Industrial Filtration Solution System for the Future? 一种“堪可改变现状、担保澄清未来”的铸造除尘系统


Since entering the China market, Nederman has been using the German engineer association standard (VDI) as the design basis in the foundry industry, and strictly accord- ing to the article 2066 of the testing, based on the design and provide for the customer in line with the German air quality control technical guidelines (TA Luft dust removal system), and provide a “turnkey” project service. Given the fact that most dust filtration manufacturers in


China were still using the technology of round bag hanging dust collectors from other suppliers, Nederman introduced the flat, modular bag filter (FS) into China, promoted in foundry industry and won good reputation from customers. In parallel, Nederman has focused on educating customers to pay equal attention to also remove and collect the heavy- duty dust. Providing customers with a turn-key solution and thoroughly solving their problems in the workshop process, Nederman has greatly helped improve their working environ- ment. With excellent offline reverse air cleaning technology, not only can customers now have more efficient filtration, lower emissions and a safe work environment, the outside environment and air quality has also improved considerably. Te Tornado hood can capture high temperature fumes at


all stages of melting, pouring and charging of an induction furnace. Hood is controlled and synchronized automatically to adjust to required air volume with high efficiency perfor- mance and less energy consumption. FS Flat bag filter with reverse air cleaning—with the


reverse air fan, not only greatly reduce the energy consump- tion/only 7.5 kW, also using the idea of Europe’s most so- phisticated filtering—steadily retained the dust built-up on the surface of the filter bag to improve filter efficiency. Tis makes the filter operation pressure differential extremely stable, thus greatly extend the service life of the filter bag. Other features of the system include: • Compact structure to reduce space requirements by more than 50%.


• Pre-installation before delivery to ensure the installa- tion accuracy, reduce errors and air leakage, and save onsite installation time.


• Down-flow dirty air chamber design to ensure rapid subsidence and improve the efficiency.


• Convenient detection method for torn bags, to ease maintenance and replacement. 


进入中国市场伊始,尼的曼在铸造领域即以德国工程 师协会标准(VDI)为设计基准,并严格按其第2066条进 行检测,立足为客户设计并提供符合德国空气质量控制 技术准则 (TA-Luft)的除尘系统,并提供“交钥匙”服 务。


鉴于中国除尘领域仍以圆袋悬挂式布袋除尘器为主 的现状,尼的曼公司率先将“扁袋式、模块化袋式除尘 器”(FS型布袋除尘器)介绍到中国,并在铸造除尘系 统中进行推广、应用,赢得了中国客户的广泛赞誉;同 时,尼的曼也针对只重“除”尘不重“收”尘的系统设 计现状,以交钥匙工程模式为客户提供全方位服务,粉 尘捕集、过滤净化并重,彻底解决了车间内工艺线上的 收尘问题,大大改善了工人的现场作业条件,并以优异 的反吹-离线清灰技术提高过滤效率,降低粉尘排放,改 善大气环境质量。


以中频感应电炉除尘系统为例,尼的曼公司提供全 时随动的“龙卷风吸烟罩”捕集熔化、浇注、回铁水、 装料等时段的高温烟气,烟罩动作控制与炉体同步,并 随时自动调节烟气捕集所需风量,在保证收尘效率的同 时节约除尘系统运行能耗。从而将尼的曼公司“尘源捕 集”的理念发挥到极致! • - 自带的反吹风机不仅大大减低了能耗/仅7.5 kW,还最大程度地保持了欧洲最先进的过滤理 念——使粉尘层稳定地留存于滤袋表面提高过滤 效率。使得除尘器运行压差极其稳定,因而大大 延长了滤袋的使用寿命。


• - 结构紧凑、减少占地面积50%以上。 • - 出厂前全预装,以保证加工精度降低漏风系数并 缩短因公差配合错误而带来的现场安装时间。


• - 独特而便捷的防破袋检测技术,快速识别破损滤 袋保证客户有针对的进行维护和更 换,降低劳 动强度和维护成本。 •


- 独特而优异的


滤袋架:双弹簧缠绕结构设 计,确保滤袋和支撑面接触从 而杜绝了“结点”式接触而导 致的滤材磨损;同时弹簧的抖 动慢衰减效应极大地促进了清 灰效果。 
