Three-phase separation equipment for oil-containing silt (sand)

Abstract

Three-phase separation equipment for oil-containing silt (sand) is disclosed. The three-phase separation equipment comprises a stirring reaction tank, wherein a stirrer capable of rotating is arrangedin the stirring reaction tank; a rotor pump or auger conveying mechanism for feeding the oil-containing silt is arranged on one side of the stirring reaction tank, and a blending water tank for feeding an acid liquid agent solution into the stirring reaction tank is arranged on the other side of the stirring reaction tank; an oil taking mechanism is arranged at the inclined upper part of the stirring reaction tank; the oil taking mechanism comprises a gear pump, a flexible oil sticking hose and an oil tank; two meshed gears are erected at the upper end of the stirring reaction tank, the flexible oil sticking hose for sticking oil is arranged between the two meshed gears in a penetrating manner, and an explosion-proof motor for driving the two gears to rotate reversely is arranged above the stirring reaction tank; a sewage purifier is arranged at the outer lower part of the stirring reaction tank; floating oil and suspended solids in water are removed through agent addition, coagulation and air flotation; the sewage purifier is communicated with the middle lower part of the stirring reaction tank; a silt (sand) discharging tank is arranged at the bottom of the stirring reaction tank, and is communicated with the bottom end of the stirring reaction tank.

Description

technical field [0001] The present invention relates to a kind of, more specifically, it relates to a kind of three-phase separation equipment of oily sediment (sand). Background technique [0002] At present, a large amount of oily sludge and sand will be produced in various links of domestic and foreign crude oil development, production, refining, pipeline transportation, and transportation. , sand, sand, and water in a multi-phase mixed state, which is a solid waste and cannot be used directly. These wastes cannot be discharged casually, otherwise it will cause serious environmental pollution. [0003] Due to the large amount of oily sediment produced in the oil field all the year round, and the accumulation continues to increase, it has been piled up in the open environment for a long time and cannot be processed, occupying a large amount of land resources and causing direct pollution to the environment. Scour contaminated soil and water sources. This problem has been...

Problems solved by technology

[0002] At present, a large amount of oily sludge and sand will be produced in various links of domestic and foreign crude oil development, production, refining, pipeline transportation, and transportation. , sand, sand, and water in a multi-phase mixed state, which is a solid waste and cannot be directly used

These wastes cannot be discharged casually, otherwise it will cause serious environmental pollution.

[0003] Due to the large amount of oily sediment produced in the oil field all the year round, and the accumulation continues to increase, it has been piled up in the open environment for a long time and cannot be processed, occupying a large amount of land resources and causing direct pollution to the environment. Flush contaminated soil and water

This problem has been a difficult problem left over in this field for many years, and there is still no effective solution
