Title:

LONG-LASTING MAINTENANCE-FREE SALT SPRAY FILTERING SYSTEM AND CONTROL METHOD THEREFOR, AND SALT SPRAY ABSORPTION LIQUID CONCENTRATION SCREENING METHOD

Document Type and Number:

WIPO Patent Application WO/2021/212671

Kind Code:

A1

Abstract:

A long-lasting maintenance-free salt spray filtering system and a control method therefor. The system comprises a housing (5), a fan (4), and a controller. A primary-efficiency filtering module (1) used for filtering dust and large-particle pollutants in the air, a long-lasting chemical filtering module (2) used for filtering salt spray in the air, and a high-efficiency filtering module (3) used for filtering tiny salt spray particles residual in the previous stage are successively provided in a filtering channel of the housing (5); the long-lasting chemical filtering module (2) filters salt spray by means of a salt spray absorption liquid circulated by a water pump (24); the controller controls the water pump (24) and the fan (4) to be alternately turned on and off, so that the air containing salt spray successively passes through the primary-efficiency filtering module (1), the long-lasting chemical filtering module (2), and the high-efficiency filtering module (3) to achieve three-stage combined filtration. The filtering system is high in efficiency of filtration and absorption of salt spray, and has a long maintenance-free period.
