Thermodynamics ANSYS Analysis Of Solid Electric Storage Device

These days, air pollution is so serious that the requirement of environmental protection is increasing. At the same time, the peak and valley difference of power supply is also increasing year by year. In general people use electricity at peak period. While the low power can not be fully utilized, it brings great economic losses to the power system operation. The solid electric heat storage device is an effective method for reducing coal combustion, purifying the air and making full use of the low power energy. The application of the domestic solid electric thermal storage device starts late, there are still some technical problems compared with foreign countries. In the actual production of heating process, the heating efficiency is not high, so it is necessary to analyze the working process of the device and calculate the heat storage efficiency, and provide the basis for the structural optimization and reliability design of the solid electric heat storage device. The major contents of the thesis include the following parts:(1)First introduce the design principle, structure, working principle and key components of solid electric heat storage device.then establish the three-dimensional model of solid electrical storage device with SolidWorks.(2)According to the heat transfer of the ANSYS to the thermal storage device of the thermal storage process simulation, the temperature distribution in the re-generator is obtained.Then the experimental results show that the method is feasible to simulate the temperature distribution.(3)According to the air dynamics, the simulation of the heat release process of the solid electric heat storage device is carried out by using FLUENT, the air temperature distribution in the device and the temperature distribution in the re-generator were obtained, then the feasibility of the simulation method is compared with the results of the heat release experiment.(4)According to the simulation results of the thermal storage process of the device and the aerodynamic characteristics of the device in the process of the device, the structure of the hole is improved and the structure is improved, so as to achieve the purpose of improving the thermal efficiency of the device.The research results of this paper provide the basis for the simulation research including structure optimization design of solid electric heat storage device and reasonable operationparameters. At the same time, it has an important guiding significance for practical application of solid electrical and thermal storage device.
