Intermittent swirl separator

Abstract

An intermittent swirl separator is provided. The swirl separator comprises a water phase outlet pipe, an impeller shaft, a small bevel gear, a big bevel gear, a big-bevel-gear shaft, an intermittent rotation mechanism shell, a big-bevel-gear shaft sealing structure, a fixing structure, a tangential inlet, an oil phase outlet pipe, a swirl chamber, an oil phase baffle, a small bevel gear shaft, animpeller shell, a bypass pipe, a tangential outlet, an outlet cone, an inlet cone, a rotation speed adjusting pipe, an impeller, a rotation disc, a guide slot, a pushing block, a guide column, a cross-shaped block, and the like. The tangential outlet has an arc-shaped structure. One end of the tangential outlet, close to the swirl chamber, is tangential to the top end of the swirl chamber, and theend of the tangential outlet, far from the swirl chamber, is forked into the bypass pipe and the rotation speed adjusting pipe which are two liquid flow passages. The impeller shell is on the rotation speed adjusting pipe. The impeller is in a chamber formed by the impeller shell and the rotation speed adjusting pipe. The big bevel gear is outside the intermittent rotation mechanism shell. The swirl separator has the advantages of high separation efficiency, strong system integration, a compact structure and a low cost.

Description

technical field [0001] The invention relates to a cyclone separation device applied in the fields of petroleum, chemical industry, environmental protection and the like, which is aimed at separating two-phase immiscible media with density differences. Background technique [0002] Compared with other types of separation methods, hydrocyclones that use centrifugal separation methods for separation of immiscible media have the advantages of compact structure and rapid separation. At present, hydrocyclones have been widely used in the fields of petroleum exploration, chemical industry and municipal environmental protection. The separation principle of the hydrocyclone is to use the density difference between immiscible media for centrifugal separation, and its separation efficiency is directly affected by the density difference of the multiphase medium to be separated and the particle size of the dispersed phase and other physical parameters. However, in the field of oilfield ...

However, in this process, the oil nuclei in the central area are dynamically formed and continuously discharged, which will largely cause the diameter of the oil nuclei to be small, so that the inside of the oil phase outlet pipe is divided between the oil nucl...
