Description
(1) technical field
The utility model relates to a kind of OIL IN LUBRICATING OIL PRODUCTION equipment, particularly relates to a kind of dewaxing separation equipment for lubricating oil.
(2) background technology
At present, when producing lubricating oil, need to dewax and make lubricating oil under cryogenic conditions, keep good mobility the thick oil product of lubricating oil, the thick oil product of producing need to carry out removing wax in blowpit.Yet have a small amount of oil product along with gas wax leaves blowpit in the process of dewaxing, in order to prevent entering oil product in wax gathering system, on blowpit top, knockout drum can be installed, after gas-liquid separation, gas phase enters gassy system by knockout drum top, and the liquid phase pipeline that liquid phase is connected with blowpit by knockout drum bottom is back in blowpit.Yet in now general blowpit separated device, when lubricating oil oil product steams gas wax in blowpit, the liquid phase pipeline that gas is easy to reflux by oil product enters in separator, cause liquid phase systems punching slurry foamed phenomenon, reduce dewaxing efficiency, the part oil product difficult consequence that refluxes, waste product, reduces productive rate.Therefore be necessary existing OIL IN LUBRICATING OIL PRODUCTION equipment to improve, can effectively avoid the gas in blowpit to enter knockout drum by oil product reflux pipeline, stop the phenomenon of liquid phase systems punching slurry foaming, guaranteed the pressure differential of knockout drum and blowpit, thereby dewaxing efficiency is improved, oil product refluxes more smooth and easy, reaches the object that reduces product waste.
(3) utility model content
In order to overcome the weak point of existing OIL IN LUBRICATING OIL PRODUCTION equipment, the utility model provides a kind of dewaxing separation equipment for lubricating oil.
The technical solution of the utility model is to realize like this.
A kind of dewaxing separation equipment for lubricating oil of this programme, comprises blowpit and knockout drum, and described blowpit one side is provided with charging aperture, on the blowpit opposite side relative with this charging aperture, is provided with discharging opening; Described blowpit end face is provided with oil product refluxing opening; On described blowpit end face, be provided with exhaust outlet; Described gas-liquid separation upper end is provided with gas outlet; Described knockout drum bottom is provided with discharging opening; Described knockout drum side wall upper part is provided with feeding mouth; The exhaust outlet of described blowpit and the feeding mouth of knockout drum pass through pipeline communication; The oil product refluxing opening of described blowpit one side is communicated with by reflux line with the discharging opening of knockout drum bottom, and this reflux line is U-shaped; Described blowpit bottom is provided with heater.
Described reflux line and oil product refluxing opening connectivity part are a little less than the connectivity part with discharging opening.
Usefulness of the present utility model is: this device structure is simple, easy to use, can effectively avoid the gas in blowpit by oil product reflux pipeline, to enter the generation of the phenomenon of knockout drum, stop the phenomenon of liquid phase systems punching slurry foaming, guaranteed the pressure differential of knockout drum and blowpit, thereby it is more smooth and easy that dewaxing efficiency raising, oil product are refluxed, and improves paraffin yield, avoid product waste, improved product yield.
(4) accompanying drawing explanation
Fig. 1 is institutional framework schematic diagram of the present utility model.
(5) specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is made to brief description.
A kind of dewaxing separation equipment for lubricating oil as figure, comprises blowpit 1 and knockout drum 5, and described blowpit 1 one sides are provided with charging aperture 2, on blowpit 1 opposite side relative with this charging aperture 2, is provided with discharging opening 12; Described blowpit 1 end face is provided with oil product refluxing opening 4; On described blowpit 1 end face, be provided with exhaust outlet 3; Described knockout drum 5 tops are provided with gas outlet 10; Described knockout drum 5 bottoms are provided with discharging opening 6; Described knockout drum 5 side wall upper part are provided with feeding mouth 7; The exhaust outlet 3 of described blowpit 1 is communicated with by pipeline 8 with the feeding mouth 7 of knockout drum 5; The oil product refluxing opening 4 of described blowpit one side is communicated with by reflux line 9 with the discharging opening 6 of knockout drum 5 bottoms, and this reflux line 9 is U-shaped; Described blowpit 1 bottom is provided with heater 11.
Described reflux line 9 and oil product refluxing opening 4 connectivity parts are a little less than the connectivity part with discharging opening 6.
The course of work of this example: while using this equipment to be lubricated paraffin in the thick oil product of oil to remove, first the thick oil product of the lubricating oil of producing is poured in blowpit 1 from charging aperture 2, heater 11, make paraffin become gas removes from oil product, in the gas that removes out due to paraffin, can carry a small amount of oil product, in order to prevent that oil product drop from entering gas phase and discharging, cause the waste of product, therefore the butadiene gas that removes is out entered to knockout drum 5 inside by pipeline 8 by feeding mouth 7 from exhaust outlet 3 carries out gas-liquid separation, paraffin gas after separation is discharged and is collected from the gas outlet 10 at knockout drum 5 tops, and collecting in knockout drum 5 bottoms, the oil product drop of separating through reflux line 9, from oil product refluxing opening 4, is back to blowpit 1 inside from discharging opening 6, in order to prevent that paraffin gas in blowpit 1 from entering liquid phase systems from reflux line 9 and causing the foaming of liquid phase punching slurry, therefore reflux line 9 is arranged to U-shaped pipe, and reflux line 9 and oil product refluxing opening 4 connectivity parts are a little less than the connectivity part with discharging opening 6, oil product hydraulic coupling while making to reflux is greater than the interior paraffin gas pressure of blowpit 1, reach the effect of fluid-tight, thereby make paraffin gas enter the liquid phase systems in knockout drum 5 by reflux line 9, avoid causing the foaming of liquid phase punching slurry.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
