Design Improvement on Diesel Particulate Bag Filters 941775

In order to improve the compactness and simplify the structure of diesel particulate bag filter, a preliminary design and test of an envelope bag filter were carried out, and the results confirmed that it is unpractical to adopt envelope bag in diesel particulate bag filter design. Therefore, another double-layer tube bag filter was developed which has a compact and simple structure. The filter was tested on a 485Q diesel engine dynamometer bench, and the results showed that it worked reliably with particulate collection efficiency more than 90% and its effect on diesel economy no more than 1%.
