Three-effect evaporator principle: it is the first evaporator produced by the secondary steam again as a heating source, introduced into another evaporator, as long as the control of the pressure and solution boiling point in the evaporator, so that it is appropriately lowered, it can be used in the first evaporator produced by the secondary steam for heating. Crystallizer at this time, the first evaporator condensation is the second evaporator heating.
Three-effect evaporator can be used to deal with chemical production, food processing plants, pharmaceutical production, oil and gas collection and processing and other enterprises in the process of production of highly saline wastewater, suitable for the treatment of wastewater with a salt content of 3.5% to 25% (mass percentage), COD concentration of 2,000 to 10,000 ppm.

1) Replace the lubricating oil twice within 1 month when you start using it, and replace the lubricating oil once within 3-4 months thereafter.
2) After opening the low head, unscrew the bottom bolt of the rotor U-groove, check the scraper every four months to replace the scraper.
3) Open the bottom bearing every two months, check the bottom bearing wear, and replace the bottom bearing if necessary.
4) According to the nature of the material should be regularly soaked with warm water or solvent, cleaning the inner cylinder.
