摘要
为了改善陕西咸阳某纺织厂空压站内温度过高并且分布不均匀、现有通风系统对空压机组不能有效冷却降温的问题,在夏季测试了目前空压站内的温度和风速分布情况,借助CFD数值模拟作为辅助手段,用实测数据对空压站进行模拟,模拟结果与实测数据吻合,说明所建立模型是合适的。在此基础上,利用理论计算得出该空压站送风所需的最大风量,进而确定各个出风口的送风速度;用CFD来分析在最大风量下的温度场及速度场。结果表明:增大送风量、降低送风高度可对空压站有效散热、提升降温效果;同时从节能方面考虑,可采用在过渡季节将室外新风利用风管直接引入空压机吸入口的优化方案。
In order to improve problems of air compressor unit being unable to cool down effectively by the existing ventilation system in an air compressor station of a textile factory in Xianyang,due to high temperature and uneven distribution,the distribution of temperature and wind speed in the air compressor station were tested in summer.The air compressor station was simulated with the measured data by means of CFD numerical simulation.Simulation results were consistent with the measured data,so the model was suitable.On this basis,the maximum air volume of the air supply station was calculated theoretically,and the air supply velocity of each outlet was determined.CFD was used to analyze temperature field and velocity field under the maximum air volume.The results showed that increasing air supply quantity and decreasing air supply height were helpful to increase heat dissipation of air compressor station and improve the cooling effect.At the same time,from the perspective of energy saving,optimization scheme of directly introducing outdoor fresh air into the suction inlet of air compressor by air pipe could be adopted in the transition season.
