This method is easy to operate and low in cost, but the deicing effect is poor, the noise is large, and the wind turbine needs to be shut down during the deicing process
[0006] 2. Coating method, attaching a layer of special material on the surface of the wind rotor to prevent water from adhering to the surface of the wind rotor to achieve the purpose of anti-icing. This method is simple to operate, but the coating is easily damaged, and the maintenance is difficult and costly.
However, such devices often cause a large loss of electric energy, which does not conform to the principle of "temperature matching and cascade utilization" of energy, and consumes too much high-quality energy such as electric energy.

The embodiment of the invention provides an air heat deicing device and a wind energy power system, and belongs to the technical field of mechanical engineering. According to the air heat deicing device in the embodiment of the invention, a heat pump circulation assembly communicates with an air heater through a hot air conveying pipe, refrigerant gas guided out through the heat pump circulation assembly is conveyed into the air heater, air is heated through the high-temperature refrigerant gas in the air heater, the heated hot air is conveyed into a wind wheel through the hot air conveying pipe, and heating of blades of the wind wheel is achieved. By means of the scheme, high-temperature refrigerant gas is directly used as a heat source to heat air, electric energy consumption is reduced,and the energy utilization rate is increased.
Description
technical field [0001] The present disclosure relates to the technical field of mechanical engineering, in particular to an air-heat deicing device and a wind energy power system. Background technique [0002] With the development of society, people's demand for energy is increasing. Under the existing technology, fossil energy reserves tend to be exhausted, and the environmental problems caused by fossil energy affect people's health and ecological balance. Therefore, it has become a social trend to vigorously develop clean energy and develop energy-saving technologies. As a non-polluting renewable energy, wind energy has become the research object of people, such as wind power generation and wind energy heating. Among them, the technology of using wind turbines to directly drive heat pump heating provides a new direction for clean heating in today's society. [0003] Under the operating conditions of wind turbines in winter, due to low temperature, high air humidity, sno...
