摘要
超低露点环境营造和控制是目前困扰低湿环境实验研究的难点之一,现有技术在营造干燥环境时,难以实现露点温度的精确控制,尤其是在超低露点环境下的控制调节。因此,提出一种超低露点环境营造策略,采用“置换+净化配气法”实现超低露点环境的控制调节,设计并搭建超低露点环境营造实验台,开展相关实验研究。结果表明:该实验台可完成水蒸气体积分数为10×10~100×10的超低露点环境营造,获得了不同注射量、时间等因素下水蒸气变化增长规律;验证了超低露点环境营造实验台的可靠性和稳定性,实现了不同干燥程度的环境营造。研究成果解决了超低露点环境营造难、难以精确控制的问题,为类似的人工环境营造提供借鉴。
The creation and control of an ultra-low dew point environment is one of the difficulties that currently plague experimental research on low-humidity environments.Existing technologies are difficult to achieve precise control of dew point temperature when creating a dry environment,especially in the control of ultra-low dew point environments.Therefore,this paper proposes a strategy to create an ultra-low dew point environment by using the“replacement+method of distributing purified gas”to regulate the ultra-low dew point environment,and designs and builds an experimental bench to create an ultra-low dew point environment and conducts related experimental research.The results show that the test bench can complete the creation of an ultra-low dew point environment with water vapor content from 10×10—100×10,and obtain the growth law of water vapor change with different injection volume,time,and other factors;this study has verified the reliability and stability of the test bench for creation of the ultra-low dew point environment with different dryness degree.The research has also solved the problem of difficulty to create an ultra-low dew point environment and to control precisely,which provides a reference for creating similar artificial environments.
