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.
Shandong Hengyu
Project Overview
- Zaozhuang Hengyu Paper Co., Ltd. is a key specialized and sophisticated enterprise in Shandong focusing on specialty paper and food packaging paper. It holds a leading domestic market share in eco-friendly parchment paper, with products exported to high-end markets in Europe and America. Its production lines adopt various processes including silicon coating, impregnation and base paper making, featuring greatly diversified drying conditions. Extremely strict requirements are imposed on temperature field uniformity, anti-sticking performance, anti-condensation capability and energy consumption control. Tailored to the differentiated operating conditions of Hengyu’s silicon coating lines, impregnation lines and base paper lines, Zhengding Environment developed dedicated Enclosed Hood Systems to achieve consistent and stable operation across multiple lines with remarkable energy-saving results. This further consolidates Zhengding Environment’s reputation and competitive advantages in supplying hood systems for specialty coating, impregnation and base paper production lines.
- All production lines of this project have been put into service. The hood systems on each line run stably with uniform drying and no condensation or dripping. They perfectly meet the high-standard drying requirements for the three differentiated processes of silicon coating, impregnation and base paper production. The overall energy-saving effect is significant, satisfying the enterprise’s demands for high-quality and green production.
Scope of Supply
- Custom Closed Hood Systems for silicon coating production lines are supplied, adapted to the stringent production conditions of silicon coating processes requiring low and uniform temperature, anti-sticking performance and condensation-free operation.
- Custom Closed Hood Systems for impregnation production lines are supplied to meet the process requirements of intensive drying, stable temperature field and defect-free production.
- Custom Closed Hood Systems for base paper production lines are supplied to satisfy the core production demands of stable drying and energy saving for base paper lines.
- Zhengding Environment is responsible for differentiated solution design, complete equipment supply, on-site installation and commissioning as well as full technical services for the hood systems of the three lines, ensuring stable startup and operation of production lines for different processes.
Core technology
- Combined with the northern climatic feature of distinct seasonal temperature differences in Zaozhuang, Shandong, and in response to the demand for year-round stable operation of multi-process lines, the hood sealing and thermal insulation structure are reinforced, and heat utilization logic is optimized to adapt to seasonal temperature fluctuations, balancing reliable equipment operation and energy saving.
- A customized “one line, one solution” design strategy is adopted. Exclusive flow fields, insulation structures and exhaust systems are configured respectively for the differentiated process requirements: low and uniform temperature for silicon coating lines, intensive drying for impregnation lines and stable evaporation for base paper lines. This precisely matches the working conditions of each line to deliver optimal finished paper quality for every paper grade.
- Targeting the tendency of web sticking and defects in coating and impregnation processes, a dedicated anti-condensation and uniform temperature control system is deployed. The enclosed insulation structure and dew point control logic are optimized to precisely regulate the temperature and humidity distribution inside the hood, eliminating local overheating, condensation and dripping, and ensuring smooth sheet surface free of sticking and defects.
- Unified standardized design philosophy is applied for the centralized layout of multiple lines. While satisfying the differentiated process demands of each production line, it facilitates centralized equipment maintenance and management, greatly boosting maintenance efficiency and enabling long-term stable, high-efficiency and energy-saving operation of all lines.
