The whole cabin of insertion.The heating coil of whole fuel oil deep tank is all disposed within bilge portion, and whole cabin is heated together during heating, fuel oil heat in cabin
When exchange equilibrium reaches design temperature, required time is very long, and the steam consumption quantity of needs is big；When simultaneously fuel oil tank is incubated, need whole
Cabin is incubated together, and the steam consumption quantity of needs is also than larger.In addition, a usual fuel oil tank arranges a temperature sensor, if
The bilge is arranged on, during temperature alarming, delayed due to heat exchange, the fuel oil temperature at the top of cabin may be also very low, is not reaching to fit
When temperature；Otherwise when temperature sensor is arranged on top, again the fuel oil of possible bottom is too high during temperature alarming, causes steam to consume
The excessive loss of amount and the safety on cargo tank pipe-line system produce impact.
The content of the invention
It based on fuel oil deep tank is a whole cabin not separated that prior art fuel oil deep tank heating system is, heating coil arrangement
In bilge portion, full cabin fuel oil is heated together when fuel oil deep tank is heated, and needs saturated vapor amount big and wayward.The present invention
For this problem, there is provided the novel design method of the new arrangement of fuel oil deep tank of ship and heating system, it is mainly used in improving
Container ship shipping process efficiency of energy utilization, reduces energy waste.
In order to achieve the above object, the present invention has carried out new setting to fuel oil deep tank structure layout pattern and heating system
A kind of meter, there is provided fuel oil deep tank of ship heating system, positioned at fuel oil deep tank bottom half a horizontal guarantor with perforate is arranged
Temperature cut-off (being non-benign conduction cut-off to heat transfer)；On the cut-off and fuel oil deep tank bottom is respectively provided with heating
Pipe, the heating tube connects respectively heating system；Additionally, the fuel oil deep tank is by two intervals up and down for separating and being divided into
It is respectively provided with temperature sensor；The temperature measurement signal of the temperature sensor delivers to the heating system, for controlling heat supply.
Wherein, the perforate on cut-off is used to connect upper and lower two intervals.And separate concrete chi of the specific position by deep tank
The very little and fuel oil temperature to be kept determines.
Under a kind of optimal way, the fuel oil deep tank is 4 by two interval ratios up and down that the cut-off is divided into：1, and institute
Upper interval temperature control is stated at 30～36 DEG C, bottom interval temperature control is at 40～45 DEG C.Under this set-up mode, ship boat
Steam consumption quantity Jing needed for fuel oil tank heating process is determined and can be reduced 18% during fortune, needed for the insulating process of fuel oil tank
Steam consumption quantity can reduce 6%.
Here, it is emphasized that cut-off, the perforate on cut-off, and the temperature control of temperature sensor is all basis
The requirement of specific ship determines, determiner include the structure of deep tank, size, the control of fuel oil temperature require, external environment condition
Heat insulation effect etc..
The present invention can improve container ship shipping process efficiency of energy utilization, reduce energy waste.Wherein, fuel oil depth
Cabin is provided with a platform with little perforate near bottom, and conventional fuel oil tank is divided into upper and lower two parts.Effectively reduce upper and lower two
The heat exchange convection current for dividing so that up and down two parts are maintained at different holding temperatures after heating respectively.Fuel oil deep tank is upper and lower two
Heating coil is respectively equipped with, can be heated respectively, and be maintained at different holding temperatures.The upper and lower two parts of cargo tank are respectively equipped with
Temperature sensor, can respectively set upper and lower two-part temperature in monitoring cargo tank.The present invention being capable of effectively control combustion respectively
Temperature in cargo tank, greatly reduces the consumption of saturated vapor in actual ship shipping process, energy waste is reduced, so as to carry
High cube container ship shipping process efficiency of energy utilization.

Specific embodiment
Increase by one in fuel oil tank heating system schematic diagram of the present invention as shown in Figure 1, fuel oil deep tank 1 and carry little perforate 3
Platform 2, conventional fuel oil tank upper and lower two parts are divided into, and upper and lower two parts are respectively equipped with fuel Heating coil pipe 6 and heating coil 7,
Fuel oil tank can be heated respectively, by the obstruct of platform 2, can effectively reduce upper and lower two-part heat exchange convection current so that on
Lower two parts are maintained at different holding temperatures after heating respectively.Under a kind of optimal way, top holding temperature is set to 33 DEG C, and
Bottom cargo tank internal combustion oil thermal insulating temperature is set as 45 DEG C, reaches fuel pump transmission needs, and when bottom, high temp oil-fired is conveyed by fuel oil
After pumped, the lower temperature fuel oil on top flows into bottom cargo tank by little perforate 3, and fuel oil continues heating and thermal insulation, to meet boat
The supply of row fuel oil.Greatly reduce the consumption of saturated vapor in actual ship shipping process, reduce energy waste, Er Qieneng
Enough temperature effectively controlled respectively in fuel oil tank.
As shown in Figure 2 two parts up and down of fuel oil deep tank 1 are respectively provided with a temperature sensor 4 and temperature sensor 5, lead to
