Four-phase cyclone separator

Abstract

The invention relates to a four-phase cyclone separator, and solves the problem of separation of mediums of integrated four phases of crude oil, water, an associated gas and sediment in a similar produced liquid of an oil field. The four-phase cyclone separator is characterized in that two tangential inlets inclining downwards are symmetrically arranged on the side wall of the cyclone separator; agaseous phase tangential inlet is arranged at the top end of the cyclone separator; an oil phase outlet pipe is inserted into the cyclone separator; the outer surface of an inner cone and the inner wall of the cyclone separator form a gaseous phase separation cavity; a tangential runner is arranged at the lower end of the inner cone, the oil phase separation cavity is arranged between the gaseousphase separation cavity and a water solid separation cavity; a solid collecting chamber is arranged at the lower end of the water solid separation cavity, and an aqueous phase outlet pipe is arrangedon the side wall of the solid collecting chamber. The four-phase cyclone separator has the advantages that the four phases of insoluble mediums of oil, gas, water and solid having density differencesare separated at the same time, the separation efficiency is high, the structure of equipment is compact, and the operation and maintenance costs are low.

Description

technical field [0001] The invention belongs to the field of media separation technology, and in particular relates to a separation technology of four-phase immiscible media with density difference in the fields of petroleum, chemical industry, environmental protection and the like, especially a gas, oil, water and solid four-phase cyclone separator. Background technique [0002] At present, the rapid separation methods applied to multi-phase immiscible media mainly include membrane separation, filtration, air flotation and cyclone separation. The cost of membrane separation equipment is high, and the requirements for medium conditions are relatively strict; the filtration separation method can better realize the separation of multi-phase immiscible media, but frequent backwashing of the filtration equipment is required to ensure the long-term stable operation of the equipment; air flotation The selection method has poor adaptability to the change of dispersed phase concentr...
