Problems solved by technology

At present, the baffle structure of the baffle type oscillating flow tube reactor that has been researched and applied is mostly a flat orifice type baffle (single hole or porous). When applied to a reaction fluid system containing more solid particles, Solid particles are easy to accumulate above the baffle (when the reactor is installed vertically) or in front and behind (when the reactor is installed horizontally), so that the reactor cannot run continuously and stably for a long time
This shortcoming limits the application of this type of reactor for solid-liquid catalytic or non-catalytic reaction systems

Embodiment Construction

[0021] Cone ring baffle oscillating flow tubular reactor is composed of an oscillation generating mechanism 1, an inlet section 2, a reaction tube 4, and an outlet section 7 connected in sequence. A discharge port 8 is provided, and the reaction tube 4 is composed of vertically arranged circular reaction tubes. Conical ring baffles 11 arranged in an orderly vertical direction are arranged inside the tube to divide the space inside the tube into a multi-chamber structure.

[0022] The reaction section can be composed of multiple reaction tubes connected in series or in parallel to provide sufficient reaction space and residence time. The multiple reaction tubes are connected with connecting elbows.

[0023] The conical ring baffles 11 inside the reaction tube are connected and positioned by the baffle positioning rod 12, so as to keep the spatial position of each baffle and the distance between the baffles.

[0024] A heat exchange jacket 3 is arranged on the outside of the re...

Abstract

An oscillating flow type tubular reactor with annular conic barrier plates is composed of oscillation generating mechanism, inlet segment with inlet, reaction segment formed by vertical circular reaction pipe with internal annular conic barrier plates for dividing its internal space into several chambers, and outlet segment with outlet. It is suitable for the reaction of liquid-solid suspension system with high content of solid.

Description

technical field [0001] The invention relates to a reactor, in particular to a cone ring baffle oscillating flow tube reactor. Background technique [0002] Oscillating flow reactor is a new type of chemical equipment with broad industrial application prospects, suitable for liquid phase or multiphase flow reaction process dominated by liquid phase. Oscillating flow reactors have excellent transfer characteristics and relatively uniform residence time distribution at very low average flow rates, and in many cases provide better reaction performance than ordinary tubular reactors and stirred tank reactors . At present, the baffle structure of the baffle type oscillating flow tube reactor that has been researched and applied is mostly a flat orifice type baffle (single hole or porous). When applied to a reaction fluid system containing more solid particles, Solid particles are easy to accumulate above the baffle (when the reactor is installed vertically) or in front and behin...
