Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0061] This invention provides a flue gas latent heat recovery and utilization device with water collection and dust removal functions. Please refer to [link / reference]. Figures 1-7The system includes a recycling bin 10, the inner cavity of which is slidably connected to several corrugated plates 20 via a sliding assembly. The sliding assembly provides stable guidance for the movement of the corrugated plates 20, ensuring that the spacing and combination of multiple sets of corrugated plates 20 can be precisely adjusted. Moving components are provided between two sets of corrugated plates 20 and between the corrugated plates 20 and the recycling bin 10. These moving components allow for flexible addition, removal, and positioning of the corrugated plates 20, adapting to different flue gas treatment scale requirements. The inner cavity of each corrugated plate 20 is provided with a flow groove 21. The flow channel 21 provides a flow path for cooling water, enabling the corrugated plate 20 to form a high-efficiency heat exchange carrier. Both ends of the corrugated plate 20 are fixedly installed with flexible hoses 22 equipped with valves. One set of hoses 22 is connected to an external circulation pump to deliver cooling water to the flow channel 21, while the other set of hoses 22 is used for cooling water return. The valves can control the flow of cooling water through a single set of corrugated plates 20, facilitating maintenance or individual adjustment. The surface of the corrugated plate 20 has several guide grooves 23, which are irregularly shaped. The corrugated distribution enhances the turbulence of the flue gas within the flow channel, prolongs the flue gas residence time, and promotes the full collision and capture of droplets and dust with the surface of the corrugated plate 20, simultaneously achieving water collection, dust removal, and demisting functions. One end of the recovery box 10 is fixedly equipped with an inlet pipe 11 with a valve, which is used to connect the industrial flue gas to be treated. The valve controls the flue gas flow rate and its on / off state. The other end of the recovery box 10 is equipped with an outlet pipe 12 with a valve, which is used to discharge the treated clean gas. The height setting of the flue gas can reduce the backflow of unseparated pollutants. The bottom of the recovery box 10 is provided with several discharge holes 13, which are used to discharge captured dust, mist droplets, condensed water and other impurities for centralized collection and treatment. Several grooves 30 are provided on both sides of the corrugated plate 20, and a vibration motor 31 is fixedly installed in the grooves 30. When the vibration motor 31 is started, it can drive the corrugated plate 20 to generate slight vibration, which can prevent dust and impurities from scaling and accumulating on the surface of the corrugated plate 20, and ensure the stability of heat exchange and separation efficiency.

[0062] The sliding assembly includes: a slide groove 40, a slider 41, and a guide rod 42;

[0063] The top of the inner cavity of the recycling bin 10 is provided with several sliding grooves 40, which are distributed parallel to the length of the recycling bin 10 to provide a sliding track for the slider 41. The slider 41 is slidably connected in the sliding groove 40, and the top of the corrugated plate 20 is fixedly installed with the slider 41 by screws. The screw connection method facilitates the disassembly and replacement of the corrugated plate 20. The guide rod 42 is fixedly installed in the sliding groove 40, and the slider 41 is slidably connected to the guide rod 42. The guide rod 42 is set through the slider 41 to limit the sliding direction of the slider 41, avoid deviation, and ensure that the corrugated plate 20 moves smoothly.

[0064] The moving component includes: a storage slot 50, a fixing plate 51, a rotating shaft 52, a servo motor 53, an I-beam wheel 54, and a rope 55;

[0065] Several storage slots 50 are provided at the opposite ends of the two sets of corrugated plates 20 and at the opposite ends of the corrugated plates 20 and the recycling bin 10. The storage slots 50 are used to store the transmission components of the moving components, avoiding occupying the flue gas flow space or interfering with the flue gas flow. Fixing plates 51 are fixedly installed on both sides of the inner cavity of the storage slots 50. The fixing plates 51 provide stable support for the rotating shaft 52. The rotating shaft 52 is rotatably connected to the fixing plates 51 through bearings. The bearings can reduce the friction when the rotating shaft 52 rotates and improve the transmission efficiency. The servo motor 53 is fixedly installed on a set of fixing plates 51. 1. The output shaft of the servo motor 53 is fixedly connected to the rotating shaft 52. The servo motor 53 can precisely control the rotation angle and speed of the rotating shaft 52, thereby achieving precise winding and unwinding of the rope 55. The I-beam wheel 54 is fixedly installed between the two sets of rotating shafts 52. The I-beam wheel 54 is used to wind and store the rope 55 to ensure that the rope 55 is wound and unwinded in an orderly manner. The end of the rope 55 is fixedly installed on the I-beam wheel 54. The rope 55 is made of two strands of steel wire rope connected by a buckle. The steel wire rope has high strength, wear resistance and corrosion resistance. The buckle connection method facilitates the subsequent disassembly, replacement or maintenance of the rope 55.

[0066] The control system for the latent heat recovery and utilization equipment of flue gas with water collection and dust removal functions includes the aforementioned latent heat recovery and utilization equipment of flue gas with water collection and dust removal functions. Please refer to [link / reference needed]. Figure 8 It also includes:

[0067] The flue gas parameter sensing module is used to collect multi-dimensional raw data, and after preprocessing, classify and categorize it according to industry scenarios and operating condition fluctuation characteristics.

[0068] The central decision-making and control module is used to analyze core control requirements based on the scenario and operating condition classification results output by the flue gas parameter sensing module, combined with industry environmental protection standards, and to generate targeted control instructions by calling the strategy database.

[0069] The functional coordination execution module is used to receive the instruction allocation results from the central decision control module and adjust the plate group combination, flow channel parameters and cooling water conditions in a coordinated manner.

[0070] The status monitoring and feedback module is used to collect data on the equipment operating status and flue gas treatment effect of the functional collaborative execution module, and compare them with the preset target of the central decision control module to calculate the deviation value.

[0071] The adaptive optimization module is used to diagnose fault types and causes based on deviation data and operating status information from the status monitoring feedback module, correct control strategies in conjunction with real-time flue gas parameters from the sensing module, and iteratively optimize the strategy database through machine learning.

[0072] Please see Figure 9 The flue gas parameter sensing module includes:

[0073] The multi-dimensional sensing unit is used to deploy temperature sensors, humidity sensors, dust concentration sensors, flue gas flow sensors, and droplet size sensors to collect real-time raw data of flue gas temperature, relative humidity, dust concentration, flue gas flow, and droplet size, providing basic data for subsequent control.

[0074] The data preprocessing unit is used to remove interference noise by filtering algorithm (Kalman filtering) after receiving the raw data from the multi-dimensional sensing unit, and to identify and complete abnormal data (such as out-of-range data caused by sensor failure).

[0075] The parameter classification unit is used to analyze the industry scenario (thermal power / steel / chemical) of the flue gas based on the preprocessed data, and classify the operating conditions (stable operating conditions / fluctuating operating conditions / extreme operating conditions) according to dust concentration and flow fluctuation range, so as to provide the decision module with the basis for scenario adaptation.

[0076] Please see Figure 10 The central decision-making and control module includes:

[0077] The demand analysis unit is used to analyze the current core control requirements of the equipment (such as prioritizing adaptability under high flow fluctuation conditions) after receiving the scenario and working condition information from the parameter classification unit, combined with preset industry environmental protection standards (such as dust emission ≤10mg / m³, water absorption rate ≥98%).

[0078] The control strategy generation unit is used to generate targeted control instructions based on the requirements analysis results, by calling the built-in strategy database (which stores the optimal control parameter combinations for different scenarios and operating conditions), including instructions for adjusting the number of plate combinations, flow channel velocity control instructions, and cooling water temperature adjustment instructions. For example, when the operating condition is identified as a high dust concentration in the steel industry, a combination instruction of "adding 3 sets of plates, increasing the flow channel disturbance frequency, and reducing the cooling water temperature by 5°C" is generated.

[0079] The instruction allocation unit is used to allocate the generated control instructions to the corresponding units of the functional collaborative execution module according to the functional category, and at the same time record the instruction issuance time and parameter details to provide a basis for subsequent feedback verification.

[0080] Please see Figure 11 The functional collaborative execution module includes:

[0081] The panel group control unit is used to control the moving component after receiving the panel combination quantity adjustment instruction from the instruction allocation unit, so as to realize the addition, reduction and positioning of panels (e.g., when the flow rate is 400,000 m³ / h, it is adjusted to 12 panel combinations), and feed back the actual panel combination status to the status monitoring feedback module.

[0082] The flow channel parameter adjustment unit is used to adjust the flow channel cross-sectional area (e.g., when the number of plates increases, the flow channel cross-sectional area is simultaneously increased by 15%) according to the actual combination state of the plate group control unit, optimize the contact area between flue gas and cooling water, enhance the heat and mass transfer effect, and record the real-time parameters of the flow channel at the same time.

[0083] The medium circulation control unit is used to control the speed of the cooling water circulation pump and the valve opening according to the real-time parameters of the flow channel parameter adjustment unit, adjust the cooling water flow rate and temperature (e.g., increase the cooling water flow rate by 20% after the flow channel cross-sectional area is expanded), ensure the latent heat recovery efficiency, and monitor the cooling water quality (e.g., pH value, impurity content).

[0084] Please see Figure 12 The status monitoring feedback module includes:

[0085] The equipment operation status monitoring unit is used to collect equipment operation data in real time, such as the plate status of the plate group control unit, the flow resistance of the flow channel parameter adjustment unit, and the pump body operating temperature of the medium circulation control unit.

[0086] The treatment effect detection unit is used to deploy outlet flue gas detection sensors to collect dust concentration, droplet content, and flue gas temperature after the equipment is treated (to calculate latent heat recovery) and verify whether the water absorption rate, dust removal efficiency, and demisting efficiency meet the preset standards.

[0087] The data comparison and feedback unit is used to compare the actual results of the processing effect detection unit with the preset target of the central decision control module, calculate the deviation value (e.g., the actual dust removal efficiency is 92%, the preset target is 95%, and the deviation value is -3%), and synchronously feed the deviation data and equipment operation status data back to the central decision control module.

[0088] Please see Figure 13 The adaptive optimization module includes:

[0089] The fault diagnosis unit is used to receive deviation data and equipment operating status data from the status monitoring feedback module, and to identify the fault type and location based on the fault feature database (which includes typical fault features such as plate scaling and sensor failure). For example, when the flow channel resistance increases and the water recovery rate decreases by more than 3%, it is determined to be a plate scaling fault.

[0090] The parameter correction unit is used to correct the control strategy of the central decision control module based on the results of the fault diagnosis unit and the real-time flue gas parameters of the parameter classification unit; for example, when the plates are scaled, the cooling water temperature is adjusted to decrease by 8°C.

[0091] The strategy iteration unit records the running data and processing effect after each parameter correction, and optimizes the strategy database through machine learning algorithms. For example, it generates a unique combination of control parameters for specific flue gas parameters of a steel company, thereby realizing the self-iterative upgrade of the control strategy.

[0092] The specific implementation process of the control system is as follows:

[0093] Flue gas parameter acquisition and preprocessing: The multi-dimensional sensing unit of the flue gas parameter sensing module is deployed at the intake pipe 11 to collect real-time raw data of flue gas temperature, relative humidity, dust concentration, flue gas flow rate, droplet size, etc. The data preprocessing unit removes interference noise such as airflow disturbance and sensor error through Kalman filtering algorithm, identifies abnormal data that exceeds the normal range or changes abruptly, and completes the data based on valid data from adjacent time periods. The parameter classification unit determines the industry scenario of the flue gas (such as thermal power, steel, chemical) based on the characteristics of the preprocessed data, and classifies it into three levels: stable operating condition, fluctuating operating condition, and extreme operating condition according to the dust concentration and the magnitude of flow fluctuation.

[0094] Control Requirements Analysis and Command Generation: The requirements analysis unit of the central decision control module receives scenario and operating condition information from the parameter classification unit, and analyzes the current core control requirements in conjunction with preset industry environmental protection standards (such as dust emission limits, water recovery rate requirements, etc.). For example, in the stable operating conditions of the thermal power industry, priority is given to ensuring latent heat recovery efficiency, while in the high dust fluctuation conditions of the steel industry, priority is given to enhancing dust removal effect and equipment adaptability. Based on the requirements analysis results, the control strategy generation unit calls the built-in strategy database to generate targeted control commands, including parameter combinations such as the number of plate combinations, flow channel cross-sectional area, cooling water flow rate and temperature. The command allocation unit allocates the control commands to the corresponding units of the functional collaborative execution module according to functional categories, and records the command issuance time and parameter details.

[0095] Equipment Function Coordination Execution: After receiving the instruction, the plate group control unit of the function coordination execution module controls the servo motor 53 of the moving component to start. The servo motor 53 drives the rotating shaft 52 to rotate, and the I-beam wheel 54 rotates synchronously to realize the winding and unwinding of the rope 55. Then, through the slider 41 sliding along the slide groove 40 and the guide rod 42, it drives the corrugated plate 20 to move, realize the addition and reduction of plates and the adjustment of the spacing, and complete the plate group combination. The flow channel parameter adjustment unit automatically adjusts the flow channel cross-sectional area according to the actual combination state of the plate group to ensure that the flue gas velocity is in the optimal range and balance the separation efficiency and resistance loss. The medium circulation control unit controls the speed of the external circulation pump and the valve opening on the hose 22 according to the real-time data of the flow channel parameters, and adjusts the flow rate and temperature of the cooling water to form the best heat exchange temperature difference between the cooling water and the flue gas, thereby improving the latent heat recovery effect.

[0096] Status Monitoring and Feedback: The equipment operation status monitoring unit of the status monitoring and feedback module collects real-time equipment operation data such as the positioning accuracy of the plate group, flow resistance, operating temperature of servo motor 53, working status of vibration motor 31, and cooling water quality; the treatment effect detection unit is deployed at the exhaust pipe 12 to collect the dust concentration, droplet content, and flue gas temperature after treatment, calculate the water recovery rate, dust removal efficiency, demisting efficiency, and latent heat recovery, and verify whether the preset standards are met; the data comparison and feedback unit compares the actual treatment effect with the preset target of the central decision control module, calculates the deviation value, and synchronously feeds back the deviation data and equipment operation status data to the central decision control module and the adaptive optimization module.

[0097] Adaptive optimization of control strategy: The fault diagnosis unit of the adaptive optimization module receives deviation data and equipment operating status data. Based on the built-in fault feature database, it identifies the fault type and location. For example, excessive dust removal efficiency deviation may be due to plate scaling or insufficient plate combination. Low latent heat recovery efficiency may be due to excessively high cooling water temperature or unsuitable flow channel cross-sectional area. The parameter correction unit, based on the fault diagnosis results and combined with the real-time flue gas parameters from the parameter classification unit, corrects the control strategy of the central decision control module. For example, when plates are scaled, the vibration motor 31 is started to clean the scale and the cooling water temperature is adjusted. When the plate combination is insufficient, the number of plates is increased. The strategy iteration unit records the operating data and processing effect after each parameter correction. Through machine learning algorithms, it continuously optimizes the strategy database, so that the control strategy gradually adapts to the flue gas treatment needs of specific industries and specific working conditions, achieving long-term performance improvement.

[0098] In practical use, those skilled in the art can preset parameters such as industry type and environmental protection standards through the human-machine interface of the control system according to the actual application scenario, and the equipment can automatically operate according to the above process without frequent manual intervention; when maintenance is required, the corresponding valve can be closed, the buckle of the hose 22 or the screw on the top of the corrugated plate 20 can be removed to realize the inspection and maintenance of individual components.

[0099] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
