A high-efficiency waste water degreasing device

Abstract

The invention provides an efficient wastewater deoiling device which comprises an upper barrel body, a lower barrel body, a skirt seat and basic rings, wherein the barrel bottom of the upper barrel body is connected with the top of the lower barrel body; a structure communicated with the lower barrel body is arranged at the barrel bottom of the upper barrel body; the barrel bottom of the lower barrel body is fixedly connected with the skirt seat; the skirt seat is fixed on the ground through the basic rings; the upper barrel body comprises an upper sieve plate assembly, an upper water distributor, an upper section air outlet pipe, an inlet hole and an upper hollow fiber pipe; the lower barrel body comprises a lower sieve plate assembly, a lower water distributor, a lower section air outlet pipe, a lower hollow fiber pipe and an oil discharging pipeline. Due to the characteristics of the hollow fiber pipes made of modified acrylic materials, small-molecular water can enter the hollow fiber pipes, and macro-molecular oil is left in the barrel bodies, so that oil-water separation is realized; meanwhile, the device treats wastewater in two layers separately, so that the effect is better. The device is flexible in design, suitable for treating oily wastewater with low turbidity and low suspension content, and higher in separation efficiency and structural performance.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a high-efficiency waste water degreasing device. Background technique [0002] With the development of society, oil gradually invades water bodies, forming oily wastewater. The amount of industrial oily wastewater is large and the composition is complex, such as oil extraction and oil processing, refining and transportation, steel rolling water in machinery manufacturing, cooling lubricants, etc., among which oily wastewater from oil extraction is the main source. In modern times, oil extraction has become more and more frequent, and the amount of oily wastewater produced is relatively large. If these oily wastewater is allowed to be discharged, it will not only cause certain harm to the environment, but also waste a large part of resources. For the treatment of oily wastewater, first of all, it should be considered to recover the oil as much as possible for repeated or ...
