Microwave degradation treatment unit for solid wastes of oil field

Abstract

The invention discloses a microwave degradation treatment unit for solid wastes of an oil field. The microwave degradation treatment unit for the solid wastes of the oil field comprises a material conveying pipeline, a low-temperature negative-pressure drying unit, a steam conveying pipeline, a gas-water pipeline, a concentrated material forming system and a microwave degradation drying device, wherein an outlet of the material conveying pipeline is connected with a charge port of the low-temperature negative-pressure drying unit, and an outlet of the steam conveying pipeline is connected witha steam inlet of the low-temperature negative-pressure drying unit; and the low-temperature negative-pressure drying unit comprises a dying machine box body, a concentrated material outlet is formedin the right side of the bottom of the dying machine box body, the concentrated material forming system is connected with the concentrated material outlet, a discharge port of the concentrated material forming system is connected with a charge port of the microwave degradation drying device through a belt conveyor; an inlet of the gas-water pipeline is connected with a heat exchange steam outlet of the low-temperature negative-pressure drying unit; the concentrated material outlet is connected with a secondary steam conveying pipeline; and a steam conveying fan is installed on the secondary steam conveying pipeline. The microwave degradation treatment unit for the solid wastes of the oil field is capable of treating the solid wastes comprising different components, of the oil field, and realizes harmless and resourceful treatment for the solid wastes of the oil field.

Description

technical field [0001] The invention belongs to the technical field of oilfield solid waste treatment, and in particular relates to a microwave degradation treatment unit for oilfield solid waste. Background technique [0002] In the exploitation and exploration of the oil industry, drilling fluid is an essential substance to ensure the normal operation of the drilling process, and the discharge of solid waste depends on the drilling depth. The components of pollutants contained in oilfield drilling solid waste are not easily biodegradable under natural conditions. If the drilling solid waste is left untreated for long-term storage or landfill, harmful substances will cause serious pollution to soil, surface water and groundwater. And directly or indirectly cause harm to human beings, animals and plants. At present, the treatment of oilfield drilling waste is generally to discharge solid waste through solid-liquid separation and other methods, and the solid and liquid waste...

AI Technical Summary

Problems solved by technology

The incineration method is burned in proportion to the fuel, which will produce secondary pollution

The chemical cleaning method uses emulsifiers to break the emulsion and recover the oil phase, which consumes a lot of water, and the resulting oil-water mixture causes secondary pollution

When the microbial metabolic degradation method is used, it is not conducive to oil recovery. At the same time, the aromatics contained in the oil are relatively high, which can inhibit microbial metabolism, resulting in a long decomposition cycle.

[0004] In summary, the oilfield solid waste treatment devices in the prior art have the problems of incomplete treatment and low treatment efficiency
