As a China Pharmaceutical Equipment Factory, let me share with you. The
distilled water generator is a device that uses deionized water as raw material
water and uses steam to heat water for injection. It has the advantages of
reasonable structure, simple operation, high thermal efficiency, low energy
consumption, and automatic detection of water quality for injection. The water
for injection is of stable quality and high purity, and the effluent quality
complies with the Chinese Pharmacopoeia, European Pharmacopoeia, United States
Pharmacopoeia, and various regulations on "Water for Injection". The
multi-effect distilled water generator can produce high-purity steam for
sterilization and disinfection. It is an ideal equipment for water production in
hospitals, pharmaceuticals, electronics, food, and beverage industries. It is a
cGMP-compliant equipment in the pharmaceutical industry.
Purified Water Generator
Multi-effect distilled water generator is the key system of GMP. It is the key equipment of the widely used water injection preparation system. It adopts high temperature and high pressure operation to ensure stable production of pyrogen-free water for injection. In the course of use, it is found that the water production has dropped significantly, or when there is obvious scaling in the tower during routine inspection, it should be cleaned. The main reason for the formation of scale is that the residual inorganic salt in the feed water is in contact with the inner wall of the equipment for a long time and is formed under higher temperature and pressure. Since the secondary steam is used step by step in each effect, the utilization rate of industrial steam is very high, and it has obvious energy saving effect. With the increase in the number of evaporators, this energy saving effect becomes more obvious. At the same time, the amount of cooling water is also greatly reduced as the effect number increases.
How to clean the multi-effect distilled water generator:
(1) For boiler scale, sulfamic acid (NH2SO2OH) can be used, and deionized water is used to prepare a cleaning solution with a concentration of 1%. The pH value is between 1 and 2 and heated to about 60°C. Phosphoric acid (H3PO4) can also be used. Use deionized water to prepare a 2% concentration cleaning solution and heat it to about 65°C.
(2) For silica scale, ammonium difluoride (NH4HF2) can be used, and deionized water is used to prepare a solution with a concentration of 1.5% and heated to 50℃~60℃. It is also possible to use sodium hydroxide + anionic active agent to prepare a cleaning solution with a concentration of 10% and heat it to about 60°C.
