Description
Technical Field
The invention relates to the technical field of cooling liquid, in particular to special cooling liquid for a water cooling system of a wind generating set, and a preparation method and application thereof.
Background
The wind power cooling liquid is a low-freezing-point liquid which can work in a wind power generation operation system all weather, can not freeze at low temperature, has good fluidity, has small evaporation at high temperature, can work continuously and take away a large amount of heat generated by wind power in the operation process, is suitable for various complex working environments, and has the advantages of long-acting corrosion resistance, scaling resistance, freezing resistance, boiling resistance, foam inhibition and the like.
Because no corresponding national standard or industry standard makes technical index requirements on cooling liquid used by a water cooling system of a wind generating set at present, the wind power cooling liquid is disordered in use and has high quality. At present, the wind power industry commonly uses motor vehicle engine cooling liquid or directly uses glycol or propylene glycol water solution with certain concentration as the cooling liquid of the water cooling system of the wind generating set. Although the working principle of the cooling liquid of the engine of the motor vehicle is similar to that of the cooling liquid of the cooling system of the wind driven generator, the operating environment has obvious difference, and the technical requirements and the detection method of partial performance indexes of the cooling liquid are different. GB 29743-2013 motor vehicle engine coolant mainly focuses on the characteristics of a motor vehicle engine circulating cooling system and specifies the technical requirements and the test method of the coolant. The operating environment of the wind generating set is a high-voltage electrified environment, so that the conductivity of the cooling liquid is strictly required, but the conductivity of the cooling liquid of the motor vehicle engine is not required, and is generally more than 2000 mu s/cm. In terms of the conductivity of the cooling liquid, the cooling liquid of the motor vehicle engine cannot be directly used as the cooling liquid of the water cooling system of the wind generating set. When the cooling system operates circularly, the ethylene glycol or the propylene glycol can be oxidized at high temperature by dissolved oxygen to generate acidic substances such as oxalic acid, formic acid and the like, and the acidic substances generated by oxidation have strong corrosivity and can cause corrosion of metal materials in the circulating cooling system. If the ethylene glycol or propylene glycol aqueous solution is directly used as the cooling liquid, the material of the water cooling system is corroded in the operation process because no metal corrosion inhibitor is added.
In the past, cooling liquid has not been regarded as important in wind turbine generator systems. However, only after several years of fan operation has the problems associated with cooling systems become a concern. Along with the increasing number of installed wind power plants, it is necessary to design a low-conductivity and corrosion-resistant cooling liquid to meet the special operating environment of the wind generating set, so as to ensure the normal operation of the wind generating set.
