DETAILED DESCRIPTION

[0022] The present application will be further described in detail below in conjunction with the accompanying drawings.

[0023] In an embodiment, as shown in Figures 1-5 , the present application discloses a compressed heat regeneration dryer heat energy recovery management method, specifically comprising the following steps: S10: When the high-temperature and high-humidity compressed air generated by the air compressor passes through the switching valve, an air guiding instruction is triggered to guide the high-temperature and high-humidity compressed air to the first drying tower in adsorption mode and the second drying tower in regeneration mode, respectively.

[0024] Specifically, when the air compressor produces high-temperature and high-humidity compressed air, it triggers the air guiding instruction when passing through the switch valve. This process is the starting point for the efficient operation of the entire system, and its implementation has many details. From the perspective of the air compressor, it continuously and stably produces high-temperature and high-humidity compressed air, which requires it to have good performance and stable operating state. The selection of the air compressor is crucial, and the appropriate model and specification should be determined according to the overall demand of the system, including the processing capacity of the drying tower, the scale of heat recovery, and other factors. For example, for large-scale industrial production scenarios, an air compressor with a large exhaust volume and stable pressure should be selected to ensure that sufficient high-temperature and high-humidity compressed air can be provided.

[0025] The switch valve plays a key control role in this process. The design and manufacture of the switch valve must meet the requirements of precise control, and its material needs to have good high-temperature and high-pressure resistance to adapt to the environment of high-temperature and high-humidity compressed air. At the same time, the control logic of the switch valve must be accurate and reliable, and it can timely trigger the air guiding instruction according to the operating state of the system. In order to achieve this, an advanced electronic control system is usually used to accurately control the switch valve. This electronic control system can monitor the operating parameters of the air compressor in real time, such as pressure, temperature, etc., and the working mode of the drying tower, and when it detects that high-temperature and high-humidity compressed air passes through the switch valve, it quickly issues accurate air guiding instructions.

[0026] Directing the high-temperature and high-humidity compressed air to the first drying tower in adsorption mode and the second drying tower in regeneration mode requires a reasonable layout of the pipelines. The material of the pipeline should be selected to have good heat insulation performance and pressure resistance to reduce heat loss and ensure stable air delivery. The diameter and length of the pipeline also need to be accurately calculated according to the air flow and flow rate to ensure that the air can smoothly enter the drying tower. Sealing connectors with good sealing performance should be used at the connection points of the pipeline to prevent air leakage and improve the efficiency of the system.

[0027] S20: In the regeneration process of the second drying tower, the high-temperature compressed air flowing through the first drying tower is used to preheat and desorb the drying agent in the second drying tower, generating high-temperature regeneration gas.

[0028] Specifically, in the regeneration process of the second drying tower, the high-temperature compressed air flowing through the first drying tower is used to preheat and desorb the drying agent in the second drying tower, generating high-temperature regeneration gas. First, the high-temperature compressed air from the air compressor passes through the first drying tower in adsorption mode. In the first drying tower, the drying agent plays an important role. The selection of the drying agent should be determined according to the composition and humidity of the compressed air, and common drying agents include silica gel, molecular sieve, etc. These drying agents have good adsorption performance and can effectively adsorb the moisture in the compressed air.

[0029] When the high-temperature compressed air passes through the first drying tower, the adsorption heat of the desiccant will preliminarily cool the air while adsorbing part of the moisture. This process not only reduces the temperature of the air but also reduces the humidity of the air, creating favorable conditions for subsequent drying and heat recovery. The compressed air pretreated by the first drying tower still has certain temperature and energy, which is guided to the second drying tower in the regeneration mode. In the second drying tower, these residual heat is fully utilized to heat and desorb the desiccant in the second drying tower.

[0030] The desiccant in the second drying tower will reach a saturated state after a period of adsorption and needs to be regenerated. Through the heating of high-temperature compressed air, the moisture in the desiccant is evaporated to form high-temperature regeneration gas. In order to ensure the efficient performance of the preheating desorption process, the structural design of the second drying tower should be reasonable. The desiccant filling method in the tower should be uniform to ensure that the air can fully contact with the desiccant and improve the desorption efficiency. At the same time, the airflow distribution in the tower should be uniform to avoid local overheating or overcooling. The airflow distribution can be optimized by setting guide plates and other devices to make the high-temperature compressed air flow evenly through the desiccant, achieving better preheating desorption effect.

[0031] S30: Introduce the high-temperature regeneration gas into a regeneration cooler to exchange heat with the cooling medium, so that it is cooled and condensed to separate out liquid water.

[0032] Specifically, the high-temperature regeneration gas is introduced into a regeneration cooler to exchange heat with the cooling medium, so that it is cooled and condensed to separate out liquid water. The regeneration cooler is one of the core components of the entire heat recovery system, and its design and performance directly affect the efficiency of heat recovery. There are many types of regeneration coolers, such as plate heat exchangers, tube heat exchangers, etc. When selecting a regeneration cooler, the appropriate type should be determined according to the specific needs and working conditions of the system.

[0033] In the regeneration cooler, the high-temperature regeneration gas and the cooling water exchange heat in counterflow. The counterflow heat exchange method can improve the efficiency of heat exchange, so that the regeneration gas can more fully transfer heat to the cooling water. In order to ensure the effect of heat exchange, the internal structure of the regeneration cooler should be designed reasonably, such as increasing the heat exchange area, optimizing the water flow channel, etc. Through these measures, the temperature of the regeneration gas can be rapidly reduced to below the dew point temperature, and the water vapor in it can be condensed into liquid water.

[0034] In the heat exchange process, the flow rate and temperature of the cooling water are also critical factors. The flow rate of the cooling water needs to be accurately adjusted according to the flow rate and temperature of the regenerated gas to ensure that the heat in the regenerated gas can be timely removed. At the same time, the temperature of the cooling water needs to be maintained within a suitable range, as too low a temperature may cause excessive condensation of moisture in the regenerated gas, affecting the normal operation of the system, and too high a temperature may reduce the efficiency of heat exchange. The flow rate and temperature of the cooling water can be monitored and adjusted in real time through the use of devices such as temperature sensors and flow regulating valves, ensuring the stable operation of the heat exchange process.

[0035] The condensed water produced after heat exchange needs to be separated from the system and discharged. The gas-water separator is an important device for achieving this function. The working principle of the gas-water separator is to separate the condensed water from the regenerated gas using gravity, centrifugal force, and other actions. Its structure needs to be designed reasonably to effectively separate the condensed water while avoiding the leakage of regenerated gas. The separated condensed water can be discharged from the system through a drainage pipeline, and in order to prevent the drainage pipeline from being blocked, the drainage pipeline needs to be cleaned and maintained regularly.

[0036] S40: The cooling medium after recovering heat is delivered to the heat utilization unit, realizing the reuse of heat energy, and real-time coordination of the operating parameters of the air compressor and the drying tower to maintain system pressure balance.

[0037] Specifically, the cooling medium after recovering heat is delivered to the heat utilization unit, realizing the reuse of heat energy. The cooling medium is usually water, which has a higher temperature after absorbing waste heat and becomes a heat recovery medium carrying waste heat. The heat utilization unit can be a process heating device, a heating system, etc., and has different requirements for the temperature and flow rate of the heat recovery medium according to different heat utilization needs. In order to ensure that the heat recovery medium can meet the needs of the heat utilization unit, accurate control needs to be carried out during delivery.

[0038] Temperature sensors and flow regulating valves, etc. are arranged on the delivery pipeline to monitor the temperature and flow rate of the heat recovery medium in real time, and adjust them according to the feedback information of the heat utilization unit. If the heat utilization unit needs a higher temperature heat recovery medium, the flow rate or temperature of the heat recovery medium can be increased to meet the needs; if the needs of the heat utilization unit are lower, the flow rate or temperature can be appropriately reduced. In this way, the efficient use of heat energy can be realized, and the energy utilization rate of the system can be improved.

[0039] At the same time, the operating parameters of the air compressor and the drying tower need to be coordinated in real time to maintain system pressure balance. The control system plays a core role in this process. The control system needs to monitor the pressure at key points in the drying machine system in real time, including the inlet pressure of the first and second drying towers and the back pressure of the regenerated gas path. Through devices such as pressure sensors, pressure data is transmitted to the control system in real time.

[0040] Based on the monitored pressure data, the control system dynamically adjusts the opening degree of the switching valve or the exhaust capacity of the air compressor. If the system pressure is too high, the control system will appropriately reduce the opening degree of the switching valve, reduce the flow of air, or reduce the exhaust capacity of the air compressor to reduce the system pressure; if the system pressure is too low, the control system will increase the opening degree of the switching valve, increase the flow of air, or increase the exhaust capacity of the air compressor to increase the system pressure. Through this dynamic adjustment, the system resistance change caused by the mode switching of the first drying tower and the second drying tower can be effectively compensated, ensuring the balance and stable operation of the entire system, and avoiding negative impact on the performance of the air compressor and the dryer.

[0041] In summary, the compressed heat regeneration dryer heat energy recovery management method realizes efficient heat energy recovery and stable system operation through precise steps and reasonable control, making an important contribution to energy saving and environmental protection in industrial production.

[0042] In an embodiment, in step S20, during the regeneration process of the second drying tower, the high-temperature compressed air flowing through the first drying tower is used to preheat and desorb the desiccant in the second drying tower, generating high-temperature regeneration gas, which specifically includes: S21: Make the high-temperature compressed air from the air compressor first pass through the first drying tower in adsorption mode, use the adsorption heat of the desiccant in the first drying tower to preliminarily cool the air and adsorb part of the moisture.

[0043] First, the high-temperature compressed air from the air compressor enters the first drying tower in adsorption mode. The high-temperature compressed air produced by the air compressor has high temperature and humidity, with a temperature usually above 120°C, carrying a large amount of heat energy and water. When this high-temperature compressed air enters the first drying tower, the first drying tower is filled with desiccant, which has strong adsorption capacity.

[0044] From a microscopic perspective, the surface and interior of the desiccant have a large number of microporous structures, and these micropores have a large specific surface area. When high-temperature compressed air flows through the desiccant, water molecules in the air will undergo physical adsorption with active sites on the surface of the desiccant. Physical adsorption is based on intermolecular van der Waals forces, and water molecules will be adsorbed firmly on the surface of the desiccant micropores, thereby achieving adsorption of water in the compressed air. At the same time, adsorption heat is released during the adsorption process. This is because the water molecules change from a gaseous state to being adsorbed on the surface of a solid, and the intermolecular potential energy decreases. According to the law of conservation of energy, this part of the reduced potential energy is released in the form of heat energy.

[0045] From a macroscopic perspective, this adsorption heat will have an impact on the high-temperature compressed air entering the first drying tower. On the one hand, the release of adsorption heat causes the temperature of compressed air to further rise, but due to the presence of the desiccant, its absorption and buffering of heat will gradually lower the temperature of the compressed air. This preliminary cooling process is a complex heat exchange process involving heat conduction, heat convection, and other heat transfer methods between air and desiccant. In the process of heat conduction, air molecules collide with the molecules on the surface of the desiccant, and heat is transferred from the air to the desiccant; in the process of heat convection, air flows in the first drying tower, forming a heat flow and accelerating the transfer of heat.

[0046] S22: Directing the compressed air pretreated by the first drying tower to the second drying tower in the regeneration mode to heat and desorb the second drying tower desiccant using the residual heat.

[0047] Specifically, after being pretreated by the first drying tower, the temperature of the compressed air is lowered, and the moisture content is also greatly reduced. At this time, this pretreated compressed air is directed to the second drying tower in the regeneration mode. The desiccant in the second drying tower has adsorbed a large amount of moisture and is in a saturated state due to being in the adsorption mode before. When the pretreated compressed air enters the second drying tower, the residual heat it carries plays a key role.

[0048] From the perspective of heat transfer, the heat in the compressed air is transferred to the desiccant in the second drying tower through heat conduction and heat convection. Heat conduction gradually raises the temperature inside the desiccant, while heat convection accelerates the diffusion of heat inside the desiccant. As the temperature rises, the thermal motion of water molecules adsorbed in the desiccant intensifies, and when the temperature rises to a certain extent, the water molecules gain enough energy to overcome the adsorption force on the surface of the desiccant, desorbing from the surface of the desiccant and realizing the desorption process.

[0049] From the perspective of chemical kinetics, the desorption process is a dynamic equilibrium process. Under high-temperature conditions, the desorption reaction rate increases, causing water molecules to continuously desorb from the surface of the desiccant, forming high-temperature regeneration gas. This regeneration gas carries a large amount of heat energy and water vapor, providing a rich energy source for the subsequent heat recovery step.

[0050] The design and control of the system also play an important role throughout the process. Precise control of the switching valve ensures that compressed air can accurately enter the corresponding drying tower according to the flow. At the same time, the control system monitors the pressure, temperature and other parameters of the first and second drying towers in real time, and dynamically adjusts the opening of the switching valve and the running state of the air compressor according to these parameters. For example, when the pressure in the first drying tower is too high, the control system will appropriately increase the opening of the switching valve to ensure that the compressed air can pass smoothly; when the temperature in the second drying tower is too low, the control system will adjust the running state of the air compressor to increase the temperature and flow of the compressed air to ensure that the drying agent can be fully regenerated.

[0051] In addition, this design also considers the stability and energy saving of the system. By first passing the compressed air through the first drying tower for preliminary cooling and water adsorption, and then using the remaining heat to regenerate the drying agent in the second drying tower, the problem of high temperature and high energy consumption that may be caused by directly using high-temperature compressed air to regenerate the second drying tower is avoided. At the same time, this orderly heat transfer and utilization method significantly improves the energy utilization efficiency of the entire system, realizes efficient recovery of heat energy and effective regeneration of drying agent, and provides strong protection for the stable operation and heat energy recovery of the compressed heat regeneration dryer.

[0052] In an embodiment, in step S30, the high-temperature regeneration gas is introduced into a regeneration cooler to exchange heat with the cooling medium, so that it is cooled, condensed and separated from liquid water, specifically including: S31: In the regeneration cooler, the high-temperature regeneration gas is exchanged with the cooling water in counterflow to cool the regeneration gas to below the dew point temperature and condense the water vapor therein.

[0053] Specifically, real-time monitoring of the pressure at key points in the dryer system is the basis of the entire process. The pressure monitoring of the key points mainly includes the inlet pressure of the first and second drying towers and the back pressure of the regeneration gas path. In order to realize accurate monitoring of these pressures, high-precision pressure sensors will be installed in the system. At the inlet of the first and second drying towers, the pressure sensors will be accurately installed at the appropriate position to ensure that the pressure of the compressed air entering the drying tower can be captured in real time. These pressure sensors will transmit the monitored pressure data to the control system in the form of electrical signals.

[0054] For the back pressure monitoring of the regeneration gas path, a dedicated pressure sensor will also be installed. The back pressure of the regeneration gas path is crucial for the stability of the entire system, as changes in back pressure will directly affect the flow of regeneration gas and the effectiveness of heat exchange. The pressure sensor will continuously monitor the back pressure of the regeneration gas path and feed real-time data to the control system. The control system will analyze and process these pressure data in real time, establishing a dynamic model of pressure changes. By analyzing and comparing historical data, it can predict the trend of pressure changes and make adjustments accordingly in advance.

[0055] S32: The condensed water generated after heat exchange is separated from the system and discharged, while the cooling water with increased temperature is output as a heat recovery medium carrying waste heat.

[0056] Specifically, based on the monitored pressure data, the control system will compensate for the change in system resistance caused by the mode switching of the first and second drying towers by dynamically adjusting the opening of the switching valve or the exhaust volume of the air compressor. When the first and second drying towers switch modes, the resistance of the system will change significantly. For example, when switching from adsorption mode to regeneration mode, the path and flow of gas will change, causing the system resistance to increase.

[0057] In this case, the control system will make appropriate decisions based on the monitored pressure data. If the pressure data shows that the system resistance has increased, causing fluctuations in the inlet and outlet pressures of the dryer, the control system will first consider adjusting the opening of the switching valve. The adjustment of the opening of the switching valve is a delicate process, and the control system will accurately calculate the size of the opening that needs to be adjusted based on the amplitude and trend of the pressure change. By gradually adjusting the opening of the switching valve, the path and flow of compressed air and regeneration gas can be changed, thereby balancing the pressure of the system.

[0058] If adjusting the opening of the switching valve cannot effectively compensate for the change in system resistance, the control system will further adjust the exhaust volume of the air compressor. The adjustment of the exhaust volume of the air compressor is a relatively complex process that needs to consider multiple factors. The control system will accurately calculate the size of the exhaust volume that needs to be adjusted based on the pressure data and the operating state of the system. By adjusting the intake valve of the air compressor or the speed of the motor, the exhaust volume can be accurately controlled.

[0059] During the adjustment process, the control system will monitor the pressure changes of the system in real time to ensure that the effect of the adjustment meets the expectations. If the adjustment is excessive or insufficient, the control system will make timely corrections to ensure the stability of the system pressure. At the same time, the control system will also consider the overall energy consumption of the system, striving to reduce energy consumption while ensuring the stable operation of the system.

[0060] In addition to real-time monitoring and dynamic adjustment of pressure, the control system also monitors and controls other key parameters such as temperature and flow rate. The coordinated control of these parameters can further improve the stability and efficiency of the system. For example, in the heat recovery process, the control system adjusts the flow rate of the cooling medium according to the temperature data to ensure the effectiveness of heat exchange and the temperature rise of the cooling medium to the appropriate range.

[0061] By monitoring the pressure at key points in the dryer system in real time and dynamically adjusting the opening of the switching valve or the exhaust capacity of the air compressor based on the monitoring data, the system resistance changes caused by the mode switching of the first and second drying towers can be effectively compensated, ensuring the pressure balance and stable operation of the system. At the same time, this precise control strategy can also improve the heat recovery efficiency of the system and reduce the overall energy consumption, achieving the goal of energy saving and emission reduction. In practical applications, this advanced control technology can provide reliable protection for the heat recovery management of the compressed heat regeneration dryer and promote the sustainable development of the industry.

[0062] In an embodiment, in step S40, the cooled medium after recovering heat is delivered to the heat utilization unit, realizing heat energy reuse, and real-time coordination of the operating parameters of the air compressor and the drying tower to maintain system pressure balance, specifically including: S41: Real-time monitoring of the pressure at key points in the dryer system, including the inlet pressure of the first and second drying towers and the back pressure of the regeneration gas path.

[0063] Specifically, for the inlet pressure monitoring of the first and second drying towers, pressure sensors are installed at appropriate positions of the drying tower inlet pipeline. This allows timely capture of changes in compressed air pressure entering the drying tower. During the operation of the dryer, the inlet pressure is affected by various factors, such as the exhaust capacity of the air compressor and the opening of the switching valve. When the exhaust capacity of the air compressor changes, the inlet pressure of the drying tower will rise or fall accordingly. By monitoring the inlet pressure in real time, the control system can timely understand the working state of the drying tower and determine whether there is an abnormal pressure condition.

[0064] The back pressure monitoring of the regeneration gas path is also crucial. The regeneration gas path is the channel for the flow of regeneration gas during the regeneration process, and the back pressure directly affects the regeneration effect and the stability of the system. By installing pressure sensors in the regeneration gas path, the change in back pressure can be monitored in real time. An abnormally high back pressure may indicate that the regeneration gas path is blocked or the resistance has increased, which will affect the normal flow of regeneration gas and thus affect the regeneration effect of the drying agent. On the other hand, a too low back pressure may result in the regeneration gas being unable to effectively preheat and desorb the drying agent.

[0065] S42: Based on the monitored pressure data, the control system dynamically adjusts the opening degree of the switching valve or the exhaust capacity of the air compressor to compensate for the change in system resistance caused by the mode switching of the first and second drying towers.

[0066] Specifically, based on the monitored pressure data, the control system conducts in-depth analysis and processing. The control system compares the real-time acquired pressure data with the preset pressure range. The preset pressure range is determined according to the design parameters of the dryer and the actual operation experience, which can ensure the optimal operation of the dryer. If the monitored pressure data exceeds the preset range, the control system will immediately issue an alarm and start the corresponding adjustment mechanism.

[0067] Dynamic adjustment of the opening degree of the switching valve is one of the important means of adjustment by the control system according to the pressure data. The switching valve plays a key role in controlling the flow path of compressed air and regeneration gas in the entire system. When abnormal pressure is detected at key points in the dryer system, the control system will adjust the opening degree of the switching valve according to the specific situation. For example, if the first drying tower inlet pressure is too high, the control system will appropriately reduce the opening degree of the switching valve to reduce the amount of compressed air entering the first drying tower, thereby reducing the inlet pressure. Conversely, if the inlet pressure is too low, the control system will increase the opening degree of the switching valve to increase the supply of compressed air.

[0068] Adjusting the exhaust capacity of the air compressor is also an important measure to maintain the balance of system pressure. The exhaust capacity of the air compressor directly affects the pressure distribution in the dryer system. When the pressure data shows that the system pressure is insufficient, the control system will adjust the operating parameters of the air compressor to increase its exhaust capacity to increase the system pressure. Conversely, when the system pressure is too high, the control system will reduce the exhaust capacity of the air compressor to avoid damage caused by excessive pressure.

[0069] During the adjustment process, the control system will use advanced algorithms and control strategies to ensure the accuracy and timeliness of the adjustment. For example, using a PID control algorithm, the opening degree of the switching valve and the exhaust capacity of the air compressor are dynamically adjusted according to factors such as the size of the pressure deviation and the rate of change. This can quickly stabilize the system pressure within the preset range and avoid excessive pressure fluctuations that affect the normal operation of the dryer.

[0070] By monitoring the pressure at key points within the dryer system in real time and dynamically adjusting the opening of the switching valve and the exhaust capacity of the air compressor based on the monitoring data, the system resistance changes caused by the mode switching of the first drying tower and the second drying tower can be effectively compensated. During the mode switching process of the drying tower, the airflow path of the system changes, resulting in changes in system resistance. This resistance change may cause pressure fluctuations, affecting the normal operation of the dryer. Through the above adjustment measures, the system operating parameters can be adjusted in a timely manner to keep the system pressure balanced, ensuring smooth operation of the dryer during mode switching and improving the working efficiency and stability of the dryer. At the same time, it realizes efficient recovery and utilization of heat energy, reduces the comprehensive energy consumption of the system, and brings significant economic and environmental benefits to the enterprise.

[0071] In an embodiment, after step S40, the compressed heat regeneration dryer heat energy recovery management method further comprises: S50 After a preset period of time, control the switching valve to switch states, so that the roles of the first drying tower and the second drying tower are exchanged, i.e. the first drying tower is converted from adsorption mode to regeneration mode, and the second drying tower is converted from regeneration mode to adsorption mode.

[0072] During the switching process, the following sub-steps are performed: S51: At the beginning of the switching process, perform pressure equalization operation to balance the pressure of the first drying tower and the second drying tower, and prevent airflow impact.

[0073] S52: After the pressure equalization is completed, completely switch the airflow path to realize smooth alternation of the first drying tower and the second drying tower.

[0074] Specifically, when the preset period arrives, the control system will issue a switching instruction to control the switching valve. The setting of the preset period is based on the comprehensive consideration of the working efficiency of the dryer, the adsorption and regeneration capacity of the drying agent, and other factors. The control system accurately records the time, and when the time reaches the preset value, the switching instruction is triggered. The switching valve is the key component in the entire mode switching process, and its state switching determines the path of compressed air and regeneration gas flow. The control of the switching valve adopts advanced electronic control technology, which can realize precise action. The control system sends an electrical signal to the switching valve according to the preset program, and the switching valve changes the position of the valve core through the internal electric actuator after receiving the signal, thereby realizing the switching of the airflow path. This switching method has the advantages of fast response speed and high control precision.

[0075] During the switching process, first of all, the equalization operation will be carried out. The equalization operation is an important step to ensure the smooth switching of the drying tower, and its purpose is to make the pressure of the first drying tower and the second drying tower tend to be balanced, preventing the impact of gas flow from causing damage to the system. When the equalization operation starts, the control system will open the equalization valve to form a communication channel between the two drying towers. The opening of the equalization valve is realized through a precise control algorithm, and the control system will adjust the opening of the equalization valve according to the real-time pressure difference between the two drying towers to ensure that the pressure difference decreases smoothly. During the equalization process, the pressure changes of the two drying towers will be monitored in real time. The pressure sensor will feed back the detected pressure data to the control system, which will analyze and process these data. If the pressure difference decreases too fast or too slow, the control system will adjust the opening of the equalization valve in time to ensure the stability of the equalization process. At the same time, in order to improve the efficiency of equalization, auxiliary equalization devices such as equalization fans can also be used. The equalization fan can accelerate the gas flow between the two drying towers, making the pressure tend to balance faster. The operating parameters of the equalization fan will also be adjusted in real time according to the pressure difference to ensure the equalization effect.

[0076] After the equalization is completed, the gas flow path is completely switched. In the judgment of equalization completion, the control system will determine according to the preset pressure difference threshold. When the pressure difference between the two drying towers is less than this threshold, the control system will consider that the equalization is completed and will issue a signal to completely switch the gas flow path. The complete switching of the gas flow path is realized through the further action of the switching valve. After the equalization is completed, the switching valve will continue to change the position of the valve core to make the compressed air and the regeneration gas flow according to the new path. At this time, the first drying tower is converted from the adsorption mode to the regeneration mode, and the second drying tower is converted from the regeneration mode to the adsorption mode. In order to ensure the accuracy and stability of the switching of the gas flow path, multiple protection mechanisms will be used during the switching process. For example, before the switching valve acts, it will be self-checked to ensure its normal work. At the same time, gas flow monitoring devices will be installed to monitor the flow and direction of the gas flow in real time. If the gas flow is found to be abnormal, measures will be taken to adjust in time, such as re-adjusting the position of the switching valve or suspending the switching process.

[0077] Through this precise mode switching and equalization operation, the smooth alternation of the work of the first drying tower and the second drying tower can be realized. The smooth alternation can avoid damage to the drying agent caused by pressure fluctuations and gas flow impact, prolong the service life of the drying agent. At the same time, it can ensure the stability of the drying effect of the dryer, provide stable heat energy supply for the subsequent heat using unit, improve the operation efficiency and reliability of the whole compressed heat regeneration dryer heat energy recovery management system, reduce the maintenance cost and energy consumption of the system, and achieve the goal of energy saving and emission reduction.
