Problems solved by technology

[0003] In the process of petroleum exploration and development, especially when dealing with oil-based drilling fluid-related operations, a large amount of oily cuttings, oily sludge and oily items that pollute the environment will be produced: such as gloves, clothing, felt, cotton yarn, zero Parts, etc. In the past, some oil-containing items were directly disposed of by landfill or incineration, which may cause secondary pollution, and in many cases, most items such as gloves, clothing, and felts are completely contaminated by oil stains just after use, and have to be scrapped. Some of the waste products can be used again after the oil stains are removed, but the existing microwave treatment equipment is only for oily sludge and oily drill cuttings, and there is no clear mention of oil removal treatment for other oily items, and there is no corresponding Technical capabilities, such as patents "Microwave Treatment of Oily Drilling Cuttings Device (Authorized Announcement No.: CN206266402U)", "A Microwave Thermal Desorption Recycling System for Oily Solid Waste (Authorized Announcement No.: CN207271789U)", "Oil-based Drilling Fluid Waste electromagnetic microwave treatment system and method (authorized announcement number: CN102826729B)”

Abstract

The invention relates to the technical field of oil field environmental protection, in particular to a microwave deoiling recovery device for oil-containing articles and an application method thereof.By effectively setting a microwave processor, a vacuum pump, a sprayer, a dust collector, a dry ash collection box, a condenser, an oil-water stratifier, a thermal oxidizer and other components, thedeoiling process of the oil-containing articles has real-time visualization, controllable operation, clean deoiling and reliable performance. The microwave deoiling recovery device for oil-containingarticles and the application method thereof can achieve a more convenient, low-cost, and high-efficiency deoiling treatment effect without external nitrogen blowing by adopting a mode of microwave heating, for-vacuum and water-spraying circulation, so that the material cost is reduced; and the related operations can achieve automatic control, so that the manpower cost is reduced, the operation efficiency is improved, and the application range is wide.
