Embodiment 1

[0028] A homogenization method based on a sludge homogenization reaction device, comprising the following steps:

[0029] (1) Add oil sludge and water to the feed port of the oil sludge homogenization reaction device, and the weight ratio of oil sludge and water is 1:2.

[0030] (2) Turn on the motor 1, control the rotor speed to 6000r / min, and the running time to 3min.

[0031] (3) After the treated oil sludge slurry enters the centrifuge through the collection port for further dehydration and oil removal, the remaining solids are collected to detect the oil content.

[0032] Using the technology of the present invention, homogenization treatment is carried out for Daqing oil sludge (oil content 15%), and the oil content of oil sludge after treatment is 1.8%, which reaches the current general industry standard "Pollution Control Standard for Comprehensive Utilization of Oilfield Oily Sludge" (DB23 / T1413-2010) is a 2% requirement.

Embodiment 2

[0034] A homogenization method based on a sludge homogenization reaction device, comprising the following steps:

[0035] (1) Add oil sludge and water to the feed port of the oil sludge homogenization reaction device, and the weight ratio of oil sludge and water is 1:2.

[0036] (2) Turn on the motor, control the rotor speed to 6000r / min, and run for 3 minutes.

[0037] (3) After the treatment, the sludge slurry enters the centrifuge through the collection port for further dehydration and oil removal.

[0038] (4) Add the oil sludge collected after dehydration and degreasing, water and inorganic mineral restoration agent from the feed port of the sludge homogenization reaction device, wherein the weight ratio of the oil sludge collected after dehydration and degreasing to water is 1:1, The amount of restoration agent added is 20% of the weight of the sludge.

[0039] (5) Turn on the driving motor, control the rotor speed to 3000r / min, and the running time to 2min.

Abstract

The invention discloses an oil sludge homogenization reaction device and a homogenization method. The oil sludge homogenization reaction device comprises a motor, a tank body, a feed inlet, a homogenization head and an outlet, the feed inlet and the outlet are arranged on two sides of the tank body, and the homogenization head is arranged in the tank body. According to the oil sludge homogenization method disclosed by the invention, the oil sludge is scattered into fine particles through a strong shearing effect and a turbulence effect generated by high-speed stirring of a multi-stage homogenizing head, so that the effects of homogenizing and crushing an oil sludge sample are achieved, and the dehydration and oil removal effects of the treated oil sludge are good. Under the condition that an inorganic mineral repairing agent is added, the oil sludge and the repairing agent are fully mixed and reacted in water, so that the oil content of the oil sludge is effectively reduced. The homogenization method disclosed by the invention effectively overcomes the defects of poor effect and high energy consumption of other homogenization methods, has the characteristics of simplicity in operation and low energy consumption, and has the advantages of good dehydration and oil removal effects of the treated oil sludge and remarkable reduction and recycling effects of oil sludge treatment.

Description

technical field [0001] The invention relates to the field of oil sludge harmless treatment, in particular to an oil sludge homogenization reaction device and a homogenization method. Background technique [0002] Sludge refers to the sludge mixed with heavy oil such as crude oil or refined oil and residual oil through various channels for various reasons, usually composed of water-in-oil (w / o), oil-in-water (o / w) and solid suspension stable suspoemulsion system. Oil sludge has complex components, high viscosity, poor dehydration effect and high difficulty in treatment. [0003] The homogenization treatment of oil sludge can improve the dehydration and oil removal effect of oil sludge, and is a necessary process to realize the harmless treatment of oil sludge. The homogenization of oil sludge requires the addition of a large amount of surfactant, which is carried out under the condition of heating and stirring. It is usually necessary to install heaters, heat exchangers and...
