Abstract
An air washer system with functions of both chemical contaminant removal and heat recovery is developed in this study. The system consists of a heat recovery equipment to recollect heat from scrubber and an air washer to remove undesirable gases such as NH3, SOx, et al. in makeup air unit. The fundamental research and experimental results are reported in this paper, and the principal results are as follows: 1) An optimum L/G (ratio of water to air weight) is obtained, considering the energy saving and gas removal efficiency. 2) The removal efficiency is 90 percent or more for NH3, and 85 percent or more for SOx. 3) The efficiency of heat recovery is about 50 and 30 percent in summer and winter respectively.
