Cyclone separator treatment efficiency?

2016-06-14View Original

Is the separation efficiency of the cyclone separator related to the amount of liquid droplets in the inlet air, and is that relationship significant? In our project, liquid droplets account for 12% of the inlet flow – does this affect the separation efficiency? Thank you!

A cyclone separator is used for gas-liquid separation, which imposes an upper limit on the amount of liquid carried in the incoming gas. If the liquid content in the incoming air exceeds the upper limit, the cyclone effect will instead disperse again the liquid streams and large droplets present in the air in a semi-separated slug flow state back into the airflow, thereby having a negative impact on separation efficiency. The droplet content at the inlet of your system accounts for 12%, which exceeds the allowed limit; this certainly has a negative impact on the separation process. It is necessary to carry out special treatment on the air flowing into the cyclone separator’s housing through its inlet pipe. Only after the conditions for the air entering the cyclone separator’s internal components are met can the pre-treated air stream, with a lower droplet content, be fed into these components, thereby achieving an optimal separation effect. In recent years, both domestically and internationally, multi-factor cyclone mother-son separators have been adopted to upgrade traditional standard cyclones for efficient gas-liquid separation, especially in gas streams with high liquid droplet loads. The multi-factor swirl parent-child separator belongs to the category of dynamically efficient gas-liquid demisting separators, and its design requires the use of a specialized company in dynamic separation technology, which relies on its proprietary platform for precise dynamic calculations to carry out the design. Otherwise, the actual separation efficiency of cyclone separators designed based on experience differs significantly from the requirements of the process technology, which is a common problem in the operation of cyclone separators in China.
