在炼油塔中 ,随着增大原油装置的负荷 ,介于最低的产品侧出线和闪蒸段之间的洗涤塔板上液体的流量将下降 ,这会发生冲塔现象 ,从而降低塔板的传质、传热能力。本文建议采用附加筛格堰或转换成填料塔的方式来解决此问题 ,从而提高塔板的操作性能 In the refinery, as the loading of the crude unit increases, the flow of liquid on the wash tray between the lowest product-side outlet and the flash section will decrease, which may lead to knocking which will reduce the Mass transfer, heat transfer capabilities. This paper recommends the use of additional screen grid weir or converted into packed tower way to solve this problem, thereby enhancing the operational performance of the tray
