Description
Technical field
The present invention relates to a kind of marine fuel oil pre-heating system and pre-heating mean based on barrel forms, belong to marine fuel oil pre-
Thermal technology field.
Background technology
, it is necessary to which fuel oil is delivered into settling tank from holding bay in marine fuel oil induction system.Fuel oil one in holding bay
As be heavy fuel oil, its viscosity with temperature difference change very different, temperature is higher, and viscosity is lower, and such as certain a heavy fuel oil is 50
Viscosity is 380cSt at DEG C, and at 0 DEG C close to 20000cSt.Viscosity conference causes resistance during delivery pump pumps fuel to increase greatly
Plus power consumption can not even be pumped, it is therefore necessary to which progress advance to fuel oil is heated to uniform temperature and pumped again with reducing viscosity.Mesh
The traditional heating mode of preceding operation ship heavy oil is by arranging heating coil in the fuel oil tank of ship both sides, being heated by steam
Heavy oil reaches transportation by lighter condition, as shown in Figure 1.Using heating coil come heating heavy oil, reach after transport condition, Open valve,
From suction inlet pumps fuel outward.This mode shortcoming is obvious：1) capacity usage ratio is relatively low.Coil pipe heating is whole cabin fuel oil, and
Need in practice pumping amount of fuel with respect to fuel storage volume of compartment product very little, therefore considerable part heat be used to heating need not pump
The fuel oil sent, and this partial heat easily carries out heat exchange with the external world by bulkhead and is wasted.2) high temperature in a big way can be produced
Area.When holding bay is adjacent to ballast tank or cargo hold, the generation of ballast bulkhead high temperature meeting accelerated corrosion, while can also give quick to temperature
The goods of sense, suppose cereal, and coal etc. brings destruction.3) when fuel liquid level is less than heating coil, exposure is in atmosphere
Coil pipe combustion gas can be accelerated to volatilize and hard scale is formed.4) heating coil arrangement height can not be too low, when fuel liquid level is substantially lower than
When heating coil, fuel oil would become hard to be conveyed, and result in fuel oil retention.
In order to solve the problem of heating coil is brought in Fuel Delivery System, also occur in that novel fuel turns in the prior art
Changing device, its main design idea is：One small separation is set in fuel storage cabin, and separation is communicated with holding bay, past first
The high temp oil-fired in settling tank is pumped into small separation, preheating obtains a certain amount of relatively-high temperature fuel oil, reaches pumping conditions, then
Using transfer pump for fuel pumps fuel to settling tank, and so on circulate.What Fig. 2 was provided is the separation scheme in fuel storage cabin
Schematic diagram.The main purpose of separation design is to make the heating oil of injection try one's best mainly to be used to the cold fuel oil for heating regional area,
And control heated fuel oil to be unlikely to disperse very much, but concentrate in small separation, make to be extracted fuel oil and be relatively-high temperature combustion
Oil, is easy to pumping.Although this fuel oil conversion equipment can preferably avoid the problem of coil pipe heating tape is come, also more save and run into
This, but there is also shortcoming --- the quality of its pre-heat effect depends on the design of separation scheme, and irrational separation design can
Fuel oil temperature skewness, deep fat in separation can be caused to accumulate in separation top, cold and hot oily insufficient, the suction inlet oil temperature nearby that exchanges heat
Too low the problems such as, this will weaken its advantage relative to traditional coil pipe mode of heating, and operating condition possibly even increases when deteriorating
Operation cost, or even economy are inferior to coil pipe heating.Therefore, rational separation conceptual design is the pass of whole fuel-firing preheating system
Key.
Date of publication August in 2015 5 days, publication No. is CN104819080A, entitled《A kind of marine fuel oil pre-heating system and
Pre-heating mean》A kind of marine fuel oil pre-heating system is disclosed, the program employs the form of " small separation ", to the combustion in small separation
Oil is preheated, and the problem of it is present is：
1) fuel-firing preheating is uneven：Alternately opened when its pre- heat pump and delivery pump, after pre- heat pump is closed down, delivery pump is opened
Open, according to deep fat upwards, the downward principle of cold oil, now deep fat is positioned at the top of small separation, during suction conveying, feed line A
In oil temperature be unstable, and elapse over time, the oil temperature in feed line A can decline, even if strict control
The time span that delivery pump and pre- heat pump are opened, it is also difficult to ensure the stability of oil temperature.
2) deep fat and cold oil rely solely on thermal diffusion and exchanged heat, and the effect of heat exchange is not good, and the control difficulty of oil temperature is larger.
3) as oil temperature is reduced after delivery pump is opened, viscosity increase, power has a process gradually increased, causes electricity
Acc power is unstable, and the life-span is affected.
4) delivery pump and pre- heat pump need to alternately be opened according to setting program, and the operating efficiency of hot oil transfer is relatively low.

The present invention takes following technical scheme：
A kind of marine fuel oil pre-heating system based on barrel forms, between holding bay and settling tank set fuel-firing preheating and
Two pipelines are conveyed, pre- heat pump is set all the way, high temp oil-fired are provided for holding bay, another road sets delivery pump, by the weight of heating
Oil is delivered to settling tank, and two branch roads are respectively provided with the screw down nonreturn valve of respective direction, prevents that pipeline direction from misplacing；Fuel preheating pipe
Road is smaller than fuel delivery line diameter, and one inside holding bay section fuel-firing preheating pipeline B is located at corresponding fuel feed pipe
Within the A of road, A, B pipeline each set regulating valve；The flow of the A pipelines is more than the flow of B pipelines；The pipeline A and pipeline B
Between be provided with the communicating pipe C with stop valve.
The technical program optimizes design to the fuel-firing preheating system of the small separation of band of prior art：
The oil fuel tube B mouths of pipe inside holding bay are located at oil pick-up tube A inside, and both are coaxial, at the mouth of pipe deep fat with it is cold
Fry dried food ingredients life strong convection heat exchange, is sufficiently mixed, and oil pick-up tube A flow is more than oil fuel tube B, and deep fat is substantially by cold oil envelope so that
Heat is not easy diffusion and wasted, and the heat that high temp oil-fired is carried can fully effectively be used to heat the oil pick-up tube A mouths of pipe in holding bay
Cold oil, capacity usage ratio is improved.
Fuel oil note is taken out to be carried out simultaneously.Cold oil, high temp oil-fired and heated fuel oil three are all in motion state, and convection current is changed
Heat occupies main flow, and existing fuel-firing preheating scheme is basic based on thermal diffusion, and convection heat transfer intensity and speed will be much higher than heat
Diffusion, therefore, heat exchange efficiency and degree will be significantly improved, and through Simulation, after after system stable operation, being extracted combustion

Delivery pump is extracted out through pipe A, and flow Qv3, Qv3 are more than Qv2.
Further, step A) in, the A pipes of storage out of my cabin have steam to be heated with row.
Another marine fuel oil pre-heating mean based on barrel forms, comprises the following steps：
A pipeline C regulating valve) is opened, the regulating valve for the B that blinds off a line, pre- heat pump is opened, warm-up fuel enters through A pipes to be stored up
Deposit in the A pipes in cabin, holding bay, the cold oil outside B pipes is pushed into holding bay by deep fat；Enter A from preheating infusion to manage toward holding bay note
Enter the high temp oil-fired of t1 times, flow Qv1；
B) blind off a line C regulating valve, open pipeline B regulating valve, delivery pump is opened simultaneously, and two pipelines of A, B are simultaneously
Operation：Pre- heat pump is injected through pipe B, flow Qv2, and delivery pump is extracted out through pipe A, and flow Qv3, Qv3 are more than Qv2.
This pre-heating mean than former approach, the speed preheated during starting faster because deep fat directly is passed through into pipeline C
Cold oil in pipeline A is promoted to travel forward, until being pushed into holding bay, so as to quickly make to be full of high temp oil-fired in pipe A, in delivery pump
Because of low temperature fuel-viscosity variation in A pipes is excessive the delivery pump will not be caused not start during work.
The beneficial effects of the present invention are：
1) green energy conservation, cuts operating costs.Due to only heating part fuel oil, and heat is used effectively, with external world's heat
Exchange and reduce, meet green energy conservation theory, and can effectively reduce vessel operating cost.
2) the problems such as fouling brought by heating coil, steam are leaked, fuel oil is retained is avoided, and system is heated from coil pipe

5) contrast contrast publication No. is the existing scheme in CN104819080A Chinese patent literatures, and bushing type scheme can be entered
One step reduces thermal loss, and heat utilization ratio is maximized.Meanwhile, separation unnecessarily, reduces difficulty of construction and cost.Cancel
The design of small separation, without the radiating of small separation and external fluid, reduces the loss of system thermal.
6) deep fat and cold oil exchange heat by strong convection, and more preferably, the control difficulty of oil temperature is relatively low for the effect of heat exchange.
7) power stability of delivery pump and pre- heat pump, electrical machinery life is lifted.
