Inlet flue triangular truss suspension type denitration reactor device

Abstract

The invention discloses an inlet flue triangular truss suspension type denitration reactor device. According to the device disclosed by the invention, two ends of a top supporting beam of a traditional denitration reactor body extend to a peripheral steel bracket platform of a denitration reactor to be used as a low chord rod of a triangular truss; one triangular truss is arranged above each supporting beam; a hoisting rod is mounted at a node of the low chord rod and is connected with each layer of a catalyst module supporting beam at the lower side; a reactor wall plate is mounted on a peripheral hoisting rod to form the denitration reactor body; an outlet flue is mounted at the lower end of the denitration reactor body; and limiting devices in the horizontal direction are arranged at four sides of the middle part of the reactor respectively to form the suspension type denitration reactor device. The inlet flue triangular truss suspension type denitration reactor device has the beneficial effects that the device can be used for sufficiently releasing structure performance of an original inlet flue, stress characteristics of a whole structure are changed and limitation on the stability and slenderness ratio of a compressed member is avoided; the section of the member is wholly reduced, the self weight is reduced and the cost is saved; and a suspension type structure is utilized so that the earthquake effect on the member also can be reduced.

Description

technical field [0001] The invention relates to the technical field of denitrification, in particular to a denitrification reactor device suspended by a triangular truss of an inlet flue. Background technique [0002] The denitrification reactor device is the core link of the selective catalytic reduction (SCR) flue gas denitrification complete set technology, which is mainly composed of the denitrification reactor body, the inlet flue, and the outlet flue. The traditional structure is that the body of the denitration reactor is supported by four corner columns, the top is connected to the inlet flue, and the bottom is connected to the outlet flue. The main pressure-bearing component is the quadrangular frame column of the reactor. In addition to supporting the overall load of the entire denitrification reactor system, it also bears the horizontal load caused by the internal pressure of the flue. The frame column bears a large load and has a large cross-section. [0003] Th...

AI Technical Summary

Problems solved by technology

[0005] (1) The main components of the traditional denitrification reactor structure are mostly pressure-bearing components, and the overall stability and local stability of the components need to be considered, the slenderness ratio control is stricter, and the cross-section is larger

[0006] (2) The inlet flue is only considered as an independent component, and does not participate in the overall calculation, and does not contribute to the force of the overall structure

[0007] (3) The inlet flue will receive a large thrust under the action of the internal pressure of the flue gas, and the thrust point is far away from the support, and the moment arm is large, forming a large bending moment, which further increases the load on the frame column

[0008] (4) Since the outlet flue is set directly below the denitrification reactor, the fulcrum cannot be added under the internal support beam of the denitrification reactor, only two ends are supported
