A condensate pipe 8 at the outlet of the exchanger and a condensate pipe after the throttling device 7 both are connected into the back throttling device 10. A dilute solution pipe 4 is led from the outlet of a high temperature heat exchanger to enter the working steam condensate generating device exchanger. This device can reduce the load of the condensate heat exchanger, and enhance the thermal efficiency.
Description
The utility model relates to a kind of steam type lithium-bromide absorption-type refrigerating machine and the heat pump working steam coagulates water generating device.Belong to lithium bromide refrigerator attachment technique field.
Working steam coagulated the primary structure of water waste heat recovery and is in the past: the high pressure generator working steam coagulates water through throttling arrangement or behind steam trap, directly enters with fixed attention the water-to-water heat exchanger heat dilute solution and carries out working steam and coagulate the water waste heat recovery.Working steam shwoot after the throttling arrangement step-down produces a large amount of water vapours, and vapour-liquid is mixed into water heat exchanger with fixed attention, influences making full use of of heat exchange area.And the most working steams of steam double-effect unit in parallel coagulate the water waste heat recovery at low pressure generator, and the thermal efficiency is low.
The purpose of this utility model is to provide a kind of can reduce the load of water heat exchanger with fixed attention, reduces the total heat transfer area of heat exchanger, and the steam type lithium-bromide absorption-type refrigerating machine and the heat pump working steam that improve the thermal efficiency coagulate water generating device.
The purpose of this utility model is achieved in that a kind of steam type lithium-bromide absorption-type refrigerating machine and heat pump working steam coagulate water generating device, is in the generator cylindrical shell of unit working steam to be set to coagulate the water generating device interchanger; Flowing to fixed attention at generator, the working steam of water heat exchanger coagulates the throttling arrangement of increase of connecting again after the throttling arrangement in the waterpipe, draw a flash steam pipeline and enter working steam and coagulate the water generating device interchanger from the waterpipe that coagulates between two throttling arrangements, the waterpipe that coagulates that coagulates behind waterpipe and the last throttling arrangement that is coagulated the water generating device exchanger outlet by working steam together inserts a throttling arrangement afterwards; Drawing a weak solution pipeline from high-temperature heat exchanger outlet enters working steam and coagulates the water generating device interchanger.Working steam coagulates flash steam that water produces and enters working steam and coagulate the water generating device interchanger and make thermal source after the throttling arrangement throttling, coagulating that water with fixed attention that flash steam condenses into after the heat release and throttling arrangement come out enters water heat exchanger with fixed attention after water together enters back one throttling arrangement throttling step-down, and working steam coagulates the concentrated direct overflow of solution of water generating device interchanger heating and advances generator.
Above-mentioned working steam coagulates the water generating device interchanger and is placed on above the interior pipe row of high pressure generator cylindrical shell.
Because the utility model is provided with working steam in the generator inner barrel and coagulates the water generating device interchanger, high-temperature heat exchanger outlet weak solution enters working steam and coagulates the water generating device interchanger, after being concentrated by working steam condensed water shoot absorbing Steam Heating outside heat exchanger tube, overflow enters high pressure generator.Working steam coagulates in the water generating device interchanger and to begin to take place after the weak solution temperature rises to uniform temperature, thereby makes the working steam condensed water shoot absorbing steam and the bigger temperature difference of solution maintenance, reduces heat transfer area.Working steam coagulates the load that the water generating device interchanger has reduced to coagulate water heat exchanger, has reduced the total heat transfer area of heat exchanger.To general steam double-effect solution flow process unit in parallel, a part of working steam being coagulated the water waste heat forwards the adding high pressure generator to by original adding low pressure generator, has reduced the consumption of working steam, has improved COP.
Fig. 1 is a general structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail:
As Fig. 1, what this patent proposed is that a kind of steam type lithium-bromide absorption-type refrigerating machine and heat pump working steam coagulate water generating device.Be in high pressure generator 2 cylindrical shells of unit, above the pipe row working steam to be set to coagulate water generating device interchanger 3; Flowing to fixed attention at high pressure generator, the working steam of water heat exchanger 11 coagulates the throttling arrangement 10 of increase of connecting again after the throttling arrangement 7 in the waterpipe 5, draw a flash steam pipeline 6 and enter working steam and coagulate water generating device interchanger 3 from the waterpipe 9 that coagulates between two throttling arrangements 7,10, by working steam coagulate 3 outlets of water generating device interchanger coagulate behind waterpipe 8 and the throttling arrangement 7 coagulate waterpipe 9 together inserts after a throttling arrangement 10; Drawing a weak solution pipeline 4 from high-temperature heat exchanger outlet enters working steam and coagulates water generating device interchanger 3.Weak solution is coagulated the water generating device interchanger from entering working steam after high-temperature heat exchanger comes out, working steam 1 becomes the saturated water that coagulates behind high pressure generator 2, after entering throttling arrangement 7 step-downs, saturation water is because the step-down shwoot, form steam water interface, flash steam enters high pressure generator 2 internal work steam condensation water generating means interchangers 3 tube sides, the heating concentration tube is outer to enter the weak solution that working steam coagulates the water generating device interchanger after high-temperature heat exchanger comes out, flash steam condenses into water simultaneously, together enter throttling arrangement 10 with the water that coagulates after throttling arrangement 7 step-downs, enter water heat exchanger 11 with fixed attention once more after the step-down, the weak solution of water heat exchanger is coagulated in heating, coagulates and leaves unit by coagulating water out 12 after water is further lowered the temperature.High-temperature heat exchanger outlet weak solution 4 enters working steam and coagulates water generating device interchanger 2, heat exchanger tube outside by 6 heating of working steam condensed water shoot absorbing steam concentrated after, overflow enters high pressure generator 2.Working steam coagulates in the water generating device interchanger and to begin to take place after the weak solution temperature rises to uniform temperature, thereby makes the working steam condensed water shoot absorbing steam and the bigger temperature difference of solution maintenance, reduces heat transfer area.
Figure 1 shows that the utility model is used for the scheme of steam double-effect lithium bromide absorption type refrigeration machine.Can also be used in the steam single-action and be the first kind source pump of heating source with steam.Working steam coagulated the water generating device interchanger and was installed in the generator this moment.The solution flow process can be flow process in parallel, serial flow or series and parallel flow process, and cooling water can be flow process in parallel or serial flow.
