Abstract

The invention discloses a double-phase rotating stream separation system. Operation and maintenance of the double-phase rotating stream separation system are convenient, and the separation efficiency is higher. The double-phase rotating stream separation system is composed of a motor, a booster pump, a long circulating pipeline, a short circulating pipeline, a rotating stream body and a one-way valve which are connected successively; the rotating stream body is composed of a rotating stream chamber cylinder, a separation cone segment cone body, an external bottom flow segment cylinder, and a bottom flow pipe with reduced diameter steps which are connected successively; the rotating steam body comprises tow overflow ports and two bottom flow ports. Compared with conventional rotating flow separation devices, the double-phase rotating stream separation system can be used for eliminating short-circuit flow, reducing circulation flow, and reducing bottom flow port light phase content greatly; flow field stability of the double-phase rotating stream separation system is increased; high efficiency separation treatment of mixed phases is promoted; the double-phase rotating stream separation system can be used for circulating treatment of the mixed phase containing light phase in short-circuit flow and the bottom flow ports, is small in occupied space, and is simple in operation and management.

Description

technical field [0001] The invention relates to a cyclone separation device used for sewage treatment in the fields of petroleum, chemical industry and environmental protection, in particular to a two-phase separation treatment device, which is applicable to solid-liquid, liquid-liquid and gas-liquid separation. Background technique [0002] At present, for the cyclone separation device, regardless of two-phase separation or multi-phase separation, short-circuit flow and circulation flow near the inlet of the separation device are unavoidable. Due to the existence of short-circuit flow, some heavy phases entering the cyclone are directly discharged from the overflow port without separation, which has a certain impact on the separation effect. The circulating flow has a great influence on the stability of the flow field of the entire cyclone, especially the lower chamber and the large cone section of the cyclone. Previous studies have found that the tangential velocity of th...
