Solid off-peak electricity energy storage equipment

Abstract

The invention relates to solid off-peak electricity energy storage equipment. The equipment has a heat storage unit, a heat exchange unit and a control unit; the heat exchange unit and the heat storage unit are controlled by the control unit to exchange heat with a user end, wherein the heat storage unit includes a heat storage body, a heating unit set and a thermal insulation layer; the heating unit set is arranged in the heat storage body for converting off-peak electricity to heat energy and storing the heat energy in the heat storage body; the thermal insulation layer is arranged at the outer periphery of the heat storage body; the heat exchange unit includes a fan, a heat exchanger, an air flue and an air chamber, and outputs the heat energy in the heat storage body to the user end through a heat exchange mode; and the control unit includes a power cabinet, a control cabinet, a PLC and a touch screen. The equipment stores heat in the low-cost period of off-peak electricity, is a high-efficiency clean energy saving thermotechnical product in the normal-cost period at the electricity utilization peak in the day, is intelligent equipment for heating and heat supply by using an automatic control system, reduces the electricity utilization cost, is free of pollution, and is a trend in future cleaning energy development.

Description

technical field [0001] The invention relates to an electric energy storage device, in particular to a solid valley electric energy storage device. Background technique [0002] In order to control and remediate air pollution, many new achievements have been made in China in the fields of clean coal processing and development technology, clean and efficient coal combustion technology, clean coal conversion technology, and pollution emission control technology, and the transformation of coal-fired boilers has been fully implemented. The main technologies adopted include: coal to gas, coal to electricity, biomass, air source heat pump, water source heat pump, electrothermal film, etc. However, as a non-renewable resource, coal resources will eventually face the problem of resource depletion. Similarly, coal-to-gas and coal-to-biomass will encounter problems such as more restricted fuel supply. Moreover, the above technologies cannot solve the current problems of PM2.5 exceedi...
