Oil tank local fast heating device
(1) technical field
The utility model relates to a kind of temperature booster that is used for pouring out the oil heating to oil tank, particularly a kind of oil tank local fast heating device.
(2) background technology
At present, in the oil storage and transportation process, to heating of oil product in the jar, basically still adopt jar interior traditional approachs such as shell and tube or circular duct heater of installing, make jar interior oil product by with the interchange of heat of hot media (generally being hot media) with the saturated steam, realize intensification to oil product, reduce viscosity, improve its flowing power, so that the conveying of pump.This traditional heating mode has following drawback:
1, the low steam consumption quantity of heat exchange efficiency is big.Tradition jar internal heater is a kind of heat transfer free convection of leaving standstill formula to the heating of oil product, and its coefficient of heat release is extremely low.Because heat exchange efficiency is low, the condensate temperature height often follows a large amount of steam to discharge.Simultaneously, since too high in the oil product temperature on heating pipe surface, be detained for a long time in the heat exchanger tube high temperature face, very easily producing analyte, knot gathers in the heat exchanger tube surface, and coking easily seriously hinders the transmission of heat, influences heat exchange efficiency.
2, heat process is very uneconomical, and production efficiency is low.In the time only need pouring out a spot of oil product, also to the oil product in whole jar all be heated.
3, jar interior each several part oil product temperature is unbalanced.Oil product temperature near temperature booster is higher, and is lower away from the oil product temperature of temperature booster, and the temperature of oil pumping point is lower, influences the oil-out flowing power.
4, influence oil quality.Repeatedly oil product in the jar is heated, produce a large amount of tiny analytes in the heat process, oil product colourity quality is produced certain influence, increased the cost of post-processed.
(3) summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of to carry out patterned heat, oil tank local fast heating device that the efficiency of heating surface is high to pouring out oil product.
The utility model is achieved through the following technical solutions:
The utility model oil tank local fast heating device is made up of the hollow housing of inserting from tank bottom, the heating pipe that is fixed in the housing, and described housing has the oil suction that is positioned at oil tank and is positioned at the outer oil outlet of oil tank.
The utility model oil tank local fast heating device, described oil suction is positioned at housing bottom, and Open Side Down.
The utility model oil tank local fast heating device, described heating pipe adopts wavy eddy current molten bubble.
The utility model oil tank local fast heating device, the steam admission port place of described heating pipe is fixed with the temperature control valve of control oil product temperature.
The beneficial effects of the utility model are:
(1) oil suction that is positioned at the housing of tank bottom and is positioned at housing bottom makes oil product localized hyperthermia, charing can not occur, oil quality and temperature booster heat transfer efficiency have been guaranteed, make the tank nozzle temperature the highest, guaranteed to pour out the oil product flowing power, avoided simultaneously repeatedly oil product in the jar being heated, guaranteed that oil product colourity has reduced the cost that oil product is handled;
(2) wavy eddy current molten bubble makes oil product both obtain suitably, heat fully, does not have the possibility of coking, decomposition again, and firing rate is fast, the heat transfer efficiency height.
(3) can quantitatively heat oil product, how much need pour out how many heating.
(4) temperature control valve can be according to the turnover temperature of oil product and the oily flow control steam amount of feeding that falls.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model,
Among the figure: 1, oil tank, 2, housing, 3, heating pipe, 4, oil suction, 5, oil outlet, 6, admission port.
(5) specific embodiment
Below in conjunction with accompanying drawing the utility model is specified.
Fig. 1 is a structural representation of the present utility model, form by the temperature booster housing 2 of the hollow that is fixed on oil tank 1 bottom, the heating pipe 3 that is fixed in the housing 2, described housing 2 has oil suction 4 that is positioned at oil tank 1 internal heater housing 2 bottoms and the oil outlet 5 that is positioned at outside the oil tank 1, oil suction 4 is positioned at housing 2 bottoms, and heating pipe 3 adopts wavy eddy current molten bubble.Oil body in the oil tank 1 enters oil suction 4 from oil tank 1 bottom, flows out oil tank 1 through wavy eddy current molten bubble heating back.
The surface of described wavy eddy current molten bubble scribbles heat conducting film, and undulate can make fluid produce eddy current.
Steam admission port 6 places of heating pipe 3 are fixed with the temperature control valve of control oil product temperature, the detection of oil product temperature out is controlled the steam inlet steam input of heat exchanger by temperature-sensing probe, thereby guarantee the constant of oil product temperature, realized automation control, according to the turnover temperature of oil product and the oily flow control steam amount of feeding that falls.
Be to the utility model oil tank local fast heating device analysis on energy saving effect below:
Is that novel oil tank rapid heater heating 150BS type oil product on the 500M3 oil tank is an example with Sinopec lubricating oil Jinan ancillary firm at volume, and by operation test and former tube heater relatively, resultant result is highly desirable, and is as shown in the table:

As can be seen from the above table, under equal working condition, adopt by " local fast heating device ", oil product is in extraction process:
1, production time shortens. production system reaction fast and flexible, and one, two days operating process of former need can be finished in a few hours, and rhythm of production is accelerated, and efficient improves.
2, condensate temperature reduces. and the heat energy of steam is fully used, and heat exchange efficiency, energy utilization rate improve.
3, steam consumption quantity significantly reduces, and energy-saving effect is promising significantly.
