Desulfurization component, desulfurization tower and desulfurization method

Abstract

The present application discloses a desulfurization assembly, a desulfurization tower and a desulfurization method, including a mounting part, a plurality of nozzles mounted on the mounting part, a rotating part sleeved on the mounting part, an air intake part fixedly connected to the rotating part, and a fixing part fixedly connected to one end of the mounting part, wherein the mounting part and the fixing part are fixed to each other to prevent the mounting part and the fixing part from falling off the mounting part. After the desulfurizer of the present application is sprayed into the groove, the special shape and angle of the inner wall of the groove enable the desulfurizer to be diverted along the inner wall. During the diversion process, the desulfurizer collides with the inner wall of the groove, thereby generating reflection. The reflection causes the desulfurizer to form a unique atomization zone in the absorption chamber. This atomization zone greatly increases the contact area between the desulfurizer and the flue gas. Compared with traditional desulfurization methods, this large-area contact allows the sulfur dioxide in the flue gas to react more fully with the desulfurizer, thereby significantly improving the reaction efficiency.

Description

Technical Field

[0001] The present application relates to the technical field of flue gas desulfurization, and in particular to a desulfurization component, a desulfurization tower and a desulfurization method. Background Art

[0002] In the current field of energy utilization, coal-fired boilers, as equipment that utilizes thermal energy for heating or power generation, are usually composed of a combustion chamber, a heat exchange system, and a smoke exhaust system.

[0003] During the operation of coal-fired boilers, a large amount of flue gas is generated, which contains a large amount of dust, sulfur dioxide and other pollutants. Therefore, before discharging these flue gases, they need to be absorbed and filtered by a desulfurization tower. At present, wet desulfurization is the most widely used method. The wet desulfurization tower is generally composed of a tower body, a spray system, a demister, a circulating pump, etc. During the desulfurization process, the boiler flue gas enters from the bottom of the tower and fully contacts with the desulfurizer (such as lime water, limestone desulfurizer, etc.) sprayed from the top of the tower. The sulfur dioxide in the flue gas is absorbed and converted into harmless substances such as gypsum through chemical reactions.

[0004] However, the existing desulfurization tower is usually large in size, which may lead to insufficient contact between flue gas and desulfurizer. Although the spray system is equipped with multiple nozzles to cross-spray to form an absorption zone, the absorption effect near the inner wall of the desulfurization tower is still poor. Summary of the invention

[0005] The purpose of the present application is to provide a desulfurization component, a desulfurization tower and a desulfurization method in order to improve the desulfurization effect of the desulfurization tower.

[0006] A desulfurization assembly provided in the present application adopts the following technical solution: comprising a mounting member, a plurality of nozzles mounted on the mounting member, a rotating member sleeved on the mounting member, an air intake member fixedly connected to the rotating member, and a fixing member fixedly connected to one end of the mounting member, wherein the mounting member and the fixing member are fixedly abutted against each other to prevent the mounting member and the fixing member from falling off the mounting member;

[0007] Among them, the rotating part is provided with an annular groove connected with the air inlet, the annular groove surrounds the mounting part, the annular groove and the outer wall of the mounting part enclose an absorption chamber, the nozzle is installed on the mounting part in the absorption chamber, and the nozzle sprays basically vertically on the inner wall of the annular groove.

[0008] By adopting the above technical solution, the spray range of the nozzle is conical, the absorption chamber space is relatively narrow, and basically vertical means that the nozzle sprays vertically / inclined at 0°-10° on the inner wall of the annular groove. The desulfurizer is reflected by the inner wall of the absorption chamber, so that the absorption chamber is filled with the desulfurizer, which increases the contact area between the flue gas and the desulfurizer and improves the reaction efficiency.

[0009] Preferably, the air intake member is provided with an air inlet, and the air intake member is fixedly connected to a first flow guide member, the first flow guide member sucks in smoke and transports it to the absorption chamber through the air inlet, and the rotating member is fixedly connected to a second flow guide member, the first flow guide member and the second flow guide member guide smoke in opposite directions, and the smoke of the second flow guide member is discharged from the rotating member.

[0010] By adopting the above technical solution, after the flue gas enters the air suction groove from the air inlet, the first guide component generates a directional driving force as the air inlet rotates, and quickly guides the flue gas to the absorption chamber in the annular groove. In this process, due to the consistency of the rotation direction, the flow path of the flue gas is more stable, reducing the air flow turbulence and resistance that may be caused by rotation in different directions. At the same time, the second guide component in the air outlet groove is also driven by the rotating part to smoothly discharge the flue gas that has been desulfurized out of the rotating part. This synergistic effect makes the flow of flue gas in the entire desulfurization component like a coherent channel, greatly improving the transmission efficiency of the flue gas.

[0011] Preferably, a groove is provided on the inner wall of the annular groove, the groove track is in a ring shape along the inner wall of the annular groove, the inner walls on both sides of the groove have a slope, and the injection port of the nozzle faces the lowest point of the groove.

[0012] By adopting the above technical solution, the slopes on both sides of the groove have a significant diversion effect. When the nozzle sprays the desulfurizer, part of the desulfurizer will be sprayed directly to the groove on the inner wall of the annular groove. Since the inner walls on both sides of the groove have slopes, these desulfurizers will change their movement direction under the guidance of the slope after contacting the slope. Part of the desulfurizer will return along the slope to the mounting part. This return movement trajectory makes the distribution of the desulfurizer in the absorption chamber more uniform. If there is no diversion effect of the slope, the sprayed desulfurizer may gather in the groove to form a thin stream.

[0013] Preferably, a plurality of adsorption plates are provided in the annular groove, and the plurality of adsorption plates are distributed in an annular shape along the inner wall of the annular groove. When in use, the adsorption plate is located below the nozzle, with one side of the adsorption plate fixed to the inner wall of the annular groove and the other side abutting against the outer wall of the mounting part.

[0014] By adopting the above technical solution, as the adsorption plates rotate, they form a dynamic adsorption area in the annular groove. When the flue gas flows in the annular groove, the adsorption plate can quickly capture the particles therein, and the particles are captured by the adsorption plate. The rotation of the adsorption plate helps to cause these particles to settle. During the rotation process, the particles are accelerated to move to the surface of the adsorption plate by the combined effects of gravity and centrifugal force, and gradually settle down; the atomized water mist will adhere to the surface of the adsorption plate and gradually form droplets. The surface tension of the droplets can adsorb the surrounding particles and fix them on the surface of the droplets. On the other hand, the droplets can continue to react with harmful substances in the flue gas.

[0015] Preferably, the adsorption plate is provided with a first slide groove, a slider is slidably connected in the first slide groove, the slider is fixedly connected with a scraper, the scraper abuts against the surface of the adsorption plate, a plurality of second slide grooves are provided on the inner wall of the annular groove, the trajectory of the second slide groove is parallel to the surface of the adsorption plate, and a third slide groove is provided on the outer surface of the mounting part, and the two ends of the scraper are slidably connected to the second slide groove and the third slide groove respectively.

[0016] By adopting the above technical solution, as the adsorption plate continuously rotates around the mounting part, the scraper will continuously repeat the same motion trajectory within a certain angle range under the restriction and guidance of the third slide groove and the second slide groove. Due to the continuous rotation of the adsorption plate, the scraper will periodically pass through different parts of the adsorption plate, thereby achieving periodic scraping of the surface of the adsorption plate. For example, when the adsorption plate rotates one circle, the scraper may scrape the surface of the adsorption plate once at a specific position. As the adsorption plate continues to rotate, this scraping will be repeated continuously to ensure that the surface of the adsorption plate is always kept clean.

[0017] A desulfurization tower comprises the above-mentioned desulfurization component, a tower body, an inlet flue and an outlet flue both connected to the tower body, a desulfurizer tank, a desulfurizer transportation system, a demisting system, and a power system for driving the desulfurization component to work, wherein the mounting member in the desulfurization component is fixedly installed in the tower body, the air suction slot in the desulfurization component is connected to the inlet flue, the desulfurizer tank is located below the desulfurization component, the desulfurizer transportation system circulates the desulfurizer in the desulfurizer tank to the nozzle in the desulfurization component, and the power system drives the air intake member and the rotating member in the desulfurization component to rotate;

[0018] Wherein, the installation part in the desulfurization component is also provided with a transport flue, and the demisting system is arranged in the transport flue.

[0019] By adopting the above technical solution, the flue gas flow path is optimized and the volume of the tower body is reduced. The absorption chamber is arranged near the inner wall of the tower body, which makes full use of the horizontal space of the tower body and reduces the dependence on the height direction space. After passing through the absorption chamber, the flue gas bypasses the bottom of the desulfurization component and enters the demisting system. This flow path is more compact than the traditional arrangement. The flow distance of the flue gas is shortened, which reduces the energy loss and resistance in the flow process and improves the transmission efficiency of the flue gas.

[0020] Preferably, the power system includes a driven component fixedly connected to the rotating component, a motor, and a baffle fixedly connected to the rotating component, the motor drives the driven component to rotate through gear transmission / belt transmission / chain transmission, and the baffle isolates the smoke.

[0021] By adopting the above technical solution, the baffle fixedly connected to the rotating member plays an important role in isolating the flue gas. During the desulfurization process, the baffle can prevent the flue gas from leaking into the area where the motor and transmission components are located, protecting the motor and transmission system from corrosion and damage by the flue gas.

[0022] A desulfurization method includes the above-mentioned desulfurization tower, and the specific desulfurization steps are as follows:

[0023] Step S1, the motor can drive the air intake member and the rotating member to rotate simultaneously, and the first flow guide member guides the flue gas to flow, so that the flue gas containing sulfur dioxide enters the absorption chamber of the desulfurization tower through the inlet flue;

[0024] Step S2, the desulfurizer transport system delivers the desulfurizer to the nozzle, and the nozzle sprays the desulfurizer to form a desulfurizer mist area in the absorption chamber, and the flue gas and the desulfurizer mist fully contact and react;

[0025] Step S3, the adsorption plate in the annular groove adsorbs impurities, and the scraper can clean the adsorption plate;

[0026] Step S4, the flue gas after desulfurization is defogged by the defog system in the transport flue and then discharged into the atmosphere through the outlet flue;

[0027] By adopting the above technical solution, the desulfurizer transportation system delivers the desulfurizer to the nozzle, and the nozzle sprays the desulfurizer to form a desulfurizer water mist area in the absorption chamber. This atomization spraying method greatly increases the contact area between the desulfurizer and the flue gas, making the chemical reaction more sufficient and rapid. Compared with traditional desulfurization methods, this method can improve the desulfurization efficiency and reduce the amount of desulfurizer used.

[0028] Preferably, the specific principle of forming the desulfurizer water mist area in step S2 is: the nozzle sprays the desulfurizer toward the groove on the inner wall of the annular groove, the desulfurizer is guided and reflected by the inner wall of the groove to form desulfurizer water mist in the absorption chamber, and the rotation of the rotating part causes the reflected water mist to shift, so that the desulfurizer is more evenly distributed in the absorption chamber.

[0029] By adopting the above technical solution, the presence of the groove provides a specific path and direction for the flow of the desulfurizer. When the desulfurizer is sprayed out from the nozzle, it first contacts the inner wall of the groove. The shape and angle of the inner wall of the groove enable the desulfurizer to be guided along the inner wall. During the diversion process, the desulfurizer will collide with the inner wall of the groove, thereby generating reflection; when the rotating part rotates, it will drive the surrounding air and the desulfurizer to move together. Since the reflected water mist is in the absorption chamber, the rotation of the rotating part will cause the reflected water mist to shift. This shift is not irregular, but is driven by the rotating part in a certain trajectory and direction. Specifically, the rotation of the rotating part will generate centrifugal force and airflow, which will act on the reflected water mist, causing it to continuously move and diffuse in the absorption chamber. As the rotating part continues to rotate, the reflected water mist will shift at various positions in the absorption chamber, so that the desulfurizer can be more evenly distributed throughout the absorption chamber.

[0030] Preferably, the specific principle of the adsorption plate in step S3 is as follows: the adsorption plate rotates with the rotating part, and during the rotation of the adsorption plate, the physicalized desulfurizer will adhere to the surface of the adsorption plate to form droplets, and the droplets will adsorb particulate matter in the flue gas.

[0031] By adopting the above technical solution, during the rotation of the adsorption plate, the atomized desulfurizer will adhere to the surface of the adsorption plate. This is because the adsorption plate constantly interacts with the surrounding environment during rotation, and the atomized desulfurizer particles move in the air. When they approach the surface of the adsorption plate, the desulfurizer particles will adhere to its surface because the surface of the adsorption plate usually has a certain adsorption or hydrophilicity. As more desulfurizer particles adhere, droplets are gradually formed; these droplets have the function of adsorbing particulate matter in the flue gas. On the one hand, the surface tension of the droplets can attract the surrounding particulate matter and fix it on the surface of the droplets. When the particulate matter in the flue gas approaches the droplets, it will be adsorbed by the surface tension of the droplets. On the other hand, the desulfurizer components in the droplets may react chemically or physically with the particulate matter, further enhancing the adsorption effect. For example, some particulate matter may react with the chemical components in the desulfurizer to form more stable compounds, which are firmly adsorbed on the droplets.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. In the desulfurization component, the design of the nozzle spraying the desulfurizer toward the groove on the inner wall of the annular groove plays a key role. When the desulfurizer is sprayed toward the groove, the special shape and angle of the inner wall of the groove enable the desulfurizer to be diverted along the inner wall. During the diversion process, the desulfurizer collides with the inner wall of the groove, resulting in reflection. The reflection causes the desulfurizer to form a unique atomization area in the absorption chamber. This atomization area greatly increases the contact area between the desulfurizer and the flue gas. Compared with traditional desulfurization methods, this large-area contact allows the sulfur dioxide in the flue gas to react more fully with the desulfurizer, thereby significantly improving the reaction efficiency.

[0034] 2. Due to the presence of the atomization zone in the desulfurization component, the distribution of the desulfurizer in the absorption chamber is more uniform, avoiding the situation of too much or too little desulfurizer in local areas, and further ensuring the stability and reliability of the desulfurization effect; the adsorption plate in the annular groove can better adsorb impurities and harmful substances in the flue gas under the action of the atomization zone. The atomized desulfurizer adheres to the surface of the adsorption plate to form droplets. These droplets can not only adsorb particulate matter, but also chemically react or physically adsorb with harmful substances in the flue gas, further enhancing the adsorption effect. The setting of the scraper can also clean the adsorption plate more effectively in the environment of the atomization zone, ensuring that the adsorption plate always maintains good adsorption performance;

[0035] 3. For the desulfurization tower, the atomization zone formed by reflection is also of great significance. The optimized flue gas flow path enables the flue gas to fully contact with the desulfurizer in the atomization zone when passing through the absorption chamber. The absorption chamber is arranged on the side of the tower body close to the inner wall, making full use of the lateral space of the tower body, and the existence of the atomization zone makes the contact between the flue gas and the desulfurizer more efficient in a limited space. This design not only reduces the volume of the tower body, but also improves the transmission efficiency of the flue gas. BRIEF DESCRIPTION OF THE DRAWINGS

The nozzle 64 is arranged in the rotating part 62. The rotation of the air inlet part 63 causes the flue gas to be sucked into the rotating part 62. The desulfurizer sprayed by the nozzle 64 in the rotating part 62 can form an atomization zone, which increases the contact area between the flue gas and the atomizer and improves the desulfurization effect. The desulfurized flue gas will be discharged from the rotating part 62. In this way, the desulfurization effect and the desulfurization rate can be controlled by controlling the rotation speed of the rotating part 62 and the air inlet part 63.

[0050] refer to Figure 2The mounting member 61 includes a shaft portion 611 and a limiting portion 616 arranged on the shaft portion 611. The air intake member 63 and the rotating member 62 are both sleeved on the shaft portion 611. The other end of the shaft portion 611 is connected to a fixing member 612 by a thread. The air intake frame and the rotating member 62 are restricted on the shaft portion 611 by the tight contact between the limiting portion 616 and the fixing member 612. The air intake member 63 and the rotating member 62 can rotate on the shaft portion 611. A plurality of nozzles 64 are evenly distributed around the shaft portion 611. A first channel 614 connecting the nozzle 64 is provided on the shaft portion 611. The first channel 614 is externally connected to the desulfurizer transport system 8. The desulfurizer in the desulfurizer transport system 8 is transported to the nozzle 64 through the first channel 614. A third slide groove 613 is provided on the surface of the shaft portion 611. The trajectory of the third slide groove 613 surrounds the surface of the shaft portion 611. The third slide groove 613 has a stationary section 6132 and a driving section 6131.

[0051] refer to Figure 3 The air inlet member 63 includes a first annular plate 631, a second annular plate 632 and a first support member 633. The first annular plate 631 is parallel to the second annular plate 632. Both ends of the first support member 633 are fixedly connected to the first annular plate 631 and the second annular plate 632 respectively. The first support member 633 divides the gap between the first annular plate 631 and the second annular plate 632 into a first groove 636 and a second groove 637. The second groove 637 is close to the inner side of the first annular plate 631, and the first groove 636 is far away from the inner side of the first annular plate 631. The first support member 633 is provided with a Air inlet 635; in Example 1, the first support member 633 takes an annular cylinder as an example, and can also be a plurality of support rods and a plurality of support blocks. A plurality of through holes are opened on the annular cylinder as the air inlet 635. If the rods / blocks are used as the support frame, the gap between two adjacent rods / blocks is the air inlet 635; a first flow guide component 634 is fixedly connected in the first groove 636. The first flow guide component 634 is used to inhale smoke. The first flow guide component 634 includes a plurality of inclined blades. The edges of the blades are twisted and bent. Plates are fixedly connected on both sides of the blades. When the air inlet member 63 rotates, the blades rotate circumferentially to generate suction to inhale the smoke.

[0052] refer to Figure 4The rotating member 62 includes a third annular plate 621, a fourth annular plate 622, a fifth annular plate 624, a plurality of support columns 625 respectively connected to the fourth annular plate 622 and the fifth annular plate 624, and a second support member 623. The third annular plate 621 is parallel to the second annular plate 632. Both ends of the second support member 623 are respectively fixedly connected to the third annular plate 621 and the fourth annular plate 622. The second support member 623 is located between the inner ring and the outer ring of the third annular plate 621 and the fourth annular plate 622. The third annular plate 621, the fourth annular plate 622, and the fifth annular plate 624 are all sleeved on the shaft 611. In Example 1, the second support plate is an annular cylinder as an example, and can also be a multi-faceted cylindrical cylinder. The inner rings of the third annular plate 621, the fourth annular plate 622, and the second support member 623 are The side is surrounded by an annular groove 6288, and the annular groove 6288 and the shaft 611 are surrounded by an absorption chamber 628; the third annular plate 621 and the fourth annular plate 622 are both provided with a grille 627, the grille 627 is connected with the annular groove 6288, and the grille 627 of the third support is connected with the second groove 637. When the grille 627 rotates, the grille 627 can stir and guide the flue gas, so that the flue gas is more evenly distributed in the absorption chamber 628 after passing through the grille 627; a second guide component 626 is fixedly connected between the fourth annular plate 622 and the fifth annular plate 624, and the first guide component 634 is different from the second guide component 626 in the inclination direction of the blade and the curvature bending direction. When the rotating member 62 rotates, the second guide component discharges the flue gas in the rotating member 62.

[0053] refer to Figure 5 and Figure 6 A groove 6281 is provided on the second support member 623. The trajectory of the groove 6281 is in a ring shape along the inner wall of the annular groove 6288. The inner walls on both sides of the groove 6281 have a slope. In the embodiment, the slope takes an inclined surface as an example, and can also be an arc-shaped surface. The injection port of the nozzle 64 faces the lowest point of the groove 6281. When the nozzle 64 sprays the desulfurizer, the desulfurizer is reflected along the inclined surface to form a water film, so that the desulfurizer is more evenly atomized in the absorption chamber 628. If there is no guiding effect of the slope, the sprayed desulfurizer may gather in the groove 6281 to form a thin stream; when the rotating member 62 rotates, the desulfurizer obtains rotational acceleration at the moment of contacting the groove 6281, and when the desulfurizer is reflected, an inclined water film is obtained, thereby increasing the coverage area.

[0054] refer to Figure 7, a plurality of adsorption plates 6282 are also arranged in the annular groove 6288, and the plurality of adsorption plates 6282 are distributed in an annular shape along the inner wall of the annular groove 6288. When in use, the adsorption plates 6282 are located below the nozzle 64. In Example 1, the adsorption plates 6282 are arranged obliquely in the annular groove 6288. As the adsorption plates 6282 rotate, they form a dynamic adsorption area in the annular groove 6288. When the flue gas flows in the annular groove 6288, the adsorption plates 6282 can quickly capture the particles therein, and the particles are captured by the adsorption plates 6282. The rotation of the adsorption plates 6282 helps to cause the particles to settle. During the rotation process, the particles are subjected to the superposition of gravity and centrifugal force, and accelerate to move to the surface of the adsorption plates 6282 and gradually settle down; the atomized water mist will adhere to the surface of the adsorption plates 6282 and gradually form droplets. The surface tension of the droplets can adsorb the surrounding particles and fix them on the surface of the droplets. On the other hand, the droplets can continue to react with harmful substances in the flue gas. A first slide groove 6287 is also provided on the adsorption plate 6282. A slider 6286 is slidably connected in the first slide groove 6287. A scraper 6285 is fixedly connected to the slider 6286. The scraper 6285 abuts against the surface of the adsorption plate 6282. A plurality of second slide grooves 6283 are provided on the inner wall of the annular groove 6288. The tracks of the second slide grooves 6283 are parallel to the surface of the adsorption plate 6282. Rollers 6284 are provided at both ends of the scraper 6285. The rollers 6284 are located in the second slide grooves 6283 and the third slide grooves 613 and roll. When the rollers 6284 are in the stationary section 6132, the scraper 6285 is stationary on the surface of the adsorption plate 6282. When the rollers 6284 are in the driving section 6131, the scraper 6285 moves under the action of the second slide grooves 6283 and the driving end.

[0055] refer to Figure 8 , the principle of a desulfurization component 6 is as follows. First, when the air intake member 63 rotates under the drive of the power system 9, the blades in the first guide member 634 that are tilted and have twisted and bent edges begin to rotate circumferentially. The unique shape and tilt angle of the blades enable them to generate strong suction during rotation, thereby smoothly inhaling the sulfur-containing flue gas. The plates on both sides of the blades further enhance the flow-guiding effect, ensuring that the flue gas can enter the air intake member 63 stably and efficiently. Then, the flue gas passes through the air inlet 635 on the first support member 633 and enters the first groove 636 and the second groove 637. Among them, the second groove 637 is close to the inner side of the first annular plate 631. Under the guidance of the first guide member 634, the flue gas mainly enters the second groove 637 to prepare for subsequent entry into the rotating member 62.

[0056] Subsequently, the desulfurizing agent transport system 8 transports the desulfurizing agent to the nozzle 64. The nozzle 64 is disposed in the rotating member 62 and connected to the desulfurizing agent transport system 8 through the first channel 614. The nozzle 64 sprays the desulfurizing agent in atomization to form an atomization area in the rotating member 62. The rotation of the rotating member 62 cooperates with the spraying angle of the nozzle 64. When the nozzle 64 sprays the desulfurizing agent, the desulfurizing agent will be directed toward the lowest point of the groove 6281 on the second support member 623. The inner walls on both sides of the groove 6281 have a slope. Whether it is an inclined surface or an arc-shaped surface, the desulfurizing agent can be reflected along the slope to form a water film, so that the desulfurizing agent is more evenly atomized in the absorption chamber 628. If there is no diversion effect of the slope, the sprayed desulfurizing agent may gather in the groove 6281 to form a thin stream. Moreover, when the rotating member 62 rotates, the desulfurizing agent will obtain a rotational acceleration at the moment of contacting the groove 6281. When the desulfurizing agent is reflected, an inclined water film will be formed to increase the coverage area. In this way, the flue gas and the atomized desulfurizer can fully contact each other in the absorption chamber 628, undergo a chemical reaction, and effectively remove harmful substances such as sulfur dioxide in the flue gas.

[0057] At the same time, the grilles 627 on the third annular plate 621 and the fourth annular plate 622 are connected to the annular groove 6288, and the grille 627 of the third annular plate 621 is connected to the second groove 637. When the grille 627 rotates with the rotating member 62, it can play a role in stirring and guiding the flue gas, so that the flue gas is more evenly distributed in the absorption chamber 628 after passing through the grille 627. This uniform distribution ensures that the flue gas can fully contact with the atomized desulfurizer, greatly improving the desulfurization effect.

[0058] In addition, the adsorption plate 6282 is distributed in a ring shape along the inner wall of the annular groove 6288, and is located below the nozzle 64 when in use. The adsorption plate 6282 is tilted in the annular groove 6288, and as the adsorption plate 6282 rotates, a dynamic adsorption area is formed in the annular groove 6288. When the flue gas flows in the annular groove 6288, the adsorption plate 6282 can quickly capture the particles therein. After the particles are captured by the adsorption plate 6282, they are accelerated to move to the surface of the adsorption plate 6282 under the combined effect of gravity and centrifugal force, and gradually settle down. The atomized water mist will adhere to the surface of the adsorption plate 6282 and gradually form droplets. The surface tension of the droplets can adsorb the surrounding particles and fix them on the surface of the droplets. At the same time, the droplets can continue to react with harmful substances in the flue gas to further purify the flue gas.

[0059] Finally, the smoke is discharged through the first guide component 634.

The flue gas first enters the desulfurization tower through the inlet flue 2, and is sucked into the absorption chamber 628 through the first guide component 634. The absorption chamber 628 surrounds the transport flue 615, that is, the flue gas first flows downward near the wall of the desulfurization tower, and finally flows upward at the center of the desulfurization tower wall. This greatly optimizes the flue gas flow path and reduces the volume of the tower body 1, makes full use of the lateral space of the tower body 1, and reduces the dependence on the height direction space.

[0061] refer to Fig.10 The power system 9 includes a driven component 92 fixedly connected to the rotating component 62, a motor 91, and a baffle 93 fixedly connected to the rotating component 62. The driven component 92 in Example 2 is a pulley, and can also be a sprocket, gear, etc. The motor 91 drives the driven component 92 to rotate through a belt, and the baffle 93 isolates the smoke.

[0062] Example 3, a desulfurization method, comprising the above-mentioned desulfurization tower, the specific desulfurization steps are as follows:

[0063] Step S1, the motor 91 can drive the air inlet member 63 and the rotating member 62 to rotate simultaneously, and the first fan blade guides the flue gas flow, so that the flue gas containing sulfur dioxide enters the absorption chamber 628 of the desulfurization tower through the inlet flue 2;

[0064] Step S2, the desulfurizer transport system 8 delivers the desulfurizer to the nozzle 64, and the nozzle 64 sprays the desulfurizer to form a desulfurizer mist area in the absorption chamber 628, and the flue gas and the desulfurizer mist fully contact and react;

[0065] Step S3, the adsorption plate 6282 in the annular groove 6288 adsorbs impurities, and the scraper 6285 can clean the adsorption plate 6282;

[0066] Step S4: the flue gas after desulfurization passes through the demisting system 5 and the electrostatic dust removal system 4 in the transport flue 615 and is discharged into the atmosphere through the outlet flue 7.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
