Elbow Coalescing Three-Phase Cyclone Separator

Abstract

An elbow coalescing three-phase cyclone separator. It is characterized in that: the cyclone separator includes an outer cylinder, an inner cylinder, a coalescing elbow and a diversion port; the outer cylinder includes a gas phase outlet and a large circular platform, and the inner cylinder includes a double tangential inlet, a cyclone section, a cone section, The bottom flow section, the small circular platform, the annular oil phase outlet, the water phase outlet and the spacer; the outer wall of the inner cylinder and the inner wall of the outer cylinder form a gas-liquid separation space; the coalescing elbow adopts a gradual bending diameter, and the diversion port The arc-shaped coalescing elbow is built into the inner cylinder isolator, and the lower side of the isolator has a hole to connect the coalescing elbow inlet. The coalescing elbow inlet, the coalescing elbow and the diversion port are integrated. connect. The elbow coalescing three-phase cyclone has the characteristics of small size, compact structure, stable flow field, high separation efficiency and wide application range, and can effectively solve the three-phase separation equipment faced in production practice in related fields. Problems such as low efficiency, large footprint, and discontinuous processing.

Description

Technical field: [0001] The invention relates to a multiphase medium separation device applied in the fields of petroleum, chemical industry, water treatment and the like. Background technique: [0002] At present, gravity sedimentation method and cyclone separation method are mainly used for three-phase separation. In the gravity settling method, components such as weir plates are usually arranged inside the gravity settling tank, and the structure is relatively complex, and there are also prominent disadvantages such as long separation time and large floor space. The cyclone separator in the cyclone separation method is a device that uses a centrifugal force field for two-phase or multi-phase separation. It has simple structure, large processing capacity and high separation efficiency. The more extensive, but the cyclone separator is mostly suitable for two-phase separation and it is difficult to separate the separation of small particle size. [0003] Northeast Petroleu...

AI Technical Summary

Problems solved by technology

The particle size of the oil droplets in the emulsion is less than 100 μm. Due to the emulsification of the oil droplets, the broken small oil droplets are directly discharged from the bottom outlet of the separator without separation, which has a certain impact on the separation effect, and the high gas content of the oilfield production fluid also causes The efficiency of oil-water separation decreases, which increases the cost of subsequent separation treatment
