摘要
基于前人研究得出的高效小型批式粮食干燥工艺,将批式循环粮食干燥机用列管式换热器设计为板式换热器,以更易得到的100℃高温蒸汽代替800℃烟气,将板式换热器采用更为高效的材料,最后在保证换热效率不变的情况下利用matlab优化工具箱优化换热器的尺寸。研究表明:改善之后的换热器具有更高的换热效率,减少了换热器占地面积以及材料的浪费。
Based on the previous research of small batch of grain drying process,exchange the batch type recirculating grain dryer tube for heat exchanger with plate heat exchanger,with easier access to100 DEG C high temperature steam instead of 800 DEG C flue gas,at the same time,plate heat exchanger can also adopt a more efficient material.Finally,using the matlab optimization toolbox for plate heat exchanger model optimization,under the guarantee for thermal efficiency unchanged,the size of the heat exchanger was optimized.Research has shown that after improvement is higher than before the heat exchanger in heat efficiency,and reduces heat exchanger area and the waste materials.
