Solid-liquid separation device for petroleum refining

Abstract

The invention discloses a solid-liquid separation device for petroleum refining, relates to the field of solid-liquid separation for petroleum refining, and solves the problem that when an existing solid-liquid separation device for petroleum refining is used, petroleum is easy to adhere to the surface of a filter screen, so that the filtering speed is greatly reduced after long-time use, and the separation efficiency is influenced. Comprising a centrifugal base, a separation device and a cleaning device, a device frame is fixedly connected to the centrifugal base, a hydraulic push rod is fixedly connected to the device frame, a mounting frame is fixedly connected to the centrifugal base, a cylinder is rotationally connected to the mounting frame, and a connecting block is fixedly connected to the output end of the hydraulic push rod. By arranging the separation device and the cleaning device, when the separation device moves downwards, petroleum gradually flows to the position above the separation device, when the separation device moves upwards, the opening is closed, so that the petroleum above the separation device is pushed out, and when the separation device completely pushes out the petroleum in the barrel, the cleaning device is linked to rapidly scrape the petroleum on the surface of the separation device.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation for petroleum refining, in particular to a solid-liquid separation device for petroleum refining. Background technique [0002] Petroleum is a viscous, dark brown liquid known as the "blood of industry." There are petroleum reserves in some areas in the upper crust of the earth. The main components are mixtures of various alkanes, naphthenes and aromatic hydrocarbons, which are one of the main objects of geological exploration. The solid impurities are removed, and then the next step of refining is carried out. [0003] The existing Chinese patent CN112495041A discloses a solid-liquid separation device for petroleum refining. In this application, the oil mixture is centrifugally treated by the principle of centrifugal force through the filter screen cylinder, the oil outlet and the receiving shell, so that the liquid oil is Under the action of centrifugal force, it penetrates thr...

Problems solved by technology

[0003] The existing Chinese published patent CN112495041A discloses a solid-liquid separation device for petroleum refining. In this application, the oil mixture is centrifugally treated by using the principle of centrifugal force through the filter cylinder, the oil outlet and the material receiving shell, so that the liquid oil is Under the action of centrifugal force, it penetrates the filter screen cylinder and collects through the material receiving shell to realize efficient solid-liquid separation treatment of the petroleum mixture. However, the device disclosed in this application still has certain shortcomings in the actual use process. First, The greater the viscosity of oil, the greater the tension. If the filter screen can filter the fine solids in the oil mixture, the pore size of the filter screen is very small. Due to the high tension of oil, the speed of filtering liquid oil through the filter screen under the action of centrifugal force is still very slow. , cannot achieve high-efficiency separation. If high-efficiency separation is to be achieved, the pore size of the filter must not be small, so that the fine solids in the petroleum mixture will not be separated cleanly. Therefore, we propose a Solid-liquid separation device
