Refer to Fig. 1.It should be noted that the diagram provided in the present embodiment only illustrates the present invention's in a schematic way
Basic conception, the component relevant with the present invention is only shown in schema then rather than according to component count during actual implement, shape
And size is drawn, kenel, quantity and the ratio of each component can be a kind of random change during its actual implementation, and its assembly layout
Kenel may also be increasingly complex.
The present invention provides a kind of regenerative apparatus of absorption installation, including：Solution pump 1, the output end connection essence of solution pump 1
Evaporate the input of device regenerative apparatus；The output end connection absorber regenerative apparatus input of rectifier regenerative apparatus；Absorber returns
The output end of thermal connects the top of absorber regenerative apparatus by generator regenerative apparatus；The top of generator regenerative apparatus
Connect rectifier regenerative apparatus.
The engineering running water pipe of the device connects condenser 10, the ammoniacal liquor that condenser 10 flows out by condenser inlet pipe 8
Into subcooler 13, the ammoniacal liquor in subcooler 13 belongs to high pressure conditions, and the ammoniacal liquor of subcooler 13 is by reservoir 14, expansion valve 15
Into evaporator 16, the gas that evaporator 16 comes out is again introduced into subcooler 13, and the ammonia for belonging to low-pressure state now enters
Absorber 11.
In one embodiment of the invention, rectifier retracting device includes rectifier 7；Solution pump 1 connects essence by solution conduit 2
Evaporate device 7, rectifier 7 respectively the absorber coil pipe 12 with absorber regenerative apparatus, generator regenerative apparatus generator 3 top
Connection.The ammonia that the ammoniacal liquor and generator regenerative apparatus that the pump of solution pump 1 comes come out carries out heat exchange.
In one embodiment of the invention, generator regenerative apparatus includes generator 3, and the connection of drain pipe 5 of generator 3 absorbs
The absorber 11 of device regenerative apparatus, the top of absorber coil pipe 12 of absorber regenerative apparatus is connected by generator liquid back pipe 6 to be sent out
Raw device 3.
In one embodiment of the invention, absorber regenerative apparatus includes absorber 11, and absorber 11 connects cooler 17, cold
But solution circulates with entering back into rectifier 7 into solution pump 1 after the progress heat exchange of air-conditioning backwater in device 17.
In one embodiment of the invention, the cooler outlet pipe 19 of cooler 17 connects user, and the cooler of cooler 17 enters
Pipe 18 is connected with the condenser outlet pipe 9 of condenser 10, and condenser inlet pipe 8 connects running water.
In one embodiment of the invention, the heat exchange of absorber uses countercurrent flow, the solution of the high heat of generator outflow
Flowed down at the top of absorber, the cryogenic fluid of the coil pipe of absorber bottom is to upstream, so as to be exchanged heat.
The principle of backheat is as follows at the three of unit：
1st, in rectifier, the concentrated solution through subcooler has certain relative low temperature, relative to the exhaust of generator
For temperature it is low 40-60 °.The exhaust of generator brings considerable amount of moisture into because purity is relatively low, to refrigerant circulation, no
Beneficial to the stabilization of system.So generator high-temperature exhaust air enter rectifier after, using the cold of concentrated solution, by the water in exhaust
Divide and condense away major part, the refrigerant quality come out from rectifier reaches more than 99.9%, fully meets machine set system stability
Purity requirement.And the concentrated solution after temperature is enhanced is again introduced into generator and absorbed heat（Concentrated solution divides two-way to enter to occur all the way
Device enters absorber inner coil pipe all the way）, and evaporate refrigerant.Equivalent to absorbing a part of heat from rectifier, and reduce
The input of heat.
2nd, in generator, coil pipe is internally set, the opening of coil pipe is arranged on the bottommost of generator.In height pressure difference
In the presence of make weak solution spiral from the bottommost of generator to rise.Because thermal source is in the bottommost temperature highest of generator,
Solution concentration is minimum, temperature highest.It is relatively low that heat is constantly transmitted to environment temperature during solution disk is screwed on and risen
Solution, for the evaporation of refrigerant, equivalent to not having the place of the combustion heat in higher position, solution has still obtained more sufficient
Heating, heat are fully utilized, it is possible to reduce the input of unit heat.
3rd, in absorber, ammonia is constantly dissolved into weak solution, constantly releases substantial amounts of heat.But this heat influences whether
The absorption of absorber（Temperature more low absorption ability is better）, or even the internal circulating load of refrigerant can be influenceed, so as to influence the steady of unit
It is fixed.If this part is not used, the waste of heat has been resulted in.By the solution containing a large amount of heat energy, absorber disk is enclosed in
Around pipe, and what is introduced in absorber coil pipe is the relatively low temperature concentrated solution through subcooler, heat is constantly exchanged.Cold and hot solution
Countercurrent flow, efficiency high.After concentrated solution in coil pipe absorbs heat, it is evaporated into generator.Take back the heat of generator
Belong to the waste heat additionally utilized.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
Know the personage of this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete without departing from disclosed spirit and institute under technological thought such as
Into all equivalent modifications or change, should by the present invention claim be covered.
