Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection equipment, and specifically, to a temperature-raising and white plume elimination device for a desulfurization and denitrification system. Background Art

[0002] In modern industrial production, especially in industries such as power, steel, and chemical industries, burning fossil fuels will generate a large amount of flue gas containing pollutants such as sulfur dioxide, nitrogen oxides, and dust. In order to reduce the harm of these pollutants to the environment, the desulfurization and denitrification process is widely used in the flue gas treatment system. Although the pollutant content in the flue gas after desulfurization and denitrification treatment is greatly reduced, there are often problems of low temperature and high humidity. When discharged into the atmosphere, it is extremely easy to form a white plume, which not only affects the visual landscape but also may cause a series of environmental problems.

[0003] The main use of the temperature-raising and white plume elimination device in the desulfurization and denitrification system is to raise the temperature of the treated flue gas, reduce the supersaturation of water vapor in the flue gas, thereby eliminating 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, raise the temperature of the flue gas, make the water vapor in the flue gas not easily condense into small water droplets, and avoid forming a white plume to cause visual pollution to the environment. At the same time, appropriately raising the temperature of the flue gas helps to increase the lifting height of chimney emissions, promote the diffusion of pollutants in the atmosphere, reduce the pollutant concentration in local areas, and is of great significance for improving the regional air quality.

[0004] Currently, the commonly seen temperature-raising and white plume elimination devices on the market mainly consist of parts such as a heat exchanger, a heat medium supply system, flue gas inlet and outlet pipes, and a control system. As a key component, the common types of heat exchangers are tubular heat exchangers and plate heat exchangers. A tubular heat exchanger generally consists 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 wall. A plate heat exchanger is composed of a series of parallel metal plate sheets with corrugations stacked together. The heat medium and the flue gas flow in opposite directions in the channels between adjacent plate sheets for heat exchange.

[0005] However, in actual use, traditional tubular heat exchangers generally have a relatively large pipe diameter and sparse arrangement, 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 velocity inside the tubes is uneven, easily resulting in flow dead zones, further reducing the heat exchange efficiency. Although the plate heat exchanger increases the heat exchange area to a certain extent, its 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 the flue gas, seriously affecting the heat exchange effect. Moreover, the sealing performance of the plate heat exchanger is poor. During long-term operation, the heat medium or the flue gas is prone to leakage, which not only reduces the heat exchange efficiency of the equipment but also may cause potential safety hazards. Summary of the Invention

[0006] The present invention proposes a heating and deoxidation device for a desulfurization and denitrification system, which is used to solve the problem mentioned in the background technology that the heating and deoxidation 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.

[0008] As a preferred technical solution of the present invention, the planetary power mechanism includes two partition plates, an inner gear ring, planetary gears, a power shaft and a sun gear; The separation plate is sealingly arranged in the upper transfer tube or the lower transfer tube, and the internal threaded tube passes through and is sealingly rotatably arranged on the two separation plates; The inner gear ring is rotatably disposed on the upper transfer tube or the lower transfer tube, and the inner gear ring is located between the two separation plates; There are a plurality of planetary wheels, each of which corresponds to the internally threaded tube one by one, and each of which is arranged on the internally threaded tube, and meshes with the internal gear ring; The power shaft penetrates and is rotatably disposed between the two separation plates; The sun gear is arranged on the power shaft, and the sun gear is located between the plurality of planetary gears and meshes with the planetary gears.

[0009] Based on the above solution, the power assembly includes a central shaft and a power motor; The central shaft is disposed through the two power shafts to drive the power shafts to rotate; The power motor is installed on the upper transfer pipe, and the output end of the power motor is connected to one end of the central shaft rod.

[0010] As a preferred technical solution of the present invention, cleaning rings are hermetically and rotatably arranged on two of the partition discs close to the corrugated outer pipe side, cleaning rods are symmetrically arranged between the two internal tooth rings, the cleaning rods are arranged through the cleaning rings, and slag scraping plates in contact with the inner wall of the corrugated outer pipe are arranged on one side of each cleaning rod.

[0011] On the basis of the foregoing solution, a slag discharge pipe is communicated with one side of the lower transfer pipe, a slag discharge valve is installed on the slag discharge pipe, the slag discharge pipe is communicated with the flue gas cavity, and the slag discharge pipe is located above the partition disc for discharging impurities on the partition disc.

[0012] Further on the basis of the foregoing solution, spiral air guiding vanes are arranged on the central shaft rod, and the spiral air guiding vanes are located between a plurality of the internal thread pipes.

[0013] On the basis of the foregoing solution, the heat medium gas transmission assembly includes a heat medium ring pipe and heat medium gas supply pipes; The heat medium ring pipe is communicated with the heat medium cavity through a plurality of heat medium gas transmission pipes arranged at equal angles; A plurality of heat medium gas supply pipes are provided, the heat medium gas supply pipes are communicated and arranged on the heat medium ring pipe, and a heat medium valve is installed on each heat medium gas supply pipe.

[0014] On the basis of the foregoing solution, the flue gas transmission assembly includes a flue gas ring pipe and flue gas supply pipes; The flue gas ring pipe is communicated with the flue gas cavity through a plurality of flue gas transmission pipes arranged at equal angles; A plurality of flue gas supply pipes are provided, the flue gas supply pipes are communicated and arranged on the flue gas ring pipe, and a flue gas valve is installed on each flue gas supply pipe.

[0015] Further on the basis of the foregoing solution, when the upper transfer pipe is docked with the lower transfer pipe, a docking pipe is communicated between the corresponding heat medium gas supply pipes or flue gas supply pipes between the upper transfer pipe and the lower transfer pipe.

[0016] On the basis of the foregoing solution, the heat medium gas and the flue gas flow in opposite directions in the internal thread pipes and the corrugated elbows respectively.

[0017] The beneficial effects of the present invention are: 1. In the present invention, by providing a planetary power mechanism, the interiors of the upper transfer pipe and the lower transfer pipe are partitioned into a heat medium cavity and a flue gas cavity, such that the heat medium gas transmission assembly is correspondingly communicated with the heat medium cavity, and the flue gas transmission assembly is correspondingly communicated with the flue gas cavity. The heat medium supply pipe in the heat medium gas transmission assembly is connected to the heat medium supply system, and the flue gas supply 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 reversely inside the internal thread pipe and the corrugated outer pipe respectively. Through this countercurrent heat exchange method, the heat exchange efficiency is greatly improved, the heat of the heat medium gas can be more fully utilized to heat the flue gas, and the white smoke elimination effect can be effectively achieved. Compared with the traditional co-current heat exchange, the countercurrent heat exchange can achieve more efficient heat transfer at a smaller temperature difference, reducing the waste of energy.

[0018] 2. In the present invention, the internal thread pipe is penetrated and rotatably arranged between two planetary power mechanisms and is communicated with the two heat medium cavities. When the planetary power mechanism is driven to move by starting the power motor, the internal thread pipe rotates. When the internal thread pipe rotates, due to its special structure, the disturbance of the heat medium gas flowing inside the pipe can be increased, and by breaking the boundary layer, the heat transfer process can be strengthened. Compared with an ordinary smooth pipe, the internal thread pipe can significantly increase the heat transfer coefficient between the heat medium and the pipe wall, further improving the heat exchange capacity of the entire device and making the temperature-raising and white smoke elimination process more efficient.

[0019] 3. In the present invention, 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 vulnerable to corrosion and scaling during long-term operation. By sealing and rotatably arranging cleaning rings on both of the two partition plates close to the corrugated outer pipe side, and symmetrically arranging cleaning rods between the two internal gear rings, the cleaning rods penetrate through the cleaning rings, and a slag scraping plate in contact with the inner wall of the corrugated outer pipe is arranged on one side of each cleaning rod. When the planetary power mechanism operates, since the planet gears are restricted by the internal thread pipe and can only rotate, the internal gear rings are driven to rotate by the planet gears, and the cleaning rods are driven to rotate by the internal gear rings, so that the slag scraping plates scrape the inner wall of the corrugated outer pipe, and the impurities and dirt accumulated on the pipe wall are timely removed to prevent the influence on the heat exchange efficiency and the normal operation of the device. 4. In the present invention, a slag discharge pipe is communicated with one side of the lower transfer pipe, and a slag discharge valve is installed on the slag discharge pipe. The slag discharge pipe is communicated with the flue gas cavity and is located above the partition plate. During the operation of the device, the impurities scraped off by the slag scraping plate can be discharged through the slag discharge pipe, avoiding the accumulation of impurities inside the device. The setting of the slag discharge valve can conveniently control the timing of slag discharge, ensure the cleanliness inside the device, and at the same time facilitate the centralized treatment of the discharged impurities, reducing environmental pollution. 5. In the present invention, when used in desulfurization and denitrification systems of different scales, multiple groups of such temperature-raising and white-smoke-eliminating devices can be selected. When the upper transfer pipe and the lower transfer pipe in each group of devices are docked, a docking pipe is connected between the heat medium supply pipes or flue gas supply pipes that correspond to each other between the upper transfer pipe and the lower transfer pipe, and the adjacent two central shaft rods are connected. A power motor drives the connected multiple central shaft rods to rotate synchronously. This design not only makes the device more flexible during installation and use, and different modules can be combined and docked according to actual needs, but also facilitates the transportation, installation and later maintenance and upgrade of the device. Moreover, the setting of the docking pipe also provides convenience for the expansion of the device. Users can increase or decrease modules according to actual needs to adapt to desulfurization and denitrification systems of different scales. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 7 As shown, this embodiment proposes a temperature-raising and whitening removal device for a desulfurization and denitrification system, including a corrugated outer pipe 1, a heat medium gas transmission component, a flue gas gas transmission component and an internal threaded pipe 4.

[0025] 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 butt-jointed. As shown in the figure, flange blind butt joint is the best choice to facilitate the disassembly of the upper transfer tube 2 and the lower transfer tube 3.

[0026] 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 mechanism 001 divides 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.

[0027] like Figure 5 As shown, the planetary power mechanism 001 includes two partition plates 5, an inner gear ring 6, a planetary gear 7, a power shaft 8 and a sun gear 9. The partition plate 5 is sealed and arranged in the upper transfer tube 2 or the lower transfer tube 3. The inner threaded tube 4 passes through and is sealed and rotatably arranged on the two partition plates 5. The inner gear ring 6 is rotatably arranged on the upper transfer tube 2 or the lower transfer tube 3. The inner gear ring 6 is located between the two partition plates 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 arranged between the two partition plates 5. The sun gear 9 is arranged on the power shaft 8. The sun gear 9 is located between the multiple planetary gears 7 and meshed with the planetary gears 7.

[0028] Among them, the power component 002 includes a central shaft 10 and a power motor 11. The central shaft 10 is arranged on 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.

[0029] 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 the internal threaded tubes 4 are communicated with the two heat medium cavities.

[0030] As described above, a docking through-hole adapted to the central shaft rod 10 is also provided on the flange blind plate. The central shaft rod 10 penetrates and is rotatably arranged in the docking through-hole in a sealed manner, so as to dock the two central shaft rods 10.

[0031] Specifically, start the power motor 11. The output end of the power motor 11 can drive the central shaft rod 10 to rotate. The central shaft rod 10 drives the power shaft 8 to rotate. The rotation of the power shaft 8 drives the sun gear 9 to rotate. The sun gear 9 drives a plurality of meshing planet gears 7 to rotate. Since the inner threaded tube 4 is rotatably arranged on the dividing plate, the planet gear 7 rotates self - rotatably under the restriction of the inner threaded tube 4. The rotation of the planet gear 7 drives the internal gear ring 6 to rotate. This structural design makes the power transmission direct and efficient. The power motor 11 can stably provide power for the planetary power mechanism 001, ensuring the normal operation of the entire device. Moreover, the setting of the central shaft rod 10 ensures the synchronous rotation of the two power shafts 8, enabling the planetary power mechanisms 001 in the upper transfer pipe 2 and the lower transfer pipe 3 to work coordinately, further improving the stability of the device operation.

[0032] It should be supplemented that cleaning rings 12 are hermetically and rotatably arranged on both dividing plates 5 close to the corrugated outer tube 1. Cleaning rods 13 are symmetrically arranged between the two internal gear rings 6. The cleaning rods 13 penetrate through the cleaning rings 12. On one side of each cleaning rod 13, there is a slag scraping plate 14 in contact with the inner wall of the corrugated outer tube 1.

[0033] 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 vulnerable to corrosion and scaling during long - term operation. By hermetically and rotatably arranging cleaning rings 12 on both dividing plates 5 close to the corrugated outer tube 1, symmetrically arranging cleaning rods 13 between the two internal gear rings 6, making the cleaning rods 13 penetrate through the cleaning rings 12, and arranging a slag scraping plate 14 in contact with the inner wall of the corrugated outer tube 1 on one side of each cleaning rod 13. When the planetary power mechanism 001 operates, since the planet gear 7 can only rotate self - rotatably under the restriction of the inner threaded tube 4, the planet gear 7 drives the internal gear ring 6 to rotate, and the internal gear ring 6 drives the cleaning rod 13 to rotate, so that the slag scraping plate 14 scrapes the inner wall of the corrugated outer tube 1. By timely removing the accumulated impurities and dirt on the pipe wall, it is prevented from affecting the heat exchange efficiency and the normal operation of the device.

[0034] As described above, a slag discharge pipe 15 is connected to one side of the lower transfer pipe 3. A slag discharge valve 16 is installed on the slag discharge pipe 15. The slag discharge pipe 15 is connected to the flue gas cavity. The slag discharge pipe 15 is located above the dividing plate 5 and is used to discharge the impurities on the dividing plate 5.

[0035] Specifically, a slag discharge pipe 15 is connected to one side of the lower transfer pipe 3, and a slag discharge valve 16 is installed on the slag discharge pipe 15. The slag discharge pipe 15 is connected to the flue gas cavity and is located above the partition plate 5. During the operation of the equipment, the impurities scraped off by the slag scraping 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 inside the equipment, and at the same time facilitate the centralized treatment of the discharged impurities, reducing environmental pollution.

[0036] As described 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 component includes a heat medium ring pipe 18 and a heat medium gas supply pipe 20. The heat medium ring pipe 18 is connected to the heat medium cavity through a plurality of heat medium gas transmission pipes 19 arranged at equal angles. There are a plurality of heat medium gas supply pipes 20, and the heat medium gas supply pipes 20 are connected to the heat medium ring pipe 18. A heat medium valve 21 is installed on each heat medium gas supply pipe 20.

[0037] As described above, there are two flue gas gas transmission components, which correspond to the flue gas cavities one by one and are connected to the flue gas cavities. The flue gas gas transmission component includes 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 a plurality of flue gas transmission pipes 23 arranged at equal angles. There are a plurality of flue gas supply pipes 24, and the flue gas supply pipes 24 are connected to the flue gas ring pipe 22. A flue gas valve 25 is installed on each flue gas supply pipe 24.

[0038] Specifically, the heat medium gas supply 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 gas supply pipe 20, the heat medium ring pipe 18, and the heat medium gas transmission pipe 19, flows through the internal thread pipe 4 in the heat medium cavity to another heat medium cavity, and circulates in the heat medium supply system through the heat medium gas transmission pipe 19. The flue gas supply pipe 24 in the flue gas 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 outside the corrugated outer pipe 1 and outside the internal thread pipe 4. By adjusting the direction of gas transmission, the heat medium gas and the flue gas flow in opposite directions inside the internal thread pipe 4 and the corrugated outer pipe 1 respectively. Through this countercurrent heat exchange method, the heat exchange efficiency is greatly improved, and the heat of the heat medium gas can be used more fully to heat the flue gas, effectively achieving the whitening elimination effect. Compared with the traditional concurrent heat exchange, the countercurrent heat exchange can achieve more efficient heat transfer at a smaller temperature difference, reducing energy waste.

[0039] As described above, a spiral gas guide vane 17 is provided on the central shaft rod 10, and the spiral gas guide vane 17 is located between a plurality of internal thread pipes 4.

[0040] Specifically, when the flue gas flows in the corrugated outer pipe 1, the flue gas will generate a rotation direction under the guidance of the spiral guide vane, which can further increase the contact between the flue gas and the inner threaded pipe 4, thereby improving the heat exchange effect.

[0041] As described above, when the upper transfer pipe 2 is docked with the lower transfer pipe 3, a docking pipe 26 is connected between the corresponding heat medium supply pipes 20 or flue gas supply pipes 24 between the upper transfer pipe 2 and the lower transfer pipe 3.

[0042] As Figure 7 shown, when used in desulfurization and denitrification systems of different scales, multiple groups of temperature-rising and white-smoke-eliminating devices can be selected. When the upper transfer pipe 2 and the lower transfer pipe 3 in each group of devices are docked, a docking pipe 26 is connected between the corresponding heat medium supply pipes 20 or flue gas supply pipes 24 between the upper transfer pipe 2 and the lower transfer pipe 3, and the adjacent two central shaft rods 10 are connected, and a power motor 11 drives the connected multiple central shaft rods 10 to rotate synchronously. This design not only makes the equipment more flexible in the installation and use process, and can be combined and docked with different modules according to actual needs, but also facilitates the transportation, installation and later maintenance and upgrade of the equipment. Moreover, the setting of the docking pipe 26 also provides convenience for the expansion of the equipment, and users can increase or decrease the modules according to actual needs to adapt to desulfurization and denitrification systems of different scales.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
