Abstract

A device and method for removing suspended solids in oil products, the device includes at least two stages of air flotation removal sections arranged in sequence from bottom to top, and the porosity of the filler in the upper air flotation removal section is always smaller than that of the air flotation removal section. The porosity of the filler in the lower air flotation removal section, the bottom of the first-stage air flotation removal section is equipped with a microbubble generator, and high and low air volume pulse air intake is adopted to make the suspended matter attached to the surface of the filler uniformly arranged 1. The pores between the fillers are dredged; the present invention adopts low-density fillers, and the fillers are in a non-fixed state in the air flotation removal section. The pulse ventilation makes the fillers rotate or collide, so that the surface of the air flotation fillers is evenly attached to the suspended matter , not only effectively remove the suspended matter in the raw material, but also prevent the filler from being blocked by the suspended matter.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and specifically relates to a device for removing suspended matter in oil products and a method for removing suspended matter by using the same. Background technique [0002] Crude oil contains water and salts such as sodium chloride, calcium chloride, and magnesium chloride. In order not to affect the processing of crude oil, the first step before crude oil enters the factory for processing is desalination and dehydration, so that the water content is 0.1% to 0.2%, and the salt content <5mg / L, and for refineries with residual oil hydrogenation or heavy oil cracking, the requirements are more stringent, and the salt content in raw oil is required to be <3mg / L. Many crude oils contain a certain amount of colloidal suspended matter, which brings more problems to the dehydration and desalination process of crude oil and subsequent processing equipment. , easy to block the flow-...
