Background
The central heating system becomes the preferred form of the heating system in cities and towns in China, but most of the central heating systems in China still have low operation efficiency at present, and the problems of short heat source and environmental pollution also need to be further improved. Under the influence of outdoor air temperature and user behavior habit factors, the user side heat load fluctuation is obvious in the whole heating season, but the heating amount of a heat source is difficult to rapidly adjust along with the change of the load, so that the imbalance between the supply side heat load and the demand side heat load is caused. In order to solve the problem of mismatching of heat energy supply and demand, a heat storage technology is applied. The concentrated heat storage system arranged at a heat source receives more attention at present, but the unbalanced supply and demand mainly contradicts the fluctuation of heat load at a user side, and along with the enlargement of the scale of a heat supply network, although the concentrated heat storage can cut peaks and fill valleys, the concentrated heat storage is far away from the user, so that great conveying delay exists, the regulation delay effect is large, the flexibility is poor, and the timely matching of the load and the user demand is difficult to achieve. Meanwhile, in order to reduce the energy consumption and carbon emission of a heating system, wind energy is increasingly applied to the heating field as an important clean renewable resource. With the expansion of the wind power development scale in northern areas, the contradiction between the operation of wind power and a coal-fired cogeneration unit is increasingly prominent, and the problem of 'wind abandon' is caused by the forced reduction of output power and even the stop of operation of the wind power. Therefore, a clean heat supply technical scheme combining wind energy heat supply and a distributed heat storage system is provided.
The distributed heat storage system is characterized in that the heat storage tank is arranged on the side of a secondary heat supply pipeline network, can be positioned in a heat exchange station, and also can be positioned in an independent building, a structure or an underground chamber. The heat delay phenomenon can be well improved, and the arrangement of the heat storage tank can fully consider the type of the heat load covered by the heat exchange station and the position of the heat exchange station so as to better exert the heat storage effect according to local conditions. On the other hand, the distributed heat storage system is combined with wind energy, the system heat supply is realized by an electric heater by utilizing a wind power generation technology, and meanwhile, the double heat storage tanks are adopted, so that the disturbance of water is reduced in the processes of cold release and heat release, and the heat of renewable energy sources is fully utilized.
In view of the above, a distributed heat storage and clean heating system combining wind energy is designed. The system has the characteristics of rapid adjustment and strong flexibility, meets the requirements of heat supply peak regulation and low-carbon heat supply, and realizes accurate heat supply. Secondly, the distributed heat storage system can also play a role in increasing the heat supply reliability and reducing the heat loss. Meanwhile, space can be provided for the utilization of wind energy resources, the phenomenon of 'wind abandon' is reduced, the heat supply occupation ratio of renewable energy sources is improved, and economic benefits and environmental benefits are achieved.
