Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, and more specifically to a filtering mechanism of an evaporator for wastewater treatment. Background Art

[0002] The evaporator is equipped with a heating steam jacket on the outside of the shell and a rotatable scraper inside. The scraper is driven by the rotating shaft in the center of the cylinder. After the raw liquid is added tangentially from the upper part of the evaporator, it forms a downward rotating film along the inner wall of the shell under the drive of gravity and the rotating scraper. The finished liquid is discharged from the bottom of the evaporator, and the secondary steam is discharged from the top after passing through the demister.
