Chromium alloy flange mouse cage water-cooled motor refining sewage desalting treatment instrument

Abstract

The invention relates to a refining sewage desalting treatment instrument, in particular a chromium alloy flange mouse cage water-cooled motor refining sewage desalting treatment instrument. The instrument comprises a settling pond, a multi-medium filtering unit, an activated carbon filtering unit, a safety filtering unit, a three-stage suite fine filter, an ion exchange unit, a reverse-osmosis concentrated water oxidation unit and a flange energy recycling reverse-osmosis assembling unit; as the improvement, a pressurizing flanged joint, a pressure-relief flanged joint, a low-pressure flanged joint and a pressure-storage flanged joint are arranged on a pressure exchange flange supercharger, wherein the pressurizing flanged joint comprises a volute outlet flange sealing surface and a high pressure switching flange sealing surface and a bolt-nut component and a flange sealing gasket; a volute outlet flange through hole is formed on the volute outlet flange sealing surface; a high pressure switching flange through hole is formed on the high pressure switching flange sealing surface; the bolt-nut component penetrates the volute outlet flange through hole and the high pressure switching flange through hole; a pressure raising flange pump is driven by a mouse case I type water-cooled motor; the flange connecting structure is convenient to mount, dismantle and maintain.

Description

technical field [0001] The invention relates to a refinery wastewater desalination treatment device, which belongs to the technical field of oil and gas field surface engineering, and specifically refers to a refinery sewage desalination treatment device with a chrome alloy flange squirrel cage water-cooled motor. Background technique [0002] Reverse osmosis is a desalination treatment technology that has developed rapidly in recent years and has been studied more. It has been widely used in seawater desalination, boiler water replenishment in power plants, and high-purity water production for electronic industry production. At present, foreign reverse osmosis technology has been successfully applied in refining and chemical enterprises. Knoblock and others in the United States combined membrane filtration with bioreactors for advanced treatment of refinery wastewater. The long-term operation of the device is very stable and the treated water quality is excellent. [0003] ...

AI Technical Summary

Problems solved by technology

[0003] However, the quality of water treated by reverse osmosis depends on the density of the osmotic membrane. The higher the density, the higher the purity of the treated water. At the same time, it is required to increase the pressure of the pretreated sewage participating in the osmosis, which will inevitably increase the engineering cost. Electricity consumption

The existing reverse osmosis technology has problems such as low reverse osmosis concentrated water treatment capacity and high power consumption in the process of treating refinery sewage
