摘要(Abstract)：
为满足细络联联接的细纱机和络筒机各自所需的温湿度条件,本文采用一种通过调整送风口结构参数来精确控制送风方向及气流分布的定向送风口,利用CFD技术对不同送风口结构下的车间气流分布进行数值模拟,分析对比速度场、温度场及湿度场的分布特点。结果表明:当导流板角度一定时,整流格栅的通孔直径从10 mm增大至32 mm,工作区域的风量和温度分布更均匀,相对湿度可以满足各自工艺需求,但机器周围风速偏高。综合考虑确定通孔直径为30 mm时的送风口结构为最优结构,并试验验证。研究结果可以为纺织空调送风口结构的优化设计提供理论指导。
In order to meet the required temperature and humidity conditions for the spinning frame and the winder in the spinning-winding unit,a directional air supply outlet that precisely controls the air supply direction and air flow distribution by adjusting the structural parameters of the air supply outlet was adopted,the CFD technology was used to numerically simulate the air flow distribution of the workshop under different air supply outlet structure.The distribution characteristics of the velocity field,temperature field and humidity field were analyzed.The research results show that when the angle of the guide plate was constant,the diameter of the through hole of the rectifying grid increased from 10 mm to 32 mm,the air volume and temperature distribution in the working area were more uniform,and the relative humidity met the requirements of the respective processes,but the wind speed around the machine was high.By considering comprehensively,the optimum structure of the air supply outlet was determined when the diameter of the through hole was 30 mm,which was verified by experiments.The research results can provide theoretical guidance for the optimal design of air outlet structure of textile air conditioning.
