Taian Yuanwang Energy Investment
Project Overview
- Taian Yuanwang Energy Investment Co., Ltd. is the implementing entity for a key high-end functional paper‑based materials project in Shandong Province, focusing on the R&D and production of advanced functional papers such as electronic‑grade and liquid crystal spacer papers. The project is designated as a provincial and municipal priority initiative and a critical domestic‑substitution effort aimed at overcoming technological bottlenecks. The company has built a 300,000‑ton‑per‑year smart production line for high‑end functional paper substrates, setting exceptionally stringent standards for drying system stability, temperature‑field uniformity, energy efficiency, heat recovery, and long‑term operational reliability. Zhengding Environment has custom‑designed a closed‑cabinet ventilation and heat‑recovery system tailored to the project, precisely meeting the demanding drying process requirements of these advanced functional papers. This solution stands as a flagship case of ZDET’s services for national key new‑material papermaking projects, further strengthening the company’s supporting capabilities and brand influence in the high‑end functional paper sector.
- This project has now been successfully commissioned and put into production. The entire system operates with remarkable stability, delivers uniform drying, boasts excellent heat recovery efficiency, and achieves outstanding energy savings, fully meeting the stringent production standards and energy‑consumption control requirements of high‑end functional paper.
Scope of Supply
- Custom-designed, turnkey enclosed hood systems tailored to the high-precision drying conditions of a 300,000‑ton‑per‑year high‑end functional paperboard production line.
- Equipped with a dedicated ventilation system, it ensures balanced supply and exhaust airflow and stable temperature distribution on the production line, making it well-suited for high-end functional paper manufacturing processes.
- Equip the line with a high-efficiency heat recovery system to maximize waste heat utilization, thereby achieving energy savings, reduced consumption, and green production.
- We assume full responsibility for end-to-end services, including the overall solution design of the supplied products, the delivery of a complete set of equipment, on-site installation and commissioning, and comprehensive technical support throughout the entire process.
Core technology
- In light of Tai’an, Shandong’s pronounced seasonal temperature variations typical of a northern climate, and in response to the stringent requirements of high-end functional paper production—namely uniform temperature distribution, stable dew points, prevention of condensation and dripping, and energy efficiency—we have tailored an insulation and heat-recovery solution specifically adapted to northern conditions. This includes enhanced hood sealing and improved thermal insulation, ensuring stable, reliable operation of the production line throughout its entire lifecycle.
- It is compatible with the production process of 300,000‑ton‑per‑year high‑capacity functional paper, precisely calculating the evaporation load and balancing the air‑handling system. Based on the drying characteristics of large‑capacity paper machines, the amount of evaporated water, and the process curves, it scientifically determines the total supply and exhaust airflow and optimizes airflow distribution, ensuring uniform drying across the entire paper web and seamless integration with the production line.
- To meet the high‑quality production requirements of premium functional papers, a high‑precision dual closed-loop control system—integrating dew point and temperature—is employed, complemented by high‑accuracy sensors and intelligent PID regulation. This ensures stable control of exhaust dew point and supply air temperature, effectively preventing condensation, dripping, and localized overheating, thereby guaranteeing uniform, consistent paper quality and supporting continuous, efficient line operation.
- Optimize the operational logic of the waste heat recovery system to maximize waste heat recovery efficiency, effectively reduce steam consumption on the production line, and simultaneously achieve both long-term equipment stability and green, energy‑efficient production.
