Problems solved by technology
The radial rigidity of the entire grid support ring is very large, and a large radial stress will be generated when the rectification tower is running; this plane support method does not conform to the structural characteristics of the packing plate itself, and it is easy to cause the axial deformation of the packing plate. Thereby reducing the rectification efficiency of the rectification tower

Embodiment
[0015] In the present invention, the angular aluminum frame 4 uniformly distributed in the circumferential direction is mainly used to support the hoop of the packing plate, and bear the weight of the entire packing plate; the annular plate frame is mainly used to support the packing, and the circumferential support can ensure that each corrugation of the packing The plates can be effectively supported; the radially arranged reinforcing plates are best used for large-size packing pans, and it is better to use when the packing corrugated plates themselves are not rigid enough. The combination of the annular plate frame and the angular aluminum frame in the present invention is a placed structure, which ensures that the rectification tower will not generate stress caused by the support ring during operation.

The invention discloses a filler support device. The filler support device mainly comprises a support ring arranged on the inner wall of the barrel body of a rectification tower, and used for supporting the filler disc composed of a filler and a hoop, wherein the support ring is composed of at least four angular aluminium frames peripherally arranged on the same plane of the inner wall of the barrel body of the rectification tower and at least one annular plate frame additionally arranged on the angular aluminium frames, the hoop is supported by the angular aluminium frames, and the annular plate frame supports the filler; at least two reinforcing plates intersected at the central point of an annular plate are radially arranged at the middle of the annular plate frame; a corrugated plate filler is annularly supported by the annular plate frame. The filler support device has the advantages that the support area can be reduced, so that the efficiency of the rectification tower can be improved, the filler support device meets the intrinsic structural characteristics of the filler disc in the support structure, the deformation of the filler disc can be effectively reduced, and a positive role in energy conservation and consumption reduction of the whole rectification tower is achieved, and the like.
Description
technical field [0001] The invention relates to a packing support device, which is mainly used in the technical field of support for structured packing discs of rectification towers. Background technique [0002] As a part of the rectification column, the support device of structured packing is generally considered to be its strength, but few people consider the influence of the support device on the efficiency of the entire rectification column. The existing packing support device is composed of a common grid-type packing support ring, the support surface of which is flat, the grid is welded by longitudinal slats and transverse side bars, and the grid is welded to the ring plate. The radial rigidity of the entire grid support ring is very large, and a large radial stress will be generated when the rectification tower is running; this plane support method does not conform to the structural characteristics of the packing plate itself, and it is easy to cause the axial deforma...
