四角旋流布置的负压集尘器降尘效果研究
Result research of dust fall under four corners of negative pressure dust collector
摘要
Abstract
In order to raise the efficiency of mining negative pressure dust collector ,improve the environment and safety of the ex-traction face,a four corners-setting of nozzle for the dust collector was put forward ,the parameters of nozzle arrangement was ana-lysed,the efficiency of dust fall and consumption of water which reflect the effect of dust fall was calculated ,the E/E/L model of turbulent flow for gas-liquid-solid of the original and new structure was established and simulated by means of CFD software .The results show that the dust fall efficiency was up to 90% when dust particle size more than 2μm for the new structure and 5%higher than that of the original dust collector ,and which was 1.2 times of the original structure when the dust particle size below 1μm;meanwhile ,new structure was also meet the requirement of water consumption when the dust fall efficiency up to 90%;the droplets full of space ,large range and which relative speed with dust was 1.29 times of the original structure .关键词
