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.

specific Embodiment

[0048] The SCR denitrification reactor device of an ironworks in Shanghai, the seismic fortification intensity of this project is 7 degrees, the design basic seismic acceleration value is 0.13g, the design earthquake grouping is the first group, the site category is second class, and the basic wind pressure is 0.40KN / m 2 ; The size of the denitrification reactor is 10.20m*6.60m*12.00m (height), and the height of the inlet flue is 1.65m. The overall model is calculated and subjected to force analysis in the structural design software, and finally the cross-sections of the triangular truss chord and the components of the denitrification reactor body are determined as follows: figure 1 shown.

[0049] During installation, the two ends of the support beam 2 (support rectification grid and inlet flue) on the top of the traditional denitrification reactor are extended to the peripheral steel support platform of the denitrification reactor as the lower chord of the triangular truss 6...
