Paper pulp is a lumpy substance formed by soaking, removing impurities, breaking, pulping, filtering and dehydrating recycled waste cartons, book paper, newspapers, etc. When the moisture content of pulp is reduced, it can be used to make a variety of products, including paper products, textiles, diapers and hygiene products. Since the pulp has a high moisture content and is composed of a variety of fibers, if the drying temperature is too high, it will easily lead to fiber plasticization and even fire; conversely, if the drying temperature is too low, the drying requirements will not be met. Therefore, drying pulp is very difficult, and temperature control is particularly important.
The "three-cylinder multi-return" pulp dryer produced by Zhengzhou Jiutian is based on the single-cylinder dryer through innovative design and transformation. This equipment uses "three-stage multi-loop drying technology" to divide the entire drying process into three stages. Then, according to the characteristics and needs of the pulp, the air volume, wind speed, wind direction and heat are freely distributed and independently regulated; the water vapor is separately The end of each stage is discharged in time, which greatly improves the drying efficiency. At the same time, the moisture content of dry materials can be determined according to the range required by the customer.
Features and advantages:
1. The equipment adopts a three-cylinder structure, which greatly reduces the equipment’s footprint.
2. Automatic operation, high degree of intelligence, low labor intensity, simple and convenient operation.
3. The process technology is mature, the performance is stable and reliable, it can operate continuously for 24 hours, and the equipment failure rate is low.
4. The equipment has a large processing capacity and high heat energy utilization rate, which can save energy, reduce consumption and save production costs.
5. The equipment is tightly sealed as a whole and operates under negative pressure. There are no flammable or explosive phenomena during the production process.
6. The equipment adopts "low temperature and large air volume" drying process, which can not only improve the drying efficiency of the equipment, but also save energy consumption, and at the same time ensure the quality of the finished pulp materials after drying.
Materials:It is suitable for drying all kinds of pulp and can be used in the papermaking industry and the waste paper recycling industry.
Application:Drying paper pulp to achieve required moisture for paper manufacturing.
Wet pulp is fed into the drying system by a screw conveyor or pump. Inside the rotary dryer, the material is continuously lifted and dispersed, allowing full contact with hot air or heated surfaces. Through efficient heat exchange, moisture rapidly evaporates and is carried away by the exhaust airflow.
As drying progresses, the pulp moves gradually toward the discharge end. Final moisture content is typically reduced to the required level for storage or further processing. Exhaust gas is treated by a dust collection system to ensure clean and environmentally compliant operation.
