Description

Technical Field

[0001] The utility model relates to the technical field of wet flue gas desulfurization, in particular to a support beam protection device. Background Art

[0002] Currently, the most widely used flue gas desulfurization process in large thermal power plants in my country is limestone-gypsum wet flue gas desulfurization. In this process, the sulfur dioxide absorption system is the core of the entire desulfurization process, consisting primarily of an absorption tower, a slurry circulation pump, and an oxidation blower. The absorption tower is a countercurrent spray structure, with a slurry pool at the bottom, a spray scrubbing zone in the middle, and a demister at the top. The spray scrubbing zone typically has multiple spray layers, typically made of FRP. The support beams are typically made of carbon steel, with glass flakes applied to the exterior for corrosion protection. Because the support beams are subject to slurry and other impacts, the falling glass flakes can cause rapid corrosion, potentially leading to serious safety hazards such as beam fracture. The current conventional solution involves coating the support beams with glass flakes for corrosion protection and then encasing them with PP sheets, or directly encasing the entire support beam with corrosion-resistant stainless steel. While using PP sheets to protect the support beams is economical, the quality of the PP sheet's hot-melt welding is significantly affected by the quality of the work. In many cases, PP sheets have fallen into the absorber slurry pool during operation, causing malfunctions in the absorber's side-entry agitator. Using corrosion-resistant 2205 duplex stainless steel to completely clad the support beams is expensive and significantly impacts project costs.

[0003] The Chinese utility model patent with publication number CN208032307U discloses a support beam for the spray layer of a desulfurization absorption tower, which includes an I-beam and two square steels. The characteristic is that the two square steels are symmetrically arranged in the receiving cavities on the left and right sides of the I-beam, and the square steels and the wing plates of the I-beam are fixed by bolts. The outer side of the square steel is wrapped with a fiberglass layer, an anti-cracking layer, a polyurethane elastomer buffer layer and a polypropylene layer from the inside to the outside. At least one wire threading hole is opened on the web of the I-beam and the square steel, and a reinforcement structure is arranged on the wire threading hole.

[0004] The above-mentioned support beam has high rigidity and good local and overall stability, which enhances the load-bearing capacity and bending and torsional strength of the support beam and has good resistance to force. However, it uses two square steels symmetrically arranged in the receiving cavity on the left and right sides of the I-beam. The square steel and the wing plates of the I-beam are fixed by bolts. The outer side of the square steel is wrapped with a fiberglass layer, an anti-cracking layer, a polyurethane elastomer buffer layer and a polypropylene layer from the inside to the outside, resulting in a complex overall structure, inconvenient maintenance, and high construction cost.

[0026] Example 1:

[0027] like Figure 1 、 Figure 2 and Figure 3As shown, the present embodiment provides a support beam protection device, which includes a support beam 1, glass flakes 2, a protection component, a pipe clamp 3, a diversion component 4 and a monitoring component 5. The surface of the support beam 1 is coated with glass flakes 2. The protection component is wrapped around the support beam 1 and fixed by the pipe clamp 3. The top of the pipe clamp 3 is provided with a diversion component 4. The monitoring component 5 is installed in the support beam 1. The monitoring component 5 is used to monitor the humidity and vibration of the support beam 1. In actual use, the support beam 1 is used to provide support and protection for the flue gas wet desulfurization spray layer. The glass flakes 2 are used to provide anti-corrosion support for the support beam 1 and improve the corrosion resistance of the support beam 1. The protection component is used to provide protection for the support beam 1 and isolate the support beam 1 from direct contact with the slurry. The pipe clamp 3 is used to fix the protection component and improve the stability and reliability of the protection component. The diversion component 4 is used to receive the scouring of the slurry and divert the slurry to reduce the accumulation of the slurry. The monitoring component 5 is used to monitor the vibration of the support beam 1 and monitor the vibration of the support beam 1. The internal humidity conditions are monitored, and the monitoring data is transmitted to the background terminal after analysis and processing for real-time viewing by the staff. It is necessary to first coat the surface of the support beam 1 with glass flakes 2, and then wrap the protection component around the support beam 1. The protection component wraps the support beam 1 as a whole, and then fix the pipe clamp 3 on the protection component. Finally, the monitoring component 5 is installed into the support beam 1. In order to facilitate the maintenance of the monitoring component 5, inspection ports can be opened on the support beam 1 and the protection component corresponding to the position of the monitoring component 5, and a PTFE support oil seal can be set.

[0028] In this embodiment, the protective assembly includes a plurality of protective plates 6, which are fixed by heat-melt welding. In actual use, the protective plates 6 are heat-melt welded to form a protective assembly with a rectangular cross-section. The protective plates 6 are first wrapped around the support beam 1 and then heat-melt fixed. The protective plates 6 can be made of PP plates, or plastic plates or rubber plates with good corrosion resistance.

[0029] In this embodiment, the number of the protective plates 6 is 4. In actual use, the 4 protective plates 6 are welded by heat-melting to form a protective assembly with a rectangular cross-section. The protective plates 6 are first wrapped around the support beam 1 and then fixed by heat-melting.

[0030] In this embodiment, the pipe clamp 3 includes a first pipe clamp 31, a second pipe clamp 32, a bolt 33 and a nut 34. The first pipe clamp 31 and the second pipe clamp 32 are sleeved on the protective plate 6 and are threadedly fixed by the bolt 33 and the nut 34. In actual use, the first pipe clamp 31 and the second pipe clamp 32 are arranged to match the shape formed by the hot-melt welding of the protective plate 6. The first pipe clamp 31 and the second pipe clamp 32 are fixed to the protective plate 6 by the bolt 33 and the nut 34, so as to enhance the stability and reliability of the protective plate 6 and prevent the protective plate 6 from shifting during use and being damaged and falling onto the absorption tower side-entry agitator, causing its operation failure. The first pipe clamp 31, the second pipe clamp 32, the bolt 33 and the nut 34 are all made of 2205 duplex stainless steel or other corrosion-resistant and wear-resistant materials.

[0031] In this embodiment, the deflector assembly 4 includes a fixing clamp 41 and a deflector plate 42. The fixing clamp 41 and the deflector plate 42 are fixedly connected, and the fixing clamp 41 is clamped to the pipe clamp 3. In actual use, the fixing clamp 41 is used to clamp the deflector plate 42 to the pipe clamp 3 for fixation. The deflector plate 42 is shaped to be high in the middle and low on both sides. When the slurry drips onto the deflector plate 42, it automatically drips to the sides under the action of gravity, reducing the accumulation of slurry on the support beam 1 and cushioning the impact of the slurry on the support beam 1. The fixing clamp 41 and the deflector plate 42 can be made of PP material or a plastic plate or rubber plate with good corrosion resistance.

[0032] In this embodiment, the guide plate 42 is filled with an elastic buffer layer. In actual use, the elastic buffer layer is made of an elastic buffer material, such as sponge, etc. The elastic buffer layer can buffer the impact of the slurry on the support beam 1, provide buffering support for the support beam 1, and improve the service life of the support beam 1.

[0033] Example 2:

[0034] like Figure 1 As shown, based on the first embodiment, the monitoring component 5 includes a humidity sensor 51, a vibration sensor 52, and a controller 53, and the humidity sensor 51 and the vibration sensor 52 are both electrically connected to the controller 53. In actual use, the humidity sensor 51 is used to monitor the humidity inside the support beam 1, and the vibration sensor 52 is used to monitor the vibration of the support beam 1. The monitored data is transmitted to the controller 53 for analysis and processing. The data analyzed and processed by the controller 53 is then transmitted to the back-end terminal, allowing staff to obtain real-time information on the working status of the support beam 1.

[0035] In this embodiment, the controller 53 is an MSP430 controller. In actual use, the MSP430 controller has the advantages of strong scalability and low power consumption. It can analyze and process the data monitored by the humidity sensor 51 and the vibration sensor 52 through wiring, and then transmit the analyzed and processed data to the backend terminal. This is suitable for the long-term use of the support beam 1 and reduces energy consumption.

[0036] In this embodiment, the humidity sensor 51 is a SI7020-A20-IMR humidity sensor. In actual use, the SI7020-A20-IMR humidity sensor can be purchased directly and connected to the appropriate wiring to detect the humidity inside the support beam 1. When the support beam 1 is damaged, resulting in damage to its surface, the spray slurry from the wet flue gas desulfurization spray layer will enter the support beam 1, accelerating corrosion of the support beam 1. This allows staff to detect and intervene promptly through the backend terminal.

[0037] In this embodiment, the vibration sensor 52 is a BMA250 vibration sensor. In actual use, the BMA250 vibration sensor can be directly purchased and connected to the appropriate wiring to achieve vibration monitoring of the support beam 1. If the spray system of the wet flue gas desulfurization spray layer malfunctions, causing the support beam 1 to be excessively slurried and possibly damaged by uneven force, the staff can promptly detect and intervene through the back-end terminal.

[0038] All technical features in this embodiment can be freely combined according to actual needs. The above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
