way stepping valve is connected with the condenser, the other end is connected with the outlet pipe of the cooling water, and three controllers provided with temperature are connected with the three-way stepping valve. The condensing temperature and the normal full load are ensured to be the same and are not changed no matter how the temperature of the cooling water and the load are changed. The concentration of concentrated solutions of the generator and the condensing pressure are not changed, and crystals of the concentrated solutions and the coolant water are not polluted.
Description
The utility model belongs to the lithium-bromide absorption-type refrigerating machine device, and particularly a kind of lithium bromide refrigerator prevents underload refrigerant pollution lithium bromide crystallization apparatus.
The lithium-bromide absorption-type refrigerating machine group is in actual moving process at present, and regular meeting runs into refrigerant pollution, the problem of concentrated solution crystallization.Cause the reason of refrigerant pollution, concentrated solution crystallization a lot, as generator add that heat is excessive, the weak solution internal circulating load is too small, vacuum is undesirable, generator take place violent, that condensing pressure reduces, coolant water temperature is spent low, extraneous thermic load is too small etc.Various solutions are being sought to the problem of above-mentioned various generations by each bromine cooling machine factory at present, as with frequency converter canned motor pump being carried out the internal circulating load that VFC is controlled weak solution, control the heat that adds occurred frequently with the steam motor-driven valve.The control of chilled water outlet temperature is regulated the open degree of combustor, steam valve etc.But underload, cooling water inlet temperature are crossed low still do not have better controlled method or device.Usually when bromine cooling machine during in underrun, generating capacity reduces, and the solution amount of flow through heat exchanger and generator reduces, and the heat that the generation cryogen is used in the generator also reduces.The heat that cooling water is taken out of reduces, and cooling water temperature reduces, and weak solution temperature and condenser condenses temperature reduce, and therefore descends in heat exchanger concentrated solution exit temperature, makes concentrated solution be in easier crystalline state.As control mistake is arranged slightly, will cause the concentrated solution crystallization.When cooling water temperature reduced, condensing pressure reduced, and lithium-bromide solution takes place fierce, and strong solution concentration raises, and bromizates the lithium solution droplets and enters condenser with refrigerant vapour, thereby cause refrigerant pollution and concentrated solution crystallization.
The purpose of this utility model provides a kind of lithium bromide refrigerator and prevents underload refrigerant pollution lithium bromide crystallization apparatus, overcomes the shortcoming and defect of prior art.
The purpose of this utility model is achieved in that
A kind of lithium bromide refrigerator prevents underload refrigerant pollution lithium bromide crystallization apparatus, it is characterized by: take over inlet tube at cooling water and connect absorber, absorber connects condenser, condenser connects cooling water and takes over outlet, on condenser connection cooling water adapter export pipeline, be provided with the threeway stepper valve, threeway stepper valve one end is connected cooling water and takes between inlet tube and the absorber, and threeway stepper valve one end connects condenser, and threeway stepper valve one end connects cooling water and takes over outlet.
The normally closed end of threeway stepper valve is connected cooling water and takes between inlet tube and the absorber, and the end that the threeway stepper valve is often opened connects condenser, and the end that the threeway stepper valve is often opened connects cooling water and takes over outlet.
Before absorber, establish temperature controller T1 in the inlet tube pipeline, establish temperature controller T2 in the pipeline between condenser and absorber, in condensator outlet pipe pipeline, establish temperature controller T3, establish temperature controller for three and connect the threeway stepper valve
The utility model has the advantages that:
Advance absorber and go out to increase threeway stepper valve control system between the condenser at cooling water,, guarantee that condensation temperature is identical, constant substantially with normal full load no matter how cooling water temperature and load change.Consequently generator strong solution concentration and condensing pressure are constant, and needn't worry the pollution of concentrated solution crystallization and water as refrigerant.When concentrated solution dilution pipeline can guarantee little load in addition, the concentration reduction of heat exchanger concentrated solution, the solution concentration of heat exchanger outlet is more and more far away from the crystallization line.
Below in conjunction with description of drawings embodiment:
Fig. 1 is that lithium bromide refrigerator prevents underload refrigerant pollution lithium bromide crystallization apparatus structured flowchart
In actual moving process, regular meeting runs into refrigerant pollution at above-mentioned lithium-bromide absorption-type refrigerating machine group, the problem of concentrated solution crystallization.The proposition solution is: adopt the control of threeway pressure head, concentrated solution dilution tube path method.
Threeway pressure head control method: promptly advance absorber and go out to increase threeway stepper valve control system between the condenser,, guarantee that condensation temperature is identical, constant substantially with normal full load no matter how cooling water temperature and load change at cooling water.Consequently generator strong solution concentration and condensing pressure are constant, and needn't worry the pollution of concentrated solution crystallization and water as refrigerant.When concentrated solution dilution pipeline can guarantee little load in addition, the concentration reduction of heat exchanger concentrated solution, the solution concentration of heat exchanger outlet is more and more far away from the crystallization line.As shown in Figure 1, advance absorber and go out to be provided with the threeway stepper valve between the condenser at cooling water, thus control absorber outlet temperature, i.e. condenser inlet temperature.Make condensation temperature and standard state keep the same, the concentration of concentrated solution is the same when also keeping with full load.
