Detailed description of the invention
Below by way of specific instantiation, embodiments of the present invention are described, those skilled in the art the content disclosed by this description can understand other advantages of the present invention and effect easily.The present invention can also be implemented or be applied by detailed description of the invention different in addition, and the every details in this description also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present invention.
Refer to Fig. 1.It should be noted that, the diagram provided in the present embodiment only illustrates basic conception of the present invention in a schematic way, then only the assembly relevant with the present invention is shown in graphic but not component count, shape and size when implementing according to reality is drawn, it is actual when implementing, and the kenel of each assembly, quantity and ratio can be a kind of change arbitrarily, and its assembly layout kenel also may be more complicated.
The invention provides a kind of regenerative apparatus of absorption installation, comprising: solution pump 1, the output of solution pump 1 connects the input of rectifier regenerative apparatus; The output of rectifier regenerative apparatus connects absorber regenerative apparatus input; The output of absorber regenerative apparatus connects the top of absorber regenerative apparatus by generator regenerative apparatus; The top of generator regenerative apparatus connects rectifier regenerative apparatus.
The engineering of this device connects condenser 10 with running water pipe by condenser inlet pipe 8, the ammoniacal liquor that condenser 10 flows out enters subcooler 13, ammoniacal liquor in subcooler 13 belongs to high pressure conditions, the ammoniacal liquor of subcooler 13 enters evaporimeter 16 through reservoir 14, expansion valve 15, evaporimeter 16 gas out enters subcooler 13 again, and the ammonia belonging to low-pressure state now enters absorber 11.
In one embodiment of the invention, rectifier retracting device comprises rectifier 7; Solution pump 1 connects rectifier 7 by solution conduit 2, and rectifier 7 is connected with the top of the absorber coil pipe 12 of absorber regenerative apparatus, the generator 3 of generator regenerative apparatus respectively.The ammoniacal liquor that solution pump 1 pump is come and generator regenerative apparatus ammonia out carry out heat exchange.
In one embodiment of the invention, generator regenerative apparatus comprises generator 3, and the drain pipe 5 of generator 3 connects the absorber 11 of absorber regenerative apparatus, and absorber coil pipe 12 top of absorber regenerative apparatus connects generator 3 by generator liquid back pipe 6.
In one embodiment of the invention, absorber regenerative apparatus comprises absorber 11, and absorber 11 connects cooler 17, enters solution pump 1 and enter rectifier 7 again and circulate after solution and air-conditioning backwater carry out heat exchange in cooler 17.
In one embodiment of the invention, the cooler of cooler 17 goes out pipe 19 and connects user, and the cooler inlet pipe 18 of cooler 17 goes out pipe 9 with condenser 10 condenser and is connected, and condenser inlet pipe 8 connects running water.
In one embodiment of the invention, the heat exchange of absorber adopts countercurrent flow, and the solution of the high heat that generator flows out is from the overhead stream of absorber, and the cryogenic fluid of the coil pipe of absorber bottom to upper reaches, thus carries out heat exchange.
The principle of three place's backheats of unit is as follows:
1, in rectifier, the concentrated solution through subcooler has certain relative low temperature, relative to generator exhaust the low 40-60 ° of temperature.The exhaust of generator due to purity relatively low, bring the moisture of a great deal of to refrigerant circulation into, be unfavorable for the stable of system.So generator high-temperature exhaust air is after entering rectifier, utilize the cold of concentrated solution, the condensate moisture in exhaust is fallen major part, reach more than 99.9% from rectifier refrigerant quality out, meet the purity requirement of machine set system stability completely.And temperature be enhanced after concentrated solution again enter generator and carry out absorbing heat (concentrated solution divide two-way one tunnel to enter generator one tunnel enter absorber inner coil pipe), and evaporate cold-producing medium.Be equivalent to from rectifier, absorb a part of heat, and decrease the input of heat.
2, in generator, coil pipe is set in inside, the opening of coil pipe is arranged on the bottommost of generator.Under the effect of height pressure reduction, to make weak solution spiral from the bottommost of generator rise.Because thermal source is the highest in the bottommost temperature of generator, solution concentration is minimum, and temperature is the highest.Screw in the process risen at solution disk and heat is constantly passed to the relatively low solution of environment temperature, for the evaporation of cold-producing medium, be equivalent to the place not having the combustion heat in higher position, solution still obtains and heats more fully, heat is fully utilized, and can reduce the input of unit heat.
3, in absorber, ammonia is constantly dissolved in weak solution, constantly releases a large amount of heat.But this heat can have influence on the absorption (the lower absorbability of temperature is better) of absorber, even can affect the internal circulating load of cold-producing medium, thus affect the stable of unit.If this part is not used, just cause the waste of heat.By the solution containing a large amount of heat energy, be enclosed in around absorber coil pipe, and the comparatively low temperature concentrated solution being through cooler introduced in absorber coil pipe, heat is constantly exchanged.Cold and hot solution countercurrent flow, efficiency is high.Concentrated solution in coil pipe enters generator and evaporates after absorbing heat.Namely the heat taking back generator belongs to the extra waste heat utilized.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
