Description
Technical field
The utility model belongs to water-treatment technology field, particularly relates to a kind of aseptic medical injection water treating equipment.
Background technology
At present, the aseptic medical injection water that uses in the hospital is produced with water treating equipment by aseptic medical injection usually, is specially former water pre-treatment means, and----the outer conveying device of purified water device for making----storage is produced.Facility in the former water pre-treatment means has different settings because of raw water quality is different, can comprise one or more in the following facility: facilities such as water pump, sand-bed filter, ferrimanganic strainer, softening agent, carbon filter, accurate filter.Facility in the purified water device for making, also the water quality because of former water is different, generally includes first-stage reverse osmosis, two-pass reverse osmosis and off-set facility.The setting of storing the facility in the outer conveying device, different because of requirement to pure water, generally include sterilizing unit, water tank etc.
The making processes of aseptic medical injection water is as follows: former water enters sand-bed filter by the water pump supercharging, metallicses such as filtering suspended substance mechanical impurity and ferrimanganic, pass through the sodium resin in the softening agent again, with calcium ions and magnesium ions exchange becoming softening water in the water, enter carbon filter by activated carbon adsorption gas (as chlorine), organism, some and bacterium and pyrogen, purpose is the damage that reduces reverse osmosis membrane, again through accurate filter, in order to avoid enter reverse osmosis membrane and result in blockage greater than 5 microns particle.The water of the former water pre-treatment means of process just can enter reverse osmosis membrane by the topping-up pump supercharging, but the most of inorganic salt of filtering, 99% particulate (particle diameter＞0.1 μ m), bacterium, virus, pyrogen and organism (molecular weight＞300) etc. pass through the two-pass reverse osmosis film again.Through the water of purified water device for making, reached the requirement of aseptic medical injection water by being difficult in sterilizing unit (as the ultraviolet radiation device) sterilization in the outer conveying device of storage, the water of decomposition by the little organic compound of activated carbon adsorption at last.
Reverse osmosis membrane can remove anhydrate middle majority of particles, inorganic salt, organism etc., and the technology that two reverse osmosis equipments are united use is called the twin-stage reverse osmosis process, and two reverse osmosis equipments are called the firsts and seconds reverse osmosis.The pharmacopeia of the U.S. the 19th edition, 20 editions, 21 editions is recorded reverse osmosis method already for producing the official method of medical aseptic water for injection.Because the soup that foreign material such as institute's containing metal, salt, ion, organism are mixed with along with water for injection in the water enters human vas, will cause serious consequence.And how many foreign material content such as metal, salt, ion, organism are the principal elements that influences water conductivity, therefore abroad with specific conductivity as weighing one of aseptic medical injection quality of water index.24 editions aseptic medical injection electrical conductivity of waters of regulation of American Pharmacopeia are 1.33 μ S (25 ℃), and Europe pharmacopeia ([in 2000) then is defined as and is not more than 1.1 μ S/cm (25 ℃), heavy metal content is that 0.1 μ g/ml, endotoxin content 0.25EM/ml are following, total organic carbon is not more than 500 μ g/L.Because it is big that the geologic feature of China forms the water quality difference of various places, the many characteristics of organic pollutant content such as heavy metal substance such as manganese, iron and muriate, carbonic acid gas, readily oxidizable substance, non-volatile matter in the water.Hospital generally adopts the two-pass reverse osmosis method to produce aseptic medical injection water at present, the metal removal rate of first-stage reverse osmosis film approximately is 97%, therefore through specific conductivity behind the two-pass reverse osmosis generally at 1.33～2 μ S/cm greater than 1.1 μ S/cm, do not reach Europe officinal index, but the heavy metal content that can meet domestic pharmacopeia regulation is 0.5 μ g/ml requirement.Water conveying device outside storage is sterilized by sterilizing unit ultraviolet ray device, the intensity of illumination of UV-irradiation can not be evenly, there are part bacterium and virus not to be killed, the remains of bacterium and the virus of being killed still exist in the water, in the water supply mobile pipeline, will form microbial film gradually and grow a large amount of bacteriums, cause endotoxin content to increase.The employed aseptic medical injection water of comprehensive the above present China hospital can not meet Europe pharmacopeia set quota.
Summary of the invention
The purpose of this utility model is to provide a kind of aseptic medical injection water treating equipment that can produce aseptic medical injection water with the two steps ro method.
The purpose of this utility model realizes in the following manner: it comprises the aseptic medical injection water treating equipment of former water pre-treatment means, purified water device for making, the outer conveying device of storage, it is characterized in that described purified water device for making comprise by the first-stage reverse osmosis mechanism of joining successively, water tank, mixed bed, alkali pump, resin chips pounce on catch device, two-pass reverse osmosis mechanism constitutes; The outer conveying device of described storage is by the sterilizing unit that joins successively, ultra-fine filter, water tank, and membrane filter, delivery valve constitute, and are provided with delivery valve between described membrane filter and the water tank.
Compared with prior art, reasonable in design, the characteristics that the purity of the water after the processing is high, owing to adopted the middle ion exchange unit----of having connected of first-stage reverse osmosis mechanism and two-pass reverse osmosis mechanism to mix bed, make heavy metal ion be reduced to below the 0.1 μ g/ml, reduced electrical conductivity of water, the purifying electrical conductivity of water of this moment can reach 0.063 μ s/cm～0.1 μ s/cm.Described mixed bed can mix the zwitterion resin equably by a certain percentage and is contained in the same container, and the water after processed is by mixing the H that bed is produced
+, OH
-Ion generates the very low water of solubleness immediately, improved ratio of desalinization, permutoid reaction is carried out thoroughly, the metal ion clearance is near 100%, improved the purity height of water, the gegenion when seldom forming positively charged ion or anionresin owing to reaction process has reduced and has stopped up the material that mixes bed, prolong the work-ing life of mixed bed greatly, reduced cost.
