Background technique
Need to isolate distillate, common steaming using vacuum tower in waste mineral oil reclaimed lubricating oil base oil production process
Evaporating column distillation process is: the waste mineral oil of heating enters in tower from the middle and lower part of vacuum distillation tower, and gas phase rises from tower, is filling out
The bed of material completes heat transfer, mass transfer, produces after being collected by collecting tank, and uncooled incoagulable gas is exported from top gaseous phase and escaped；300
DEG C or so high temperature distillation raffinate from tower bottom produce, after condenser is cooled to 80~100 DEG C be sent into storage tank storage, Huo Zheyong
Heat exchanger takes the heat of vinasse to be utilized.
Vinasse temperature is relatively high, is not used, i.e. increase thermal energy consumption, and consumes cooling water.And heat utilization
When want the equipment such as mating setting delivery pump, pans, increase investment and kinetic energy consumption.
Summary of the invention
The utility model aim be the defect for existing destilling tower provide it is a kind of it is compact-sized, energy saving, with low investment,
The high integral type heat recovery destilling tower of the thermal efficiency.
The utility model to achieve the above object, adopts the following technical scheme that
The top gaseous phase outlet at the top of the tower body is arranged in a kind of integral type heat recovery destilling tower, including tower body,
Be characterized in that: the tower body middle and lower part is provided with material inlet, is provided with collecting tank above material inlet；The material inlet and
There is level-one filler between collecting tank；The tower body lower part is provided with heat-exchanger rig and vinasse outlet.
It is more heat pipes it is further characterized by: the heat-exchanger rig, locating for the bringing-up section and heat release section of the heat pipe
Tower body it is mutually isolated；Cold medium import and thermal medium outlet are respectively arranged on tower body locating for the heat release section.
Further: the bringing-up section of the heat pipe is light pipe, is provided with fin in the heat release section of the heat pipe.
The cold medium import is located at the tower body bottom, and the thermal medium outlet is located at tower body locating for the heat release section
Upper portion side wall.
It is preferred: there is overhead reflux import, the overhead reflux import and overhead reflux distributor at the top of the tower body
It is connected；Second level filler is provided with below the overhead reflux distributor.
Washing liquid distributor is provided between the collecting tank and level-one filler.
Directly heat-exchanger rig is arranged in tower body lower part in the utility model, and the thermal energy of high temperature distillation raffinate is effectively utilized,
While thermal energy recycling, additional equipment is not needed.The utility model is compact-sized, while saving energy, saves throwing
Money, the thermal efficiency are high.It is particularly suitable for waste mineral oil reclaimed lubricating oil base oil production process.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Specific embodiment
As shown in Figure 1, a kind of integral type heat recovery destilling tower, including tower body 1, the tower overhead gas at 1 top of tower body is set
Mutually outlet 2.1 top of tower body also has overhead reflux import 3, and overhead reflux import 3 is connected with overhead reflux distributor 4.Tower top
Second level filler 5 is provided with below backflow distributor 4.1 middle and lower part of tower body is provided with material inlet 6, is provided with above material inlet 6
Collecting tank 7；There is level-one filler 8 between material inlet 6 and collecting tank 7；Washing is provided between collecting tank 7 and level-one filler 8
Liquid distributor 9.1 lower part of tower body is provided with more heat pipes 11 and vinasse outlet 10.Bringing-up section and the heat release section institute of heat pipe 11
The tower body 1 at place is mutually isolated；1 upper bottom portion of tower body locating for heat release section is provided with cold medium import 13, and upper portion side wall is provided with heat
Media outlet 12.To guarantee heat-transfer effect, preventing vinasse from depositing on 11 surface of heat pipe, the bringing-up section of heat pipe 11 is light pipe,
Fin is provided in heat release section.
When utility model works, the waste mineral oil after heating enters tower body 1 from material inlet 6, and gas phase rises from tower,
Heat transfer, mass transfer are completed in level-one filler 8, is produced after being collected by collecting tank 7, uncooled incoagulable gas is exported from top gaseous phase
2 evolutions.Distillate after collecting tank 7 is collected flows back by overhead reflux import 3 and overhead reflux distributor 4, flows through two
Grade filler 5 carries out distilation again.High temperature distillation raffinate heats the working medium of bringing-up section in heat pipe 11, and working medium is put in heat release section again
Medium outside heat heat pipe 11 out, is utilized the heat of vinasse.And wash liquid distributor 9 then can be by adding
Enter cleaning solution, to following packing layer cloth liquid, washs filler.
Since heat pipe is a kind of high-performance heat transfer components, there is the laudatory title of " heat energy superconductive body ", since it is to utilize substance (liquid
Body) phase transformation and steam flowing carry out heat transfer, its heat transfer efficiency be most excellent heat-conducting metal (silver, lithium, copper) when
Thousands of times for measuring thermal conductivity, with the capacity of heat transmission is big, average temperature performance is excellent, heat flow density is adjustable, to the adaptation energy of thermal source environment
The extremely strong equal remarkable advantages of power.Therefore, the integral type destilling tower using heat pipe as heat-exchange device, have it is compact-sized, energy saving,
With low investment, the advantages that thermal efficiency is high.
