Electric energy storage and reutilization device

Abstract

The invention provides an electric energy storage and reutilization device. The device comprises a heat preservation chamber and a controller; the heat preservation chamber is internally provided witha plurality of layers of heat storage plates, a heating pipeline and an electric heater; the heating pipeline is arranged above the heat storage plates, the two ends of the heating pipeline are in communication with an external air inlet pipeline and an air outlet pipeline correspondingly; and the controller is used for controlling the electric heater to heat the heat preservation chamber to a certain temperature at the electricity utilization valley, and during the electricity utilization peak hours, the heat in the heat preservation chamber is taken away by air flow flowing through the heating pipeline, so that heat supply is realized. According to the electric energy storage and reutilization device, electric energy can be converted into heat energy for storage when the electricity utilization cost is low at the electricity utilization valley, and the heat energy is output to achieve the heating requirement when the electricity utilization cost is high during the electricity utilization peak hours; and though using the device for heating, the electricity utilization cost can be greatly reduced, meanwhile, the reasonable distribution and utilization of electric energy are facilitated, and the device is especially suitable for industrial and commercial electricity utilization, such as being used in plants and malls.

Description

technical field [0001] The present invention mainly relates to the technical field related to energy utilization, in particular to an electric energy storage and reuse device. Background technique [0002] In some large places, such as factory buildings and shopping malls, the operation of heating equipment, especially electric heating equipment, consumes a lot of energy and costs. In some industrial and commercial electricity consumption places, in order to achieve a reasonable use of electric energy, the general electricity fee collection adopts a segmented charging method, that is, during the peak period of electricity consumption (usually during the day), the power supply is tense and the power consumption is relatively large. When the electricity price is higher, the electricity price is lower when the electricity consumption is low during the low electricity consumption period (usually at night). However, for places such as factories and shopping malls, most of the op...

Problems solved by technology

However, for places such as factories and shopping malls, most of their operating hours are during the day, and traditional electric heating equipment can only be used during the day to turn off at night. On the one hand, the cost of electricity is high and the cost is high; Allocation and utilization, resulting in waste of energy
