An intermittent cyclone separation device

Abstract

An intermittent cyclone separation device. Including water phase outlet pipe, impeller shaft, small bevel gear, large bevel gear, large bevel gear shaft, intermittent rotation mechanism shell, large bevel gear shaft sealing structure, fixed structure, tangential inlet, oil phase outlet pipe, swirl chamber , oil phase baffle, small bevel gear shaft, impeller housing, bypass pipe, tangential outlet, outlet cone, inlet cone, speed regulating pipe, impeller, rotating disc, guide groove, push block, guide column and cross block, etc. . The tangential outlet is an arc structure, the tangential outlet is tangent to the top of the swirl chamber at the end close to the swirl chamber, and the tangential outlet is bifurcated at the end far away from the swirl chamber to form a bypass pipe and a speed regulating pipe. The impeller housing is located on the rotating speed regulating pipe; the impeller is located in the chamber formed by the impeller housing and the rotating speed regulating pipe; the large bevel gear is located outside the intermittent rotating mechanism housing. The invention has the advantages of high separation efficiency, strong system integration, compact structure and 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 ...

Problems solved by technology

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 nuclei and the oil phase. There is more water phase in the annular area formed between the inner walls of the outlet pipe, which will inevitably cause the oil nucleus to flow out with the surrounding water phase, which greatly reduces the efficiency of cyclone separation
