Shanxi injection water tube multi effect distilled water machine

Description :

　　The Shanxi injection water multi effect distillation machine is a device that uses deionized water as raw material water and steam heating to produce injection water. It has the advantages of reasonable structure, simple operation, high thermal efficiency, low energy consumption, and automatic detection of injection water quality. The injection water produced by this machine has stable water quality and high purity, and the effluent water quality meets the various regulations of the Chinese Pharmacopoeia, European Pharmacopoeia, United States Pharmacopoeia, and Shanxi injection water multi effect distillation machine for "injection water". This machine is capable of producing high-purity steam for sterilization and disinfection purposes, and is an ideal equipment for water production in hospitals, pharmaceuticals, electronics, food, and beverage industries. The working principle of the multi effect distilled water machine is

　　Qualified raw water is pressurized by multi-stage pumps and enters the condenser for heat exchange. It then sequentially enters the preheaters of each effect, and then enters the first effect evaporator where it is sprayed onto the inner wall of the heating tube through the material water distributor, causing the material water to flow in a film like manner inside the tube and be heated and vaporized by steam from the boiler. The secondary steam carrying water droplets generated enters the steam water separation device from the lower end of the heating tube, and the separated pure steam enters the next effect as heating steam. The raw water that has not been evaporated enters the next effect, and the above process is repeated. 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 ℃.

　　The Shanxi injection water column multi effect distilled water machine adopts double tube plate: to prevent cross contamination of multiple materials (double tube plate or single tube plate is used according to customer requirements)

　　Raw material selection: SS316L is used for the parts and pipelines in contact with distilled water and secondary pure steam

　　Reasonable sealing structure: The majority of the equipment adopts flange connection, evaporator and separation split structure, and PTFE sealing gasket to seal the whole machine and prevent leakage.

　　Unique three-stage separation method: falling film evaporation+gravity settling+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 level control: avoids unqualified water output of the entire equipment.

　　Electrochemical polishing: high surface smoothness; Improve the corrosion resistance of stainless steel; Polishing can be applied to areas that mechanical polishing equipment cannot handle, which is crucial for the effluent quality of multi effect distilled water machines.

　　Energy saving: Due to the use of thin-walled heat exchange tubes and * * material water distributors, as well as the use of injection water generated by each evaporator as the heating source for the preheater, the overall heat exchange rate of the equipment is increased 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 and low-speed separation, it avoids steam friction and corrosion. The service life of the machine is greatly extended. Under the same working conditions, the S-type multi effect machine has a 5-6 year longer service life than the spiral plate multi effect machine.

　　Fully automatic welding with internal and external argon gas protection: welding pipelines and equipment cylinders to ensure welding quality.

　　Control system: There are multiple control modes for users to choose from: manual, PLC+instrument fully automatic, PLC+touch screen, etc. The PLC+instrument is fully automatic and can display temperature, conductivity, flow rate, pressure, etc. online. The PLC+touch screen can observe parameter changes (temperature, conductivity, flow rate, pressure, etc.) online through the touch screen, and keep track of the equipment production status at any time. And can be equipped with paper or paperless recorders according to customer requirements.

　　Different heating methods for heat sources: boiler steam is used to enter the evaporator, while the preheater uses heated raw water; LDF uses boiler steam to enter both the evaporator and preheater simultaneously.

　　The separation methods are different: LDS uses falling film evaporation+gravity settling+wire mesh foam removal, while LDF uses falling film evaporation+gravity settling+spiral orbit centrifugal separation.

　　Shanxi injection water multi effect distillation machine refers to a machine that uses distillation methods to prepare pure water. It can be distilled once or multiple times. After a distillation of water, non-volatile components remain in the container and are removed. Volatile components enter the initial fraction of distilled water, usually only collecting the middle part of the fraction, which accounts for about 60%. To obtain purer water, an alkaline potassium permanganate solution can be added to distilled water to remove organic matter and carbon dioxide; Add non-volatile acid to convert ammonia into non-volatile ammonium salt. Due to the presence of small amounts of water-soluble components in glass, quartz distillation vessels should be used for secondary or multiple distillations to obtain very pure water. The resulting pure water should be stored in quartz or silver containers.

　　The working principle of Shanxi injection water multi effect distilled water machine is to boil the source water and evaporate it for condensation and recovery, which requires a large amount of heat energy and is not too low in cost. Other substances in the source water used to produce distilled water that evaporate when exposed to heat will also condense into the distilled water as the distilled water is generated, such as harmful phenols, benzene compounds, and even mercury that can evaporate. To obtain pure water or ultrapure water, it is necessary to undergo two or three distillations and add other purification methods.

　　The application of distilled water machine: In daily life, when it is generally related to machines and appliances, the main function of distilled water is that it is non-conductive, ensuring stable machine operation and extending the service life of appliances. In the pharmaceutical industry, the function of distilled water is due to its low permeability. Rinse the surgical wound with distilled water to allow any remaining cells in the wound to absorb water, swell, rupture, necrotize, and lose their activity, avoiding implantation and growth on the wound. Some chemistry experiments in school require the use of distilled water, which utilizes distilled water without electrolytes, free ions, or impurities. You need to analyze the specific problem to see if it utilizes its non-conductive properties, low permeability, or the absence of other ions that do not undergo chemical reactions.

　　Characteristics of a distilled water machine: It can add alkaline potassium permanganate solution to distilled water to remove organic matter and carbon dioxide; Add non-volatile acids (sulfuric acid or phosphoric acid) to make ammonia a non-volatile ammonium salt. Due to the presence of small amounts of water-soluble components in glass, quartz distillation vessels should be used for secondary or multiple distillations to obtain very pure water. The resulting pure water should be stored in quartz or silver containers.
