Multi effect distilled water machine for injection water in Xizang

Description :

　　The distilled water (water for injection) of the Xizang water for injection multi effect distillation machine is made from raw water (purified water) by high-temperature distillation. The process of high-temperature distillation is to kill microorganisms, and the secondary steam (steam water mixture) generated is discharged by multistage spiral separation, while the dry pure steam is separated. At the same time, the pure steam is utilized by the heat energy of the evaporators and preheaters of each school, and the condensate generated by the heat energy consumption is collected into the condenser, so as to obtain water for injection. The multiple effect distilled water machine will also have different factors that affect the water quality in the process of use. Common problems and solutions of Xizang water for injection multi effect distilled water machine in the water production process.

　　1. Excessive chloride ions, pH, and ammonia content

　　Scaling of the front-end electrodialysis membrane or aging of the ion exchange resin can cause it to exceed the standard.

　　Solution: Perform electrodialysis descaling or resin regeneration

　　2. Yellow impurities

　　If injection water is mixed with broken resin, insoluble impurities will appear

　　Solution: Install a filtering device in front of the multi effect distilled water machine and clean it regularly to prevent broken resin from entering the machine

　　3. Bacterial endosymycin is not qualified

　　Gas liquid separation is the main method for removing bacterial endotoxins in multi effect distilled water machines. There are several factors that can cause bacterial endotoxins to be unqualified, including the following

　　(1) Water quality: If the raw water quality is too poor and exceeds the ability of ion exchange resin to adsorb bacteria, more bacteria will enter the multi effect distilled water machine.

　　Solution: Install an ultrafiltration device in front of the multi effect distilled water machine to sterilize and ultrafiltration the raw water.

　　(2) Excessive steam pressure

　　Excessive steam pressure reflects high heat and generates excessive secondary steam pressure, which squeezes the material water droplets through the water droplet suppression device and enters the distilled water collection pipe, affecting water quality.

　　Solution: Observe the temperature on each level of the column and adjust it in a timely manner.

　　(3) Material water retention

　　Material water retention not only affects the yield of water for injection, but also affects the quality of water for injection.

　　Solution: Carefully observe the various effect mirrors of the multi effect distilled water machine, control the appropriate feed water flow rate and steam pressure, and observe the water level of the feed water in each effect.

　　(4) Leakage in the internal distilled water pipeline of the multi effect distilled water machine

　　Stainless steel pipes may experience metal aging and leakage at the welding point after long-term use

　　Solution: Immediately repair the aging area

　　(5) Improper personnel operation

　　4. Internal scaling of multi effect distilled water machine

　　Long term use of multi effect distilled water machines can easily lead to sedimentation and scaling of steam, resulting in unclean equipment, reduced evaporation area, decreased internal heat exchange capacity, affecting water output and quality, and in severe cases, causing pipeline blockage.

　　Solution: Turn on the multi effect distilled water machine, maintain a certain steam pressure, first use hydrogen peroxide for dynamic circulation treatment, and then use water to treat until qualified injection water is produced.

　　5. Other

　　In the actual production process, gradually summarize the causes and solutions of problems encountered. Operate correctly.

　　The column tube multi effect distilled water machine is a high-tech product developed and produced by Guanyu Company, relying on its own comprehensive strength, combining domestic and foreign technologies such as Finland, the United States, Italy, and collaborating with Professor Lin Zaiqi, a domestic automotive expert at Dalian University of Technology (inventor of the domestic multi effect distilled water machine).

　　Product structure of Xizang water for injection multi effect distillation machine:

　　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.

　　3 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:

　　Adopting the split type steam water four separation technology (steam water centrifugal separation, spin plate partition separation, wire mesh capture water droplet separation, and top spin 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 by Xizang water for injection 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).
