Abstract:

Due to its energy saving, the solid desiccation system has more and more applications. However, the regeneration of the system is beset with high operating cost and complicated equipment. In this study a new electro-osmotic regeneration method was proposed, and the feasibility was explored experimentally. An electro-osmotic regeneration system with a sample box, controlling and measuring apparatus was set up, and its performance was evaluated. In the experiment, an obvious electro-osmotic regeneration effect was observed for the solid to desiccant in the humid air at normal temperature, and the maximum regeneration rate reached 0. 21 g·m^-2·s^-1. It was found that the whole electro-osmosis process was divided into three phases because of the Joule heating effect and electrode corrosion, which hindered the electro-osmotic regeneration. The experiment showed that the Joule heating effect could be reduced by controlling the supplied electric field at the initial stage.
