[0002] In the production of glass products, the prepared glass components need to be sent into a kiln for firing and shaping. During the firing process, a large amount of sulfur-containing flue gas is generated, and the flue gas contains a large amount of dust particles. In order to ensure that the flue gas emissions meet the national emission standards and avoid polluting the atmospheric environment, it is necessary to carry out desulfurization and dust removal treatment on the flue gas discharged from the glass kiln.

After long-term use, impurities will accumulate in the sedimentation tank, and the accumulation of impurities can easily cause blockage of the water pump and its connecting pipes, thus affecting the flue gas filtration effect. Therefore, a glass kiln flue gas desulfurization and dust removal device is proposed to address the above problems. Utility Model Content

[0008] The filter tank is provided with a cleaning component for cleaning the filter assembly, and the rotation trajectory of the side curved surface of the filter assembly intersects with the cleaning component.
[0009] After the flue gas enters the filter tank, it will be filtered by the filter assembly for dust removal.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0035] Please see Figure 1-5 As shown, a desulfurization and dust removal device for flue gas in a glass kiln includes a filter tank 1; a flue gas inlet pipe 2 is fixedly connected to the side of the filter tank 1; a second sealing cover 9 is fastened to the upper opening of the filter tank 1 by bolts; a filter assembly 3 is rotatably connected to the lower part of the second sealing cover 9; the filter assembly 3 is located inside the filter tank 1; a connecting air duct 5 is provided through the bottom of the filter tank 1; and the end of the connecting air duct 5 located inside the filter tank 1 extends into the filter assembly 3.

[0037] The filter tank 1 is provided with a cleaning component 4 for cleaning the filter assembly 3, and the rotation trajectory of the side curved surface of the filter assembly 3 intersects with the cleaning component 4.
[0038] After the flue gas enters the filter tank 1, it will be filtered by the filter component 3 for dust removal. The filtered flue gas will enter the desulfurization component 6 through the connecting air duct 5 for desulfurization treatment. When the cleaning component 4 is running, it will clean the dust attached to the filter component 3.
[0039] The filter assembly 3 includes a filter cartridge 31, which is rotatably mounted under the second sealing cover 9 and rotatably disposed inside the filter tank 1. A rotating disk 33 is provided at the bottom opening of the filter cartridge 31, and the rotating disk 33 is rotatably mounted at the bottom of the filter tank 1.
[0040] A motor 32 for driving the filter cartridge 31 to rotate is installed on the second sealing cover 9 by a fixing component. A sealing ring 34 for sealing is provided between the upper surface of the rotating disk 33 and the opening of the filter cartridge 31.
[0041] The cleaning component 4 includes a protective shell 41, which is fixed to the inner curved surface of the filter tank 1. A brush roller 42 is rotatably installed inside the opening of the protective shell 41, and the rotation trajectory of the brush roller 42 intersects with the side curved surface of the filter cylinder 31. An air extraction pipe 44 is fixed to the side of the protective shell 41. A conical cylinder 45 is installed at the end of the air extraction pipe 44 through the filter tank 1, and the conical cylinder 45 is located outside the filter tank 1. A blower 46 is installed on the air extraction pipe 44.
[0042] The central axis of the brush roller 42 passes through the bottom of the filter tank 1 and is connected to a second motor 43 for driving. The second motor 43 is installed at the bottom of the filter tank 1 by a fixing component. The center line of the air extraction pipe 44 is tangent to the side edge line of the upper part of the conical cylinder 45. A guide plate 49 for guiding is fixedly connected to the inner wall of the protective shell 41. A discharge port 47 is fixedly connected to the bottom end of the conical cylinder 45. A dust collection box 48 is provided in the bottom opening of the discharge port 47 by thread engagement. An air outlet pipe 410 is fixedly connected to the upper part of the conical cylinder 45.
[0043] The desulfurization component 6 includes a storage tank 61, which is fixed to the upwardly bent end of the connecting duct 5. The end of the connecting duct 5 extends into the storage tank 61. A first sealing cap 62 is threadedly engaged at the upper opening of the storage tank 61. A first sleeve 63 is fixedly connected to the lower part of the first sealing cap 62. A second sleeve 64 is fixedly connected to the lower part of the first sleeve 63. Filter holes 65 are evenly distributed on the side of the second sleeve 64. The end of the connecting duct 5 located inside the storage tank 61 extends into the first sleeve 63.
[0044] The exhaust pipe 8 is fixed to the side of the liquid storage tank 61 and located above the second sleeve 64.
[0045] During operation, existing glass kiln flue gas desulfurization and dust removal devices are not convenient for cleaning impurities filtered in the sedimentation tank. After prolonged use, impurities accumulate in the sedimentation tank, and this accumulation can easily clog the water pump and its connecting pipes, thus affecting the flue gas filtration effect. In this solution, the end of the flue gas inlet pipe 2 is connected to the kiln exhaust port, and the No. 2 fan 7 is controlled to operate. When the No. 2 fan 7 operates, it draws the flue gas generated by the kiln into the filter tank 1 through the flue gas inlet pipe 2. After entering the filter tank 1, the flue gas is filtered by the filter cartridge 31, which blocks particulate impurities in the flue gas and keeps them outside the filter cartridge 31. In conjunction with the control of the No. 1 motor 32, the operation of the No. 1 motor 32 drives the filter cartridge 31 to rotate inside the filter tank 1. When the filter cartridge 31 rotates, it drives the sealing ring 34 to rotate at the bottom of the filter tank 1. Under the seal of the sealing ring 34, the filter cartridge 31 is closed. The bottom opening is sealed to prevent flue gas from entering through the bottom opening of the filter cartridge 31. Driven by the No. 1 motor 32, the flue gas entering the filter tank 1 will be evenly blown to the side wall of the filter cartridge 31, so that the side wall of the filter cartridge 31 can filter the dust particles in the flue gas, thereby improving its flue gas filtration efficiency. The filtered flue gas will enter the interior of the filter cartridge 31 and enter the liquid storage tank 61 through the connecting air duct 5. The liquid storage tank 61 is filled with desulfurization liquid, and the height of the desulfurization liquid is lower than the height of the port of the connecting air duct 5. After the flue gas enters the liquid storage tank 61 through the port of the connecting air duct 5, it will flow downward and be discharged outward through the filter hole 65 opened in the No. 2 sleeve 64. During the discharge process, the flue gas will be refined into small bubbles so that the flue gas can fully react with the desulfurization liquid in the liquid storage tank 61 to remove the sulfur substances in the flue gas. Finally, the desulfurized flue gas will be discharged from the exhaust pipe 8.
[0046] When excessive dust accumulates on the filter cartridge 31, by shutting down the second blower 7 and ensuring the kiln is not in use, the second motor 43 and the first blower 46 are operated. The second motor 43 drives the brush roller 42 to rotate. With the combined rotation of the filter cartridge 31 and the brush roller 42, the brush roller 42 sweeps away the dust adhering to the outer wall of the filter cartridge 31. Under the operation of the first blower 46, the dust swept from the filter cartridge 31 is sucked into the protective shell 41 and enters the conical cylinder 45 through the exhaust pipe 44. When the dust enters the conical cylinder 45, it is guided by the guide plate 49. Under the guidance of the dust, the airflow containing dust will be directed to flow downward. Since the dust collection box 48 is set in the discharge port 47, the bottom of the cone 45 is in a closed state. When the airflow containing dust is directed downward, the dust in the airflow will fall downward due to gravity and fall into the dust collection box 48 for collection, so that the dust is separated from the airflow. The airflow after dust removal will be discharged upward through the air outlet 410, thereby achieving the function of cleaning the dust on the outside of the filter cartridge 31. By removing the dust collection box 48 from the discharge port 47, the dust collected inside can be cleaned.
[0047] It achieves the functions of flue gas desulfurization and dust removal, and can also clean the filtered dust, effectively preventing dust from accumulating in the device and affecting the flue gas desulfurization and filtration effect. Compared with traditional desulfurization and dust removal devices, it has a higher dust removal efficiency.
[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
