基于CFD的加热仓风量调节装置

摘要

针对目前烟熏生产工艺中普遍存在烟熏效率低下的问题,应用CFD技术对烟熏炉加热仓气流场的流动进行建模与分析.基于仿真结果,提出一种进风口风量调节机构,通过在加热仓的适当位置设置可变流量的进风口,可以改善加热仓的气流场分布;通过对该机构的运动学和动力学仿真,确定了各项参数;并设计实验方案,验证仿真结果的准确性以及调节机构对加热仓气流场的改善效果.应用结果表明该风量调节机构改善了烟熏炉加热仓的气流场分布,使烟熏效果更加均匀.该研究提高了烟熏食品的加工效率.%Aiming at the problem of low smoked efficiency in the smoked production process, this paper applied the CFD technology in the modeling and analysis of smoke fumigator.Based on the simulation results, it proposed a wind quantity regulating mechanism by setting the inlet air with variable flow in the proper position of heating chamber to improve the flow field distribution of the heating chamber.Through the kinematics and dynamics simulation of the mechanism, the parameters of the mechanism were determined.The experimental scheme was designed to verify the accuracy of the simulation results and the improvement effect of regulating mechanism on the flow field of the heating chamber.The application results show that the air flow regulation mechanism improves the distribution of the airflow field in the smoked furnace, makes the smoked effect more uniform and improves the efficiency of food processing.
