Abstract
The utility model discloses a waste lubricating oil combined engler distillation device which comprises an engler distillation primary distillation tower, an engler distillation heating furnace, an engler distillation kettle and an engler distillation fractional distillation tower, wherein the engler distillation kettle comprises a first engler distillation kettle and a second engler distillation kettle which are both not provided with fractional distillation segments; and upper parts of the first engler distillation kettle and the second engler distillation kettle are connected with the engler distillation fractional distillation tower through pipe lines. By adopting the waste lubricating oil combined engler distillation device with the structure, when the distillation waste lubricating oil of the waste lubricating oil combined engler distillation device is used, the original interrupted-type distillation in the distillation kettle is converted into continuous distillation in the engler distillation fractional distillation tower, thus not only production efficiency of the device is improved, but also the amplitude and frequency times of device operation vibration are reduced, and the device running energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of water distilling apparatus that is used for waste lubricant oil regeneration, especially relates to a kind of waste lubricating oil associating Engler distillation device.
Background technology
Lubricating oil in use receives influence and the aged deterioration gradually of environment for use usually, after lubricating oil uses certain hour, is to guarantee mechanical movement, carries out periodic oil change, and this has just produced a large amount of waste lubricating oils.The waste lubricating oil of these recovery is mixtures of various different sorts lubricating oil; And contain imperfect components such as certain moisture content, iron filings, additive (lubricating oil needs to add various additives according to different purposes usually, and these additives generally are to contain elements such as heavy metal, sulphur), acidic substance, greasy filth.
At present, some adopts distillation-furfural treatment-sulfuric acid clay finishing technology domestic waste lubricant oil regeneration, and its distillation has employing to be interrupted suitching type Engler distillation (decompression) technology.Engler distillation device of the prior art comprises Engler distillation primary tower, Engler distillation process furnace and Engler distillation still; The oil-in of said Engler distillation primary tower is connected with the Engler distillation feed exchanger; Be connected with between Engler distillation primary tower and the Engler distillation process furnace and be used for the fore-running column bottoms pump that boosts oil at the bottom of the primary tower to be delivered to engler's process furnace; The oil outlet of said Engler distillation process furnace links to each other with the oil-in of Engler distillation still through pipeline; The oil return opening of Engler distillation still links to each other with the oil-in of said Engler distillation process furnace through the still recycle pump, and the top of Engler distillation still has the fractionation section.When the Engler distillation device of said structure moves; After the waste lubricating oil distillation finishes in the Engler distillation still; Residual oil pump at the bottom of still moves back oil, heat exchange, the laggard Residual Oil Tank of cooling at the bottom of the still; Again charge of oil, heat exchange, distillation more afterwards, the problem one that such discontinuous Engler distillation device exists when the distillation waste lubricating oil is that production efficiency is low, the 2nd, the operation fluctuation is frequent, the device operation energy consumption is high.
The utility model content
The technical problem that the utility model will solve provides a kind of production efficiency height, can reduce the amplitude of device operation fluctuation and the waste lubricating oil associating Engler distillation device that the frequency also can reduce the device operation energy consumption.
For solving the problems of the technologies described above; A kind of waste lubricating oil associating of the utility model Engler distillation device; Comprise Engler distillation primary tower, Engler distillation process furnace and Engler distillation still; The oil-in of said Engler distillation primary tower is connected with the Engler distillation feed exchanger; Be connected with between Engler distillation primary tower and the Engler distillation process furnace and be used for the fore-running column bottoms pump that boosts oil at the bottom of the primary tower to be delivered to engler's process furnace; The oil outlet of said Engler distillation process furnace links to each other with the oil-in of Engler distillation still through pipeline, and the oil return opening of Engler distillation still links to each other with the oil-in of said Engler distillation process furnace through the still recycle pump, and the residual oil outlet of Engler distillation still links to each other with Residual Oil Tank through pump at the bottom of the still; Said Engler distillation still comprises the first Engler distillation still and the second Engler distillation still, and the first Engler distillation still and the second Engler distillation still all do not have the fractionation section; Said waste lubricating oil associating Engler distillation device also has an Engler distillation separation column, and the top of the said first Engler distillation still and the second Engler distillation still links to each other with this Engler distillation separation column through pipeline.
Adopt the waste lubricating oil associating Engler distillation device of said structure, because the first Engler distillation still and the second Engler distillation still all do not have the fractionation section; Said waste lubricating oil associating Engler distillation device also has an Engler distillation separation column; The top of the said first Engler distillation still and the second Engler distillation still links to each other with this Engler distillation separation column through pipeline; Therefore; When using this waste lubricating oil associating Engler distillation device distillation waste lubricating oil; Change the original batch distillation in a still kettle in the Engler distillation separation column continuous fractionation, so not only improved the production efficiency of device but also reduced the amplitude and the frequency of device operation fluctuation and reduced the device operation energy consumption.
