Description
Technical field
The present invention relates to salt water cooling system, more specifically, it relates to oceanographic engineering depressed place maritime interior waters cooling system.
Background technology
The system debugging of oceanographic engineering is the Focal point and difficult point that platform is built, general debugging cycle is about 12 months, the singularity built due to oceanographic engineering and complicacy, early stage builds and has often tied up the more time, and reserved debugging cycle can not get ensureing, leave the time less of debugging for, directly affects handing over smoothly of platform. Existing oceanographic engineering utilizes platform to carry sea water cooling pump extracting seawater mostly after lower water, with cooling system of fresh water heat exchange, generator can run after possessing this condition and carry out system debugging, fails effectively to utilize the timing node in dock to carry out system debugging, and what often cause project drags the phase.
Summary of the invention
It is desirable to provide a kind of oceanographic engineering carries out cooling the system of debugging based on seawater outside depressed place.
In order to achieve the above object, the present invention provides debugging salt water cooling system in a kind of oceanographic engineering dock, it is characterized in that, in the oceanographic engineering platform in graving dry dock cooling system of fresh water pipeline comprise interchanger, fresh water cooling pump, realization cooling generator and user; The branch road connecting expansion tank is set between described interchanger and described fresh water cooling pump; The cooled with seawater pipeline exchanged for described exchanger heat comprises submersible pump outside the depressed place providing seawater; Seawater is delivered to through suction box and is drained into outside the side of a ship through seawater vent line after described interchanger; One section of removable spool is set between described suction box and described interchanger; The setup of entrances and exits valve body of described removable spool; In addition, arrange seawater discharged to the emptying pump outside depressed place in described depressed place.
In addition, described expansion tank arranges water supplement port.
Outer for dock seawater is caused salt water cooling system by submersible pump and relevant pipeline by the present invention, realize the heat exchange with cooling system of fresh water, for the normal operation creation condition of generator, and then realize the object carrying out system debugging in oceanographic engineering dock, and the seawater that salt water cooling system is discharged can be drained into outside dock by emptying pump, it is ensured that in dock, other construction operations are not influenced. Debugging salt water cooling system design in dock of the present invention, make full use of the construction phase of oceanographic engineering in dock, system debugging can be carried out after water under pattern of breaking the normal procedure and platform, create the system debugging condition being equal under water, win valuable initial failure period, laid the foundation for whole project completes smoothly.
Accompanying drawing explanation
Fig. 1 is debugging salt water cooling system principle schematic in oceanographic engineering dock of the present invention.
Embodiment
Debugging salt water cooling system in a kind of oceanographic engineering dock as shown in Figure 1, in the oceanographic engineering platform A in graving dry dock 1, cooling system of fresh water pipeline 2 comprises interchanger 5, fresh water cooling pump 6, the generator realizing cooling and user; The branch road connecting expansion tank 8 is set between described interchanger 5 and described fresh water cooling pump 6. Submersible pump 12 outside the depressed place that seawater is provided is comprised for the cooled with seawater pipeline of described interchanger 5 heat exchange; Seawater is delivered to through suction box 14 and is drained into the side of a ship outer 3 through seawater vent line 4 after described interchanger 5; Wherein, one section of removable spool 11 is set between described suction box 14 and described interchanger 5; The setup of entrances and exits valve body of described removable spool 11; In addition, arrange in described depressed place by seawater discharged to outside depressed place 10 emptying pump 9. In figure, described expansion tank 8 arranges water supplement port 7.
Debugging salt water cooling system design in oceanographic engineering dock of the present invention, comprises removable spool, submersible pump, interim pipeline and web member and emptying pump, and described removable spool 11 is in order to replace sea water cooling pump; Described interim pipeline and web member are connected submersible pump 12 and suction box 14 sea intake pipe; The seawater that described emptying pump 9 collects in dock in order to discharge is to, outside depressed place, number in the figure 13 represents seawater.
The present invention provides debugging salt water cooling system design in a kind of oceanographic engineering dock, primarily of removable spool, submersible pump, interim pipeline and the composition such as web member and emptying pump, as shown in Figure 1, by submersible pump and relevant pipeline, outer for dock seawater is caused salt water cooling system, realize the heat exchange with cooling system of fresh water, for the normal operation creation condition of generator, and then realize the object carrying out system debugging in oceanographic engineering dock, and the seawater that salt water cooling system is discharged can be drained into outside dock by emptying pump, guarantee that in dock, other construction operations are not influenced.
Step 1, changes platform with removable spool 11 and carries sea water cooling pump, and with fastening piece tight; Discharge capacity and the lift of submersible pump 12 are determined through calculation and check, and pump is placed in the outer seawater of dock, and its outlet is connected with suction box 14 sea intake pipe by interim pipeline and web member. Usually all arranging emptying pump 9 in dock, for discharging the seawater collected, its discharge capacity need to meet the maximum water yield collected in dock.
Step 2, platform related system mechanical complete and after possessing debugging condition, on seawater, fresh water pipeline, valve part is placed in opened condition, run submersible pump 12, refrigerated sea water enters interchanger, it is achieved with the heat exchange of fresh-water system, and then makes generator and other equipment possess operation and debugging condition. Emptying pump 14 is collected situation depending on the water yield in dock and can be determined whether to run.
The above; it is only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; any it is familiar with those skilled in the art in the technical scope of present disclosure; technical scheme and invention design thereof according to the present invention are equal to replacement or are changed, and all should be encompassed within protection scope of the present invention.
