Compared with a heater, the rotary dehumidifier has the advantages that the rotary dehumidifier has the characteristics of high dehumidification efficiency, low power consumption, simple and safe control and the like, and is more suitable for the use of the space in the wind turbine generator; but the defects are that pipelines are needed for supporting and dehumidifying, pipelines are needed for conveying dry air to each platform in an air treatment loop, and pipelines are needed for introducing fresh air and bringing out moisture in a rotating wheel in a regeneration air loop. Generally, a hose and a hard tube are adopted, the hard tube has higher requirement on mechanical checking of early design, and the hose needs to consider the problems of aging, replacement, treading and the like.
3. Condensing dehumidifier
A condensing dehumidifier is mostly adopted in an offshore wind generating set cabin, and the cabin is mostly in a sealed environment when the wind generating set runs, so that a rotary dehumidifier cannot be used. The condensing dehumidifier adopts a compressor, a condenser and an evaporator, changes water vapor in the cabin into condensed water and discharges the condensed water out of the cabin to achieve the aim of dehumidification, the overall principle is consistent with that of an air conditioner, and the mode has the advantages of mature technology and higher efficiency; however, the defects are that a drain hole is needed to drain condensed water, and water leakage and water accumulation inside the cabin are easily caused if a condensation type dehumidifier device is broken due to gas-liquid conversion.
