Problems solved by technology

The working temperature of the hydrogenation reactor is relatively high, about 550°C, and the working pressure is high, above 3MPa. When the hydrogenation reactor is working, the fasteners of the equipment flange will cause leakage points on the flange sealing surface due to the slight deformation of the bolts. lead to hydrogenation reactor leak

Embodiment Construction

[0010] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0011] The flange sealing structure of the hydrogenation reactor shown in the accompanying drawings includes an upper flange 1, a lower flange 2, and an omega ring sealing ring 3, and the Ω ring sealing ring 3 is arranged between the connecting end faces of the upper flange 1 and the lower flange 2 . In this embodiment, the hydrogenation reactor flange is a DN900 flange, and the omega ring sealing ring 3 is welded and connected to the upper flange 1 and the lower flange 2 .

[0012] After the present invention adopts the Ω-ring sealing ring 3, since the connecting method between the Ω-ring sealing ring 3 and the hydrogenation reactor flange is welding, when the hydrogenation reactor is working, even if the fastener bolts of the hydrogenation reactor flange have slight deformation , There will be no leakage point between the flanges...

Abstract

The invention discloses a hydrogenation reactor flange sealing structure. The hydrogenation reactor flange sealing structure comprises an upper flange, a lower flange, and an omega-shaped sealing ring, the omega-shaped sealing ring is arranged between connecting end surfaces of the upper flange and the lower flange, and the omega-shaped sealing ring is welded to the upper flange and the lower flange. After the omega-shaped sealing ring is adopted, a connection manner of the omega-shaped sealing ring to the above hydrogenation reactor flanges is welding, so when a hydrogenation reactor works, even fastener bolts of the hydrogenation reactor flanges slightly deform, no leakage points are formed between the hydrogenation reactor flanges, thereby the hydrogenation reactor flanges are reliably sealed, and the continuous work of the hydrogenation reactor is guaranteed.

Description

technical field [0001] The invention relates to chemical reaction equipment, in particular to a hydrogenation reactor flange sealing structure. Background technique [0002] The hydrogenation reactor is a chemical equipment for converting silicon tetrachloride into trichlorosilane. Hydrogenation reactor The lower part of the hydrogenation reactor has an equipment flange, and the upper and lower flanges of the equipment flange must be sealed. The flange sealing structure in the prior art adopts a concave-convex surface or a ring sealing surface. The working temperature of the hydrogenation reactor is relatively high, about 550°C, and the working pressure is high, above 3MPa. When the hydrogenation reactor is working, the fasteners of the equipment flange will cause leakage points on the flange sealing surface due to the slight deformation of the bolts. Leakage in the hydrogenation reactor. Contents of the invention [0003] The invention aims at the deficiencies of the pr...
