Optimal Device for Waste Heat Recovery Process Based on Convective Drying Technology

Abstract

With the development of chemical industry, medicine, food and other industrial production in China, the amount of drying to wet materials is increasing, and the energy consumption of drying is also increasing year by year. Among them, the hot and humid waste gas produced by convective drying technology contains a large amount of waste heat, and the recovery and utilization of waste heat through the two-stage combination of gas-gas heat exchange and gas-liquid heat exchange is a method to reduce energy consumption, which has good economic value and energy conservation and emission reduction value.
