Nano Fibers in Dust Collection Systems

Cement industry has been developed in productivity and technology as well. In such industry, emission of great amounts of undesirable dust to the atmosphere as associated product takes place. In 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 fabrication of such filters. This type of filters can be used to separate particles with different sizes. In this work, Nano-technology for 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 cement industry is estimated. This force is found to be two times of that found in other collectors, and show higher efficiency by about 70%. The most disadvantage of applying this technology for the time being is the relative high cost of fabrication. Work is in progress to reduce cost of fabrication and hence to use such textiles in dust collectors in cement industry. Finally, the application of nano-technology for preparing dust collectors will lead to better environment by reducing air pollution.
