丝网填料是网波纹填料的主要形式,它是由金属丝网制成的。金属丝网波纹填料的压降低,分离效率很高,特别适用于精密精馏及真空精馏装置,为难分离物系、热敏性物系的精馏提供了有效的手段。尽管其造价高,但因其性能优良仍得到了广泛的应用。
利用空气煤油(苯甲酸) 水体系,测定了未装填料和分别装填板波填料、丝网填料、压延孔环填料的鼓泡萃取塔水力学性能和传质性能。
Experimental measurements of hydrodynamics and mass transfer have been carried out with air kerosene (benzoic acid) water system and three typical kinds of packing.
研究结果表明,网纹构型对丝网波纹填料的传质性能有一定的影响。
The results showed there exists certain effect of net structure of corrugated wire gauze Packings on its mass transfer performance.
由此可见,在低液体负荷下,金属丝网波纹填料的表面处理更具有优越性。
Thus it can be seen that the surface treatment of corrugated wire gauze packing has more advantages under a low liquid load.
