Collaboration Cases
Focusing on the research, development, and application of energy-saving and emission-reduction technologies, with deep expertise in energy efficiency and consumption reduction within the ventilation and drying segments of the paper-making industry.
Fujian Shanying International
Project Overview
- Shanying International, a listed leading enterprise in China’s papermaking industry, mainly produces linerboard, corrugating medium, specialty paper and packaging board, ranking among the top nationwide in total production capacity. The client sets stringent requirements on core indicators including high energy efficiency, reliable operation and waste heat recovery for paper machines. This project involves the upgrading of dryer section systems for high-speed wide-width packaging paper lines at its Fujian base. Zhengding Environment provided professional retrofitting solutions for Enclosed Hoods and heat recovery systems to help the production lines improve efficiency and achieve green, energy-saving upgrades.
- This project focuses on targeted retrofits of the dryer section for the 5800 mm extra-wide, 1500 m/min high-speed linerboard machine, addressing problems of heavy moisture exhaust, excessive energy consumption and insufficient sealing of the original system. After retrofitting, the equipment runs stably with improved drying performance and remarkable energy-saving results, fully meeting the enterprise’s production requirements for high speed, superior quality and low carbon consumption.
Scope of Supply
- Adapted to the high-speed condition with a web width of 5800 mm and machine speed of 1500 m/min, the overall retrofitting of the enclosed hood system for the dryer section of the linerboard machine is completed to optimize hood structure and sealing performance.
- The integrated retrofit of the dryer-section heat recovery system is finished, with heat recovery modules upgraded to improve waste heat utilization of the production line.
Core technology
- Targeting the characteristics of long dryer section, large moisture exhaust and high energy consumption proportion of the dryer section for extra-wide high-speed linerboard production lines, comprehensive optimization and upgrading are carried out focusing on hood sealing, rational airflow organization, waste heat recovery efficiency and on-site adaptability to meet the stringent operating conditions of high-speed wide-width packaging paper production.
- The fully enclosed hood structure of the extra-wide dryer section is upgraded. Tailored to the features of the 5800 mm wide paper machine, the overall hood rigidity and multi-layer sealing structures are optimized to effectively reduce hot air leakage and condensation, stabilize the dryer section environment and improve sheet flatness and overall line efficiency.
- The flow field and dehumidification system dedicated to high-speed operation are optimized. Adapted to the drying characteristics of 1500 m/min high-speed production, the pocket ventilation structure and exhaust air distribution are precisely adjusted to balance drying conditions across the web, lower web break rate and support long-duration continuous stable high-speed production.
- High-efficiency integrated retrofits are implemented for the heat recovery system. Core exhaust heat recovery modules are upgraded and thermal circulation logic optimized to greatly improve heat utilization and cut steam consumption, achieving simultaneous improvements in operational stability and energy conservation.
