　　This product consists of 5 evaporators, 5 preheaters, 5 vapor-liquid separators, 2 condensers, feed water pumps, filters, control valves, flow meters, frames, pipelines, and controllers.

　　Product Features:

　　Evaporator:

　　By using the column tube falling film evaporation technology, the material water is evenly distributed on the inner walls of each evaporation tube, forming a water film evaporation. The upper effect pure steam provides heat energy for the lower effect evaporator, and completes evaporation and liquefaction to form distilled water.

　　Vapor liquid separator:

　　The Chongqing injection water column tube multi effect distilled water machine adopts a split type steam water four separation technology (steam water centrifugal separation, downward spiral plate partition separation, wire mesh capture water droplet separation, and upward spiral plate partition separation) to ensure lower heat source and endotoxin content in distilled water. The requirement for pure water is relatively low, and single-stage reverse osmosis (10us/cm) can produce distilled water that meets pharmacopoeia standards.

　　Preheater: adopts U-shaped tube heat exchange, with high heat exchange efficiency, good mechanical performance, and long service life.

　　Condenser: With a unique dual condenser design and a specially designed multi-channel reciprocating structure, the heat exchange is sufficient, and no dedicated cooling water is required to achieve the temperature required for distilled water.

　　Piping: The pipeline design has no water storage, no dead corners, and a low equipment failure rate. The pipeline connection adopts a new sanitary clamp connection, with polished inner and outer mirrors, arranged neatly and beautifully, and operated quickly and conveniently.

　　Configuration: Regulating valve, automatic compensating valve, throttle valve, conductivity meter, temperature meter selected from domestic and foreign high-tech products, with beautiful appearance and complete functions.

　　water source

　　The water source required for the Chongqing injection water multi effect distillation machine must be pure water produced by reverse osmosis water

　　Advantages of Guanyu Multi effect Distilled Water Machine:

　　Save steam: Save steam, effectively utilize coal resources, and achieve a savings rate of over 20%.

　　Water saving: No need for additional cooling water, saving you valuable purified water resources.

　　High effluent quality: The conductivity of distilled water is below 0.6us/cm (national standard ≤ 2us/cm), and the bacterial endotoxin is below 0.125Eu/m (national standard ≤ 0.25Eu/m)

　　Fast water output: Qualified water can be produced within 5 minutes of startup.

　　Automatic control of distilled water quality:

　　The intelligent instrument continuously displays the current conductivity of distilled water outlet and can set the qualified electrical rate value.

　　Unqualified distilled water automatically switches to discharge. And it can produce fully automatic unmanned distillation machines according to user needs (automatic alarm, startup, shutdown, pressure reduction, protection, startup for shortage, full water, low pressure, medium pressure, high pressure).

　　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 ℃.

　　Adopting double tube plate: preventing cross contamination of multiple materials (double tube plate or single tube plate can be 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, while SS304 is used for the rest of the parts.

　　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.

　　The three-stage separation method: falling film evaporation, gravity settling, and 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; Can polish positions that cannot be processed by mechanical polishing equipment, which is beneficial for multi effect distillation

　　The water quality of the water machine's effluent is very important.

　　Energy saving: Due to the use of thin-walled heat exchange tubes and advanced material water distributors, as well as the use of injection water generated by each evaporator as the heating source for the preheater, the entire system

　　The heat exchange rate of the device has 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. Greatly extend the service life of the machine, work under the same conditions, S-shaped multi effect

　　The service life of the machine is extended by 5-6 years compared to the spiral plate multi effect machine.

　　Chongqing 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 a 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 cost-effective. Other substances that evaporate when heated in the source water used to make distilled water also condense into the distilled water, 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.
