A self-adjusting support for a denitrification reactor relates to a combined self-adjusting support for large non-standard equipment. The invention includes rigid supports and support beams connected to the reactor. Its structural feature is that a heat insulating block and an angle adjustment mechanism are sequentially connected between the rigid support and the support beam. The heat insulation block is a steel box body with supporting ribs in the middle, and a plurality of convection circular holes are opened on each side plate of the box body. The angle adjustment mechanism includes an upper seat plate, a convex spherical middle plate and a lower seat plate. In the middle of the upper surface of the lower seat plate is a concave spherical surface and the convex lower surface of the convex spherical middle plate forms a first sliding surface, and the lower surface of the upper seat plate and the upper surface of the convex spherical middle plate form a second sliding surface. Compared with the prior art, the present invention can automatically adjust the contact angle between the rigid support and the support beam under the state of load loading and temperature rise, so as to maintain the original stress direction of the structural frame beam and fundamentally improve the bearing capacity of the structural beam. power status.
Description
technical field [0001] The invention relates to a combined self-adjusting support for large non-standard equipment, in particular to a self-adjusting support for a denitrification reactor. Background technique [0002] With the deepening of national environmental protection requirements, major thermal power plants are doing further treatment of flue gas emissions to reduce air pollution. Among them, the core equipment in flue gas denitrification is the denitrification reactor. The operating temperature of the denitrification reactor is about 400°C, and a large number of heavy catalyst modules are installed inside it, and the weight of these catalysts accounts for 40-50% of the overall equipment. In the prior art, the weight of the overall equipment of the denitrification reactor is acted on the structural frame beams through the supporting columns 3 of the reactor body and the surrounding rigid supports 4 . When no catalyst load is added, the bottom surface of the rigid su...
