在筛板塔的基础上，研发了一种新型板式塔——分散降液筛板塔，将传统筛板塔的弓形降液管改为均布于塔板筛孔间的多降液管结构，使整个塔板面成为均匀降液和受液的传质区，并新增淋降和喷溅传质区，在全塔空间内实现立体、连续的微分接触式气液传质过程，另外，塔板之间可以加装填料来强化传质，或装填催化剂以促进伴随化学反应的传质过程。以“氧气-空气-水”为体系，初步研究了分散降液筛板的传质性能及其影响因素，并与传统筛板进行比较，结果表明：分散降液筛板气液分布均匀，接触充分，在同等条件下传质效率比传统筛板提高了8.4%～9.7%。

The decentralized down-comer sieve plate column, a novel plate column, was designed and invented on the basis of the sieve plate column. The segmental down-comer of the traditional sieve plate column was changed into multiple down-comers that evenly distributed among the sieve pores. The new structure made the entire plate into mass transfer zone (MTZ) for well-distributed liquid drop and receiving, and it produced a new shower and splashing mass transfer area. Thus, it realized three-dimensional, continuously differential contact and mass transfer process for gas and liquid. In addition, packing or catalysts can be installed between the adjacent plates to strength mass transfer and promote chemical reactions in the tower. Adopting oxygen-air-water system, the mass transfer characteristics and influencing factors of the efficiency of the new plate were explored and compared with the traditional plate. The results showed that the gas and liquid in the new sieve column were distributed evenly and contacted adequately, and the mass transfer efficiency was higher than that of the traditional sieve plate by 8.4%—9.7% in the same conditions.
