多管束旋流分离器的研制及应用

Development and Application of Multiple Tube Bundle Cyclone Separator

强吸旋流分离器无法根据气量大小控制分离效率,导致气量变化较大时外输露点,出现不合格现象。鉴于此,研制了多管束旋流分离器。该分离器能根据气量大小调节分离管束数量,合理控制气流流速,提高分离效率,且不属于国家强制年检压力容器,减少后续维护工作量。试验结果表明,多管束旋流分离器出口测试水露点均低于系统温度;分离前、后压降小于0.05MPa;在相同工况下,多管束旋流分离器的检测露点均低于原生产分离器,说明该分离器的分离效果优于强吸旋流分离器。

The strong suction cyclone separator cannot control separation efficiency according to gas volume, which leads to outer transportation dew point and disqualification when there is a remarkable variation of gas volume. Therefore, the multiple tube bundle cyclone separator was developed. The separator can regulate the number of separating tube bundles according to gas volume. It can control gas flowrate properly and improve separation efficiency. Moreover, it does not fall within the scope of pressure vessels which are subject to national mandatory annual inspection, thus reducing subsequent maintenance workload. The test findings show that the outlet test water dew point of the separator is lower than the system temperature. The pressure drop is less than 0. 05 MPa before and after separation. In the same operating condition, the inspection dew point of the separator is lower than that of the original production separator, which indicates that this separator is better than the strong suction separator in terms of separating efficiency.
