Oil-water separator for petroleum refining

Abstract

The invention discloses an oil-water separator for petroleum refining. The oil-water separator structurally comprises an automatic clean-up mechanism, handles, a water inlet flange, a sewage discharging opening, a water draining opening, a door lock catch, a control switch, a box door, and an electric power storage box, wherein the upper end of the automatic clean-up mechanism is fixedly providedwith two handles or more, the automatic clean-up mechanism and the handles are of an integrally-formed structure, the water inlet flange is fixedly welded on the left side of the automatic clean-up mechanism, the water inlet flange is communicated with the automatic clean-up mechanism, and the electric power storage box is fixedly welded on the front end of the automatic clean-up mechanism and isfixedly connected by virtue of a bolt. The separated oil is scraped by an oil skimmer and collected into an oil storage box to be pumped by an oil suction pipe, the sewage unavoidably contains a givenamount of floating oil when entering a clean water area, and an expansion graphite layer arranged in the clean water area can adsorb and remove the floating oil, so that an oil-water separation effect can be achieved, the oil can be effectively separated from the water, the oil is collected, and the residual oil is effectively adsorbed.

Description

technical field [0001] The invention is an oil-water separator used for petroleum refining, which belongs to the technical field of petroleum refining. Background technique [0002] The main working principle of the oil-water separator is to apply the theory of fluid mechanics. At the moment when the large flow of oily sewage is uninterrupted and synchronous (the oil and water are at the same speed, that is, relatively turbulent flow), the oil droplets continuously collide with the kinetic energy of the high-speed flow of the sewage, and change from small to large. Larger, thereby accelerating the movement, so that oil and water with different specific gravity are divided, stratified and separated, and finally the purpose of oil-water separation is realized. In the crude oil extraction process of petroleum, oil-water separation is an indispensable step. The existing oil-water The separator only has the function of separating oil and water, and cannot calculate the ratio of o...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an oil-water separator for petroleum refining, to solve the problem that the existing oil-water separator usually uses a slag removal hopper to intercept floating and suspended matter, because the slag removal hopper The capacity is limited, often after the slag removal hopper is full, the floating and suspended solids enter the separation area, which affects the separation of oily sewage
