Problems solved by technology

The specific operation of cuttings reinjection is that the cuttings are injected into the ground after being ground and stored in the hydraulic fractures at the bottom. This method has high processing costs, destroys the underground geological structure, pollutes the oil layer or groundwater, and is not suitable for large-scale treatment of abandoned drilling; The specific operation of cutting and incineration is to heat the oil-based mud to about 500°C in a high-temperature incinerator

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] This embodiment provides a three-phase separation device for oily solid waste, such as figure 1 and figure 2 As shown, it includes a reaction cylinder and an input shaft 1 extending horizontally into the reaction cylinder. The reaction cylinder includes a sealed cavity composed of an input end bearing seat 2, a cylinder body 3 and a discharge end bearing seat 4. The input end bearing seat 2 and the discharge end The center of the bearing seat 4 is respectively provided with an input end bearing 5 and a discharge end bearing 6 which cooperate with the input shaft 1, and there is a gap between the input end bearing seat 5 and the input shaft 1 which is used to fill the sealing packing and is closed by the input end sealing gland 7. The input end sealing chamber 8, the discharge end bearing seat 6 and the input shaft 1 are provided with a discharg...

Abstract

The invention belongs to the field of dewatering and deoiling equipment of solid wastes generated in the oilfield oil production, transportation, storage and refining processes and particularly relates to a device for performing oil, water and slag three-phase separation on oily solid wastes. The invention adopts the scheme that heat is generated through rotor and solid material collision shear friction, and mechanical energy is converted into heat energy, so that a heat source is provided for material temperature rise; the capillary force among materials is damaged, so that the oil, water and slag three-phase separation is performed on the oily solid wastes; a separated product is non-toxic and harmless to the environment, no secondary pollution is generated, recovered oil can be reused, and the solid wastes can reach environmental protection emission standards.

Description

technical field [0001] The invention belongs to the field of dehydration and deoiling equipment for solid waste produced in the process of oil extraction, transportation, storage and refining in oil fields, and in particular relates to a device for three-phase separation of oil, water and slag from oily solid waste. Background technique [0002] Oily sludge is oily solid waste produced during oil extraction, transportation, refining, and oily sewage treatment. It is generally divided into oily sludge from oilfields and oily sludge from petrochemical industries (mainly refineries). Generally, the oil content in sludge is 10-50%, and the water content is 40-90%. According to the calculation of crude oil production and total imported crude oil in 2006, my country's oilfield sludge is about 3 million tons, and refinery sludge is about 980,000 tons. , Nearly half of refinery sludge comes from imported crude oil. Most of my country's oil fields have entered the "three high" develo...
