膜反转板式降膜吸收过程

Plate falling film absorber with film-inverting configuration

结合板式降膜技术与膜反转技术的优势,提出了一种新型膜反转板式降膜吸收器。设计并建立了膜反转板式降膜吸收试验台,在试验台上完成了不同吸收压力、溶液流量、进口温度、冷却条件等对膜反转板式降膜吸收器传热传质性能影响的系列实验研究,得到该吸收器的传热传质性能。为膜反转板式降膜热质传递设备的科学研究、工程设计和实际应用提供了一定依据,也为进一步开发高效紧凑的热质传递元件及设备提供了一些方法和思路。

Plate falling film absorber with film-inverting configuration is a new type absorber that combines plate falling film absorption with film-inverting technique.An experiment set-up was built and a series of experiments were carried out to study the effects of different conditions,such as absorption pressure,solution flow rate,solution inlet concentration and temperature,and cooling water,etc.,on the absorption process.The performance of the heat and mass transfer for the film-inverting configuration was investigated.Such data can serve as the basis for the design and application of this type of absorber.
