[0035] In a feasible implementation, before the heat energy closed-loop recycling is prepared to be carried out, it is ensured that all related devices (such as a dryer, a heat energy recycling device, etc.) are in good condition; according to the first characteristic index and the second characteristic index, the heat energy recycling layer is pre-configured.

[0036] In a feasible implementation, the heat energy closed-loop recycling system is started, and the heat energy recycling layer starts to work; when the drying process is carried out, various parameters in the drying process are recorded in real time, such as real-time drying temperature, real-time hot air drying air flow, etc.; after the drying is completed, the first drying quality is evaluated; then, the first drying quality is compared with the initial drying quality; if the first drying quality meets the preset ideal drying quality standard, it is indicated that the configuration of the heat energy recycling layer is effective, and no adjustment is needed; if the first drying quality is degraded (that is, does not meet the preset ideal drying quality standard), the next adjustment needs to be carried out.

[0038] Further, the first heat energy recycling module M200 is also used to execute the following method: Taking the first drying quality as a starting point, the initial drying quality is taken as a screening condition, and a drying quality-heat energy utilization rate mapping sequence of the heat energy recycling layer is established; based on the drying quality-heat energy utilization rate mapping sequence, a loop iteration is carried out until the preset ideal drying quality standard is met.

[0039] The heat energy recycling rate corresponding to the drying process of the last vehicle component cleaning and drying cycle is updated, specifically, the initial drying quality is defined, the initial drying quality refers to the quality state of the vehicle component before heat energy recycling when the drying process starts, including its water content, surface state, etc.; the preset ideal drying quality standard is defined, the preset ideal drying quality standard refers to the comparison of different vehicle component product requirements and drying process settings, including dryness, color, particle size, etc.

The initial drying quality is used as a screening condition to distinguish the heat energy utilization under different drying quality conditions. Based on a large amount of actual drying data and experimental data, a corresponding relationship between the drying quality (such as moisture content, temperature, etc.) and the heat energy utilization rate is established to form the drying quality-heat energy utilization rate mapping sequence. The drying quality-heat energy utilization rate mapping sequence describes the effective utilization degree of heat energy under different drying quality conditions.

[0041] According to the current drying quality, the corresponding heat energy utilization rate is found in the mapping sequence, and then the working parameters (such as temperature, air speed, etc.) of the drying equipment are adjusted according to the utilization rate to optimize the heat energy utilization. In the iteration process, the change of the drying quality is constantly monitored and compared with the preset ideal drying quality standard. If the current drying quality does not meet the standard, the iteration continues. If it meets or exceeds the standard, the iteration stops. When the drying quality meets the preset ideal drying quality standard, the iteration process is terminated. After the iteration is completed, the heat energy reutilization rate data corresponding to the drying process is updated according to the final drying quality and heat energy utilization rate.

[0042] In actual application process, it also includes applying the updated heat energy reutilization rate data in actual production process to monitor the heat energy utilization of the drying process; adjusting the drying process parameters or the heat energy recovery system according to the monitoring results to further improve the heat energy reutilization rate and the drying efficiency; regularly collecting and analyzing the heat energy utilization data of the drying process to identify potential problems and improvement points, continuously optimizing the heat energy recovery system and the drying process to improve the overall energy efficiency and product quality.

[0043] Further, the second heat energy recovery module M300 is used to execute the following method: The first historical cleaning liquid temperature, the first historical cleaning liquid flow rate, and the first historical cleaning running power corresponding to the cleaning process of the current vehicle component cleaning and drying cycle are recorded. The third characteristic index is set by the ratio of the first historical cleaning liquid temperature and the first historical cleaning liquid flow rate. The fourth characteristic index is set by the first historical cleaning running power and the corresponding time sequence information. Based on the third characteristic index and the fourth characteristic index, the heat energy recovery layer.

[0044] The heat energy recovery The first historical cleaning liquid temperature, i.e., the temperature of the cleaning liquid used during the cleaning process, reflects the thermal energy state of the cleaning liquid; the first historical cleaning liquid flow rate, i.e., the flow rate of the cleaning liquid, reflects the usage amount and cleaning efficiency of the cleaning liquid; and the first historical cleaning operation power, i.e., the power of the cleaning equipment during operation, is directly related to energy consumption and cleaning efficiency.

[0045] Preferably, a third characteristic index is set, i.e., the ratio of temperature to flow rate, which is calculated by dividing the first historical cleaning liquid temperature (in degrees Celsius) by the first historical cleaning liquid flow rate (in liters per minute). The obtained ratio can be used as one of the indexes reflecting the cleaning efficiency and thermal energy utilization efficiency. For example, if the temperature is high and the flow rate is small, it may indicate that the thermal energy utilization rate of the cleaning liquid is high.

[0046] Preferably, a fourth characteristic index is set, i.e., the association of the first historical cleaning operation power with corresponding time sequence information (such as cleaning start time and end time). This helps to understand the energy consumption of the cleaning equipment in different time periods, and thus provides a reference for the configuration of the thermal energy recovery system.

[0047] In a feasible implementation, the thermal energy recovery layer analyzes the thermal energy utilization and energy consumption mode of the cleaning process according to the third characteristic index (the ratio of temperature to flow rate) and the fourth characteristic index (the association of power with time sequence information). According to the thermal energy utilization of the cleaning process, a suitable thermal energy recovery technology and equipment are selected, for example, if a certain amount of thermal energy is wasted in the cleaning process, a high-efficiency heat exchanger can be selected to recover the thermal energy. According to the energy consumption mode, the working mode and parameters of the thermal energy recovery system are configured, for example, when the cleaning equipment is operating at high power, the recovery efficiency of the thermal energy recovery system can be adjusted to fully utilize the thermal energy. Considering the time sequence information, the start and stop times are reasonably arranged to ensure that the system can operate normally when thermal energy needs to be recovered.

[0048] In actual application, the configured thermal energy recovery layer is also implemented in the actual production process, and continuous monitoring and evaluation are performed. According to the monitoring results, the configuration and working parameters of the thermal energy recovery system are adjusted in a timely manner to optimize the thermal energy recovery efficiency. According to the specific parameters of the cleaning process, the thermal energy recovery layer is configured, thereby realizing the effective recovery and utilization of the thermal energy generated by the cleaning process.

[0049] Further, the second thermal energy recovery module M300 is also used to perform the following method: acquire a preset ideal cleaning quality standard, extract a first historical cleaning liquid temperature, a first historical cleaning liquid flow rate, and a first historical cleaning operation power limited cleaning process instance before the thermal energy closed loop is performed, and evaluate an initial cleaning quality; after the thermal energy closed loop is performed, evaluate a first cleaning quality and compare the first cleaning quality with the initial cleaning quality, and if the cleaning quality is degraded, connect the thermal energy recovery layer, update the thermal energy recycling rate corresponding to the cleaning process of the current vehicle component cleaning and drying cycle.

[0050] Further, the multi-stage thermal energy closed loop cooperative recovery control system is also used to perform the following method: The preset ideal cleaning quality standard includes a surface residue content less than 0.01 g / m2, a cleaning liquid temperature fluctuation range satisfying ±5°C, a preset cleaning time length, and a preset surface cleaning quality.

[0051] Based on the third characteristic index and the fourth characteristic index, configure the thermal energy recovery layer, specifically, refer to or receive a quality standard document about vehicle component cleaning, and determine the preset ideal cleaning quality standard. Exemplarily, the preset ideal cleaning quality standard generally includes: a surface residue content less than 0.01 g / m2, a cleaning liquid temperature fluctuation range satisfying ±5°C, a preset cleaning time length, and a preset surface cleaning quality (the surface of the cleaned vehicle component should be free of oil stains, impurities, and particle residues), and the pH value of the chemical residue on the surface of the cleaned vehicle component is between 6.5 and 7.5.

[0052] Preferably, before the thermal energy closed loop is performed, the first historical cleaning liquid temperature, the first historical cleaning liquid flow rate, and the first historical cleaning operation power limited cleaning process instance are extracted, and the first historical cleaning liquid temperature, the first historical cleaning liquid flow rate, the first historical cleaning operation power, and other related parameters (such as cleaning time, cleaning environment, etc.) in the cleaning process are used to evaluate the initial cleaning quality.

[0053] Preferably, evaluating the cleaning quality includes measuring the surface residue content of the cleaned vehicle component, recording the cleaning liquid temperature fluctuation during the cleaning process, and checking the surface quality after cleaning.

[0054] In a feasible implementation, before the thermal energy closed loop recovery is prepared to be performed, it is ensured that all related equipment (such as a cleaning machine and a thermal energy recovery device) is in good condition; according to the third characteristic index (the ratio of temperature to flow rate) and the fourth characteristic index (the association of power and time sequence information), the parameters of the thermal energy recovery layer, such as the thermal energy recovery efficiency and the recovery temperature, are pre-configured.

[0055] In a feasible implementation, the thermal energy closed loop recovery system is started, and the thermal energy recovery The layer starts working; when the cleaning process is carried out, real-time recording of various parameters in the cleaning process is performed, such as real-time cleaning liquid temperature, real-time cleaning liquid flow, etc.; after the cleaning is completed, the first cleaning quality is evaluated; then, the first cleaning quality is compared with the initial cleaning quality; if the first cleaning quality meets the preset ideal cleaning quality standard, it indicates that the heat energy recovery layer is effective without adjustment; if the first cleaning quality is degraded (i.e., does not meet the preset ideal cleaning quality standard), the next adjustment needs to be performed.

[0056] For example, the heat energy recovery layer is connected, and the heat energy recovery rate is updated; if the cleaning quality is degraded, the heat energy recovery layer is connected, and the configuration parameters thereof are adjusted according to the actual situation; the adjustment includes changing the heat energy recovery efficiency, adjusting the recovery temperature, changing the operation power of the heat energy recovery equipment, etc.; the heat energy recovery rate corresponding to the cleaning process of the current vehicle component cleaning and drying cycle is updated.

[0057] In the actual application process, the heat energy recovery layer configuration and the corresponding cleaning quality result are recorded; through long-term data accumulation, the operation law and optimization space of the heat energy recovery system are analyzed, and the configuration of the heat energy recovery layer is further optimized; the heat energy utilization of the cleaning process is continuously monitored to ensure the stability and optimization of the cleaning quality and the heat energy recovery efficiency, and to ensure that the heat energy recovery layer can effectively recover and utilize the heat energy generated in the cleaning process, while ensuring that the cleaning quality meets the preset ideal standard.
