PRINCIPLE

The qualified raw water is pressurized by the multi-stage pump and then entersthe pipeline condenser 2, uses waste heat to heat the raw water, and then entersthe preheater 2 and the preheater 1, After heat exchange, it enters the evaporatorand is sprayed into the heating tube by the material water distributor.Make material water to flow in a film status on the tube wall, which will be heatedand vaporized by industrial steam. The secondary steam with water dropletsgenerated after gasification enters the steamwater separation device from thelower end ofthe evaporation chamber, and becomes ultra-pure steam afterthree-stage separation.

FEATURE

1.Structure: external preheater, condenser and first efect evaporator are designed with double tubesheets,and the inner tubesheet expansion welding processis adopted to avoid cross conta mination.

2. separation device: with falling film evaporation, gravity separation and spiral flow three-stage separation.

3, Material: $$316L is used for all parts in contact with raw water, water for injection and secondary pure steam,

4.Heat presenvation and heatinsulaion:evaporator,preheater and condenser are all made of aluminoslicate needle felt, with good extensibility,ight welghtexcellent heat insulation and strong stability.

5, Surface treatment:internal and exteral surace elecrochemical polishing, effectively ensure the surace finish of stainless steel

6.Enercysaving and consumolon reduction: dueto the secondany steam being used steo by steo in each eficiency.the mull effect distlled water machine hasa high utilization rate of industrial steam and has obwious energyi saving effect.With the increase of evaporator efficiency, the energy-saving effect is moreincrease of efficiency,The five effect distilled water machine produced by ourobvious, At the same time, the amount of coolina water also decreascomoanvuses a smalamount oi coolina water, and the six ellect distilrmachine doesnotneed coolna water

7. stainless steel pipe shallbe used as far as possilble to drectly stretch the elbow to avold welding.Asfar as possible automatic welding with argon protectionside forming process) to ensure the welding quality and electrochemicalshall be used for pipeline and fttinas weldments(sinale sidewvelding andpolishing after welding.

8. Provide endoscopy photos, solder joint diagram, pressure test and picking passivation report, system design documents and other verification data.

9.The control system adopts HiMl +PlC automatic contro, and the operatlon interface is simple, Various communication modes can be provided, Control systemauthority level: at least three levels of authority can be set.

10. 0nline monitoring of conductivity,temperature and flow parameters. The recorder can select paperless recorder or paper recorder to recordand print the key parameters.

11. The control system can be equipped with electronic signature and electronic record,so that the system control has udit tral function, and meetsthe requirements ofgamp s and 21 CFR Part 11.
