Background

In the sewage treatment processes such as oil fields, refineries, chemical plants and the like, large-area devices are often built to separate mixed liquid, such as a settling basin or a settling tank, an air flotation device, oil separation, filtration and fixed liquid level recovery, but the recovery of floating liquid can be untimely in the operation process, the treatment efficiency is low, the energy consumption of high liquid level liquid inlet is large, the treatment effect is unsatisfactory, and the cost is very high. And because the oily sewage contains a large amount of silt, suspended matters and other impurities.

In the sewage sedimentation process, the method is an important link, and separation is carried out by gravity sedimentation by utilizing different densities of two media. The separated floating liquid is effectively recovered, so that the purpose of separating the mixed liquid is achieved, and a plurality of large storage tanks are required to be built for separating the mixed liquid in sewage treatment industries such as oil fields, refineries, chemical engineering and the like. The adopted separation process is that the mixed liquid is injected into the container through a fixed liquid level, the mixed liquid is settled for a certain time, and the light medium floats on the liquid surface by utilizing the different densities of the mixed liquid and is collected by a fixed liquid collecting mechanism.

Therefore, the fixed liquid distribution is adopted in the sedimentation process, so that the liquid which just floats on the liquid surface is mixed with the incoming liquid, and the repeated sedimentation and separation are formed. Resulting in waste of time and energy. And adopt fixed mode of receiving liquid in the in-process of receiving the liquid, can only control the floating liquid layer near the liquid groove of receiving and can collect, and be less than the liquid groove and appear the evacuation phenomenon, be higher than the liquid groove and can get rid of other dense media to form malignant sedimentation once more and separate, especially to the oil-water separation technology, can cause certain environmental pollution.

In order to reduce the labor force of workers during maintenance, the surface floating liquid is collected at any time, the separation time of the mixed liquid is shortened, and a higher separation effect is achieved. Therefore, the liquid distribution, separation and collection can be reasonably and effectively carried out, which is a system problem.
