(1) High-efficiency particulate air (HEPA) filtration: the HEPA-filtration system used a prefilter screen, a bag filter (Eurovent [EU] 8 rating), and a HEPA filter (EU13 rating). (2) 2×-low-cost filtration: The low-cost-filtration system contained mosquito netting (prefilter), 2 fiberglass furnace filters, and 2 electrostatic furnace filters. (3) Bag filtration: Bag filtration involved the use ...

industrial processes release a range of gaseous and particulate pollutants containing heavy metals into the air. lack of enough attention to the design, installation, repair and maintenance of gas and dust filtration systems in industries, is one of reasons of increasing the emissions of these pollutants. hereon, the steel making processes is one of emission sources of heavy metals. according t...

Emissions of airborne particulate matter are a major cause air pollution. A numerical approach was used to establish single-filter-bag cleaning model based on the discrete phase particle deposition distribution law study effect pulse backflushing operation parameters performance specific structure dust collector. It found that increasing blowing pressure (0.2 MPa 0.6 MPa) and extending width (0...

High dimension of bag-of-words vectors poses a serious challenge from sparse data, overfitting, irrelevant features to document classification. Filter feature selection is one of effective methods for dimensionality reduction by removing irrelevant features from feature set. This paper focuses on two main problems of filter feature selection which are the feature score computation and the imbal...

A polymer based bag filter with high temperature resistance plays a key role in dust and acid gas treatment the power industry.
