Nano Fibers in Dust Collection Systems

Abstract

The cement industry has developed in productivity and technology as well. In such an industry, the emission of great amounts of undesirable dust to the atmosphere as an associated product takes place. In the cement industry dust collectors with different technologies are in use. The most common type is that fabricated from textile polymers. In the last decade, nano-technology was introduced for the fabrication of such filters. This type of filter can be used to separate particles of different sizes. In this work, Nano-technology for the production of textiles used for filters for dust collectors is considered and compared with other types of dust collectors. The tensile force for textiles prepared by the application of nano-technology to be used in the proposed dust collectors in the cement industry is estimated. This force is found to be two times that found in other collectors and shows higher efficiency by about 70%. The most disadvantage of applying this technology, for the time being, is the relatively high cost of fabrication. Work is in progress to reduce the cost of fabrication and hence to use such textiles in dust collectors in the cement industry. Finally, the application of nano-technology for preparing dust collectors will lead to a better environment by reducing air pollution.
