面向压缩空气储能的气-水直接接触换热特性
Performances of gas-water direct contact heat exchange for compressed air energy storage
摘要
Abstract
Advanced adiabatic compressed air energy storage(AA-CAES)is a promising technology for solving the problem of renewable energy power consumption.To improve the efficiency of AA-CAES,it is proposed to use direct contact heat exchangers as reheater to make full use of system compression heat.In this paper,the pressurized humidifier experimental system and air-water system is used to study the direct contact heat transfer process.An experimental setup with the foam ceramic corrugated packing was tested under pressurized conditions.The liquid flooding characteristics of the packing were analyzed.The effects of the operating pressure,the water-gas ratio,the inlet water temperature and the inlet air specific enthalpy on the volume mass transfer coefficient and the effectiveness were investigated.The results show that the volume mass transfer coefficient of the packing increases with the increasing water-gas ratio and decreases with the increasing inlet water temperature,while the efficiency decreases with the increase of the water-gas ratio and increases with the increase of the inlet water temperature.The influence of the inlet air specific enthalpy on the direct contact heat transfer process is relatively small.For AA-CAES,when designing direct contact heat exchange processes,the water-gas ratio is proposed to be taken as 1.0-1.2,and the operating pressure is proposed to be taken as 0.3-0.4 MPa.关键词
