摘要
详细分析了实用新型专利3D窄条阀塔盘的结构特点、实验研究和工业应用情况。在1000 mm×350 mm规格的试验塔中,以空气和水为工质进行了冷模实验,测定了多种气液负荷下3D窄条阀的总板压降、雾沫夹带、泄漏量等流体力学性能,利用氧解吸法标定其塔板传质效率,并在相同条件下与F1浮阀进行了对比试验。试验结果和工业应用表明,3D窄条阀的塔板效率远高于传统的F1浮阀,且峰值范围宽广,压降低,在操作弹性范围内泄漏量趋于0,只是在泄漏点以下其泄漏量比F1浮阀稍高,是一种综合性能优良的新型浮阀。
The structural features, experimental studies and industrial uses of a novel patent-3D narrow strip float valve were presented. In an experimental rectangular column of 1 000 mm× 350 mm, the pressure drop, entrainment, weeping rate were measured by using air-water system, and tray efficiency was determined by the method of oxygen-desorption, and was compared with Fl-type valve under the same condition. Experimental results and industrial uses show that tray efficiency of 3D narrow strip float valve is evidently better than that of Fl-type valve, and has a wider peak range and lower pressure drop; weeping rate tends to zero in operating flexibility range, but is slightly higher than Fl-type valve below weeping point. Consequently, 3D narrow strip float valve is a better new valve in terms of comprehensive performance.
