摘要
为解决卷接机组开机台数较少情况下,集中风力除尘系统过度冗余而造成能源浪费等问题,利用模块化、柔性化设计理念和管道切换技术,以12台PROTOS 70卷接机组为例,对卷接机组布局以及除尘系统的运行数量等进行了研究与改进:13套除尘系统(FC/FS)中的2套由连接4台卷接机组改为连接6台;2第3套除尘系统连接的4台卷接机组设计为双系统除尘管道,2台与第1套除尘系统连接,另2台与第2套除尘系统连接;3在各双系统除尘管道上配置切换执行单元,增加系统切换功能。结果表明:1在卷接机组不多于5台情况下只需运行1套FC/FS,在不多于10台情况下只需运行2套FC/FS;2在满足卷接机组运行前提下可减少1套FC/FS,节约电量2 640 k Wh/d,节约电费1 663.2元/d。该设计方案的应用,实现了卷接机组与除尘系统联机的快速切换与优化组合,减少了除尘系统的运行数量,有效提高了集中风力除尘系统风能的利用率,较好地解决了能源浪费严重等问题。
To save the energy consumption of a centralized dust removal system when fewer cigarette makers are running,taking a system for a group of twelve PROTOS 70 cigarette makers with three dust removal units as an example,the layout of cigarette makers and the number of running dust removal units were rearranged on the basis of modular and flexible design concept and pipeline switching technology：1）The number of cigarette makers connected to the first and second dust removal units increased from four to six.2） Two of the four cigarette makers connected to the third dust removal unit were connected to the first dust removal unit and the other two to the second dust removal unit separately served as bypasses 3）Adding a switching execution unit in each bypass to direct dust air to desired dust removal unit.The results showed that：1） In the case of less than five cigarette makers in running,only one dust removal unit was needed; if no more than ten,then just two units were needed.2） Under the prerequisite of ensuring cigarette makers＇ running,new system dispensed with one dust removal unit,electric power consumption reduced by 2 640 k Wh/day（1 663.2 RMB Yuan/day）.The quick switching and optimized combination between cigarette makers and dust removal systems promoted the energy efficiency of the centralized dust removal system.
