Design & Fabrication of an Eco-Friendly Filter Drying Machine by Utilizing Waste Heat.

Abstract

The integration of flash steam technology into filter drying processes represents a significant advancement in industrial drying techniques. This paper presents an innovative filter drying machine that leverages flash steam to enhance the efficiency and effectiveness of the drying process. Flash steam, generated by the rapid expansion of high-pressure steam, is utilized to achieve rapid and uniform drying of filter materials. The machine's design incorporates a heating coil in a close chamber where flash steam is circulated, creating a controlled environment (the temperature should be in between 40 to 45˚C) that accelerates the removal of moisture from filters. The benefits of this approach include reduced drying times, lower energy consumption, and improved overall performance compared to conventional drying methods (where the filter were kept in an open place like roof top). Experimental results demonstrate that the use of flash steam leads to higher drying rates and better quality of dried filters. In conventional drying process, approximately 4 to 5 hour is required to dry the wet filter (filter size: 595*595*48) where by using the "Eco-Friendly Filter Drying Machine" now the drying time is only about 30 minute for 595*595*48 size of filter, most importantly in conventional drying process the drying works are depended on weather. This technology not only optimizes operational efficiency but also contributes to energy savings and environmental sustainability. The paper discusses the operational principles, design considerations, and performance metrics of the filter drying machine, providing a comprehensive overview of its potential applications and advantages in various industrial settings.
