摘要/Abstract

摘要： 在Φ1 000 mm的有机玻璃塔中，采用空气-氧-水物系对LPT-2型单喷头式液体分布器的流体力学性能和传质性能进行研究。结果表明：在液体流量1.0~5.0 m3/h、气体流量2 000~10 000 m3/h的条件下，LPT-2型液体分布器的压降为40~120 Pa/m，仅为高效规整干填料压降的15%左右；雾沫夹带分率为0.2%~2.4%，仅为GXD型复式导流浮阀塔板的24%左右；等板高度为0.10~0.25，与泡沫碳化硅波纹、丝网波纹等高效填料相比，在低液体流量下，传质效果接近，在高液体流量下，LPT-2型液体分布器的传质效率提高50%左右。

Abstract: The hydrodynamic and mass transfer performance of LPT-2 type single spray head liquid distributor in the air-O2-H2O system was studied by an organic glass tower (ID1000mm) device. Results show that its pressure drop is between 40-120Pa/m, only 15% of the dry packing pressure drop of the high efficiency packing at liquid flow volume between 1.0-5.0m3/h and gas flow volume between 2000-10000m3/h; Its entrainment percent is between 0.2-2.4%, only 24% of that of the GXD type float valve; The HETP of the LPT-2 is between 0.1-0.25.The mass transfer performance is very close to high efficiency packing at the lower liquid flow volume, but about 50% higher than that of the high efficiency packing at the higher liquid flow volume. LPT-2 type liquid distributor can take the place of the high efficiency packing to work for its better hydrodynamic and mass transfer performance.
