Description

Technical Field

[0001] This invention belongs to the field of industrial silicon flue gas desulfurization technology, and specifically relates to an industrial silicon flue gas moving bed desulfurization device. Background Technology

[0002] Industrial silicon flue gas is the industrial flue gas produced during the high-temperature reduction smelting of industrial silicon in a submerged arc furnace (reaction of silica with carbonaceous reducing agents). The temperature is 200-400℃, and it is a major source of pollution in the industry. Its core components are: dust (SiO2, unreacted silica, and carbon powder, concentration 10-80 g / m³, particle size 1-10 μm, easily diffused); and gaseous pollutants (mainly CO, containing small amounts of SO2 and NO). x Trace amounts of heavy metals (lead, zinc, etc., introduced with raw materials) must be purified to meet standards through "cooling, dust removal (mainly electrostatic precipitators and bag filters), and harmful gas treatment" before being discharged. The recovered dust can be reused, making it a key target for green production of industrial silicon. Moving bed desulfurization equipment is mainly adapted to dry and semi-dry desulfurization processes. This technical solution is mainly an improvement on the rotary spray drying desulfurization device in the semi-dry process. The top tank of a rotary spray desulfurization unit must be cleaned after use. Although the top tank is only used for temporary storage of qualified slurry, the strong alkalinity and solid particle characteristics of lime slurry can cause residual slurry to form scale, blockage, or corrosion inside the tank. If not cleaned, it will directly affect the operation of subsequent systems. Traditional cleaning methods generally include draining the slurry, high-pressure flushing, manual scraping, and neutralization treatment. Acidic residues can be neutralized with an alkaline solution, followed by a second flush and inspection and drying. However, during the manual scraping stage, some stubborn impurities may stick to the inner wall of the top tank. When scraping manually, it is easy to damage the inner wall of the top tank. Damage to the top tank will result in significant economic losses, and if it is not dealt with in time, it will affect the subsequent work process. Summary of the Invention

[0003] The purpose of this invention is to provide an industrial silicon flue gas moving bed desulfurization device, which has the advantage of adding a protective plate to the inner wall of the top tank, improving the ease of cleaning while preventing the inner wall of the top tank from being scratched.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an industrial silicon flue gas moving bed desulfurization device, comprising a support frame, a reaction tank bolted inside the support frame, a lower flue gas inlet pipe welded to the lower end of one side of the reaction tank, a flue gas exhaust pipe welded to the lower end of the other side of the reaction tank, a filter element detachably connected inside the flue gas exhaust pipe, a dustproof bag detachably connected to the surface of the filter element, a top tank bolted to the upper end of the reaction tank, a hole opened at the bottom of the top tank, a through hole opened on one side of the top tank, a first water pump bolted to the top of the support frame, one end of the first water pump communicating with the top tank through the hole, a second liquid delivery pipe fixedly connected to the other end of the first water pump, the second liquid delivery pipe being disposed inside the reaction tank, a spray head bolted to the lower end of the second liquid delivery pipe, a cleaning assembly disposed inside the top tank, a cover threadedly connected to the upper end of the top tank, an upper flue gas inlet pipe welded to the upper end of the top tank, one end of the upper flue gas inlet pipe being disposed inside the reaction tank; A slurry tank is provided on one side of the support. A motor is bolted to the upper end of the slurry tank. An agitator is fixedly connected to the output end of the motor via a coupling. The agitator is located inside the slurry tank. A second water pump is bolted to the upper end of the slurry tank. Both ends of the second water pump are detachably connected to first delivery pipes. One set of the first delivery pipes is located inside the slurry tank, and the other set of the first delivery pipes passes through the cover and is located inside the top tank.

[0005] Using the above technical solution, during operation, one end of the lower and upper flue pipes is connected to an external device for discharging industrial silicon fumes. Then, lime slurry is prepared inside the slurry tank. During preparation, a motor drives a stirring paddle to rotate inside the slurry tank, accelerating the uniform mixing of the lime slurry. After the lime slurry is prepared, a second water pump uses the first delivery pipe to transport the lime slurry into the top tank. The transported lime slurry is temporarily stored inside the top tank. The cleaning component separates the top tank from the lime slurry, so the lime slurry is located inside the cleaning component. During desulfurization operation, external equipment discharges flue gas into the reaction tank through the upper and lower flue pipes. Subsequently, the first water pump uses the second delivery pipe to draw lime slurry from the top tank into the reaction tank, and a rotary atomizer dissipates the lime slurry. The solution is sprayed into the flue gas inside the reaction tank in the form of an atomized liquid. Acidic components such as sulfur dioxide in the flue gas are absorbed and neutralized by alkaline droplets, while the droplets evaporate and vaporize. The atomization, absorption, and drying process is quickly completed inside the reaction tank, ultimately producing dry ash particles such as calcium sulfite. Some of the ash particles fall to the bottom of the reaction tank. When a certain amount is accumulated, the bottom of the reaction tank is opened and the ash is discharged. The remaining ash enters the dust collector bag inside the exhaust pipe and is adsorbed. The filter element is used to support the dust collector bag. When it is necessary to clean the cleaning components inside the top tank, the cleaning structure can be quickly disassembled. By adjusting the movement of the internal structure of the cleaning component, the cleaning component can be cleaned quickly. When the cleaning component is damaged or aged during use, the corresponding structure can be disassembled and replaced.

[0006] The present invention is further configured such that: the cleaning component includes a fixed shell, the fixed shell is welded to the upper end of one side of the top tank surface, and the fixed shell covers the outer surface of the through hole, and the fixed shell and the inside of the through hole are slidably connected to a positioning block.

[0007] Using the above technical solution, the slot on one side of the third protection plate presses the inclined surface of the positioning block. Since the inclined surface of the positioning block being pressed is made of tempered glass and has a relatively smooth surface, the positioning block will retract into the fixed shell due to the pressure.

[0008] The invention is further configured such that: the positioning block and one side of the fixed shell are both connected by a telescopic spring through a spring fixing member, and the telescopic springs are jointly arranged inside the fixed shell and the through hole; and a connecting block is detachably connected to the middle of the bottom of the top tank.

[0009] Using the above technical solution, the telescopic spring can push the positioning block to be positioned inside the slot.

[0010] The present invention is further configured such that: a base plate is detachably connected to the surface of the connecting block, and a circular hole corresponding to the hole is opened in the middle of both the base plate and the surface of the connecting block; and a first protective plate is detachably connected to the inside of the top tank.

[0011] Using the above technical solution, the connecting block is installed inside the bottom plate, making it easy to remove the bottom plate from inside the top tank.

[0012] The present invention is further configured such that: a second protective plate is slidably connected inside the first protective plate, a third protective plate is slidably connected inside the second protective plate, a first limiting groove is provided at the upper end of the second protective plate, and a slot is provided on the surface of the third protective plate, and the slot is detachably connected to the positioning block.

[0013] By adopting the above technical solution, the first protective plate, the second protective plate, and the third protective plate can isolate the top tank from the lime slurry, thereby protecting the top tank.

[0014] The present invention is further configured such that: a second limiting groove is provided on the upper end of the third protective plate; a first screw is threadedly connected to one side of the upper end of the first protective plate, and the first screw is slidably connected to the first limiting groove; a second screw is threadedly connected to one side of the upper end of the second protective plate, and the second screw is slidably connected to the second limiting groove.

[0015] Using the above technical solution, the second screw slides inside the second limiting groove, which can limit the third protective plate and prevent the third protective plate from detaching from the inside of the second protective plate. The first screw slides inside the first limiting groove, which can limit the second protective plate and prevent the second protective plate from detaching from the inside of the first protective plate.

[0016] The present invention is further configured such that: a third limiting groove is provided inside the first protective plate and the second protective plate; an arc-shaped strip is welded to the lower end of one side of the inner wall of the second protective plate and the third protective plate; and the arc-shaped strip is slidably connected to the third limiting groove.

[0017] Using the above technical solution, the arc-shaped strip can slide inside the third limiting groove, which can support the second protective plate inside the first protective plate, and support the third protective plate inside the third protective plate.

[0018] The present invention is further configured such that: an arc-shaped shell is slidably connected to the upper end of the surface of the first protective plate, scrapers are bolted to the three sides of the lower end of the arc-shaped shell, and connecting plates are welded to both ends inside the arc-shaped shell.

[0019] Using the above technical solution, the scraper can remove impurities from the surface of the first protective plate.

[0020] The present invention is further configured such that: an arc-shaped rod is welded between the two sets of connecting plates, and industrial alkali-resistant canvas is detachably connected to both the arc-shaped rod and the surface of the connecting plates; a fourth screw is threadedly connected to both ends of one set of industrial alkali-resistant canvas and the two ends of the arc-shaped rod; a storage shell is detachably connected to the surface of the arc-shaped shell, and a third screw is threadedly connected between the storage shell and the arc-shaped shell.

[0021] Using the above technical solution, industrial alkali-resistant canvas can clean water from the surface of the first protective plate and the cleaned area, making it convenient for storage.

[0022] In summary, the present invention has the following beneficial effects: 1. The design of the first protective plate, the second protective plate and the third protective plate can protect the inner wall of the top tank, prevent stubborn impurities from sticking to the inner wall of the top tank and causing damage during the cleaning process, and when storing the second and third protective plates, the cleaning of the second and third protective plates can be completed in the preliminary stage, reducing the trouble of subsequent cleaning. 2. The design of the slot, telescopic spring and positioning block allows for quick assembly and disassembly of the cleaning component; 3. The design of the second screw, the second limiting groove, the first screw and the first limiting groove allows the first protective plate, the second protective plate and the third protective plate to be disassembled separately, which allows for quick replacement of damaged parts and reduces costs. 4. Through the design of the scraper and industrial alkali-resistant canvas, impurities on the surface of the first protective plate can be scraped off, and residual moisture in the scraped areas can be absorbed.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] refer to Figures 1-13An industrial silicon flue gas moving bed desulfurization device includes a support frame 1. A reaction tank 3 is bolted inside the support frame 1. A lower flue gas inlet pipe 2 is welded to the lower end of one side of the reaction tank 3, and a flue gas exhaust pipe 4 is welded to the lower end of the other side of the reaction tank 3. A filter element 14 is detachably connected inside the flue gas exhaust pipe 4, and a dustproof bag is detachably connected to the surface of the filter element 14. A top tank 7 is bolted to the upper end of the reaction tank 3. A hole 20 is opened at the bottom of the top tank 7, and a through hole 19 is opened on one side of the top tank 7. A first water pump 6 is bolted to the top of the support frame 1, and one end of the first water pump 6 is connected to the top tank 7 through the hole 20. A second liquid delivery pipe 16 is fixedly connected to the other end of the first water pump 6, and the second liquid delivery pipe 16 is set inside the reaction tank 3. A spray head is bolted to the lower end of the second liquid delivery pipe 16. A cleaning component 18 is set inside the top tank 7. A cover 8 is threaded to the upper end of the top tank 7. An upper flue gas inlet pipe 5 is welded to the upper end of the top tank 7, and one end of the upper flue gas inlet pipe 5 is set inside the reaction tank 3.

[0028] A slurry tank 12 is provided on one side of the support 1. A motor 11 is bolted to the upper end of the slurry tank 12. An agitator 15 is fixedly connected to the output end of the motor 11 through a coupling. The agitator 15 is located inside the slurry tank 12. A second water pump 10 is bolted to the upper end of the slurry tank 12. Both ends of the second water pump 10 are detachably connected to first delivery pipes 9. One set of first delivery pipes 9 is located inside the slurry tank 12, and the other set of first delivery pipes 9 passes through the cover 8 and is located inside the top tank 7.

[0029] Brief description of the usage process: During use, one end of the lower flue pipe 2 and the upper flue pipe 5 are connected to the external equipment for discharging industrial silicon fumes. Then, lime slurry is prepared inside the slurry tank 12. During preparation, the motor 11 drives the stirring paddle 15 to rotate inside the slurry tank 12, thus accelerating the uniform mixing of the lime slurry. After the lime slurry is prepared, the second water pump 10 uses the first conveying pipe 9 to transport the lime slurry into the top tank 7. The transported lime slurry is temporarily stored inside the top tank 7. The cleaning component 18 separates the top tank 7 from the lime slurry, so the lime slurry is located inside the cleaning component 18. During desulfurization operation, external equipment discharges flue gas into the reaction tank 3 through the upper flue pipe 5 and the lower flue pipe 2. Subsequently, the first water pump 6 uses the second conveying pipe to draw the lime slurry from the top tank 7 into the reaction tank 3, and the rotary atomizer 17 atomizes it. The lime slurry is sprayed into the flue gas inside the reaction tank 3 in the form of atomization. The acidic components such as sulfur dioxide in the flue gas are absorbed and neutralized by the alkaline droplets. At the same time, the droplets evaporate and vaporize, and the atomization, absorption and drying process is completed rapidly inside the reaction tank 3, finally generating dry ash particles such as calcium sulfite. Some of the ash particles fall to the bottom of the reaction tank 3. When a certain amount is stored, the bottom of the reaction tank 3 is opened and the ash is discharged. The other part of the ash enters the dust collector bag 13 in the flue pipe 4 and is adsorbed. The filter element 14 is used to support the dust collector bag 13. When it is necessary to clean the cleaning component 18 inside the top tank 7, the cleaning structure can be quickly disassembled. By adjusting the movement of the internal structure of the cleaning component 18, the cleaning component 18 can be cleaned quickly. When the cleaning component 18 is damaged or aged during use, the corresponding structure can be disassembled and replaced.

[0030] Example 2:

[0031] Based on Example 1, and referring to Figure 3 , Figures 5-11 , Figure 13 The cleaning component 18 includes a fixed shell 1812, which is welded to the upper end of one side of the surface of the top tank 7 and covers the outer surface of the through hole 19. The fixed shell 1812 and the through hole 19 are slidably connected to a positioning block 1814.

[0032] The positioning block 1814 and the inner side of the fixed shell 1812 are both connected by a telescopic spring 1813 through a spring fixing component, and the telescopic spring 1813 is jointly set inside the fixed shell 1812 and the through hole 19. The bottom center of the top tank 7 is detachably connected to a connecting block 1803.

[0033] A base plate 1801 is detachably connected to the surface of the connecting block 1803. Both the base plate 1801 and the connecting block 1803 have a round hole 1802 corresponding to the hole 20 in the middle of their surfaces. A first protective plate 1804 is detachably connected to the inside of the top tank 7.

[0034] The first protective plate 1804 is internally slidably connected to the second protective plate 1805, and the second protective plate 1805 is internally slidably connected to the third protective plate 1806. The upper end of the second protective plate 1805 is provided with a first limiting groove 1808, and the surface of the third protective plate 1806 is provided with a slot 1824, and the slot 1824 is detachably connected to the positioning block 1814.

[0035] The upper end of the third protective plate 1806 is provided with a second limiting groove 1810. The upper side of the first protective plate 1804 is threaded with a first screw 1807, and the first screw 1807 is slidably connected to the first limiting groove 1808. The upper side of the second protective plate 1805 is threaded with a second screw 1809, and the second screw 1809 is slidably connected to the second limiting groove 1810.

[0036] The first protective plate 1804 and the second protective plate 1805 are both provided with a third limiting groove 1811. The lower end of one side of the inner wall of the second protective plate 1805 and the third protective plate 1806 are both welded with an arc-shaped strip 1823, and the arc-shaped strip 1823 is slidably connected to the third limiting groove 1811.

[0037] An arc-shaped shell 1817 is slidably connected to the upper end of the surface of the first protective plate 1804. Scrapers 1820 are bolted to the three sides of the lower end of the arc-shaped shell 1817. Connecting plates 1818 are welded to both ends inside the arc-shaped shell 1817.

[0038] An arc-shaped rod 1819 is welded between the two sets of connecting plates 1818. Industrial alkali-resistant canvas 1822 is detachably connected to both the arc-shaped rod 1819 and the surface of the connecting plate 1818. The two ends of one set of industrial alkali-resistant canvas 1822 are threaded to the two ends of the arc-shaped rod 1819 respectively with a fourth screw 1821. A storage shell 1815 is detachably connected to the surface of the arc-shaped shell 1817. A third screw 1816 is threaded between the storage shell 1815 and the arc-shaped shell 1817.

[0039] Brief description of usage: When disassembling and cleaning the cleaning assembly 18 from the top tank 7, the third protective plate 1806 can be pushed towards the second protective plate 1805. During the movement of the second protective plate 1805, the slot 1824 on one side of the third protective plate 1806 will press against the inclined surface of the positioning block 1814. Since the inclined surface of the positioning block 1814 is made of tempered glass and has a relatively smooth surface, the positioning block 1814 will retract into the fixing shell 1812 due to the pressure. (The telescopic spring 1813 is used to push the positioning block 1814 into the slot 1824 when installing the cleaning assembly 18. This will fix the third protective plate 1806 inside the top tank 7, preventing the cleaning assembly 18 from being disturbed.) In the event of detachment, the movement of the third protective plate 1806 will not be obstructed. When the third protective plate 1806 is retracted into the second protective plate 1805 (the third protective plate 1806 and the second protective plate 1805 fit together perfectly), the second limiting groove 1810 at the upper end of the third protective plate 1806 will slide on the surface of the second screw 1809, and impurities on the surface of the third protective plate 1806 will be scraped off by the receiving opening of the second protective plate 1805. When the second protective plate 1805 is then retracted into the first protective plate 1804 (the first protective plate 1804 and the second protective plate 1805 fit together perfectly), the first limiting groove 1808 will slide on the surface of the first screw 1807, and impurities on the surface of the second protective plate 1805 will be scraped off. The material will be scraped off by the receiving opening of the first protective plate 1804. Furthermore, the movement of the third protective plate 1806 and the second protective plate 1805 both cause the arc-shaped strip 1823 to slide inside the third limiting groove 1811. Since neither end of the second limiting groove 1810 nor the first limiting groove 1808 is open, when the second screw 1809 and the first screw 1807 are respectively limited inside the second limiting groove 1810 and the first limiting groove 1808, the third protective plate 1806 will not move out of the second protective plate 1805, nor will the second protective plate 1805 move out of the first protective plate 1804. The storage of the second protective plate 1805 and the third protective plate 1806 not only reduces the height of the first protective plate 1804 and the second protective plate 1804, but also... The space occupied by the second and third protective plates 1805 and 1806 is also used to clean the second and third protective plates 1805 and 1806, saving time for subsequent cleaning. After storage, when cleaning the cleaning component 18 is removed from the top tank 7 and the surface of the first protective plate 1804 is cleaned, the third screw 1816 is removed and the storage shell 1815 is removed from the surface of the first protective plate 1804. Then, while pushing the first protective plate 1804 to slide inside the arc-shaped shell 1817, the arc-shaped shell 1817 is also pulled to slide on the surface of the first protective plate 1804. This can speed up the cleaning of the first protective plate 1804. While the first protective plate 1804 is moving, soft and stubborn impurities on the surface will be scraped off by the scraper 1820.Furthermore, the industrial alkali-resistant canvas 1822 set on the surface of the arc-shaped rod 1819 will also move with the scraper 1820 and wipe the area scraped by the scraper 1820, thus wiping away residual water on the surface of the first protective plate 1804. When the industrial alkali-resistant canvas 1822 needs to be replaced, the fourth screw can be removed and replaced. If the first protective plate 1804, the second protective plate 1805, or the third protective plate 1806 is damaged and cannot be used, the corresponding second screw 1809 or first screw 1807 can be removed from the second limiting groove 1810 or the first limiting groove 1808, respectively. The plate is removed from the inside. This eliminates the need for the second screw 1809 to limit the second limiting groove 1810 and the first screw 1807 to limit the first limiting groove 1808. This allows the corresponding first protective plate 1804, second protective plate 1805, or third protective plate 1806 to be separated and replaced or repaired accordingly. Since the arc-shaped shell 1817 can be removed from the surface of the first protective plate 1804, and the arc dimensions of the arc-shaped shell 1817 correspond to the arc dimensions of the bottom plate 1801, the scraper on the surface of the arc-shaped shell 1817 can be used to scrape away impurities from the surface of the bottom plate 1801 removed from the inside of the top tank 7.

[0040] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0041] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
