为提高仓储除湿系统的工作性能,改善仓储环境中相对湿度的均匀性,设计了管道式转轮除湿系统,并对改造后系统的除湿效果进行了测试和分析。增加了管道式干空气通路,气流组织方式由原来的箱体中部送风、底部回风改为管道开孔送风、底部回风。研究了管道位置、管道直径、管道开孔数对除湿效果的影响。根据不同因素对除湿效果的整体影响效果,综合极差分析和方差分析,得出影响除湿效果因素的排序为管道开孔数、管道直径、管道位置。试验结果表明,最佳除湿效果组合为管道位于箱体中部0.65 m处、管道直径为40 mm、管道开孔数为20个时,除湿能力达71.74 g/(kg?h),除湿效率达0.090 6 g/(kg?h?k J),综合效果好。研究结果对仓储除湿系统的优化设计有一定的参考价值。
In order to improve the working performance of storage dehumidification system and improve the uniformity of relative humidity in storage environment, the dehumidification system of pipeline runner was designed and the dehumidification effect of the system was tested and analyzed. An increase of duct-type dry air path, air flow from the middle of the organization of the original air supply system, the bottom of the air back to the pipe opening air supply, the bottom of the return air. The effects of pipe position, pipe diameter and number of pipe openings on dehumidification were studied. According to the overall effect of different factors on the dehumidification effect, the comprehensive range analysis and variance analysis show that the factors influencing the dehumidification efficiency are the number of pipe openings, pipe diameter and pipe position. The results show that the optimal combination of dehumidification is that the dehumidification capacity reaches 71.74 g / (kg? H) and the dehumidification efficiency reaches 0.090 when the pipe is located at 0.65 m in the middle of the tank, the diameter of the pipe is 40 mm and the number of pipe openings is 20 6 g / (kg? H? K J), the overall effect is good. The research results have certain reference value for the optimal design of warehouse dehumidification system.
