Underground automatic steady-flow type cyclone separator

Abstract

The invention discloses an underground automatic steady-flow type cyclone separator, which can strength applicability, to a liquid inlet amount unsteady condition, of cyclone separating equipment. Theunderground automatic steady-flow type cyclone separator is characterized in that an inlet liquid processing module and an inverted cone structure are arranged in a variable-diameter separating tube,wherein a plurality of through circular holes are formed in a liquid inlet of the variable-diameter separating tube; the through circular holes are distributed along the periphery of the variable-diameter separating tube; the inlet liquid processing module comprises a large control spring, a static connecting rod spiral runner, a dynamic spiral runner, a step conical disc, a blocking pressure disc and a locking bolt; a blocking slot is formed inside the variable-diameter separating tube for fixing and positioning the static connecting rod spiral runner; the large control spring, the static connecting rod spiral runner and the dynamic spiral runner are assembled together through a lower blocking groove and an upper blocking groove; the inverted cone structure comprises a multi-section-diameter top cone, a rail type inverted cone, a sealing ring and a small control spring; the step conical disc is fixed to the static connecting rod spiral runner through threaded connection; the blockingpressure disc and the step conical disc are fastened through the locking bolt; and the inverted cone structure and the inverted cone fastening base are connected together through threads.

Description

technical field [0001] The invention relates to a downhole multiphase flow separation device applied in the fields of petrochemical industry, environmental protection and the like. Background technique [0002] Today, hydrocyclones have been applied to the fields of oil-water separation in the same well injection and production in oilfields, oilfield sewage treatment and other fields due to their good economical practicability, high separation efficiency, and operational stability. In actual engineering, the separation performance of the hydrocyclone is affected by multiple factors, one of the most important factors is the problem of low separation efficiency due to the unstable liquid intake, so solving the problem of unstable liquid intake at the liquid inlet becomes a problem of improving the cyclone A critical step in the performance of flow separators. At present, the overflow volume of the cyclone is often adjusted to reduce the influence of the instability of the inl...
