The clogging of hydrocyclones as part of the solids control system in the oil industry is a recurrent operational problem. This occurs mainly due to the agglomeration of fine solids in the underflow duct and also to the incidence of higher‐size‐range particles than those specified for the equipment. Another common issue that results in poor performance is the formation of an air‐core in the low‐pressure zone of the separator. In this study, an innovative device coupled to the underflow output of the hydrocyclone was developed in order to minimize these problems. The aim is to mechanically adjust the apex area in a fast and accurate manner, and thus create oscillations in the inlet pressure and flows, constituting a safety system to prevent clogging and air‐core formation.

旨在防止旋液分离器堵塞和空芯形成的机械装置

水力旋流器的堵塞是石油工业中固体控制系统的一部分，这是一个经常发生的操作问题。发生这种情况的主要原因是，下溢管道中的细小固体发生了结块，并且还出现了比设备规定的更大尺寸范围的颗粒。导致性能下降的另一个常见问题是在分离器的低压区域中形成了空芯。在这项研究中，开发了一种与水力旋流器的底流输出相耦合的创新装置，以最大程度地减少这些问题。目的是快速，准确地机械调整顶点区域，从而在入口压力和流量中产生振荡，从而构成一个安全系统，以防止堵塞和空芯形成。
