An enhanced method, system and process for ultrasonic demulsification of oily sludge

Abstract

The invention provides a reinforcement method, system and technology of oil-containing sludge ultrasonic demulsification. The reinforcement method includes the steps of filling oil-containing sludge with micro-nano bubbles, and conducting ultrasonic demulsification treatment on the oil-containing sludge filled with the micro-nano bubbles. The reinforcement system includes an demulsification pool,an ultrasonic amplitude-change pole capable of moving is arranged at the middle of the demulsification pool and is connected with an ultrasonic transducer, a first micro-nano bubble generator is arranged at the bottom of the demulsification pool, an oil-containing sludge inlet of the demulsification pool is formed in a side wall of the lower portion of the demulsification pool, a sludge outlet ofthe demulsification pool is formed in a side wall of the lower portion of the demulsification pool, and the side wall where the oil-containing sludge inlet is formed is opposite to the side wall wherethe sludge outlet is formed. According to the reinforcement method, system and technology of oil-containing sludge ultrasonic demulsification, a micro-nano bubble technology is utilized for assistingultrasonic waves in reinforcing demulsification effects of heavy and poor-quality oil-containing sludge; the method is continuous and efficient, the quantity of consumed chemical reagents during treatment is greatly reduced, and the treating efficiency of the heavy and poor-quality oil-containing sludge is improved.

Description

technical field [0001] The present disclosure relates to the technical field of ultrasonic demulsification of oily sludge, in particular to a strengthening method, system and process for ultrasonic demulsification of oily sludge. Background technique [0002] The information in this background section of the present disclosure is only intended to increase the understanding of the general background of the present disclosure, and is not necessarily regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Oily sludge, referred to as oily sludge, is an oily solid or fluid waste produced in the process of oil extraction, transportation, refining and oily sewage treatment. The emulsification system in which water and other organic and inorganic substances are firmly bonded together has the characteristics of refractory, toxic, and harmful. If it is directly stacked in the natural env...

AI Technical Summary

Problems solved by technology

[0006] (1) A large amount of demulsifier is added, and the sludge treatment cost is too high, which affects the quality of the sludge;

[0007] (2) The oil sludge agglomerates greatly, the dehydration system is prone to failure, and it is difficult to meet the water quality standard in the subsequent process;

[0008] (3) A large amount of waste liquid that cannot be recycled and reused is produced, and the reuse rate of reagents is low;

[0009] (4) The chemical composition and emulsion structure are complex, and it is difficult for the demulsifier to penetrate into the sludge;

[0010] (5) There is a long oil-water transition zone, which affects the stabilization of ultrasonic waves;

[0011] (6) High energy consumption and low quality of oil sludge after treatment
