[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The gas dust removal device of this invention includes a housing 1, a cylinder 2, and a dust removal assembly 3. The outer wall of the cylinder 2 is in contact with the inner wall of the housing 1. The cylinder 2 has multiple independent filter sections 22. The cylinder 2 is rotatable relative to the housing 1 to adjust the position of the filter sections 22. The cylinder 2 is suitable for placing filter media 21. The dust removal assembly 3 is disposed inside the housing 1 and is connected to one or more of the filter sections 22. The dust removal assembly 3 is used to clean the filter sections 22. The filter section 22 has a filtering position and a dust removal position. When the filter section 22 is in the filtering position, it filters the gas. When the filter section 22 is in the dust removal position, at least one of the multiple filter sections 22 corresponds to the dust removal assembly 3.

[0025] Specifically, such as Figures 1-3 As shown, both the shell 1 and the cylinder 2 are cylindrical. The outer wall of the cylinder 2 is in contact with the inner wall of the shell 1, and the cylinder 2 is rotatable relative to the shell 1. The position of the filter section 22 is adjusted by rotating the cylinder 2. When the cylinder 2 rotates to adjust one or more filter sections 22 to the filtration position, the filter section 22 filters the gas. When the cylinder 2 rotates to adjust one or more filter sections 22 to the dust removal position, the filter section 22 is connected to the dust removal assembly 3, and the dust removal assembly 3 cleans the filter section 22.

[0026] It is understandable that filter media 21 of a certain height is placed inside the cylinder 2. Dust-laden gas enters the dust collector and is filtered by the filter section 22 located at the filtration position. The dust content in the filter media 21 in the filter section 22 increases. When the filter section 22 removes dust from the gas for the filtration time or when the dust content in the particulate filter media 21 of the filter section 22 reaches more than 90% of the saturation value, the rotating drum is rotated to adjust the filter section 22 to the dust removal position and the filter section 22 is cleaned until the dust removal time of the filter section 22 is reached or the dust content in the particulate filter media 21 of the filter section 22 drops to less than 10% of the saturation value, at which point the dust removal can be stopped.

[0027] It should be noted that the filtration time and cleaning time vary depending on the content and type of dust. This embodiment of the invention does not impose specific limitations on the filtration time, cleaning time, or the proportion of dust content in the specific particulate filter media 21 reaching saturation. The filtration time is determined by the actual dust content of the gas filtered by the filter section 22, the type of filter media 21, and the dust deposition state within the filter media 21, thereby adjusting the dust removal performance of the gas dust removal device. Furthermore, in actual implementation, the gas dust removal device can be test-run to determine the saturation time of the particulate filter media 21, and then the filtration time of the filter section 22 can be determined based on this time.

[0028] For example, the filter media 21 can be a granular desulfurizing agent with desulfurization activity, realizing integrated operation of desulfurization and dust removal. The filter media 21 can also be made of high-temperature resistant granules with adsorption properties, such as quartz sand, sea sand, expanded perlite, etc. The particle size of the filter media 21 is small-diameter particles, that is, granular filter media 21 with a particle size of less than 1 mm. The dust content of the granular filter media 21 can be detected by opening a detection hole on the cylinder 2, taking out a portion of the granular filter media 21 from the filter section 22 for testing to determine the dust content of the granular filter media 21.

[0029] For example, the cylinder 2 includes 12 filter sections 22, with 11 filter sections 22 in the filtration position and 1 filter section 22 in the dust removal position. That is, the 11 filter sections 22 remove dust from the gas, and the dust removal assembly 3 cleans the 1 filter section 22. When it is necessary to clean the other 11 filter sections 22, the cylinder 2 is rotated so that the 11 filter sections 22 are sequentially positioned in the dust removal position, and the dust removal assembly 3 cleans the filter sections 22 until the dust removal work of all 12 filter sections 22 is completed. The cylinder 2 can also be configured with 6 filter sections 22, with 5 filter sections 22 in the filtration position and 1 filter section 22 in the dust removal position. This embodiment of the invention does not specifically limit the number of filter sections 22; the specific implementation shall prevail.

[0030] For example, the volume of each filter section 22 can be set to be the same or different, as long as it can be realized that rotating the cylinder 2 can make some filter sections 22 located in the filtration position and other filter sections 22 located in the dust removal position. The filter section 22 located in the filtration position filters the gas, and the dust removal component 3 cleans the filter section 22 located in the dust removal position, so as to realize continuous dust removal and continuous dust removal of the gas dust removal device.

[0031] Optionally, the operating temperature range of the gas dust removal device is room temperature to 600℃, the dust content of the gas that can be treated is 100-2000mg / m3, and the resistance range of the gas dust removal device is 2-10Kpa. After the granular filter media 21 has been running for a period of time, a large amount of dust will adhere to the filter media 21, and the gaps between the filter media 21 will become smaller, making it more and more difficult for the gas to pass through. The resistance of the gas passage increases. When the resistance exceeds 10Kpa, the filtration effect of the gas dust removal device is difficult to guarantee, and it is also easy to damage the equipment.

[0032] In this embodiment of the invention, the cylinder 2 and the shell 1 are set to be cylindrical. Since the cylinder 2 needs to be rotated so that it rotates relative to the shell 1, the cylindrical shape allows the inner side of the shell 1 to rotate without gaps with the outer side of the cylinder 2, preventing the gas to be dusted from escaping through the gap between the shell 1 and the cylinder 2, thereby improving the dust removal efficiency of the gas dust removal device.

[0033] In this embodiment of the invention, multiple independent filter sections 22 are provided. One part of the filter sections 22 is located in the filtration position to filter the gas, while another part of the filter sections 22 is located in the dust removal position. The dust removal component 3 cleans the filter sections 22. Moreover, the position of the filter sections 22 can be adjusted by rotating the cylinder 2, thereby switching the filter sections 22 between the filtration position and the dust removal position. This enables the gas dust removal device to perform dust removal while continuously removing dust, thus improving the dust removal efficiency.

[0034] In some embodiments, the dust removal assembly 3 includes an air suction hood 31 and a first air distribution plate 32. The air suction hood 31 and the first air distribution plate 32 are arranged at intervals in the height direction of the cylinder 2. At the dust removal position, at least one of the plurality of filter sections 22 is connected to the air suction hood 31, the first air distribution plate 32 is connected to the cylinder 2, and the first air distribution plate 32 is used to seal the filter section 22 that is connected to the air suction hood 31 among the plurality of filter sections 22.

[0035] Specifically, the lower end of the suction hood 31 is connected to the upper end of the cylinder 2, and the first air distribution plate 32 is connected to the lower end of the cylinder 2. When the filter section 22 is in the dust removal position, the first air distribution plate 32 seals the lower end of the filter section 22, and the upper end of the filter section 22 is connected to the suction hood 31.

[0036] The suction hood 31 is connected to the upper end of the filter section 22 located at the dust removal position, and the first air distribution plate 32 is connected to the lower end of the filter section 22 located at the dust removal position. The first air distribution plate 32 is airtight, and the filter section 22 located at the dust removal position is formed into a sealed area through the suction hood 31 and the first air distribution plate 32.

[0037] It should be noted that the cross-sectional area of ​​the suction hood 31 is the same as the cross-sectional area of ​​the filter section 22 located at the dust removal position, so as to ensure that the suction hood 31 can cover the filter section 22 located at the dust removal position when it sucks air. The area of ​​the first air distribution plate 32 is the same as the cross-sectional area of ​​the suction hood 31. By sealing the lower end of the filter section 22 located at the dust removal position through the first air distribution plate 32, the suction hood 31 can perform back-blowing fluidization dust removal on the filter section 22 located at the dust removal position, thereby improving the dust removal efficiency of the dust removal assembly 3.

[0038] Optionally, a silicone sheet can be installed between the first air distribution plate 32 and the cylinder 2 for sealing, reducing the leakage of gas from the gap between the cylinder 2 and the first air distribution plate 32, and improving the sealing performance of the gas dust removal device.

[0039] For example, a cantilever connecting pipe can be installed, and the suction hood 31 and the cantilever connecting pipe are connected by a sleeve-type movable connection. At the same time, a tension spring is installed on the cantilever connecting pipe, and the tension spring applies pressure to the suction hood 31, so that the lower section of the suction hood 31 and the cylinder 2 are always in close planar contact, ensuring that the leakage is within a reasonable range.

[0040] In some embodiments, the housing 1 is provided with a first inlet 11 and a first outlet 12. The first inlet 11 is opened between the first air distribution plate 32 and the air intake hood 31, and the first outlet 12 is connected to the air intake hood 31.

[0041] Specifically, a first inlet 11 is provided at the lower right end of the shell 1, and a first outlet 12 is provided at the upper right end of the shell 1. The first outlet 12 is connected to the suction hood 31. A through hole is provided on the cylinder 2 at a position corresponding to the position of the first inlet 11. Under the suction of the suction hood 31, air enters the cylinder 2 through the first inlet 11 and the through hole in sequence, cleans the filter material 21 in the filter section 22 located at the dust cleaning position, and then flows out from the first outlet 12.

[0042] In some embodiments, the gas dust removal device further includes a rotating component 4, which includes a rotating shaft 41 and a driver 42. The rotating shaft 41 is connected to the driver 42, and one end of the rotating shaft 41 extends into the cylinder 2 and is connected to the cylinder 2. The rotating component 4 is used to drive the cylinder 2 to rotate.

[0043] Specifically, the lower end of the rotating shaft 41 extends into the cylinder 2 and is connected to the cylinder 2, while the upper end of the rotating shaft 41 is located outside the cylinder 2. The driver 42 is connected to the rotating shaft 41 and drives the rotating shaft 41 to rotate. The rotation of the rotating shaft 41 causes the cylinder 2 to rotate relative to the housing 1, thereby adjusting the position of the filter section 22. That is, the filter section 22 located in the filtration position is rotated to the dust removal position, and the filter section 22 located in the dust removal position is rotated to the filtration position, so that the dust removal assembly 3 can clean each filter section 22.

[0044] In this embodiment of the invention, the rotating component 4 enables the cyclic switching of the filter section 22 between the filtration position and the dust removal position. The dust removal component 3 cleans the filter section 22 located in the dust removal position, while the filter section 22 located in the filtration position removes dust from the gas. This allows the gas dust removal device to perform dust removal while continuously removing dust, thereby improving the dust removal efficiency.

[0045] In some embodiments, the gas dust removal device further includes a baffle 5, which extends along the height direction of the cylinder 2. One end of the baffle 5 is connected to the inner wall surface of the cylinder 2, and the other end of the baffle 5 is connected to the rotating shaft 41.

[0046] Specifically, such as Figures 2-3 As shown, the partition 5 extends in the vertical direction. The end of the partition 5 near the cylinder 2 is connected to the inner wall of the cylinder 2, and the end of the partition 5 near the rotating shaft 41 is connected to the rotating shaft 41. The partition 5 divides the inside of the cylinder 2 into multiple independent filter sections 22.

[0047] For example, partition 5 is an airtight partition 5.

[0048] In some embodiments, there are multiple partitions 5, which are arranged at intervals in the circumferential direction of the cylinder 2 to divide the cylinder 2 into multiple independent filter sections 22.

[0049] Specifically, there are multiple partitions 5, and the multiple partitions 5 can divide the cylinder 2 into multiple independent filter sections 22.

[0050] It should be noted that the number of baffles 5 can be determined according to the cross-sectional area of ​​different cylinders 2, and then the cross-sectional area of ​​each filter section 22 can be determined. By changing the cross-sectional area of ​​the filter section 22, the amount of gas required for the cleaning assembly 3 to perform fluidized cleaning of the filter section 22 and the amount of dust-laden gas to be treated after cleaning can be flexibly adjusted.

[0051] After the dust removal assembly 3 cleans the filter section 22, the gas flowing out from the first outlet 12 still needs to be treated before it can be discharged. By reducing the cross-sectional area of ​​the filter section 22, the amount of gas required by the dust removal assembly 3 to clean the filter section 22 is reduced, thereby reducing the amount of dust-laden gas to be treated after cleaning, and thus reducing the energy consumption.

[0052] After dust removal, the dusty air awaiting treatment is subsequently processed by methods such as bag filter dust collector and water dissolution. Once the dust is completely removed, it can be directly discharged into the air.

[0053] For example, the number of partitions 5 can be set to 3, 4, 6, 8, or 12.

[0054] In some embodiments, the gas dust removal device further includes a second air distribution plate 6, which is connected to the first air distribution plate 32 and is arranged at an angle.

[0055] Specifically, the second air distribution plate 6 is located below the filter section 22 at the filtration position, that is, the first air distribution plate 32 is located below the filter section 22 at the dust removal position. The first air distribution plate 32 is a flat plate that is not airtight. The second air distribution plate 6 is connected to the first air distribution plate 32 and is an inclined plate.

[0056] In some embodiments, the housing 1 is provided with a second inlet 13 and a second outlet 14. The second inlet 13 is connected to one end of the filter section 22 located at the filter position, and the second outlet 14 is connected to the other end of the filter section 22 located at the filter position.

[0057] Specifically, a second inlet 13 is provided at the upper left end of the shell 1, and a second outlet 14 is provided at the lower left end of the shell 1. The cylinder 2 is filled with a certain height of granular filter material 21. The gas to be filtered enters the cylinder 2 through the second inlet 13, and after being filtered by the filter material 21 in the cylinder 2, it flows out from the second outlet 14.

[0058] In some embodiments, the gas dust removal device further includes a first wire mesh 7 and a second wire mesh 8, the first wire mesh 7 and the second wire mesh 8 being symmetrically arranged in the height direction of the cylinder 2, the first wire mesh 7 being connected to one end of the cylinder 2, and the second wire mesh 8 being connected to the other end of the cylinder 2.

[0059] Specifically, the first wire mesh 7 is connected to the upper end of the cylinder 2, and the second wire mesh 8 is connected to the lower end of the cylinder 2. The first wire mesh 7 and the second wire mesh 8 are set to intercept the filter material 21. The first wire mesh 7 can prevent the filter material 21 from escaping from the top of the cylinder 2 when the dust removal assembly 3 cleans the filter section 22, and the second wire mesh 8 can prevent the filter material 21 from escaping from the bottom of the cylinder 2 when the filter section 22 filters the gas.

[0060] Optionally, the lower surface of the suction hood 31 is in contact with the first wire mesh 7, and a silicone sheet is provided between the suction hood 31 and the first wire mesh 7 for sealing. The silicone sheet is located on the outside of the suction hood 31 and the first wire mesh 7 to reduce the leakage of gas from the contact point between the suction hood 31 and the first wire mesh 7.

[0061] In some embodiments, the gas dust removal device further includes a valve 9, which is connected to the first inlet 11, and the valve 9 is a one-way valve.

[0062] Specifically, valve 9 is connected to the first inlet 11 to control the opening and closing of the first inlet 11, and valve 9 is set as a one-way valve to ensure that gas can only enter from the first inlet 11 and cannot flow out from the first inlet 11, thus ensuring the cleaning efficiency of the cleaning assembly 3.
