A side wall entry gas-liquid distributor, distribution tray and upflow reactor

By using a fiber layer structure in the gas-liquid distributor and a scale-collecting inlet diffuser design in the upflow reactor, the problem of large bubbles agglomerating in the gas-liquid mixture was solved, achieving uniform mixing of the gas and liquid phases and deposition of solid particles, thereby improving the flow characteristics of the reactor and the catalyst utilization rate.

Abstract

A kind of side wall entry type gas-liquid distributor, distribution disc and upflow reactor, belong to chemical equipment field, including the tubular part of top end opening formation gas-liquid mixture outlet, the side wall of tubular part is multilayer structure, and from outside to inside in turn outer skeleton layer, fiber layer and inner skeleton layer, fiber layer is the cylinder made of fiber silk, allow liquid phase to pass through and do not react with liquid phase, outer skeleton layer and inner skeleton layer surface distribution hole structure, to make gas-liquid mixture pass through outer skeleton layer, fiber layer and inner skeleton layer in turn in the direction of vertical tubular part side wall into tubular part, and from gas-liquid mixture outlet flow out.The present application by the side wall of central tube is set to the composite structure of inner and outer skeleton layer clamping fixed fiber layer, makes gas-liquid two-phase mixture with bubble pass through fiber layer into distributor, in this process, make bubble further refine into more smaller micro-bubble, substantially improve the uniformity of gas-liquid two-phase mixing.
