Integrated gas-liquid-solid continuous separation device

Abstract

An integrated gas-liquid-solid continuous separation device. It includes an upper cover, an outer cylinder and a lower cover. The upper cover, the outer cylinder and the lower cover are connected as a whole through flanges; the inner cavity of the outer cylinder forms three layers of upper, middle and lower layers, and the upper layer is used to store once-separated Oil and gas, the middle layer is used to store the oil after the secondary separation, and the lower layer is used to store the sand and water after the final separation. Each layer is separated by a perforated sieve plate and an oil-absorbing felt; the mixed incoming liquid passes through a tangential The inlet and the helical tube type acceleration flow channel accelerate into the cyclone for primary separation, and then carry out secondary separation through the oleophilic and hydrophobic oil-absorbing felt to realize the continuous separation of multi-phase media. This kind of separation device is based on the joint action of cyclone separation, sedimentation separation and membrane separation to realize multi-stage continuous separation, and can realize high-precision continuous separation of oil-water-sand-gas four-phase medium 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...
