Description

Technical Field

[0001] This utility model relates to the field of purification, and in particular to an emergency device for a desulfurization slurry supply system. Background Technology

[0002] In existing flue gas desulfurization systems, since no backup limestone slurry tank is provided, when the mixing device of the limestone slurry tank needs maintenance, or when the slurry tank cannot store slurry normally for other reasons, an emergency measure is usually adopted: limestone powder is poured into a collection pit, stirred to make limestone slurry, and then supplied to the absorption tower. However, this emergency method has many drawbacks: on the one hand, a certain amount of bagged limestone powder needs to be stored normally. When supplying slurry in an emergency, it needs to be transported to the side of the collection pit, and then manually poured in and stirred to make slurry, which not only consumes a lot of manpower and increases the workload, but also increases costs; on the other hand, limestone powder stored for a long time is prone to moisture and clumping due to lack of use, further increasing the difficulty of slurry preparation. Utility Model Content

[0003] Therefore, it is necessary to provide an emergency device for the desulfurization slurry supply system to address the problem of the lack of a backup limestone slurry tank in the flue gas desulfurization system.

[0004] An emergency device for a desulfurization slurry supply system includes: a raw slurry storage tank assembly with a raw slurry storage chamber; an absorption tower assembly with a first input end that can be connected to or disconnected from the raw slurry storage tank assembly; an emergency storage tank assembly with an emergency storage chamber that can be connected to or disconnected from the absorption tower assembly with a second input end; and an emergency pipeline assembly, one end of which is disposed on the raw slurry storage tank assembly and / or the absorption tower assembly, and the other end of which is disposed on the emergency storage tank assembly, wherein the emergency storage chamber can be connected to or disconnected from the raw slurry storage chamber through the emergency pipeline assembly.

[0005] The above-disclosed emergency device for a desulfurization slurry supply system offers significant comprehensive advantages compared to the traditional emergency slurry supply mode of manually stirring limestone powder in the absorption tower's sump. The raw slurry storage tank assembly pre-stores finished limestone slurry in its storage chamber, replacing the traditional method of storing bagged limestone powder. In emergencies, this eliminates the need for cumbersome manual handling and stirring, significantly reducing labor costs and intensity, and greatly shortening emergency response time, enabling the system to quickly handle unexpected situations. The emergency storage tank assembly and emergency pipeline assembly work together to form a closed-loop slurry storage and transmission system. This system effectively avoids the drawbacks of limestone powder clumping due to moisture in the traditional method, ensuring uniform and stable slurry concentration and significantly improving the reliability of desulfurization efficiency. Notably, the emergency storage tank assembly is existing equipment, eliminating the need for additional storage tanks. By adding an emergency pipeline assembly between the raw slurry storage tank assembly and the emergency storage tank assembly, the emergency slurry storage function can be achieved, expanding the value of existing equipment and significantly reducing equipment investment costs. This design achieves higher economic benefits and safety performance at a lower modification cost, demonstrating significant technological advantages. Simultaneously, the closed-loop liquid storage reduces material loss, eliminating the need for additional sump mixing devices and powder storage space, thus lowering equipment investment and maintenance costs. The multi-directional connectivity design of the emergency pipeline assembly provides the system with flexible adaptability to various operating conditions. It can quickly switch to emergency slurry supply in case of raw slurry storage tank assembly failure or insufficient slurry. Emergency slurry stored in the emergency storage chamber is input into the absorber assembly from the second output end of the emergency storage tank assembly, ensuring continuous operation of the absorber assembly for desulfurization.

[0006] In one embodiment, the raw pulp storage tank assembly, the absorption tower assembly, the emergency storage tank assembly, and the emergency pipeline assembly work together to form at least a first working mode, a second working mode, a third working mode, and a fourth working mode. When the raw pulp storage tank assembly, the absorption tower assembly, the emergency storage tank assembly, and the emergency pipeline assembly are in the first working mode, the first input end of the raw pulp storage tank assembly is connected to the first input end of the absorption tower assembly, the emergency pipeline assembly is closed, the emergency storage chamber is blocked from the raw pulp storage chamber, and the second input end of the emergency storage tank assembly is blocked from the second input end of the absorption tower assembly. When the raw pulp storage tank assembly, the absorption tower assembly, the emergency storage tank assembly, and the emergency pipeline assembly are in the second working mode, the first input end of the raw pulp storage tank assembly is connected to the first input end of the absorption tower assembly, and the emergency storage tank assembly is connected to the second input end of the absorption tower assembly. When the second input end of the component is blocked, the emergency pipeline component is opened, and the emergency storage chamber is connected to the raw pulp storage chamber; when the raw pulp storage tank component, the absorption tower component, the emergency storage tank component, and the emergency pipeline component are in the third working mode, the first input end of the raw pulp storage tank component and the absorption tower component is connected or blocked, the emergency pipeline component is opened, the emergency storage chamber is connected to the raw pulp storage chamber, and the second input end of the emergency storage tank component and the absorption tower component is blocked; when the raw pulp storage tank component, the absorption tower component, the emergency storage tank component, and the emergency pipeline component are in the fourth working mode, the first input end of the raw pulp storage tank component and the absorption tower component is blocked, the emergency storage chamber is blocked from the raw pulp storage chamber, the emergency pipeline component is closed, and the second input end of the emergency storage tank component and the absorption tower component is connected. By utilizing the coordinated work of the raw pulp storage tank component, the absorption tower component, the emergency storage tank component, and the emergency pipeline component, the first working mode, the second working mode, the third working mode, and the fourth working mode are formed. In the first operating mode, the raw slurry storage tank assembly operates normally, directly supplying slurry to the first input end of the absorber tower assembly. The emergency pipeline assembly is closed, ensuring the system operates with the simplest process under normal conditions, reducing energy loss and redundant pipeline flow, and guaranteeing the stability and economy of desulfurization efficiency. Simultaneously, the emergency storage tank is kept in standby mode, providing safety redundancy for emergencies. The second operating mode requires preparation before maintenance of the raw slurry storage tank assembly. While maintaining desulfurization in the absorber tower assembly, the emergency pipeline assembly is opened, connecting the raw slurry storage chamber and the emergency storage chamber. Slurry is replenished to the emergency storage tank during system downtime, achieving a dynamic balance of "supplying slurry while preparing slurry." This allows for continuous storage of emergency slurry without affecting desulfurization operations.The third operating mode connects the two storage chambers by activating the emergency pipeline assembly. This disconnects the connection between the raw slurry storage tank assembly and the first input end of the absorber tower assembly, but allows for reconnection when needed by the absorber tower assembly. Simultaneously, the remaining slurry in the raw slurry storage tank assembly is evacuated and transferred to the emergency storage chamber of the emergency storage tank assembly, preparing for maintenance of the raw slurry storage tank assembly. In the fourth operating mode, the raw slurry storage tank assembly is completely deactivated, and the output end of the emergency storage tank assembly directly supplies slurry to the second input end of the absorber tower assembly, forming a direct emergency slurry supply link. At this time, the emergency control valve of the emergency pipeline assembly can be closed to clean the pipelines of the raw slurry storage tank assembly, the first input end of the absorber tower assembly, and the emergency pipeline assembly. Fault detection and repair of the raw slurry storage tank assembly are also possible. This mode seamlessly switches to emergency slurry supply, preventing desulfurization system shutdown due to slurry supply interruption. Redundancy design enhances resilience and provides multi-layered protection for the safe, stable, and economical operation of the desulfurization system, making it particularly suitable for scenarios with high requirements for continuous production and urgent emergency response needs.

[0007] In one embodiment, the emergency piping assembly includes a tee connector, an emergency piping body, a flushing input, a flushing output, and an emergency control valve. The first end of the tee connector is located on the raw slurry storage tank assembly, the second end of the tee connector is located on the absorption tower assembly, the emergency piping body is located on the third end of the tee connector, the flushing input is located on the section of the emergency piping body away from the tee connector, the flushing output is located on the section of the emergency piping body close to the tee connector, and the emergency control valve is located on the section of the emergency piping body between the flushing output and the tee connector. Through the organic combination of the components of the emergency piping assembly, the stable operation and emergency needs of the desulfurization slurry supply system are effectively guaranteed. The three ports of the tee interface connect to the raw slurry storage tank assembly, the absorption tower assembly, and the emergency pipeline body, respectively. Combined with the opening and closing of the emergency control valve, four operating modes can be flexibly switched to achieve functions such as normal slurry supply, slurry preparation, raw slurry transfer, and emergency slurry supply, avoiding the complex structure and high cost problems caused by traditional multi-pipeline designs. The flushing input and output components allow for the introduction of clean water to flush the emergency pipeline body, preventing slurry residue from solidifying and clogging the pipeline, and avoiding the deterioration of residual slurry affecting the quality of fresh slurry. The emergency control valve body is located on the pipeline body between the flushing output component and the tee interface, i.e., at the lowest point of the emergency pipeline body. The flushing input component, located at a higher point on the emergency pipeline body, facilitates complete flushing of the entire pipeline section during flushing. Furthermore, the emergency control valve body controls the on / off state of the emergency pipeline body. When emergency slurry needs to be stored, the valve body is opened to connect the emergency storage chamber and the raw slurry storage chamber. When the emergency slurry storage is complete and the pipelines of the raw slurry storage tank assembly, the absorption tower assembly, and the emergency pipeline body need to be cleaned, the valve body is closed. Emergency piping components integrate connectivity, control, and cleaning functions, reducing connection points and leakage risks. Standardized interfaces facilitate automated cleaning, and corrosion-resistant materials extend service life, comprehensively improving system reliability, ease of maintenance, and operational efficiency.

[0008] In one embodiment, the emergency pipeline body includes an emergency inlet pipeline, a first connector, an emergency transition pipeline, a second connector, and an emergency input pipeline. One end of the emergency inlet pipeline is located at the third end of the tee connector. The first connector is located at the other end of the emergency inlet pipeline. One end of the emergency transition pipeline is located at the first connector. The second connector is located at the other end of the emergency transition pipeline. The emergency input pipeline is located at the second connector and passes through the emergency storage tank assembly. By orderly connecting the emergency inlet pipeline, the first connector, the emergency transition pipeline, the second connector, and the emergency input pipeline, an efficient and stable transmission channel is constructed for the emergency operation of the desulfurization slurry supply system. One end of the emergency inlet pipe is connected to a tee connector to ensure rapid connection to the slurry storage tank assembly and the absorption tower assembly. During emergency slurry transfer, it promptly receives and delivers slurry to the emergency storage chamber. The first connector allows the emergency transition pipe to be tilted, using gravity to ensure complete flow of emergency slurry into the emergency storage chamber. Its detachable connection design facilitates installation, disassembly, and maintenance. In case of blockages or damage, damaged sections can be quickly located and replaced, shortening maintenance time. It also allows for flexible combination of different pipe specifications during system upgrades or adjustments, improving system adaptability. As an intermediate transmission section, the emergency transition pipe's length can be adjusted according to the site layout to ensure smooth slurry entry into the emergency storage tank assembly while avoiding spatial interference with other equipment, ensuring a rational pipeline layout. The emergency input pipe at the second connector passes through the emergency storage tank assembly, enabling precise slurry injection. In the second and third operating modes, it efficiently stores slurry from the slurry storage tank assembly into the emergency storage tank assembly, ensuring unimpeded emergency slurry supply.

[0009] In one embodiment, the horizontal plane of the end of the emergency inlet pipe connected to the first connector is higher than the horizontal plane of the emergency storage tank assembly. By setting the horizontal plane of the end of the emergency inlet pipe connected to the first connector to be higher than the horizontal plane of the emergency storage tank assembly, gravity can be fully utilized to achieve gravity-driven drainage of limestone slurry, effectively avoiding the problem of material accumulation in the pipeline. When emergency slurry needs to be stored, the limestone slurry in the emergency transition pipe can flow completely into the emergency storage tank assembly under gravity. Compared with horizontal or low-level arrangements, this high-level design avoids slurry stagnation in the pipeline due to insufficient flow momentum, prevents slurry solidification and blockage of the pipeline, and reduces the frequency of manual dredging and maintenance costs; at the same time, the absence of residual slurry in the pipeline also reduces the risk of subsequent slurry supply quality being affected by slurry deterioration, improves the response efficiency and stability when the system restarts, and ensures continuous and reliable operation of the desulfurization process.

[0010] In one embodiment, the horizontal plane height of the end of the emergency transition pipe connected to the first connector is greater than the horizontal plane height of the end of the emergency transition pipe connected to the second connector. By utilizing the fact that the horizontal plane height of the end of the emergency transition pipe connected to the first connector is greater than the horizontal plane height of the end of the emergency transition pipe connected to the second connector, i.e., the emergency transition pipe is set at an angle, such as 60°, between the emergency transition pipe and the emergency inlet pipe. When it is necessary to store emergency slurry, the slurry in the pipe can flow rapidly from high to low along the inclined direction into the emergency storage tank assembly, avoiding slurry stagnation, deposition, and solidification caused by the horizontal arrangement of the pipe. At the same time, this inclined design can ensure that the slurry in the emergency transition pipe is completely emptied, reducing the burden of manual cleaning, reducing the risk of pipe blockage, maintaining the long-term unobstructed flow of the emergency pipe, and ensuring the reliability and stability of the system when switching between different working modes.

[0011] In one embodiment, the emergency storage tank assembly includes an emergency storage tank, a second agitator, a vent pipe, and an emergency slurry outlet pipe. The emergency storage tank has an emergency storage chamber. The second agitator is mounted on the emergency storage tank and located within the emergency storage chamber. The vent pipe is mounted on the emergency storage tank, and the emergency input pipe passes through the vent pipe. The emergency slurry outlet pipe is mounted on the emergency storage tank and can communicate with the second input end of the absorption tower assembly. By utilizing the emergency storage tank assembly and the close cooperation of its components, a reliable guarantee is provided for the continuous and stable operation of the desulfurization slurry supply system during the maintenance of the raw slurry storage tank assembly. As the core carrier, the emergency storage tank's internal emergency storage chamber is used to store sufficient limestone slurry, providing a material basis for emergency slurry supply. The continuous operation of the second agitator effectively prevents the limestone particles in the slurry from settling and clumping, ensuring a uniform and stable slurry concentration and avoiding the impact of slurry quality problems on desulfurization efficiency. The vent pipe maintains pressure balance inside and outside the emergency storage tank, ensuring smooth slurry inflow and outflow and preventing slurry supply interruptions due to abnormal pressure. The emergency input pipe is cleverly integrated into the vent pipe, achieving efficient slurry transport while minimizing tank openings and reducing leakage risk. Furthermore, the connection between the emergency slurry outlet pipe and the second input end of the absorber tower assembly allows for the rapid establishment of an independent emergency slurry supply channel during raw slurry storage tank assembly maintenance. This ensures timely and stable delivery of slurry from the emergency storage chamber to the absorber tower assembly, guaranteeing uninterrupted desulfurization operations and preventing system shutdowns due to slurry supply interruptions. This significantly enhances the system's resilience and continuous operational reliability.

[0012] In one embodiment, the vent pipe includes a vent pipe body and a connecting flange. The connecting flange is disposed on the emergency storage tank, and the vent pipe body is disposed on the connecting flange. The horizontal plane height of the end of the emergency input pipeline away from the second connector is less than the horizontal plane height of the connecting flange. By utilizing the combined structure of the vent pipe body and the connecting flange, and setting the height of the output end of the emergency input pipeline lower than the connecting flange, it plays an important role in ensuring the stable operation of the desulfurization slurry supply system. The connecting flange is securely installed on the emergency storage tank, providing a reliable connection base for the vent pipe body and maintaining stable system pressure. The vent pipe body enables gas exchange between the emergency storage tank and the outside environment, balancing the internal and external air pressures of the tank, preventing negative pressure from obstructing slurry intake due to slurry inflow or outflow, or preventing safety hazards caused by excessive pressure. The height of the emergency input pipeline is lower than that of the connecting flange. If the output end of the emergency input pipeline extends 150mm below the connecting flange, the height difference will allow the slurry to flow smoothly into the emergency storage tank by gravity during the slurry transportation process. This will prevent the slurry from leaking from the connecting flange due to unreasonable pipeline layout and ensure that the emergency slurry can smoothly enter the emergency storage chamber of the emergency storage tank.

[0013] In one embodiment, the raw slurry storage tank assembly includes a raw slurry storage tank, a first agitator, a raw slurry output pipeline, a return pipeline, and an output control component. The raw slurry storage tank has a raw slurry storage chamber. The first agitator is mounted on the raw slurry storage tank and located within the raw slurry storage chamber. One end of the raw slurry output pipeline is mounted on the raw slurry storage tank, and the other end is mounted on the emergency pipeline assembly. One end of the return pipeline is mounted on the raw slurry output pipeline, and the other end is mounted on the raw slurry storage tank. The output control component is mounted on the raw slurry output pipeline and / or the return pipeline. By utilizing the raw slurry storage tank assembly and the coordinated operation of its components, integrated and efficient management of slurry storage, mixing, transportation, and circulation is achieved. As the core container, the raw slurry storage tank provides ample storage space for limestone slurry within its internal raw slurry storage chamber, ensuring the daily slurry supply needs of the desulfurization system. The first agitator continuously operates, stirring the slurry within the tank to prevent limestone particles from settling and stratifying, effectively improving the uniformity and activity of the slurry, and ensuring the efficient conduct of the desulfurization reaction. One end of the raw slurry output pipeline connects to the raw slurry storage tank, and the other end connects to the emergency pipeline assembly, forming the main channel for slurry output. By adjusting the output control unit, the slurry flow and pressure can be precisely controlled, enabling switching between supplying slurry to the absorption tower assembly and preparing slurry for the emergency storage tank assembly. The return pipeline connects to the raw slurry output pipeline at one end and returns to the raw slurry storage tank at the other, forming an internal circulation loop for the slurry. Adjusting the return ratio with the output control unit allows some of the exported slurry to flow back into the tank, continuously driving the slurry flow within the tank. This not only prevents the slurry from clumping due to long-term stagnation but also assists the first agitator in further mixing the slurry, enhancing the mixing effect.

[0014] In one embodiment, the absorption tower assembly includes an absorption tower body, a main input pipeline, an auxiliary input pipeline, an input control component, and other pipelines. One end of the main input pipeline is disposed on the emergency pipeline assembly, and the other end of the main input pipeline is disposed on the absorption tower body. The auxiliary input pipeline is disposed on the main input pipeline, with one end of the auxiliary pipeline disposed on the absorption tower body and the other end disposed on the emergency storage tank assembly. The input control component is disposed on the main input pipeline, the auxiliary input pipeline, and the other pipelines. The absorption tower body has a flue gas inlet and a flue gas outlet. By configuring the absorption tower body, which serves as the core reaction vessel, its flue gas inlet and outlet form a flue gas treatment channel, providing space for the reaction of sulfur-containing flue gas with desulfurization slurry. The main input pipeline connects to the emergency pipeline assembly at one end and to the absorber tower body at the other, serving as the main channel for slurry input. Under normal operating conditions, slurry from the raw slurry storage tank assembly can be transported to the absorber tower body for desulfurization. In the event of a malfunction in the input control components of the main input pipeline, the auxiliary input pipeline can be used for continuous slurry supply, ensuring uninterrupted desulfurization. The pipeline connects the absorber tower body and the emergency storage tank assembly, enabling bidirectional slurry flow. Input control components are distributed along each pipeline; precise adjustment of the pipeline's opening and closing ensures that the absorber tower can stably, efficiently, and continuously complete the flue gas desulfurization task under various operating conditions.

[0015] In one embodiment, a water collection pit is also included, which is connected to the output end of the absorption tower assembly. By connecting the water collection pit to the output end of the absorption tower assembly, residual slurry, flushing water, and other solid waste liquids discharged during the operation of the absorption tower assembly can be collected, providing a buffer space for the system and avoiding excessive instantaneous load on subsequent treatment equipment due to direct discharge.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0034] The following describes, with reference to the accompanying drawings, some embodiments of the desulfurization slurry supply system emergency device of this utility model.

[0035] Example 1

[0036] like Figures 1 to 10 As shown, this embodiment discloses an emergency device for a desulfurization slurry supply system, including: a raw slurry storage tank assembly 1, which has a raw slurry storage chamber 101; an absorption tower assembly 2, the first input end of which can be connected to or disconnected from the raw slurry storage tank assembly 1; an emergency storage tank assembly 3, which has an emergency storage chamber 301 and can be connected to or disconnected from the second input end of the absorption tower assembly 2; and an emergency pipeline assembly 4, one end of which is disposed on the raw slurry storage tank assembly 1 and / or the absorption tower assembly 2, and the other end of which is disposed on the emergency storage tank assembly 3, wherein the emergency storage chamber 301 can be connected to or disconnected from the raw slurry storage chamber 101 through the emergency pipeline assembly 4.

[0037] This application discloses an emergency device for a desulfurization slurry supply system. Compared with the traditional emergency slurry supply mode of manually stirring limestone powder in the absorption tower sump, this emergency device for a desulfurization slurry supply system has significant comprehensive advantages. The raw slurry storage tank assembly 1's raw slurry storage chamber 101 pre-stores finished limestone slurry, replacing the storage method of bagged limestone powder. In emergencies, there is no need for cumbersome operations such as manual handling and stirring, significantly reducing labor costs and labor intensity, greatly shortening emergency response time, and enabling the system to quickly respond to sudden operating conditions. The emergency storage tank assembly 3 and the emergency pipeline assembly 4 work together to construct a closed slurry storage and transmission system. This system effectively avoids the drawbacks of limestone powder clumping due to moisture in the traditional mode, ensuring uniform and stable slurry concentration and significantly improving the reliability of desulfurization efficiency. It is worth mentioning that the emergency storage tank assembly 3 is existing equipment, eliminating the need for additional storage tanks. By adding the emergency pipeline assembly 4 between the raw slurry storage tank assembly 1 and the emergency storage tank assembly 3, the emergency slurry storage function can be achieved, both expanding the use value of existing equipment and significantly reducing equipment investment costs. This design achieves higher economic benefits and safety performance with lower modification costs, demonstrating significant technological advantages. Simultaneously, the closed-loop liquid storage reduces material loss, eliminating the need for additional sump mixing devices and powder storage space, thus lowering equipment investment and maintenance costs. The multi-directional connectivity design of the emergency pipeline assembly 4 provides the system with flexible adaptability to various operating conditions. It can quickly switch to emergency slurry supply in case of failure of the raw slurry storage tank assembly 1 or insufficient slurry. Emergency slurry stored in the emergency storage chamber 301 is input from the second output end of the emergency storage tank assembly 3 into the absorber assembly 2, ensuring continuous operation of the absorber assembly 2 for desulfurization.

[0038] like Figure 1As shown, in addition to the features of the above embodiments, this embodiment further defines that: the raw pulp storage tank assembly 1, the absorption tower assembly 2, the emergency storage tank assembly 3, and the emergency pipeline assembly 4 work together and form at least a first working mode, a second working mode, a third working mode, and a fourth working mode; when the raw pulp storage tank assembly 1, the absorption tower assembly 2, the emergency storage tank assembly 3, and the emergency pipeline assembly 4 are in the first working mode, the first input end of the raw pulp storage tank assembly 1 is connected to the first input end of the absorption tower assembly 2, the emergency pipeline assembly 4 is closed, the emergency storage chamber 301 is blocked from the raw pulp storage chamber 101, and the second input end of the emergency storage tank assembly 3 is blocked from the second input end of the absorption tower assembly 2; when the raw pulp storage tank assembly 1, the absorption tower assembly 2, the emergency storage tank assembly 3, and the emergency pipeline assembly 4 are in the second working mode, the first input end of the raw pulp storage tank assembly 1 is connected to the first input end of the absorption tower assembly 2, and the emergency storage tank assembly 301 is closed. When the second input end of the absorber assembly 2 is blocked, the emergency pipeline assembly 4 is opened, and the emergency storage chamber 301 is connected to the raw pulp storage chamber 101. When the raw pulp storage tank assembly 1, absorber assembly 2, emergency storage tank assembly 3, and emergency pipeline assembly 4 are in the third working mode, the first input end of the raw pulp storage tank assembly 1 is connected to or blocked from the absorber assembly 2, the emergency pipeline assembly 4 is opened, the emergency storage chamber 301 is connected to the raw pulp storage chamber 101, and the second input end of the emergency storage tank assembly 3 is blocked from the absorber assembly 2. When the raw pulp storage tank assembly 1, absorber assembly 2, emergency storage tank assembly 3, and emergency pipeline assembly 4 are in the fourth working mode, the first input end of the raw pulp storage tank assembly 1 is blocked from the absorber assembly 2, the emergency storage chamber 301 is blocked from the raw pulp storage chamber 101, the emergency pipeline assembly 4 is closed, and the second input end of the emergency storage tank assembly 3 is connected to the absorber assembly 2. By utilizing the coordinated work of the raw pulp storage tank assembly 1, absorber assembly 2, emergency storage tank assembly 3, and emergency pipeline assembly 4, the first working mode, second working mode, third working mode, and fourth working mode are formed. In the first operating mode, the raw slurry storage tank assembly 1 can operate normally, directly supplying slurry to the first input end of the absorber tower assembly 2. The emergency pipeline assembly 4 is closed, ensuring that the system operates with the simplest process under normal conditions, reducing energy loss and redundant pipeline flow, ensuring the stability and economy of desulfurization efficiency, and keeping the emergency storage tank in standby status to reserve safety redundancy for emergencies. The second operating mode is the preparation mode for the raw slurry storage tank assembly 1 before maintenance. While maintaining the desulfurization of the absorber tower assembly 2, the emergency pipeline assembly 4 is opened to connect the raw slurry storage chamber 101 and the emergency storage chamber 301. Slurry is replenished to the emergency storage tank during system operation intervals to achieve a dynamic balance of "supplying slurry while preparing slurry". Emergency slurry can be continuously stored without affecting the desulfurization operation.In the third operating mode, the emergency pipeline assembly 4 connects the two storage chambers. This disconnects the connection between the raw slurry storage tank assembly 1 and the first input end of the absorption tower assembly 2. However, the connection can be restored when needed by the absorption tower assembly 2. Simultaneously, the remaining slurry in the raw slurry storage tank assembly 1 is evacuated and transferred to the emergency storage chamber 301 of the emergency storage tank assembly 3, preparing for maintenance of the raw slurry storage tank assembly 1. In the fourth operating mode, the raw slurry storage tank assembly 1 is completely shut down. The output end of the emergency storage tank assembly 3 directly supplies slurry to the second input end of the absorption tower assembly 2, forming a direct emergency slurry supply link. At this time, the emergency control valve 45 of the emergency pipeline assembly 4 can be closed to clean the pipelines of the raw slurry storage tank assembly 1, the first input end of the absorption tower assembly 2, and the emergency pipeline assembly 4. Fault detection and repair of the raw slurry storage tank assembly 1 can also be performed. This mode allows for seamless switching to emergency slurry supply, preventing desulfurization system shutdown due to slurry supply interruption. The redundancy design enhances the ability to withstand risks and provides multi-level protection for the safe, stable and economical operation of the desulfurization system, which is especially suitable for scenarios with high requirements for continuous production and urgent emergency response needs.

[0039] like Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines: the emergency pipeline assembly 4 includes a tee interface 41, an emergency pipeline body 42, a flushing input 43, a flushing output 44, and an emergency control valve body 45. The first end of the tee interface 41 is disposed on the raw slurry storage tank assembly 1, the second end of the tee interface 41 is disposed on the absorption tower assembly 2, the emergency pipeline body 42 is disposed on the third end of the tee interface 41, the flushing input 43 is disposed on the pipeline of the emergency pipeline body 42 away from the tee interface 41, the flushing output 44 is disposed on the pipeline of the emergency pipeline body 42 close to the tee interface 41, and the emergency control valve body 45 is disposed on the pipeline of the emergency pipeline body 42 located between the flushing output 43 and the tee interface 41. Through the organic combination of the components of the emergency pipeline assembly 4, the stable operation and emergency needs of the desulfurization slurry supply system are effectively guaranteed. The three ports of the tee connector 41 are respectively connected to the raw slurry storage tank assembly 1, the absorption tower assembly 2, and the emergency pipeline body 42. With the opening and closing of the emergency control valve 45, four working modes can be flexibly switched to realize functions such as normal slurry supply, slurry preparation, raw slurry transfer, and emergency slurry supply, avoiding the complex structure and high cost problems caused by traditional multi-pipeline designs. The flushing input 43 and flushing output 44 allow the introduction of clean water to flush the emergency pipeline body 42, preventing slurry residue from solidifying and clogging the pipeline, and avoiding the deterioration of residual slurry affecting the quality of fresh slurry. The emergency control valve 45 is located on the pipeline of the emergency pipeline body 42 between the flushing output 43 and the tee connector 41, that is, at the lowest point of the emergency pipeline body 42. The flushing input 43, located at a higher point on the emergency pipeline body 42, facilitates complete flushing of the entire pipeline section when flushing the emergency pipeline body 42. Furthermore, the emergency control valve 45 can control the on / off state of the emergency pipeline body 42. When emergency slurry needs to be stored, the valve opens to connect the emergency storage chamber 301 and the raw slurry storage chamber 101. When the emergency slurry storage is complete and the pipelines of the raw slurry storage tank assembly 1 and the absorption tower assembly 2, as well as the emergency pipeline body 42, need to be cleaned, the valve closes. The emergency pipeline assembly 4 integrates the functions of connection, control, and cleaning, reducing connection points and leakage risks. Standardized interfaces facilitate automated cleaning, and corrosion-resistant materials extend service life, comprehensively improving the system's reliability, ease of maintenance, and operational efficiency.

[0040] like Figure 9 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further defines: the emergency pipeline body 42 includes an emergency inlet pipeline 421, a first connector 422, an emergency transition pipeline 423, a second connector 424, and an emergency input pipeline 425. One end of the emergency inlet pipeline 421 is located on the third end of the tee interface 41, the first connector 422 is located on the other end of the emergency inlet pipeline 421, one end of the emergency transition pipeline 423 is located on the first connector 422, the second connector 424 is located on the other end of the emergency transition pipeline 423, and the emergency input pipeline 425 is located on the second connector 424. The emergency input pipeline 425 passes through the emergency storage tank assembly 3. By orderly connecting the emergency inlet pipeline 421, the first connector 422, the emergency transition pipeline 423, the second connector 424, and the emergency input pipeline 425, an efficient and stable transmission channel is constructed for the emergency operation of the desulfurization slurry supply system. One end of the emergency inlet pipe 421 is connected to the tee interface 41 to ensure rapid connection to the communication system between the raw slurry storage tank assembly 1 and the absorption tower assembly 2. During emergency slurry transfer, it promptly receives and transports the slurry to the emergency storage chamber 301. The first connector 422 allows the emergency transition pipe 423 to be tilted, using gravity to ensure complete flow of the emergency slurry into the emergency storage chamber 301. The detachable connection design facilitates the installation, disassembly, and maintenance of the emergency transition pipe 423. In case of blockages or damage, the damaged parts can be quickly located and replaced, shortening maintenance time. When upgrading or adjusting the system, different specifications of pipelines can be flexibly combined to improve system adaptability; the emergency transition pipeline 423, as an intermediate transmission section, can be adjusted in length according to the site space layout to ensure that the slurry can smoothly enter the emergency storage tank assembly 3, while avoiding spatial interference with other equipment and ensuring the rationality of the pipeline layout; the emergency input pipeline 425, which is set in the second joint 424, passes through the emergency storage tank assembly 3 to achieve precise injection of slurry. In the second and third working modes, the slurry of the original slurry storage tank assembly 1 is efficiently stored in the emergency storage tank assembly 3 to ensure that the emergency slurry supply process is unobstructed.

[0041] like Figure 9 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that the horizontal plane height of the end where the emergency inlet pipe 421 connects to the first connector 422 is greater than the horizontal plane height of the emergency storage tank assembly 3. By setting the horizontal plane height of the end where the emergency inlet pipe 421 connects to the first connector 422 to be greater than the horizontal plane height of the emergency storage tank assembly 3, gravity can be fully utilized to achieve gravity-driven drainage of limestone slurry, effectively avoiding the problem of material accumulation in the pipe. When emergency slurry needs to be stored, the limestone slurry in the emergency transition pipe 423 can flow completely into the emergency storage tank assembly 3 under gravity. Compared with horizontal or low-level arrangements, this high-level design avoids slurry stagnation in the pipe due to insufficient flow power, prevents slurry solidification and blockage of the pipe, and reduces the frequency of manual dredging and maintenance costs; at the same time, the absence of residual slurry in the pipe also reduces the risk of subsequent slurry supply quality being affected by slurry deterioration, improves the response efficiency and stability when the system restarts, and ensures continuous and reliable operation of the desulfurization process.

[0042] like Figure 9 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the horizontal plane height of the end of the emergency transition pipe 423 connected to the first connector 422 is greater than the horizontal plane height of the end of the emergency transition pipe 423 connected to the second connector 424. By utilizing the fact that the horizontal plane height of the end of the emergency transition pipe 423 connected to the first connector 422 is greater than the horizontal plane height of the end of the emergency transition pipe 423 connected to the second connector 424, that is, by setting the emergency transition pipe 423 at an angle, such as 60°, a certain angle is formed between the emergency transition pipe 423 and the emergency inlet pipe 421. When it is necessary to store emergency slurry, the slurry in the pipe can flow quickly from high to low along the inclined direction into the emergency storage tank assembly 3, avoiding slurry stagnation, deposition and solidification due to the horizontal arrangement of the pipe, thus avoiding the formation of accumulated material. At the same time, this inclined design can ensure that the slurry in the emergency transition pipe 423 is completely emptied, reducing the burden of manual cleaning, reducing the risk of pipe blockage, maintaining the long-term unobstructed flow of the emergency pipe, and ensuring the reliability and stability of the system when switching between different working modes.

[0043] like Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the emergency storage tank assembly 3 includes an emergency storage tank 31, a second stirrer 32, a vent pipe 33, and an emergency slurry discharge pipe 34. The emergency storage tank 31 is provided with an emergency storage chamber 301. The second stirrer 32 is disposed on the emergency storage tank 31 and located in the emergency storage chamber 301. The vent pipe 33 is disposed on the emergency storage tank 31. An emergency input pipe 425 passes through the vent pipe 33. The emergency slurry discharge pipe 34 is disposed on the emergency storage tank 31 and can be connected to the second input end of the absorption tower assembly 2. By utilizing the emergency storage tank assembly 3 and the close cooperation of its components, a reliable guarantee is provided for the continuous and stable operation of the desulfurization slurry supply system during the maintenance of the raw slurry storage tank assembly 1. The emergency storage tank 31 serves as the core carrier, with its internal emergency storage chamber 301 storing sufficient limestone slurry to provide the material basis for emergency slurry supply. The second agitator 32 operates continuously, effectively preventing limestone particles in the slurry from settling and clumping, ensuring a uniform and stable slurry concentration, and avoiding impacts on desulfurization efficiency due to slurry quality issues. The vent pipe 33 maintains the pressure balance inside and outside the emergency storage tank 31, ensuring smooth slurry inflow and outflow and preventing slurry supply interruptions due to abnormal pressure. The emergency input pipe 425 is cleverly integrated into the vent pipe, achieving efficient slurry transport while reducing tank openings and mitigating leakage risks. The connection between the emergency slurry outlet pipe 34 and the second input end of the absorption tower assembly 2 allows for the rapid establishment of an independent emergency slurry supply channel during maintenance of the raw slurry storage tank assembly 1. This ensures timely and stable delivery of the slurry from the emergency storage chamber 301 to the absorption tower assembly 2, guaranteeing uninterrupted desulfurization operations and preventing system shutdowns due to slurry supply interruptions. This significantly enhances the system's resilience and continuous operational reliability.

[0044] like Figure 6 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the vent pipe 33 includes a vent pipe body 331 and a connecting flange 332. The connecting flange 332 is disposed on the emergency storage tank 31, and the vent pipe body 331 is disposed on the connecting flange 332. The horizontal plane height of the end of the emergency input pipe 425 away from the second connector 424 is less than the horizontal plane height of the connecting flange 332. By utilizing the combined structure of the vent pipe body 331 and the connecting flange 332 in the vent pipe 33, and setting the height of the output end of the emergency input pipe 425 lower than that of the connecting flange 332, it plays an important role in ensuring the stable operation of the desulfurization slurry supply system. The connecting flange 332 is securely installed on the emergency storage tank 31, providing a reliable connection base for the vent pipe body 331 and maintaining stable system pressure; the vent pipe body 331 realizes the gas exchange between the emergency storage tank 31 and the outside world, balances the gas pressure inside and outside the tank, and prevents negative pressure from obstructing slurry intake due to slurry inflow or outflow, or prevents safety hazards caused by excessive pressure. The height of the emergency input pipe 425 is lower than that of the connecting flange. If the output end of the emergency input pipe 425 is extended 150mm below the connecting flange 332, the height difference will be used to allow the slurry to flow smoothly into the emergency storage tank by gravity during the slurry transportation process. This will prevent the slurry from leaking from the connecting flange 332 due to unreasonable pipe layout, and ensure that the emergency slurry can smoothly enter the emergency storage chamber 301 of the emergency storage tank 31.

[0045] like Figures 1 to 3As shown, in addition to the features of the above embodiments, this embodiment further defines: a pulp storage tank assembly 1 comprising a pulp storage tank 11, a first agitator 12, a pulp output pipeline 13, a return pipeline 14, and an output control component 15. The pulp storage tank 11 has a pulp storage chamber 101. The first agitator 12 is disposed on the pulp storage tank 11 and located in the pulp storage chamber 101. One end of the pulp output pipeline 13 is disposed on the pulp storage tank 11, and the other end is disposed on the emergency pipeline assembly 4. One end of the return pipeline 14 is disposed on the pulp output pipeline 13, and the other end is disposed on the pulp storage tank 11. The output control component 15 is disposed on the pulp output pipeline 13 and / or the return pipeline 14. By utilizing the pulp storage tank assembly 1 through the coordinated operation of its components, integrated and efficient management of pulp storage, mixing, transportation, and circulation is achieved. The raw slurry storage tank 11 serves as the core container, with its internal raw slurry storage chamber 101 providing ample storage space for the limestone slurry, ensuring the daily slurry supply needs of the desulfurization system. The first agitator 12 operates continuously, stirring the slurry within the tank to prevent limestone particles from settling and stratifying, effectively improving the uniformity and activity of the slurry, and ensuring the efficient conduct of the desulfurization reaction. One end of the raw slurry output pipeline 13 is connected to the raw slurry storage tank 11, and the other end is connected to the emergency pipeline assembly 4, forming the main channel for slurry output. Through the adjustment of the output control component 15, the slurry flow rate and pressure can be precisely controlled, realizing the function of switching between supplying slurry to the absorption tower assembly 2 and preparing slurry for the emergency storage tank assembly 3. One end of the return pipe 14 is connected to the raw slurry output pipe 13, and the other end returns to the raw slurry storage tank 11, forming an internal circulation loop for the slurry. With the output control component 15, the return ratio can be adjusted so that some of the exported slurry can flow back into the tank, continuously driving the slurry flow in the tank. This not only prevents the slurry from clumping due to long-term standing, but also assists the first agitator in further mixing the slurry and enhancing the mixing effect.

[0046] like Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines: the absorption tower assembly 2 includes an absorption tower body 21, a main input pipeline 22, an auxiliary input pipeline 23, an input control component 24, and a pipeline 25. One end of the main input pipeline 22 is installed on the emergency pipeline assembly 4, and the other end of the main input pipeline 22 is installed on the absorption tower body 21. The auxiliary input pipeline 23 is installed on the main input pipeline 22. One end of the pipeline 25 is installed on the absorption tower body 21, and the other end of the pipeline 25 is installed on the emergency storage tank assembly 3. The input control component 24 is installed on the main input pipeline 22, the auxiliary input pipeline 23, and the pipeline 25. The absorption tower body 21 is provided with a flue gas inlet 201 and a flue gas outlet 202. By setting the absorption tower body 21, the absorption tower body 21 serves as the core reaction vessel, and its flue gas inlet 201 and flue gas outlet 202 form a flue gas treatment channel, providing space for the reaction of sulfur-containing flue gas and desulfurization slurry. The main input pipeline 22 connects to the emergency pipeline assembly 4 at one end and to the absorption tower body 21 at the other end. It serves as the main channel for slurry input. Under normal operating conditions, slurry from the raw slurry storage tank assembly 1 can be transported to the absorption tower body 21 for desulfurization. If the input control component 24 in the main input pipeline 22 malfunctions, the auxiliary input pipeline 23 can be used for continuous slurry transport, ensuring uninterrupted desulfurization. Pipeline 25 connects the absorption tower body 21 and the emergency storage tank assembly 3, enabling bidirectional slurry flow. Input control components are distributed on each pipeline. By precisely adjusting the opening and closing of the pipelines, the absorption tower can stably, efficiently, and continuously complete the flue gas desulfurization task under various operating conditions.

[0047] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further includes a water collection pit 5, which is connected to the output end of the absorption tower assembly 2. By connecting the water collection pit 5 to the output end of the absorption tower assembly 2, the residual slurry, flushing water, and other solid waste liquid discharged by the absorption tower assembly 2 during operation can be collected, providing a buffer space for the system and avoiding excessive instantaneous load on subsequent treatment equipment due to direct discharge.
