Abstract

The invention relates to an airflow spray dryer. The airflow spray dryer comprises a flue gas pipeline, a dryer tower body, a plurality of pneumatic knockers, a main crushing system, a metal expansionjoint, a multi-pipe dust remover and a tail fan which are sequentially arranged, wherein three hot air uniformly-distributing plates which are sequentially arranged along a vertical direction are arranged in the dryer tower body; a plurality of three-fluid spray guns are arranged on the three hot air uniformly-distributing plates in a penetrating mode; each three-fluid spray gun extends downwardsin a vertical direction; the multiple pneumatic knockers are arranged on the side wall of the bottom of the dryer tower body; the main crushing system is installed at the bottom of the dryer tower body; the metal expansion joint is transversely connected to one side of the main crushing system; a discharging opening facing the ground is formed in the bottom of the multi-pipe dust remover; and thetail fan is connected to one side of the top of the multi-pipe dust remover. The spray guns of the airflow spray dryer are simple in structure, and the size of fog drops is convenient to control.

Description

technical field [0001] The invention relates to an airflow spray dryer. Background technique [0002] The airflow spray dryer is a widely used process in the liquid process forming and drying industry. It is suitable for producing powdery and granular solid products from solution, emulsion, suspension and pasty liquid raw materials. Therefore, spray drying is an ideal drying process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet precise standards. However, the nozzle structure of the general airflow spray dryer is relatively complicated, and it is not easy to control the droplet size. Contents of the invention [0003] Based on this, it is necessary to provide an airflow spray dryer with a simple nozzle structure and easy control of the droplet size. [0004] An airflow spray dryer, including a flue gas pipeline, a dryer tower body, several pneumatic knockers, a main crushing system, ...
