Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology, and more specifically, to a desulfurization device. Background Technology

[0002] Desulfurization units, as key equipment in industrial flue gas treatment systems, are widely used in thermal power generation, metallurgy, chemical industry, and other fields to remove sulfur oxides from flue gas and achieve environmentally friendly emissions. In actual operation, desulfurization processes often involve the input of high-temperature flue gas and complex chemical reactions, resulting in high internal temperatures. Although some equipment is equipped with insulation layers to maintain the reaction temperature, the sensors, actuators, electrical control modules, and some mechanical components installed inside are still exposed to high-temperature radiation and heat conduction environments for extended periods.

[0003] Because existing desulfurization devices generally lack effective heat dissipation designs or cooling structures, heat accumulates inside the equipment and is difficult to dissipate in a timely manner. This causes the operating temperature of key components to exceed their rated range, affecting their performance stability and response accuracy. For example, high temperatures can easily lead to accelerated aging of electronic components, deterioration of insulation material performance, thermal deformation or lubrication failure of mechanical parts, which in turn can cause equipment malfunctions, control failures, or sudden malfunctions, seriously reducing the reliability and safety of system operation. Utility Model Content

[0004] This invention provides a desulfurization device that can improve the thermal management conditions of internal components, reduce operating temperature rise, enhance equipment reliability and maintainability, and ensure the long-term stable operation of the desulfurization system.

[0005] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides a desulfurization device, comprising: A desulfurization tower is provided with a reaction chamber, an inlet pipe, and an outlet pipe, both of which are connected to the reaction chamber. A spraying mechanism is installed in the desulfurization tower and is used to spray water into the reaction chamber. A sensor is installed in the desulfurization tower to acquire temperature information of the reaction chamber; The controller is electrically connected to both the sensor and the spray mechanism. The controller is used to start the spray mechanism when the temperature information is greater than a first threshold, or to stop the spray mechanism when the temperature information is less than a second threshold.

[0006] In an optional embodiment, the spraying mechanism includes a nozzle, a pipeline, a water pump, a first valve, and a water storage tank. One end of the pipeline is connected to the water storage tank, and the other end is connected to the nozzle. The water pump and the first valve are both located in the pipeline. Both the water pump and the first valve are electrically connected to the controller. The controller is used to start the water pump and the first valve when the temperature information is greater than a first threshold, or to close the water pump and the first valve when the temperature information is less than a second threshold.

[0007] In an optional embodiment, the desulfurization tower is provided with a spray chamber, which is connected to the reaction chamber and located at the top of the reaction chamber, and the nozzle is located in the spray chamber.

[0013] In an optional embodiment, the desulfurization tower is further provided with a discharge pipe and a second valve, the discharge pipe being connected to the bottom end of the reaction chamber, and the second valve being disposed on the discharge pipe.

A sensor installed on the desulfurization tower can acquire the temperature information inside the reaction chamber in real time and transmit the temperature signal to the controller. The controller establishes an electrical signal connection with both the sensor and the spray mechanism, and performs logical judgment based on the received temperature data: when the sensor detects that the temperature information inside the reaction chamber is greater than a first threshold, the controller automatically issues a start command to start the spray mechanism; when the temperature information drops to below a second threshold, the controller issues a stop command to stop the spray mechanism from operating. Therefore, the desulfurization device not only achieves precise control of the temperature inside the reaction chamber, but also effectively prevents thermal damage or accelerated aging of key equipment such as atomizers and seals due to local overheating.

[0025] Desulfurization units, as key equipment in industrial flue gas treatment systems, are widely used in thermal power generation, metallurgy, chemical industry, and other fields to remove sulfur oxides from flue gas and achieve environmentally friendly emissions. In actual operation, desulfurization processes often involve the input of high-temperature flue gas and complex chemical reactions, resulting in high internal temperatures. Although some equipment is equipped with insulation layers to maintain the reaction temperature, the sensors, actuators, electrical control modules, and some mechanical components installed inside are still exposed to high-temperature radiation and heat conduction environments for extended periods.

[0026] Because existing desulfurization devices generally lack effective heat dissipation designs or cooling structures, heat accumulates inside the equipment and is difficult to dissipate in a timely manner. This causes the operating temperature of key components to exceed their rated range, affecting their performance stability and response accuracy. For example, high temperatures can easily lead to accelerated aging of electronic components, deterioration of insulation material performance, thermal deformation or lubrication failure of mechanical parts, which in turn can cause equipment malfunctions, control failures, or sudden malfunctions, seriously reducing the reliability and safety of system operation.

[0027] In addition, the high temperature environment also makes daily inspection and maintenance operations difficult. Operators cannot approach the equipment for a long time to inspect and repair, which increases maintenance risks and downtime, and is not conducive to the continuous and stable operation of production.

[0028] Therefore, there is an urgent need to provide a desulfurization device structure with efficient heat dissipation function, improve the thermal management conditions of internal components, reduce operating temperature rise, enhance equipment reliability and maintainability, and ensure the long-term stable operation of the desulfurization system.

[0029] Please see Figure 1 and Figure 2 This utility model provides a desulfurization device 10, including a desulfurization tower 100, a spraying mechanism 200, a sensor 300 and a controller (not shown).

[0030] The desulfurization tower 100 is equipped with a reaction chamber 110, an inlet pipe 120, and an outlet pipe 130. Both the inlet pipe 120 and the outlet pipe 130 are connected to the reaction chamber 110. A spraying mechanism 200 is installed in the desulfurization tower 100 for spraying water into the reaction chamber 110. A sensor 300 is installed in the desulfurization tower 100 for acquiring temperature information of the reaction chamber 110. Both the sensor 300 and the spraying mechanism 200 are electrically connected to the controller. The controller is used to start the spraying mechanism 200 when the temperature information is greater than a first threshold, or to stop the spraying mechanism 200 when the temperature information is less than a second threshold.

[0031] It should be understood that the components in the desulfurization unit 10 work together to achieve effective control of the environment inside the reaction chamber 110.

[0032] In this embodiment, the desulfurization tower 100 is provided with a reaction chamber 110, an inlet pipe 120 and an outlet pipe 130. The inlet pipe 120 is used to introduce high-temperature flue gas containing sulfur dioxide into the reaction chamber 110, while the outlet pipe 130 is used to discharge the purified flue gas after the desulfurization reaction is completed. The reaction chamber 110 is the main space for the chemical reaction between flue gas and desulfurizing agent. The stability of its internal environment directly affects the desulfurization efficiency and the safety of equipment operation.

[0033] A spraying mechanism 200 is installed on the desulfurization tower 100 to spray water or desulfurization slurry into the reaction chamber 110. The droplets contact the flue gas to achieve cooling, preliminary dust removal, and desulfurization. A sensor 300 is installed on the desulfurization tower 100 to acquire real-time temperature information within the reaction chamber 110 and transmit this temperature signal to the controller. The controller establishes electrical signal connections with both the sensor 300 and the spraying mechanism 200. Based on the received temperature data, it performs logical judgments: when the sensor 300 detects that the temperature within the reaction chamber 110 is greater than a first threshold, the controller automatically issues a start command to activate the spraying mechanism 200; conversely, when the temperature drops below a second threshold, the controller issues a stop command to stop the spraying mechanism 200.

[0034] It should be noted that the first threshold and the second threshold mentioned here constitute a hysteresis control range, which is used to avoid the controller from frequently starting and stopping the spray mechanism 200 due to temperature fluctuations, thereby improving the stability and energy efficiency of the system operation.

[0035] In this embodiment, the start and stop of the spray mechanism 200 are dynamically adjusted by the controller based on the actual temperature, forming a closed-loop feedback control mechanism. This design not only achieves precise temperature control within the reaction chamber 110 but also effectively prevents thermal damage or accelerated aging of critical equipment such as the atomizer 400 and seals due to localized overheating. Simultaneously, in high-temperature and high-dust environments, continuous or intermittent spraying can reduce the concentration of dust in the air, minimizing the corrosive effects of accumulated dust on electrical components and rotating parts, further enhancing the reliability of equipment operation.

[0036] It can be seen that by combining the temperature information collected by the sensor 300 with the automatic control function of the controller, the spray mechanism 200 can intervene in time when necessary, which not only avoids unnecessary energy waste, but also ensures that the environment inside the desulfurization tower 100, especially the area where the atomizer 400 is located, is within a suitable range.

[0037] Based on the above design, the desulfurization unit 10, while ensuring the stable operation of the core process, significantly improves the thermal and cleanliness conditions of the key equipment, extends the service life of the equipment, and reduces the maintenance frequency and operating costs.

[0038] For example, the first threshold is greater than the second threshold; the first threshold could be 55℃, and the second threshold could be 45℃. In practical applications, when the local temperature in the top volute area of ​​the desulfurization tower 100 rises above 55℃ due to the continuous flow of high-temperature flue gas, the system can automatically activate the spray cooling program; and when the temperature drops below 45℃, the water spraying stops, maintaining the ambient temperature within a reasonable range, thus achieving the goals of energy-saving and intelligent environmental management. This can be understood as follows: without changing the original desulfurization process, this structural solution effectively solves the technical challenge posed by high-temperature and high-dust environments to the safe operation of core equipment in existing technologies by introducing a temperature sensing and automatic response mechanism.

[0039] Furthermore, the spraying mechanism 200 includes a nozzle 210, a pipeline 220, a water pump 230, a first valve 240, and a water storage tank 250. One end of the pipeline 220 is connected to the water storage tank 250, and the other end is connected to the nozzle 210. The water pump 230 and the first valve 240 are both located in the pipeline 220. The water pump 230 and the first valve 240 are both electrically connected to the controller. The controller is used to start the water pump 230 and the first valve 240 when the temperature information is greater than a first threshold, or to close the water pump 230 and the first valve 240 when the temperature information is less than a second threshold.

[0040] Specifically, the water pump 230 and the first valve 240 serve as the power and control execution units of the spraying mechanism 200. Their linkage response mechanism is uniformly scheduled by the controller. This design not only ensures the timeliness and controllability of the spraying process but also effectively prevents the risk of system malfunction due to the failure of a single component. Based on the above description, the entire spraying mechanism 200 forms a closed-loop control system consisting of perception, judgment, and execution, which can complete the tasks of monitoring and adjusting environmental parameters without human intervention.

[0041] Furthermore, the desulfurization tower 100 is provided with a spray chamber 140, which is connected to the reaction chamber 110 and located at the top of the reaction chamber 110, and the nozzle 210 is located in the spray chamber 140.

[0042] It can be seen that by arranging the nozzle 210 in the independently set spray chamber 140, the direct scouring of the nozzle 210 body and connecting parts by high temperature and high dust fumes is effectively isolated, reducing the risk of nozzle 210 clogging and wear, and extending its service life.

[0043] Based on the above description, the spray chamber 140 serves as a support and buffer space for the nozzle 210, protecting key components and providing good preconditions for the stable release of water mist.

[0044] For example, in practical applications, the top volute area of ​​the desulfurization tower 100 is in a high-temperature environment of 160-220℃ for a long time. If the nozzle 210 is directly exposed to the main airflow path, it is very easy to fail due to thermal stress concentration and ash and scale accumulation. However, after placing it in the spray chamber 140, since the spray chamber 140 itself does not directly receive the main flue flow, the working conditions of the nozzle 210 are significantly improved.

[0045] It is worth noting that there are multiple nozzles 210, which are arranged in a ring.

[0046] Therefore, by using multiple nozzles 210 arranged in a ring, the problems of local over-wetting or uneven spraying that may be caused by single-point spraying are avoided, and the uniformity of temperature control throughout the entire cross-section is improved.

[0047] The annular arrangement of nozzles 210 can establish a more stable heat exchange environment inside the desulfurization tower 100, which is especially suitable for the working conditions where flue gas enters tangentially from the inlet pipe 120 and forms a rotating flow. Therefore, in practical applications, after the high-temperature flue gas is introduced into the desulfurization tower 100 through the inlet pipe 120, it moves in a spiral along the volute structure. If only a single nozzle 210 is set, it is difficult to match the rotating path of the airflow, resulting in limited cooling effect. However, multiple annularly distributed nozzles 210 can work synergistically with the rotating flue gas, allowing the water mist to come into more full contact with the flue gas and enhancing the heat and mass transfer efficiency.

[0048] Moreover, multiple nozzles 210 are distributed in multiple layers along the height direction of the desulfurization tower 100, and multiple nozzles 210 in each layer are arranged in a ring.

[0049] It should be noted that the "multi-layer" mentioned here is defined as two or more nozzles 210 mounting planes spaced apart along the height direction of the desulfurization tower 100, with a certain distance between each layer to ensure that the water mist does not interfere with each other during the falling process, while continuously intercepting high-temperature flue gas at different height sections.

[0050] Therefore, when the water pump 230 starts and the first valve 240 opens, water from the water storage tank 250 is transported to each layer of nozzles 210 through the pipeline 220. Since each layer of nozzles 210 is distributed in a ring, the atomized droplets sprayed out achieve circumferential uniform coverage on the same horizontal cross section. The existence of the multi-layer structure makes the water mist form a stepped or curtain-like distribution pattern in the vertical direction and come into contact with the flue gas, absorbing heat step by step and reducing the dust concentration.

[0051] Furthermore, the desulfurization device 10 also includes an atomizer 400, which is disposed in the reaction chamber 110 and is used to spray atomized reaction liquid into the reaction chamber 110.

[0052] It should be noted that the "atomizer 400" mentioned here refers to a device that can break liquids into micron-sized droplets through high-speed rotation or other mechanical means. It is usually driven by an electric motor and equipped with a high-speed rotating wheel or centrifugal nozzle structure, and has the characteristics of high precision and strong stability.

[0053] Specifically, after the desulfurizing agent slurry is transported to the atomizer 400 via pipeline, the atomizer 400, rotating at 9000-13000 r / min, flings the slurry out and disperses it into a uniform fine mist. These droplets rapidly evaporate moisture in the hot flue gas environment and neutralize with SO2 to generate solid or semi-solid desulfurization products. Simultaneously, the cooling and dust suppression actions performed by the spray mechanism 200 directly affect the temperature and cleanliness level of the local environment surrounding the atomizer 400.

[0054] Furthermore, the desulfurization device 10 also includes an airflow channel 500, which is connected to the air inlet pipe 120. An atomizer 400 is disposed at the air outlet of the airflow channel 500, and a sensor 300 is disposed at the air inlet of the airflow channel 500.

[0055] When the high-temperature flue gas enters the airflow channel 500 through the inlet pipe 120, its initial temperature is first monitored in real time by the sensor 300. This temperature signal is then transmitted to the controller, serving as an important basis for determining whether to activate the spray mechanism 200. Since the sensor 300 is located at the inlet end of the airflow channel 500, it can sense the initial thermal state before the flue gas penetrates deep into the reaction chamber 110, thereby improving the timeliness and accuracy of the system response.

[0056] Meanwhile, the atomizer 400 is arranged at the outlet of the airflow channel 500, so that the fine droplets it sprays can enter the reaction chamber 110 synchronously with the airflow, forming pre-atomization and instant reaction process conditions in space.

[0057] It is worth mentioning that the airflow channel 500 is equipped with a spiral channel.

[0058] A “spiral channel” is defined as a flow path with a continuous curvature change, whose cross-section can be circular, rectangular or other adaptable shapes, and whose axial extension direction rotates and descends around the central axis, thereby guiding the flue gas to generate a circumferential velocity component.

[0059] Specifically, when the flue gas flows into the spiral channel through the inlet pipe 120, it is forced to move along the spiral path under the constraint of the channel wall, forming a flow field structure similar to cyclone flow. This rotating flow not only helps the flue gas to be evenly distributed across the cross-section of the reaction chamber 110, but also effectively avoids the occurrence of local airflow short-circuiting or deflection.

[0060] Therefore, by designing the airflow channel 500 as a spiral shape, the flow characteristics of the flue gas after entering the reaction chamber 110 are significantly improved. The rotating airflow still maintains a certain angular momentum when it leaves the outlet of the airflow channel 500, which can drive the atomized reaction liquid sprayed by the atomizer 400 to achieve a wider range of diffusion and mixing within the reaction chamber 110, thereby improving the contact efficiency between the gas and liquid phases.

[0061] Furthermore, the desulfurization tower 100 is also equipped with a discharge pipe 600 and a second valve 700. The discharge pipe 600 is connected to the bottom end of the reaction chamber 110, and the second valve 700 is located on the discharge pipe 600.

[0062] In this embodiment, the bottom of the reaction chamber 110 refers to the lowest region of the space inside the reaction chamber 110 of the desulfurization tower 100, which is the part where particulate matter naturally accumulates under the action of gravity settling.

[0063] Specifically, after the flue gas completes the desulfurization reaction in the reaction chamber 110, some of the larger desulfurization ash particles gradually settle to the bottom of the reaction chamber 110 due to gravity. If they are not discharged in time, they may cause problems such as material caking and pipe blockage, and even affect the operating space and heat dissipation conditions of the equipment below the atomizer 400.

[0064] Therefore, by setting up a discharge pipe 600 that is directly connected to the bottom of the reaction chamber 110, a smooth discharge path can be provided for these sediments. The second valve 700, as a control element installed on the discharge pipe 600, can be set to manual operation or remotely controlled by the controller according to the operating conditions, thereby realizing on-demand discharge.

[0065] Furthermore, the bottom of the reaction chamber 110 is provided with a cone-shaped deposition section 111, the discharge pipe 600 is connected to the end of the deposition section 111, the vent pipe 130 is connected to the deposition section 111, and the horizontal height of the vent pipe 130 is higher than the horizontal height of the end of the deposition section 111.

[0066] It can be understood that the cone-shaped deposition section 111, which is the funnel-shaped area formed by the inward contraction of the bottom of the reaction chamber 110, has a certain inclination angle on its inner wall, usually between 45° and 60°, so as to promote the smooth sliding of wet or dry desulfurization ash under the action of gravity and concentrate it at the inlet of the discharge pipe 600.

[0067] After the flue gas completes the desulfurization reaction in the reaction chamber 110, the dust and reaction products carried by it gradually adhere to the lower part of the chamber due to the decrease in speed and inertial settling during the flow process. The presence of the conical structure makes it difficult for these particles to accumulate and remain, but instead they converge towards the center along the slope and are periodically discharged through the discharge pipe 600.

[0068] Therefore, setting the connection point of the exhaust pipe 130 at a horizontal height higher than the end of the sedimentation section 111 effectively avoids the risk of sediment entering the exhaust pipe 130. Based on the above description, since the exhaust pipe 130 is used to guide the purified flue gas to the subsequent treatment system (such as a bag filter or denitrification device), if its inlet position is too low or located in the accumulation area, it may cause detached dust or agglomerated material to be drawn back into the pipe 220 with the airflow, causing channel blockage or equipment damage. By raising the connection point of the exhaust pipe 130, keeping it away from the main sedimentation area, only gas is allowed to pass through, while solid particles are restricted by the geometric structure to slide naturally to the lower discharge port, thereby achieving spatial isolation of gas-solid separation.

[0069] In summary, this utility model embodiment provides a desulfurization device 10. A spray mechanism 200 is installed on the desulfurization tower 100 to spray water or desulfurization slurry into the reaction chamber 110. The droplets contact the flue gas to achieve cooling, preliminary dust removal, and desulfurization. A sensor 300 is installed on the desulfurization tower 100 to acquire real-time temperature information within the reaction chamber 110 and transmit this temperature signal to the controller. The controller establishes electrical signal connections with both the sensor 300 and the spray mechanism 200. Based on the received temperature data, it performs logical judgments: when the sensor 300 detects that the temperature within the reaction chamber 110 is greater than a first threshold, the controller automatically issues a start command to activate the spray mechanism 200; when the temperature drops below a second threshold, the controller issues a stop command to stop the spray mechanism 200. Therefore, the desulfurization device 10 not only achieves precise temperature control within the reaction chamber 110 but also effectively prevents thermal damage or accelerated aging of critical equipment such as the atomizer 400 and seals due to localized overheating. Meanwhile, in high-temperature and high-dust environments, continuous or intermittent spraying can reduce the concentration of dust in the air, reduce the corrosion of electrical components and rotating parts by accumulated dust, and further improve the reliability of equipment operation.

[0070] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
