Description

Technical Field

[0001] This invention relates to the field of dehumidification and desiccation technology, and more specifically, to a condensation control method and system for a composite dehumidification and desiccation device. Background Technology

[0002] During industrial production, the emission of large amounts of humid waste gas can produce a "white plume" phenomenon, which not only affects the aesthetics of the environment but may also cause environmental problems such as smog and acid rain. At the same time, waste gas with excessive humidity can also corrode subsequent treatment equipment and reduce its service life.

[0003] Traditional dehumidification and whitening devices often operate with fixed parameters, making it difficult to flexibly adjust their operation based on actual waste gas conditions. This results in low treatment efficiency and significant energy waste. When waste gas flow changes, the fixed water output from the water curtain spray and the compressor power may lead to excessive water consumption or insufficient dehumidification. Furthermore, the inability to dynamically adjust the compressor power to handle waste gas with varying initial temperatures makes the equipment inadequate for high-temperature waste gas treatment and results in energy redundancy for low-temperature waste gas treatment.

[0004] Therefore, it is necessary to provide a condensation control method and system for a composite dehumidification and desiccation device to solve the problem of low treatment efficiency and energy waste caused by the traditional dehumidification and desiccation device using a fixed parameter operation mode, which makes it difficult to flexibly adjust according to the exhaust gas conditions. Summary of the Invention

[0005] In view of this, the present invention proposes a condensation control method and system for a composite dehumidification and desiccation device, which aims to solve the problem that traditional dehumidification and desiccation devices, due to their fixed parameter operation mode, are difficult to adjust flexibly according to the exhaust gas conditions, resulting in low treatment efficiency and energy waste.

[0006] On the one hand, this invention proposes a condensation control method for a composite dehumidification and whitening device, comprising:

[0007] Obtain exhaust gas parameters; wherein, the exhaust gas parameters include exhaust gas flow rate, initial exhaust gas temperature, and exhaust gas temperature after condensation through the condensation structure;

[0008] The initial water output of the water curtain spray device and the initial power of the compressor corresponding to the condensing structure are controlled according to the exhaust gas flow rate.

[0009] Determine whether to adjust the initial power based on the initial temperature of the exhaust gas. If it is determined that adjustment is needed, adjust the initial power based on historical data and the initial temperature limit to obtain the adjusted power.

[0010] Obtain the current compressor power, calculate the temperature difference between the condensed temperature of the exhaust gas and the initial temperature of the exhaust gas, obtain several temperature difference values ​​within a preset time period, calculate the average value of the temperature difference values, and determine whether to adjust the current compressor power and the initial water output based on the average value of the temperature difference values.

[0011] If it is determined that the current compressor power and initial water output need to be adjusted, a stable difference value is calculated using several temperature differences and their average value. The initial power and initial water output are then adjusted based on the stable difference value to obtain the final power value and final water output value.

[0012] Furthermore, when controlling the initial water output of the water curtain spray device and the initial power of the compressor corresponding to the condensing structure based on the exhaust gas flow rate, the following steps are included:

[0013] Obtain the final value of historical water output and the final value of historical power corresponding to the exhaust gas flow rate in the historical data, and calculate the average value of the final value of historical water output and the average value of the final value of historical power respectively;

[0014] The average of the final historical water output is used as the initial water output, and the average of the final historical power is used as the initial power.

[0015] Furthermore, when determining whether to adjust the initial power based on the initial temperature of the exhaust gas, the following steps are included:

[0016] An initial exhaust gas temperature limit is preset. If the initial exhaust gas temperature is greater than the initial exhaust gas temperature limit, it is determined that the initial power needs to be adjusted.

[0017] Otherwise, it is determined that no adjustment to the initial power is required.

[0018] Furthermore, when adjusting the initial power based on historical data and the initial temperature limit to obtain the adjusted power, the process includes:

[0019] Calculate the initial temperature difference between the initial temperature of the exhaust gas and the initial temperature limit value of the exhaust gas;

[0020] A first difference and a second difference are set, wherein the first difference is less than the second difference and the first difference is greater than the initial temperature difference;

[0021] If the initial temperature difference is less than the first difference but greater than the initial temperature difference limit, the initial power is adjusted by the first adjustment coefficient.

[0022] If the initial temperature difference is greater than or equal to the first difference and less than the second difference, the initial power is adjusted by the second adjustment coefficient.

[0023] If the initial temperature difference is greater than the second difference, the initial power is adjusted by a third adjustment coefficient;

[0024] The adjustment coefficient ranges from 1 to 1.5, and the adjusted power is the product of the initial power and the adjustment coefficient.

[0025] Furthermore, the process of obtaining the current compressor power, calculating the temperature difference between the condensed temperature of the exhaust gas and the initial temperature of the exhaust gas, obtaining several temperature difference values ​​within a preset time period, and calculating the average value of the temperature difference values ​​includes:

[0026] The current compressor power is either the initial power or the adjusted power; wherein, if the initial power has not been adjusted, the current compressor power is the initial power, and if the initial power has been adjusted, the current compressor power is the adjusted power.

[0027] Several sampling time points are set within a preset time period, the temperature difference at each sampling time point is calculated, and the average value of the difference is calculated based on the several temperature differences.

[0028] Furthermore, when determining whether to adjust the current compressor power and initial water output based on the average difference, the following steps are included:

[0029] A first temperature difference limit and a second temperature difference limit are set, wherein the first temperature difference limit is less than the second temperature difference limit;

[0030] If the average difference is greater than the second temperature difference limit, it is determined that the current compressor power and initial water output need to be adjusted.

[0031] If the average value of the difference is less than or equal to the second temperature difference limit and greater than or equal to the first temperature difference limit, then it is determined that only the current compressor power needs to be adjusted.

[0032] If the average difference is less than the first temperature difference limit, it is determined that no adjustment is needed to the current compressor power and initial water output.

[0033] Furthermore, when calculating the stable value of the difference using the plurality of temperature differences and the average value of the differences, the process includes:

[0034] The standard deviation of the temperature difference is calculated using the following formula:

[0035]

[0036] In the above formula, σ represents the standard deviation, N represents the total number of temperature difference values, i represents the i-th temperature difference value, and Ti represents the i-th temperature difference value. This represents the average of the differences;

[0037] The standard deviation is used as the stable value of the difference.

[0038] Furthermore, when adjusting the initial power and initial water output based on the stable difference value, the following steps are included:

[0039] When it is determined that the current compressor power and initial water output need to be adjusted, a stable value limit value is set;

[0040] If the stable difference value is greater than or equal to the stable value threshold, the current compressor power is adjusted using a first adjustment coefficient, and the initial water output is adjusted using a second adjustment coefficient; if the stable difference value is less than the stable value threshold, the current compressor power is adjusted using a third adjustment coefficient, and the initial water output is adjusted using a fourth adjustment coefficient.

[0041] Wherein, 1 < third adjustment coefficient < first adjustment coefficient < 1.5; 1 < fourth adjustment coefficient < second adjustment coefficient < 1.5; and the final power value is the product of the current compressor power and the first or third adjustment coefficient, and the final water output value is the product of the initial water output and the second or fourth adjustment coefficient.

[0042] Furthermore, when adjusting the initial power and initial water output based on the stable difference value, the method further includes:

[0043] When it is determined that only the current compressor power needs to be adjusted, if the stable difference value is greater than or equal to the stable value limit value, the current compressor power is adjusted by the first correction coefficient.

[0044] If the stable difference value is less than the stable value limit value, the current compressor power is adjusted by the second correction coefficient;

[0045] Wherein, 1 < second correction coefficient < first correction coefficient < 1.3, and the final power value is the product of the current compressor power and the first correction coefficient or the second correction coefficient.

[0046] Compared with existing technologies, the advantages of this invention are as follows: First, in the parameter acquisition stage, comprehensive data collection of exhaust gas flow rate, initial temperature, and post-condensation temperature provides a rich data foundation for subsequent precise control. Determining the initial water output of the water curtain spray device and the initial power of the compressor based on the exhaust gas flow rate ensures a relatively reasonable operating state from the initial stage, avoiding energy waste and inefficiency. Judging whether to adjust the initial power based on the initial exhaust gas temperature, and dynamically adjusting using historical data and initial temperature limits, adapts to changes in exhaust gas temperature under different operating conditions, ensuring efficient operation even when treating high-temperature exhaust gas. Calculating the temperature difference and its average value to determine adjustment needs effectively captures temperature change trends during operation, avoiding erroneous adjustments due to local fluctuations and ensuring the scientific nature and stability of the adjustment strategy. When adjustment is required, calculating the stable value of the temperature difference further optimizes the initial power and water output, comprehensively considering the dispersion of temperature changes, making the final determined power and water output values ​​more closely match actual needs, achieving refined control. Overall, this method achieves closed-loop control from initial parameter setting to dynamic adjustment, which can flexibly adjust the equipment operating status according to the actual parameters of the exhaust gas, improve the treatment efficiency and energy utilization of the composite whitening and dehumidification device, reduce operating costs, and ensure the stable and reliable operation of the device.

[0047] On the other hand, this application also provides a condensation control system for a composite dehumidification and whitening device, comprising:

[0048] The acquisition module is configured to acquire exhaust gas parameters, including exhaust gas flow rate, initial exhaust gas temperature, and exhaust gas temperature after condensation through the condensation structure.

[0049] The initial parameter setting module is configured to control the initial water output of the water curtain spray device and the initial power of the compressor corresponding to the condensing structure based on the exhaust gas flow rate.

[0050] The preliminary adjustment module is configured to determine whether to adjust the initial power based on the initial temperature of the exhaust gas. If it is determined that adjustment is needed, the initial power is adjusted based on historical data and the initial temperature limit to obtain the adjusted power.

[0051] The judgment module is configured to obtain the current compressor power, calculate the temperature difference between the temperature of the condensed exhaust gas and the initial temperature of the exhaust gas, obtain several temperature difference values ​​within a preset time period, calculate the average value of the temperature difference values, and determine whether to adjust the current compressor power and the initial water output based on the average value of the temperature difference values.

[0052] The readjustment module is configured to, if it is determined that the current compressor power and initial water output need to be adjusted, calculate a stable difference value using several temperature differences and the average of the differences, and adjust the initial power and initial water output based on the stable difference value to obtain the final power value and the final water output value.

[0053] It is understood that the condensation control method and system of the composite dehumidification and desiccation device provided in this application have the same beneficial effects, and will not be described in detail here. Attached Figure Description

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0058] In some embodiments of this application, see Figure 1 As shown, this embodiment provides a condensation control method for a composite dehumidification and whitening device, including the following steps:

[0059] S100. Obtain exhaust gas parameters; wherein, the exhaust gas parameters include exhaust gas flow rate, initial exhaust gas temperature, and exhaust gas temperature after condensation through the condensation structure;

[0060] S200. Control the initial water output of the water curtain spray device and the initial power of the compressor corresponding to the condensing structure according to the exhaust gas flow rate.

[0061] S300. Determine whether to adjust the initial power based on the initial temperature of the exhaust gas. If it is determined that adjustment is needed, adjust the initial power based on historical data and the initial temperature limit to obtain the adjusted power.

[0062] S400: Obtain the current compressor power, calculate the temperature difference between the condensed temperature of the exhaust gas and the initial temperature of the exhaust gas, obtain several temperature differences within a preset time period, calculate the average value of the temperature differences, and determine whether to adjust the current compressor power and the initial water output based on the average value of the temperature differences.

[0063] S500. If it is determined that the current compressor power and initial water output need to be adjusted, a stable difference value is calculated using several temperature differences and the average value of the differences. The initial power and initial water output are adjusted according to the stable difference value to obtain the final power value and the final water output value.

[0064] Understandably, the first step in parameter acquisition involves comprehensively collecting data on exhaust gas flow rate, initial temperature, and post-condensation temperature to provide a rich data foundation for subsequent precise control. Determining the initial water output of the water curtain spray device and the initial power of the compressor based on the exhaust gas flow rate ensures a relatively reasonable operating state from the outset, avoiding energy waste and inefficiency. The initial power is adjusted based on the initial exhaust gas temperature, using historical data and initial temperature limits for dynamic adjustment. This adapts to changes in exhaust gas temperature under different operating conditions, ensuring efficient operation even when treating high-temperature exhaust gases. Calculating temperature differences and their average values ​​to determine adjustment needs effectively captures temperature change trends during operation, avoiding erroneous adjustments due to local fluctuations and ensuring the scientific validity and stability of the adjustment strategy. When adjustments are needed, the initial power and water output are further optimized by calculating the stable value of the temperature difference. This comprehensive consideration of the dispersion of temperature changes ensures that the final power and water output values ​​better match actual requirements, achieving refined control. Overall, this method achieves closed-loop control from initial parameter setting to dynamic adjustment, which can flexibly adjust the equipment operating status according to the actual parameters of the exhaust gas, improve the treatment efficiency and energy utilization of the composite whitening and dehumidification device, reduce operating costs, and ensure the stable and reliable operation of the device.

[0065] Specifically, the composite dehumidification device in this invention is the composite dehumidification device in the composite dehumidification device with application number 202210377656.X.

[0066] In some embodiments of this application, controlling the initial water output of the water curtain spray device and the initial power of the compressor corresponding to the condensing structure based on the exhaust gas flow rate includes:

[0067] Obtain the final value of historical water output and the final value of historical power corresponding to the exhaust gas flow rate in the historical data, and calculate the average value of the final value of historical water output and the average value of the final value of historical power respectively;

[0068] The average of the final historical water output is used as the initial water output, and the average of the final historical power is used as the initial power.

[0069] It is understood that, in the embodiments of this application, by collecting and analyzing the historical final values ​​of effluent flow and historical final values ​​of power corresponding to the current exhaust gas flow rate, and calculating their average value as the initial operating parameters, past successful operating experience can be fully utilized. Historical data contains information on the optimal operating state of the device under different operating conditions. Using this data can avoid blindly experimenting in new control cycles, allowing the device to approach the optimal operating point from the outset. This method not only improves response speed and reduces adjustment time in the initial stage, but also reduces energy waste and equipment wear caused by improper parameter settings. Furthermore, the statistical averaging of historical data can effectively smooth out the influence of random factors, making the initial parameters more representative and stable, providing a solid foundation for subsequent dynamic adjustments, thereby improving the operating efficiency and reliability of the entire composite dehumidification and whitening device.

[0070] In some embodiments of this application, determining whether to adjust the initial power based on the initial temperature of the exhaust gas includes:

[0071] An initial exhaust gas temperature limit is preset. If the initial exhaust gas temperature is greater than the initial exhaust gas temperature limit, it is determined that the initial power needs to be adjusted.

[0072] Otherwise, it is determined that no adjustment to the initial power is required.

[0073] In some embodiments of this application, adjusting the initial power based on historical data and an initial temperature limit to obtain the adjusted power includes:

[0074] Calculate the initial temperature difference between the initial temperature of the exhaust gas and the initial temperature limit value of the exhaust gas;

[0075] A first difference and a second difference are set, wherein the first difference is less than the second difference and the first difference is greater than the initial temperature difference;

[0076] If the initial temperature difference is less than the first difference but greater than the initial temperature difference limit, the initial power is adjusted by the first adjustment coefficient.

[0077] If the initial temperature difference is greater than or equal to the first difference and less than the second difference, the initial power is adjusted by the second adjustment coefficient.

[0078] If the initial temperature difference is greater than the second difference, the initial power is adjusted by a third adjustment coefficient;

[0079] The adjustment coefficient ranges from 1 to 1.5, and the adjusted power is the product of the initial power and the adjustment coefficient.

[0080] Understandably, this invention avoids over-adjustment of exhaust gas at normal temperatures and reduces unnecessary energy consumption by setting a temperature limit as a trigger threshold. The corresponding design of the three-level difference range and adjustment coefficient enables a refined response to different temperature deviations: smaller deviations are fine-tuned with a smaller coefficient to ensure stability; medium deviations are adjusted with a moderate coefficient to balance energy efficiency and performance; and larger deviations are responded to quickly with a larger coefficient to ensure processing efficiency. The range constraint of the adjustment coefficient (1-1.5) prevents energy waste caused by over-adjustment while ensuring processing capacity under high-temperature conditions. This graded adjustment mechanism allows the system to dynamically match the optimal power according to the exhaust gas temperature, significantly improving energy utilization efficiency and extending equipment life compared to the traditional fixed power mode, while ensuring stable and efficient whitening and dehumidification effects under different operating conditions.

[0081] In some embodiments of this application, the steps of obtaining the current compressor power, calculating the temperature difference between the condensed temperature of the exhaust gas and the initial temperature of the exhaust gas, obtaining several temperature difference values ​​within a preset time period, and calculating the average value of the temperature difference values ​​include:

[0082] The current compressor power is either the initial power or the adjusted power; wherein, if the initial power has not been adjusted, the current compressor power is the initial power, and if the initial power has been adjusted, the current compressor power is the adjusted power.

[0083] Several sampling time points are set within a preset time period, the temperature difference at each sampling time point is calculated, and the average value of the difference is calculated based on the several temperature differences.

[0084] In some embodiments of this application, determining whether to adjust the current compressor power and initial water output based on the average difference includes:

[0085] A first temperature difference limit and a second temperature difference limit are set, wherein the first temperature difference limit is less than the second temperature difference limit;

[0086] If the average difference is greater than the second temperature difference limit, it is determined that the current compressor power and initial water output need to be adjusted.

[0087] If the average value of the difference is less than or equal to the second temperature difference limit and greater than or equal to the first temperature difference limit, then it is determined that only the current compressor power needs to be adjusted.

[0088] If the average difference is less than the first temperature difference limit, it is determined that no adjustment is needed to the current compressor power and initial water output.

[0089] Understandably, at the data acquisition level, clearly identifying the source of the current compressor power (initial or adjusted) and calculating the average temperature difference at multiple sampling points within a preset time period effectively filters out instantaneous fluctuations, making the data more reflective of the system's true operating trend. At the adjustment decision level, a three-level response range is defined by setting dual temperature difference limits (first and second): when the average difference exceeds the second limit, it is determined that power and water output need to be adjusted simultaneously to address significantly deviating from the target; when it is between the two limits, power fine-tuning is focused on optimizing energy efficiency; and when it is below the first limit, the current parameters are maintained to avoid over-adjustment. This tiered response mechanism avoids the arbitrariness of a single threshold judgment and enhances the scientific nature of the decision-making through the combination of "mean + range." The mean eliminates random errors, and the range division matches different adjustment intensities, achieving a balance between stability and response speed.

[0090] In some embodiments of this application, the step of calculating the stable value of the difference using a plurality of temperature differences and the average value of the differences includes:

[0091] The standard deviation of the temperature difference is calculated using the following formula:

[0092]

[0093] In the above formula, σ represents the standard deviation, N represents the total number of temperature difference values, i represents the i-th temperature difference value, and Ti represents the i-th temperature difference value. This represents the average of the differences;

[0094] The standard deviation is used as the stable value of the difference.

[0095] In some embodiments of this application, adjusting the initial power and initial water output based on the stable difference value includes:

[0096] When it is determined that the current compressor power and initial water output need to be adjusted, a stable value limit value is set;

[0097] If the stable difference value is greater than or equal to the stable value threshold, the current compressor power is adjusted using a first adjustment coefficient, and the initial water output is adjusted using a second adjustment coefficient; if the stable difference value is less than the stable value threshold, the current compressor power is adjusted using a third adjustment coefficient, and the initial water output is adjusted using a fourth adjustment coefficient.

[0098] Wherein, 1 < third adjustment coefficient < first adjustment coefficient < 1.5; 1 < fourth adjustment coefficient < second adjustment coefficient < 1.5; and the final power value is the product of the current compressor power and the first or third adjustment coefficient, and the final water output value is the product of the initial water output and the second or fourth adjustment coefficient.

[0099] In some embodiments of this application, when adjusting the initial power and initial water output based on the stable difference value, the method further includes:

[0100] When it is determined that only the current compressor power needs to be adjusted, if the stable difference value is greater than or equal to the stable value limit value, the current compressor power is adjusted by the first correction coefficient.

[0101] If the stable difference value is less than the stable value limit value, the current compressor power is adjusted by the second correction coefficient;

[0102] Wherein, 1 < second correction coefficient < first correction coefficient < 1.3, and the final power value is the product of the current compressor power and the first correction coefficient or the second correction coefficient.

[0103] Understandably, this invention achieves quantitative control and intelligent response to fluctuations by introducing standard deviation as a stability indicator and constructing a hierarchical adjustment mechanism. Using standard deviation to measure the dispersion of temperature differences allows for precise capture of system stability; a larger standard deviation indicates severe fluctuations requiring stronger intervention, while a smaller standard deviation reflects system stability, necessitating fine-tuning. In the dual-adjustment strategy, for scenarios requiring simultaneous adjustment of power and water output, fluctuation intensity is differentiated by stability thresholds, employing different combinations of adjustment coefficients (first / third adjustment coefficients corresponding to power, second / fourth adjustment coefficients corresponding to water output) to ensure rapid response under high-intensity fluctuations and precise control under low-intensity fluctuations. In scenarios requiring only power adjustment, the correction coefficients (first / second correction coefficients) are further refined, ensuring both hierarchical adjustment intensity and avoiding over-adjustment through coefficient range constraints. This intelligent decision-making mechanism based on data statistical characteristics can dynamically adapt to changes in operating conditions: proactively enhancing processing capacity when exhaust gas parameters fluctuate significantly, and optimizing energy efficiency under stable conditions. Compared to traditional fixed-parameter control, it significantly improves system anti-interference capability and operating efficiency. For example, when the standard deviation exceeds the limit value, the power and water output adjustment range are automatically increased to quickly suppress fluctuations; while when the standard deviation is low, a gentle correction is used to avoid parameter oscillations and extend the service life of the equipment.

[0104] On the other hand, see Figure 2 As shown, this application also provides a condensation control system for a composite dehumidification and moisture removal device, used for applying the condensation control method of the above-mentioned composite dehumidification and moisture removal device, including:

[0105] The acquisition module is configured to acquire exhaust gas parameters, including exhaust gas flow rate, initial exhaust gas temperature, and exhaust gas temperature after condensation through the condensation structure.

[0106] The initial parameter setting module is configured to control the initial water output of the water curtain spray device and the initial power of the compressor corresponding to the condensing structure based on the exhaust gas flow rate.

[0107] The preliminary adjustment module is configured to determine whether to adjust the initial power based on the initial temperature of the exhaust gas. If it is determined that adjustment is needed, the initial power is adjusted based on historical data and the initial temperature limit to obtain the adjusted power.

[0108] The judgment module is configured to obtain the current compressor power, calculate the temperature difference between the temperature of the condensed exhaust gas and the initial temperature of the exhaust gas, obtain several temperature difference values ​​within a preset time period, calculate the average value of the temperature difference values, and determine whether to adjust the current compressor power and the initial water output based on the average value of the temperature difference values.

[0109] The readjustment module is configured to, if it is determined that the current compressor power and initial water output need to be adjusted, calculate a stable difference value using several temperature differences and the average of the differences, and adjust the initial power and initial water output based on the stable difference value to obtain the final power value and the final water output value.

[0110] Understandably, this invention breaks down the control logic into five functional modules: acquisition, setting, adjustment, judgment, and readjustment, achieving closed-loop management of the entire process from data acquisition to dynamic control. The acquisition module accurately acquires core parameters of the exhaust gas, providing real-time data support for subsequent decision-making. The initial parameter setting module calls historical data averages based on exhaust gas flow, ensuring the system is in an optimized initial state from startup, reducing losses from blind debugging. The preliminary adjustment module constructs a threshold trigger mechanism for the initial exhaust gas temperature, combining historical data and grading coefficients to achieve intelligent pre-adjustment of power, responding in advance to temperature changes. The judgment module uses multi-sampling point average calculation and dual threshold interval division to hierarchically identify system operational deviations, avoiding misjudgments based on single indicators and improving the scientific nature of decision-making. The readjustment module introduces standard deviation as a stability indicator, dynamically matching adjustment coefficients according to fluctuation intensity to achieve refined correction of power and water output. It provides strong intervention and rapid system stabilization during high-intensity fluctuations, and fine-tunes to optimize energy efficiency during low-intensity fluctuations.

[0111] Furthermore, the hierarchical control mechanism achieves a multi-stage response of "data acquisition - preliminary prediction - dynamic correction," progressively optimizing control accuracy and making it easier to locate and resolve anomalies compared to traditional integrated control. Secondly, the combination of historical data and real-time feedback retains mature operating experience while dynamically calibrating according to current operating conditions, balancing stability and adaptability. Simultaneously, the introduction of quantitative indicators (mean, standard deviation, and coefficient range) makes the control process traceable and optimizable, providing a data foundation for subsequent system performance iterations. Through structured design and intelligent strategies, this system significantly improves the dynamic adaptability of the composite whitening and dehumidification device to complex exhaust gas conditions, minimizing energy consumption and equipment wear while ensuring whitening and dehumidification efficiency.

Several sampling time points are set within the preset time period, the temperature difference at each sampling time point is calculated, and the result is determined based on the average temperature difference. The average temperature difference is calculated. A first temperature difference limit and a second temperature difference limit are set, where the first temperature difference limit is less than the second temperature difference limit. If the average temperature difference is greater than the second temperature difference limit, it is determined that the current compressor power and initial water output need to be adjusted. If the average temperature difference is less than or equal to the second temperature difference limit and greater than or equal to the first temperature difference limit, it is determined that only the current compressor power needs to be adjusted. If the average temperature difference is less than the first temperature difference limit, it is determined that no adjustment is needed to the current compressor power and initial water output. If it is determined that the current compressor power and initial water output need to be adjusted, then a stable value of the temperature difference is calculated using several temperature difference values ​​and their average value, including: calculating the standard deviation of the temperature difference using the following formula: In the above formula, σ represents the standard deviation, N represents the total number of temperature difference values, and Ti represents the i-th temperature difference value. The average value of the difference is represented; the standard deviation is taken as the stable value of the difference. The current compressor power and initial water output are adjusted based on the stable difference value to obtain the final power value and final water output value.
