Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a two-stage reverse osmosis water purification device for pharmaceutical use. Background Art

[0002] Purified water, also known as deionized water, refers to water from which suspended matter and inorganic cation and anion impurities have been removed, and difficult-to-remove electrolytes have been removed to a certain extent. It is generally produced by membrane separation, ion exchange, or a combination of these methods. Since purified water has been treated to remove bacteria, viruses, organic matter, inorganic salts, and other impurities, it can reduce potential threats to the safety and effectiveness of drugs and has been widely used in the pharmaceutical industry.

[0003] Traditional purified water preparation methods such as distillation and ion exchange can no longer meet the high standards of water quality required by modern pharmaceutical processes. Although the existing single-stage reverse osmosis purification device has a certain effect in removing impurities in water, its treatment efficiency and effluent water quality are still insufficient. In addition, when treating high-concentration contaminated water, the single-stage reverse osmosis device is prone to membrane contamination and failure, which requires frequent maintenance or replacement of the reverse osmosis membrane, increasing production costs. Therefore, a two-stage reverse osmosis water purification device for pharmaceutical use is proposed to solve the above-mentioned problems. Utility Model Content

The raw water is pretreated by a multi-media filter and an activated carbon filter box before passing through the reverse osmosis membrane, which can effectively remove suspended solids, organic matter and odor in the water. By pretreating the raw water, the risk of contamination of the reverse osmosis membrane can be reduced, thereby improving the operating efficiency and stability of the entire system.

[0024] Working principle: When in use, the raw water first enters the multi-media filter 7 through the first water inlet pipe 8, and the large particles of impurities and suspended solids in the water are removed by the multi-media filter 7. Subsequently, the raw water enters the activated carbon filter box 5 through the second water outlet pipe 6, and the activated carbon filter box 5 removes some organic matter, chlorine and other substances that may affect the subsequent membranes in the water to reduce membrane pollution. After that, the raw water is transported to the primary reverse osmosis membrane 201 through the first water outlet pipe 4, the first high-pressure pump 204, the first water inlet main pipe 203 and the first water inlet branch pipe 202. In the primary reverse osmosis membrane 201, the water is subjected to the high pressure of the first high-pressure pump 204 and passes through the primary reverse osmosis membrane 201 to remove most of the salts and impurities. The treated water flows out from the first water outlet branch pipe 205 and merges into the first water outlet main pipe 206. The water after primary treatment is further transported by the second high-pressure pump 304 to The secondary reverse osmosis membrane 301 further removes trace amounts of ions and organic pollutants in the secondary reverse osmosis membrane 301 to ensure high water purity.
