Working principle

Qualified raw water is produced byMulti stage pump boostingAfter enteringcondenserperformheat exchangeThen enter each effect in sequencepreheaterThen enterOne effect evaporatorInject water from the material distributorInner wall of heating tubeMake the feed water flow in a film like manner inside the pipe and be fed by the boilersteamheatingvaporizeThe generated water dropletsSecondary steamEnter the steam water separation device from the lower end of the heating tube and be separatedPure steamEnter the next effect as heating steam, and the raw water that has not been evaporated enters the next effect, repeating the above process. The pure steam generated by the final effect enters the condenser and converges with condensed water from all effects except for the first effect for cooling. After removing insoluble gases, it becomes injection water with a temperature of 92-99 ℃.

Introduction
useDouble tube platePrevent cross contamination of multiple materials (using double or single tube plates according to customer requirements)
Raw material selection: anddistilled water、Secondary pure steamContact parts andpipeUse SS316L, and the rest use SS304.
Reasonable sealing structure: The majority of the equipment is connected by flanges, using evaporator and separation split structure, and the sealing gasket is made of PTFE,Sealed whole machine，Prevent leakage.
The three-level separation method:falling film evaporator gravity sedimentation Wire mesh foam removal.
Reasonable control of automatic discharge of qualified and unqualified distilled water: controlled by PLC using a two position three-way valve.
One effect liquid levelControl: Avoiding the whole equipment from producing unqualified water.
Electrochemical polishing: high surface smoothness; Improve the quality of stainless steelCorrosion ResistanceCan be correctMechanical polishing equipmentPolish the positions that cannot be processed, which is beneficial forMulti effect distilled water machineThe quality of the effluent is very important.
Energy conservation: due to the adoption ofThin walled heat exchange tubeEquipped with advanced material water distributors and injection water generated by each evaporator as preheatersHeating sourceIncrease the heat exchange rate of the entire device by 20%. The 5-effect machine does not require cooling water in northern regions, while in southern regions, it uses a small amount of cooling water. The 6-effect machine does not require cooling water.
Long service life: Due to the use of large space,Low speed separation, avoidedSteam Friction CorrosionGreatly extend the service life of the machine and work under the same conditions,S-type multifunctional machinecompareSpiral PlateThe service life of the multifunctional machine is extended by 5-6 years.
Internal and external argon gas protection fully automatic welding:Welding pipelineandEquipment cylinderEnsure welding quality.
Insulation layer: usingGlass WoolperhapsComposite silicate needle silk blanketThe outer layer adopts SS304 brushed board.
Control system: There are multiple control modes for users to choose from:hand movement、PLC Instrument fully automatic、 PLCTouch ScreenWait. The PLC instrument is fully automatic and can be displayed online
Temperature, conductivity, flow rate, pressure, etc. can be observed online through the PLC touch screen to monitor parameter changes (temperature, conductivity, flow rate, pressure, etc.) at any time
Understand the production status of the equipment. And can be equipped with paper or paperless recorders according to customer requirements.
