Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of desulfurization and denitration, and in particular to a magnetic suction plugging device, and on this basis, also relates to a desulfurization and denitration system. Background Art
[0002] Thermal power plants usually generate electricity by burning materials, such as coal. However, the burning of coal produces a large amount of flue gas containing sulfur and nitrate. Therefore, at present, thermal power plants generally have desulfurization and denitrification systems to desulfurize and denitrify the flue gas generated during the power generation process of thermal power plants so that the flue gas meets the emission requirements. However, during the operation of the various equipment in the desulfurization and denitrification system, such as desulfurization towers and flue gas pipelines, due to equipment aging, medium corrosion, improper operation and other reasons, the equipment may leak, which in turn leads to a decrease in the desulfurization and denitrification efficiency. At the same time, the leakage of flue gas and chemical media in the equipment will also cause environmental pollution.
[0003] In addition, since the sulfur- and nitrate-containing flue gas and the chemical media contained in the desulfurization and denitrification equipment are corrosive, an anti-corrosion layer is generally set in the desulfurization and denitrification equipment. The anti-corrosion layer is flammable and explosive. If hot work is used, such as welding to plug leaks, it is very easy to cause explosions and serious safety accidents. Moreover, the continuous and uninterrupted operation of thermal power plants makes it impossible for desulfurization and denitrification equipment to be shut down for maintenance. At present, for the plugging operation of desulfurization and denitrification equipment, wooden sticks, cotton cloth, etc. are usually temporarily used to block the leakage points, but the plugging effect of this plugging method is poor, and there is still leakage at the leakage point. At the same time, the desulfurization and denitrification equipment contains chemical media, water and other liquids, so when the plugging glue is used to plug the leakage point, the plugging effect is not good due to liquid seepage. Utility Model Content
[0004] The utility model aims to overcome the problem that the leakage points of desulfurization and denitration equipment in the prior art cannot be completely blocked, and provides a magnetic leakage blocking device and a desulfurization and denitration system. The magnetic leakage blocking device has the advantages of firm blocking and not easy to leak.
[0005] In order to achieve the above-mentioned purpose, the first aspect of the utility model provides a magnetic leak-plugging device, comprising: a leak-plugging plate for covering the leakage area, the area of the leak-plugging plate being not less than the area of the leakage area; a fixed rod arranged on the side of the leak-plugging plate away from the leakage area; and a magnet arranged on the outside of the leak-plugging plate, the magnet being connected to the end of the fixed rod away from the leak-plugging plate, and the magnet being arranged to apply an extrusion force to the fixed rod toward the direction close to the leak-plugging plate.
[0006] Through the above technical solution, the plugging plate covers the leakage area, and the area of the plugging plate is not less than the area of the leakage area. When the plugging plate is subjected to an extrusion force in the direction close to the leakage area, the plugging plate can completely block the leakage area, thereby realizing the plugging operation without stopping the fire and the machine, and the plugging is firm and there is no leakage. In addition, the magnet is arranged on the outside of the plugging plate. Since the desulfurization and denitration equipment is usually made of a magnetic metal material, such as steel, the magnet can be adsorbed on the desulfurization and denitration equipment. The fixed rod is arranged on the side of the plugging plate away from the leakage area of the desulfurization and denitration equipment, and one end away from the plugging plate is connected to the magnet, and the other end can be fixed on the plugging plate or extended across the plugging plate to be connected to another magnet. In this way, the fixed rod is fixed on the side of the plugging plate away from the leakage area of the desulfurization and denitration equipment. By setting the height of the connection position of the fixed rod and the magnet from the desulfurization and denitration equipment, the fixed rod fits the plugging plate and further approaches the plugging plate, thereby applying an extrusion force in the direction close to the leakage area to the plugging plate, and then the plugging plate blocks the leakage area. When the magnet is removed from the desulfurization and denitrification equipment, the squeezing force can be eliminated and the disassembly of the magnetic leakage plugging device can be completed. Therefore, the magnetic leakage plugging device provided by the utility model also has the beneficial effects of being easy to assemble, disassemble and carry.

[0028] The magnetic plugging device provided by the utility model is adsorbed on the outer area of the plugging plate 3 of the desulfurization and denitration equipment by the magnet 6.

Since the plugging plate 3 covers the leakage area 1, and the area of the plugging plate 3 is not less than the area of the leakage area 1, when the extrusion force toward the leakage area is applied to the plugging plate, the plugging plate can completely block the leakage area, thereby realizing the plugging operation without stopping the fire and the machine, and the plugging is firm and there is no leakage.

[0029] Optionally, the shape of the plugging plate 3 can be any shape that matches the shape of the leakage area 1. For example, the shape of the plugging plate 3 is circular or rhombus-shaped. Alternatively, in some embodiments, the shape of the plugging plate 3 is square. In addition, the plugging plate 3 can be a flat plate or an arc-shaped shape, which is adjusted according to the shape of the actual desulfurization and denitrification equipment. Optionally, the material of the plugging plate 3 can be a metal material, such as iron, steel, etc., to ensure the strength of the plugging plate 3 and prevent damage due to the squeezing force of the fixing rod 4.

During installation, the fixing screw is threadedly matched with the fixing screw hole 5, and by tightening the fixing screw, a squeezing force is further applied to the plugging plate 3 toward the leakage area 1, thereby further improving the plugging effect of the plugging plate 3.
[0031] Optionally, refer to Figure 1 As shown, there are multiple fixing rods 4, and correspondingly, there are multiple magnets 6. In some embodiments, both ends of the fixing rod 4 are respectively connected to the corresponding magnets 6, and multiple fixing rods 4 can be stacked in the area of the plugging plate 3. Alternatively, according to an embodiment of the magnetic plugging device of the utility model, the magnetic plugging device also includes a multi-directional connector, which has multiple connection ports, and the end of the fixing rod 4 away from the magnet 6 is connected to the multi-directional connector.
[0032] Optionally, the multi-directional connector is arranged facing the leakage area 1 .
[0033] Optionally, a plurality of fixing rods 4 are symmetrically arranged about the leakage area 1 , so as to further improve the plugging effect of the plugging plate 3 .
[0034] According to an implementation of the magnetic suction plugging device of the utility model, referring to Figure 1 and Figure 2 As shown, the plugging plate 3 is square, the number of fixing rods 4 is 4, the multi-directional connector is a cross-shaped connector 9, the cross-shaped connector 9 is arranged at the center of the plugging plate 3 and has 4 connectors, the 4 fixing rods 4 are arranged in the vertical direction and the horizontal direction respectively, and the two ends are respectively connected to the corresponding magnets 6 and connectors, and the fixing top screw holes 5 on the fixing rods 4 can be arranged corresponding to the outer edge of the plugging plate 3. Of course, multiple fixing top screw holes 5 can be arranged on the fixing rod 4, and the multiple fixing top screw holes 5 are correspondingly arranged in the coverage area of the plugging plate 3.
[0035] Optionally, refer to Figure 1 and Figure 4As shown, an inner thread hole is provided on one side of the magnet 6 close to the plugging plate 3, and the end of the fixing rod 4 away from the plugging plate 3 can be threadedly connected to the inner thread hole. Or in some embodiments, a threaded hole is provided on the top of the magnet 6, and the magnetic plugging device of the utility model further includes a connecting elbow 8 whose two ends are respectively connected to the end of the fixing rod 4 away from the plugging plate 3 and the threaded hole of the magnet 6, so as to facilitate the installation and removal of the fixing rod 4.
[0036] Furthermore, the magnetic plugging device of the utility model further comprises a connecting rod whose two ends are respectively connected to the end of the connecting elbow 8 away from the fixing rod 4 and the threaded hole of the magnet 6.

[0039] Further, refer to Figure 1 As shown, the magnet 6 includes a disassembly screw hole 7 for installing a disassembly screw. Since the magnet 6 is firmly adsorbed on the desulfurization and denitration equipment, it is not easy to directly disassemble the magnet 6 from the desulfurization and denitration equipment. By installing a disassembly screw in the disassembly screw hole 7 of the magnet 6, when the disassembly screw is tightened, the disassembly screw applies a force to the magnet 6 away from the desulfurization and denitration equipment, so that the magnet 6 can be smoothly disassembled from the desulfurization and denitration equipment.
