Description
Technical field
The present invention relates to a kind of ocean platform seawater cooling cycle cabin, belong to ocean engineering field.
Technical background：Main diesel generating set on offshore platform produces substantial amounts of heat in the process of running, must be logical
Supercooling system, which carries out heat exchange, could ensure the normal operation of host.Cooling system is generally enclosed methods for cooling, that is, passes through
Circulation anti-freezing liquid in external agency cooling host.At present, external agency is mainly wind and seawater in ocean platform cooling system.Its
In, seawater cooling effectiveness is higher.By taking the neritic area of China Bohai Sea Gulf as an example, seawater sediment charge is big, and is mostly to be not easy to filter out
Flour sand, once have stormy waves, sea water opacity rise, cause refrigerated sea water silt content excessive, water-cooling system efficiency will drop significantly
It is low, or even cannot use.In addition, under the conventional seawater type of cooling, the seawater after heat exchange directly arranges sea.This part sea
The heat that host is distributed is carried in water, does not recycle the significant wastage for causing heat resource.And under air-cooled pattern, wind
The operation of fan, produces very big noise, very big infringement is caused to field personnel's hearing, does not meet HSE spirit；Also, one
Denier summer environment temperature is excessive, can equally cause generating set cooling effectiveness too low, or even shuts down, and is directly influencing platform just
Often production, life.
The content of invention：The purpose of the present invention is overcome deficiency of the prior art, there is provided one kind makes seawater using heat dissipation
Recycle, be changed without the ocean platform seawater cooling cycle cabin of cooling seawater.
A kind of ocean platform seawater cooling cycle cabin, four edges in seawater cooling cycle bulkhead 1 are fixed with
Flow slowly plate 2, and at the top of seawater cooling cycle bulkhead 1, gentle flowing plate 2 is fixed with heat dissipation grid 7, forms one and half walls
Space；Blender 9, air blower 8, temperature monitoring 10, the impeller peace of blender 9 are fixed with 7 top of heat dissipation grid
In seawater cooling cycle cabin；High temperature seawater inlet valve 5, low temperature seawater are externally connected in seawater cooling cycle bulkhead 1
Inlet valve 6 and high temperature seawater outlet valve 11, low temperature seawater outlet valve 12.
Such scheme further includes：The connecting bypass pipe between low temperature seawater inlet valve 6 and low temperature seawater outlet valve 12,
And by-passing valve 3 is set on bypass pipe；The row's of being connected with kingston valve 4 on the pipeline of 5 front end of high temperature seawater inlet valve.
Blender 9 is four, is split four corners at unhurried current plate 2；High temperature seawater inlet valve 5 and low temperature
Seawer outlet valve 12, low temperature seawater inlet valve 6 and high temperature seawater outlet valve 11 are diagonally opposing corner arrangement.
The present invention has following features：1st, ocean platform seawater cooling cycle cabin has good heat sinking function, Neng Goutong
The mode of increase air flow is crossed so that high temperature seawater cools off, so that seawater can be recycled constantly, satisfaction is severe
Host cooling under sea situation requires.
2nd, the hot sea water in seawater cooling cycle cabin can be used as clean-out service etc., save the energy, change cooling in the past and use
Heat resource caused by seawater directly arranges sea wastes situation.
3rd, seawater cooling cycle cabin can house and compensation system in seawater breathing amount, reduce seawater because heat absorption expansion to pipe
Pressure 4 caused by the system of road, it enhance adaptability of the cooling system to environment, while noise can be reduced, create more comfortable
Operating environment.
5th, structure novelty, installation, manipulation are convenient, highly practical；It is subject on the basis of existing ocean platform
Rectification achieves that the function of this method.
Brief description of the drawings：Fig. 1, a kind of ocean platform seawater cooling cycle cabin schematic diagram, in figure：1st, seawater cooling cycle cabin
Wall 2, unhurried current plate 3, by-passing valve 4, row's kingston valve 5, high temperature seawater inlet valve 6, low temperature seawater inlet valve 7, stainless steel lattice
Grid 8, air blower 9, blender 10, temperature monitoring 11, high temperature seawater outlet valve 12, low temperature seawater outlet valve are specifically real
Apply mode：Below in conjunction with the accompanying drawings, by two kinds of embodiments, the present invention will be further described.
As shown in Fig. 1, the first use state：In addition to temperature monitoring 10, all valves, equipment are initial in system
State is to close, and seawater cooling cycle fills low temperature seawater in cabin.When cooling system is opened, high temperature seawater entrance is first turned on
Valve 5, makes the hot sea water after main diesel generating set exchanges heat enter in seawater cooling cycle cabin, is then turned on blender 9,
High temperature seawater is formed circulation in the approximate circle space that seawater cooling cycle bulkhead 1 is formed with unhurried current plate 2, accelerate to dissipate
Heat；Air blower 8 is opened at the same time, takes away heat at the top of seawater cooling cycle cabin, further heat dissipation；Finally, low temperature seawater is opened to go out
Mouth valve 12, makes the seawater after heat dissipation continue to participate in cooling process；Temperature monitoring 10 monitors seawater cooling and follows in real time
Ring cabin inland sea coolant-temperature gage, alarms if temperature is excessive, then opens low temperature seawater inlet valve 6 immediately, and injection comes from seawater
The low temperature seawater of lifting system, while by opening high temperature seawater outlet 11 or closing high temperature seawater inlet valve 5, unlatching
Kingston valve 4 is arranged to discharge high temperature seawater；During 10 high temperature alarm of temperature monitoring, it can also make 6 He of low temperature seawater inlet valve
Low temperature seawater outlet valve 12 remains off, while opens by-passing valve 3, directly reaches to cooling system injection from sea
The purpose of the low temperature seawater of water lifting system, this method are more effective.
Second of use state：In addition to temperature monitoring 10, all valves, equipment initial conditions are to close in system
Close, seawater cooling cycle fills low temperature seawater in cabin.When cooling system is opened, first, low temperature seawater inlet valve 6, by-passing valve 3
With the closed mode of high temperature seawater outlet valve 11, air blower 8 and blender 9；It is then turned on high temperature seawater inlet valve 5
With low temperature seawater outlet valve 12, refrigerated sea water is set constantly to circulate heating；Then, after waiting 10 high temperature alarm of temperature monitoring, stand
Close high temperature seawater inlet valve 5, the row's of unlatching kingston valve 4 and by-passing valve 3, close low temperature seawater outlet valve 12, directly to
Cooling system injects the low temperature seawater from seawater lift system.Finally, high temperature seawater outlet valve 11 is opened, to ocean platform
Hot sea water is provided, is used as clean-out service etc..
