Problems solved by technology

[0003] Existing industrial distillation towers mainly include tower body and multi-layer trays. It can only detect the reaction temperature of certain trays, but cannot detect the real-time temperature of each layer of trays at the same time. There is an obstacle in the reaction process, which belongs to the "black box"

Abstract

The invention discloses a tower section of a packed tower for chemical synthesis and rectification. The tower section comprises a tower body, wherein the top end of the tower body is provided with a steam escape port and a steam rising port; a rising steam distributor for uniformly distributing rising steam is arranged in the tower body; the upper part of one side of the tower body is provided with an overflow inlet pipe; the lower part of the overflow inlet pipe is a U-shaped liquid end socket positioned in the tower body; and the lower part of the other side of the tower body is provided with an overflow outlet pipe. The tower section can truly simulate energy and mass transferring processes performed between a continuous reactor and a tower plate of a rectification tower, realizes simulation and knowledge of a sub-section (plate) in a chemical reaction or rectification process in a tower apparatus and obtains more suitable and more effective simulation results than a chromatographic column or a spiniform distillation column when applied to the design and amplification of an industrial device.

Description

Technical field [0001] The invention relates to a packing tower section for chemical synthesis and rectification, belonging to the field of chemical reaction engineering and separation engineering. Background technique [0002] In the modern chemical industry, the reaction and rectification unit process pays more and more attention to continuous operation, which not only helps to improve and stabilize product quality, but also plays an important role in simplifying operation and reducing material and energy consumption. At present, in the laboratory, chromatography columns or thorn-shaped distillation columns are usually used to simulate the process of packed towers. However, such simulations themselves have great limitations and errors, such as the distribution of vapor-liquid two-phase fluid channels, The knowledge of the temperature between the towers is extremely limited and still belongs to the "black box". Therefore, for the industrial amplification of this kind of process...
