The specific embodiment:
Utility model one as shown in Figure 2, this residual heat type lithium bromide absorption cold water, hot and cold water unit mainly are made up of hot water generator 4, flue gas heat exchange tube bank 6, cylindrical shell 12, liquid distributor 7, flue gas inlet tube 14, smoke outlet tube 15, steam (vapor) outlet 13 and other parts with generator.Hot water generator 4 and flue gas heat exchange tube bank 6 are arranged in the same cylindrical shell 12.Upright waterpipe type structure is adopted in flue gas heat exchange tube bank 6, and promptly flue gas is walked outside the pipe, and solution and the steam that is produced when being heated thereof are walked in the pipe.Hot water generator 4 is the box type structure, its heat exchanger tube 10 is arranged in the casing 9 of opened upper end, walk hot water in the pipe 10, the outer steam that is produced for solution and when being heated of pipe 10, the bottom surface of casing 9 is higher than the liquid level of solution that flue gas heat exchange is restrained 6 tops, and the solution of hot water generator 4 and flue gas heat exchange tube bank 6 then is communicated with liquid distributor 7.The bromize lithium dilute solution that enters hot water generator 4 through solution inlet port 5 is heated generation steam, temperature and concentration raise, go out hot water generator from hot water generator liquid outlet 11 then, when the hot water thermal quantity not sufficient is heated to the pairing saturation temperature of generation pressure with the bromize lithium dilute solution that will enter hot water generator, the solution that goes out hot water generator is that temperature raises, concentration is constant, does not also produce steam in the hot water generator.The solution that goes out hot water generator enters flue gas heat exchange through liquid distributor 7 and restrains 6 bottoms under the gravity effect, further be heated generation steam in flue gas heat exchange tube bank 6, and concentration raises becomes concentrated solution, goes out generator through concentrated solution outlet 8 then.The steam that produces in hot water generator and flue gas heat exchange tube bank all goes out generator from cylindrical shell 12 upper chamber through steam (vapor) outlet 13.Enter the hot water of hot water generator 4 through hot water inlet pipe 3, heat release cooling back goes out generator by hot water outlet pipe 2 in generator, this hot water can be that waste heat hot water is (as the spent hot water who discharges in the technical process such as water-cooled engine jacket water, chemical industry, or the hot water that provides indirectly by hot water heat exchanger by the waste heat thermal source), also can be the hot water that provides by firing equipment, or the hot water that provides jointly by firing equipment and waste heat thermal source.When providing hot water jointly, can adopt mode, also can adopt the mode of passing through hot water heat exchanger indirect heating water by firing equipment and waste heat thermal source by firing equipment and waste heat thermal source direct heating water by firing equipment and waste heat thermal source.Enter flue gas heat exchange tube bank 6 from the waste heat flue gas of external device (ED) (not shown) through flue gas inlet tube 14, the heat release cooling afterwards enters atmosphere by smoke outlet tube 15 through chimney in tube bank.When the smoke evacuation mobilization dynamic of external device (ED) is not enough, air-introduced machine 1 can be set in smoke outlet tube 15.
Utility model two as shown in Figure 3, this residual heat type lithium bromide absorption cold water, hot and cold water unit generator are condenser 16 is set forms at cylindrical shell 12 tops of invention one described generator.When generator is joined the unit refrigerating operaton, walk cooling water in the pipe of condenser heat-exchanging tube bundle; When generator is joined the unit heat supply running, walk hot water in the pipe of condenser heat-exchanging tube bundle.The steam that solution in hot water generator 4 and the flue gas heat exchange tube bank 6 produces when being heated enters condenser, and being cooled at condenser heat-exchanging tube bundle outer surface condenses into water as refrigerant, goes out generator through water as refrigerant outlet 17.
Hot water generator in the generator can adopt immersion structure (as shown in Figures 2 and 3), also can adopt showering spray type structure (as shown in Figure 4 and Figure 5).In the showering spray type hot water generator, solution liquid outlet 7 is arranged on the bottom of hot water generator 4 casings 9, and casing top is provided with liquid distributor 18.
Because the temperature of waste heat flue gas is generally higher (as the exhaust gas temperature of engine at 500-700 ℃, the exhaust gas temperature of miniature combustion engine and gas turbine is at 250-550 ℃), and hot water temperature's (80-130 ℃) generally is lower than the temperature of waste heat flue gas, so the structural configuration that above-mentioned generator adopted can make full use of between concentration difference, hot water and the solution of solution and the temperature difference between flue gas and the solution, to increase heat transfer temperature difference and to reduce heat exchange area, make the generator architecture compactness, the unit miniaturization.Above-mentioned generator is applicable to residual heat type lithium bromide absorption cold (heat) the water unit that utilizes hot water (hot water that comprises waste heat hot water and other form) and waste heat flue gas to drive operation simultaneously; when satisfying air-conditioning cooling (heat supply); reduced the heat exhaust of external device (ED) to environment; energy savings, the protection environment.Wherein, the unit of configuration the utility model two described generators does not need to be provided with condenser, more compact structure again.
