Taian Yuanwang Energy Investment
Project Overview
- Tai’an Yuanwang Energy Investment Co., Ltd. serves as the implementing entity for a key high-end functional paper-based material project in Shandong Province, focusing on the R&D and production of high-end functional paper such as electronic-grade paper and liquid crystal spacer paper. This project is a key provincial and municipal research initiative and a critical domestic substitution project to break through bottleneck technologies. The enterprise is constructing a 300,000-ton intelligent production line for high-end functional paper base materials, which sets extremely high standards for the drying system in terms of operational stability, temperature field uniformity, energy saving, heat recovery efficiency and long-term reliability. Zhengding Environment customizes enclosed hood ventilation and heat recovery systems tailored for this project to precisely meet the stringent drying process requirements of high-end functional paper. It stands as a core benchmark case of Zhengding Environment serving national key new-material papermaking projects, further strengthening its supporting capacity and brand influence in the high-end functional paper sector.
- The project has been successfully commissioned and put into production. The complete system runs stably with uniform drying, excellent heat recovery efficiency and remarkable energy-saving performance, fully satisfying the strict production standards and energy control requirements for high-end functional paper.
Scope of Supply
- A complete custom Closed Hood System is supplied, adapted to the high-precision drying conditions of the high-capacity 300,000-ton high-end functional paper base production line.
- A dedicated ventilation system is matched to ensure balanced air supply and exhaust as well as stable temperature field, complying with the production process of high-end functional paper.
- An efficient heat recovery system is configured to maximize waste heat utilization, realizing energy saving and green production for the line.
- Zhengding Environment takes full charge of one-stop services including overall solution design, complete equipment supply, on-site installation and commissioning, as well as full-range technical support for the supplied products.
Core technology
- Taking into account the northern climatic features of distinct seasonal temperature differences in Tai’an, Shandong, and the stringent production requirements for high-end functional paper including uniform temperature field, stable dew point, no condensation or dripping, as well as high energy efficiency, thermal insulation and heat recovery solutions adapted to northern climates are customized. The hood sealing and thermal insulation structure are reinforced to guarantee full-cycle stable operation of the production line.
- Adapted to the production process of the 300,000-ton high-capacity functional paper line, the evaporation load and flow field balance are calculated precisely. Based on the drying characteristics, evaporation capacity and drying curve of the high-capacity paper machine, the total supply and exhaust air volume and air distribution are scientifically computed to achieve uniform drying across the entire web and perfect matching with the production line.
- To meet the high-quality production requirements for high-end functional paper, a high-precision dual closed-loop control system of dew point and temperature is adopted, together with high-precision sensors and PID intelligent regulation technology. It stably controls the exhaust dew point and supply air temperature to eliminate condensation, dripping and local overheating, ensuring consistent finished paper quality and supporting continuous and efficient line operation.
- The operation logic of the waste heat recovery system is optimized to maximize heat recovery rate and effectively cut steam consumption of the production line, balancing the dual goals of long-term stable equipment operation and eco-friendly, energy-saving production.
