Multi-layer calandria type liquid collecting and distributing device for rectifying tower

The invention relates to a multi-layer calandria type liquid collection and distribution device for a rectifying tower, the device comprises a vertically arranged central collection pipe and a plurality of calandria distribution layers which are sequentially arranged from top to bottom, each calandria distribution layer comprises a plurality of distribution pipes, the inner ends of the distribution pipes are connected with the central collection pipe, the distribution pipes are communicated with the central collection pipe, and the central collection pipe is communicated with the central collection pipe. And distribution holes are formed in the distribution pipe. Compared with the prior art, the device is small in size and height, can save the space in the tower, is high in liquid flow operation flexibility, can be used for precise rectification, especially isotope rectification, and can improve the separation efficiency of the rectification tower and the utilization rate of filler. 本发明涉及一种用于精馏塔的多层排管式液体收集分布装置
