雾化喷嘴夹角对瓦斯水合分离的影响
Effect of Atomization Nozzle Angle on Hydration Separation of Gas
摘要
Abstract
In order to improve the hydration separation effect of high concentration CH4 gas,the separation experiment of high concentration CH4 gas hydrate under the influence of spray nozzle angle was carried out by using the gas rapid hydrating spray experiment device.The influence of nozzle angle on recovery and separation factor of CH4 was discussed by combining gas hydration with the end gas-solid chromatography.The results show that:CH4 gas samples with concentration of 60％ and nozzle angles of 30°,45°,60°,90° corresponding CH4 recovery rates are 20.69％,24.23％,16.83％ and 15.39％,respectively,and the separation factors are 1.69,1.89,1.55,1.49;CH4 gas samples with concentration of 70％ and nozzle angles of 30°,45°,60° 90° corresponding recovery rates of CH4 are 22.44％,25.27％,19.63％ and 17.87％,respectively,the scparation factors are 1.67,1.83,1.52,1.4;CH4 gas samples with concentration of 80％ and nozzle angles of 30°,45°,60° and 90° corresponding recovery rates of CH4 are 22.36％,24.51％,18.81％ and 16.14％,respectively,and the separation factors were 1.90,1.95,1.76,1.75.The three kinds of CH4 gas recovery and separation factors increase first and then decrease with the increase of the nozzles angle,and the influence sequence is 45°＞ 30°＞ 60°＞ 90°.关键词
