PROCESSED PENTRU INDEPARTAREA PARTICLELOR DINTR-A MEDIU GAZOS

摘要

The invention relates to a process for removing gaseous, solid and/or liquid particles from a gaseous medium, use being made of an auxiliary medium, wherein a first particulate auxiliary medium, 90% (m/m) of which has a size between 50 and 5000 micrometers, is introduced into a first zone of the gaseous medium and into a second zone of the gaseous medium a second auxiliary medium is introduced, of which 90% (m/m) has a size between 0 and 100 micrometers and such properties as to result in interaction between these particles and those of the first auxiliary medium. The process according to the invention is particularly suitable to remove small and very small particles, i. e. having dimensions on the order of magnitude of microns, from gaseous large volume flows, i. e. of 50 000-100 000 m3/h and more, such as occur, for instance, in prilling towers and driers in the chemical industry.
