Liquid phase distribution control device and partition plate rectifying tower comprising same

Abstract

The invention discloses a liquid phase distribution control device. The device is arranged above a partition plate in a partition plate rectifying tower section; the liquid phase distribution control device sequentially comprises a liquid phase backflow distribution disc, a liquid phase adjusting disc and a liquid phase redistribution disc from top to bottom; the liquid phase adjusting disc comprises a tower disc, a supporting beam, a steering plate, a steering gear, a connecting rod, an end plate, a limiting plate, a gas rising pipe and a liquid phase distributor; the tower disc is provided with the steering plate along the diameter direction, and the steering plate and the partition plate form an up-down structure and form a certain included angle; the steering gear is arranged in the center of the steering plate and connected with the connecting rod; and when the connecting rod rotates, the steering plate is driven by the steering gear to incline by a certain angle in the forward direction or the reverse direction. According to the liquid phase control distribution device, the liquid phase flow on the two sides of the partition plate can be adjusted, the gas-liquid ratio can be flexibly adjusted, and the product purity can be flexibly controlled.

Description

technical field [0001] The invention belongs to the technical field of chemical engineering rectification and separation, and in particular relates to a liquid phase distribution control device and a clapboard rectification tower containing the device. Background technique [0002] Distillation technology is widely used and is the main unit operation to realize the separation of mixtures. However, the rectification process consumes a lot of energy. The energy consumption of the rectification process accounts for more than 20% of the total energy consumption of the entire petrochemical production process. It is a major energy consumer in refineries. . [0003] Generally speaking, when traditional distillation towers are used to separate materials, N-1 distillation towers are required to obtain N products, and the equipment investment and energy consumption required for separation are relatively large. Energy consumption can be reduced to a certain extent by adopting intensif...
