Pretreatment device for oily sludge

Abstract

The invention relates to the technical field of oily sludge treatment, in particular to a pretreatment device for oily sludge. According to the invention, emulsion nucleus aggregation of the oily sludge can be increased, so that the oily sludge is destabilized, the emulsified state is broken, the pretreatment effect is better, the subsequent treatment pressure is reduced, and the device is more practical; the device comprises a filter and a dehydrator, the device further comprises a first core treatment unit, a feeding pipe, a first connecting pipe and a second connecting pipe; a first switchvalve is arranged at the output end of the front side of the first connecting pipe; a second switch valve is arranged at the rear side output end of the first connecting pipe; a first cavity is formedin the first core processing unit; a first ultrasonic demulsification assembly, a first high-frequency vibration assembly and a first high-energy electron beam assembly are fixedly arranged in the first cavity; the input end of the second connecting pipe is communicated with the output end of the first core processing unit, the output end of the second connecting pipe is communicated with the input end of the dehydrator, and a third switch valve is arranged on the second connecting pipe.

Description

technical field [0001] The invention relates to the technical field of sewage oil treatment, in particular to a pretreatment device for sewage sludge. Background technique [0002] As we all know, oil sludge treatment refers to the sludge generated during the production process of oil fields or refining enterprises due to crude oil extraction, storage, gathering, processing, and crude oil production fluid treatment. It contains crude oil or some of the crude oil The ingredients are well-known, mainly divided into: landing sludge, tank cleaning sludge, flotation scum, refining waste oil, etc.; the pretreatment device for sludge Oil and other pretreatment equipment, which is widely used in the field of sludge treatment, the existing pretreatment device for sludge includes filters and dehydrators; when the existing pretreatment device for sludge is used, the sludge is passed through The filter is used for filtration treatment, and then the solid-liquid separation can be realiz...

It contains crude oil or some of the crude oil The ingredients are well-known, mainly divided into: landing sludge, tank cleaning sludge, flotation scum, refining waste oil, etc.; the pretreatment device for sludge Oil and other pretreatment equipment, which is widely used in the field of sludge treatment, the existing pretreatment device for sludge includes filters and dehydrators; when the existing pretreatment device for sludge is used, the sludge is passed through The filter is used for filtration treatment, and then the solid-liquid separation can be realized through the desilter; the current pretreatment unit structure of the sludge is single, and it is difficult to break the emulsified state of the sludge through the filter and the desilter, and the pretreatment effect is not good, resulting in subsequent Increased processing costs and limited use
