摘要

为解决工农业干燥过程中存在的干燥效率低、能耗高等问题,同时充分利用生产过程中产生的中低品位热能,设计了一种可控温湿度的中低温热源干燥系统,干燥系统由加热系统、排湿换气系统、温湿度控制系统和干燥室组成。介绍了其干燥工艺,分析了其运行性能和能耗情况,通过试验数据分析发现该干燥系统气流温度和速度分布均匀、能耗低,系统在整个干燥过程中的干燥速率为0.122 kg/(kg∙h),整个过程的能耗因子为391.2 kJ/kg。系统适用于以地热能和工业余热等中低温热能为热源的工农业干燥过程。

Abstract

In order to solve the problems of low drying efficiency and high energy consumption in the process of industrial and agricultural drying and make full use of the medium-low temperature heat source generated in the process of production, a drying system with controllable temperature and humidity was designed. The drying system consists of heating system, dehumidification system, automatic measure & control system and drying shed. The technological process of drying was introduced, and the operation performance and energy consumption were analyzed. Results showed that the temperature and velocity of the air flow were evenly distributed and the energy consumption was low, the drying rate of the whole dryness process was 0.122 kg/(kg∙h), and the total energy consumption factor was 391.2 kJ/kg. This system can use solar energy, geothermal energy and industrial waste heat as drying heat source which is beneficial to reduce energy consumption.
