【摘要】：采用空气-水系统,在直径1 000 mm圆形塔内对3种不同配比的双阀重波纹导向浮阀塔板流体力学性能进行了实验研究。在开孔率15.25%,堰高30 mm,板间距600 mm,3种液流强度下,测定了不同配比的双阀重波纹导向浮阀塔板干板压降、湿板压降、雾沫夹带率和漏液率等流体力学性能参数,并与单阀重波纹导向浮阀塔板进行了相互对比。实验表明:双阀重波纹导向浮阀塔板能够有效地降低雾沫夹带以及漏液,尤其在液流强度较小的时候更加明显,但同时会造成压降升高。其中,配比为26.56%的双阀重波纹导向浮阀塔板在压降增加较小时能够大幅提高雾沫夹带性能,综合性能优越,具有一定工业使用价值。其压降、雾沫夹带率、漏液率的关联公式通过实验数据拟合得出。
[Abstract]:The hydrodynamic properties of three kinds of double valve heavy corrugated guide valve trays were studied in a 1 000 mm circular tower with air water system. Under the conditions of opening rate 15.25 mm, Weir height 30 mm and plate spacing 600 mm / m, the hydrodynamic performance parameters such as dry plate pressure drop, wet plate pressure drop, mist entrainment rate and leakage rate of double valve heavy corrugated guide valve tray were measured. And compared with single valve heavy ripple guide valve tray. The experimental results show that the double valve heavy ripple guide tray can effectively reduce the entrainment and leakage, especially when the liquid flow intensity is small, but it will cause the pressure drop to rise at the same time. Among them, the double valve heavy ripple guide valve tray with 26.56% ratio can greatly improve the entrainment performance of fog foam when the pressure drop is small, and the comprehensive performance is superior and has certain industrial application value. The correlation formulas of pressure drop, entrainment rate and leakage rate are obtained by fitting the experimental data.
