不同形式导流板对旋风器性能影响的试验研究

通过对加设不同形式导流板的旋风器进行试验研究,结果表明:不同形式导流板均不同程度地降低了旋风器阻力,同时也对分离效率产生了不同的影响.其中3#、4#导流板降阻幅度较大,但分离效率相对较低;2#的降阻效果强于1#,但弱于3#、4#,同时并没有降低分离效率;1#导流板只在一定限制条件内有减阻效果,其总体分离效率却比较高.

An Experimental Investigation on Pressure Drop and Collection Efficiency of Cyclone Separator with Different Inlet Vanes

Experimental studies have been conducted on pressure drop and collection efficiency of a cyclone separator with different inlet vanes. The results indicate that all the inlet vanes reduce the cyclone pressure drop and also influence the collection efficiency in various degrees. No. 3, No. 4 inlet vanes cause a higher pressure drop reduction, and a lower collection efficiency than without an inlet vane; Of all the inlet vanes, the effect of No. 2 on pressure drop reduction is in the second place and has no reduction in collection efficiency; No. 1 inlet vane has effect on pressure drop within a limited certain conditions but has the highest collection efficiency.
