Description
Technical field:
The present invention relates to a kind of novel ocean platform cooled with seawater circulating tank, belong to ocean engineering field.
Technical background:
Main diesel generating set on offshore platform produces substantial amounts of heat in running, must carry out heat exchange by cooling system and could ensure the properly functioning of main frame.Cooling system is generally enclosed methods for cooling, namely by external agency cooling main frame internal recycle anti-icing fluid.At present, ocean platform cooling system peripheral medium is mainly wind and sea water.Wherein, cooled with seawater efficiency is higher.For neritic area, China Bohai Sea Gulf, sea water sediment charge is big, and mostly is the flour sand not easily filtered out, once there be stormy waves, sea water opacity rises, and causes refrigerated sea water silt content excessive, and water-cooling system efficiency will be substantially reduced, and even can not use.It addition, under conventional cooled with seawater mode, the sea water after heat exchange directly arranges sea.This part sea water carries the heat that main frame distributes, does not recycle the significant wastage causing heat resource.And under air-cooled pattern, the operation of fan, produce very big noise, cause very big infringement to field personnel's audition, do not meet HSE spirit；Further, once summer environment temperature is too high, generating set cooling effectiveness can be caused equally too low, even shut down, directly influence the normal production of platform, life.
The content of invention:
It is an object of the invention to overcome deficiency of the prior art, it is provided that one utilizes heat radiation to make seawater circulation use, be changed without the ocean platform cooled with seawater circulating tank of cooling sea water.
A kind of ocean platform cooled with seawater circulating tank, circulates four edges in bulkhead 1 in cooled with seawater and is fixed with unhurried current plate 2, circulates bulkhead 1 top in cooled with seawater and is fixed with heat dissipation grid 7 with unhurried current plate 2, forms one and half leg spaces；Being fixed with agitator 9, aerator 8, temperature monitoring 10 on heat dissipation grid 7 top, the impeller of agitator 9 is arranged in cooled with seawater circulating tank；Circulate bulkhead 1 in cooled with seawater and be externally connected to high temperature seawater inlet valve 5, low temperature seawater inlet valve 6 and high temperature seawater outlet valve 11, low temperature seawater outlet valve 12.
Such scheme also includes: connecting bypass pipe between low temperature seawater inlet valve 6 and low temperature seawater outlet valve 12, and arranges bypass valve 3 on bypass pipe；The row's of being connected to kingston valve 4 on the pipeline of high temperature seawater inlet valve 5 front end.
Agitator 9 is four, splits four corners near unhurried current plate 2 place；High temperature seawater inlet valve 5 is diagonally opposing corner with high temperature seawater outlet valve 11 arranges with low temperature seawater outlet valve 12, low temperature seawater inlet valve 6.
The present invention has a characteristic that
1, ocean platform cooled with seawater circulating tank has good heat sinking function, it is possible to by increasing the mode of air flowing, high temperature seawater is cooled off, so that sea water can constantly recycle, meets the main frame cooling requirement under severe sea condition.
2, the hot sea water in cooled with seawater circulating tank can be used as clean-out service etc., saves the energy, changes conventional cooling sea water and directly arranges the heat resource waste situation caused in sea.
3, cooled with seawater circulating tank can house and the breathing amount of sea water in compensation system, reduces the pressure that pipe-line system is caused by sea water because of heat absorption expansion
4, it enhance the cooling system adaptability to environment, noise can be reduced simultaneously, create comparatively comfortable working environment.
5, novel structure, installation, manipulation facilitate, practical；It is rectified and improved the function achieving that the method on the basis of existing ocean platform.
Accompanying drawing illustrates:
Fig. 1, a kind of Novel ocean platform cooled with seawater circulating tank schematic diagram, in figure:
1, cooled with seawater circulates bulkhead 2, unhurried current plate 3, bypass valve 4, row's kingston valve
5, high temperature seawater inlet valve 6, low temperature seawater inlet valve 7, rustless steel grid
8, aerator 9, agitator 10, temperature monitoring 11, high temperature seawater outlet valve
12, low temperature seawater outlet valve
Detailed description of the invention:
Below in conjunction with accompanying drawing, by two kinds of embodiments, the present invention will be further described.
As it is shown in figure 1, the first uses state: except temperature monitoring 10, in system, all valves, equipment initial conditions are closedown, fill low temperature seawater in cooled with seawater circulating tank.When cooling system is opened, first turn on high temperature seawater inlet valve 5, the hot sea water after main diesel generating set heat exchange is made to enter in cooled with seawater circulating tank, it is then turned on agitator 9, make high temperature seawater circulate bulkhead 1 and formation circulation in the space of the sub-circular of unhurried current plate 2 composition in cooled with seawater, accelerate heat radiation；Open aerator 8 simultaneously, take away cooled with seawater circulating tank top heat, dispel the heat further；Finally, open low temperature seawater outlet valve 12, make the sea water after heat radiation continue to participate in cooling process；Temperature monitoring 10 monitors cooled with seawater circulating tank maritime interior waters temperature in real time, once temperature is too high, report to the police, then open low temperature seawater inlet valve 6 immediately, inject from the low temperature seawater of seawater lift system, simultaneously by open high temperature seawater outlet 11 or close high temperature seawater inlet valve 5, the row's of unlatching kingston valve 4 discharges high temperature seawater；During temperature monitoring 10 high temperature alarm, also low temperature seawater inlet valve 6 and low temperature seawater outlet valve 12 can be made to remain off, opening bypass valve 3 simultaneously, directly reach the purpose injecting the low temperature seawater from seawater lift system to cooling system, the method is comparatively effective.
The second uses state: except temperature monitoring 10, in system, all valves, equipment initial conditions are closedown, fill low temperature seawater in cooled with seawater circulating tank.When cooling system is opened, first, the closed mode of low temperature seawater inlet valve 6, bypass valve 3 and high temperature seawater outlet valve 11, aerator 8 and agitator 9；It is then turned on high temperature seawater inlet valve 5 and low temperature seawater outlet valve 12, makes refrigerated sea water constantly circulate intensification；Then, after equitemperature monitor 10 high temperature alarm, close high temperature seawater inlet valve 5, the row's of unlatching kingston valve 4 and bypass valve 3 immediately, close low temperature seawater outlet valve 12, directly inject the low temperature seawater from seawater lift system to cooling system.Finally, open high temperature seawater outlet valve 11, provide hot sea water to ocean platform, be used as clean-out service etc..
