Description

Oil stain filter

Technical Field

The utility model discloses chemical industry equipment technical field especially relates to an oil stain filter.

Background

The oily wastewater refers to wastewater containing oily substances discharged in the industrial production process. The sources of oily wastewater are very wide. Besides the large amount of oily waste water discharged by the oil exploitation and processing industry, the waste water from the hot processing of solid fuel, the wool washing in the textile industry, the leather-making waste water in the light industry, the emulsion in the turning process in the railway and transportation industry, the slaughtering and food processing industry and the mechanical industry, etc.

The existing forms of the oil in the wastewater can be divided into three types of floating oil, emulsified oil, dissolved oil and the like. The floating oil refers to oil substances which can slowly and automatically float on the water surface to form an oil film or an oil layer after the oily wastewater is kept stand for a period of time. The floating oil is easy to float on the water surface and is the main oil component of the oily wastewater; the oil droplets have larger particle size, generally larger than 100 μm, and are easy to float on the water surface to form an oil film or an oil layer. The emulsified oil is difficult to separate from the wastewater even if the oily wastewater is kept still for a long time, and the particle size of oil droplets of the emulsified oil is small and is generally between 0.1 and 2 mu m. The dissolved oil is oil particles which are dissolved in water in a molecular state, have smaller oil bead diameter than emulsified oil, can be as small as several nanometers in some cases, and are dissolved in water.

If the oily wastewater is not recycled, the waste is caused; if the waste water is directly discharged, the waste water pollutes the water body and influences the survival of aquatic organisms. The oil-water separator is a device for automatically layering water, light oil and heavy oil in a solution by utilizing different specific gravities, and the principle of the oil-water separator is usually static separation, so that the separation effect is poor, the dissolved oil in the oil-water separator is difficult to separate, too much time is consumed, and the separation efficiency is reduced.
