Description
Technical field
The utility model relates to a kind of with the some heat sink and comprise its water for injection system.
Background technology
The water for injection in pharmaceutical factory adopts the insulation of 70 ℃ to circulate to reduce the risk of microbial growth usually, but, certain specific use on point, according to the special requirement of processing unit and cleaning, the requirement of low temperature water is also arranged.Therefore one cover heat sink need to be set in the water for injection system, making it to provide the water for injection of 70 ℃, can guarantee again the low temperature requirement that certain uses point.At present both at home and abroad about water for injection, with what put heat sink, be designed with following two kinds:
The first is to adopt the double-tube sheet tubular heat exchanger as cooling system.The double-tube sheet tubular heat exchanger is installed on to the exit with the some valve, when with point, using, opens the double-tube sheet tubular heat exchanger, water is carried out to instantaneous cooling.This heat sink is from setting angle, owing to the some valve, being positioned at room, therefore double-tube sheet tubular heat exchanger and cold fluid valve need to be installed on inside, clean room, have dwindled producers' operable area, and have affected the integral layout aesthetic property of clean room.
From the checking angle, due to water for injection, participate in the preparation of medicine directly, need to strictly control microorganism and intracellular toxin.Owing to point, not being to use continuously, therefore must guarantee before use can be not contaminated when water for injection is put place's double-tube sheet tubular heat exchanger and follow-up pipe network by use, after use, must guarantee that the long-time stop of anti-sealing causes microbial growth with the water emptying in some place's double-tube sheet tubular heat exchanger and follow-up pipe network.Given this, need in heat sink, increase extra discharge-channel, pure steam sterilizing equipment and hydrophobic equipment also will be provided.Visible, this heat sink has strengthened checking dynamics and the fund input in pharmaceutical factory greatly.
The second is to adopt tube-in-tube interchanger based on the Pitot tube principle as cooling system.From setting angle, this device adopts modular design, and is elegant in appearance, and overcoat uses the stainless steel guard shield, and is easy to clean; From the checking angle, when water for injection did not use, fluid kept flow state always in tube side, was convenient to checking.But this tube-in-tube form has increased the heat interchanging area of interchanger, and equipment volume also can correspondingly increase.Therefore, the tube-in-tube interchanger of conventional design is only applicable to using a little of low discharge cooling requirement, as the pond of cleaning for utensil.And for needs the using a little of water of lowering the temperature in a large number, as the use of low-temperature injection water in the equipment such as Agitation Tank, because the volume of tube-in-tube interchanger is limited, its exchange capability of heat can't meet the demands.

The utility model also provides a kind of water for injection system, and described water for injection system comprises an above-mentioned heat sink of using.
Positive progressive effect of the present utility model is: what the utility model provided can provide the water for injection of larger flow with putting heat sink, and cost of investment is low, and controllability is strong.
The accompanying drawing explanation
Fig. 1 is the structural representation of embodiment in the utility model.
Embodiment
Below lift a preferred embodiment, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
As shown in Figure 1, a kind of it comprises a major cycle pipeline and a heat exchange bye-pass with a heat sink, and described major cycle pipeline comprises one first hydraulic pipe-line and a U-shaped hydraulic pipe-line.U-shaped hydraulic pipe-line is provided with manual diaphragm valve 4, and the effect of manual diaphragm valve 4 is the pressure reduction between balance major cycle pipeline and heat exchange bye-pass, guarantees the proper flow of water for injection.
Described heat exchange bye-pass comprises one first heat exchange arm, a double-tube sheet tubular heat exchanger 7, one second heat exchange arm and one the 3rd heat exchange arm that is communicated with successively.Described the first heat exchange arm is connected with described the first hydraulic pipe-line by a manual diaphragm valve 5, and manual diaphragm valve 5 uses when 7 maintenance of double-tube sheet tubular heat exchanger.The delivery conduit of described the second heat exchange arm is provided with a pneumatic normally closed diaphragm valve 3, be used to controlling the water flow of low-temperature injection water.Described the 3rd heat exchange arm is connected with described U-shaped hydraulic pipe-line by a pneumatic diaphragm valve 2 of often opening.
The expanded joint fabrication process of core component double-tube sheet tubular heat exchanger 7 adopting process maturations of the present utility model.Described with the some heat sink also include a cold fluid loop, described double-tube sheet tubular heat exchanger 7 is connected with this cold fluid loop by a cold fluid water inlet pipe and a cold fluid rising pipe respectively.Described cold fluid water inlet pipe is provided with a flow control valve 1, described the second heat exchange arm is provided with a temperature sensor 8, described temperature sensor 8 is electrically connected to described flow control valve 1, and its effect is to regulate by the temperature of controlling the second heat exchange arm the water yield that enters in the cold fluid water inlet pipe.On described cold fluid rising pipe, be provided with hand stop valve 6, during in order to maintenance, use.
With selecting heat sink when the water not, close flow control valve 1 and pneumatic normally closed diaphragm valve 3, open the pneumatic diaphragm valve 2 of often opening.Water for injection flows along the first hydraulic pipe-line and U-shaped hydraulic pipe-line on the one hand; Along the first heat exchange arm, double-tube sheet tubular heat exchanger 7, the second heat exchange arm and the 3rd heat exchange arm, flow on the one hand the right side pipeline of U-shaped hydraulic pipe-line.That is to say, major cycle pipeline and heat exchange bye-pass all can provide the water for injection of 70 ℃.
