Abstract

The invention provides carbonation and crystallization equipment, application thereof and a preparation method for sodium bicarbonate, and relates to the field of chemical equipment. The carbonation and crystallization equipment comprises a crystallization barrel and a carbonization reactor, the carbonization reactor is arranged outside the crystallization barrel and is communicated with the crystallization barrel, and reaction final liquid in the carbonization reactor can enter the crystallization barrel for crystallization treatment. The carbonation nad crystallization equipment has the advantages that the technical problems that an existing carbonation tower is low in production efficiency and large in energy loss due to cleaning can be solved, and the technical effects that the operation efficiency and the production efficiency of the equipment are improved, and the energy consumption is reduced can be achieved.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a carbonation crystallization equipment and its application and a preparation method of sodium bicarbonate. Background technique [0002] with CO 2 Gas or partially containing (eg 40%) CO 2 The gas carbonation of sodium carbonate is an important method to produce food-grade or pharmaceutical-grade sodium bicarbonate, and the carbonation reaction is usually carried out in a carbonation tower. [0003] At present, the carbonation towers mainly used in industry are mushroom cap towers and sieve plate towers. In the towers, the three processes of mass transfer, crystallization and heat transfer are carried out at the same time. The typical carbonation tower is the Solvay carbonation tower, that is, the circle , mushroom cap, bottom bucket and cooling water tank, stacked as the basic form. CO 2 The gas enters from the bottom of the carbonation tower, forms bubbles and flows in a ...
