The papermaking black liquor spray dryer is mainly used in the liquid molding process and the most widely used process in the drying industry. It is most suitable for the production of powdery and granular solids from suspensions, solutions, emulsions and paste liquids. product. The spray dryer is an ideal drying process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product meet the exact standards during operation.
Key points for the use of paper black liquor spray dryer
1. Contact of hot gas flow with droplets: When there is a sufficient amount of hot gas flow into the spray drying chamber, the direction and angle of the hot gas flow must be considered when operating, whether it is cocurrent, countercurrent or mixed flow, ensuring the droplets Adequate contact is required for adequate heat exchange.
2. Atomization: The atomization system of the spray dryer must ensure that the droplet size is evenly distributed, which is very important.
Because of this, we can ensure the pass rate of product quality.
3. Design of pipe angle and cone angle: We have obtained some empirical data from the production of nearly one thousand spray drying units, which can be shared with you.
The papermaking black liquor spray dryer is the most widely used process in the liquid process forming and drying industry and is most suitable for the production of powdered, granulated or massive solid products from solutions, emulsions, suspensions and plastic paste liquid materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet the exact standards. Spray drying is an ideal process.
