Electric heating energy storage heat supply device

Abstract

The invention relates to an electric heating energy storage heat supply device and belongs to the field of energy utilization. The electric heating energy storage heat supply device comprises heat storage bricks, heat exchange pipe banks, U-shaped steel connection side plates on the two sides of the heat exchange pipe banks, granular heat storage materials and electric heating elements. The spaces between the heat storage bricks are filled with the granular heat storage materials. The heat storage bricks and the heat exchange pipe banks are connected in a transverse parallel mode. The electric heating elements are arranged between adjacent heat storage bricks. The composite structure of the heat storage bricks and the granular heat storage materials of the electric heating energy storage heat supply device can increase the heat storage quantity, and the size of a heat storage heat supply device is reduced. According to the electric heating energy storage heat supply device, through reasonable usage of an off-peak electricity heating energy storage device, low-cost electric energy in the night off-peak electricity period is fully used, and the purposes of energy conservation, environment protection and reducing of the heat supply cost are achieved while the need of winter heating of people is met.

Description

technical field [0001] The invention relates to a heat supply device for electric heating and energy storage, which belongs 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 boilers. Generally, the operating cost of coal-fired boilers is low, but the waste gas, waste, and waste water discharged from the coal-fired boiler room will cause serious pollution to the environment; the waste 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, and it can only be used in water heaters with small heat consumption and in special environments. pollution, but if electric heating is used day and nigh...

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
