Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization and dust reduction, and particularly to a deep dust reduction device inside a desulfurization tower. Background Art

[0002] In the prior art, such as the technology disclosed in Publication No. CN112138494A, a large number of static electricity balls are used in the corresponding swirling space. Through the mutual friction and impact of the static electricity balls, adsorbed static electricity is formed to adsorb the dust in the passing gas. However, in the actual application process, the moving state of the static electricity balls is uncontrollable, the positions of the static electricity balls are random, and the size of the air flow formed between the static electricity balls through the gaps cannot be guaranteed. Therefore, the purification ability is also affected by corresponding uncertainties. In addition, a large number of static electricity balls are restricted by the baffle plate itself. If the air flow is small, the static electricity balls may be at the bottom of their moving area, resulting in relatively less friction. If the passing air flow is large, all the static electricity balls may rise and be intercepted by the baffle plate, or stuck in the gaps of the corresponding clamping baffle plate, and their movement is restricted. Similarly, the probability of their mutual friction and movement will also decrease, and it is impossible to achieve a relatively strong adsorption adjustment effect for the corresponding air flow rate and quality. Even external auxiliary electrodes are still required to ensure the purification and dust removal effect. Summary of the Invention

Detailed implementation manners

[0030] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific features in the embodiments of this specification and the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. Without conflict, the technical features in the embodiments of this specification and the embodiments can be combined with each other.

[0031] In this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element. The term "more than two" includes two or more than two.

[0032] In the prior art, a large number of electrostatic balls are used in the corresponding swirling space. Through the mutual friction and impact of the electrostatic balls, adsorbed static electricity is formed to adsorb dust in the passing gas. However, in the actual application process, the movement state of the electrostatic balls cannot be controlled, the positions of the electrostatic balls are random, and the size of the air flow gaps formed between the electrostatic balls cannot be guaranteed. Therefore, the purification ability is also affected by corresponding uncertainties. In addition, a large number of electrostatic balls are restricted by baffles themselves. If the air flow is small, the electrostatic balls may be at the bottom of their activity area, resulting in relatively less friction. If the passing air flow is large, all the electrostatic balls may rise and be intercepted by the baffle, or stuck in the gaps of the corresponding clamping baffles, and their activities are restricted. Similarly, the probability of their mutual friction and movement will also decrease, and it is impossible to achieve a relatively strong adsorption adjustment effect for the corresponding air flow rate and quality. Even the participation of external auxiliary electrodes is still required to ensure the purification and dust removal effect.

[0033] In view of this, the embodiment of the present application provides a deep dust reduction device in a desulfurization tower, mainly aiming to solve the problem that the friction and movement of electrostatic balls are unstable, and it is impossible to achieve a relatively strong adsorption adjustment effect for the corresponding air flow rate and quality.

[0034] Please refer to Figures 1 to 9 As shown in the figure, the embodiment of the present application provides a deep dust reduction device in a desulfurization tower, including a swirling cylinder 10 placed in the desulfurization tower, and further including: a desulfurization spraying mechanism 20, a central shaft 30, an adsorption and dust removal mechanism 40, and a guiding mechanism 50;

[0035] The desulfurization spraying mechanism 20 is arranged on the central shaft 30 in the desulfurization tower and at the middle position of the swirling cylinder 10; the adsorption and dust removal mechanism 40 is arranged in the inner cavity of the swirling cylinder 10 and below the desulfurization spraying mechanism 20; the guiding mechanism 50 is arranged below the adsorption and dust removal mechanism 40; wherein, the adsorption and dust removal mechanism 40 includes a plurality of slightly wet electrostatic balls 44, and all the slightly wet electrostatic balls 44 are hoisted at the same height in the swirling cylinder 10. The interval arrangement between the hoisted slightly wet electrostatic balls 44 is more uniform, so a more uniform air flow passing gap is formed. At the same time, the slightly wet electrostatic balls 44 designed to be hoisted are hardly blown by the air flow to the top of the inner cavity of the swirling cylinder 10, and at least one group of slightly wet electrostatic ball moving groups with non-fixed hoisting point positions is included in the plurality of slightly wet electrostatic balls 44.

[0036] In the deep dust removal device in the desulfurization tower provided in this application, the desulfurization spray mechanism 20 is located on the central axis 30 of the desulfurization tower and is arranged in the middle of the cyclone cylinder 10. Its main function is to spray desulfurization liquid to conduct preliminary desulfurization treatment on the gas. Additionally, it can increase the humidity of the gas, providing favorable conditions for subsequent dust removal. At the same time, it also has the function of cleaning the surface of the slightly wet electrostatic balls 44. The cyclone cylinder 10 guides the gas to form a rotating airflow, enhancing the contact effect between the gas and the adsorption dust removal mechanism 40 inside the device. The adsorption dust removal mechanism 40 is arranged in the inner cavity of the cyclone cylinder 10 and rotates itself through contact with the rotating airflow. The core of the adsorption dust removal mechanism 40 is multiple slightly wet electrostatic balls 44. The slightly wet electrostatic balls 44 can better adsorb charged dust particles in a wet state. In particular, at least one group of slightly wet electrostatic balls 44 forms a moving group, and the position of its hoisting point is not fixed, enabling this group of slightly wet electrostatic balls 44 to actively change their positions during rotation as the airflow changes. During rotation, through the relative movement between the moving group of slightly wet electrostatic balls and the fixed slightly wet electrostatic balls 44, the friction impact is increased, thereby continuously and effectively generating adsorption static electricity and enhancing the adsorption capacity for dust in the gas. The guiding mechanism 50 is located below the adsorption dust removal mechanism 40 and is responsible for guiding the airflow to form a swirling flow through.

[0037] Overall, this device realizes efficient deep dust removal of the gas in the desulfurization tower through the preliminary treatment of the desulfurization spray mechanism 20, the airflow guidance of the cyclone cylinder 10, the adsorption of the adsorption dust removal mechanism 40, and the swirling flow guidance drive of the guiding mechanism 50. Without an external auxiliary electrode, it can automatically adjust the adsorption effect according to the gas flow rate, improving the dust removal efficiency and stability.

[0038] As Figure 1 and Figure 3 shown, in some examples, further, the desulfurization spray mechanism 20 includes: a spray main pipe 21 and multiple-stage spray branch pipes 22. The multiple-stage spray branch pipes 22 are horizontally arranged in the desulfurization tower from the inside to the outside in sequence. Multiple spray branch pipes 22 are connected in communication. The bottom end of each spray branch pipe 22 is provided with a spray head; one end of the spray main pipe 21 extends to the outside of the desulfurization tower, and the other end is connected to the spray branch pipes 22.

[0039] In the desulfurization spray mechanism 20 provided in this example, the spray main pipe 21 serves as the main channel for liquid transportation. One end of the spray main pipe 21 extends to the outside of the desulfurization tower to facilitate connection to an external liquid source, such as a desulfurization liquid storage tank, and the other end is connected to a multi-stage spray branch pipe 22 arranged in the desulfurization tower to ensure that the desulfurization liquid can be stably transported to each spray point. The multi-stage spray branch pipes 22 are arranged horizontally from the inside to the outside in sequence to form a multi-level spray network. Each spray branch pipe 22 is interconnected to ensure that the desulfurization liquid is evenly distributed. A spray head is provided at the bottom end of each spray branch pipe 22. Through the spray head, the desulfurization liquid is fully in contact with the rising gas to achieve efficient desulfurization and preliminary dust removal, which can effectively absorb the sulfur in the gas and provide a moist environment for the subsequent adsorption dust removal mechanism 40 to promote the adsorption of dust by the slightly wet electric ball 44. Through the multi-stage and multi-point spray arrangement, the comprehensive effect of desulfurization and dust removal is ensured.

[0040] like Figures 1 to 4 As shown, in some examples, further, the central axis 30 includes an upper fixed axis 31 and a lower fixed axis 32, wherein the adsorption and dust removal mechanism 40 is rotatably sleeved on the outer side of the outer wall of the bottom end of the upper fixed axis 31, the lower half of the adsorption and dust removal mechanism 40 is rotatably connected to the top end of the lower fixed axis 32, and the guide mechanism 50 is fixedly sleeved on the outer wall of the lower fixed axis 32.

[0041] In the deep dust removal device in the desulfurization tower provided in this example, the central axis 30 is composed of an upper fixed axis 31 and a lower fixed axis 32, which constitute the middle support structure of the device. The adsorption dust removal mechanism 40 is sleeved on the outer wall of the bottom end of the upper fixed axis 31 and can rotate relative to it, so that the adsorption dust removal mechanism 40 can continue to rotate under the drive of the airflow and make the slightly wet electric ball 44 inside it fully contact with the rising airflow. At the same time, it can also increase the relative movement between the slightly wet electric balls 44, generate effective friction, and thus improve the electrostatic adsorption efficiency. The lower half of the adsorption dust removal mechanism 40 is rotatably connected to the top of the lower fixed axis 32. This two-point rotation connection method further enhances the stability of the mechanism, ensuring that it can still maintain an effective adsorption state when the airflow changes; the guide mechanism 50 is fixedly sleeved on the outer wall of the lower fixed axis 32, and does not rotate during the operation of the device, providing a spiral guide path for the rising airflow.

[0042] like Figure 7 As shown, in some examples, further, a plurality of driving protrusions 311 distributed in a horizontal circle are provided on the outer wall of the bottom end of the upper fixed shaft 31, and each driving protrusion 311 is provided with inclined or arc-shaped transition edges at both ends in the horizontal direction, and each driving protrusion 311 can contact with the slightly wet electric ball moving group to achieve relative motion friction between the slightly wet electric ball 44 in the slightly wet electric ball moving group and the remaining slightly wet electric balls 44.

[0043] In this example, further, on the outer wall of the bottom end of the upper fixed shaft 31, a plurality of driving bumps 311 distributed circumferentially in the horizontal direction are provided, which are structures for driving the micro-wet electrostatic ball moving group to generate relative movement; both ends of each driving bump 311 in the horizontal direction adopt inclined or arc-shaped transition edges, which not only reduce the impact force when the bump contacts the micro-wet electrostatic ball moving group, but also ensure the smooth and continuous contact effect, and reduce the rotational resistance of the overall adsorption dust removal mechanism 40 on the central shaft 30.

[0044] When the gas passes through the desulfurization tower, the micro-wet electrostatic ball moving group will come into contact with the driving bumps 311 under the drive of the air flow; due to the existence of the driving bumps 311, the micro-wet electrostatic balls 44 in the micro-wet electrostatic ball moving group will be pushed, and relative movement friction will be generated with the surrounding fixed or relatively less moving electrostatic balls; the frictional movement not only increases the contact frequency and strength between the electrostatic balls, promotes the update of the charge distribution on the surface of the electrostatic balls, thereby enhancing the electrostatic adsorption effect; at the same time, the circumferential distribution design of the driving bumps 311 enables the micro-wet electrostatic ball moving group to be continuously and evenly driven under the action of the swirling air flow, ensuring the stability and high efficiency of the dust removal efficiency; through the setting of this example, the device realizes the active drive of the micro-wet electrostatic ball moving group, and without an external power source, it can automatically adjust the movement state of the electrostatic balls according to the air flow conditions, improving the dust removal efficiency and the adaptive ability of the device.

[0045] As Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 shown, in some examples, further, the adsorption dust removal mechanism 40 includes: a hoisting frame 41, a plurality of connecting plates 42, a hoisting part 43 and a gas storage container 45. The hoisting frame 41 is rotatably sleeved on the bottom end of the upper fixed shaft 31 and synchronously sleeved outside all the driving bumps 311. The hoisting frame 41 can rotate along the central axis of the swirl cylinder 10; a plurality of connecting plates 42 are arranged in the direction from the center to the outside and are respectively arranged in a plurality of spaced areas of the hoisting frame 41; the hoisting part 43 is fixedly hoisted at the bottom end of the connecting plate 42; a suspended micro-wet electrostatic ball 44 is connected to the bottom end of each hoisting part 43; the gas storage container 45 is fixedly arranged in the middle of the hoisting frame 41 and is located between the upper fixed shaft 31 and the lower fixed shaft 32. A connected pipeline 415 is provided between the gas storage container 45 and the micro-wet electrostatic ball moving group; a control valve 46 is arranged at the outlet at the bottom end of the gas storage container 45.

[0046] In the adsorption and dust removal mechanism 40 provided in this example, the lifting frame 41 is rotatably sleeved on the bottom end of the upper fixed shaft 31 and surrounds all the driving bumps 311, and can rotate along the central axis of the cyclone cylinder 10 under the action of the air flow and the driving bumps 311; a plurality of connecting plates 42 are arranged from the center to the outside direction and are respectively arranged in a plurality of spaced areas of the lifting frame 41, providing a stable support platform for the lifting part 43; the lifting part 43 includes a flexible material, and the lifting part 43 of the flexible material and its lower end are connected to the slightly wet electric balls 44 in a suspended state, so that the slightly wet electric balls 44 can swing freely and rub against each other in the air flow to generate static electricity to adsorb dust; the gas storage container 45 is arranged in the middle of the lifting frame 41, between the upper fixed shaft 31 and the lower fixed shaft 32, and is connected to the slightly wet electric ball moving group through a pipeline 415, and by means of the moving power of the slightly wet electric ball moving group, the gas collection function is realized at the same time, and the collected gas can have various uses in this device, such as being used as clean air or impact gas to clean the slightly wet electric balls 44 or impact the slightly wet electric balls 44 to increase the friction effect to keep the surface of the slightly wet electric balls 44 clean and ensure the static electricity adsorption ability; the control valve 46 is arranged at the bottom outlet of the gas storage container 45, and the position where the control valve 46 is located is the air outlet of the gas storage container 45. The control valve 46 is used to control the release of gas at an appropriate time. For example, when it is necessary to clean the surface of the slightly wet electric balls 44 or increase the friction between the slightly wet electric balls 44 to improve the dust removal and adsorption effect, to ensure that the slightly wet electric balls 44 reasonably adjust their own adsorption ability according to the corresponding working state requirements. A sealing bearing is sleeved on the outer diameter side of the control valve 46, and the lower fixed shaft 32 is sleeved on the outer wall of the sealing bearing. Even after the lower fixed shaft 32 rotates, a good sealing state can be maintained between the lower fixed shaft 32 and the control valve 46. After the control valve 46 is opened, the gas is sent out through the air flow channel arranged in the lower fixed shaft 32.

[0047] When the air flow passes through the desulfurization tower, the lifting frame 41 rotates under the action of the air flow guiding force in the guiding mechanism 50, driving the connecting plate 42 and the lifting part 43 to move together, so that the slightly wet electric balls 44 rub and collide with each other in the air flow to generate static electricity and adsorb dust; at the same time, the gas storage container 45 supplies the required cleaning or impact gas to the slightly wet electric balls 44 through a gas pipeline, and the control valve 46 adjusts the gas supply according to actual needs; optimizing the static electricity adsorption performance of the electric balls and improving the dust removal efficiency.

[0048] In some examples, further, the control valve 46 is connected to a controller and a pressure sensor (not shown in the figure) located inside the gas storage container 45. The pressure sensor is used to obtain the air pressure in the gas storage container 45 in real time. The controller obtains the pressure value of the pressure sensor. The pressure sensor is provided with a high pressure threshold and a low pressure threshold. When the corresponding high pressure threshold and low pressure threshold are reached in the gas storage container 45, the controller controls the opening and closing of the control valve 46 accordingly.

[0049] In this example, specifically, the control valve 46, the controller, and the pressure sensor inside the gas storage container 45 jointly maintain the control function of the air pressure inside the gas storage container 45. The gas storage container 45 continuously receives gas replenishment from the slightly wet electric ball moving group, and the air pressure inside the gas storage container 45 continuously increases. The pressure sensor real-time monitors the air pressure in the gas storage container 45 and transmits the pressure data to the controller. After receiving the signal from the pressure sensor, the controller compares it with the preset high-pressure threshold and low-pressure threshold. When the air pressure inside the gas storage container 45 is higher than the high-pressure threshold, the controller instructs the control valve 46 to open, releasing all or part of the gas to reduce the air pressure. The gas finally outputs through the guiding mechanism 50 and acts on the surface of the slightly wet electric ball 44, realizing the cleaning and impact disturbance functions on the surface of the corresponding slightly wet electric ball 44. On the contrary, when the release is completed and the air pressure is lower than the low-pressure threshold, the controller instructs the control valve 46 to close, and continues to receive the gas replenishment provided by the movement of the slightly wet electric ball moving group to increase the air pressure. Therefore, this example ensures that the air pressure inside the gas storage container 45 always remains within an appropriate range, and makes the slightly wet electric ball 44 always in a good electrostatic adsorption state. On the one hand, the surface of the slightly wet electric ball 44 is clean enough, with a stronger adsorption effect. At the same time, through the impact of the gas on the slightly wet electric ball 44, the friction between the slightly wet electric balls 44 is increased, enhancing the electrostatic adsorption effect between all the slightly wet electric balls 44.

[0050] In addition, the controller provided in this example can also accept the active control of the staff, and transmit the corresponding control instructions to the controller by means of wired or wireless communication signal transmission. The controller, according to the corresponding instructions of the staff, opens or closes the control valve 46 at an appropriate time.

[0051] As Figures 2 to 5 shown, in some examples, further, the guiding mechanism 50 includes: a plurality of intercepting plates 51, a plurality of guiding vanes 52, several jet nozzles 53, and a central collar 54. The plurality of intercepting plates 51 are fixedly installed equidistantly along the circumferential direction in the lower half inner cavity of the cyclone cylinder 10. The intercepting plates 51 are used to intercept the airflow to form a non-impact area. The plurality of guiding vanes 52 are fixedly installed equidistantly along the circumferential direction in the lower half inner cavity of the cyclone cylinder 10 and are arranged alternately with the intercepting plates 51. An airflow impact gap is provided between the guiding vanes 52 and the intercepting plates 51. Several jet nozzles 53 are fixedly arranged at the top of the intercepting plates 51 and are oriented towards the slightly wet electric ball 44. Each jet nozzle 53 is communicated with the outlet at the bottom end of the gas storage container 45 through an airflow channel arranged inside the lower fixed shaft 32. The side wall of the central collar 54 is fixedly connected to the inner ends of all the intercepting plates 51. The inner wall of the central collar 54 is fixedly sleeved on the outer wall of the lower fixed shaft 32. The top end of the lower fixed shaft 32 is rotatably sleeved outside the outlet of the control valve 46.

[0052] In the guiding mechanism 50 provided in this example, a plurality of intercepting plates 51 are fixedly arranged at equal intervals in the circumferential direction in the lower half inner cavity of the cyclone cylinder 10. The intercepting plates 51 can be horizontally arranged, and their main function is to intercept the airflow to form a non-impact area. The slightly wet electric balls 44 above this area are less directly impacted by the airflow; at the same time, a plurality of guiding vanes 52 are also arranged alternately with the intercepting plates 51 to form an airflow impact gap therebetween. This design not only ensures the passage of the airflow but also makes the airflow rotate when passing through, enhancing the contact effect between the airflow and the electric balls; thus, during the rotation of the overall adsorption and dust removal mechanism 40, all the slightly wet electric balls 44 connected below it will intermittently pass through the non-impact area and the airflow impact gap. Therefore, during the rotation of all the slightly wet electric balls 44, the spheres continuously undergo the cycle of impact and non-impact states, causing all the slightly wet electric balls 44 to experience significant shaking and friction. When the gas passes through the intervals between the spheres, a more uniform and powerful adsorption effect is obtained.

[0053] In addition, several jet heads 53 provided in this example are oriented towards the slightly wet electric balls 44. The jet heads 53 are connected to the outlet at the bottom end of the gas storage container 45 to provide the gas required for cleaning and impacting the slightly wet electric balls 44, and the slightly wet electric balls 44 are cleaned by jetting the airflow to maintain their electrostatic adsorption performance.

[0054] As Figure 3 、 Figure 6 、 Figure 7 and Figure 8 shown, in some examples, furthermore, the slightly wet electric ball moving group is arranged on the lifting frame 41. The slightly wet electric ball moving group includes: a slider 411, a piston head 412, an air chamber 413, a spring 414, and a pipe 415. The slider 411 is slidably arranged in the inner wall of the bottom end surface of the lifting frame 41, and a plurality of lifting parts 43 are connected to the bottom end of the slider 411; the air chamber 413 is opened in the inner cavity of the end part at the outermost horizontal end of all or part of the lifting frame 41; the piston head 412 is fixedly arranged at the outer end of the slider 411, and the piston head 412 is movably arranged in the air chamber 413; the spring 414 is arranged in the inner cavity of the air chamber 413 outside the piston head 412; one end of the pipe 415 is connected to the end of the air chamber 413 far from the slider 411, the other end of the pipe 415 is connected to the gas storage container 45, and a one-way valve is arranged on the pipe 415.

[0055] In this example, it should be noted that the hoisting structure of the slightly wet electric balls 44 in the slightly wet electric ball moving group is different from that of the remaining slightly wet electric balls 44. The slightly wet electric balls 44 in the slightly wet electric ball moving group are hoisted on the slider 411. A spring 414 is arranged at the inner end of the slider 411, and a piston head 412 is arranged at the outer end. Under the thrust of the spring 414, the slider 411 always moves towards the driving convex block 311. During this movement process, since the overall hoisting frame 41 rotates, the inner end of the slider 411 will also continuously pass by and move away from the driving convex block 311. Therefore, during the rotation of the overall hoisting frame 41, the position of the slider 411 is forced to change continuously. Due to the continuous change of the position of the overall slider 411, the position of the slightly wet electric ball 44 connected below the slider 411 also correspondingly shakes. The shaking slightly wet electric ball 44 and the surrounding slightly wet electric balls 44 form relative motion friction, and finally the effect of increasing the adsorption force is achieved.

[0056] The working process of gas replenishment in the gas storage container 45: In the above working process, the position of the slider 411 changes continuously. A piston head 412 is also arranged at the end of the slider 411, and a one-way valve is arranged on the piston head 412, so as to push the air continuously entering the air chamber 413 into the gas storage container 45 through the pipeline 415, realizing the storage of high-pressure gas.

[0057] As Figure 9 shown, in some examples, further, the hoisting part 43 includes: an upper flexible section 431, a middle straight rod 432, and a lower flexible section 433, which are connected in sequence from top to bottom. Among them, the upper flexible section 431 is connected to the slider 411 or the hoisting frame 41, and the lower flexible section 433 is connected to the slightly wet electric ball 44.

[0058] In the hoisting part 43 provided in this example, the upper flexible section 431, the middle straight rod 432, and the lower flexible section 433 are connected in sequence from top to bottom, forming a flexible hoisting structure connecting the hoisting frame 41 and the slightly wet electric ball 44; the upper flexible section 431 is connected to the slider 411 or the hoisting frame 41 and can swing with the rotation of the hoisting frame 41; the middle straight rod 432 serves as a rigid support connecting the upper and lower flexible sections 433 to ensure the overall stability of the hoisting part 43, without generating a relatively complex movement trajectory and avoiding the situation of mutual contact and entanglement between multiple hoisting parts 43; the lower flexible section 433 is connected to the slightly wet electric ball 44, and also utilizes its flexible characteristics to enable the electric ball to maintain a certain degree of freedom in the air flow and better adapt to the changes in the air flow.

[0059] In some examples, further, an air quality monitoring sensor (not shown in the figure) is arranged on the inner wall of the air inlet end in the cyclone tube 10 or on the inner wall of the desulfurization tower in the air inlet direction of the cyclone tube 10. The signal output end of the air quality monitoring sensor is connected to the controller.

[0060] Specifically, in the cyclone tube 10 of the desulfurization tower, the air quality monitoring sensor is used to monitor the impurity content and air quality in the air flow entering the desulfurization tower in real time, and its signal output end is connected to the controller; when the air flow containing dust and other pollutants enters the desulfurization tower, the air quality monitoring sensor will immediately capture the gas change and convert the monitored data into an electrical signal, and transmit it to the controller in real time; after receiving this signal, the controller will dynamically adjust the working states of components such as the adsorption and dust removal mechanism 40, the control valve 46, and the jet head 53 according to the preset algorithms and logics; for example, when it is monitored that the dust concentration in the air flow increases, the controller may instruct to increase the gas supply volume of the gas storage container 45 to the slightly wet electric ball 44, and at the same time adjust the opening degree of the control valve 46 to improve the electrostatic adsorption performance of the electric ball; on the contrary, when the air quality is good, the controller may reduce the gas supply volume to save energy; therefore, through the combination of real-time monitoring and dynamic regulation in this example, not only the high-efficiency dust removal effect of the desulfurization tower is ensured, but also the reasonable utilization of energy is realized, and the operation efficiency and environmental protection performance of the entire desulfurization tower are improved.

[0061] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
