Oil-water separation system for petroleum chemical oil refining

Abstract

The invention relates to the technical field of petrochemical engineering, and discloses an oil-water separation system for petrochemical engineering oil refining, the oil-water separation system comprises a separation mechanism, the top of the separation mechanism is fixedly connected with a separation box, the top of the separation box is provided with a separation plate, and the left side of the top of the separation plate fixedly communicates with water inlet connecting pipes at equal intervals; and one side of the water inlet connecting pipe communicates with an electromagnetic valve, one side of the electromagnetic valve communicates with an external water conveying pipe, and the front side and the rear side of the separation mechanism communicate with water return pipes correspondingly. By improving the oil outlet mechanism, when an oil-water mixture moves from the left side to the right side of the separation mechanism, a suction pipe can pump the oil-water mixture into an oil outlet plate through a pumpback pump and discharge the oil-water mixture into a gathering tank from a lower oil sleeve arranged in the oil outlet plate, and the pumpback pump is arranged in a frequency conversion manner, so that the amount of oil entering the gathering tank can be controlled; in this way, it can be guaranteed that the amount of petroleum passing through the filtering holes can be controlled, the internal filtering stability of the petroleum is guaranteed, and the overflow situation is avoided.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to an oil-water separation system for oil refining in petrochemical industry. Background technique [0002] Petrochemical generally refers to the petrochemical industry, which is an important part of the chemical industry and plays an important role in the development of the national economy. It is one of the pillar industries in our country. Petrochemical refers to the processing industry that uses oil and natural gas as raw materials to produce petroleum products and petrochemical products. Petroleum products, also known as oil products, mainly include various fuel oils (gasoline, kerosene, diesel oil, etc.) and lubricating oils, as well as liquefied petroleum gas, petroleum coke, paraffin, asphalt, etc. [0003] The mixed liquid discharged during the refining process mainly includes water and petroleum, while a large amount of usable petroleum is mixed in the disc...

AI Technical Summary

Problems solved by technology

[0003] The mixed liquid discharged during the refining process mainly includes water and petroleum, while a large amount of usable petroleum is mixed in the discharge liquid discharged during petroleum refining, and in the rough refining method, directly These effluents are discharged into the external environment, and the effluents of refined oil refining are treated by adsorption, so that the internal petroleum residual oil will be absorbed and waste will occur. The oil in the drain is used for oil-water separation and recovery system
