Background technology
Water is that in drug manufacture, consumption is maximum, uses the widest a kind of raw material, for the production of the preparation of process and pharmaceutical preparation.Water for pharmaceutical purposes is divided into purified water, water for injection and sterilized water for injection because its scope used is different.The former water of water for pharmaceutical purposes is usually from tap water or the phreatic water of waters corporation's supply, and former water directly can not be used as preparation or the experimental water of preparation, need carry out purifying treatment to former water.At present, existing technique is when processing former water, and pretreatment system is in the process of filtering, backwash repeatedly need be carried out, in the process of backwash, because the particulate matter such as the silt in preprocessing process, dust are more, cause the number of times of backwash more, reduce the work-ing life of reverse osmosis membrane.The stable conductivity of original RO/RO reverse osmosis unit is in lower level all the time in addition.
Summary of the invention
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of mechanical filtration systems for water for pharmaceutical purposes process in early stage, the number of backwashes of more medium filter and activated charcoal filter can be reduced, extend the work-ing life of reverse osmosis membrane.And select RO/EDI system to replace RO/RO system, make conductivity value more stable.
(2) technical scheme
The utility model discloses a kind of production water for pharmaceutical purposes device, it is characterized in that comprising: pretreatment unit, reverse osmosis unit and storage distribution device three parts; Wherein pretreatment unit comprises: raw water box, raw water pump, pasteurization cabinet, more medium filter, activated charcoal filter and accurate filter; Described pasteurization cabinet be for more medium filter in pretreatment unit and activated charcoal filter before sterilizing unit; The weighting material of described more medium filter is quartz sand; The weighting material of activated charcoal filter is gac; The weighting material of accurate filter is the soften resin of sodium form; Reverse osmosis unit comprises: one-level RO membrane reverse osmosis device and EDI second level reverse osmosis apparatus; In described one-level RO membrane reverse osmosis device, heat exchanger and antiscaling device are housed; What described reverse osmosis unit adopted is RO/EDI system, makes it under high pressure carry out reverse-osmosis treated by high-pressure pump; Storage distribution device comprises: pure water tank, distribution device and with some a pipe network device; Connected by distributing pipe line between each described device.
Further, the fresh-water tank storing one-level fresh water is housed between one-level RO membrane reverse osmosis device and EDI second level reverse osmosis apparatus.
Further, between one-level RO membrane reverse osmosis device and EDI second level reverse osmosis apparatus, de-gassing vessel is housed.
Further, interchanger and ultraviolet sterilizing lamp are housed in described distribution system.The major function room of the interchanger in distribution system maintains system water temperature, and periodically carries out Systems Sterilizer or sterilizing, is generally placed on the end return pipe net of distribution system.
(3) beneficial effect
Compared with prior art, it has following beneficial effect to the utility model: the utility model ensure that the effluent quality of water for pharmaceutical purposes meets pharmaceutical standards, and overall system architecture is simple, and stable water outlet, antifouling property are good.The utility model also proposes a kind of mechanical filtration systems for water for pharmaceutical purposes process in early stage, can reduce the number of backwashes of more medium filter and activated charcoal filter, extend the work-ing life of reverse osmosis membrane.And select RO/EDI system to replace RO/RO system, make conductivity value more stable.

Embodiment
The utility model discloses a kind of device producing water for pharmaceutical purposes, it is characterized in that comprising: pretreatment unit, reverse osmosis unit and storage distribution device three parts.Wherein pretreatment unit comprises: raw water box 1, raw water pump 2, pasteurization cabinet 3, more medium filter 4, activated charcoal filter 5 and accurate filter 6; Reverse osmosis unit comprises: one-level RO membrane reverse osmosis device 7 and EDI second level reverse osmosis apparatus 13; Storage distribution device comprises: pure water tank 15, distribution device 16 and with some a pipe network device 17.Nature tap water enters raw water box 1, is delivered to pasteurization cabinet 3, then enters more medium filter 4 successively, by activated charcoal filter 5 and accurate filter 6 by raw water pump 2; Then the water outlet of accurate filter 6 enters in first-stage reverse osmosis device 7 and second level reverse osmosis apparatus 13 successively, carries out reverse-osmosis treated, remove the salts substances in former water by high-pressure pump under the effect of high pressure; The water outlet of second level reverse osmosis apparatus 13 enters in pure water tank 15 and stores, and the pure water in last pure water tank 15 after process is dispensed to each water spot pipe network device 17 of pharmacy system again by distribution device 16.The utility model ensure that the effluent quality of water for pharmaceutical purposes meets pharmaceutical standards, and overall system architecture is simple, and stable water outlet, antifouling property are good.
Described pasteurization cabinet 3 be for more medium filter in pretreatment unit 4 and activated charcoal filter 5 before sterilizing unit; Pasteurization cabinet is that liquid heat is continued 30 minutes to 80 to 85 degrees Celsius, is used for killing causing disease, rotten or unwanted organism of fermentation, and bacterial endotoxin can be can be controlled in 5EU/ml, be a good water system of pre-treatment.
Further, the more medium filter 4 in described pretreatment unit is filled stone sand mostly, and its Main Function utilizes membrane filtration, permeation filtration and contact percolation effect, removes large granular impurity, suspended substance, colloid etc. in water; Activated charcoal filter 5 mainly by objectionable impuritiess such as the free chlorine in the adsorptive power removal water of activated carbon surface pore, microorganism, organism and part heavy metals, reaches the object of taste removal except look, impacts to prevent their low reverse osmosis membrane apparatus; Accurate filter 6 is mainly exchanged the calcium ion in water, magnesium ion by the soften resin of sodium form, thus filters out calcium ion and magnesium ion, removes the hardness in water.
Further, in described one-level RO membrane reverse osmosis device 7, heat exchanger 9 and antiscaling device 10 are housed; Optimal working temp due to reverse osmosis membrane is 25 DEG C, and its water production rate is maximum at this temperature, so utilize heat exchanger 9 heat to the water entering reverse osmosis or lower the temperature, regulates inflow temperature to remain on (25 ± 2) DEG C.Described antiscaling device 10 Main Function is the solvability relatively increasing scale forming matter in water, and to prevent the material such as calcium carbonate, calcium sulfate to the obstruction of film, it also can prevent iron ion from blocking film simultaneously.
Further, described reverse osmosis unit replaces original RO/RO system by RO/EDI system, and Main Function makes it under high pressure carry out reverse-osmosis treated by high-pressure pump, removes the salts substances in former water.
Further, the fresh-water tank 12 storing one-level fresh water is housed between one-level RO membrane reverse osmosis device and EDI second level reverse osmosis apparatus.
Further, de-gassing vessel 11 is housed between one-level RO membrane reverse osmosis device and EDI second level reverse osmosis apparatus, mainly
Be used for the reduction CO in water
2to 5-10mg/l, increase the possibility of bacterial load, the growth of anti-bacteria.
Further, in described distribution system 16, interchanger and ultraviolet sterilizing lamp are housed.The major function room of the interchanger in distribution system maintains system water temperature, and periodically carries out Systems Sterilizer or sterilizing, is generally placed on the end return pipe net of distribution system.
