Gas-solid phase catalytic reactor

Abstract

The invention discloses a gas-solid phase catalytic reactor comprising a housing and heat exchanging internal parts, wherein an air inlet and an air outlet are formed in the top and the bottom of the housing respectively; the heat exchanging internal parts comprise a plurality of heat exchanging pipes; two ends of each heat exchanging pipe are connected with the inner wall of the housing respectively; jackets are arranged on the outer wall of the housing at the joints; and a central heat exchanging pipe group can be arranged in the internal center of the housing as required. Due to the housing with a flange coupling end socket, the gas-solid phase catalytic reactor also can be used for reconstruction of the conventional reactors with housings. Due to the special compact pipe arranging manner, the gas-solid phase catalytic reactor has the advantages that the heat exchanging capability is high; the structure is reliable; the manufacture is convenient to manufacture and maintain; the investment is low; and the suitability for new construction and reconstruction of the reactors is high.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a reactor which can be used for gas-solid phase catalytic reaction. Background technique [0002] Fixed bed catalytic reactor is a reaction equipment widely used in the chemical industry and petrochemical industry. For exothermic reactions such as ammonia synthesis, methanol synthesis, and synthesis gas to methane, commonly used fixed bed catalytic reactors include axial reactors and radial reactors. to the reactor. Among them, the axial reactor has a simple structure and a high volume ratio, but due to the limitation of the cross section of the fluid channel and equipment, the bed resistance is relatively large, and the catalyst strength is required to be relatively high. Compared with the axial reactor, the bed resistance of the radial reactor is small, but if the heat is exchanged by water cooling, it is necessary to adopt forced means to circulate the cooling wate...

Among them, the axial reactor has a simple structure and a high volume ratio, but due to the limitation of the cross-section of the fluid channel and equipment, the bed resistance is relatively large, and the catalyst strength is required to be relatively high.

Compared with the axial reactor, the bed resistance of the radial reactor is small, but if the water-cooled heat exchange is used, forced means are required to circulate the cooling water, such as the installation of internal and external gas distribution cylinders, resulting in low volume utilization and complex structure , low catalyst efficiency
