Ultrasonic radiation appliance for recycling oil extraction sewage

Abstract

The invention discloses an ultrasonic radiation appliance for recycling oil extraction sewage. The ultrasonic radiation appliance comprises an ultrasonic generator, an ultrasonic transducer and a filter element, wherein the filter element comprises a filer element internal circular tube and a filter net arranged outside the filter element internal circular tube, the ultrasonic transducer comprises a stainless steel round tube-shaped body welded on the filter element internal circular tube, the stainless steel round tube-shaped body is internally provided with a containing cavity, a piezoelectric ceramic piece, an electrode plate and an ultrasonic reflection block are fixed in the containing cavity through fixing bolts, positive and negative poles are elicited from the electrode plate through a connecting cable and extend out from an outgoing line port on the containing cavity so as to be electrically connected with the ultrasonic generator, the outgoing line port is provided with a seal part, and an insulated isolation part is arranged between the stainless steel round tube-shaped body and the piezoelectric ceramic piece. The ultrasonic radiation appliance can realize online treatment, is convenient to use, has lasting effect and low energy consumption, has obvious effect in directly impacting on polymers, has no secondary pollution, and has very low running cost.

Description

technical field [0001] The invention belongs to the field of ultrasonic technology, and in particular relates to a technology for treating oil extraction wastewater by physical filtration, which can break bonds and reduce viscosity of polymers in wastewater, thereby improving the treatment effect of oil extraction wastewater treatment processes in oilfields and meeting the requirements of water injection quality. radiation device. Background technique [0002] During the production process of the oil field, a large amount of oil production wastewater such as oilfield production water, well washing wastewater, drilling wastewater and downhole operation wastewater will be generated. With the continuous development and expansion of the petroleum industry, new pollution sources are constantly produced, and a large amount of oil production wastewater is produced at the same time. Pollutants in oil production wastewater enter the environment through various channels, causing a ce...
