Abstract

The invention relates to the technical field of petroleum wastewater, in particular to a deoiling and filtering device for petroleum wastewater. The deoiling and filtering device comprises a box body, wherein a first through hole is formed in the top end of a box cover; first clamping grooves are evenly formed in the positions, located on the outer side of the first through hole, of the top end of the box cover; first clamping blocks are clamped in the first clamping grooves; a fixing plate is welded to the top ends of the first clamping blocks; the bottom end of the fixing plate makes contact with the top end of the box cover; a solid impurity filter screen barrel is welded to the bottom end of the fixing plate and matched with the first through hole; a water inlet is formed in the middle of the top end of the fixing plate; lifting handles are symmetrically welded to the outer side of the top end of the fixing plate; an activated carbon filter screen groove is formed in the inner lower part of the box body; and the top end of the activated carbon filter screen groove is connected with an oil-water separation filter screen through a clamping mechanism. According to the invention, solid impurities can be conveniently filtered, and the solid impurities filtered out from the solid impurity filter screen barrel can be conveniently cleaned.

Description

technical field [0001] The invention relates to the technical field of petroleum wastewater, in particular to a petroleum wastewater degreasing and filtering device. Background technique [0002] Petroleum wastewater generally refers to petroleum industry wastewater. It mainly includes three aspects: petroleum extraction wastewater, oil refining wastewater and petrochemical wastewater. Oily wastewater is discharged during the dehydration process of crude oil extracted from oilfields. This wastewater also contains a large amount of dissolved salts, and its specific composition is related to the geological conditions of oil-bearing formations. [0003] Petroleum wastewater is generally recycled using oil removal and filtration devices, and the existing petroleum wastewater removal and filtration devices generally filter and separate petroleum wastewater through oil-water separation filters first, and then filter through other filters Purification treatment. However, in petr...
