Problems solved by technology
[0002] When the existing flue gas-type lithium bromide absorption chiller uses flue gas for cooling, it is restricted by the temperature of the high-temperature generator, and the heat energy of the flue gas can only be used when the exhaust gas temperature is about 150-160°C, and the low-temperature and low-heat flux density is 150- 160°C flue gas cannot be used by traditional technology, and can only be discharged in vain as waste heat that cannot be used

Embodiment Construction
[0011] see figure 1 , a method for recovering flue gas-type lithium bromide absorption chiller exhaust waste heat of the present invention, a heat medium water heat exchanger is arranged at the flue gas outlet of the high temperature generator, and the flue gas discharged from the high temperature generator passes through the heat medium water heat exchanger , the heat medium water heat exchanger recovers the heat of flue gas with low temperature and low heat flux density that cannot be reused by the high temperature generator, and reduces the temperature of the flue gas to below 100°C. The heat medium water heated by the flue gas is transported into the low temperature generator through the heat source water pump. Heat the low-temperature generator solution to increase the cooling capacity of the flue gas-type lithium bromide absorption chiller.

Disclosed is a method and device for recovering waste heat of exhaust gas of an exhaust-gas-type lithium bromide absorption chiller set. A heating medium water heat-exchanger is arranged on an exhaust gas outlet of a high temperature generator of the exhaust-gas-type lithium bromide absorption chiller set, an exhaust gas passage of the high temperature generator is connected with the exhaust gas outlet of the high temperature generator, and a heating medium water channel output of the heating medium water heat-exchanger is connected with a low temperature generator though pipelines and a heat source water pump. By means of arranging the heat medium water heat-exchanger on the exhaust gas outlet of the high temperature generator, exhaust gas exhausted by the high temperature generator passes through the heat medium water heat-exchanger, heat medium water heated by the exhaust gas is transmitted by the heat source water pump into the low temperature generator to heat solutions in the low temperature generator, so that the cooling capacity of the exhaust-gas-type lithium bromide absorption chiller set is improved, the problem that the existing exhaust-gas-type lithium bromide absorption chiller set cannot utilize the exhaust gas completely, and under the condition of equal amount of exhaust gas, the cooling capacity is increased by 13-15%.
Description
technical field [0001] The invention relates to the technical field of lithium bromide absorption central air-conditioning, in particular to a method and a device for recovering exhaust heat of a flue gas type lithium bromide absorption chiller. Expand the use of flue gas at low temperature and low heat flux density by lithium bromide absorption refrigeration units, increase the utilization of flue gas by flue gas type lithium bromide absorption chillers, and achieve a 13-15% increase in cooling capacity under the same mass flow rate of flue gas. Background technique [0002] When the existing flue gas-type lithium bromide absorption chiller uses flue gas for cooling, it is restricted by the temperature of the high-temperature generator, and the heat energy of the flue gas can only be used when the exhaust gas temperature is about 150-160°C, and the low-temperature and low-heat flux density is 150- The traditional technology of flue gas at 160°C cannot be used, and it can ...
