Design of High Efficiency Cyclone for Tiny Cement Industry

Abstract

Air pollution is assuming alarming dimensions from industries, automobiles and house hold fuel burning. Cement industry can be classified as highly air polluting industry emitting PM (Particulate Matter) into the atmosphere. This pollutant is in the form of PM (Particulate Matter) is required to be control by installing air pollution control equipment like ESP (Electrostatic Precipitators), Bag houses, Wet scrubbers and cyclone. Cyclone is considered to be cheaper having low maintenance cost. The present paper aims at designing of high efficiency cyclone by using STAIRMAND METHOD for a tiny cement plant. The efficiency achieved with this design is of the order of 91.1 %. The tiny cement plants are having a capacity of ranging from 20tpd to 50tpd. These cement plant are either based on vertical shaft kiln or rotary kiln technologies. The predominant air pollutant emitted on from such plant is SPM (Suspended Particulate Matter). Control of SPM (Suspended Particulate Matter) can be achieved by installing ESP (Electrostatic Precipitators), Bag houses and Wet scrubbers but these equipments are highly cost intensive and may not be feasible to be installed at such small scale cement plants on techno-economical front. Hence, under the present context, installation of cyclone appears to be a reasonable proposition, which is reasonable cheaper and having low operating cost (16).
