Abstract

The invention discloses a liquid anti-icing and de-icing agent for a wind power blade and a preparation method of the liquid anti-icing and de-icing agent. The de-icing agent is prepared from reducing iron powder, activated carbon, diatom powder, magnesium acetate and deionized water. The reducing iron powder serves as main self-heating metal powder, the strong adsorption property of the activated carbon to gas is utilized, the self-heating heat comes from heat released by rapid reaction of the reducing iron powder and oxygen in air, the heat release amount is larger than the heat dissipation amount, the temperature is further increased, the activated carbon serves as a catalyst in the liquid anti-icing and deicing agent, and the liquid anti-icing and de-icing agent has the advantages of being rapid in starting, high in heating temperature and long in continuous heating time. The diatom powder is used as a dispersing agent in the liquid anti-icing and deicing agent, so that the contact between the iron powder and the air can be ensured, and the iron powder is not agglomerated into blocks. Magnesium acetate has a good ice melting effect, the freezing point is reduced, and the ice melting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a liquid anti-deicing agent for wind power blades and a preparation method thereof. Background technique [0002] Wind turbines are usually located in areas that are prone to freezing, such as high mountains or frontiers. Because the average annual temperature in these areas is low, it is common for outdoor temperatures to be below zero, which makes the blade surfaces of wind turbines very easy to freeze. However, at an altitude of 1000 In high-altitude areas of ~1800m and in forested areas, wind turbine blades freeze more seriously in winter. Winter is precisely the time when wind resources are relatively abundant. Once the surface of the blades freezes, it will not only have a direct impact on wind power revenue, but also pose a safety risk to share the operation of the unit. Therefore, anti-icing of wind power blades in winter is an urgent problem in...
