双钩波形板分离器的冷态试验研究

对双钩波形板分离器进行了冷态试验研究,对不同入口速度下波形板的总分离效率、单级分离效率和压降进行了分析,并对不同入口湿度下的总分离效率进行了研究。结果表明:在低速时,提高入口速度有助于提高分离效率,但流速超过临界破膜速度(6m/s)后,二次携带现象明显,导致分离效率降低;增加波形板入口湿度时,总分离效率呈先增后减的趋势;波形板前三级的分离水量显著高于后三级;入口速度对波形板压降的影响较为明显。试验结果对波形板分离器的优化设计具有一定的指导意义。

Cold-state Experimental Study on Corrugated-plate Separator with Double Hook

Cold-state experiment is performed for the corrugated-plate separator with double hook.The total separation efficiency,single-stage separation efficiency and pressure drop of the corrugated-plate under various inlet velocities are analyzed.Then the total separation efficiency under various inlet moistures are studied.The results show that the separation efficiency increases with increasing of inlet velocity when inlet velocity is low,but if inlet velocity is greater than the critical velocity(6m/s),the secondary droplets phenomenon is significant,resulting in decreasing of separation efficiency.The total separation efficiency is first increased and then decreased when the inlet moisture increases.The separation water of the first three stages of corrugated-plate is greater than the last three stages.The pressure drop increases significantly with increasing of inlet velocity.The experiment results provide a certain directive significance for the optimizing design of corrugated-plate separator.
