Abstract

The invention relates to a preparation device of a soda ash industrial product, in particular to a carbonation tower and a carbonation system. The invention aims to provide the carbonation tower to overcome the problems that the nucleation speed of a conventional carbonation tower is low, a tower wall is easy to scar and heat exchange is influenced. The carbonation tower of the invention comprisesa tower body, a cooling water jacket wrapped in the middle portion of the tower body, a gas inlet formed in the bottom of the tower body, a gas outlet formed in the top of the tower body, a feeding port formed in the top of the tower body and a discharging port formed in the bottom of the tower body, wherein a stirring structure is vertically arranged on the tower body from top to bottom.

Description

technical field [0001] The invention relates to a preparation device for soda ash industrial products, in particular to a carbonation tower and [0002] carbonation system. Background technique [0003] The carbonation tower is a kind of reaction equipment that utilizes the reaction between carbon dioxide and acidic lye to produce saturated bicarbonate. So far, the most widely used is still the Solvay tower. This tower follows several basic principles of natural crystallization nucleation: [0004] 1. The feed liquid solution contacts with carbon dioxide to form a supersaturated solution; [0005] 2. The supersaturated solution is naturally cooled and crystallized under cooling conditions; [0006] The second point is that in order to allow the crystal nuclei to grow naturally, it is not possible to interfere with the nucleation interface of the supersaturated solution, such as stirring. If the stirring is easy to cause the crystal grains to be too fine, the finished cryst...
