噴霧乾燥機設計를 爲한 重要因子의 特性

Abstract

본 연구는 분무건조기의 설계에 있어서 Atomizer의 조작조건에 따른 여러인자를 연구하였다. Slurry 상으로된 용액을 건조열공기과 접촉시켜서 짧은 시간에 입자로서 건조시키는 것이었다. 건조속도 및 온도분포, 분무기의 분사속도 등을 한정입자로 하여 실험하였다.

This study was carried out to correlate the very important factors and derive an equation for design of spray drying chamber in general form including operating conditions of atomizer.

Taking the largest frop among spray particles as a limiting particle correlate the trajectory equation, drying time of the particle and the parameters which determine the volume of a drying chamber.

Temperature difference between the dry bulb and wet bulb at various local points was measured and compared with over-all temperature difference between inlet and outlet of the chamber.
