Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a wastewater treatment device for oil production. Background Technology
[0002] Wastewater generated during oil production has a high oil content. Direct discharge of this wastewater can lead to environmental problems such as eutrophication of water bodies and soil pollution. Therefore, it needs to be treated by wastewater treatment equipment before discharge.
[0003] However, some existing wastewater treatment devices may encounter impurities such as oil sludge in the wastewater when treating wastewater with high oil content, making it inconvenient to separate and treat them. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a wastewater treatment device for oil production. A motor drives a spiral stirring blade to rotate. An ultrasonic generator, combined with the spiral stirring blade, ensures thorough mixing of the demulsifier and wastewater. A valve is then opened to start the feed pump, drawing the mixed wastewater through a discharge pipe. After being pressurized by the pump, the wastewater is transported through a connecting pipe to the hydrocyclone separator. The hydrocyclone separator uses centrifugal force to separate the oil and water in the wastewater. The oil is discharged through an overflow pipe, while oily sludge and impurities are discharged through a slag discharge port, facilitating use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device for oil production, comprising a first fixed frame, a second fixed frame fixedly connected to the top of the first fixed frame, a reaction tank fixedly connected inside the second fixed frame, a feed pipe and an additive pipe provided at the top of the reaction tank, a motor fixedly connected to the top of the reaction tank, the output shaft of the motor movably penetrating and extending into the interior of the reaction tank, a spiral stirring blade fixedly connected to the output shaft of the motor, a cavity provided inside the reaction tank, an ultrasonic generator provided inside the cavity, a discharge pipe provided at the bottom of the reaction tank, a valve provided on the discharge pipe, a material pump provided at the bottom of the reaction tank, the end of the discharge pipe away from the reaction tank being fixedly connected to the input end of the material pump, a hydrocyclone separator body fixedly connected inside the first fixed frame, an overflow pipe provided at the top of the hydrocyclone separator body, and a slag discharge port provided at the bottom of the hydrocyclone separator body.
[0006] Furthermore, the output end of the feed pump is connected to the feed end of the cyclone separator body via a connecting pipe.
[0007] Furthermore, the interior of both the feed pipe and the addition pipe is connected to the interior of the reaction vessel.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] The motor drives the spiral agitator to rotate. The ultrasonic generator, combined with the spiral agitator, ensures thorough mixing of the demulsifier and wastewater. Then, the valve is opened to start the feed pump, which draws the mixed wastewater through the discharge pipe. After being pressurized by the feed pump, the wastewater is transported to the hydrocyclone separator body through the connecting pipe. The hydrocyclone separator body separates the grease from the water in the wastewater using centrifugal force. The grease is discharged through the overflow pipe, while the oily sludge and impurities are discharged through the slag discharge port, making it easy to use. Attached Figure Description
