Research On Light Hydrocarbon Gas Ammonia-water Absorption Heat Pump

With the rapid development of China's economy,environmental problems and energy shortages are becoming increasingly apparent.In order to alleviate this problem,the country is committed to reducing the use of coal.The demand for natural gas has gradually increased and there has been a shortage of supplies.Light hydrocarbon as a new type of clean gas is a good alternative energy source of natural gas.It has the characteristics of high calorific value and no pollution.The light hydrocarbon gas is used as the driving heat source to drive the ammonia-water absorption heat pump to cool and heat remote areas or factories.Is a new type of energy use.This article mainly simulates the performance of the light hydrocarbon gas used to drive the ammonia-water absorption heat pump,the effect of the rectifier purity of the system rectifier on the system performance,the influence of the driving heat source temperature on the system performance,and the fuel consumption and mixing The effect of air ratio on system performance is studied and analyzed.Firstly,the current status of light hydrocarbon utilization and the study of gas absorption heat pumps are analyzed.It is concluded that it is theoretically feasible to use light hydrocarbon gas as the driving heat source for ammonia-water absorption heat pumps.Analyze the system composition of the ammonia-water absorption heat pump,model each device of the ammonia-water absorption heat pump,and analyze the factors affecting the performance of the heat pump.Then use Aspen Plus software to simulate the process of mixing air-to-air gas combustion of light hydrocarbon gas,and then to simulate the process of ammonia water absorption cycle.Combine the two process simulations for the entire light hydrocarbon gas ammonia-water absorption heat pump.Process simulation,analyzing the impact of the amount of light hydrocarbon gas feed on the system performance and the effect of the air mixing ratio of the light hydrocarbon gas on the system performance.Finally,suggestions and suggestions are made on the design of the direct-fired generator in the light hydrocarbon gas ammonia-water absorption heat pump,and in order to ensure the supply of the system's heat source and the stability of the supply,the construction and introduction of light hydrocarbon gas stations The appropriate air mixing ratio of system gas supply is studied and analyzed.
