Main Features

● Using steam to heat the disc. The waste water coated to the disc and evaporated quickly.  And the solid waste remaining on the disc and scraped off by a scraper;

● The water in the wastewater separated from the waste to obtain crystal-clear distilled water with COD reduced up to 99%.

● Use 316L and corrosive resistant material, such as 2205, SAF2507 or titanium, etc.

The moisture content of the final obtained dry waste ≤ 8%.


Revolutionary Advantages

● High efficiency; film evaporation method, compared with the tank evaporator, the efficiency is increased by 20%

● Capacity: disc structure, the same area, capacity can be theoretically N times unlimited extension

● Energy saving: low temperature vacuum evaporation process, evaporation temperature to 40 ℃, the lowest water effect is good

● High energy efficiency ratio: compared with the traditional evaporator, the thermal energy efficiency ratio increased by 35%.

● Processing range: high salt, high COD, high organic matter and high ammonia nitrogen wastewater can be directly to concentrate close to the solid, clear water discharged directly;

● Compact design, covers an area more than 2 times smaller than other evaporators;


Application Area

NTSALT disc film dryer is densely arranged with a hollow disc, depending on the disc, heat axis and the heat contact with the stock liquid heat exchange, the heat comes from the heat medium filled in it, the heat medium through the hollow shaft flow through the disc, the heat transfer area per unit effective volume is large, the temperature of the heat medium from -40°C to 320°C, indirect conduction heating, Such as steam, guide oil, etc., do not carry air to take away heat, heat is used to heat the material.


NTSALT dry cloth membrane distillation crystallization system USES the multiple hollow dry both sides of the disc, the disc heat transfer surface has the clean function, thin ones, with the relative movement of the disc face washing effect for water boiling, evaporation of water vapor rises to the device's dome, brought out by induced draft fan, under the condition of the above work, Using closed loop cooling loop heat pumps water and concentrate separation through the scraper scrape concentrate.



Principle Description:

The wastewater is recirculated from the storage tank through the pump into the individual feed pipes, and each feed pipe transports the liquid to the side of the heated rotating disc.

Concentrate in finished in a week after the heating disc rotation evaporation, dry solid adhesion on the heating disc, and then through the knife scrape.

The drying degree of the final product can be affected by the speed of the plate, and the resulting dry waste is discharged from the equipment through an automatic discharge system, or the liquid can be concentrated to produce a semi-solid product.
