Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a mobile oilfield wastewater treatment device. Background Technology

[0002] To achieve higher oil recovery rates, most development wells in my country's oilfields employ water injection, resulting in high water content in the crude oil. In eastern oilfields, the water content of produced fluids has reached 90%. Before external transportation, the water must be removed, creating oily wastewater, the main pollutant of which is crude oil. This oily wastewater primarily originates from bottom water in crude oil dehydration stations and various crude oil storage tanks within combined stations, as well-washing operation water, etc. Oilfield wastewater has a complex composition, with petroleum hydrocarbons and various additives being the main organic pollutants. If this wastewater is not treated and reinjected or discharged in a timely manner, it will not only prevent the normal operation of oilfield surface facilities but also cause environmental pollution and affect safe oilfield production. Therefore, it is essential to rationally treat and utilize oily wastewater. Oilfield wastewater treatment plants are commonly used for wastewater treatment.

[0003] The published patent document with publication number CN218539485U discloses an oilfield wastewater treatment device, which includes a base plate and an activated carbon plate. A support frame is fixedly connected to the top left side of the base plate, a reaction tank is fixedly connected inside the support frame, and a motor is fixedly connected to the top of the reaction tank.

[0004] However, the aforementioned existing technology still has shortcomings in its use. The existing technology filters impurities in wastewater by fixing a filter screen plate to the inner wall of the reaction tank. However, the existing technology is not convenient for workers to clean the impurities filtered off the filter screen plate afterward. The only way to clean it is to turn the whole device upside down and pour out the impurities through the feed pipe on the motor side, which is very inconvenient. Moreover, since the filter screen plate is fixedly installed on the inner wall of the reaction tank, the filtration rate is relatively slow. Therefore, we propose a mobile oilfield wastewater treatment device. Utility Model Content

[0034] This invention provides a mobile oilfield wastewater treatment device. In use, wastewater and flocculant are added to the reaction tank 5 through the inlet pipe 1. The motor 7 is started, driving the rotating gear 8 to rotate, which in turn drives the rotating rod 10 to rotate via the gear ring 9. The rotation of the rotating rod 10 causes the stirring blades 25 to rotate and the circular rotating plate 24 to rotate the filter cylinder 23. The circular baffle 22 prevents impurities inside the filter cylinder 23 from escaping. Impurities in the wastewater are filtered through the rotating filter cylinder 23, and the filtered wastewater is collected inside the reaction tank 5. The stirring blades 25 increase the reaction rate between the wastewater and the flocculant. After the reaction is complete, the connecting pipe 12 is opened, and the water pump 14 is started, supplying water through the delivery pipe. Under the action of pipe 15 and pipe 13, the liquid after the reaction is drawn into the hollow cylinder 16, and then filtered again through the activated carbon plate 26 inside the filter cylinder 19. Finally, it is discharged and collected through the drain pipe 20. After the work is completed, the filter cylinder 19 can be rotated by rotating handle 21, which will cause the internal threaded ring 18 to rotate, thereby separating the internal threaded ring 18 from the hollow cylinder 16. The filter cylinder 19 can then be disassembled, and the activated carbon plate 26 inside the filter cylinder 19 can be slid out for cleaning or replacement. The locking relationship between the cover plate 2 and the reaction chamber 5 is released by locking buckle 4, and then the cover plate 2 is rotated open by hinge 3, so that the circular baffle 22 is separated from the filter screen cylinder 23. Then the bolts are removed, and the filter screen cylinder 23 can be disassembled to clean the impurities.
