Problems solved by technology

[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.

Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing.

[0012] Referring to accompanying drawing 1, the present invention comprises through-hole 1, bore cylinder 2, outer grid 3, inner grid 4, rigid ring 5 and rigid rib 6. The inside of the reactor is provided with a perforated cylinder 2 and two layers of grids welded inside and outside the perforated cylinder 2, the catalyst is filled therebetween, and the inner grid 3 and the outer grid 4 have the same structure. The lower end of the hole tube 2 is welded with the chemical equipment, and the through holes 1 are evenly distributed on the surface of the hole tube 2 to facilitate material circulation; several rigid rings 5 ​​are perpendicular to the axis of the hole tube 2, and a plurality of rigid ribs 6 are connected to the hole tube The axes of 2 are parallel, and the rigid ring 5 and the rigid rib 6 are uniformly welded on the outer surface of the hole tube 2 to form a combi...

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.
