Anti-scaling temperature-controlled electric coalescence dehydrator coupled with electric field-ultrasonic field-centrifugal field

Abstract

The invention discloses an anti-scaling temperature-controlled electric coalescence dehydrator coupled with electric collecting field-ultrasonic field-centrifugal field, which includes a thermal insulation system, an ultrasonic generating device and a demulsification device. The demulsification device includes a spiral demulsification chamber and a spiral demulsification chamber The spiral is wound on the insulation system to provide temperature conditions for demulsification through the insulation system; the ultrasonic generator is placed in the insulation system to generate an ultrasonic field; The outside of the demulsification chamber is the positive electrode; it is used to generate an electric field inside the spiral demulsification chamber. The invention combines electric dehydration technology, ultrasonic demulsification dehydration technology, cyclone separation dehydration technology and heat treatment dehydration technology, and synergistically improves the demulsification efficiency of the device.

Description

technical field [0001] The invention belongs to an electric dehydrator, in particular to an electric coalescence dehydrator in the field of petrochemical industry. Background technique [0002] At present, most oilfields in my country use water injection to exploit oil, and because crude oil contains more impurities, most of the extracted crude oil needs to be dehydrated. Compared with methods such as gravity sedimentation, centrifugation, and chemical treatment, the electric dehydration rate is faster, the processing capacity is large, and there is no chemical pollution. The electric dehydrator has lower energy consumption, higher efficiency, safety and simplicity, and has a wider application range, and is more widely used in the dehydration treatment of crude oil. [0003] As my country's requirements for oil recovery technology continue to increase, how to efficiently separate oil from water is an urgent problem to be solved. Electrodes play a vital role in oil-water el...

AI Technical Summary

Problems solved by technology

As more and more oil fields are discovered, due to different geological conditions, the quality of crude oil is not uniform, the viscosity of the produced fluid is high, and there are many impurities carried in it. Common electric dehydrators are prone to scaling on the insulating plate during the treatment process. , and the silt-like deposits formed between the electrode steel plate meshes are difficult to clean up, which will have a negative impact on the normal operation of the electric dehydrator, making the dehydration effect not ideal

In addition, ordinary electric dehydrators occupy a large area, and the construction and operation costs are relatively high.
