Description
Technical field
The utility model relates to a kind of preparation system of injection high purity water, belongs to water-treatment technology field.
Background technology
In the water of the various quality of using in pharmaceutical industry, water for injection (WFI) is all most important in water for pharmaceutical purposes all the time, also just higher to its specification of quality.At present, Chinese pharmaceutical enterprises generally all adopts distillation method to prepare water for injection, and this technology has obtained the approval of industry, and technology is comparative maturity also.Yet, also exist deficiency, be mainly reflected in safety and energy consumption, stilling chamber cost is very high, the source water of distillation must be purified water (purified water must meet the chemical pure cleanliness standard the same with water for injection) and use clean steam as heating medium, so their running cost is very high, and there is certain potential safety hazard in distillation tower.
It is the new technology growing up in the 60's that reverse osmosis membrane is prepared Purewater Technique, because its operating procedure is simple, desalination and depyrogenation efficiency are high and both economical, and American Pharmacopeia, since 19 editions, records reverse osmosis method as the official method of preparing water for injection continuously.But there is following deficiency in it: install more complicated, and preparation pure water conductivity unstable.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of preparation system of injection high purity water is provided.
The utility model solves the technical scheme that its technical problem adopts:
The preparation system of injection high purity water, comprise the former water storage tank connecting successively, one-level infusion pump, grade one filter, secondary filter, tertiary filter, reverse osmosis unit, relay tank, also comprise controlling organization, described relay tank rear end is connected with mixed bed and high purity water storage tank in turn, conductivity meter is installed on the pipeline between described relay tank and mixed bed successively, the first control valve and secondary infusion pump, between described conductivity meter and the first control valve, be also provided with branch road, described branch road is provided with the second control valve, the exit end of described branch road is communicated with high purity water storage tank, described conductivity meter, the first control valve, secondary infusion pump is all connected with controlling organization with the second control valve.
Pure water conductivity prepared by existing reverse osmosis system is unstable, the utility model has increased mixed bed after reverse osmosis unit for this reason, mixed bed can effectively be removed the mineral substance in pure water, consider saving processing cost, the factor of energy consumption, the utility model has designed branch road, when the pure water conductivity prepared when reverse osmosis system is qualified, directly by branch road, entered in high purity water storage tank, when the pure water conductivity prepared when reverse osmosis system is defective, through main line, by secondary infusion pump, pump in mixed bed and obtain qualified high purity water after processing, for achieving the above object, conductivity meter, the first control valve, secondary infusion pump, the second control valve forms Controlling System together with controlling organization, automatically control efficient operation of the present utility model.
As preferably, the filtration medium that described grade one filter adopts is coarse sand.
As preferably, the filtration medium that described secondary filter adopts is gac.
As preferably, it is the micropore filter element of≤5 μ m that described tertiary filter adopts filtering accuracy.
As preferably, described mixed bed contains resin cation (R.C.) and resin anion(R.A).
As preferably
,described the first control valve and the second control valve are electrically-controlled valve.
The beneficial effects of the utility model are: simple in structure, and dependable performance, easy to operate, stay-in-grade high purity water can be obtained, and processing cost and energy consumption can be saved.
