Refer to Fig. 1, the present embodiment provides a kind of crude(oil)unit, and it includes atmospheric tower 100, often pushes up oil circulation device
200, chiller 300 and products pot 400.
Wherein, atmospheric tower 100 is prior art, is mainly used in the distillation of crude oil, and it is internally provided with multiple tower tray, multiple
Tower tray is arranged along short transverse interval.
Often top oil circulation device 200 includes oil-gas transportation pump 210 and often pushes up heat exchanger, often push up heat exchanger be provided with three and
It is respectively First Heat Exchanger the 220, second heat exchanger 230 and the 3rd heat exchanger 240.Oil-gas transportation pump 210 and atmospheric tower 100
Inner space, First Heat Exchanger 220 connects with oil-gas transportation pump 210, and the second heat exchanger 230 is with described First Heat Exchanger 220 even
Logical, the second heat exchanger 230 connects with described 3rd heat exchanger 240, and the tower tray and the 3rd heat exchanger 240 that are positioned at highest point connect.
Chiller 300 includes cooling heat exchanger 310, air cooler 320 and water cooler 330, be positioned at highest point tower tray,
Cooling heat exchanger 310, air cooler 320, water cooler 330 and products pot 400 are sequentially communicated.
The operation principle of this crude(oil)unit and process are such that oil gas and extract out from the inner chamber of atmospheric tower 100, so
After be returned directly to, in atmospheric tower 100 in the tower tray of highest point, flow out from this tower tray the most again, depend on after often top heat exchanger cooling
Secondary after the cooling of cooling heat exchanger 310, air cooler 320 and water cooler 330, enter in products pot 400.Last at product
Under acid water centrifugation in tank 400, it is thus achieved that Petroleum also flows out products pot 400.
Above-mentioned air cooler 320 can be to use various structures and form, and with reference to Fig. 2, in the present embodiment, air cooler 320 includes
Influent stream pipe 321, cooling tube 322 and outflow tube 324, influent stream pipe 321 and the spaced and parallel setting of outflow tube 324.Cooling tube 322
Two ends connect with influent stream pipe 321 and outflow tube 324 respectively, and cooling tube 322 has many and along influent stream pipe 321 or outflow tube 324
Length direction interval arrange.Every cooling tube 322 is provided with multiple gas channel being parallel to each other in cuboid and in it,
Multiple gas channels are spaced setting along the width of cooling tube 322.So arrange and can increase connecing of oil gas and cooling tube 322
Contacting surface is amassed, thus improves cooling effect.
Further, between adjacent two cooling tubes 322, it is provided with corrugated fin 323, fin 323 length direction
Both sides connect with the outer wall of two adjacent cooling tubes 322 respectively.Arrange the purpose of fin 323 be to increase cooling tube 322 with
The contact area of surrounding air, thus it is effectively improved the cooling effectiveness of air cooler 320.
The operation principle of this air cooler 320 and process are such that high-temperature oil gas and enter influent stream pipe 321, are then passed through many
After root cooling tube 322, arriving outflow tube 324 and flow out, during cooling tube 322, the heat of high-temperature oil gas can lead to
Supercooling pipe 322 and fin 323 are delivered in the air of surrounding, thus constantly scatter and disappear, it is achieved cool effect.
Above-mentioned water cooler 330 can be to use various structures and form, and with reference to Fig. 3, in the present embodiment, water cooler 330 includes
Inlet tube 331, outlet 333 and heat exchange tank 332, be provided with the first baffle plate 334 and second baffle 335 in heat exchange tank 332, the
The inner chamber of heat exchange tank 332 is cut off for entrance cavity, heat exchanging chamber and outlet plenum by one baffle plate 334 and second baffle 335, entrance cavity with
Inlet tube 331 connects, and outlet plenum connects with outlet 333.
Being provided with many heat exchanger tubes 336 in heat exchanging chamber, the two ends of every heat exchanger tube 336 connect with entrance cavity and outlet plenum respectively
Logical, and many heat exchanger tubes 336 are the most in the shape of a spiral, use spiral helicine purpose to be the contact area increasing heat exchanger tube 336 with water,
Thus improve the heat exchange cooling effect to high-temperature oil gas.Water inlet and outlet it is additionally provided with, water inlet and going out on heat exchange tank 332
The mouth of a river connects with heat exchanging chamber respectively.
Further, water cooler 330 also includes water-circulating cooling device, and water-circulating cooling device includes the first valve, circulation pipe
337 and second valve, the first valve is selected stop valve and is arranged on outlet 333, and circulation pipe 337 is U-shaped, the two of its opening
In end, one end is communicated on outlet 333 and connectivity part is between the first valve and heat exchange tank 332, and the other end is communicated in entrance
On pipe 331, the second valve is also selected stop valve and is arranged on circulation pipe 337.
First the operation principle of this water cooler 330 and process are such that, and cooling water enters heat exchanging chamber by water inlet,
Flow out from outlet pipe after filling heat exchanging chamber.Then, high-temperature oil gas enters in entrance cavity by inlet tube 331, the most again through too much
After root heat exchanger tube 336, reach in outlet plenum, finally flow out from outlet 333.In high-temperature oil gas through too much root heat exchanger tube 336
During, the heat in high-temperature oil gas can pass to the cooling water in heat exchanging chamber by heat exchanger tube 336, thus realizes cooling
Effect.
Finally, if needing circulation repeatedly oil gas to be cooled, can be realized by water-circulating cooling device.Specifically
Ground, closes the first valve on outlet 333, opens the second valve on circulation pipe 337, enters outlet through overcooled oil gas
After pipe 333, owing to the first valve is closed, therefore will enter in circulation pipe 337, thus along circulation pipe 337 weight
Newly return in inlet tube 331, back flow back into heat exchange tank 332 and again cool down.This apparatus structure is simple, easy to operate, permissible
Effectively realize the circulating cooling of oil gas.
The crude(oil)unit that the embodiment of the present invention provides has the advantages that
1, the cryogenic effect that cold reflux causes is avoided: time in cold reflux return tower, local temperature in distillation column can be caused
Too low region, causes serious salt acid dew piont corrosion.Eliminate cold reflux in the present invention, do not have local temperature point mistake
Low area, thus the corrosion avoiding this type of occurs.
2, the corrosive substance in tower is reduced: when having backflow, oil product can carry corrosive substance and return to, in tower, cause
Anticaustic.After cancelling cold reflux, the corrosive substance in tower reduces, and slow down hydrogen-chloride etching and the generation of ammonium salt fouling.
3, avoid the underdeposit corrosion caused during water revaporization: water once generates, will together with hydro carbons in tower to dirty
Dynamic, water enters higher temperature province, and by revaporization, the concentration of corrosivity solute improves, after water completely vaporizes, stays and may draw
Play the solid precipitation of underdeposit corrosion.Eliminate cold reflux in the present invention, do not have the generation of water, also avoid this type
Corrosion.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For Yuan, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made,
Equivalent, improvement etc., should be included within the scope of the present invention.
