Description

Technical Field

[0001] This utility model relates to the technical field of oxidation fan equipment, specifically to an oxidation fan for wet desulfurization. Background Technology

[0002] Wet desulfurization is widely used to reduce sulfur dioxide emissions in industrial waste gas. It involves contacting the waste gas with a calcium oxide solution, allowing the sulfur dioxide to be absorbed and converted into substances such as calcium sulfate. To further enhance the absorption effect, kaolin is usually added to adsorb residual sulfur dioxide. At the same time, to ensure that the sulfur dioxide can generate stable calcium sulfate, sufficient oxygen needs to be introduced through a special oxidation fan to ensure the desulfurization effect. However, in the existing technology, the outlet of the oxidation fan is easily blocked by calcium sulfate, which will reduce the working efficiency of the oxidation fan over time.

[0003] To address the aforementioned issues, Chinese patent CN211098335U discloses a high-efficiency oxidation blower for desulfurization and denitrification, comprising a load-bearing block, a shock-absorbing mechanism, an outer casing, sound-absorbing cotton, an inlet pipe, a filter screen, and an outlet pipe. The rotation of a first motor, coupled with a belt connection, drives a second rotating shaft, causing a scraper to remove reacted solids from the inner wall of the outlet pipe, preventing blockage. However, in the process of scraping the outlet pipe, the motor-driven scraping mechanism of the aforementioned oxidation blower is inflexible in installation and has high operating costs, limiting its adaptability and ease of layout, thus affecting its overall efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an oxidation blower for wet desulfurization to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An oxidation blower for wet desulfurization includes a support plate, a blower housing at the top of the support plate, an exhaust assembly through the outer side of the blower housing, an impeller through the inner side of the blower housing, a motor on one side of the impeller, and an air intake assembly through the blower housing on the other side of the impeller.

[0008] Furthermore, to improve the overall efficiency of the oxidation blower, the spiral grooves guide the airflow, causing it to rotate in the direction of the grooves and form an airflow with angular momentum. When the airflow passes over the rotating blades, the blades rotate due to the impact force of the airflow, driving the rotating block and rotating shaft to rotate. This allows the scraper and arc-shaped rod to scrape the surface of the filter plate and the shielding pipe, removing particulate matter and other deposits generated during the wet desulfurization process. This ensures the air permeability of the filter plate and the efficient operation of the oxidation blower, while also saving costs and reducing installation complexity. This ensures the adaptability and ease of layout of the oxidation blower, thereby improving its overall efficiency and exhaust components. The system includes an exhaust pipe extending through the outer side of the fan casing, a connecting pipe at one end of the exhaust pipe, a shielding pipe at one end of the connecting pipe, a filter plate at the end of the shielding pipe near the exhaust pipe, a rotating shaft running through the middle of the filter plate, several scrapers connected to the rotating shaft on the side of the filter plate away from the exhaust pipe, an arc-shaped rod at one end of each scraper cooperating with the shielding pipe, a rotating block connected to the rotating shaft on the other side of the filter plate, and several rotating blades on the outer side of the rotating block; a spiral groove is formed on the inner wall of the exhaust pipe; the scrapers are evenly arranged and circumferentially distributed on one side of the filter plate; the rotating block is a conical structure with a diameter gradually decreasing towards the direction away from the shielding pipe; and the shielding pipe is a trumpet-shaped structure with a diameter gradually increasing towards the direction away from the exhaust pipe.

[0009] Furthermore, to optimize the airflow distribution of the intake assembly, the gradual contraction of the intake pipe effectively increases the air intake volume. The airflow is also divided by several baffles, ensuring that the airflow is evenly distributed into the fan casing. This avoids efficiency loss and mechanical stress caused by concentrated airflow, thus optimizing the airflow distribution. Simultaneously, as the airflow passes through the expansion pipe, the airflow velocity gradually recovers, ensuring the stability and high efficiency of the oxidation blower. The intake assembly includes an expansion pipe located on the other side of the impeller, with a transition pipe at one end. Several baffles are installed inside the transition pipe, and an intake pipe is located at one end of the transition pipe. The baffles are arranged vertically and crosswise inside the transition pipe.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, through the coordinated arrangement of the support plate, fan housing, exhaust assembly, impeller, motor, and air intake assembly, not only ensures the introduction of oxygen during wet desulfurization, ensuring the generation of stable calcium sulfate and guaranteeing the desulfurization effect of waste gas, but also removes particulate matter and deposits adhering to the surface of the exhaust assembly, ensuring the efficient operation of the oxidation fan, saving cleaning costs and installation complexity, thereby ensuring the adaptability and convenient layout of the oxidation fan, and thus improving the overall efficiency of the oxidation fan.

[0012] 2. Through the exhaust assembly, the airflow is guided by the spiral grooves, causing the airflow to rotate in the direction of the spiral grooves, forming an airflow with angular momentum. When the airflow passes through the rotating blades, the rotating blades are subjected to the impact force of the airflow and rotate, driving the rotating block and rotating shaft to rotate. This allows the scraper and arc rod to scrape the surface of the filter plate and the shielding pipe, removing particulate matter and other deposits generated by the wet desulfurization process from the surface of the filter plate and the shielding pipe. This ensures the air permeability of the filter plate, ensures the efficient operation of the oxidation blower, and saves costs and installation complexity. This ensures the adaptability and convenient layout of the oxidation blower, thereby improving the overall efficiency of the oxidation blower.

[0013] 3. Through the air intake assembly, the air intake volume is effectively increased by the gradual contraction of the air intake pipe. With the airflow being divided by several partition plates, the airflow is ensured to be evenly introduced into the fan casing, avoiding efficiency loss and mechanical stress caused by concentrated airflow and optimizing airflow distribution. At the same time, when the airflow passes through the expansion pipe, the airflow speed is gradually restored, ensuring the stability and high efficiency of the oxidation blower operation.

With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, an oxidation blower for wet desulfurization is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-7 As shown, the oxidation blower for wet desulfurization according to an embodiment of the present utility model includes a support plate 1, a blower housing 2 is provided at the top of the support plate 1, an exhaust assembly 3 is provided through the outer side of the blower housing 2, an impeller 4 is provided through the inside of the blower housing 2, a motor 5 is provided on one side of the impeller 4, and an air intake assembly 6 is provided on the other side of the impeller 4, which penetrates the blower housing 2.

[0027] By utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the support plate 1, the fan housing 2, the exhaust assembly 3, the impeller 4, the motor 5, and the air intake assembly 6, this utility model can not only ensure the introduction of oxygen during the wet desulfurization process and ensure the generation of stable calcium sulfate, thus guaranteeing the desulfurization effect of the exhaust gas, but also remove particulate matter and deposits adhering to the surface of the exhaust assembly 3, ensuring the efficient operation of the oxidation fan, saving cleaning costs and installation complexity, thereby ensuring the adaptability and convenient layout of the oxidation fan, and further improving the overall efficiency of the oxidation fan.

[0028] In one embodiment, the exhaust assembly 3 includes an exhaust pipe 301 extending through the outer side of the fan housing 2. A connecting pipe 302 is provided at the end of the exhaust pipe 301, and a shielding pipe 303 is provided at one end of the connecting pipe 302. A filter plate 304 is provided at the end of the shielding pipe 303 near the exhaust pipe 301. A rotating shaft 305 extends through the middle of the filter plate 304. Several scraper rods 306 connected to the rotating shaft 305 are provided on the side of the filter plate 304 away from the exhaust pipe 301. One end of each scraper rod 306 has an arc-shaped rod 307 that cooperates with the shielding pipe 303. A rotating block 308 connected to the rotating shaft 305 is provided on the other side of the filter plate 304. Several rotating blades 309 are provided on the outer side of the rotating block 308. A spiral groove 310 is formed on the inner wall of the exhaust pipe 301. The scraper rods 306 are evenly arranged and circumferentially distributed on one side of the filter plate 304. The rotating block 308 is positioned to move away from the exhaust pipe 301. The shielding pipe 303 has a tapered structure with a gradually decreasing diameter in the direction of the shielding pipe 303; the shielding pipe 303 has a trumpet-shaped structure with a gradually increasing diameter in the direction away from the exhaust pipe 301; under the guidance of the spiral groove 310, the airflow will rotate in the direction of the spiral groove 310, forming an airflow with angular momentum. When the airflow passes through the rotating blade 309, the rotating blade 309 will be rotated by the impact force of the airflow, driving the rotating block 308 and the rotating shaft 305 to rotate, so that the scraper 306 and the arc rod 307 can scrape the surface of the filter plate 304 and the shielding pipe 303, removing the particulate matter and other deposits generated by the wet desulfurization process that are attached to the surface of the filter plate 304 and the shielding pipe 303, ensuring the air permeability of the filter plate 304, ensuring the efficient operation of the oxidation blower, and saving costs and installation complexity, thereby ensuring the adaptability and convenient layout of the oxidation blower, and thus improving the overall efficiency of the oxidation blower.

[0029] In addition, it should be noted that in order to ensure that the airflow can pass through the filter plate 304 and enter the interior of the wet desulfurization tower, the end of the exhaust pipe 301 away from the fan casing 2 is located inside the wet desulfurization tower. This is existing technology and will not be elaborated on here.

[0030] In addition, it should be noted that, in order to facilitate the maintenance of the exhaust assembly 3, the exhaust pipe 301 and the connecting pipe 302 are connected by threads, which is existing technology and will not be elaborated on here.

[0031] In addition, it should be noted that in order to ensure the rotation of the rotating shaft 305, the filter plate 304 and the rotating shaft 305 are connected by a bearing. This is existing technology and will not be elaborated on here.

[0032] Working principle of exhaust assembly 3: When airflow is discharged from exhaust pipe 301, the airflow will rotate in the direction of spiral groove 310 under the guidance of spiral groove 310, forming an airflow with angular momentum. When the airflow passes through rotating blade 309, rotating blade 309 is rotated by the impact force of the airflow, which drives rotating block 308 and rotating shaft 305 to rotate, so that scraper 306 and arc rod 307 can scrape the surface of filter plate 304 and shielding pipe 303, scraping off the residue attached to filter plate 304 and shielding pipe 303. 3. Particulate matter and other deposits generated during the wet desulfurization process are removed from the surface of the filter plate 304. Under the action of the funnel-shaped structure of the shielding pipe 303, the scraped particulate matter and other deposits can fall into the interior of the wet desulfurization tower under the action of the airflow and the inclined path of the shielding pipe 303. At the same time, the shielding pipe 303 can also shield the filter plate 304 to a certain extent, further reducing the generation of particulate matter and other deposits on the surface of the filter plate 304, greatly ensuring the air permeability of the filter plate 304, so that the airflow can smoothly enter the interior of the wet desulfurization tower and ensure the desulfurization effect.

[0033] In one embodiment, the air intake assembly 6 includes an expansion pipe 601 disposed on the other side of the impeller 4. One end of the expansion pipe 601 is provided with a transition pipe 602. The interior of the transition pipe 602 is provided with a plurality of partition plates 603. One end of the transition pipe 602 is provided with an air intake pipe 604. The partition plates 603 are arranged vertically and crosswise inside the transition pipe 602. Under the gradual contraction of the air intake pipe 604, the intake volume of air is effectively increased. Under the effect of the partition plates 603 dividing the airflow, the airflow is ensured to be evenly introduced into the fan casing 2, avoiding efficiency loss and mechanical stress caused by concentrated airflow, optimizing the airflow distribution. At the same time, when the airflow passes through the expansion pipe 601, the airflow speed is gradually restored, ensuring the stability and high efficiency of the oxidation fan operation.

[0034] In addition, it should be noted that the above-mentioned intake pipe 604 is a trumpet-shaped structure with a diameter that gradually decreases towards the expansion pipe 601.

[0035] In addition, it should be noted that the aforementioned expansion tube 601 is a tapered structure with a diameter that gradually increases towards the direction of the fan casing 2.

[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0037] In practical applications, by starting the motor 5, the rotation of the output shaft of the motor 5 drives the impeller 4 to rotate, causing a negative pressure to be generated inside the fan casing 2. This allows the airflow to enter the fan casing 2 through the air intake assembly 6. Under the continuous rotation of the impeller 4, the airflow is accelerated and compressed, and then enters the exhaust pipe 301. Guided by the spiral groove 310, the airflow rotates in the direction of the spiral groove 310, forming an airflow with angular momentum. Then, it passes through the rotating blade 309, which is rotated by the impact force of the airflow. This causes the scraper 306 to scrape off the particulate matter and other deposits generated by the wet desulfurization process that are attached to the surface of the filter plate 304 and the shielding pipe 303, ensuring the air permeability of the filter plate 304. This allows the airflow to pass smoothly through the filter plate 304 and enter the interior of the wet desulfurization tower, ensuring the desulfurization effect of the exhaust gas (the working principle of the exhaust assembly 3 is as described above).

[0038] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the support plate 1, fan housing 2, exhaust assembly 3, impeller 4, motor 5, and intake assembly 6, not only can oxygen be introduced during the wet desulfurization process to ensure the generation of stable calcium sulfate and guarantee the desulfurization effect of the exhaust gas, but it can also remove particulate matter and deposits adhering to the surface of the exhaust assembly 3, ensuring the efficient operation of the oxidation blower, saving cleaning costs and installation complexity, thereby ensuring the adaptability and convenient layout of the oxidation blower, and thus improving the overall efficiency of the oxidation blower; through the exhaust assembly 3, under the guidance of the spiral groove 310, the airflow will rotate in the direction of the spiral groove 310, forming an airflow with angular momentum. When the airflow passes through the rotating blade 309, the rotating blade 309 will be rotated by the impact force of the airflow, driving the rotating block 308 and the rotating shaft 305 to rotate, causing the scraper to... 306 and the arc-shaped rod 307 can scrape the surface of the filter plate 304 and the shielding pipe 303, removing particulate matter and other deposits generated by the wet desulfurization process from the surface of the filter plate 304 and the shielding pipe 303, ensuring the air permeability of the filter plate 304, ensuring the efficient operation of the oxidation blower, and saving costs and installation complexity, thereby ensuring the adaptability and convenient layout of the oxidation blower, and thus improving the overall efficiency of the oxidation blower; through the air intake component 6, the air intake volume is effectively increased under the gradual contraction of the air intake pipe 604, and under the effect of the airflow segmentation by several partition plates 603, the airflow can be evenly introduced into the blower casing 2, avoiding efficiency loss and mechanical stress caused by concentrated airflow, optimizing the airflow distribution, and at the same time, when the airflow passes through the expansion pipe 601, the airflow velocity is gradually restored, ensuring the stability and high efficiency of the oxidation blower operation.
