Description

An adsorption extrusion oil-water separation device

technical field

The utility model belongs to the field of oily sewage treatment, in particular to an adsorption oil-water separation device.

Background technique

With the development of industrialization, more and more oily sewage is produced, which not only causes serious environmental pollution, but also causes waste of energy resources in short supply. Therefore, the invention of a suitable oil-water separation device to achieve efficient separation of oil and water has important environmental protection and economic significance. At present, the most commonly used oil-water separation devices are mainly gravity sedimentation or centrifugal separation devices, but such devices are difficult to achieve complete separation of oil and water, and are usually used for oil-water separation of sewage with high oil content. The adsorption device is a device that can completely separate oil and water, but after its adsorption is saturated, it usually uses heating to achieve deoiling and regeneration of the filler. Patent CN1286130A discloses an oil-water separation filter irrigation. A heater is placed in the filter irrigation. Heat the saturated filter material to discharge the adsorbed oil to realize its regeneration. Patent CN105903437A discloses a graphene airgel adsorption device that can treat phenol-containing wastewater in petrochemical industry. The device uses hot air to heat saturated graphene to condense The gum is regenerated by expulsion of the adsorbed phenol. Although the above oil-water adsorption and separation devices have a relatively thorough oil-water separation effect, high energy consumption is required for regeneration, which limits their further popularization and application. It is urgent to develop an oil-water adsorption and separation device with low energy consumption.
