Description

Technical Field

[0001] This invention relates to the field of gas treatment technology, and in particular to a wet desulfurization device and method for gas treatment. Background Technology

[0002] In gas treatment in industries such as thermal power, steel, and chemicals, wet desulfurization is the core technology for removing sulfur dioxide from flue gas. It achieves desulfurization through the contact reaction between a desulfurizing agent slurry and sulfur-containing gases. During this process, dust carried in the gas, gypsum particles generated from the desulfurization reaction, and unreacted desulfurizing agent particles, if not filtered and removed in time, will lead to deterioration of the slurry quality in the desulfurization tower, nozzle blockage, and reduced desulfurization efficiency. Therefore, staged filtration is a crucial step for the stable operation of a wet desulfurization system. By gradually separating large and small particles through filtration stages of different precision, it can prevent a single filter from clogging rapidly due to excessive load and improve filtration efficiency. However, existing filtration devices are mostly single-unit fixed structures with relatively limited functions. They are difficult to select different filtration methods according to actual needs, and cannot improve filtration efficiency based on actual requirements. Moreover, when the filter becomes clogged, the system must be shut down for cleaning, interrupting the desulfurization process. Furthermore, they lack particle dispersion and filter self-cleaning functions, making them prone to a surge in filtration resistance due to particle agglomeration.

[0003] To address the above problems, this invention proposes a wet desulfurization device and method for gas treatment. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing filtration devices, which are mostly single-unit fixed structures with limited functions. They are difficult to select different filtration methods according to actual needs, and cannot improve filtration efficiency according to actual needs. Moreover, when the filter screen is clogged, the machine needs to be stopped for cleaning, interrupting the desulfurization process. Furthermore, they lack particle dispersing and filter screen self-cleaning functions, and are prone to a surge in filtration resistance due to particle agglomeration. Therefore, this invention proposes a wet desulfurization device and wet desulfurization method for gas treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wet desulfurization device for gas treatment includes a desulfurization mechanism, the desulfurization mechanism includes a processing device, the processing device is divided into two desulfurization chambers, and a filtration processing mechanism is provided in the desulfurization mechanism; The filtration mechanism includes a drive assembly and two sets of filter assemblies, with two filter assemblies in each set. Each filter assembly is equipped with an adjustable disturbance component. A filter adjustment component is provided on one side of the filter assembly. The position of the filter assembly can be adjusted by the filter adjustment component so that the filter assembly can be used flexibly in the two desulfurization chambers.

[0006] Preferably, a diversion valve is provided above the processing device, and a discharge valve is provided below the processing device.

[0007] Preferably, the front of the processing device is sealed with two maintenance doors.

[0008] Preferably, the drive assembly includes two sets of drive shafts, each set containing four drive shafts. The drive shafts are rotatably mounted on the processing device via bearings, and a first gear is fixedly connected to one end of each drive shaft.

[0009] Preferably, one of the drive shafts is fixedly connected to the output shaft of the motor, the motor is installed in a drive box, the drive box is fixedly connected to the processing device, and a sprocket is fixedly connected to the other end of the drive shaft. The two sets of sprockets are connected by chain drive.

[0010] Preferably, the filter assembly includes filter buckets, the mesh size of the four filter buckets decreases sequentially from top to bottom, the filter buckets are located in the desulfurization chamber, and a sealing layer is fixedly connected to both sides of the filter buckets, the sealing layer being sealed in the processing device.

[0011] Preferably, the filter adjustment assembly includes two fixed brackets, which are fixedly connected to the processing device. An installation sleeve is fixedly installed on the fixed bracket, and an installation rod is slidably connected in the installation sleeve. The installation rod is fixed to the installation sleeve by bolts. An operating handle is fixedly connected to one end of the two installation rods, and the other end of the two installation rods is fixedly connected to the sealing layer.

[0012] Preferably, the adjustable disturbance component includes an outer cylinder and a screw. Both ends of the outer cylinder are rotatably mounted on both sides of the processing device and both ends of the screw via bearings. A second gear is fixedly connected to one end of the outer cylinder, and the second gear engages with the first gear by displacement. An adjusting sleeve is fitted around the outer cylinder. Both the outer cylinder and the adjusting sleeve are polygonal in shape. Scrapers are fixedly connected to both sides of the adjusting sleeve, and the scrapers overlap with the filter bucket.

[0013] Preferably, a nut is slidably connected inside the outer cylinder, the shape of the nut being adapted to the shape of the outer cylinder, magnets are fixedly connected to both sides of the nut and both sides of the inner cavity of the adjusting sleeve, adjacent magnets are magnetically connected to each other, the nut is threaded onto the screw, and two springs are sleeved on the screw, one end of each spring is fixedly connected to both ends of the nut, and the other end of each spring is fixedly connected to both ends of the screw, and the end of the screw is fixedly installed in the processing device.

[0014] A wet desulfurization method for a gas treatment wet desulfurization unit includes the following steps: S1. When the two desulfurization chambers are filtered simultaneously, the diversion valves introduce two sulfur-containing gas slurries into the two desulfurization chambers respectively, so that the sulfur-containing gas slurries enter the filter buckets sequentially for desulfurization and filtration, and the treated sulfur-containing gas slurries are discharged. S2. In the process of filtering sulfur-containing gas slurry, the transmission shaft is driven to rotate by the motor. The transmission shaft drives the sprocket to rotate. The sprocket drives the other transmission shafts to run through the chain, so that the first gear and the second gear are driven to rotate. The second gear drives the outer cylinder to rotate. The outer cylinder drives the nut and the adjusting sleeve to rotate. The adjusting sleeve drives the scraper to disturb the sulfur-containing gas slurry, thereby increasing the filtration speed of the sulfur-containing gas slurry. At the same time, the nut and the screw thread drive to achieve displacement movement. The displacement of the nut drives the magnet to move. The magnet drives the adjusting sleeve and the scraper to move through magnetic traction, so that the scraper changes position to disturb and disperse the sulfur-containing gas slurry. S3. When single-chamber filtration and multi-stage filtration are required, adjust the position of the mounting rod by operating the handle to adjust the filter assembly into a separate desulfurization chamber, and then lock the position of the mounting rod with bolts. At this time, the subsequent multi-stage filtration operation can be carried out.

[0015] Compared with the prior art, the present invention provides a wet desulfurization device and method for gas treatment, which has the following beneficial effects: 1. The wet desulfurization device and its wet desulfurization method for gas treatment separate two sets of filter components through the desulfurization chamber, allowing the two sets of filter components to operate independently, thereby improving the overall filtration efficiency. When one set of filter components is filtering, the other set of filter components can be cleaned online without stopping the machine. Furthermore, the filter components can be adjusted according to the needs of entering a single desulfurization chamber through the filter adjustment component, enabling rapid merging and forming a multi-stage filtration system, which further optimizes the filtration effect and meets diverse desulfurization treatment requirements.

[0016] 2. The wet desulfurization device and method for gas treatment drive the adjustable disturbance component to rotate the scraper and move it in the filter bucket. This can break up agglomerated particles and increase the breaking area. At the same time, it can reduce the filtration resistance of the desulfurized gas slurry and reduce the risk of filter bucket blockage.

[0017] 3. The wet desulfurization device and method for gas treatment, by driving the movement of the adjustable disturbance component, can achieve the purpose of scraping, cleaning and breaking up the filter component. In this way, regardless of whether the filter component is in a split operation state or a combined operation state, the inside of the filter bucket can always maintain an unobstructed state, thus effectively ensuring the stability and reliability of the graded filtration effect. The filter adjustment component can flexibly adjust the position of the filter component in the desulfurization chamber, so that the filter component has a split and combined mode in the desulfurization chamber, providing a flexible application scenario for the breaking and scraping function, greatly improving the filtration efficiency, and thus providing a high-quality and reliable solution for the filtration process in industrial production.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: Refer to Figures 1-4 and Figure 6 A wet desulfurization device for gas treatment includes a desulfurization mechanism 100, which includes a processing device 101. A diversion valve 103 is provided above the processing device 101 to adjust the liquid flow direction and simultaneously guide the liquid to two desulfurization chambers 102 for filtration. A discharge valve is provided below the processing device 101 to discharge the filtered slurry. Two maintenance doors 104 are sealed on the front of the processing device 101 to allow maintenance of the filter hopper 2022 by opening the sealed doors. The processing device 101 is divided into two desulfurization chambers 102, and a filtration processing mechanism 200 is provided in the desulfurization mechanism 100. The filtration unit 200 includes a drive assembly 204 and two sets of filter assemblies 202, each set containing two filter assemblies 202. Each filter assembly 202 includes a filter bucket 2022, with the mesh size of the four filter buckets decreasing sequentially from top to bottom. The filter buckets 2022 can filter desulfurization gas slurry, and the decreasing mesh size design allows for staged filtration. The two sets of filter buckets 2022 operate independently while still meeting filtration requirements. The filter buckets 2022 are located in the desulfurization... In cavity 102, sealing layers 2021 are fixedly connected to both sides of filter bucket 2022. The sealing layers 2021 are embedded in the processing device 101, thus achieving a sealing effect. The sealing layers 2021 are sealed within the processing device 101. An adjustable disturbance component 203 is provided in the filter assembly 202, and a filter adjustment component 201 is provided on one side of the filter assembly 202. The filter adjustment component 201 includes two fixing brackets 2014, which are fixedly connected to the processing device 101. A mounting sleeve 2013 is fixedly installed on the mounting bracket 2014. A mounting rod 2011 is slidably connected to the mounting sleeve 2013. The mounting rod 2011 can slide within the mounting sleeve 2013, thereby facilitating the adjustment of the position of the filter assembly 202. The mounting rod 2011 can also be fixed to the mounting sleeve 2013 with bolts, thus fixing the position of the filter assembly 202 and ensuring stable filtration. The mounting rod 2011 is fixed to the mounting sleeve 2013 with bolts at one end of each of the two mounting rods 2011. An operating handle 2012 is fixedly connected, which allows for easy control of the movement of the mounting rod 2011. This enables the mounting rod 2011 to adjust the position of the filter assembly 202, facilitating flexible adjustment of the filter assembly 202. This allows the two sets of filter assemblies 202 to be separated and operated in combination. The other ends of the two mounting rods 2011 are fixedly connected to the sealing layer 2021. The position of the filter assembly 202 can be adjusted by the filter adjustment component 201, allowing the filter assembly 202 to be used flexibly in the two desulfurization chambers 102.

[0023] In this embodiment, the two sets of filter components 202 are separated through the desulfurization chamber 102, allowing the two sets of filter components 202 to operate independently, thereby improving the overall filtration efficiency. When one set is filtering, the other set of filter components 202 can be cleaned online without stopping the machine. Furthermore, the filter adjustment component 201 can adjust the filter components 202 into a single desulfurization chamber 102 as needed, enabling rapid merging and forming a multi-level filtration system, further optimizing the filtration effect and meeting diverse desulfurization treatment requirements.

[0024] Example 2: Refer to Figures 4-11A wet desulfurization device for gas treatment includes a drive assembly 204, which includes two sets of drive shafts 2045, each set containing four drive shafts 2045. The drive shafts 2045 are rotatably mounted on the treatment device 101 via bearings, and the drive shafts 2045 are kept in stable rotation by the bearings, thereby enabling stable transmission between a first gear 2044 and a second gear 2033. One end of the drive shaft 2045 is fixedly connected to the first gear 2044, and one of the drive shafts 2045 is fixedly connected to the output shaft of a motor 2043. The motor 2043 is mounted in a drive box 2041, which is fixedly connected to the treatment device 101. The other end of the drive shaft 2045 is fixedly connected to a sprocket 2042. The two sets of sprockets 2042 are connected by a chain 2046, which can mesh with multiple sprockets 2042 to achieve long-distance power transmission and enable multiple drive shafts 2045 to move synchronously. The adjustable disturbance component 203 includes an outer cylinder 2031 and a screw 2034. Both ends of the outer cylinder 2031 are rotatably mounted on both sides of the processing device 101 and both ends of the screw 2034 via bearings. A second gear 2033 is fixedly connected to one end of the outer cylinder 2031. The second gear 2033 engages with a first gear 2044 through displacement. Power transmission is achieved through the interaction between the second gear 2033 and the first gear 2044, thereby driving the outer cylinder 2031 to rotate. An adjusting sleeve 2037 is fitted around the outer cylinder 2031. The outer cylinder 2031 and the adjusting sleeve 2037... The outer cylinder 2031 and adjusting sleeve 2037 are both designed as polygonal structures. The rotation of the outer cylinder 2031 drives the rotation of the adjusting sleeve 2037, while the adjusting sleeve 2037 can slide smoothly on the outer cylinder 2031. Scrapers 2032 are fixedly connected to both sides of the adjusting sleeve 2037, and the scrapers 2032 overlap with the filter bucket 2022. A nut 2036 is slidably connected inside the outer cylinder 2031. The shape of the nut 2036 matches the shape of the outer cylinder 2031. By also designing the nut 2036 as a polygonal structure, the outer cylinder 2031... Rotation 1 also drives the nut 2036 to rotate. Magnets 2038 are fixedly connected to both sides of the nut 2036 and both sides of the inner cavity of the adjusting sleeve 2037. Adjacent magnets 2038 are magnetically connected. The nut 2036 is threaded onto the screw 2034. Through the threaded transmission between the nut 2036 and the screw 2034, the nut 2036 can drive the adjusting sleeve 2037 to move through the attraction between the magnets 2038, thereby adjusting the position of the scraper 2032. And through the forward and reverse rotation of the motor 2043, the scraper 2032 can reciprocate in the filter hopper 2022. The screw 2 The outer sleeve of the 034 is equipped with two springs 2035. One end of each spring 2035 is fixedly connected to both ends of the nut 2036. The springs 2035 are spirally arranged so that they not only have elasticity but also torque, so that when the scraper 2032 stops working, the springs 2035 can smoothly return to their original position, thereby allowing the scraper 2032 to return to its original position, ensuring that each scraper 2032 is in the same position and that the scrapers 2032 move synchronously. The other ends of the two springs 2035 are fixed to both ends of the screw 2034, and the end of the screw 2034 is fixedly installed in the processing device 101.

[0025] In this embodiment: the motor 2043 drives the transmission shaft 2045 to rotate, which in turn drives the sprocket 2042. Under the transmission of the chain 2046, the transmission shaft 2045 rotates synchronously. The transmission shaft 2045 drives the first gear 2044, which in turn drives the second gear 2033 to rotate the outer cylinder 2031. The outer cylinder 2031 drives the scraper 2032 to rotate through the adjusting sleeve 2037. At the same time, the outer cylinder 2031 drives the nut 2036 to rotate. The nut 2036 and the screw 2034 are driven by the magnet 2038 to move the adjusting sleeve 2037, so that the scraper 2032 keeps rotating and displaces in the filter bucket 2022. This can break up the agglomerated particles and increase the breaking area. At the same time, it can reduce the filtration resistance of the desulfurization gas slurry and reduce the risk of clogging of the filter bucket 2022.

[0026] Example 3: Reference Figures 1-4 and Figure 6 A wet desulfurization device for gas treatment includes a desulfurization mechanism 100, which includes a processing device 101. The processing device 101 is divided into two desulfurization chambers 102. A filtration processing mechanism 200 is provided in the desulfurization mechanism 100. The filtration processing mechanism 200 includes a drive assembly 204 and two sets of filter assemblies 202. Each set of filter assemblies 202 has two components. An adjustable disturbance assembly 203 is provided in each filter assembly 202. A filter adjustment assembly 201 is provided on one side of each filter assembly 202. The position of the filter assembly 202 is adjusted by the filter adjustment assembly 201 so that the filter assembly 202 can be used flexibly in the two desulfurization chambers 102.

[0027] In this embodiment: by driving the adjustable disturbance component 203 to move, the filter component 202 can be scraped, cleaned, and broken up. In this way, regardless of whether the filter component 202 is in a split operation state or a combined operation state, the inside of the filter bucket 2022 can always maintain an unobstructed state, thus effectively ensuring the stability and reliability of the graded filtration effect. The filter adjustment component 201 can flexibly adjust the position of the filter component 202 in the desulfurization chamber 102, so that the filter component 202 has a split and combined mode in the desulfurization chamber 102, providing a flexible application scenario for the breaking up and scraping function, greatly improving the filtration efficiency, and thus providing a high-quality and reliable solution for the filtration process in industrial production.

[0028] A wet desulfurization method for a gas treatment wet desulfurization unit includes the following steps: S1. When the two desulfurization chambers 102 are simultaneously filtered, the diversion valve 103 introduces two sulfur-containing gas slurries into the two desulfurization chambers 102 respectively, so that the sulfur-containing gas slurries enter the filter bucket 2022 sequentially for desulfurization and filtration, and the treated sulfur-containing gas slurries are discharged. S2. In the process of filtering sulfur-containing gas slurry, the motor 2043 drives the transmission shaft 2045 to rotate, the transmission shaft 2045 drives the sprocket 2042 to rotate, and the sprocket 2042 drives the other transmission shafts 2045 to run through the chain 2046, so that the first gear 2044 and the second gear 2033 are driven to drive the outer cylinder 2031 to rotate, the outer cylinder 2031 drives the nut 2036 and the adjusting sleeve 2037 to rotate, and the adjusting sleeve 2037 drives the scraper 2032 to disturb the sulfur-containing gas slurry, thereby increasing the filtration speed of the sulfur-containing gas slurry. At the same time, the nut 2036 and the screw 2034 achieve displacement movement through thread transmission. The displacement of the nut 2036 drives the magnet 2038 to move. The magnet 2038 drives the adjusting sleeve 2037 and the scraper 2032 to move through magnetic traction, so that the scraper 2032 changes position to perform the disturbance and dispersion operation of the sulfur-containing gas slurry. S3. When single-chamber filtration and multi-stage filtration are required, adjust the position of the mounting rod 2011 by operating handle 2012 so that the filter assembly 202 is adjusted into a separate desulfurization chamber 102. At the same time, switch the second gear 2033 to mesh with the first gear 2044. Then lock the position of the mounting rod 2011 with bolts. At this time, the subsequent multi-stage filtration operation is carried out.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The second gear (2033) drives the outer cylinder (2031) to rotate. The outer cylinder (2031) drives the nut (2036) and the adjusting sleeve. (2037) Rotation, the adjusting sleeve (2037) drives the scraper (2032) to disturb the sulfur-containing gas slurry, increasing the filtration speed of the sulfur-containing gas slurry. At the same time, the nut (2036) and the screw (2034) achieve displacement movement through thread transmission. The displacement of the nut (2036) drives the magnet (2038) to move. The magnet (2038) drives the adjusting sleeve (2037) and the scraper (2032) to move through magnetic traction, so that the scraper (2032) changes position to carry out the disturbance and dispersal operation of the sulfur-containing gas slurry; S3. When single-chamber filtration and multi-stage filtration are required, adjust the position of the mounting rod (2011) by operating handle (2012) so that the filter assembly (202) is adjusted into a separate desulfurization chamber (102). Then lock the position of the mounting rod (2011) with bolts. At this time, the subsequent multi-stage filtration operation is carried out.
