分析高速纸机烘缸在工作过程中,水蒸汽放热冷凝后形成水环的运动状态及其对烘缸热量传递过程的影响以及扰动对水环流动状态的影响;在此基础上,详细介绍了烘缸内汽刀式供汽装置的结构设计情况。通过该装置提供所谓的“汽刀”冲击水环,改变层液水环的运动状态,提高传热效率。
Analysis of high-speed paper machine dryer in the course of work, water vapor condensation after the formation of the water ring movement and its impact on the dryer heat transfer process and the disturbance on the water ring flow state; on this basis, the details The structural design of the steam turbine steam supply device in the dryer. The device provides the so-called “steam knife” impact water ring, change the layer of liquid water ring motion, improve heat transfer efficiency.
