Background technology：
With the development of economy, the application of lubricating oil is increasingly extensive, lubricating oil in use for some time, performance indicator
Decline and need replacing, to generate a large amount of waste.Since waste lubricating oil is after refined and modifying process, additionally it is possible to
Recycling, therefore more and more important has been become to waste lubricating oil recovery and reusing and recycling, it both economized on resources, turned waste into wealth, again
It can reduce and prevent the pollution of the environment, there is very considerable economic benefit and social benefit.
Currently, China's process for regeneration of waste lubricating oil, still in relatively primitive state, traditional processing technology routine also takes up
Leading position, and traditional waste lubricating oil recycles mixed hydrogenation treatment process, complex steps, the waste of generation be more, oneself
The low, poor quality of properties of product etc. that dynamicization degree is low, produces.
Utility model content：
The utility model in order to make up for the deficiencies of the prior art, provide it is a kind of for waste lubricant oil regeneration plus hydrogen dress
It sets, is especially suitable for processing waste lubricating oil material inferior, it can be can only be handled refined as the waste that fuel uses originally
It by re-effective is utilized for the high raw material of lubricating oil oil product, advantageously reduces pollution, the renewable cycle of the energy is promoted to make
With solving problems of the prior art.
Used technical solution is the utility model to solve above-mentioned technical problem：
A kind of hydrogenation plant for waste lubricant oil regeneration is mainly made of separator, reactor and fractionating column, is being detached
Device is equipped with waste lubricating oil oil inlet and auxiliary agent adding mouth, in oil product component into catalyst is added before reactor, in reactor
Bottom is equipped with blow-off pipe；Hydrogen inlet is equipped on reactor；It is equipped with naphtha collector at the top of fractionating column, is being fractionated
The middle part of tower is equipped with diesel oil collector, is equipped with lube cut oil interceptor in the lower part of fractionating column, is set in the bottom of fractionating column
There is heavy component collector.
The separator is hypergravity separator.
The reactor is impact flow reactor.
The catalyst is to contain the two or more mixtures in molybdenum, cobalt, iron, zinc, copper.
The auxiliary agent is the mixture of demulsifier and flocculant.
The mode that the utility model reactor is fed respectively using liquid, gas reaches the feedstock oil of certain temperature
Enter from the lower part of reactor after mixed catalyst, is sprayed upwards by raw material nozzle component；Hydrogen enters the middle part of reactor
Nozzle assembly flows downward, and the feedstock oil counter current contacting from reactor lower part, and reacts.Counter current contacting can be strengthened
The mass transfer of gas and two kinds of materials of liquid expands contact area, achievees the purpose that fast reaction；Lower reactor is empty simultaneously
Speed, also helps the sundries such as the metal in raw material, colloid, asphalitine and the catalyst for refining reaction slowly concentrates on instead
The bottom for answering device is provided with oil circulating pump, the cycle stock nozzle in the middle part of Returning reactor in reactor bottom.From entirety, remove
Reactor top is provided with outside the gas-phase space of certain altitude, and rest part is in liquid phase state, makes the temperature in reactor
It is substantially balanced, it not will produce the high phenomenon of local temperature, so, percussion flow hydrogenation reactor is not easy green coke, tailings discharge
The advantages that amount waits less, distillate yield is up to 85% or more, also has superior product quality, automatic controlling level height etc. excellent
Point has wide popularizing application prospect.

Specific implementation mode：
In order to clarify the technical characteristics of the invention, below by specific implementation mode, and its attached drawing is combined, to this reality
It is described in detail with novel.
As shown in Figure 1, a kind of hydrogenation plant for waste lubricant oil regeneration, mainly by separator 1, reactor 2 and fractionation
Tower 3 forms, and waste lubricating oil oil inlet 4 and auxiliary agent adding mouth 5 are equipped on separator 1, in oil product component into being added before reactor 2
Catalyst 12 is equipped with blow-off pipe 6 in the bottom of reactor 2；Hydrogen inlet 7 is equipped on reactor 2；On the top of fractionating column 3
Portion is equipped with naphtha collector 8, and diesel oil collector 9 is equipped at the middle part of fractionating column 3, and lubricating oil is equipped in the lower part of fractionating column 3
Fraction oil interceptor 10 is equipped with heavy component collector 11 in the bottom of fractionating column 3.
The separator 1 is hypergravity separator 1；The moisture content in waste lubricating oil is taken off using mechanical means by density contrast
It removes, obtains relatively pure oil product component, while the ingredients such as part metals, impurity can also be removed.
The reactor 2 is impact flow reactor 2；Under the effect of the catalyst with hydrogen counter current contacting, carries out plus hydrogen is smart
System reaction, and remove demetalization, Jiao Zhi, asphalitine and a variety of harmful components again.
The catalyst 12 is to contain the two or more mixtures in molybdenum, cobalt, iron, zinc, copper.
The auxiliary agent is the mixture of demulsifier and flocculant.
When operation, the heavy ingredients such as raw material is tangentially sent into the internal layer of hypergravity separator 1 by high speed, and moisture, machine are miscellaneous by
It gradually flows downward, oil product component flows upwards out, and percussion flow hydrogenation reactor 2 is removed after heating.The method handle detached by hypergravity
Moisture content removing is fallen in waste lubricating oil, obtains relatively pure oil product component, at the same also remove part metals, mechanical admixture etc. at
Point；By oil product component under the effect of the catalyst enter percussion flow hydrogenation reactor 2, carry out hydrofining reaction, removing metal,
The a variety of harmful components of Jiao Zhi, asphalitine etc.；Reaction product enters separator 1, and gas-liquid separation is carried out by high score, separation
Gas is used for hydrogenation reaction as recycle hydrogen, and isolated liquid enters fractionating column 3 and detached；It is obtained at 3 top of fractionating column
To naphtha, 3 middle part side line of fractionating column obtains diesel component, and 3 lower part side line of fractionating column obtains lube cut, and tower bottom obtains
Heavy component；The heavy component of 3 bottom of fractionating column comes back for freshening operation, can also be as byproduct.
