Problems solved by technology

Since the salt spray filter is only equipped with louvers on the air inlet side, the ventilation and water leakage are serious. In addition, because the existing salt spray filter for offshore fans cannot automatically remove the salt spray particles attached to the filter element, the structure of the air inlet channel and the air outlet The transition is not smooth, the motor of the axial flow fan is not easy to take out and other structural defects, so there are problems such as the filter element is easy to block, the wind resistance is large, and the motor of the axial flow fan cannot be maintained.

Abstract

The invention provides a filtering device. The filtering device comprises a cabinet provided with an air inlet and an air outlet and is characterized by comprising a water baffle, a filter element, a dehumidifier and a fan unit, wherein the water baffle, the filter element, the dehumidifier and the fan unit are sequentially installed from the air inlet to the air outlet, a curving ventilation duct is formed in the water baffle, and a vibrator is installed on one side of the filter element component and enables the filter element component to vibrate. The filtering device is good in waterproof and ventilation effect and capable of effectively preventing the filter element component from being blocked.

Description

technical field [0001] The present invention relates to a filtering device, more specifically, to a salt mist filtering device used for an offshore wind power generating set. Background technique [0002] Due to the needs of the operation of the wind turbine, it is often necessary to transport the outside air to the inside of the unit to cool the unit or maintain a slight positive pressure inside the unit. However, when wind turbines are installed on the sea, coastal areas and intertidal zones, due to the high concentration of salt fog in the air, when the high salt fog air enters the unit, it will cause serious corrosion to the unit equipment. Therefore, salt mist filters are usually installed in wind turbines. The function of the salt mist filter device is to filter the salt mist particles and moisture in the air, and deliver the filtered air into the unit. [0003] Although the salt spray filter device plays a very important role in the stable operation of offshore wind...
