Improved tubular reactor

Abstract

The improved tubular reactor includes one reactant mixing section, one reactant reacting section and one reaction product outputting nozzle. It features the reactant mixing section with one spiral jetting mixer and the reactant reacting section with one spiral mixer. The material contact order and the spiral jetting mixer in the reactant mixing section are regulated properly to control the mixingdegree, contact area and reaction speed to ensure homogeneous mixing of the materials and moderate reaction speed. The spiral mixer in the reactant reacting section mix the gas phase, the liquid phase and the solid phase gradually for homogeneous, smooth, mild and full reaction to form high quality well atomized slurry.

Description

Technical field:

[0001] The invention belongs to the key equipment in the production process of chemical fertilizers, in particular to a tubular reactor for gas-liquid phase or liquid-liquid phase reaction in the production process of compound fertilizer by chemical synthesis method, especially with gaseous ammonia or liquid A tubular reactor for the reaction of ammonia with acid or mixed acids. Background technique:

[0002] In the compound fertilizer production process, the highest product quality is the chemical synthesis process. The main chemical reaction in the production is the reaction of ammonia and acid or mixed acid, such as phosphoric acid, sulfuric acid, and nitric acid. The currently used ammonification reactors are: There are two kinds of normal pressure and pressurized ammoniation reactors.

[0003] Atmospheric pressure ammoniation reactors mostly use stirring tanks with stirring paddles inside. The fluid flow is a mixed flow, and the reactants can be fully ...
