A sludge prevention and real-time treatment system

Abstract

The invention relates to a sewage sludge prevention and real-time treatment system, which is characterized in that the system comprises: a filter tank; a first sewage pipe, which is inserted and fixed in the filter tank; the top of the first sewage pipe The bottom and the bottom are respectively covered with cover plates, and the cover plate at the bottom is provided with a number of through holes for the filtered sewage to pass through; the second sewage pipe, one end of several second sewage pipes are alternately arranged on both sides of the first sewage pipe ; Filtration device, the filter device is sleeved and fixed on the outside of the first sewage pipe; the scraping device, the filter device is sleeved on the outside of the first sewage pipe; the motor, the motor is fixed on the filter tank, and the output shaft of the motor extends into the filter The device tank body is fixedly connected with the scraping device; the differential pressure gauge, and the two differential pressure gauges are respectively arranged at the liquid inlet and the liquid outlet; It is used in the field of offshore oilfield sewage treatment.

Description

technical field [0001] The invention relates to a sludge prevention and real-time treatment system, which belongs to the petroleum field. Background technique [0002] The enhanced oil recovery method of polymer flooding has become one of the important methods for increasing reserves and production in Bohai Oilfield. Compared with water flooding, the production fluid of polymer flooding contains residual anionic polymers, and the composition of the production fluid is complex and the viscosity increases. , which greatly increases the difficulty of processing. [0003] The traditional oilfield polymer flooding sewage treatment process generally includes three processes of inclined plate, air flotation, and dual-media filtration, and is equipped with necessary water treatment chemicals, such as cationic water purifiers. After the cationic water purifying agent reacts with negatively charged polymers and oils, it will flocculate to form viscous "sludge flocs", and the "sludge ...

AI Technical Summary

Problems solved by technology

After the cationic water purifying agent reacts with negatively charged polymers and oils, it will flocculate to form viscous "sludge flocs", and the "sludge flocs" will continue to accumulate in the equipment, and will gradually form excellent elasticity and stability. On the one hand, it affects the sewage treatment effect, on the other hand, the formed sludge is difficult to treat due to its high oil content, high viscosity, and difficult dehydration.

[0004] However, the existing offshore platform water treatment process does not include the process of real-time treatment of sludge flocs. The sludge flocs accumulate and age for a long time, and their performance becomes more and more stable. On the one hand, it will affect the sewage treatment effect. Due to the characteristics of high oil content, high viscosity and difficult dehydration, the sewage sludge is difficult to deal with
