针对湿帘风机温室试验对通过湿帘后空气温度测量困难的问题,设计屏蔽送风式、屏蔽非送风式和非屏蔽式3种测量方法,通过试验对3种测量方式的准确性及误差因素进行分析。结果表明:屏蔽非送风式的测量结果受湿帘液滴附着影响较小,测量结果准确可靠;屏蔽送风式测量值较真实值小,误差范围为0.1～3.2℃;非屏蔽式测量方式容易受到外界环境因素的影响,误差范围-2.7～3.9℃,波动范围较大。
Aiming at the problem that the temperature of wet air curtain after passing the wet curtain is difficult to test, the three methods of air screening, non-air blasting and unshielded are designed. The accuracy and error of the three kinds of measurement methods Factors for analysis. The results show that the shielding non-blasting results are less affected by the adhesion of the wet curtain and the measurement results are accurate and reliable. The measured value of the shielding blasting is smaller than the real value and the error range is 0.1-3.2 ℃. The unshielded measuring method It is easily affected by external environmental factors. The error range is -2.7 ~ 3.9 ℃ and the fluctuation range is relatively large.
