Double-introduction-layer tower expanding cavity type separator

Abstract

The invention discloses a double-introduction layer tower expanding cavity type separator which can adapt to large production load variation and can not generate a phenomenon that bubbles are generated when high-speed gas-liquid stirring is carried out so that separation can not be carried out under high load. According to the invention, a unique double-introduction mechanism and multi-layer gradually-expanded separation chamber can ensure that even though the flow and physical property of a separation medium are greatly varied, the separator can adapt to the flow and the physical property; and by means of a Coanda effect namely wall-attached flow of fluid on an expanded wall surface, the fluid nearby a boundary deflects outwardly, axial symmetric circulation current with downward periphery and upward center can be naturally generated, thereby overcoming the self-sustained oscillation caused by clash impact of inner current in a pure cylinder chamber and reflect current at the bottom of the pure cylinder chamber. Multiple units of cyclone sedimentation separators can be combined and used, so that the separation space is saved, the separation efficiency is high, operation is stable, and the variable working condition adapting property is good. The double-introduction-layer tower expanding cavity type separator can be widely suitable for occasions such as oil-gas separation, water-gas separation, solid-liquid separation and dedusting separation.

Description

technical field [0001] The invention belongs to the technical field of centrifugal cyclone settling separation of multiphase components, and is suitable for gas-solid phase, liquid-solid phase, and liquid-droplet-containing gas-liquid phase medium, under the working condition that the flow rate varies widely. for efficient separation. Background technique [0002] Settling and centrifugal cyclone separators are the most widely used types of multiphase separators in industry. The sinking type relies on gravity to promote the sinking and floating of heavy and light phases, which requires a large settling surface. Centrifugal cyclone relies on centrifugal force field for strong separation, which has high efficiency. Generally, the sedimentation separator (tank) is often accompanied by centrifugal separation at the inlet, so that the heavy component is attached to the inner wall of the container and settles, and the light component floats up and gathers to the outlet, and then...

Problems solved by technology

It is not only troublesome to use multiple devices in parallel to cut off and put into operation, but also increase the cost. If the working conditions change too frequently, it will fall into a failure state if it cannot keep up with the operation
