An oil-water separation device for petrochemical refining

Abstract

The invention belongs to the technical field of petrochemical industry, and in particular relates to an oil-water separation device for oil refining in petrochemical industry. The center of the bottom wall of the cavity is fixedly connected with a support column, which is a vertical square column. The support column is slidably connected with a water level detection component and an oil level detection component. The water level detection component is located below the oil level detection component. The same side of the detection component is fixedly connected with a liquid discharge member. The present invention can respectively detect the interface between the water surface and the oil-water mixture and the interface between the oil-water mixture and the oil surface by setting the water surface detection component and the oil level detection component, and can realize the liquid drainage time required for judging by the height of the oil-water mixture layer, and Realize automatic liquid drainage for the water layer and oil layer, avoiding the discharge of the oil-water mixture during the process of drainage and oil discharge.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, in particular to an oil-water separation device for oil refining in petrochemical industry. Background technique [0002] Petrochemical refining is a process of distilling crude oil or other oils to change the molecular structure, that is, cracking crude oil into kerosene, gasoline, diesel, heavy oil and other fuels suitable for internal combustion engines. [0003] The existing patent (notification number: CN211946543U) is a petrochemical oil-water separation equipment, including a base and a separation box. The outer surface of the separation box is fixedly connected with a fixing frame, and the bottom of the fixing frame is fixedly connected with a support rod. The bottom end of the support rod is fixedly connected with the top of the base, and the top of the fixed frame is provided with a filter mechanism behind the separation box, and the separation mechanism is arranged on th...

AI Technical Summary

Problems solved by technology

[0004] Before refining, the crude oil must be treated first, and the water inside the crude oil must be discharged. After the treatment, the chemical refining operation can be carried out. Although the above-mentioned patent can achieve the effect of oil-water separation in the process of use, the above-mentioned patent is in use. There are the following problems: in the process of oil-water separation through gravity sedimentation, there are usually oil layers, oil-water mixed layers, and water layers during separation, and the ratio of oil to water in different batches of sewage is different, which leads to the actual required settlement. The time and the position of the oil-water interface after settling are different. Therefore, in the separation process, after the water and oil are pumped out, the water layer and the oil layer will be mixed with oil-water mixture, which makes the actual separation effect difficult to achieve the expected goal.
