| Abstract:Ventilation systems has the greatest potential of optimization in the drying process due to its impact on drying energy consumption, operating costs, and paper quality. This study summarizes the current situation and development of ventilation equipment and technology. Intelligence, greenness and high efficiency are the trends of equipment and technology development. Domestic manufacturers need to strengthen the integration of cutting-edge technologies such as CFD simulation and numerical calculation in equipment development and performance improvement. There are significant differences in energy consumption and operating parameters between different ventilation systems, lack of collaborative controlling between the ventilation system and the steam condensate system, lack monitoring of key parameters and indicators. Conducting an overall analysis and design of the ventilation and steam condensate systems is proposed, dynamically adjust the supply air volume based on changes in evaporation load, strengthen the monitoring of key parameters and indicators, and improve the ventilation control system. Finally, collaborative mechanism of the ventilation system for paper drying should be studied for providing technical and theoretical basis for upgrading ventilation system equipment and technology. |
