Gas-liquid distribution device applied to filler partition board rectifying tower

Abstract

The invention relates to a gas-liquid distribution device applied to a filler partition board rectifying tower. The gas-liquid distribution device comprises a V-form gas distribution structure, a liquid distribution structure, a convex fixed structure and a base plate, wherein the V-form gas distribution structure comprises V plates and gas distribution caps and is made of a metal steel plate material, and rising gas is uniformly distributed to two sides of a partition board by the gas distribution caps of the V-form gas distribution structure; the liquid distribution structure is formed by uniform liquid descending tanks, and descending liquid flows through liquid descending round holes in the liquid descending tanks and then is distributed to a lower end of the gas-liquid distribution device in a linear manner; the convex fixed structure is just located at the upper end of the partition board to fix the position of the partition board; the base plate is a semi-circular steel plate, square holes and air inlets are uniformly formed in the base plate, and rising gas enters the gas-liquid distribution device through the air inlets in the base plate. According to the gas-liquid distribution device applied to the filler partition board rectifying tower, gas and liquid phases are effectively distributed on two sides of the partition board, the partition board in the center of the filler partition board rectifying tower is effectively fixed, and meanwhile, a wall flow phenomenon in the partition board tower is effectively alleviated; the gas-liquid distribution device is convenient to mount and maintain.

Description

technical field [0001] The invention relates to a gas-liquid distribution device used in a clapboard rectification tower, in particular to a novel gas-liquid distribution device. Background technique [0002] As a new type of thermally coupled rectification column, the clapboard rectification column realizes the separation of multiple components in a single column by installing vertical clapboards in the conventional rectification column, which has the huge advantages of low energy consumption and low cost. Compared with conventional distillation towers, partitioned rectification towers can reduce energy consumption and investment by about 30%, and for some special system separations, energy savings can reach 50%-60%. However, due to the introduction of partitions, the internal structure of the rectification tower has become more complicated, and the requirements for the internal components of the tower are relatively high, especially the gas and liquid distributors on both ...

Problems solved by technology

However, due to the introduction of partitions, the internal structure of the rectification tower has become more complicated, and the requirements for the internal components of the tower are relatively high, especially the gas and liquid distributors on both sides of the partitions in the tower, the rising gas at the bottom of the tower, the tower The distribution uniformity of the top-down liquid through the gas and liquid distributor directly affects the gas and liquid mass transfer efficiency in the tower, and at the same time has an important influence on the product purity and energy consumption in the rectification process.

[0003] At present, the gas and liquid distribution devices widely used in ordinary rectification towers usually cannot meet the needs of clapboard rectification towers in terms of structure. The small two-phase flow area and the uneven distribution of ascending gas and descending liquid hinder the development of high-efficiency gas distributors used in baffle distillation columns, which is also one of the reasons that restrict the wide application of baffle distillation towers.
