Abstract

The invention discloses a wind power blade ice-melting and ice-inhibiting agent based on exothermic reaction and a preparation method thereof. The ice-melting and ice-inhibiting agent comprises a solid component A and a liquid component B. The solid component A comprises sodium hydroxide powder and activated carbon; the liquid component B comprises acetic acid and ethylene glycol (glycerol). Sodium hydroxide and acetic acid are mainly utilized to react to generate sodium acetate and water, and a large amount of neutralization heat is released; wherein the reaction product sodium acetate has a good ice melting effect, the freezing point is reduced, the ice melting efficiency is improved, and the sodium acetate is small in erosion and corrosivity to soil and metal, easy to biodegrade, free of damage to a surface coating of the wind turbine blade and friendly to the surrounding environment.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to an ice-melting and deicing agent for wind power blades based on exothermic reaction 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...
