AI Technical Summary

Problems solved by technology

However, since the fiber ball filter material has a non-polar lipophilic surface, the oil in the produced water is easily adsorbed on it, making the fiber balls easy to stick into agglomerates and difficult to wash and regenerate, thus limiting the use of the fiber ball filter material in oil fields. Popularization and application in effluent treatment
However, only using ordinary ceramic particles as filter materials has the disadvantages of pore blockage and increased working resistance. Some have low porosity, poor filtering effect, and some are even prone to aging.

Abstract

The invention relates to the technical field of filter mediums for oil-water separation, specifically to a hydrophilic and oleophobic composition. The composition is prepared from the following raw materials by weight: 80 to 90 parts of ceramic particles and 10 to 20 parts of polytetrafluoroethylene, wherein the ceramic particles are prepared from the following raw materials by weight: 50 to 60 parts of silicon dioxide, 20 to 30 parts of aluminum oxide, 5 to 10 parts of spodumene, 10 to 20 parts of calcium carbonate, 0.8 to 1.5 parts of iron oxide, 0.1 to 0.3 part of calcium oxide, 0.4 to 0.8 part of magnesium oxide and 30 to 40 parts of water. The hydrophilic and oleophobic composition provided by the invention has the advantages of strong oil repellency and superstrong hydrophilic property, significant filtering effect, long filtering cycle, strong regeneration property, heat resistance and good heat stability, is suitable for being used as a filter medium applied in a hydrophilic and oleophobic separator.

Description

technical field [0001] The invention relates to the technical field of oil-water separation filter media, in particular to a hydrophilic and oleophobic composition. Background technique [0002] my country's oil fields are widely distributed throughout the northeast, north, south-central, southwest, central China and southeast coastal areas. Since most oilfields in my country have entered the middle and late stages of development, the water content in the produced oil is very high. After the crude oil is collected, a large amount of oily wastewater—produced water will be produced. The water content has reached 70% to 80%, and some oil fields even reach as high as 90%, a large amount of oily sewage is produced after oil-water separation. Oily sewage needs to be treated before being discharged, otherwise it will cause soil and water pollution. Quartz sand and walnut shell are currently two commonly used filter materials in hydrophilic and oleophobic filters, but the non-ideal...
