Problems solved by technology

[0007] In view of the lack of equipment in the prior art that can effectively remove suspended solids in oil products, the device is easily blocked during the removal process, and the removal is not complete, which greatly affects the subsequent desalination effect. The present invention provides a method for removing oil products The device and method for medium-suspended solids have a good effect of removing suspended solids and high treatment efficiency

Embodiment 1

[0032] A device for removing suspended solids in oil, such as figure 1 As shown, it includes the primary air flotation removal section 2 and the secondary air flotation removal section 4 arranged in sequence from bottom to top, the primary air flotation removal section 2 is filled with a primary air flotation packing layer 3, and the filler is a large Cellular honeycomb packing with a density of 550kg / m 3 , with a porosity of 65% to 70%; the secondary air flotation removal section 4 is filled with a secondary air flotation filler layer 5, and the filler is a macroporous honeycomb filler with a density of 570kg / m 3 , with a porosity of 25% to 30%; the above fillers are all polypropylene fillers; the bottom of the primary air flotation removal section 2 is provided with a microbubble generator 1, and the inlet of the microbubble generator 1 is provided with a controllable gas volume The low air volume intake valve 9 and the high air volume intake valve 10, the inlet pipeline of...

Embodiment 2

[0034] The device for removing suspended solids in oil products, except that the primary air-floating packing layer 3 is a large-porous wire mesh packing with a porosity of 70% to 75%, and the secondary air-floating packing layer 5 has a porosity of 20% to 25%. Except, other structure and arrangement mode are the same as embodiment 1.

Abstract

The invention discloses a device and a method for removing suspended matters in an oil product. The device comprises at least two stages of air floatation removal sections, which are sequentially arranged from bottom to top, wherein the porosity of the filler in the air floatation removal section on the upper layer is always smaller than that of the filler in the air floatation removal section onthe lower layer, a microbubble generator is arranged at the bottom of the first-stage air floatation removal section, and high-air-volume and low-air-volume pulse type air intake is adopted, so that suspended solids attached to the surfaces of the fillers are uniformly distributed, and pores among the fillers are dredged. In the invention, the low-density filler is adopted, wherein the filler is in a non-fixed state in the air floatation removal section, and the filler works in a manner of self-rotation motion or collision motion through pulse type ventilation, so that the suspended solids areevenly attached to the surface of the air floatation filler; as a result, the suspended solids in raw materials are effectively removed, and the filler can be prevented from being blocked by the suspended solids.

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-...
