A heating device with electric heating and energy storage

Abstract

The invention relates to a heating device for electric heating and energy storage, belonging to the field of energy utilization. The device includes: heat storage bricks and heat exchange tube rows, "U"-shaped steel connecting side plates on both sides of the heat exchange tube rows, filling granular heat storage materials between the heat storage bricks, heat storage bricks and heat exchange tubes The rows are connected in parallel horizontally, and electric heating elements are arranged between adjacent heat storage bricks. The combined structure of the heat storage brick and the granular heat storage material of the device of the present invention can increase the heat storage and reduce the volume of the heat storage and heat supply device. The invention makes full use of the low-cost electric energy in the valley electricity period at night through the rational use of the valley electric heating energy storage device, and realizes the purpose of energy saving and environmental protection and reducing heating costs while meeting people's heating demands in winter.

Description

technical field [0001] The invention relates to a heating device for electric heating and energy storage, belonging to the field of energy utilization. Background technique [0002] At present, the heat sources of conventional heating systems are combustion boilers, such as coal-fired boilers, oil-fired boilers, gas-fired boilers, solar water heaters, and electric heating boilers. Generally, the operating cost of coal-fired boilers is low, but the waste gas, waste, and waste water discharged from coal-fired boiler rooms will cause serious pollution to the environment. It is the cleanest energy source, but the conversion efficiency of photoelectric and photothermal energy is low at present, and it can only be used in water heaters with small heat consumption and in special environments. The application of large heat capacity is not very ideal. Pollution, but if electric heating is used day and night for heating, etc., the electricity bill is also very high. [0003] Therefo...

AI Technical Summary

Problems solved by technology

Generally, the operating cost of coal-fired boilers is low, but the exhaust gas, waste, and waste water discharged from coal-fired boiler rooms will cause serious pollution to the environment; the exhaust gas of oil-fired boilers and gas-fired boilers has less environmental pollution, but the operating costs are high; solar energy It is the cleanest energy, but at present, the efficiency of photoelectric and photothermal energy conversion is low, so it can only be used in water heaters with low heat consumption and in special environments. The application of large heat capacity is not very ideal; although general electric boilers have no emissions and Pollution, but if electricity is used for heating day and night, the electricity bill will be high
