Gas-solid phase catalytic reactor

Abstract

The invention discloses a gas-solid phase catalytic reactor, which comprises a reactor shell, a catalyst bed layer and a heat exchange device, wherein a gas inlet pipeline extending along the tangential direction of the side wall of the reactor shell is formed on the side wall; the catalyst bed layer is formed in the reactor shell, forms an annular rotational flow cavity together with the reactor shell, and is a hollow cylinder; a shell of the catalyst bed layer is provided with a through hole which is communicated with the inside of the catalyst bed layer; and the heat exchange device is arranged in the catalyst bed layer. According to the gas-solid phase catalytic reactor disclosed by the invention, reaction gas enters tangentially and flows rotationally in the rotational flow cavity, longer retaining time is obtained in comparison to a direct radial gas entering way, and the reaction gas enters the catalyst bed layer after uniformly flowing rotationally and being diffused in the rotational flow cavity for a longer period of time for reacting under the action of a catalyst, so that the reaction gas is distributed more uniformly in the axial space of the entire catalyst bed layer of the reactor.

Description

technical field [0001] The invention relates to the technical field of gas-solid phase catalytic reaction, in particular to a gas-solid phase catalytic reactor. Background technique [0002] In the chemical production process, there are often too many by-products due to factors such as uneven temperature of the catalyst bed in the synthesis reactor, too high reaction temperature, or too low reaction temperature. [0003] For gas-solid phase exothermic catalytic reactions such as methylamine, methyl ether, methanol synthesis, ammonia synthesis and CO shift under pressure, as the reaction proceeds, the heat of reaction released continuously increases the temperature of the catalyst bed. In order to reduce the by-products and improve the efficiency of the reactor, it is necessary to remove the reaction heat so that the reaction temperature is in a reasonable range. One that has been widely used in industrial reactors is a multi-stage adiabatic reaction. The temperature of the ...
