A Multi-bed Axial Radial Reactor

Abstract

The invention discloses a multi-bed axial and radial reactor. The reactor comprises a radial cylindrical sealed pressure-bearing shell (2), an air inlet pipe (16), an axial-radial catalytic reaction zone (8) and an air outlet pipe (14), wherein the axial-radial catalytic reaction zone (8) is a cylindrical containing space capable of containing catalyst beds; the containing space is formed by side walls (11), a top seal head (5) and a seal bottom (18); the side walls (11) and the alternative seal bottom (18) are of an opening structure through which fluid can penetrate but solid catalysts cannot penetrate; and the top seal head (5) is of a fluid impenetrable structure. The pressure of the reactor is reduced, the space utilization rate is high, and any gas flow deviation or short-circuit phenomenon is avoided.

Description

technical field [0001] The invention relates to a multi-bed axial radial reactor. Background technique [0002] There are mainly two types of fixed bed reactors, one is axial fixed bed reactor and the other is radial fixed bed reactor. The axial fixed bed reactor is relatively easy to design and process, and simple to operate, but there are problems such as large size of reactor equipment, large pressure drop in the bed layer, prone to local temperature jump, slow heat transfer, low conversion rate, and obvious amplification effect. The radial bed reactor has the advantages of large height-to-diameter ratio, small bed pressure drop, short residence time of reactants in the catalyst bed, low operating cost, high production capacity, can use small particle catalysts, and is easy to scale up. To achieve uniform distribution of reactants in the radial direction. [0003] The advantages and disadvantages of radial bed reactor design have a great influence on the reaction proces...
