Example 1
The present embodiment provides a demister support beam, as shown in fig. 1, comprising a beam body, a support plate 104 and a fixing assembly.
Wherein the beam body comprises two side support structures 102, a top plate 101 and a bottom plate 103. The top plate 101 is attached to the top ends of the two side support structures 102 and the bottom plate 103 is attached to the bottom ends of the two side support structures 102. The top plate 101 and the bottom plate 103 are horizontally arranged, the two side supporting structures 102 are vertically arranged plate-shaped structures, that is, the two side supporting structures 102 are side plates, the top plate 101, the bottom plate 103 and the two side plates of the beam body enclose a rectangular frame-shaped beam body, and the top plate 101 is suitable for bearing demister modules.
The support plate 104 is disposed between the two side plates and inside the beam body frame, and the support plate 104 is parallel to the top plate 101. The distance between the top ends and the bottom ends of the two side plates in the vertical direction is H, namely the height of the beam body is H, the vertical distance between the support plate 104 and the top plate 101 is d, and d is not less than 1/5H and not more than 1/4H. The moment of inertia of the cross section of the support plate 104 to the x-axis according to the parallel axis shift theorem is:
IX＝IXC+a2A
wherein, IXCThe moment of inertia of the support plate cross section centering axis (the centering axis is the middle line of the beam body perpendicular to the height direction of the beam body), and a is the vertical distance from the support plate cross section centering axis to the centering axis.
The smaller d is, the larger a is, the larger the moment of inertia of the cross section of the support plate 104 with respect to the x-axis is, and the larger the moment of inertia of the support beam as a whole is, so that the bending resistance of the support beam is improved and the support beam is not easily bent and deformed. The support plate 104 is located a distance away from the centerline of the beam body and is located closer to the top plate 101 to increase the bending resistance of the support beam. If the support plate 104 is disposed proximate to the top plate 101, the support beam is similar to a rectangular frame, which is easily deformed, resulting in poor integrity and easy deformation of the support beam. Therefore, the support plate 104 is disposed at the position 1/5H-1/4H away from the top plate 101 in consideration of the deformation and bending resistance of the support beam, thereby improving the bending resistance of the support beam and ensuring that the support beam is not easily deformed.

The support beam of the structure can prevent the edge part of the beam body from twisting by arranging the support plate 104 between the two side plates; meanwhile, the support plate 104 is supported in the beam body, so that when the span of the support beam is large, the overall strength and rigidity of the demister support beam can be effectively improved under the condition that the beam section is not increased or even reduced, and the demister support beam can stably support the demister module; and the beam cross-sectional dimension is little, and the beam width can be narrower, and the space that a supporting beam took up at 3 tops of desulfurizing tower reduces, the mass transfer area increase of defogging passageway, the circulation resistance of flue gas at defroster and desulfurizing tower system reduces, and the defroster removes dust and/or defogging efficiency improves. The cross section of the beam is small, the anticorrosive material required to be coated on the supporting beam is correspondingly reduced, and the anticorrosive cost is saved.
