摘　　要：将热泵干燥技术应用于石膏基墙板的干燥,介绍了影响墙板热泵干燥的相关参数,并设定了干燥室进气温度为70℃、空气流速2m/s、3m/s、4m/s三种不同干燥方案。在此基础上,运用ANSYS热分析模块模拟了三种干燥条件下加热干燥墙板过程中墙板内部不同节点温度随时间变化关系曲线,模拟结果表明:空气温度70℃、流速3m/s在满足了墙板干燥所需热量情况下,尽量缩小了墙板内部各部位的温差,同时也有较高的加热干燥效率,保证墙板干燥的高质、高效。该方案较其他两个方案具有明显优势,可为墙板的热泵干燥装置设计和干燥工艺流程设计提供参考。In the present study,heat pump drying technology was applied to dry gypsum-based wallboard,and the relevant parameters of the wall heat pump drying was introduced,then three different drying programs about the drying chamber’intake air temperature 70℃,and air velocity 2m / s,3m / s,4m / s were set.On this basis,ANSYS thermal analysis module was used to simulate the temperature versus time curve of the different nodes in the wall under the three kinds of conditions of heating and drying dry wall,simulation results showed that：air temperature 70℃ and flow 3m / s can meet the heat required for drying of the wall,narrow the difference in temperature between different parts of the internal wall panels as much as possible,have a higher heating and drying efficiency,and ensure high-quality dry wall panels,efficient heating.This program over the other two programs has an obvious advantage,and provides a basis for heat pump drying equipment design and drying process design.
