Special ultrasonic dirty oil sludge deoiling equipment for oil field

Abstract

The invention relates to special ultrasonic dirty oil sludge deoiling equipment for an oil field. The special ultrasonic dirty oil sludge deoiling equipment comprises an ultrasonic dirty oil sludge separation system (1) and an oil-water and solid-liquid separation system (2), wherein the ultrasonic dirty oil sludge separation system (1) can convey dirty oil sludge to an ultrasonic dirty oil sludge separation tank (1-1); an ultrasonic transducer (1-4) fixed on the ultrasonic dirty oil sludge separation tank (1-1) is used for carrying out ultrasonic vibration on dirty oil sludge in the ultrasonic dirty oil sludge separation tank (1-1); crude oil is separated from the dirty oil sludge subjected to ultrasonic vibration by the ultrasonic transducer (1-4) through the oil-water and solid-liquid separation system (2). By adopting the equipment, the problems of high energy consumption, environment pollution and complex process in the process of separating crude oil from the dirty oil sludge in the prior art are solved and the equipment has the characteristics of high dirty oil sludge treatment speed, high efficiency, high flexibility and high mobility.

Description

technical field [0001] The invention relates to equipment for deoiling sewage sludge, in particular to equipment for deoiling equipment with ultrasonic equipment for oilfield special ultrasonic sludge deoiling. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Sludge is a common solid waste in the process of oil extraction, storage and processing. The oily sludge has a high content of petroleum pollutants, so it is included in the "National List of Hazardous Wastes". At present, solvent extraction, hot water washing, thermal decomposition and biological treatment are commonly used in the treatment of sludge in China. [0004] The solvent extraction method is more complex and time-consuming in the treatment of sludge. The hot water washing method needs to select the appropriate alkaline hot water according to t...

AI Technical Summary

Problems solved by technology

This scheme has the following disadvantages: First, the treatment process for sludge in this scheme is relatively complicated, and the equipment involved is high in energy consumption, and too many equipment means higher risk and maintenance cost for the series working system

Secondly, the form of the transducer is the horn type, and the range of the oil sludge it acts on is small, and it is difficult to achieve high power due to the limitation of the structure of the horn type transducer, so the treatment of sludge The speed has a certain degree of influence, and the matching of the action time and the flow rate cannot be achieved

Thirdly, because the scheme involves more operating equipment, it needs the support of a larger site, so the site selection and environmental protection put forward higher requirements
