Design of a Flexible Centralized Dust Removal System for Cigarette Maker Group

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 kWh/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.
