Two-stage multi-inlet dynamic pressure degasser

Abstract

A two-stage multi-inlet dynamic pressure degasser belongs to the technical field of multi-phase flow separation and is characterized in that a plurality of evenly distributed rectangular tangent inlets are used to ensure uniformity of peripheral flow, a circular passage between an outer wall and an umbrella-shaped rectifying plate is used to carry out pre-degassing, precise separation guide blades are used to arrive at forced vortex, a separation factor is increased via a conical barrel, and precision gas removal is achieved for a bottom flow port. The two-stage multi-inlet dynamic pressure degasser comprises an external mechanism and an internal body; the external mechanism is composed of an upper cover, a coarse separation vortex inlet, a barrel body, a conical barrel, a straight round barrel, and a bottom cover; and the internal body is composed of a coarse separation exhaust pipe, a precise separation exhaust pipe, an umbrella-shaped rectifying plate, and precise separation guide blades. The two-stage multi-inlet dynamic pressure degasser is of two-stage separation structure, can generate a strong vortex field in cooperation with the precise separation guide blades, can provide significantly increased precise removal rate for gas with high gas-liquid ratio, is high in applicability and operational elasticity, is simple in structure and easy to maintain, and is widely applicable to various gas-liquid separation cases.

Description

technical field [0001] The invention relates to a double-stage multi-entry dynamic pressure degasser, which belongs to the technical field of multiphase flow separation. Background technique [0002] The cyclone type degasser is a device that uses the centripetal force difference caused by the difference in oil and gas density during the cyclone process to achieve separation. Widely used in petroleum industry, chemical separation and marine equipment, because of its simple structure, low cost and convenient use, it is gradually replacing the original gravity settling equipment. [0003] Compared with the traditional gravity separation equipment, the cyclone type degasser has the advantages of compact structure, high separation efficiency, large operating flexibility, and can adapt to various working conditions. In the case of large liquid-to-gas ratio and high liquid-phase gas content, the traditional gravity separator has low working efficiency, and the separation effect i...

Problems solved by technology

[0004] In order to overcome the problems in the prior art, the present invention provides a two-stage dynamic pressure degasser, the purpose of which is to use the pre-degassing process to reduce the liquid-gas ratio of the fluid, and at the same time use the guide vanes to generate a strong swirl flow field to increase the fineness. The separation efficiency of the separation can effectively improve the defects of the current cyclone separators that perform poorly under the condition of large liquid-gas ratio
