Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection equipment, and in particular to a heating and desulphurization and denitrification system decolorization equipment. Background Art

[0002] In modern industrial production, particularly in the power, steel, and chemical industries, the combustion of fossil fuels produces large amounts of flue gas containing pollutants such as sulfur dioxide, nitrogen oxides, and dust. To reduce the environmental harm of these pollutants, desulfurization and denitrification processes are widely used in flue gas treatment systems. Although the pollutant content of flue gas after desulfurization and denitrification is significantly reduced, it often suffers from low temperature and high humidity. When discharged into the atmosphere, it easily forms a white smoke plume, which not only affects the visual landscape but can also cause a series of environmental problems.

[0003] The main purpose of the heating and white plume elimination equipment in the desulfurization and denitrification system is to heat the treated flue gas, reduce the supersaturation of water vapor in the flue gas, and thus eliminate the white plume phenomenon. Its core function is to transfer the heat of the heat medium to the low-temperature flue gas through heat exchange, increase the flue gas temperature, and make it difficult for the water vapor in the flue gas to condense into small water droplets, thereby avoiding the formation of white plumes that cause visual pollution to the environment. At the same time, appropriately increasing the flue gas temperature helps to increase the lifting height of chimney emissions, promote the diffusion of pollutants in the atmosphere, and reduce the concentration of pollutants in local areas, which is of great significance to improving regional air quality.

[0004] At present, the common heating and de-whitening equipment on the market is mainly composed of heat exchangers, heat medium supply systems, flue gas inlet and outlet pipes, and control systems. Heat exchangers are key components. Common types include tubular heat exchangers and plate heat exchangers. Tubular heat exchangers are generally composed of multiple parallel metal tubes. The flue gas flows inside the tubes, and the heat medium flows around the tube bundle outside the tubes, and heat transfer is achieved through the tube walls. The plate heat exchanger is composed of a series of parallel and corrugated metal plates stacked together. The heat medium and flue gas flow in reverse in the channels between adjacent plates for heat exchange.

[0005] However, in actual use, traditional tubular heat exchangers generally have large tube diameters and sparse arrangements, with a relatively small heat exchange area. The contact between the flue gas and the heat medium is not sufficient, the heat transfer is not efficient, and the flue gas flow rate in the tube is uneven, and dead zones are prone to occur, further reducing the heat exchange efficiency. Although the plate heat exchanger increases the heat exchange area to a certain extent, the flow channels between the plates are narrow and easily blocked by dust, impurities, etc. in the flue gas, resulting in poor circulation of the heat medium and flue gas, seriously affecting the heat exchange effect. In addition, the sealing performance of the plate heat exchanger is poor. During long-term operation, the heat medium or flue gas is prone to leakage, which not only reduces the heat exchange efficiency of the equipment, but also may cause safety hazards. Summary of the Invention

[0006] The present invention proposes a heating and descaling device for a desulfurization and denitrification system to solve the problem raised in the background technology that the heating and descaling device in the prior art has poor heat exchange efficiency when the flue gas emission fluctuates greatly or the flue gas after desulfurization and denitrification is heated for a long time.

A power assembly for driving the planetary power mechanism is installed on the upper transfer tube.

[0010] There are two heat medium gas delivery components, each of which corresponds to the heat medium cavity one by one and is connected to the heat medium cavity;

[0011] There are two smoke gas delivery components, each corresponding to the smoke cavity and connected to the smoke cavity;

[0015] The inner gear ring is rotatably mounted on the upper transfer tube or the lower transfer tube, and the inner gear ring is located between the two separation plates;

[0016] There are a plurality of planetary gears, each of which corresponds to the internally threaded tube. The planetary gears are arranged on the internally threaded tube and mesh with the internal gear ring.

[0017] The power shaft passes through and is rotatably disposed between the two separation plates;

[0018] The sun gear is arranged on the power shaft, is located between the plurality of planetary gears, and is meshed with the planetary gears.

[0019] Based on the above solution, the power assembly includes a central shaft and a power motor;

[0020] The central shaft is provided through the two power shafts and is used to drive the power shafts to rotate;

[0021] The power motor is installed on the upper transfer tube, and the output end of the power motor is connected to one end of the central shaft.

[0022] As a preferred technical solution of the present invention, the two separating plates close to one side of the corrugated outer tube are sealed and rotatably provided with cleaning rings, and cleaning rods are symmetrically arranged between the two inner gear rings. The cleaning rods are arranged through the cleaning rings, and a scraper plate in contact with the inner wall of the corrugated outer tube is provided on one side of each cleaning rod.

[0023] Based on the above scheme, one side of the lower transfer pipe is connected to a slag discharge pipe, a slag discharge valve is installed on the slag discharge pipe, the slag discharge pipe is connected to the flue gas cavity, and the slag discharge pipe is located above the separation plate and is used to remove impurities on the separation plate.

[0024] Further to the above solution, the central shaft is provided with spiral air guide vanes, and the spiral air guide vanes are located between the plurality of internally threaded tubes.

[0025] On the basis of the above solution, the heat medium gas transmission component includes a heat medium ring pipe and a heat medium gas supply pipe;

[0026] The heat medium ring pipe is connected to the heat medium cavity through a plurality of heat medium gas pipes arranged at equal angles;

[0027] There are multiple heat medium air supply pipes, and the heat medium air supply pipes are connected to the heat medium ring pipe. A heat medium valve is installed on each heat medium air supply pipe.

[0028] On the basis of the above solution, the flue gas transmission assembly includes a flue gas ring pipe and a flue gas delivery pipe;

[0029] The smoke ring pipe is connected to the smoke cavity through a plurality of smoke transmission pipes arranged at equal angles;

[0030] There are multiple smoke gas supply pipes, which are connected to the smoke ring pipe, and each smoke gas supply pipe is equipped with a smoke valve.

[0031] Further on the basis of the above solution, when the upper transfer pipe and the lower transfer pipe are docked, a docking pipe is connected between the heat medium air supply pipes or the flue gas air supply pipes corresponding one to one between the upper transfer pipe and the lower transfer pipe.

[0032] On the basis of the above scheme, the heat medium gas and the flue gas flow in opposite directions in the internal threaded pipe and the corrugated elbow respectively.

[0033] The beneficial effects of the present invention are:

[0034] 1. In the present invention, a planetary power mechanism is provided to separate the interiors of the upper and lower transfer tubes into a heat medium cavity and a flue gas cavity, so that the heat medium gas transmission assembly is connected to the heat medium cavity, and the flue gas transmission assembly is connected to the flue gas cavity. The heat medium gas delivery pipe in the heat medium gas transmission assembly is connected to the heat medium supply system, and the flue gas delivery pipe in the flue gas transmission assembly is connected to the flue gas after desulfurization and denitrification treatment, so that the heat medium gas and the flue gas flow in opposite directions in the internal threaded tube and the corrugated outer tube, respectively. This countercurrent heat exchange method greatly improves the heat exchange efficiency, can more fully utilize the heat of the heat medium gas to heat the flue gas, and effectively achieves the whitening effect. Compared with traditional downstream heat exchange, countercurrent heat exchange can achieve more efficient heat transfer under a smaller temperature difference, reducing energy waste.

[0035] 2. In the present invention, the internal threaded tube is passed through and rotatably arranged between the two planetary power mechanisms and is connected to the two heat medium cavities. When the power motor is started to drive the planetary power mechanism to move, the internal threaded tube is caused to rotate. When the internal threaded tube rotates, the special structure of the internal threaded tube can increase the disturbance of the heat medium gas flowing in the tube, and the boundary layer is destroyed, thereby enhancing the heat transfer process. Compared with ordinary smooth tubes, the internal threaded tube can significantly improve the heat transfer coefficient between the heat medium and the tube wall, further improving the heat exchange capacity of the entire equipment, and making the heating and de-whitening process more efficient.

[0036] 3. In the present invention, since flue gas contains acidic substances such as sulfur dioxide and nitrogen oxides, as well as impurities such as dust, the heat exchanger is extremely susceptible to corrosion and scaling during long-term operation. Cleaning rings are provided on two separating plates close to one side of the corrugated outer tube, both sealed and rotatable. Cleaning rods are symmetrically provided between the two inner gear rings, so that the cleaning rods are provided through the cleaning rings. Furthermore, a scraper plate is provided on one side of each cleaning rod, which contacts the inner wall of the corrugated outer tube. When the planetary power mechanism is in operation, the planetary gear is restricted by the inner threaded tube and can only rotate on its own. The planetary gear drives the inner gear ring to rotate, which in turn drives the cleaning rod to rotate, so that the scraper plate scrapes the inner wall of the corrugated outer tube, thereby timely removing impurities and dirt accumulated on the tube wall to prevent the heat exchange efficiency and the normal operation of the equipment from being affected.

[0037] 4. In the present invention, a slag discharge pipe is connected to one side of the lower transfer pipe, and a slag discharge valve is installed on the slag discharge pipe, so that the slag discharge pipe is connected to the flue gas cavity and is located above the separation plate. During the operation of the equipment, impurities scraped by the scraper plate can be discharged through the slag discharge pipe, avoiding the accumulation of impurities inside the equipment. The setting of the slag discharge valve can conveniently control the timing of slag discharge, ensure the cleanliness of the interior of the equipment, and also facilitate the centralized treatment of discharged impurities, reducing pollution to the environment.

[0038] 5. In the present invention, when used in desulfurization and denitrification systems of different scales, multiple groups of the heating and denitrification equipment can be selected, so that when the upper transfer pipe and the lower transfer pipe in each group of equipment are connected, a docking pipe is connected between the heat medium air supply pipe or the flue gas air supply pipe corresponding to each other between the upper transfer pipe and the lower transfer pipe, and the two adjacent central shafts are connected, and a power motor drives the multiple connected central shafts to rotate synchronously. This design not only makes the equipment more flexible during installation and use, but also allows different modules to be combined and docked according to actual needs, and facilitates the transportation, installation and subsequent maintenance and upgrading of the equipment. The setting of the docking pipe also facilitates the expansion of the equipment. Users can add or reduce modules according to actual needs to adapt to desulfurization and denitrification systems of different scales. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0050] like Figures 1 to 7 As shown, this embodiment proposes a temperature-raising and whitening removal device for a desulfurization and denitrification system, comprising a corrugated outer pipe 1, a heat medium gas transmission component, a flue gas gas transmission component and an internal threaded pipe 4.

[0051] Among them, one end of the corrugated outer tube 1 is connected to the upper transfer tube 2, and the other end is connected to the lower transfer tube 3. The upper transfer tube 2 and the lower transfer tube 3 can be docked. As shown in the figure, flange blind docking is the best choice for docking, which facilitates the disassembly of the upper transfer tube 2 and the lower transfer tube 3.

[0052] As mentioned above, planetary power mechanisms 001 are symmetrically arranged in the upper transfer tube 2 and the lower transfer tube 3. The planetary power mechanisms 001 divide the upper transfer tube 2 and the lower transfer tube 3 into a heat medium cavity and a flue gas cavity. The flue gas cavity is connected to one side of the corrugated outer tube 1. A power component 002 for driving the planetary power mechanism 001 to move is installed on the upper transfer tube 2.

[0053] like Figure 5As shown, the planetary power mechanism 001 includes two separating disks 5, an inner gear ring 6, planetary gears 7, a power shaft 8 and a sun gear 9. The separating disk 5 is sealed in the upper transfer tube 2 or the lower transfer tube 3. The inner threaded tube 4 passes through and is sealed and rotatably set on the two separating disks 5. The inner gear ring 6 is rotatably set on the upper transfer tube 2 or the lower transfer tube 3. The inner gear ring 6 is located between the two separating disks 5. There are several planetary gears 7, which correspond to the inner threaded tubes 4 one by one. The planetary gears 7 are arranged on the inner threaded tubes 4, and the planetary gears 7 are meshed with the inner gear ring 6. The power shaft 8 passes through and is rotatably set between the two separating disks 5. The sun gear 9 is arranged on the power shaft 8. The sun gear 9 is located between multiple planetary gears 7 and meshes with the planetary gears 7.

[0054] Among them, the power component 002 includes a central shaft 10 and a power motor 11. The central shaft 10 is set through the two power shafts 8 to drive the power shafts 8 to rotate. The power motor 11 is installed on the upper transfer tube 2, and the output end of the power motor 11 is connected to one end of the central shaft 10.

[0055] As mentioned above, there are a plurality of internal threaded tubes 4 , which penetrate and are rotatably arranged between the two planetary power mechanisms 001 , and are communicated with the two heat medium cavities.

[0056] As mentioned above, the flange blind plate is also provided with a docking through hole adapted to the central shaft rod 10 , and the central shaft rod 10 passes through and is sealed and rotatably arranged in the docking through hole so as to dock the two central shaft rods 10 .

[0057] Specifically, start the power motor 11, and the output end of the power motor 11 can drive the central shaft 10 to rotate, and the central shaft 10 drives the power shaft 8 to rotate, and the rotation of the power shaft 8 drives the sun gear 9 to rotate, and the sun gear 9 drives multiple planetary gears 7 meshing with it to rotate. Since the internal threaded tube 4 is rotatably arranged on the dividing disk, the planetary gear 7 is restricted by the internal threaded tube 4 to rotate, and the rotation of the planetary gear 7 drives the inner gear ring 6 to rotate. This structural design makes the power transmission direct and efficient, and the power motor 11 can stably provide power to the planetary power mechanism 001 to ensure the normal operation of the entire equipment. Moreover, the setting of the central shaft 10 ensures that the two power shafts 8 rotate synchronously, so that the planetary power mechanisms 001 in the upper transfer tube 2 and the lower transfer tube 3 can work in a coordinated manner, further improving the stability of the equipment operation.

[0058] It should be noted that the two separating plates 5 close to one side of the corrugated outer tube 1 are sealed and rotatably provided with cleaning rings 12, and cleaning rods 13 are symmetrically arranged between the two inner gear rings 6. The cleaning rods 13 are arranged through the cleaning rings 12, and a scraper plate 14 in contact with the inner wall of the corrugated outer tube 1 is provided on one side of each cleaning rod 13.

[0059] Specifically, since the flue gas contains acidic substances such as sulfur dioxide and nitrogen oxides, as well as impurities such as dust, the heat exchanger is extremely susceptible to corrosion and scaling during long-term operation. A cleaning ring 12 is sealed and rotatably provided on the two separating plates 5 close to one side of the corrugated outer tube 1, and a cleaning rod 13 is symmetrically provided between the two inner gear rings 6, so that the cleaning rod 13 is penetrated and provided on the cleaning ring 12, and a scraper plate 14 in contact with the inner wall of the corrugated outer tube 1 is provided on one side of each cleaning rod 13. When the planetary power mechanism 001 is running, the planetary gear 7 is restricted by the internal threaded tube 4 and can only rotate on its own. The planetary gear 7 drives the inner gear ring 6 to rotate, and the inner gear ring 6 drives the cleaning rod 13 to rotate, so that the scraper plate 14 scrapes the inner wall of the corrugated outer tube 1, and timely removes impurities and dirt accumulated on the tube wall to prevent affecting the heat exchange efficiency and the normal operation of the equipment.

[0060] As mentioned above, one side of the lower transfer pipe 3 is connected to a slag discharge pipe 15 , on which a slag discharge valve 16 is installed. The slag discharge pipe 15 is connected to the flue gas cavity. The slag discharge pipe 15 is located above the separation plate 5 and is used to remove impurities on the separation plate 5 .

[0061] Specifically, by connecting the slag discharge pipe 15 on one side of the lower transfer pipe 3, a slag discharge valve 16 is installed on the slag discharge pipe 15, so that the slag discharge pipe 15 is connected to the flue gas cavity and is located above the separation plate 5. During the operation of the equipment, the impurities scraped off by the scraper plate 14 can be discharged through the slag discharge pipe 15, avoiding the accumulation of impurities inside the equipment. The setting of the slag discharge valve 16 can conveniently control the timing of slag discharge, ensure the cleanliness of the interior of the equipment, and also facilitate the centralized treatment of the discharged impurities, reducing pollution to the environment.

[0062] As mentioned above, there are two heat medium gas transmission components, which correspond to the heat medium cavities one by one and are connected to the heat medium cavities. The heat medium gas transmission components include a heat medium ring pipe 18 and a heat medium air supply pipe 20. The heat medium ring pipe 18 is connected to the heat medium cavity through multiple heat medium gas transmission pipes 19 arranged at equal angles. There are multiple heat medium air supply pipes 20, which are connected to the heat medium ring pipe 18. A heat medium valve 21 is installed on each heat medium air supply pipe 20.

[0063] As mentioned above, there are two flue gas delivery components, which correspond to the flue gas cavities one by one and are connected to the flue gas cavities. The flue gas delivery components include a flue gas ring pipe 22 and a flue gas supply pipe 24. The flue gas ring pipe 22 is connected to the flue gas cavity through multiple flue gas supply pipes 23 arranged at equal angles. There are multiple flue gas supply pipes 24, which are connected to the flue gas ring pipe 22. Each flue gas supply pipe 24 is equipped with a flue gas valve 25.

[0064] Specifically, the heat medium air delivery pipe 20 in the heat medium gas transmission component is connected to the heat medium supply system. Through the heat medium supply system, the heated gas enters the heat medium cavity through the heat medium air delivery pipe 20, the heat medium ring pipe 18, and the heat medium air delivery pipe 19, flows through the heat medium cavity through the internal threaded pipe 4 to another heat medium cavity, and circulates in the heat medium supply system through the heat medium air delivery pipe 19. The flue gas air delivery pipe 24 in the flue gas transmission component is connected to the flue gas after desulfurization and denitrification treatment, so that the flue gas circulates through the flue gas cavity in the corrugated outer pipe 1 and outside the internal threaded pipe 4. By adjusting the direction of gas transmission, the heat medium gas and the flue gas flow in opposite directions in the internal threaded pipe 4 and the corrugated outer pipe 1 respectively. This countercurrent heat exchange method greatly improves the heat exchange efficiency, can more fully utilize the heat of the heat medium gas to heat the flue gas, and effectively achieves the whitening effect. Compared with traditional downstream heat exchange, countercurrent heat exchange can achieve more efficient heat transfer under a smaller temperature difference, reducing energy waste.

[0065] As mentioned above, the central shaft 10 is provided with spiral air guide blades 17 , and the spiral air guide blades 17 are located between the multiple internally threaded tubes 4 .

[0066] Specifically, when the flue gas flows in the corrugated outer tube 1, the flue gas will generate a spiral direction through the guidance of the spiral guide vanes, which can further increase the contact between the flue gas and the internal threaded tube 4, thereby improving the heat exchange effect.

[0067] As mentioned above, when the upper transfer pipe 2 and the lower transfer pipe 3 are connected, a connecting pipe 26 is connected between the corresponding heat medium air supply pipes 20 or flue gas air supply pipes 24 between the upper transfer pipe 2 and the lower transfer pipe 3 .

[0068] like Figure 7 As shown, when used in desulfurization and denitrification systems of different scales, multiple groups of heating and whitening equipment can be selected, so that when the upper transfer pipe 2 and the lower transfer pipe 3 in each group of equipment are connected, a docking pipe 26 is connected between the corresponding heat medium air supply pipes 20 or flue gas air supply pipes 24 between the upper transfer pipe 2 and the lower transfer pipe 3, and the two adjacent central shafts 10 are connected, and a power motor 11 drives the multiple connected central shafts 10 to rotate synchronously. This design not only makes the equipment more flexible during installation and use, but also allows different modules to be combined and docked according to actual needs, and facilitates the transportation, installation and subsequent maintenance and upgrading of the equipment. The setting of the docking pipe 26 also facilitates the expansion of the equipment. Users can add or reduce modules according to actual needs to adapt to desulfurization and denitrification systems of different scales.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
