Description
Technical Field
The utility model relates to an intermittent type exhaust formula high temperature heat accumulation system.
Background
With the rapid development of industry, China faces huge environmental protection pressure, especially haze pollution. In order to effectively treat haze pollution and improve air quality, a plurality of provinces and cities greatly promote a coal-to-electricity project, namely, an electric heating mode is adopted to replace the heating mode of a traditional coal-fired boiler. Meanwhile, aiming at the condition that the difference between the daytime peak valley and the nighttime peak valley of the power supply in China is large, the government issues a night valley power utilization preferential policy and encourages the low-cost valley electric heating heat storage material to store heat energy, thereby achieving the aim of 'peak clipping and valley filling'.
At present, the central heating type and the direct heat radiation type are generally adopted for heating in China. The direct heat radiation type is to heat the fused salt (the fused salt can be heated to 300-400 ℃ and has high heat storage density) by using electric power to store heat, and the heat is directly radiated or convected through air. The fused salt heat storage type central heating system adopts a fused salt furnace, and the powdered fused salt is heated to the melting point of more than 142 ℃ by using electric power, so that the fused salt transfers heat to heating water or air through a heat exchanger in a fused flowing state.
However, the existing molten salt heat storage type central heating system has the following defects:
⑴ because the heat storage temperature of the fused salt is too high, if the fused salt directly exchanges heat with water, the steam pressure is too high, which easily causes danger, therefore, the high temperature resistant heat transfer medium (such as heat conducting oil) needs to exchange heat to water through the coupling heat exchanger for many times, thus, the heating system is large in size, complex in structure and high in construction cost.
⑵ the maximum working temperature of some molten salts can reach 800 ℃ (such as sodium sulfate), and due to the structural limitation of the whole heating system, the heat storage temperature of the molten salt cannot be too high in practical use, so that the heat storage temperature of the molten salt is limited, and the heat storage density is small.
