Vertical oil-gas separator for separating petroleum

Abstract

The invention discloses a vertical oil-gas separator for separating petroleum. The structure of the vertical oil-gas separator for separating petroleum includes a sealing end cover, a device body, aninlet and an oil outlet; the sealing end cover is installed on the upper end of the device body; the inlet is arranged on the left side of the device body, and the oil outlet is arranged on the rightside; the device body is equipped with a gas outlet, a pressure control valve, a mist trap, a buffer plate, an oil collection tank, and a separation cavity; the gas outlet is matched with the pressurecontrol valve; and the inside of the separation cavity is equipped with the mist trap, the buffer plate and the oil collection tank. According to the invention, a liquid squeezing piece and a connecting block are arranged, and the driving wheel is matched with a connecting slide rail, when the mixture is sprayed on the bottom surface of the plate, the formed oil layer is driven in the same direction by the driving wheel through the liquid squeezing piece, so that the oil in the oil layer is scraped from the bottom of the plate body, so as to prevent the formation of thick grease stain on theplate body and causing the impact on the buffering process of the plate body.

Description

technical field [0001] The invention relates to the technical field of oil separation, in particular to a vertical oil-gas separator for oil separation. Background technique [0002] The oil-gas separator is a device that separates the crude oil produced by the oil well from the associated natural gas. The oil-gas separator is placed between the submersible centrifugal pump and the protector. The oil-gas mixture enters the body from the oil inlet and passes through the energy absorber. After spraying on the buffer partition, the dissolved natural gas in the crude oil is freed due to the pressure drop and the diffusion effect, and the separated oil falls to the bottom by its own weight, and is discharged from the oil outlet after being broken by the foam breaking net, carrying small The natural gas in the oil droplets is discharged from the gas outlet after passing through the gas rectifier and the mist trap. There is a layer of oil remaining on the surface. For a long time,...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a vertical oil-gas separator for oil separation, which is used to solve the problem of oil liquid being sprayed onto the buffer baffle and leaving a layer of oil on the bottom surface of the baffle due to the poor fluidity of the oil. Therefore, the oil continuously accumulates to form a thick layer of grease. With the residual grease on the buffer partition, the buffer partition bears a certain weight, which hinders the normal operation of the buffer partition and the technical problem of low buffer efficiency.
