摘要: 由于普通旋风分离器不能满足工业中大直径、大流量的分离工艺要求,本文研究表明了气固两相流有效的螺旋运动是旋风分离的关键,加设螺旋导流装置,强制流体进行螺旋运动,可以大幅度提高旋风分离效率;同时顺应气流翻转流动之势,设立防返混结构,能够确保最终分离效果。采用双分离器并联,上接分气罐、下接集尘罐,并使用专利下灰阀,形成完整的分离系统,工业应用效果良好。

Abstract: Common cyclone separating devices cannot meet the technical requirements of large flow rate and high flow velocity. This study shows that the effective spiral movement of dual-phrase distribution of gas-solid is the key for cyclone separation, and cyclone separating devices with spiral guiding devices can make fluids move spirally, which can greatly improve the efficiency of cyclone separation. At the same time, setting up back-mixing preventing structure can ensure the effect of final separation. A complete separation system, which consists of dual-separator in parallel, an atmolysis tank, a dust tank and an ash valve, meets technical requirements in industrial units.

Key words: cyclone separating device, spiral guiding, preventing back-mixing, separating efficiency, industrial application
