Description

Technical Field

[0001] This utility model relates to the field of catalyst lifting pipeline technology, and in particular to an anti-vortex tooling and system based on a catalyst lifting pipeline. Background Technology

[0002] Flanges on catalyst riser pipelines typically use RJ seals. Because the octagonal gaskets used with RJ seals are thicker than ordinary spiral wound gaskets, the flange gap between double flanges on catalyst riser pipelines is relatively large (e.g., ...). Figure 1 As shown in the diagram, the booster gas will form eddies here, causing wear on the catalyst booster pipe. Utility Model Content

[0003] In response to the aforementioned technical problems, an anti-vortex tooling and system based on a catalyst booster pipe is provided.

[0004] The technical means adopted in this utility model are as follows: In a first aspect, an anti-vortex tooling based on a catalyst booster pipe includes an anti-vortex gasket, the anti-vortex gasket comprising a gasket body, a first gasket protrusion, and a second gasket protrusion; the gasket body is annular, the inner diameter of the gasket body is equal to the inner diameter of the first flange and the inner diameter of the second flange, and the outer diameter of the gasket body is equal to the inner diameter of the octagonal gasket; both the first gasket protrusion and the second gasket protrusion are annular, the axial cross-section of the first gasket protrusion and the axial cross-section of the second gasket protrusion are both spike-shaped, the flat ends of the first gasket protrusion and the flat ends of the second gasket protrusion are coaxial and fixedly installed on both sides of the gasket body in the axial direction, and the distance between the tip of the first gasket protrusion and the tip of the second gasket protrusion is equal to the thickness of the flange gap between the first flange and the second flange.

[0005] Furthermore, both the first gasket protrusion and the second gasket protrusion are provided with a plurality of protrusions.

[0006] Furthermore, the anti-eddy current gasket is made of the same material as the octagonal gasket.

[0007] In a second aspect, an anti-eddy current system based on a catalyst lifting pipeline includes a first flange, a second flange, and an octagonal gasket; the first flange and the second flange are coaxial and oppositely arranged, and the octagonal gasket is coaxial and fixedly installed between the first flange and the second flange, with a flange gap formed between the first flange, the second flange, and the octagonal gasket; it also includes an anti-eddy current fixture based on a catalyst lifting pipeline as described in any one of the first aspects; the outer side of the gasket body of the anti-eddy current fixture based on the catalyst lifting pipeline is in contact with the inner side of the octagonal gasket; the inner side of the gasket body of the anti-eddy current fixture based on the catalyst lifting pipeline is located on the same cylindrical surface as the inner side of the first flange and the inner side of the second flange; the tips of the protrusions of the first gasket and the second gasket of the anti-eddy current fixture based on the catalyst lifting pipeline respectively contact the two sides of the flange gap in the thickness direction.

[0008] This utility model has the following advantages: 1. In this utility model, the anti-vortex gasket is installed in the flange gap. At this time, the outer side of the gasket body is in contact with the inner side of the octagonal gasket. The inner side of the gasket body, the inner side of the first flange, and the inner side of the second flange are located on the same cylindrical surface. The protruding tips of the first gasket and the second gasket respectively contact the two sides of the flange gap in the thickness direction, thereby preventing the lifting gas from forming vortices in the flange gap. This prevents the catalyst particles from breaking due to collision, causing abnormal dust generation during the lifting process. It also prevents the catalyst particles from wearing down the catalyst lifting pipe due to collision, thereby preventing abnormal leakage caused by the accelerated thinning rate of pipe wear.

[0009] 2. In this utility model, the anti-eddy current gasket can also prevent the increase of dust generation and has better high temperature performance and expansion margin. Attached Figure Description
