Gas, liquid and solid three-phase separation system

Abstract

The invention discloses a gas, liquid and solid three-phase separation system which can be used for realizing high-efficiency separation of three phases of gas, liquid and solid. The system comprises a cross flow filter, a gas and liquid coalescer, a front flow dividing container, a rear flow dividing container and a slurry concentrator, wherein a to-be-filtered material charging hole of the cross flow filter is connected with an output end of a to-be-filtered material conveying pipe; a filtered material discharging hole is connected with an input end of a filtered material conveying pipe; a filtered and concentrated material discharging hole is connected with the input end of a concentrated material refluxing pipe; a gas and liquid two-phase material charging hole of the gas and liquid coalescer is connected with the input end of a gas and liquid two-phase material conveying pipe; a gas and liquid two-phase material discharging hole of the front flow dividing container is connected with the input end of the gas and liquid two-phase material conveying pipe; a to-be-filtered material discharging hole is connected with the input end of the to-be-filtered material conveying pipe; the filtered and concentrated material charging hole is connected with the output end of the concentrated material refluxing pipe; a bottom slurry discharging hole is connected with a slurry conveying pipe; the filtered material charging hole of the rear flow dividing container is connected with the output end of the filtered material conveying pipe; the gas and liquid two-phase material discharging hole is connected with the gas and liquid two-phase material conveying pipe; and a to-be-treated slurry charging hole of the slurry concentrator is connected with the slurry conveying pipe.

Description

technical field

[0001] The invention relates to multiphase separation technology, in particular to a gas-liquid-solid three-phase separation system. Background technique

[0002] The fracturing fluid produced in oil extraction is a complex multiphase system with components, and its recovery and treatment is currently a difficult point in the treatment of oil extraction wastewater. If the gas-liquid-solid three-phase substances of the fracturing reverse drainage fluid can be separated efficiently, it will provide prerequisites for the subsequent treatment of these three-phase substances separately, and then develop a more ideal treatment process. Patent Publication Nos. CN102123776A, CN103712845A and other documents provide gas-liquid-solid three-phase separation equipment, but their applications are limited to specific technical fields and lack efficient separation means.
