Multi-fluid jet quench radial flow reactor

Abstract

The invention discloses a multi-fluid jet quench radial flow reactor, which comprises a radial reactor shell (2), and is characterized in that: a plurality of radial catalyst beds (3) are arranged in the shell (2); each radial catalyst bed (3) is provided with a radial flow external distribution cylinders (4) and a central radial flow internal gas collection cylinder (5); central mixing pipes (9)are arranged in the radial flow internal gas collection cylinders (5); multi-fluid jet quenchers (7) are arranged on the internal upper ends of the central mixing pipes (9); internal spray nozzles (12) and external spray nozzles (13) are arranged in the quenchers (7); the internal spray nozzles (12) are communicated with second quench fluid inlet pipes (8); the external spray nozzles (13) are communicated with first quench fluid inlet pipes (6); and gas mixing chambers for supplying quench gas for the radial catalyst beds (3) on a lower layer are arranged between adjacent radial catalyst beds(3), and the gas mixing chambers are communicated with the radial flow internal gas collection cylinders (5) and the central mixing pipes (9) at the same time. The reactor has the advantages of noveland simple structure, good temperature regulation performance, high operation quality and low manufacturing cost.

Description

technical field [0001] The invention relates to a chemical reactor, in particular to a chilled radial flow reactor, in particular to a fluid jet chilled radial flow reactor using multiple cold fluids as chilling sources. Background technique [0002] At present, typical chilled shock reactors are mainly axial flow reactors ( figure 1 ), consisting of a cylindrical outer cylinder and an internal multi-layer axial flow catalyst bed. There are many cold air pipes between each bed layer to introduce cold shock gas for direct cooling (removal of heat of reaction). With the increase in production capacity and considering the factors of resistance, this type of reactor will present three major problems. [0003] First, the diameter of the reactor is getting bigger and bigger (some have exceeded 12m), and the height of each catalyst bed is getting thinner and thinner (some are only 0.3m), so that the gas flow in the reactor passes through the distribution of the catalyst bed It is...
