Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a support device for the packing of a sulfuric acid absorption tower. Background Technology

[0002] A sulfuric acid absorption tower is a common chemical reaction device mainly used to remove sulfides from gases, reducing the sulfide content to an acceptable level. Its working principle involves a chemical reaction between sulfuric acid and sulfides in the gas, converting the sulfides into sulfates, thereby achieving desulfurization of the gas. The internal packing support system plays a crucial role in supporting the packing material.

[0003] However, existing sulfuric acid absorption tower packing support devices have significant drawbacks. Most traditional support devices are one-piece structures, requiring extensive on-site welding inside the tower during installation, which is difficult to implement. Furthermore, if the support device suffers partial damage or the packing needs replacement or repair, the one-piece structure is difficult to disassemble quickly, often requiring substantial manpower, resources, and time, severely impacting production efficiency and increasing production costs for enterprises.

[0004] Therefore, a support device for the packing of a sulfuric acid absorption tower is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a support device for the packing of a sulfuric acid absorption tower in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A support device for the packing of a sulfuric acid absorption tower includes a fixed base and a support frame module. The surface of the fixed base has a through-hole for assembly. An overlapping frame is fixedly connected to the inner wall of the assembly hole. The surface of the overlapping frame is provided with a connecting component for installing the support frame module. The top surface of the support frame module has a positioning hole. The surface of the support frame module has a slot. A grid module is movably inserted into the inner wall of the slot.

[0008] Furthermore, the connecting assembly includes a positioning screw, which is fixedly connected to the surface of the overlapping frame. A fastening nut is threaded onto the surface of the positioning screw, which is used to fasten the support frame module to the overlapping frame. Both the positioning screw and the fastening nut are made of corrosion-resistant alloy steel, and the surfaces of the positioning screw and the fastening nut are plated with a zinc layer.

[0009] Furthermore, the grid size of the grid module is designed according to the size of the filler, and the grid module is detachably installed in the slot inside the support frame module.

[0010] Furthermore, there are two positioning ports, and the two positioning ports are symmetrically distributed on the surface of the support frame module.

[0011] Furthermore, the corrosion-resistant metal material of the support frame module is stainless steel, and its surface has been passivated.

[0012] Furthermore, the corrosion-resistant grating plate of the grating module is formed by welding multiple cross bars, and the cross section of the bars is trapezoidal.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this invention, when a module of the support device is damaged or the filler needs repair, it is not necessary to dismantle the entire support device. Simply loosen the connecting components, remove the damaged or repaired module individually for replacement or repair, and then reinstall it. This method not only saves repair time but also reduces the impact on production and improves production efficiency.

[0015] 2. The modular design allows the support device to be prefabricated in the factory, with each module having uniform size and specifications, making quality control easy. During on-site installation, only the individual modular components need to be transported to the site and assembled using connecting components, reducing installation difficulty.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a support device for sulfuric acid absorption tower packing includes a fixed base 1 and a support frame module 5. The surface of the fixed base 1 has a through-hole 2, and an overlapping frame 3 is fixedly connected to the inner wall of the through-hole 2. The surface of the overlapping frame 3 is provided with connecting components 4 for installing the support frame module 5. The top surface of the support frame module 5 has a positioning opening 6, and the surface of the support frame module 5 has a slot 7. A grid module 8 is movably inserted into the inner wall of the slot 7. Specifically, the fixed base 1 serves as the foundation component of the entire support device, providing stable support. Its material is corrosion-resistant, such as specially treated carbon steel, to adapt to the highly corrosive environment inside the sulfuric acid absorption tower. The through-hole 2 on the surface of the fixed base 1 is designed according to actual installation requirements for the subsequent installation of components such as the support frame module 5. The overlapping frame 3 is made of stainless steel, possessing good corrosion resistance and structural strength. It provides a base platform for the installation of the support frame module 5, and its size is adapted to the support frame module 5 to achieve stable overlap. The support device for the sulfuric acid absorption tower packing has a fixed base 1 installed inside the sulfuric acid absorption tower. The fixed base 1 has an assembly port 2, through which an overlap frame 3 is connected, allowing the support frame module 5 and the grid module 8 to be assembled and installed on the overlap frame 3. The connecting component 4 allows the support frame module 5 to be positioned and installed on the overlap frame 3. The positioning port 6 on the support frame module 5 allows the grid module 8 to be inserted into the slot 7, with the height of the grid module 8 lower than the height of the slot 7. This prevents solution from accumulating on the fixed base 1 and the support frame module 5. The positioning port 6, in conjunction with the connecting component 4, allows the support frame module 5 to be positioned and installed on the overlap frame 3. During use, if a support frame module 5 or grid module 8 is found to be damaged, or if the packing needs repair, simply loosen the connecting component 4 and disassemble the damaged support frame module 5 or grid module 8 for replacement or repair.

[0026] like Figure 1 , Figure 2As shown, the connecting component 4 includes a positioning screw 401. The positioning screw 401 is fixedly connected to the surface of the overlapping frame 3, and a fastening nut 402 is threaded onto the surface of the positioning screw 401. The fastening nut 402 is used to fasten the support frame module 5 to the overlapping frame 3. Both the positioning screw 401 and the fastening nut 402 are made of corrosion-resistant alloy steel, and their surfaces are plated with a zinc layer. Specifically, the connecting component 4 is used in conjunction with the positioning port 6 to position and install the support frame module 5 on the overlapping frame 3. The positioning screws 401 are fixedly connected to the surface of the overlapping frame 3, and their number is reasonably set according to the size and weight of the support frame module 5, and they are evenly distributed on the overlapping frame 3. Both the positioning screws 401 and the fastening nut 402 are made of corrosion-resistant alloy steel, and their surfaces are plated with a zinc layer or other anti-corrosion coating to prevent corrosion inside the sulfuric acid absorption tower. During installation, a positioning port 6 is provided on the support frame module 5 at the position corresponding to the positioning screw 401. By tightening the fastening nut 402 onto the positioning screw 401, the support frame module 5 is fastened to the overlapping frame 3.

[0027] like Figure 1 , Figure 3 As shown, the mesh size of the grid module 8 is designed according to the size of the packing material. The grid module 8 is detachably installed in the slot 7 inside the support frame module 5. Specifically, a suitable mesh size allows the packing material to be placed evenly and stably on the grid module 8, preventing the packing material from falling off due to an overly large mesh or obstructing normal filling due to an overly small mesh. This ensures effective support of the packing material by the support device, allowing gas and liquid to pass through the packing layer more smoothly. It also prevents poor gas-liquid flow caused by an unreasonable mesh design, which would affect the mass and heat transfer efficiency in the sulfuric acid absorption tower and help improve the working performance of the absorption tower. When the grid module 8 becomes clogged or corroded, it can be easily and quickly disassembled for cleaning, repair, or replacement without major changes to the entire support device, saving maintenance time and labor costs.

[0028] like Figure 4 As shown, there are two positioning ports 6, and the two positioning ports 6 are symmetrically distributed on the surface of the support frame module 5. Specifically, the holes of the positioning ports 6 can also be trapezoidal, in which case the positioning screw 401 can pass through the positioning port 6 more conveniently, and the fastening nut 402 can be tightened to fix the support frame module 5 to the overlapping frame 3. The two symmetrically distributed positioning ports 6 can cooperate with the corresponding positioning structures on the mounting components to position the support frame module 5 from two directions, which can effectively prevent the module from shifting or twisting during installation, ensuring that the support frame module 5 is accurately installed in the predetermined position, and guaranteeing the accuracy and precision of the entire support device installation.

[0029] like Figure 3As shown, the corrosion-resistant metal material of the support frame module 5 is stainless steel, and its surface has undergone passivation treatment. Specifically, stainless steel itself has excellent corrosion resistance and can resist the erosion of highly corrosive media such as sulfuric acid in the sulfuric acid absorption tower. This effectively prevents structural damage and reduced strength of the support frame module 5 due to corrosion, extending the service life of the support device. The passivation treatment forms a dense and stable oxide film on the surface of the stainless steel, further improving its corrosion resistance. Especially in a highly corrosive environment such as sulfuric acid, it can significantly slow down the corrosion rate of the metal and protect the internal metal of the support frame module 5 from corrosion.

[0030] like Figure 3 As shown, the corrosion-resistant grating plate of grating module 8 is composed of multiple cross-welded bars with trapezoidal cross-sections. Specifically, the cross-welded structure gives the grating plate good load-bearing capacity in all directions, effectively withstanding the weight of the packing material and the impact force generated by gas-liquid flow. Compared with conventional shapes such as rectangles, the trapezoidal cross-section increases the moment of inertia and section modulus of the bars with the same material usage, improving its bending resistance and reducing the likelihood of deformation or breakage, thus ensuring the long-term stable operation of the support device. The cross-welded bars form a stable grid structure, providing a uniform and stable support surface for the packing material. The trapezoidal cross-section bars, wider at the top and narrower at the bottom, lower the overall center of gravity of the grating plate, resulting in better stability after the packing material is placed. The trapezoidal cross-section also prevents impurities from accumulating on the bars, reducing the possibility of blockage. Even if a small amount of impurities adhere, they are more easily removed during gas-liquid flushing or periodic cleaning.

[0031] In summary: During installation, the fixed base 1 is installed inside the absorption tower. A suitable number of support frame modules 5 are selected, and these modules are positioned and installed using the connecting assembly 4. When installing the support frame modules 5, a positioning port 6 is provided on the surface of each module. The positioning port 6 is aligned with the positioning screw 401. The support frame module 5 is placed downwards, overlapping the overlapping frame 3. The fastening nut 402 is then tightened to fix the support frame module 5 to the overlapping frame 3. Similarly, the support frame modules 5 are assembled sequentially. Then, the grid module 8 is installed inside the slot 7 of the support frame module 5, completing the assembly of the support device. The packing material is then placed on the support device. During use, if a support frame module 5 is found to be damaged or the packing material needs repair, simply loosen the fastening nut 402 and remove the damaged support frame module 5 for replacement or repair. If the grid module 8 malfunctions, it can be directly pulled out for replacement. Both the support frame module 5 and the grid module 8 are made of corrosion-resistant metal materials, which can effectively resist the corrosion of sulfuric acid and extend the service life of the support device.
