Description

Technical Field

[0001] The utility model relates to the technical field of oilfield sewage treatment, in particular to a sewage purification device used for environmental protection of oil and gas field projects. Background Art

[0002] During the exploitation process of oil fields, for high-permeability, loosely cemented sandstone reservoirs, sand is easily produced in the formation due to its shallow burial. On the one hand, due to the scouring effect on the formation of sandstone reservoirs, the sand particles in the formation fall off more and more, resulting in the continuous increase of sand carrying in the produced fluid. On the other hand, after the sewage treated by the produced fluid has been running in the reinjection system for a long time, impurities such as calcium and magnesium ions in the water are easy to scale. Under the action of the scouring force, the scale is easy to be eroded and fall off, forming larger granular mechanical impurities in the sewage. These impurities often lead to damage to the water injection pump, pipeline blockage, water meter jamming, and formation blockage.

[0003] The Chinese patent publication number is CN215947030U, a sewage purification device for oil and gas field engineering environmental protection, the technical solution provided by the patent document is: including: a filter box, a connecting pipe and a sterilizing box, the two ends of the connecting pipe are respectively fixedly connected to the bottom of one side of the filter box and the top of one side of the sterilizing box, and the bottom of the filter box and the sterilizing box are fixedly connected with a bottom plate. In the utility model, through the cooperation of the filtering mechanism, the disinfecting mechanism and the sterilizing mechanism, the existing oilfield sewage treatment device solves the problem that most of the debris in the sewage is not broken in time and flows away with the sewage because most of them use the impact block to reciprocate to break the debris in the sewage, and the effect of quickly and continuously breaking the debris in the sewage is achieved. At the same time, the problem that the existing oilfield sewage treatment device only filters and purifies the sewage, resulting in unsatisfactory sewage treatment effect, is solved, and the effect of heating, disinfecting and sterilizing the sewage is achieved at the same time.

[0004] In order to solve the problem that the natural sedimentation method is used in the prior art to remove the above-mentioned mechanical impurities and sand particles, the sewage is naturally precipitated in a container large enough, but the natural sedimentation method has a high investment cost; and since the above-mentioned mechanical impurities and sand particles are naturally settled in the container, it takes sufficient time to complete, and thus the work efficiency is low, the prior art uses a rotating roller to drive the crushing blades and one of the gears to rotate, and then another gear drives another rotating roller and the crushing blades to rotate, so that the sewage that continuously falls in the water inlet pipe can be processed by crushing the debris. However, it is inconvenient to concentrate the impurities after sewage separation, which leads to increased processing costs and is not conducive to environmental protection. Utility Model Content
