Oil-water separation hydrocyclones is the eighties the development of a centrifugal oil-water Its basic principle of the conventional solid-liquid separation hydrocyclone similar to those that use centrifugal force generated by the bound vortex， forcing the oil-water separation in the centrifugal force field， the density of water near the downstream wall continued to rotate， from the lower reaches of export from， and the oil phase to the center of low pressure are part of， and reverse North Korea cyclone outlet upstream movement of the liquid flow in the hydrocyclone with a very short duration， generally about a few seconds， rotating hydraulic oil-water separator Current in multiples of a higher centrifugal The fluid in the hydrocyclone can be accelerated to 3000rpm， the centrifugal force of a multiple of 2000g， it is mainly used in oil field produced water crude oil dehydration and low sewage Oil-water separation hydrocyclones to simple structure， small size， light weight， no moving parts and filter elements， low operating costs， saving energy， separation efficiency， short processing time is being field advantage Oil-water separation hydrocyclones development Liquid - liquid separation of the field of research and development work in England in 1967 from the coast of Hainan "Torreycanyon" tanker died after the incident At that time， a large number of crude oil leaked， resulting in a large area of sea pollution and the death of a large number of In this case the University of Southampton Professor Martin Thew and his colleagues began a liquid - liquid hydrocyclone After several years of efforts， the first liquid - liquid swirl oil remover in 1984 in the experimental success of the marine Commercial sales began in CSPI company in 1989 from BWN VORTOIL PTY LTD swirl VORTOIL purchased technology， and is committed to improving the design of the cyclone， and finally in liquid - liquid hydrocyclone of the applications to gain a leading At present， the hydrocyclone is at home and abroad the most promising solution - one liquid separation equipment， and its research and development work largely concentrated in three areas: First， the importation of non-shear pump of choice and the special non-shear Second， the system Third， the ability to better separation of small droplets of the new cyclone Through research to make oil hydrocyclone used in offshore oil platform， will be liquid - liquid hydrocyclone used in medicine， food， chemical， petrochemical and mining The solid - liquid hydrocyclone used in low-pulp， pharmaceutical， food and chemical In foreign countries， oil-water hydrocyclone separation after more than ten years of technology development and product research， has become a new generation of centrifugal oil-water separator， were successfully used in oil field produced water This separator is simple in structure， small size and performance advantages of multi-purpose， production and application in the field of great In the course of oil field development， the development of almost all water-bearing period of experience， in particular， accompanied by strong water-drive technology of large-scale applications， see the water as early as crude oil， growing faster than the moisture Stable development period， the moisture content of crude oil up to 60 ~ 70%， the development of the latter， the moisture content of crude oil as high as 90% However， water content of crude oil have done great For example， to deal with increased fluid， reducing pipes， the effective utilization of equipment; increase the transmission power consumption process; caused by piping and equipment fouling and corrosion; the impact of oil refining operations， such as For this reason， the development of all countries in the world crude oil strict moisture Such as China's "Oil and Gas Gathering and Transportation Design Code" provides that: passing the water content of crude oil should be not more than 1%; quality of the water content of crude oil should be not more than 5%; foreign requirements ranging from 03 to 0 On the other hand， crude oil removal from oily wastewater， how to handle and use， but also aroused people's Sewage treatment is important the whole world， the oil field wastewater treatment recharge or discharge has become a Ground works in the oil fields， the oil-water separation equipment is one of the indispensable The rapid development of oil and water separation equipment for several decades， from the original write-oil pool， the natural separation of the beginning of the settlement， the development of a wide range of oil-water Electrical devices such as dehydration， free water separator， filler-type of free water separator， air flotation and filtration and so The beginning of the 80's to oil-water separation hydrocyclones represented by centrifugal oil-water separation system in crude oil dehydration and treatment of wastewater However， only in our country from the 90's began to have a better understanding of the technology of individual oil fields have begun to introduce products and put into At present， on the application of hydrocyclones is also limited to the design of the majority of two-phase solid-liquid separation， separation in terms of technological development， or economic interests， as soon as possible in the development of a hydrocyclone liquid - liquid separation equipment like to enhance the removal of sewage Hydrocyclone technology is necessary to understand and
