Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of antifreeze of louvers of inter-cooling towers, and relates to an antifreeze method, system, equipment and medium for the opening and closing degree of louvers of inter-cooling towers. Background Art
[0002] The northern region is rich in coal and short of water. Indirect air-cooling units (hereinafter referred to as units) have been widely used in thermal power units in northern my country due to their low dependence on water resources and good heat exchange performance. In the unit, the angle of the shutters can adjust the air flow in the system. By properly adjusting the opening and closing angle of the shutters, the speed and direction of the air flow can be controlled to avoid excessive concentration or stagnation of cold air and reduce the possibility of icing.
[0003] Since the north is prone to extreme weather such as severe cold and strong winds in winter, the unit is very likely to experience freezing and cracking of the heat dissipation tube bundle due to excessive heat dissipation. In serious cases, it will directly restrict the unit's power generation capacity, thereby affecting the safe operation of the unit and reducing the overall economic benefits.
[0004] As an important equipment in the industrial and construction fields, intercooler towers are particularly important for antifreeze in winter. However, the design and control strategies of traditional antifreeze systems are usually based on experience and rules, lacking a comprehensive understanding of complex systems. Even if measures such as fan inlet blocking are applied, the intercooler tower will still experience freezing of the heat dissipation tube bundle. The second is variable operating conditions. In actual operation, intercoolers are affected by changes in environmental conditions and changes in operating requirements. For example, changes in ambient temperature, humidity, and wind speed may cause changes in the performance of the shutter antifreeze system. In addition, the operating conditions of the intercooler tower may be constantly adjusted due to process requirements, seasonal changes, or other factors. Traditional static design and control strategies cannot adapt to this variability. Summary of the invention

[0052] Embodiment 1
[0053] refer to Figure 1 The method for preventing freezing of the shutter opening and closing degree of the intercooling tower of the present invention comprises the following steps:
[0054] 1) Obtain the shutter parameters of the indirect cooling tower;
[0055] 2) inputting the shutter parameters of the intercooling tower into the trained physical information neural network to predict the return pipe temperature distribution of the intercooling tower and the temperature distribution information in the intercooling tower;
[0056] 3) The predicted return water pipe temperature distribution of the intercooling tower and the temperature distribution information in the intercooling tower are input into the trained DDPG model to obtain the optimal opening and closing degree of the blinds in the blinds antifreeze system.
[0057] 4) Controlling the opening and closing degree of the blinds in the blinds antifreeze system according to the optimal opening and closing degree of the blinds in the blinds antifreeze system.
[0058] In this embodiment, the training process of the DDPG model is:
[0059] 31) obtaining a first historical data sample, wherein the first historical data sample includes a temperature distribution of a return pipe of an intercooling tower, a temperature distribution in a tower, and a shutter opening degree, taking the temperature distribution of the return pipe of the intercooling tower and the temperature distribution in the tower as a state space, taking the shutter opening degree as an action space, and using the first historical data sample to construct a first training set and a first test set;
[0060] 32) Establishing a DDPG model, training and testing the DDPG model using the first training set and the first test set to obtain a trained DDPG model.
[0061] It should be noted that the DDPG model is an Actor-Critic structure, in which the Actor network is responsible for learning the antifreeze optimization strategy and outputting the action of the blinds parameters; the Critic network is responsible for learning the value function and evaluating the value of the current state and action.
[0062] In this embodiment, the training process of the physical information neural network is:
[0063] 21) obtaining a second historical data sample, wherein the second historical data sample includes shutter parameters of an intercooling tower and corresponding temperature distribution of a return pipe of the intercooling tower and temperature distribution information in the intercooling tower, and constructing a second training set and a second test set based on the second historical data sample;
[0064] 22) constructing the physical information neural network, wherein the physical information neural network performs physical modeling based on the heat conduction equation, wherein the heat conduction equation is:
[0065]
[0066] Where ρ is the density of the material, c p is the specific heat capacity of the material, T is the temperature, t is the time, k is the thermal conductivity, and Q is the heat source term.
[0067] 23) Training the physical information neural network based on the training set and the test set to obtain a trained physical information neural network.
[0068] It should be noted that the present invention makes a judgment based on the predicted return pipe temperature distribution and the temperature distribution in the tower. When the return pipe temperature environment is at a low temperature, it is necessary to reduce the opening and closing degree of the shutters of the shutter antifreeze system to reduce the heat loss in the tower to provide a sufficient antifreeze effect. When the return pipe temperature environment is at a high temperature, it is necessary to increase the opening and closing degree of the shutters to prevent the return pipe temperature from being too high, resulting in a decrease in the efficiency of the system; for areas where the return pipe temperature is unevenly distributed, the opening and closing degree of the shutters in each sector is adjusted to achieve the best temperature regulation effect. When the temperature in the tower is at a low temperature, the opening and closing degree of the shutters of the shutter antifreeze system is adjusted to reduce the heat loss in the tower to provide a sufficient antifreeze effect. When the temperature in the tower is at a high temperature, it is necessary to increase the opening and closing degree of the shutters to prevent the temperature in the tower from overheating and increasing energy consumption.
[0069] The present invention is based on the physical information neural network and the DDPG model to predict the optimal opening and closing degree of the blinds in the blinds antifreeze system, and control the blinds antifreeze system to perform antifreeze protection on the intercooling tower system through the blinds antifreeze system. According to the real-time monitoring data and the changes in operating conditions, the parameters and control strategies of the blinds antifreeze system are automatically adjusted to achieve the best antifreeze effect, reduce the possibility of icing, ensure that the intercooling tower operates normally in cold weather, and avoid icing affecting its function. At the same time, it can not only reduce maintenance costs and operating costs, but also reduce energy consumption, thereby reducing energy expenses and enhancing the competitiveness of enterprises. Reducing energy consumption will also be beneficial to reducing environmental pollution and reducing carbon emissions, and have a positive impact on the sustainable development of the environment. Antifreeze protection measures are not only for protecting equipment, but also for achieving energy conservation and emission reduction and promoting the goal of sustainable development.
