Description

Technical Field

[0001] This utility model belongs to the field of flue gas desulfurization technology, specifically relating to an absorption tower bottom plate support structure assembly. Background Technology

[0002] In heavy industries such as coal-fired power plants, metallurgy, and chemical engineering, desulfurization towers are the core equipment of flue gas purification systems, and their structural reliability directly affects the operational efficiency of the entire environmental protection system. The support structure of the tower's base plate serves as the load-bearing foundation of the entire device, bearing the combined stresses of the tower's own weight, filling materials, liquid loads, and seismic and wind loads. Its design rationality directly impacts the safe operating cycle of the equipment. The currently widely used welded support system of steel profiles and embedded plates has revealed multi-dimensional technical defects in practical engineering applications, becoming a key bottleneck restricting the stable operation of desulfurization systems.

[0003] Traditional desulfurization tower base plate support structures use direct welding of structural steel to the base plate and embedded plates. This construction requires high precision, and during construction, factors such as concrete shrinkage deformation, formwork positioning errors, and uneven foundation settlement can easily lead to foundation defects, causing deformation of the steel structure. Rigid welded joints are prone to stress concentration under long-term dynamic loads, causing deformation of the steel structure. The deformation of the steel structure affects the flatness and service life of the base plate. The chain reaction caused by structural defects also seriously affects the desulfurization efficiency, resulting in a significant extension of the desulfurization construction period.

[0007] Support plate, connected to the base surface;

[0008] The support beam assembly has multiple main beams distributed along a first horizontal direction and multiple secondary beams distributed along a second horizontal direction. The two ends of each secondary beam are connected to two adjacent main beams. The first horizontal direction and the second horizontal direction are perpendicular to each other.

The side wall of the main beam has a bolt hole. The adjusting component passes through the oblong hole and is screwed into the bolt hole, thus cooperating with the main beam to clamp the first upright plate.

[0017] In one possible implementation, both the main beam and the secondary beam are angle steel beams, with the horizontal side of the main beam and the horizontal side of the secondary beam respectively abutting against the base plate, and the columns respectively connected to the vertical side of the corresponding main beam.

The columns and foundation surface are rigidly connected, and the columns and main beams are rigidly connected. The overall structure has high strength, is not easy to deform, and extends its service life. Attached Figure Description

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0037] It should be noted that the terms "length," "width," "height," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "head," and "tail," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model.

[0041] Please refer to the following: Figures 1 to 4The present invention provides a description of the absorption tower bottom plate support structure assembly. The absorption tower bottom plate support structure assembly supports the bottom plate of the absorption tower and includes a support plate 1, a support beam assembly 2, and multiple columns 3. The support plate 1 is connected to the foundation surface; the support beam assembly 2 has multiple main beams 21 distributed along a first horizontal direction and multiple secondary beams 22 distributed along a second horizontal direction, with each end of a secondary beam 22 connected to two adjacent main beams 21, and the first and second horizontal directions being perpendicular to each other; the main beams 21 and secondary beams 22 intersect to form a grid structure, with the top surfaces of the main beams 21 and secondary beams 22 respectively abutting against the bottom plate; the multiple columns 3 are evenly distributed on the upper surface of the support plate 1, and the top of each column 3 is connected to a main beam 21.

[0042] It should be noted that the foundation surface is a civil engineering foundation located at the bottom of the absorption tower. The foundation surface is manually smoothed and is a horizontal surface, thus making the surface of the support plate 1 parallel to the horizontal direction.

[0043] It should be noted that the flatness of multiple mesh holes is the same, precisely ensuring that the flatness of each part of the mesh hole structure is the same, so that the base plate can be supported horizontally and stably.

[0044] It should be noted that, Figure 1 The solid arrows in the diagram represent the first horizontal direction, and the dashed arrows represent the second horizontal direction.

[0045] Compared with the prior art, the absorption tower bottom plate support structure assembly provided in this embodiment has a support structure set under the floor of the absorption tower. The main beam 21 and the secondary beam 22 are supported by the columns 3 and form a grid structure to stably abut against the bottom plate. The columns 3 are fixed to the foundation surface and provide stable support for the main beam 21 and the secondary beam 22. The flatness of each grid hole of the main beam 21 and the secondary beam 22 can be controlled individually, which improves the flatness accuracy of the grid structure formed by the main beam 21 and the secondary beam 22, thereby ensuring the flatness of the bottom plate, ensuring the normal operation of the bottom plate, and thus ensuring the desulfurization efficiency. The columns 3 are rigidly connected to the foundation surface and the main beam 21. The overall structure has high strength, is not easy to deform, and extends its service life.

[0046] In some embodiments, see Figure 2 The support plate 1 has a connection hole; the absorption tower bottom plate support structure assembly also includes a fastener 4, which passes through the connection hole and connects to the foundation surface. The connection hole allows the fastener 4 to cooperate with the foundation surface to clamp and fix the support plate 1, thereby ensuring that the support plate 1 is always stably connected to the foundation surface. The support plate 1 will not shift during operation, ensuring stable support of the bottom plate and extending the service life of the bottom plate.

[0047] In some embodiments, the fastener 4 includes an expansion bolt and an expansion tube. An expansion hole is provided on the base surface, and the expansion tube passes through the connection hole and is inserted into the expansion hole. The expansion bolt squeezes the expansion tube from the inside, causing the expansion tube and the expansion hole to abut against each other, thereby restricting the vertical displacement of the expansion tube and thus keeping the connecting plate 1 stably fixed relative to the base surface.

[0048] In practice, the lower end of the expansion bolt has an expansion head, and the expansion tube is inserted into the expansion hole together with the expansion bolt. When the nut is tightened, the expansion bolt is subjected to an outward pulling force, and the expansion head or conical structure at its tail pushes the expansion tube to expand outward. The expansion tube expands due to compression deformation. The expansion tube fits tightly against the hole wall of the expansion hole, forming a gripping force similar to a "claw". Through friction and mechanical interlocking, the bolt is firmly fixed inside the substrate.

[0049] In some embodiments, the bottom end of the column 3 is welded to the support plate 1. The welding arrangement ensures a high connection strength between the column 3 and the support plate 1, preventing the column 3 from easily deforming or tilting under pressure, thus improving the stability and service life of the support structure and ensuring the normal operation of the absorption tower bottom plate.

[0050] In some embodiments, multiple columns 3 are distributed in a staggered pattern above the support plate 1 and are connected to the corresponding main beams 21. The staggered distribution design can evenly distribute the pressure from the base plate, preventing stress concentration. The columns 3 bear the pressure evenly, ensuring the stable support of the base plate for the main beams 21 and secondary beams 22.

[0051] In practice, the multiple columns 3 can also be distributed in a diamond shape or a ring shape, as long as they can distribute the pressure and stably support the main beam 21.

[0052] In some embodiments, see Figure 2 and Figure 3 The column 3 includes a first vertical plate 31 and a second vertical plate 32 that are perpendicular to each other. The first vertical plate 31 is fitted against the side wall of the main beam 21, and the second vertical plate 32 is perpendicular to the side wall of the main beam 21. The first vertical plate 31 has an adjustment hole 311 running vertically through it. The absorption tower bottom plate support structure assembly also includes an adjustment component 5, which passes through the adjustment hole 311 and is fastened to the main beam 21. The column 3 is made of angle steel, which is widely available, low in cost, and has good economic benefits, reducing manufacturing costs. The first vertical plate 31 and the main beam 21 are fitted together, with a large contact area, which reduces the difficulty of connecting the column 3 and the main beam 21 and improves the connection strength. The adjustment hole 311 facilitates the connection between the column 3 and the main beam 21. The adjustment component 5, by connecting to the main beam 21, stably connects the column 3 and the main beam 21, improving the speed and convenience of assembly and disassembly.

[0053] In some embodiments, see Figure 3The adjusting hole 311 is an elongated oval hole, with its major axis parallel to the vertical direction. The adjusting component 5 is an adjusting bolt. Bolt holes are provided on the side wall of the main beam 21. The adjusting component 5 passes through the elongated oval hole and is screwed into the bolt holes, thus clamping the first upright plate 31 in conjunction with the main beam 21. The elongated oval hole 311 allows the adjusting component 5 to select a contact position with the adjusting hole 311 when connected to the main beam 21. By contacting different areas at different heights with the adjusting hole 311, the connection height between the main beam 21 and the upright 3 can be adjusted, thereby adjusting the height and levelness of the main beam 21 and improving installation flexibility. After installation, the flatness and height of the main beam 21 can be adjusted by adjusting the position of the adjusting component 5 and the adjusting hole 311, simplifying the installation steps and improving installation efficiency.

[0054] In practice, the adjustment hole 311 can also be an oblong hole.

[0055] In some embodiments, see Figure 4 Both the main beam 21 and the secondary beam 22 are angle steel beams. The horizontal sides of the main beam 21 and the secondary beam 22 respectively abut against the base plate, and the columns 3 are respectively connected to the vertical sides of the corresponding main beam 21. Angle steel is widely available and inexpensive. By having the horizontal surfaces of the main beam 21 and the secondary beam 22 fit against the base plate, the pressure from the base plate is distributed. The angle steel has a small self-weight, which can reduce the self-weight of the grid structure of the main beam 21 and the secondary beam 22, improve the convenience of installation, and save labor intensity.

[0056] In specific implementation, the main beam 21 includes a first side plate and a second side plate that are perpendicular to each other, and the secondary beam 22 includes a third side plate and a fourth side plate that are perpendicular to each other. The first side plate and the third side plate are both horizontal plates and are respectively attached to the bottom surface of the base plate. The second side plate and the fourth side plate are both vertical plates. The second side plate is connected to the column 3.

[0057] In some embodiments, see Figure 4 The supporting beam assembly 2 also includes a connecting plate 23. One end of the connecting plate 23 is connected to one side of the vertical side of the main beam 21, and the other end of the connecting plate 23 is connected to the vertical side of the secondary beam 22. The other side of the vertical side of the main beam 21 is connected to the end face of the secondary beam 22. The connecting plate 23 increases the contact area and provides a connection position. When both the main beam 21 and the secondary beam 22 are angle steel, the connecting plate 23 increases the connection area, ensuring that the connection area can support the overall structural strength, thereby improving the bonding strength between the main beam 21 and the secondary beam 22. The setting of the connecting plate 23 reduces the construction difficulty and facilitates subsequent adjustment of the flatness of the local grid holes. The straightness of the main beam 21 and the flatness of the frame structure composed of the main beam 21 and the secondary beam 22 directly determine the flatness of the desulfurization tower bottom plate, thereby ensuring the stability of the entire supporting structure.

[0058] In some embodiments, see Figure 1The absorption tower bottom plate support structure assembly also includes a ring beam 6, which surrounds the outer perimeter of the grid structure. The inner ring of the ring beam 6 connects to the corresponding main beam 21 and secondary beam 22, while the outer ring connects to the inner ring surface of the absorption tower. The ring beam 6 connects the main beam 21 and secondary beam 22 around their outer perimeter, improving the overall structural consistency and stability. The ring beam 6 also reduces the concentrated stress at this connection point on the desulfurization tower bottom plate, thereby increasing the stiffness and stability of the entire bottom plate support structure.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
