Integrated gas-liquid-solid continuous separation device

Abstract

The invention discloses an integrated gas-liquid-solid continuous separation device. The device comprises an upper sealing cover, an outer cylinder and a lower sealing cover, and the upper sealing cover, the outer cylinder and the lower sealing cover are connected into a whole through flanges. An upper layer, a middle layer and a lower layer are formed in an inner cavity of the outer cylinder, theupper layer is used for storing oil and gas after primary separation, the middle layer is used for storing oil after secondary separation, the lower layer is used for storing sand and water which arefinally separated, and all the layers are separated through perforated sieve plates and oil absorption felts. Mixed incoming liquid is accelerated to enter a cyclone for primary separation through atangential inlet and a spiral pipe type acceleration flow channel, and then is subjected to secondary separation by oleophylic and hydrophobic oil absorption felts, and continuous separation of a multiphase medium is realized. Multi-stage continuous separation is realized based on the combined action of cyclone separation, settling separation and membrane separation, and high-precision continuousseparation of oil-water-sand-gas four-phase media can be achieved in one device.

Description

technical field [0001] The invention relates to a separation and treatment device for oily sewage used in the fields of petroleum, chemical industry, environmental protection and the like. Background technique [0002] With the continuous development of oilfields and the gradual increase in the water content of oilfield produced fluids, the water content, sand content and gas content of oilfield sewage are also gradually increasing, and the cost of sewage treatment is also increasing. If the oily sewage is directly discharged without treatment, it will not only pollute the soil and water sources, but even destroy the balance of the ecosystem. The more common oily sewage treatment methods mainly include sedimentation separation, cyclone separation and filtration separation. However, these traditional separation methods are not only complicated in process, complex in system, and difficult to transport, but most of the equipment has a single separation medium, which cannot meet...
