Vertical shaft type wind turbine heat supply and storage system based on stirring heating

Abstract

The invention discloses a vertical shaft type wind turbine heat supply and storage system based on stirring heating. The vertical shaft type wind turbine heat supply and storage system is characterized in that mechanical energy of a vertical shaft wind turbine is transmitted to a stirring heater through a power transmission device, the stirring heater is driven to rotate and stir, and the mechanical energy is converted into internal energy of a stirring heating working medium; and after heat exchange between heat supply network circulating cold water and the stirring heating working medium, the temperature rises for heat supply. On the basis, a heat storage water tank is additionally arranged, so that the flexibility of the system can be effectively improved: when the heat demand of a user is relatively low, excessive hot water is stored in the heat storage water tank, and the energy loss is reduced; and when the heat demand of the user is improved, the hot water in the heat storage water tank is released while normal heat supply is performed, and the peak heat supply capacity is enhanced. Based on various vertical axis wind turbines and stirring heaters, the system has wide applicability, can be popularized and used in a large range, is high in flexibility and has both functions of heat supply and heat storage, and the energy utilization rate is further increased.

Description

technical field [0001] The invention belongs to the technical field of new energy heating, and in particular relates to a heat supply and storage system of a vertical axis wind turbine based on stirring heating. Background technique [0002] In recent years, my country has vigorously developed the wind power industry. By the end of 2020, the total installed capacity of wind power in my country has exceeded 220 million kilowatts. Correspondingly, some areas already have overcapacity of electricity, and a large number of curtailment of wind leads to serious waste of energy. At the same time, the current situation of environmental pollution in my country is severe, and it is urgent to remove smog and purify the air. Therefore, the present invention proposes a vertical-axis wind turbine heat storage system based on agitation and heating. On the one hand, it can make full use of abandoned wind resources and save renewable energy; Effectively reduce air pollution, which is condu...
