A large amount of feed liquid is intake by the concentrator machine under negative pressure, and a small amount of thickened liquid is discharged by pump after treatment; condensed water is forced out by the water pump.

 Energy Consumption Analysis&System Comparison

The production range of four- effect concentrator is between 7 and 200T/D.

① The one-effect feed liquid is heated by the heat source in vacuum and then boils and evaporates, and the low-temperature steam is cooled into condensate by the two-effect condenser and discharged outside the machine;

②After being concentrated by the one-effect evaporation, the feed liquid enters the two-effect evaporation chamber. The two-effect feed liquid is heated by the two-effect heater and then boils and evaporates. The low temperature steam is cooled into condensate by the three- effect condenser and discharged outside the machine;

③The feed liquid enters the three-effect evaporation chamber after being concentrated by the two-effect evaporation. The three-effect feed liquid is heated by the three-effect heater and then boils and evaporates. The low-temperature steam is cooled into condensate by the four-effect condenser and discharged outside the machine;
 

④ After concentration by three-effect evaporation, the feed liquid enters the four-effect evaporation chamber. The four-effect feed liquid is heated by the four-effect heater and then boils and evaporates. The low temperature steam is cooled into condensate water by the cooler and discharged outside the machine;

⑤ The cooling heat is discharged from the engine through the cooling system;

⑥ The feed liquid passes through one- effect, two- effect and three-effect. After multi-effect concentration, it is discharged outside the machine.
