It should be noted that the embodiments described here are only part of the embodiments of the utility model, not all of them. Based on the following embodiments, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides the following technical solutions:

[0020] Embodiment 1:

[0021] like Figure 1 As shown, a dual-storage energy storage device for automatically adjusting water temperature distribution comprises: a dual-storage energy storage device container body 1 and a temperature regulating device, the temperature regulating device is fixedly connected to the dual-storage energy storage device container body 1, the temperature regulating device is arranged inside the dual-storage energy storage device container body 1, a plurality of water distributors 3 are arranged inside the dual-storage energy storage device container body 1, and a hot water layer 5, an inclined temperature layer 6, and a cold water layer 7 are arranged inside the dual-storage energy storage device container body 1 from top to bottom. The temperature regulating device inputs industrial cold water and hot water, i.e., the residual cold and residual heat in the industrial production process, into the dual-storage energy storage device container body 1 from the outside, monitors and regulates the situation in the dual-storage energy storage device container body 1 through the control of the temperature sensor 2 and the PLC control device, and fully stirs the dual-storage energy storage device container body 1 through the water distributor 3 to prevent a large deviation between the outer wall water temperature and the center water temperature, so that the energy efficiency of the energy storage device is kept within the normal threshold, and the energy generated by the industrial production process is effectively utilized.

[0022] The temperature regulating device includes an industrial waste heat water supply pipeline 13 and an industrial waste heat return pipeline 16 for collecting industrial waste heat, and also includes an industrial waste cooling water supply pipeline 10 and an industrial waste cooling return pipeline 12 for collecting industrial waste cooling. The industrial waste cooling water supply pipeline 10 and the industrial waste cooling return pipeline 12 are connected through a cooling pipe 11, and the industrial waste heat water supply pipeline 13 and the industrial waste heat return pipeline 16 are connected through a heating pipe 14. Electromagnetic valves 15 are installed on the industrial waste cooling water supply pipeline 10, the industrial waste cooling return pipeline 12, the industrial waste heat water supply pipeline 13 and the industrial waste heat return pipeline 16, and the on-off of each pipeline is controlled by the electromagnetic valve 15.

[0023] In industrial production, waste heat and waste cooling are common by-products, which come from various process equipment and processes. The sources of waste heat mainly include high-temperature flue gas, cooling medium, wastewater and waste gas, chemical reactions, high-humidity products and slag. These waste heat resources usually have high temperatures and large heat, and have great potential for recycling; the sources of waste cooling mainly include air conditioning condensate, etc., which usually have low temperatures and small heat, but also have certain recycling value.

[0024] The cooling pipe 11 and the heating pipe 14 are spiral in shape, and their two ends are connected to the corresponding water supply pipe and return pipe. The cooling pipe 11 and the heating pipe 14 are not in direct contact with the inner wall of the dual energy storage device container body 1. The setting of the cooling pipe 11 and the heating pipe 14 increases the contact area of ​​the waste cold and the waste heat in the dual energy storage device container body 1. By recycling the waste heat and the waste cold, the temperature and concentration of these waste gases and waste water can be reduced, the pollution to the environment can be reduced, and it is beneficial to environmental protection; by converting the waste heat into useful energy, such as electricity, hot water, etc., the energy cost can be effectively reduced and the economic benefits of the enterprise can be improved; by recycling the waste heat and the waste cold, the dependence on the cooling medium can be reduced, thereby reducing the production cost and improving the product quality; the waste heat and the waste cold generated in industrial production are a kind of reusable resource. By recycling and utilizing, the recycling of resources can be promoted and the waste of resources can be reduced.

[0025] The industrial waste heat water supply pipe 13 and the industrial waste heat return pipe 16 are fixed on the wall of the dual energy storage device container body 1, and one end of the industrial waste heat water supply pipe 13 and one end of the industrial waste heat return pipe 16 are respectively arranged at the upper and lower parts of the hot water layer 5; the industrial waste cooling water supply pipe 10 and the industrial waste cooling return pipe 12 are fixed on the wall of the dual energy storage device container body 1, and one end of the industrial waste cooling water supply pipe 10 and one end of the industrial waste cooling return pipe 12 are respectively arranged at the upper and lower parts of the cold water layer 7.

[0026] The dual-energy storage device container body 1 is arranged on an equipment base 9 , and the surface area of ​​the equipment base 9 is larger than the cross-sectional diameter of the dual-energy storage device container body 1 .

[0027] A water distributor 3 is provided at the top and bottom of the main body 1 of the dual-storage energy storage device container. The types of the water distributor 3 can be a perforated pipe, a nozzle, a filter head, a rotary water distributor, etc. The water distributor 3 evenly distributes the cold water or hot water generated in the industrial production entering the water supply pipeline to various parts of the corresponding positions of the main body 1 of the dual-storage energy storage device container to ensure the effective use and uniform distribution of water. Through the design and arrangement of the water distributor, it can be ensured that the water is evenly distributed on the packing layer of the energy storage tank, avoiding the concentration or loss of water flow, and improving the utilization rate and effect of water; the water distributor 3 has an anti-blocking design at the nozzle, which can prevent impurities and particles in the water flow from clogging the nozzle or orifice and keep the water unobstructed.

[0028] The thermocline layer 6 in the main body 1 of the dual-storage energy storage device separates the hot water layer 5 and the cold water layer 7. The thermocline layer 6 refers to a thin layer in the water body where the temperature changes rapidly with depth. The hot and cold fluids are stored in different areas, and the heat transfer and exchange is achieved through the temperature gradient of the thermocline layer 6. The thermocline layer 6 can effectively transfer heat from the hot fluid to the cold fluid, thereby improving the energy storage efficiency of the energy storage tank. In the absence of external disturbances, the thermocline layer can be maintained for a long time, thereby achieving the coexistence of hot and cold fluids in the main body 1 of the dual-storage energy storage device container. In order to maintain the stability of the thermocline layer, certain technical measures need to be taken, such as controlling the flow rate and temperature of the fluid.

[0029] Temperature sensors 2 are provided at the top and the top of the outer wall of the dual energy storage device container body 1, which respectively monitor the temperature of the water distributor 3 connected to the hot water inlet and outlet 4 and the outer wall of the top of the dual energy storage device container body 1. The hot water inlet and outlet 4 are installed on the dual energy storage device container body 1. One end of the hot water inlet and outlet 4 in the dual energy storage device container body 1 is connected to the water distributor 3 at the top. The installation position of the hot water inlet and outlet 4 is set on the opposite side of the industrial waste heat supply pipe 13 and the industrial waste heat return pipe 16.

[0030] Temperature sensors 2 are provided at the bottom and the bottom of the outer wall of the dual energy storage device container body 1, which respectively monitor the temperature of the water distributor 3 connected to the cold water inlet and outlet 8 and the outer wall of the top of the dual energy storage device container body 1. The cold water inlet and outlet 8 are installed on the dual energy storage device container body 1. One end of the cold water inlet and outlet 8 in the dual energy storage device container body 1 is connected to the water distributor 3 at the bottom. The installation position of the cold water inlet and outlet 8 is set on the opposite side of the industrial waste cooling water supply pipeline 10 and the industrial waste cooling return pipeline 12.

[0031] The temperature sensor 2 is connected to the PLC control device. By monitoring the temperature of the hot water layer 5 and the cold water layer 7, the temperature sensor 2 transmits real-time data to the PLC control device, which is used to regulate and maintain the stability of the inclined temperature layer 6; the electromagnetic valve 15 is connected to the PLC control device, and controls the flow rate of water supply and water outlet in conjunction with the monitoring results of the temperature sensor 2.

[0032] like Figure 2 As shown, the cooling pipe 11 and the heating pipe 14 are respectively fixed in the cold water layer 7 and the hot water layer 5 of the inner wall of the container body 1 of the dual energy storage device by a plurality of pipe fixings 17. The pipe fixings 17 are snap-on fixings for easy disassembly.

[0033] When in use, the PLC control device receives data from the temperature sensor 2 in real time. After the operator sets the temperature difference threshold D1 of the cold water layer 7 and the temperature difference threshold D2 of the hot water layer 5, the PLC control device controls the electromagnetic switch action according to the following logic:

[0034] (1) When the value difference between the temperature sensor 2 at the bottom outer wall of the cold water layer 7 and the bottom center of the cold water layer 7 is greater than the temperature difference threshold D1 of the cold water layer 7, the PLC control device sets the solenoid valve 15 installed on the industrial waste cooling water supply pipe 10 and the industrial waste cooling water return pipe 12 to an open state, thereby reducing the water temperature close to the outer wall through industrial waste cooling, thereby reducing the temperature difference.

[0035] (2) When the temperature of the outer wall at the bottom of the cold water layer 7 is less than or equal to the temperature at the center of the bottom of the cold water layer 7, the PLC control device sets the electromagnetic valve 15 installed on the industrial waste cooling water supply pipe 10 and the industrial waste cooling water return pipe 12 to a closed state to stop cooling. (3) When the value difference between the temperature sensor 2 at the top center of the hot water layer 5 and the outer wall at the top of the hot water layer 5 is greater than the temperature difference threshold D2 of the hot water layer 5, the PLC control device sets the electromagnetic valve 15 installed on the industrial waste heat water supply pipe 13 and the industrial waste heat water return pipe 16 to an open state, and the water temperature near the outer wall is increased by the industrial waste heat, thereby reducing the temperature difference.

[0036] (4) When the temperature of the top outer wall of the hot water layer 5 is greater than or equal to the temperature of the top center of the hot water layer 5, the PLC control device sets the electromagnetic valve 15 installed on the industrial waste heat water supply pipe 13 and the industrial waste heat return pipe 16 to a closed state to stop heating.
