The present invention adopts technique scheme, externally exports unnecessary electric energy, realize recovery and the conversion of energy while refrigeration, improves the comprehensive utilization ratio of the energy, remarkable in economical benefits.
Accompanying drawing explanation
The brief description marked in accompanying drawing content and figure is as follows:
Fig. 1 is structural representation of the present invention;
Be labeled as in figure:
1, electricity generating device, 2, refrigeration plant, 3, generator.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technological scheme.
Structure is as shown in Figure 1 a kind of lithium bromide refrigerating of the present invention and power generation system.Above-mentioned lithium bromide refrigerating and invention system comprise power generation system and lithium bromide refrigerator two-part.Tradition BrLi chiller utilizes high pressure steam as driving heat source, externally only exports cold.
The present invention improves existing lithium bromide absorption chiller system, makes it while refrigeration, externally exports electric energy, solve lithium bromide chiller efficiency of energy utilization not high, cause the problem that steam quality is wasted, improve the comprehensive utilization ratio of the energy.
In order to overcome the defect that prior art exists, realize the goal of the invention improving the utilization ratio of the energy, the technological scheme that the present invention takes is:
As shown in Figure 1, lithium bromide refrigerating of the present invention and power generation system, comprise electricity generating device 1 and lithium bromide refrigerating device 2, and described electricity generating device 1 is provided with steam flooding motivation and generator 3; Steam input pipe is driven to be connected with described steam flooding motivation; The steam (vapor) outlet pipeline of steam flooding motivation is connected with lithium bromide refrigerating device 2.
According to technique scheme, electricity generating device 1 and lithium bromide refrigerating device 2 are connected in series.Drive steam first to enter steam pressure difference electricity generating device 1, generator 3 generates electricity and exports electric energy, and electricity generating device 1 exhaust steam enters lithium bromide refrigerator again, drives lithium bromide refrigerating mechanism cold, exports cold.
Wherein, the steam flooding motivation in electricity generating device 1 is radial steam turbine.Or described steam flooding motivation is screw expander.
Type by following condition determination steam driver:
When described driving steam flow is comparatively large, namely steam flow is more than or equal to 6 tons/hour, and described steam flooding motivation should adopt radial steam turbine; When described driving steam flow is less, namely steam flow is less than 6 tons/hour, and described steam flooding motivation should adopt screw expander.
The flow of steam is driven to equal the design driven steam flow of lithium bromide refrigerating device.
Described lithium bromide refrigerating and power generation system are provided with reject steam pipeline, and described steam input pipe is connected with lithium bromide refrigerating device 2 by reject steam pipeline.
The object of employing reject steam pipeline is: when electricity generating device 1 keeps in repair, can be that lithium bromide refrigerating device 2 supplies steam by reject steam pipeline.Or, during the underfed of the input steam of steam input pipe, then close the pipeline to radial steam turbine air feed, directly to lithium bromide refrigerating device 2 air feed.When working properly, then open the pipeline to radial steam turbine air feed, close reject steam pipeline.
The position of the connection of described steam input pipe and described steam flooding motivation, is provided with steam driven control valve.Described reject steam pipeline is provided with bypass control valve.
In above-described several situation, all controlled by steam driven control valve and bypass control valve.
Application example:
Such as, large sized commercial center needs configuration two BrLi chiller, separate unit refrigerating capacity 7000kW, design separate unit air consumption 7.5t/h.Drive steam to be urban pipe network steam, pressure 0.9MPa, temperature is 188 DEG C.
Adopt lithium bromide refrigerating of the present invention and power generation system, every platform equipment can increase generated energy 145 kilowatts.With use merely compared with BrLi chiller, when refrigerating capacity is constant, every platform equipment 1 hour fecund goes out electric power 145 degree, and steam consumption only increases about 0.4 ton/hour.Remarkable in economical benefits.
