Description

Technical Field

[0001] The present invention relates to the technical field of industrial energy conservation, and is particularly suitable for dynamic energy storage systems in continuous production enterprises such as tire factories. Background Art

[0002] The tire manufacturing industry currently faces a significant energy bottleneck. Under the traditional production model, significant amounts of waste heat generated in high-temperature workshops like mixing and vulcanization are not effectively recovered, resulting in a generally lower than 50% overall plant-wide energy efficiency and a unit energy consumption of 0.5-0.7 tons of standard coal per tire. Furthermore, the company's heavy reliance on coal-fired steam boilers to meet process requirements has resulted in high carbon emissions, averaging 1.2-1.8 kg of CO2 per tire, far exceeding global carbon neutrality targets. This decentralized energy supply model also leads to duplicated equipment investment. The independently configured electric refrigeration system in the molding workshop consumes over 25% of the plant's total energy consumption, creating a significant conflict between heating and cooling and the heating needs of other workshops.

[0003] Existing technologies attempt to improve energy efficiency through waste heat recovery, but they suffer from fundamental flaws. For example, energy storage devices are insufficiently capacitive and lack multi-energy integration capabilities, making them unable to cope with workshop load fluctuations. Solar thermal and photovoltaic systems generally operate independently, with a combined conversion efficiency of less than 60%, failing to fully tap the potential of clean energy. More critically, existing solutions lack a precise workshop-level energy supply strategy. The energy waste rate of oil tank insulation in the mixing workshop exceeds 40%, and the mismatch between the cooling rollers and production speed in the extrusion workshop results in an energy efficiency loss of more than 25%. These technical bottlenecks have constrained the tire industry's green transformation process, and there is an urgent need to develop a plant-wide dynamic energy storage system to achieve intelligent regulation of energy flow and optimized cross-workshop configuration. Summary of the Invention

[0004] The present invention aims to build a dynamic energy storage system covering the entire factory. By integrating multiple energy sources such as solar energy, industrial waste heat and off-peak electricity, it can achieve efficient energy circulation and intelligent control of the entire tire production process. The system uses a solar thermal-photovoltaic-wind integrated device as the external energy input terminal, combined with a waste heat recovery network and a multi-energy complementary energy storage unit, to break through the limitations of independent energy supply in traditional workshops and establish cross-regional energy sharing and scheduling. It can achieve the coordinated optimization of deep utilization of waste heat in the mixing workshop, extrusion workshop, molding workshop, and vulcanization workshop and direct steam supply to the vulcanization workshop. Through intelligent microgrids and fuzzy control algorithms, energy distribution and dynamic balance on demand can be achieved, ultimately forming a green manufacturing energy solution.

[0068] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0069] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements that are inherent to such process, method, article or terminal device. In the absence of further restrictions, elements defined by the phrase "include..." or "includes..." do not exclude the presence of additional elements in the process, method, article or terminal device that includes the elements. In addition, in this article, "greater than", "less than", "exceed" and the like are understood to exclude the number itself; "above", "below", "within" and the like are understood to include

[0070] Original number.

[0071] Taking the above example as an example, the method is as follows:

[0072] A tire factory with an annual output of 3 million tires has applied the dynamic energy storage system of the present invention to achieve intelligent control of energy flow throughout the factory and optimized configuration across workshops. The system configuration includes a 20,000 m2 solar thermal-photovoltaic integrated device (photothermal conversion efficiency 78%, photovoltaic panel efficiency 22%), 12 waste heat recovery heat pumps (each with a heating capacity of 150kW and a COP of 4.8), 8 steam energy storage tanks (each with a capacity of 1000kWh) and 500m 3 Phase change energy storage device (energy storage density 200kWh / m 3 ). The photovoltaic panels on the upper layer of the solar thermal-photovoltaic device generate electricity to meet 78% of the electricity demand of the heat pump, and the vacuum tube collectors on the lower layer generate an average of 1200GJ of heat per day (equivalent to saving 140 tons of standard coal). The waste heat recovery network covers workshops such as mixing, extrusion, molding, and vulcanization. Through heat exchange technology, waste heat is converted into 50-70°C hot water and incorporated into the energy storage system. The phase change energy storage device stores low-valley electric heat at night and releases energy during the day to ensure that the water temperature of the entire energy storage system is constant during peak periods. At the same time, the lithium battery storage device releases the electric energy stored in the valley electricity to heat the water. It is finally stored in the hot water storage tank. In the process of gathering within the system, it meets the hot water needs for bathing in various workshops and the hot water needs of processes, such as mixing and drying rooms for glue, mixing and pre-mixing isolation agent hot water, extrusion nail rooms, etc. The hot water continues to be heated by a water source heat pump or a steam heat pump to convert the hot water into steam and store it in a steam storage tank. The total capacity of the steam energy storage tank is 8MWh, which can provide 150℃ superheated steam (pressure 1.0MPa) directly to the vulcanizing machine. The water lost in the system is replenished through the municipal pipeline network or well water. In addition, the entire energy storage system can also partially supply the energy needs outside its system, such as supplying the insulation of the oil tanks and pipelines in the entire plant. The entire system is adjusted through the master control, and the data of each node can be called at any time, and the optimal solution is generated through AI processing for overall coordination. The overall energy efficiency of the system is increased to 82%, the energy consumption per unit product is reduced from 0.6 tons of standard coal / bar to 0.28 tons of standard coal / bar, and the annual CO2 emissions are reduced by 75.9% to 1,400 tons. The molding workshop is cooled by a centralized cooling system (total air volume 120,000 m 3 / h) maintains a constant temperature of 22-26°C. Spiral coil heat exchangers (90% heat exchange efficiency) are used to insulate oil tanks in the mixing workshop, reducing energy consumption by 60%. The closed-loop cooling system for the cooling rolls in the extrusion workshop has an 85% air recovery rate, increasing cooling efficiency by 30%. This system saves 12 million yuan in energy costs annually, with a payback period of just 2.5 years.
