Description

Technical Field

[0001] The present application relates to the field of temperature control technology, and in particular to a regeneration tower temperature control method, device, equipment and storage medium. Background Art

[0002] Regeneration tower temperature control is crucial in many industrial processes, such as adsorption, separation and chemical reactions. Regeneration towers are usually used in the regeneration process of adsorbent materials such as molecular sieves and activated carbon. In these processes, temperature control has a direct impact on improving the regeneration efficiency of the adsorbent, extending its service life, and ensuring the stability of the entire process. The most common temperature control method automatically adjusts the error between the set temperature and the actual temperature to achieve stable control.

[0003] In some applications, temperature control is not just about heating, but also about cooling. Cooling is usually achieved through cooling water, air or refrigerants. A reasonable cooling system design can help prevent the equipment from overheating, especially when the regeneration tower temperature is quickly reduced to a safe value after the regeneration is completed. In traditional regeneration tower temperature control, various methods such as electric heating, steam heating or hot air heating are usually used. Although the electric heating system can provide more precise temperature control, due to its high energy consumption, especially in large-scale industrial applications, it often has problems of low energy efficiency and high operating costs. The use of steam heating system can effectively reduce energy consumption, but it requires more complex control methods. How to optimize energy use and reduce operating costs while ensuring the stability of the regeneration tower temperature is a difficult problem in current technology.

[0034] The core of the present invention is to provide a regeneration tower temperature control method, device, electronic equipment and storage medium. Through the matching between the automatic adjustment of the hot air circulation fan and the automatic adjustment of the heat exchanger steam inlet control valve, steam heating is preferentially used to increase the heating temperature and reduce the power consumption of the hot air circulation fan, thereby achieving efficient temperature control.

[0035] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] Please refer to Figure 1 , Figure 1 This is a flow chart of a first specific embodiment of a regeneration tower temperature control method provided by the present invention; the specific operation steps are as follows:

[0037] Step S101: preset the regeneration tower temperature value and obtain the regeneration tower temperature preset value;

[0038] Step S102: Obtain the regeneration tower temperature, and schedule the hot air circulation fan and the heat exchanger air inlet valve opening based on the difference between the regeneration tower temperature preset value and the regeneration tower temperature to complete the regeneration tower temperature control.

[0039] The heating temperature of the regeneration tower is increased by adjusting the steam regulation system. When the steam heating is not enough to reach the preset temperature of the regeneration tower, the hot air circulation fan is started and the temperature is maintained stable by automatically adjusting the fan speed.

[0040] When the regeneration tower temperature is lower than the regeneration tower temperature preset value, the heat exchanger air inlet valve opening is increased; when the heat exchanger air inlet valve opening reaches the maximum and the regeneration tower temperature cannot continue to rise, the hot air circulation fan speed is increased.

[0041] When the regeneration tower temperature is higher than the regeneration tower temperature preset value, reduce the hot air circulation fan wind speed; when the hot air circulation fan wind speed is reduced to the minimum output and the regeneration tower temperature cannot be further reduced, reduce the opening of the heat exchanger air inlet valve.

[0042] The temperature of the regeneration tower is continuously monitored using the temperature sensor signal, and based on the temperature change feedback, the controller automatically adjusts the opening of the hot air circulation fan and the heat exchanger air inlet valve.

[0043] In one embodiment, the priority of the hot air circulation fan and the heat exchanger is to adjust the steam input first, and when the heat exchanger adjustment cannot meet the temperature requirement, the hot air circulation fan is adjusted to supplement the temperature control.

[0044] In one embodiment, the controller is a PID controller.

[0045] This embodiment provides a regeneration tower temperature control method, which preferentially utilizes steam heating, increases the heating temperature, and reduces the power consumption of the hot air circulation fan by matching the automatic adjustment of the hot air circulation fan with the automatic adjustment of the heat exchanger steam inlet valve, thereby achieving efficient temperature control. By accurately controlling the coordinated work of steam heating and the fan, the power consumption of the hot air circulation fan can be effectively reduced, while maintaining the temperature of the regeneration tower stable, the energy utilization efficiency is improved, and the operating cost is reduced. By preferentially utilizing steam heating, the dependence on electric energy can be reduced, thereby maintaining a high heating effect while reducing energy consumption.

[0046] Based on the above embodiment, this embodiment describes a regeneration tower temperature control method, which is as follows:

[0047] Step 1: Monitor the temperature of the regeneration tower in real time through a temperature sensor;

[0048] In one embodiment, split-range control is achieved through PID automatic adjustment of the regeneration tower temperature. The basic control principle is PID control of the deviation between the actual value and the set value of the regeneration tower temperature. The controlled variable is the regeneration tower temperature. The set value of the regeneration tower temperature automatic adjustment is manually set. The upper limit of the manual set value of the regeneration tower temperature is 350°C and the lower limit is 330°C.

[0049] Step 2: According to the difference between the preset target temperature and the real-time temperature, first adjust the steam regulation system to increase the steam input and improve the heating capacity;

[0050] Step 3: If steam heating cannot meet the temperature requirement, the speed of the hot air circulation fan is automatically adjusted through the fan regulation system to assist heating;

[0051] In one embodiment, when the temperature of the regeneration tower is lower than the set value, priority is given to automatically controlling the increase in the opening of the heat exchanger steam inlet regulating valve. When the heat exchanger steam inlet regulating valve is opened to the preset maximum opening (90%) and the temperature of the regeneration tower cannot be further increased, automatic control is used to increase the output of the hot air circulation fan.

[0052] When the temperature of the regeneration tower is higher than the set value, the automatic control of the hot air circulation fan is prioritized to automatically adjust the output to reduce. When the output of the hot air circulation fan is reduced to the preset minimum output (5%) and the temperature of the regeneration tower cannot be further reduced, the automatic control reduces the opening of the heat exchanger steam inlet valve.

[0053] Step 4: Continuously monitor the temperature in real time, and automatically adjust the working status of the steam control system and the fan control system based on the temperature change feedback to maintain the target temperature.

[0054] Among them, this embodiment briefly describes the system in this method, including:

[0055] a heat exchanger for heating the air in the regeneration tower by means of steam;

[0056] Hot air circulation fan, used to accelerate the air circulation in the regeneration tower;

[0057] Steam regulation system, used to adjust the steam input and control the heating capacity of the heat exchanger;

[0058] A fan adjustment system is used to automatically adjust the speed of the hot air circulation fan according to the feedback signal of the temperature sensor;

[0059] A temperature sensor is arranged in the regeneration tower and is used to monitor the temperature of the regeneration tower in real time;

[0060] The controller is used to automatically adjust the working status of the steam regulation system and the fan regulation system according to the signal of the temperature sensor to achieve temperature control.

[0061] A regeneration tower temperature control method provided by an embodiment of the present invention achieves efficient temperature control by matching the automatic adjustment of the hot air circulation fan with the automatic adjustment of the heat exchanger steam inlet regulating valve, giving priority to steam heating, increasing the heating temperature, and reducing the power consumption of the hot air circulation fan. By accurately controlling the coordinated work of steam heating and the fan, the power consumption of the hot air circulation fan can be effectively reduced, while maintaining the temperature of the regeneration tower stable, the energy utilization efficiency is improved, and the operating cost is reduced. By giving priority to steam heating, the dependence on electric energy can be reduced, thereby maintaining a high heating effect while reducing energy consumption.
