基于液相调节的除尘器阻力特性

以节流型自激式水幕除尘器为研究对象，通过对节流强度α、总阻力损失h和节流液位差ΔH等的研究，探讨了液相调节作用下除尘器的阻力特性，得出除尘器α值与气体流速v呈线性关系，α-v曲线斜率受除尘器内部设备阻力的影响，阻力系数越大，斜率越小；除尘器h-v曲线是直线和抛物线的组合体，当初始节流强度α0 >0且v较小时，体现出明显的抛物线特性，当α0<0或α0>0且v较大时，h-v曲线体现出直线特性；液相通过自身流动性来改变气液两相的受力平衡，达到调节除尘器阻力的目的。

Resistance characteristics of dust separator based on liquid phase adjustment

Throttle-type self-excitation dust separator was chosen as the study object.Through the study of dust separator’s throttle strength value α，total pressure loss value h and throttle liquid-level difference value ΔH，the dust separator resistance characteristics，based on adjustment of liquid phase，was explored.The primary conclusions are as follows：there is linear relationship between α value and gas velocity value v.And the slope of  α-v curve is affected by the equipment resistance coefficient in dust separator.The slope value reduces with the increase of equipment resistance value.The dust separator h-v curve is made up of straight line and parabola.When the initial throttle strength value α 0 >0 and the gas velocity  v  is on the small side，the h-v curve exhibits a parabolic distribution obviously.Whereas if the initial throttle strength value α 0 <0 or α 0 >0 and the gas velocity v  is on the great side，the h-v curve exhibits a linear distribution.The equilibrium condition of force is changed by the self-fluidity of liquid-phase；as the result，the resistance characteristics of dust separator are adjusted by that.
