Abstract

The invention discloses a gas-liquid two-phase multi-stage cyclone separation device. The separation device comprises an air inlet, a jacket cylinder, guiding nozzles, a cyclone separation cavity, a collector, a slotted vortex finder and an air outlet. The air inlet and the jacket cylinder are cylindrical, the axis of the air inlet is vertical to the central line of the jacket cylinder in an axial direction, and the air inlet is communicated with the outer wall of the jacket cylinder in the tangential direction. There are a plurality of rows of guiding nozzles. The guiding nozzles are uniformly distributed in the peripheral direction of the cyclone separation cavity. The working processes of the provided device are as follows: a gas and liquid two-phase flow goes into the jacket cylinder through the air inlet and forms an eddy flow in a jacket layer, and a primary separation process is formed; crude particles are separated and sink down at the bottom of the jacket layer, fine particle and the air flow go into the cyclone separator through the guiding nozzles, under action of the guiding nozzles, a strong eddy flow is formed in the separator, and a secondary separation process is formed; under action of a centrifugal force, solid particles are separated from air, and the separated solid particles are conveyed to the collector.

Description

technical field [0001] The invention relates to a multi-stage cyclone separation device, which is suitable for various petroleum, chemical, mining and other industries, and can finely separate two-phase mixed species of gas and solid. Background technique [0002] Gas-solid separator is an important equipment for separating regenerated catalyst and flue gas in petrochemical catalytic cracking system. In a conventional separator device, the separation of gas and solid particles is usually carried out in a chamber. The separation process is limited, the rotation strength is not enough, and the dust remixing problem caused by the vortex lateral circulation directly affects the separation effect of solid particles, especially fine particles and gas, and reduces the separation efficiency. Due to the low separation efficiency of small particles, after treatment, a large number of remaining small particles are discharged into the atmosphere, which can easily cause smog. In order ...
