Pump 3c, quantitative refueling pump the 14, first vacuum pump set 8b, the second vacuum pump set 11b takes a preparation and a use.
It is specific below to illustrate that the waste oil disposal flow of tower waste oil processing equipment in the lower present invention is：
Raw material waste oil 15 is pumped into the waste oil reactor 1a of waste oil preprocessing module 1 by oil-feed pump 16 from waste oil oil inlet
In, and so that raw material waste oil 15 is fully reacted with additive by agitator 1b.Waste oil after waste oil pre-processes,
Pretreated waste oil is pumped into fuel oil distillation module 2 by oil outlet pump 17 and is distilled.Waste oil distills mould in fuel oil
Two parts product can be obtained after being distilled in block 2, a part of product is light Fuel oil vapour and middle matter fuel oil vapour, another portion
It is divided into the distillating material (useless feed of base oil) that base oil distillation module 3 provides.
When the tower temperature that fuel oil distills module 2 reaches 55~110 DEG C, the product distilled is that light-weight fuel oil steams
Vapour, gained light Fuel oil vapour in two concatenated light Fuel oil cooler 4a in the first refrigerating module 4 by carrying out
After being fully cooled, light-weight fuel oil raw material and non-condensable gas are obtained.When light-weight fuel oil raw material and non-condensable gas enter
After in first collection module 7, light-weight fuel oil raw material and non-condensable gas are separated by the first light-weight fuel oil converter 7a,
Light-weight fuel oil raw material is alternately entered respectively into the first oil interceptor 7b and 7c, is divided by the first light-weight fuel oil converter 7a
Non-condensable gas from after is entered back into the first vacuum module 8.Lightweight combustion after the first oil interceptor 7b and 7c is collected
Material oil, which is pumped into through oil pump (unmarked) in the first mixer 7d, to be thoroughly mixed, and light-weight fuel oil finished product 18 is obtained.
Certainly first filter (not shown) can be arranged after the first mixer 7d in different embodiments to be filtered.
When the tower temperature that fuel oil distills module 2 reaches 110~220 DEG C, the product distilled is that middle matter fuel oil steams
Vapour, matter fuel oil vapour is filled by three concatenated middle matter fuel oil cooler 4b in the first refrigerating module 4 in gained
After dividing cooling, middle matter fuel oil raw material and non-condensable gas are obtained.Matter fuel oil raw material and non-condensable gas enter in the middle
After in two collection modules 6, middle matter fuel oil raw material and non-condensable gas are separated by matter fuel oil converter 6a in second, in
Matter fuel oil raw material is alternately entered respectively into the second oil interceptor 6b and 6c, after matter fuel oil converter 6a separation in second
Non-condensable gas enter in the first vacuum module 8.Middle matter fuel oil after oil interceptor 6b and 6c are collected is through oil pump
(unmarked) is pumped into the second mixer 6d and is thoroughly mixed.Mixed middle matter fuel oil passes through another oil pump
(unmarked) is pumped into the second filter 6e and is filtered, you can obtains middle matter fuel oil product 19.
Entered by the non-condensable gas that matter fuel oil converter 6a is separated in the first light-weight fuel oil converter 7a and second
After first vacuum module 8, the first tail is entered by Vacuum converters 8a, vacuum pump set 8b and sealed high-pressure suction fan 8d
In first water seal 9a of gas disposal module 9.Tail gas after treatment is further sent to fuel by its first air-introduced machine 9b
In oil distillation module 2, tail gas can be to the fuel oil cloth in fuel oil destilling tower 2b after the 2a heating of fuel oil tube heater
Device 2d and fuel oil filler material 2e are heated, and prevent fluid in its surface coking, block the fuel oil distributing device 2d and fuel
Oily filler material 2e.
The useless feed of base oil of product of fuel oil distillation module 2 is pumped into base by low temperature oil pump 2c and quantitative refueling pump 14
Plinth oil distills in module 3.Herein, to prevent the coking in base oil distills pipeline and the pump housing in module 3 of useless feed of base oil,
It needs first to open electric-heating heat-conductive oil case 3f and the conduction oil in fuel tank is heated, and will be heated by heat conduction oil circulating pump 3g
Conduction oil afterwards is pumped into high temperature oil pump insulation jacket 3h and pipe insulation chuck 3i, to corresponding high temperature pump housing 3c and its pipe
It is heated in road.
When the tower temperature that base oil distills module 3 reaches 220~360 DEG C, the product distilled is basic oil vapour, institute
Basic oil vapour is obtained after the concatenated basis oil cooler 5a of three in the second refrigerating module 5 is fully cooled, is obtained
Feed of base oil and non-condensable gas.After feed of base oil and non-condensable gas enter in third collection module 7, by
Three base oil converter 10a separate feed of base oil and non-condensable gas, and feed of base oil alternately enters the collection of third oil
In device 10b and 10c, the non-condensable gas after the 10a separation of third base oil converter enters in the second vacuum module 11.Through
It crosses the base oil after third oil interceptor 10b and 10c are collected and is pumped into third mixer 10d through oil pump (unmarked) and filled
Divide mixing.Mixed base oil is pumped into third filter 10e by another oil pump (unmarked) and is filtered, you can
To base oil finished product 20.After entering the second vacuum module 11 by the non-condensable gas that third base oil converter 10a is separated, pass through
Second Vacuum converters 11a, the second vacuum pump set 11b and sealed high-pressure suction fan 11d enter the second vent gas treatment mould
In second water seal 12a of block 12.Tail gas after treatment is further sent to base oil by the second air-introduced machine 12b and distills mould
In block 3, generated heat can be in base oil destilling tower 3b after base oil tube heater 3a fully burn for tail gas
Base oil distributing device 3d and base oil filler material 3e heated, prevent fluid in its surface coking, block the basis oilcloth
Glassware 3d and base oil filler material 3e.
It is exactly that waste oil preprocessing module 1 is steamed through fuel oil again after mixing raw material waste oil 15 with additive for simple
Evaporate module 2 distilled obtained by a part of light Fuel oil vapour and middle matter fuel oil vapour enter the first refrigerating module 4 into
Row is cooling and another part distillating material carried out again through base oil distillation module 3 the basic oil vapour of distillation gained again into
Enter the second refrigerating module 5 to be cooled down；First refrigerating module 4 is cooled down the light-weight fuel oil raw material of gained by the first collection module 7
Light-weight fuel oil finished product 18 is detached and collected out with non-condensable gas, and the second collection module 6 cools down the first refrigerating module 4
The middle matter fuel oil raw material and non-condensable gas of gained are detached and collect out middle matter fuel oil product 19, third collection module
The feed of base oil of second refrigerating module 5 cooling gained and non-condensable gas are detached and collect out base oil finished product by 10
20；The non-condensable gas that first vacuum module 8 isolates the first collection module 7 and the second collection module 6 carries out vacuum cycle
Fuel oil being sent into through the first vent gas treatment module 9 again after processing and distilling module 2, the second vacuum module 11 is by third collection module 10
The non-condensable gas isolated is sent into base oil distillation module through the second vent gas treatment module 12 again after carrying out vacuum cycle processing
3, it can not only achieve the purpose that the energy makes full use of, and can also be achieved the closed-loop process of waste oil in this way.
Finally illustrate, the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to compared with
Good embodiment describes the invention in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the present invention
