Research Of The Heating Technology Based On High Voltage And Power Electric Energy Conversion Solid Energy Storage

Rapid, development in recent years in our country, each enterprise brings economic benefits, at the same time, produces the corresponding environmental pollution problems, such as nitrogen oxide, sulfide, carbon dioxide and other greenhouse gases, and serious "smog" in the past two years. Coal heating method can aggravate the pollution in north china in the winter, so we need to find other forms of clean energy to replace the traditional way. In the forms of clean energy, there are three ways researching more widely, solar energy, electrical energy, ground source heat pump. Combined with the characteristics of the northern region in China, the current load pressure in the power grid, the highly coincidence between abandoning period and the heating time, the paper should research based on electric energy storage technology rather than traditional coal-fired in heating.This paper by the way of the existing heating energy analysis and comparison, it is determined to study the electrical energy storage technology is centralized electric boiler with a heat storage function;In this paper, a high voltage and high power electric heating energy storage furnace is designed, which can utilize solid heat storage mode adopted in low power and abandoned wind power. The electric energy which is idle in the night power network is converted into heat energy to be stored in the low valley electricity, wind power or solar energy power generation. And then according to different needs through the exchange device, the stored heat energy is converted into hot water, hot air and steam to be used in urban heating and industrial heat sources or power generation to the power grid during peak hours of electricity consumption. Thus high power and large power electricity storage can be achieved to solve the difficult problem of electric energy storage. And investment analysis on the electric energy storage furnace which as the representative of clean heat sources.The designed high voltage and power electric energy storage furnaces in the paper, which can direct access to lOkV and above high-voltage grid, using solid heat storage medium. It can be known that the solid heat storage has the advantages of strong heat storage capacity, small floor area, low maintenance cost, wide storage temperature range, high safety and so on. The benefit analysis of electric heating energy storage furnace and the investment analysis of heating source are carried out by using specific examples. The use of specific data to illustrate the use of electric heat storage for heating the economy and superiority. In order to provide a strong theoretical support for the large-scale popularization of high voltage and high power electric heating energy storage technology in the future.
