Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of electric energy storage technology, specifically a kind of intelligent mixed air type solid heat storage energy storage device. BACKGROUND

[0002] In rural areas of severe cold and cold regions, although coal-to-electricity, coal-to-gas and other measures are implemented, heating costs are not reduced but increased. Heat pump heating is concerned due to its high thermal efficiency and low operating cost, but its promotion in rural areas faces challenges due to high initial investment.

[0003] Under this background, intelligent mixed air type solid heat storage energy storage device emerges as the times require, which can store the heating heat required during the day during the 12-hour low valley electricity price period at night, and the maximum heat storage temperature can reach 750℃, thereby effectively reducing heating operating costs. In comparison, direct heating electric heaters not only have high energy consumption, but also cannot fully utilize night low valley electricity resources. The emergence of intelligent mixed air type solid heat storage energy storage device solves the problem of high initial investment and operating cost.

[0004] Current market solid heat storage energy storage devices are mainly divided into two categories: one is a non-forced heat release device utilizing hot air rising natural wind pressure, and the other is a device utilizing mechanical single fan forced circulation air supply to release heat. However, both of these two types of devices have obvious deficiencies. The non-forced heat release device has low heat release efficiency, small rated heat release capacity, and cannot flexibly release stored heat according to demand. The single fan forced air supply device has uncontrollable heat release outlet air temperature, excessively high heat release initial temperature (often exceeding the standard requirement of 110℃), and unstable heat release.

[0005] In addition, traditional solid heat storage energy storage devices also have defects in heat preservation. Heat storage bricks are directly in contact with heat preservation materials, resulting in poor heat preservation effect, high device surface temperature, large heat loss, and thus affecting heat storage efficiency. These problems not only reduce the energy efficiency ratio of the device, but also increase the heating cost of users.

[0006] In summary, the heat storage energy storage devices in the prior art generally have problems such as poor heat preservation effect, high device surface temperature, large heat loss, low heat storage and heat release efficiency, small rated heat release capacity, uncontrollable heat release outlet air temperature, and unstable heat release. Therefore, it is particularly important to develop a high-efficiency, stable, controllable and economically applicable solid heat storage electric heating device. INVENTION CONTENTS
