s1: firstly, introducing industrial high-salinity wastewater to be desalted into a treatment tank (1), filtering impurities through a connecting net (4) before introduction, and driving a guide rod (13) to do lifting motion through a belt wheel mechanism (8), a connecting shaft (9), a stirring rod (10), a fixed block (11) and a sleeve block (12) when a movable cylinder (7) rotates so as to enable the filtered impurities to fall on the fixed plate (3) to be uniformly cleaned;
s2: secondly, when the motor (6) drives the movable cylinder (7) to rotate, the first valve plate (15) can be driven to move back and forth in the treatment tank (1) through the transmission shaft (14), and the effect of pushing wastewater to flow in the slow flow tank (26) and the treatment tank (1) in a circulating manner through the connecting pipe (21) can be achieved, so that the water can be ensured to be in a moving state all the time, and further the evaporation efficiency is improved;
s3: then, when the first valve plate (15) and the second valve plate (29) push water to flow, the turbine (25) can be driven to rotate after generating impact force, and the cleaning brush (24) is driven to move in the connecting pipe (21) through the movable shaft (23), so that the phenomenon that salt in the waste water is remained in the connecting pipe (21) to cause blockage is prevented;
s4: finally, after the evaporation of water in the treatment tank (1), residual salt is remained in the treatment tank (1), the valves (22) on the steam outlet pipe (5) and the connecting pipe (21) are closed, the treatment tank (1) is kept in a sealed state, and the air inlet (17) and the air outlet (19) are internally provided with one-way valves, so that gas can be introduced into the connecting cavity (18) from the air inlet (17) under the movement of the first valve plate (15) and then discharged from the air outlet (19), and the first valve plate (15) blows the gas out of the discharge hole (20) through wind power while scraping the salt.
