Abstract

The invention discloses a supporting apparatus for a flue gas denitration reactor. The supporting apparatus comprises a supporting apparatus body; the supporting apparatus body comprises a support having an upper base plate and a lower base plate, a locking pull bar, a limiting pull bar, a disc spring and a displacement indicator, wherein the locking pull bar is tightly fixed between the upper base plate and the lower base plate of the support in advance, the top and bottom ends of the limiting pull bar are respectively provided with a left-handed nut and a right-handed nut, a gap is provided between the nut at the bottom end of the limiting pull bar and the lower base plate of the support, the disc spring is installed between the upper base plate and the lower base plate of the support, and the displacement indicator is vertically arranged, matches with the disc spring and can display displacement of the disc spring. The apparatus provided in the invention has a simple structure, is convenient to install, has a protective cover, can adapt to open-air arrangement, does not need maintenance, examination or repair, can effectively compensate for deflection displacement of a structural beam generated under load-effect of the reactor, enables load-effect points to be maintained at a same horizontal plane and allows load to be linearly uniformly distributed.

Description

technical field [0001] The invention relates to a support device for a flue gas denitration reactor, belonging to the technical field of denitration reactors. Background technique [0002] The flue gas denitration reactor is a rectangular cross-section steel structure loaded with multi-layer catalysts and providing denitrification chemical reduction reaction. The reactor is arranged in an overhead high-rise and operates under high temperature and negative pressure. Its load is evenly transmitted to the external steel structure beams through the rigid support of the reactor load-bearing wall. [0003] The conventionally designed flue gas denitrification reactor directly transmits the load to the external steel structure beam through its own rigid support. Power condition is unreasonable. In addition, the rigid contact between the structural beams and the reactor supports has no cushioning when operating loads fluctuate, adversely affecting the reactor and catalyst. Conten...
