By reference to the accompanying drawings, embodiments of the invention are provided as follows:
As shown in Figure 1: the waste heat recycle method of the gas electricity generator described in the present embodiment arranges heat exchanger for heat medium water in the outlet of gas electricity generator high-temperature flue gas, described heat exchanger is known heat-pipe heat exchanger, steam line is connected with the generator of lithium-bromide absorption-type refrigerating machine, it is refrigeration agent with water, take lithium-bromide solution as absorbing agent.The high-temperature steam produced by heat exchanger enters in generator, continues to carry out heat exchange to the lithium-bromide solution in it, makes that the water in the lithium-bromide solution in generator constantly gasifies, concentration constantly raises, and forms refrigerant vapor and high concentration lithium bromide.High concentration lithium-bromide solution enters in the adsorber of lithium-bromide absorption-type refrigerating machine, constantly absorbs refrigerant vapour, and the concentration bromizating lithium solution progressively reduces, then sends generator back to by solution pump, completes whole circulation; Refrigerant vapor then enters in lithium-bromide absorption-type refrigerating machine condenser, and and the cooling water carrying out heat exchange by adsorber again carry out heat exchange, cooling water is dispelled the heat by cooling tower, condensation after water vapour cooling, become liquid water, this liquid water is when entering vaporizer, vaporize due to rapid expansion, and a large amount of absorption enters the heat of 12 DEG C of chilled waters in vaporizer in vaporescence, chilled water is cooled to 7 DEG C and is used to user by Cemented filling, thus reaches the object of cooling refrigeration.Between vaporizer 8 and adsorber 12, be connected with refrigerant vapour pipeline, the refrigerant vapour that vaporizer is produced enters in adsorber 12; The cryogenic fluid pump 10 that vaporizer 8 connects makes cryogen circulated sprinkling in vaporizer 8, makes it fully vaporize.
The present invention also can arrange the second heat exchanger 14 between the generator 4 of lithium-bromide absorption-type refrigerating machine and adsorber 12, the low temperature lithium-bromide solution that the high temperature lithium-bromide solution that generator is flowed out and adsorber flow out carries out heat exchange at this second heat exchanger, heating enters the temperature of the lithium-bromide solution in generator, increases work efficiency.
The present invention also can arrange the 3rd heat exchanger 15 between heat exchanger 1 and the generator 4 of lithium-bromide absorption-type refrigerating machine, when not needing refrigeration, close the stop valve 2 between heat exchanger 1 and generator 4, open the stop valve 3 between heat exchanger 1 and the 3rd heat exchanger 15, produce hot water for life 16 by the 3rd heat exchanger 15.
The device that the present invention realizes said method employing forms primarily of heat exchanger 1, lithium-bromide solution generator 4, condenser 5, vaporizer 8, adsorber 12, second heat exchanger 14 and the 3rd heat exchanger 15, gas-steam type heat pipe heat exchanger 1 is arranged on the smoke outlet pipeline of gas electricity generator, and the steam (vapor) outlet end of this gas-steam type heat pipe heat exchanger 1 is all connected with the generator 4 of lithium-bromide absorption-type refrigerating machine with condensed water entrance point.Lithium-bromide absorption-type refrigerating machine is known products.This gas-steam type heat pipe heat exchanger 1 with the connecting tube of generator 4 being provided with stop valve 2, can closing when not needing refrigeration.The high concentration lithium-bromide solution outlet of generator 4 enters adsorber 12 top of lithium-bromide absorption-type refrigerating machine through the second heat exchanger 14, reduction valve 13, and be in shape spray inflow absorber 12, after carrying out heat exchange with the cooling water 6 entered in it, the concentration bromizating lithium solution progressively reduces, send generator 4 by solution pump 11 back to through the second heat exchanger 14 again, realize recycling of lithium-bromide solution.The high-temperature water vapor outlet of generator 4 is communicated with condenser 5 by pipeline.The entrance point being arranged on condenser 5 inner cooling water pipeline is communicated with the coolant outlet pipeline of adsorber 12 by pipeline, and the outlet end supercooling tower that is connected with cooling tower dispels the heat and recycles.Refrigerant vapour is lowered the temperature after condensation in condenser 5, and become cryogen water, enter in vaporizer 8, vaporizer 8 by throttle valve 7, it is connected with chilled water pipeline 9 and water pump 10, chilled water pipeline 9 the other end is connected with user.Water pump 10 makes cryogen water form circulation in vaporizer 8 by pipeline, and the top namely in vaporizer 8 is provided with cryogen spraying tube, lower end is provided with cryogen water outer pipe, forms circulation by water pump 10.Between vaporizer 8 and adsorber 12, be connected with refrigerant vapour pipeline, the refrigerant vapour that vaporizer is produced enters in adsorber 12.3rd heat exchanger 15 is set between this gas-steam type heat pipe heat exchanger 1 and generator 4 of lithium-bromide absorption-type refrigerating machine, and is provided with stop valve 3 on its connecting pipeline, produce hot water for life 16 by the 3rd heat exchanger 15.
The present embodiment in use, the high-temperature flue gas that gas electricity generator produces is by after heat exchanger 1 heat exchange, lithium-bromide solution is constantly heated by generator 4 by the water vapour produced, the water bromizated in lithium solution is constantly vaporized, lithium bromide water solution concentration constantly raises, and forms high-temperature vapor and high concentration lithium-bromide solution.High-temperature vapor enters condenser 5, and the cooling water 6 be condensed in device 5 condenses after lowering the temperature, and becomes the liquid water of high pressure low temperature; When the water in condenser 5 enters vaporizer 8 by throttle valve 7, rapid expansion and vaporizing, and in vaporescence, heat exchange is carried out with chilled water in vaporizer 9, thus reach the object of cooling refrigeration; In the process, high concentration lithium-bromide solution enters adsorber 12, is absorbed by the lithium bromide water solution in adsorber, and solution concentration is progressively reduced, then sends generator 4 back to by recycle pump 11, completes whole circulation.So move in endless cycles, produce cold continuously.Because bromize lithium dilute solution is cooled in adsorber 12, temperature is lower, in order to save the heat of heating bromize lithium dilute solution, improve the thermal efficiency of whole device, add second heat exchanger 14, the low temperature bromize lithium dilute solution that the high concentration lithium-bromide solution that generator 4 is flowed out and adsorber 12 flow out carries out heat exchange, improves the temperature entering lithium-bromide solution in generator 4.When not needing refrigeration, closing the stop valve 2 between heat exchanger 1 and generator 4, opening the stop valve 3 between heat exchanger and the 3rd heat exchanger 15, produce hot water for life 16 by the 3rd heat exchanger 15.
