Description
Technical Field
The invention relates to the technical field of clean heat supply, in particular to a multi-energy complementary mobile heat supply system and method based on adsorption heat storage.
Background
The mobile heat supply is a novel heat supply mode, and the main principle is that industrial waste heat and waste heat of high-energy-consumption industries such as building materials, rubber, smelting, electric power, chemical engineering, papermaking and the like are subjected to heat energy storage through a heat storage module, then a tractor is used for conveying heat to a heat user, and the functions of transferring and supplying heat can be realized in the form of hot air, hot water or steam. The heat supply mode breaks through the traditional pipeline transportation mode and is a revolution of the heat conveying technology.
The core technology in mobile heat supply is thermal energy storage technology. The existing heat storage medium for mobile heat supply is mainly hot water, and the principle of the heat storage is that sensible heat storage is carried out through the higher specific heat capacity of water. On one hand, however, the temperature difference of hot water heat storage is small, so that the heat storage capacity is small; on the other hand, the source of the hot water is still a coal-fired boiler with high energy consumption and high pollution, which is not in line with the national situation of low carbon and emission reduction. The development of such heat storage is therefore limited. The phase change heat storage technology is a research hotspot in recent years, the principle of the phase change heat storage technology is that heat energy is stored through the heat effect in the phase change process of a substance, and the phase change heat storage technology has the advantages of high heat storage density and constant temperature in a phase change temperature range. However, in practical use, there are supercooling and phase separation (hydrated salt phase change material), low thermal conductivity (organic phase change material), and high heat loss, and thus the use has not been widespread.
In urban heat supply, because the factory is less and half is far away from a heat user, industrial waste heat is collected by a mobile heat supply vehicle and then transported to a heat utilization area, so that the heat supply cost is high, more carbon is discharged by utilizing the traditional transportation process, and the significance of mobile heat supply is lost.
