Profile control equipment for re-pulverizing oil sludge with particle size of lower than 0.5cm by utilizing high pressure hydraulic energy and working method of profile control equipment

Abstract

The invention relates to profile control equipment for re-pulverizing oil sludge with particle size of lower than 0.5cm by utilizing high pressure hydraulic energy and a working method of the profile control equipment. The profile control equipment comprises a hopper, a first high pressure line, a pulverizing separation chamber, a second high pressure line, a high pressure sprayer and a slurry storage tank, wherein one end of the first high pressure line and the second high pressure line both communicate with a high pressure water source, the discharge hole of the hopper communicates with the first high pressure line, the other end of the first high pressure line is connected with the pulverizing separation chamber, the pulverizing separation chamber is arranged at the upper part of the slurry storage tank, the upper part of the pulverizing separation chamber is a cone, the lower part of the pulverizing separation chamber is a cylinder, a plurality of sieve pores are formed in the wall of the cone, the second high pressure line stretches to the bottom in the pulverizing separation chamber, the high pressure sprayer is arranged on the second high pressure line, high pressure water sprayed by the high pressure sprayer impacts oil sludge along the tangential direction of the transverse circle of the pulverizing separation chamber, and an outlet is formed in the bottom of the slurry storage tank. According to the invention, existing high pressure water source is used for impacting and pulverizing the oil sludge, consumption of other energies is completely avoided, massive manpower and material resources are saved for the profile control operation, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to a profile control device and a working method thereof, which utilize high-pressure water energy to re-crumble oil sludge with a particle size of less than 0.5 cm, and belong to the technical field of oil field water plugging and profile control. Background technique [0002] Oily sludge is oily sludge. A large amount of oily sludge is produced in the process of oil extraction, transportation, refining and oily sewage treatment, because oily sludge contains a large amount of benzene series, phenols, anthracene, pyrene and other toxic substances with odor , if not handled properly, it will not only pollute the environment, but also cause huge waste of energy. [0003] At present, the treatment methods of oily sludge mainly include incineration, biological method, solvent extraction method, oily sludge profile control, etc. Among them, oily sludge profile control can not only completely solve the pollution problem of oily sludge t...

AI Technical Summary

Problems solved by technology

This patent has the following defects: (1) The profile control agent material is limited to powdery materials, and it is difficult to realize normal profile control operations for materials such as oily solids that are easy to agglomerate; (2) The screw pump is directly connected with the high-pressure adjustment pump, which will The pressure shock caused by the high-pressure regulating pump affects the normal working process and service life of the high-pressure regulating pump

[0007] To sum up, the existing profile control equipment or profile control methods either cannot effectively realize the pulverization of oil sludge, or consume a lot of manpower and material resources, resulting in a lot of waste of resources and polluting the environment
