Shijiazhuang Tianjinsheng Nonwoven Technology
Project Overview
- Shijiazhuang Tianjin Sheng Nonwoven Technology Co., Ltd. specializes in the R&D and production of filter paper, filter media and new nonwoven materials. It is a key enterprise with professional manufacturing capacity and market influence in China’s filter paper industry. This medium-speed filter paper production project adopts a 2640 mm web width paper machine running at 500 m/min. It imposes stringent requirements on the Enclosed Hood and heat recovery system in terms of temperature & humidity control accuracy, drying uniformity, condensation-free operation and energy-saving performance. Zhengding Environment customizes a complete integrated solution of Enclosed Hood and heat recovery system for this project. Featuring high compatibility with the paper machine and reliable operation, this project further enriches Zhengding Environment’s benchmark references for hood supporting in filter paper and filter media sectors.
- The project has been successfully commissioned and put into operation. The whole system runs stably with uniform drying and excellent heat recovery efficiency. All indicators fully meet the high-precision and high-stability process standards for filter paper, supporting efficient, energy-saving and stable production of the line.
Scope of Supply
- A complete custom Closed Hood System is supplied, adapted to the medium-speed production conditions of specialty filter paper with a web width of 2640 mm and a machine speed of 500 m/min.
- A dedicated heat recovery system is provided to precisely match the evaporation load of filter paper production, effectively boosting waste heat utilization and realizing energy saving for the production line.
Core technology
- Located in Shijiazhuang, Hebei, where seasonal temperature gaps are significant, the project responds to the stringent requirements of filter paper production for stable temperature and humidity, no condensation and no local overheating. The hood insulation and sealing structure together with heat recovery operation strategy are optimized to adapt to seasonal temperature variations in northern China and ensure efficient and stable equipment operation throughout the year.
- Deeply adapted to filter paper processes and medium-speed operating conditions, the evaporation capacity and supply & exhaust air load are calculated precisely based on the web width, machine speed and unique drying characteristics of filter paper. This enables high compatibility among the Closed Hood, heat recovery system and main machine, delivering balanced and stable drying conditions.
- A high-precision closed-loop control system of dew point and temperature dedicated to filter paper is adopted, equipped with accurate temperature & humidity sensors and an intelligent regulation system. It stabilizes internal dew point and supply air temperature, completely eliminating condensation, dripping and local overheating to guarantee consistent sheet quality and reliable performance of finished filter paper.
- The hood sealing and insulation structure is optimized for the large temperature difference between winter and summer in northern regions. It greatly improves sealing performance and waste heat utilization, reduces steam consumption, and achieves the dual objectives of long-term reliable equipment operation and green energy saving.
