Reactor with framework fortified aperture plate

Abstract

The invention relates to a chemical reactor used in petrochemical production, in particular to a reactor with frame and enhanced grid. The external surface of the hole cylinder is fixedly connected with a plurality of rigid ribs vertically and with a plurality of rigid rings horizontally; the rigid ribs and the rigid rings are crossly connected to form a plurality of gridding frames; the welding strip network is embedded into each gridding frame, is attached to the external surface of the hole cylinder and is fixedly connected with the rigid ribs and the rigid rings; the internal surface of the hole cylinder is also fixedly connected with the rigid rings, and the welding strip network is embedded into the gridding frame formed by the neighboring rigid rings. The reinforced frame structure can improve the overall rigidity of grid, effectively prolong the service life of grid, reduce deviation of grid spacing, improve utilization rate of catalyst and ensure long-term and stable operation of a reactor.

Description

technical field [0001] The invention relates to a chemical reactor for petrochemical production, in particular to a reactor with a frame-reinforced grid. Background technique [0002] In petrochemical production, the chemical reactor is the core equipment of the device, with harsh operating conditions, high technical content, complex structure and large investment. The catalyst grid is the weak link of the reactor, whether the grid manufactured in China or the grid imported from abroad is relatively easy to damage, and the more serious damage is usually caused by the collapse of the lower part of the grid due to the axial folds and the distortion of the circumference. The main reason is the instability caused by the insufficient rigidity of the grid, and the rigidity of the two-layer grid is insufficient, and the distance between them is not easy to control, which will seriously affect the reaction effect and product quality, shorten the service life of the catalyst and cann...

[0002] In petrochemical production, the chemical reactor is the core equipment of the device, with harsh operating conditions, high technical content, complex structure, and large investment

The catalyst grid is the weak link of the reactor, whether the grid manufactured in China or the grid imported from abroad is relatively easy to damage, and the more serious damage is usually caused by the collapse of the lower part of the grid due to the axial folds and the distortion of the circumference. The main reason is the instability caused by the insufficient rigidity of the grid, and the rigidity of the two-layer grid is insufficient, and the distance between them is not easy to control, which will seriously affect the reaction effect and product quality, shorten the service life of the catalyst and cannot achieve ideal use.
