Jiangxi Liwen Hygiene Paper Manufacturing Co., Ltd.
Project Overview
- Jiangxi Lee & Man Hygiene Paper Manufacturing Co., Ltd. is affiliated with Lee & Man Paper Group, a prominent benchmark enterprise in China’s tissue paper industry. To further improve the workshop production environment, environmental standards and intelligent management level, the company launched a systematic upgrading and renovation project for Paper Dust Removal Systems in the workshop. Covering centralized dust collection for multiple paper machines and rewinding machines, the project imposes high standards on system operational stability, dust removal efficiency, noise control, centralized maintenance, safety and environmental protection indicators.
- Zhengding Environment provided a complete supporting solution of Paper Dust Removal Systems for paper machines and rewinding machines for this project, delivering 12 sets of systems in one go. The whole project was successfully commissioned at a single startup. The systems operate stably with excellent dust removal performance and meet environmental discharge standards, fully satisfying the workshop’s requirements for continuous, efficient and eco-friendly production.
Scope of Supply
- Six dedicated Paper Dust Removal Systems are supplied for 2850 mm paper machines to adapt to dust collection conditions during continuous production of the lines.
- Six dedicated Paper Dust Removal Systems are supplied for 2850 mm rewinding machines, realizing full dust coverage for key equipment across the workshop.
- Zhengding Environment takes charge of overall solution design, supply of complete equipment, on-site installation and commissioning, as well as after-sales maintenance support for the dust removal systems, delivering an integrated centralized dust collection system for multiple machines.
Core technology
- In view of the project’s operating characteristics including densely arranged multiple machines, bulk supporting configuration, continuous heavy-duty production and stringent environmental requirements, an integrated high-efficiency centralized dust removal solution is adopted to meet the unified dust control demands of the large-scale workshop and ensure long-term stable system operation.
- Equipped with dedicated main units for large air volume and high filtration efficiency, the system supports simultaneous dust extraction in the workshop. With sufficient suction power and high filtration precision, it effectively improves the workshop working environment and maintains compliant exhaust emissions.
- The overall pipeline layout and air volume balance distribution are scientifically optimized to solve the air volume equalization issue when the 12 sets of systems run simultaneously. It avoids uneven air pressure and inconsistent dust suction performance, ensuring uniform and stable dust removal effect throughout the whole line.
- Fitted with an intelligent interlocking control system and multiple protection devices, the equipment features low operating noise and controllable energy consumption. It supports centralized monitoring and unified operation & maintenance management, greatly reducing subsequent maintenance difficulty, and fits the standardized, intelligent and green production management system of large paper mills.
