Problems solved by technology

[0005] The design of the existing intermediate column generally only considers the rectangular tube column to bear the load alone, without considering the role of other structural components such as wall panels, which undoubtedly greatly increases the consumables of the intermediate column, resulting in great waste, which is not conducive to the dust collector market further development of

Embodiment 1～24

[0059] Examples 1-24: Destruction mechanism of the middle column of the dust collector box under axial pressure

[0060] The present embodiment is as follows to the research method of axial pressure failure mechanism:

[0061] Such as figure 1 As shown, in the dust collector box corrugated board wallboard-rectangular tube column structure system, when the middle column bears axial pressure on the top, the load is not only transmitted to the middle column, but also part of the load is transmitted to the beam and wall panel , and the wall panels on both sides of the column of the box can give the column a large lateral support to prevent its instability. Therefore, the failure form of the middle column is strength failure; image 3 As shown, there are many possible relative connection positions between the middle column and the wallboard in actual engineering. Therefore, when considering the failure mode of the middle column, it is necessary to comprehensively consider various ...

Embodiment 1～3

[0069] Examples 1 to 3: Three different models of Model B, Model C and Model E were taken for analysis. The dust collector box is a perfect structural model. When applying loads to the built finite element model, the wall panel Skin effect, the wall plate will bear part of the load for the column, therefore, the axial load N applied on the top of the column top , it is possible to exceed N cy .

[0070] The finite element ultimate bearing capacity analysis of the perfect structures of Model B, Model C and Model E shows that: (1) Under the axial load, the stress area on the column is mainly concentrated on the top of the column, and the top of the column can realize The entire section reaches the yield strength; (2) For the wall panel, the stress in the area near the column is much greater than the stress in the area away from the column, because the wall panel near the column bears part of the load for the column and plays a larger role. Strong skin effect; (3) The column ma...

Embodiment 4～6

[0072] Embodiments 4 to 6: Considering the influence of the overall bending geometric defect of the upper span of the middle column for Model B, Model C and Model E, the stability coefficients of the three models are also greater than 1 according to calculations, and the load-displacement curves are as follows Figure 11 As shown, it can be obtained that the entire section of the middle column yields, and the lateral deformation is very small, and the failure of the middle column when the upper span is bent as a whole is not an instability failure.

Abstract

The invention discloses a wall plate of a box body of a dust remover. The invention discloses a design method of a middle column in a rectangular pipe column structure and belongs to the technical field of structural engineering. A large number of finite element models are calculated and analyzed on wallboard of box body of dust remover and the rectangular pipe column structure; a fitting formulaof the maximum stress calculation coefficient of the middle upright column section is provided to calculate the axial bearing capacity of the upright column; the cross section area enables the middlestand column to meet the requirement for bearing capacity, consumables of the middle stand column can be reduced as much as possible, the cost of the dust remover box body is reduced, and meanwhile safety, reliability, economy and reasonability of the structural design can be guaranteed.

Description

technical field [0001] The invention relates to a design method for an intermediate column in a dust collector box wallboard-rectangular tube column structure, and belongs to the technical field of structural engineering. Background technique [0002] Dust collector is an environmental protection equipment that can separate dust from flue gas. It is widely used in industries such as thermal power, metallurgy, chemical industry and building materials to eliminate dust. The performance of the dust collector is generally expressed by the amount of gas it can handle, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency; at the same time, the price, maintenance cost and service life of the dust collector are also important factors to consider its performance. [0003] For the dust collector, in addition to the internal dust removal device, its price, maintenance cost and service life are also related to the quality of its enclosure s...
