The working principle and the beneficial effects of the technical scheme are as follows:
because the working temperature of the graphitization furnace 5 is about 3000 ℃, if natural cooling to room temperature requires a long time, the temperature in the furnace is continuously reduced after the graphitization of the product is finished by the graphitization furnace 5 through an internal circulating cooling water system, so that the purposes of quick cooling and production efficiency improvement are realized, and the internal circulating cooling water system mainly comprises an external circulating pipeline 2, a water cooling tower 1, a water pump 3 and an internal circulating pipeline 4; the water cooling tower 1 is a component for storing cooling water and providing heat exchange between the cooling water and the outside; cooling water is pumped out of the water cooling tower 1 through the external circulation pipeline 2 by the water pump 3 and enters the internal circulation pipeline 4, the internal circulation pipeline 4 is arranged in the graphitization furnace 5, and the cooling water exchanges heat with the furnace when flowing in the internal circulation pipeline 4, absorbs heat and takes heat out of the furnace; finally, cooling water is conveyed into the water cooling tower 1 through a pipeline, and the cooling water circulates in the internal circulating cooling water system to realize the rapid cooling of the graphitization furnace 5. Because the cooling tower exchanges heat with the external environment, the cooling tower is generally arranged in a factory outside a factory building; therefore, the initial temperature of the cooling water in the cooling tower is directly influenced by the outside air temperature; when the temperature of the cooling water is lower, the higher the heat absorbed by the cooling water is, the better the cooling effect is, but in practical use, the change of the temperature in summer and winter is not considered, and only when the graphitization furnace 5 needs to be cooled, the water pump 3 is switched on to convey the cooling water, so that the control causes the waste of energy; this application is through the first temperature of first temperature detection module 6 detection ring border, the influence of ambient temperature to the cooling effect has been considered in control module 7 to water pump 3's control, realized reducing water pump 3's output winter, when the initial temperature of cooling water reduces promptly, reduce the feed water volume of inner loop pipeline 4, and then reduce water pump 3's power consumption in order to reach the same cooling effect winter, realized dynamic adjustment water pump 3's output and realized reducing the energy consumption based on first temperature detection module 6. Taking the most special application example of the system as an example, namely the system only cools one graphitization furnace 5, and the system only has one water pump 3 and one internal circulation pipeline 4; the temperature detected by the first temperature detection module 6 in winter is 5 ℃; the acquired operational data includes: the temperature in the furnace is 3000 ℃, the cooling link is started, and the control module 7 controls the output power of the water pump 3 to be 22 KW; the temperature detected by the first temperature detection module 6 in summer is 30 ℃; the acquired operational data includes: the temperature in the furnace is 3000 ℃, the cooling link is started, and the control module 7 controls the output power of the water pump 3 to be 25KW at the moment.

Matching the operation state sets with each standard state set in a water pump output control library one by one to obtain a control set correspondingly associated with the standard state set matched with the operation state sets; the matching between the operation state set and the standard state set can be determined by calculating the similarity between the operation state set and the standard state set, and when the similarity between the operation state set and the standard state set is greater than a preset similarity threshold and is the maximum of all the similarities calculated in the water pump output control library; the similarity can be calculated specifically by the following formula:
wherein X represents a degree of similarity, aiThe ith data value of the running state set; biThe ith data value of the standard state set; n is the total number of data in the run state set and the total number of data in the standard state set.
And analyzing the control set to determine the control power of each water pump 3. The control set is formed by arranging the control power of each water pump 3 in sequence, namely the first data in the control set is the control power of the water pump 3 with the number of 1, and so on.

In the temperature rise stage of the graphitization furnace 5, the electric control valve is closed to prevent cooling water from flowing to take away heat in the furnace; when the graphitization furnace 5 enters the cooling stage, the electric control valve is opened to cool the graphitization furnace 5, and after the graphitization furnace is cooled to the room temperature, the electric control valve is closed. In addition, the opening of the electrically controlled valve is also a factor that affects the flow rate of the cooling water.

The working principle and the beneficial effects of the technical scheme are as follows:
when the graphitization furnace 5 is cooled, theoretically, the faster the water flow speed is, the faster the cooling speed in the furnace is; however, in practical cases, since the area of the inner circulation pipe 4 and the exchange surface in the furnace is constant, and the heat exchange takes time, there is a maximum flow rate value, i.e. above this maximum flow rate value, the cooling time is not reduced; an equilibrium point exists below the maximum flow velocity value, namely the point is the highest in energy consumption utilization, namely the ratio of the power of the water pump 3 to the heat absorption efficiency in unit time is the smallest, namely the highest in energy utilization rate; when the demand on the graphitized product is extremely low, the flow velocity corresponding to the equilibrium point with the highest energy utilization rate can be adopted as the flow velocity of the water body in the internal circulation pipeline 4; firstly, determining the demand condition of graphitized products through an image acquisition module, wherein the demand condition is mainly determined according to the quantity of products to be graphitized, the available quantity of rear ends of the products after graphitization and the time of workers; by determining the demand condition, the demand condition can be quantized into five levels, from top to bottom, the demand condition is respectively five levels, four levels, three levels, two levels and one level, and the demand condition corresponds to emergency, secondary emergency, demand, slight demand and normal; when the water is normal, setting the flow rate of the water in the internal circulation pipeline 4 as the flow rate corresponding to the equilibrium point; and in case of emergency, setting the flow velocity of the water body in the internal circulation pipeline 4 as the maximum flow velocity value.
