介绍了一种用于腐蚀性乏气余热回收的新型无管束磨损的间热式换热器——双室流化换热器．类比壳管式换热器传热分析，对其传热特性进行了理论研究．研究表明，换热器总热阻由两流化床气固换热热阻和颗粒循环流动传热热阻串联而成；颗粒流量在一定范围内可控制其传热过程；加大气流速度，增加床层横截面积，选用大颗粒及加大颗粒流量等均可强化其传热．为后期研究其传热特性及工业应用提供了理论依据．
A new tubeless intercooled heat exchanger, dual chamber fluidized heat exchanger, is introduced for the recovery of corrosive gas-lean waste heat. The heat transfer analysis of the shell-and-tube heat exchanger is studied, and the heat transfer characteristics are studied theoretically. The results show that the total heat resistance of the heat exchanger is composed of a series of gas-liquid heat resistances of two fluidized beds and a heat transfer resistance of the particles circulating in series. The particle flow rate can control the heat transfer process within a certain range; Increase the bed cross-sectional area, the choice of large particles and increase the flow of particles, etc. can enhance its heat transfer. It provides a theoretical basis for the later study of its heat transfer characteristics and industrial application.
