Description
Technical field
The present invention relates to crude oil purification equipment technical field, especially a kind of spiral heat exchanger eddy current, centrifugal sediment outflow interface arrangement.
Background technology
Spiral heat exchanger, because heat exchange efficiency is high, has self-cleaning function after passage fouling, and the preheating conveying etc. that is widely used in crude oil is easily in fouling medium technique. But owing to containing a large amount of silt particles in crude oil, and the instability of flow of crude oil, when flow velocity is less than in the situation of 1m/s or intermitten service, silt particle in crude oil easily deposits in the passage of heat exchanger, result in blockage, have a strong impact on the normal operation of heat exchanger, cause very large difficulty to operation maintenance, heat exchanger tends to therefore reduce 50% service life.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, spiral heat exchanger eddy current, centrifugal sediment outflow interface arrangement are proposed, by the design to the each structure in spiral heat exchanger below, effectively realize separating of crude oil and silt, avoid oil-sand greasy filth to accumulate in spiral heat exchanger and result in blockage.
In order to realize foregoing invention object, the invention provides following technical scheme:
Spiral heat exchanger eddy current, centrifugal sediment outflow interface arrangement, comprise crude oil import adapter, eddy current drainage cylindrical shell, crude oil gathering sill, taper sediment outflow cylindrical shell and sewage draining exit,
Described eddy current drainage cylindrical shell is arranged on spiral heat exchanger bottom and is connected with described spiral heat exchanger lower surface outmost turns crude oil side open channels,
Described taper sediment outflow cylindrical shell is arranged on described eddy current drainage cylindrical shell bottom,
Described crude oil gathering sill is arranged in described eddy current drainage cylindrical shell, is close to described eddy current drainage cylinder inboard wall and extends spirally, and described crude oil gathering sill lowermost end is taken over and is connected with the crude oil import that stretches out described eddy current drainage cylindrical shell,
Described sewage outfalls setting is in described taper sediment outflow cylindrical shell bottom.
Further, at described crude oil gathering sill end face, be evenly distributed with some oil outlets along described crude oil gathering sill length direction,
In described crude oil gathering sill bottom surface, be evenly distributed with some sand discharges hole along described crude oil gathering sill length direction.
Further, described crude oil import is taken over and is connected with described crude oil gathering sill with described eddy current drainage cylindrical shell cross section tangential direction.

Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
Spiral heat exchanger eddy current as shown in Figures 1 to 4, centrifugal sediment outflow interface arrangement, comprise crude oil import adapter 1, eddy current drainage cylindrical shell 2, crude oil gathering sill 3, taper sediment outflow cylindrical shell 4 and sewage draining exit 5, and sewage draining exit 5 is removable,
Eddy current drainage cylindrical shell 2 is arranged on spiral heat exchanger 6 bottoms and is connected with spiral heat exchanger 6 lower surface outmost turns crude oil side open channels,
Taper sediment outflow cylindrical shell 4 is arranged on eddy current drainage cylindrical shell 2 bottoms,
Crude oil gathering sill 3 is arranged in eddy current drainage cylindrical shell 2, is close to eddy current drainage cylindrical shell 2 spiral inner walls and extends, and crude oil gathering sill 3 lowermost ends are taken over 1 with the crude oil import that stretches out eddy current drainage cylindrical shell 2 and are connected,
Taper sediment outflow cylindrical shell 4 is for being inverted shape cylinder cone, and sewage draining exit 5 is arranged on taper sediment outflow cylindrical shell 4 bottoms.
Crude oil gathering sill 3 cross sections are square, at its end face, be evenly distributed with some oil outlets 31 along crude oil gathering sill 3 length directions,
In crude oil gathering sill 3 bottom surfaces, be evenly distributed with some sand discharges hole 32 along crude oil gathering sill 3 length directions.
In the present embodiment, oil outlet 31 and sand discharge hole 32 diameters all arrange one around each 15 degree of eddy current drainage cylindrical shell 2 axis.
Crude oil import is taken over 1 and is connected with crude oil gathering sill 3 with eddy current drainage cylindrical shell 2 cross section tangential directions.
Crude oil gathering sill 3 from its lowermost end to become 5 degree inclination angles upwards to extend spirally with horizontal plane.
When use, crude oil is taken over 1 from crude oil import and is entered eddy current drainage cylindrical shell 2, is being directed at the interior formation spiral vortex of eddy current drainage cylindrical shell 2 by crude oil gathering sill 3. Under the effect of centrifugal force, the solids of heavy sand grains drops in taper sediment outflow cylindrical shell 4. Crude oil after desanding enters in spiral heat exchanger 6, after heat exchange, discharges. Taper sediment outflow cylindrical shell 4 can be by dismountable sewage draining exit 5 periodic cleanings.
Spiral heat exchanger eddy current of the present invention, centrifugal sediment outflow interface arrangement, by the design to the each structure in spiral heat exchanger below, effectively realized separating of crude oil and silt, avoids oil-sand greasy filth to accumulate in spiral heat exchanger and result in blockage.
