Cross-flow filtration oil-water separation device

Abstract

The invention discloses a cross-flow filtration oil-water separation device. The cross-flow filtration oil-water separation device comprises a filtering channel, wherein a cover body covers the top ofthe filtering channel; an oil collection groove is communicated with the bottom of the filtering channel; a plurality of filtering cartridges which are as high as the filtering channel are arranged in the filtering channel in a staggered manner; the bottoms of the filtering cartridges are communicated with the inner part of the oil collection groove; filtering screens are arranged at positions, which are not provided with the filtering cartridges, between the bottom of the filtering channel and the oil collection groove; the filtering screens have the performance that only oil can pass through the filtering screens, but water cannot pass through the filtering screens. The filtering channel is divided into a wide part, a converging part and a narrow part along a circulation direction of filtering; one end, close to an inlet, of the filtering channel forms the wide part; one end, close to an outlet, of the filtering channel forms the narrow part; the converging part is between the widepart and the narrow part; the oil collection groove and the cover body are molded in a manner of corresponding to shapes of the wide part, the converging part and the narrow part. According to the cross-flow filtration oil-water separation device disclosed by the invention, oil type substances in an oil-water mixture can rapidly enter the oil collection groove under the adsorption effect of a selective filtering material and the gravity effect, and oil-water separation is finished without the need of an external force effect; the cross-flow filtration oil-water separation device has the advantages of large application range, simple structure, high separation efficiency and wide application prospect.

Description

technical field [0001] The invention belongs to the technical fields of mechanical engineering, surface engineering, fluid mechanics and environmental engineering, and in particular relates to a cross-flow filter oil-water separation device. Background technique [0002] The random discharge of oily wastewater will cause oily substances to enter the water body and cause water quality deterioration, air pollution, crop production reduction, and ecological environment deterioration. At present, the treatment of oily wastewater has become an urgent problem to be solved. As an important means to solve oily wastewater, oil-water separation technology has attracted worldwide attention. For example, the process of oil extraction and refining, oil transportation and storage will generate oily wastewater, and oil extraction or oil tanker leakage will aggravate the generation of oily wastewater. Therefore, from environmental protection and other aspects, oil-water separation is of gr...
