| 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 summarized the current situation and development of ventilation equipment and technology. Intelligence， greenness and high efficiency were 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 were 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 was proposed， dynamically adjusted the supply air volume based on changes in evaporation load， strengthened the monitoring of key parameters and indicators， and improved 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. |
