The upstream of interface.
The utility model it is a kind of for inject water system cooling device it is standby when, injection water connects from Pitot tube 4
Mouth N7 is flowed into, and is flowed out from the interface N8 of Pitot tube 4.Pitot tube 4 makes to branch to pipeline S1, then flow from the injection water that interface N7 is flowed into
To valve V2.At this point, valve V1, valve V3 and valve V4 are in closed state.Injection water S3 by the road is flowed into from interface N1
The tube side of heat exchanger 1, then the tube side from interface N2 outflow heat exchangers 1, then the second end of valve V3 is flow to by pipeline S4, most
The interface N8 of Pitot tube 4 is returned by pipeline S5 afterwards, returns to the injection water main line.Injection water hot if necessary at this time,
Opening valve V1 can obtain at interface N5.
Due to the utility model it is a kind of for inject water system cooling device it is standby when, pipeline S1, pipeline S2, pipe
Always injection water is filled in road S3, pipeline S4 and pipeline S5, and valve V2 is opened, valve V1, valve V3 and valve V4 are closed,
The germ-free condition of the cooling device is maintained, therefore no longer needs to sterilize and clean online before enabling.
When needing to cool down injection water, i.e., when the cooling device works, valve V2 is closed, valve V3 and valve V4
It opens.Medium is cooled down from valve V4 by cooling medium inlet pipeline 2, from the shell side of interface N3 inflow heat exchangers 1, then from interface
Injection water in the shell side of N4 outflow heat exchangers 1, with the tube side of heat exchanger 1 carries out heat exchange.Pitot tube 4 makes to flow into from interface N7
Injection water branch to pipeline S1, into combined valve 3, injection water is by valve V3, and injection water is straight without heat exchanger 1 all the way
Take back the interface N8 of Pitot tube 4.Open valve V1 at this time, in addition injection water after valve V3 comes out, passes through pipeline S4 all the way
The interface N2 of heat exchanger 1 is further separated into, into the tube side of heat exchanger 1, is cooled down in the U-tube beam 13 of heat exchanger 1.By
The injection water of cooling from the tube side of the interface N1 outflow heat exchangers 1 of heat exchanger 1, passes through pipeline S3, valve through overcooled injection water
Door V1, pipeline S2 and interface N5 flow out the cooling device, so as to obtain the injection water of cooling.
Due to the utility model it is a kind of for inject water system cooling device work when, pipeline S1, pipeline S2, pipe
It is filled with injection water always in road S3, pipeline S4 and pipeline S5, ensure that germ-free condition.And valve V2 is closed, valve V1, valve
V3 and valve V4 are opened, and have been carried out point in the second end of valve V3 through overcooled injection water and without overcooled injection water
Stream, there is no cooling dead angles.The injection water main line of injection water system is passed straight back to without overcooled injection water, conducive to note
The temperature control of injection water, reduces the energy consumption of cooling medium and steam, can reduce heat exchanging device 1 and exchange heat in jetting main line
The requirement of ability reduces waste;It is obtained through overcooled injection water from interface N5, it can be all of not causing to waste.
Finally, it avoids using tube-in-tube heat exchanger module, therefore exchange capability of heat is big, heat exchange efficiency is high, suitable for heat exchanger 1
The operating mode of interior 0~10000L/h of injection water.
When the utility model a kind of does not use for the cooling device of injecting water system, valve V1, valve are opened
V2 and valve V3, the cooling device is interior can simultaneously to discharge through overcooled injection water from interface N5 and interface N6, this is cooled down
Injection water emptying in device.
In the present embodiment, valve V1, valve V2 and valve V3 are diaphragm valve, are used to note convenient for one kind of the utility model
The cooling device of water jet system is switched fast, and valve V4 is ratio adjusting valve.Meanwhile cooling medium inlet pipeline 2 is equipped with
Sensor T1, pipeline S3 are equipped with sensor T2, and pipeline S4 is equipped with sensor T3.Sensor T1, sensor T2 and sensor
T3 connects temperature controller simultaneously, the temperature of injection water in corresponding monitoring cooling medium inlet pipeline 2, pipeline S3 and pipeline S4.
Temperature controller sets the temperature through overcooled injection water, by valve V4 proportion adjustments cool down medium flow come
Control the temperature through overcooled injection water.Before shutdown, valve V4, cut-out cooling medium supply, sensor to be passed through first are closed
The monitoring of T2 and sensor T3 after confirming that pipeline S3 is consistent with the temperature of injection water in pipeline S4, close valve V1 and valve V3,
V2 valves are opened simultaneously, are restored to standby state, maintain a kind of cooling device for being used to inject water system of the utility model
It is recycled online together with injection water system.
In addition, flow control can also be installed additional as needed on pipeline S1, pipeline S2, pipeline S3, pipeline S4 and pipeline S5
The equipment such as system, pressure sensing instruments and electric conductivity detector device.
Interface N5 may be connected directly to other equipment, can also install sample cock and realize on-line period.
In conclusion a kind of of the utility model overcomes existing three kinds for the cooling device of injecting water system and is used for
The shortcomings that injecting the cooling device of water system, without sterilize online before standby mode, there is no cooling dead angle, through overcooled note
Jetting will not flow back into injection water main line will not direct emission, reduce energy consumption and waste, and exchange capability of heat is big, exchange heat
It is efficient, suitable for injecting the operating mode of 0~10000L/h of water flow in tube side.Therefore it had not only met the laws and regulations requirement of GMP but also had accorded with
Close the requirement for flexibility and low energy consumption in actual use.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this practicality is new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above
Variation, the modification of embodiment will be all fallen in the Claims scope of the utility model.
