Description
Technical field
The utility model relates to the vacuum distillation apparatus of organic materials, particularly condensation diversion reduced pressure distiller in a kind of tank.
Background technology
Decompression distillation is a kind of distillating method of realizing reducing the energy-conservation of feed liquid boiling temperature and suppressing to distill the feed liquid pyrolysis by reducing air pressure, be widely used at present, but the degree of the energy saving of decompression distillation and the pyrolysis of inhibition distillation feed liquid is current distillation those skilled in the art's focus.
A kind of decompression distillation device of the prior art is referring to accompanying drawing 1; Among the figure: evaporator 1, oil gas vent 6, exhaust of oil pipeline 10, vavuum pump 11, condenser 12, toxic emission pipeline 13, distillate 14, distillate collecting tank 15, used oil 18, evaporator support 19, radiator body 20.
Used oil 18 is annotated in evaporator 1 by material inlet valve and feeding line, and its injection rate accounts for about 1/2nd of evaporator 1 volume.Utilize heat carrier in radiator body 20 interior circulations, for the used oil 18 in the evaporator 1 carries out heat release, used oil 18 temperature after being heated constantly rise, when reaching the evaporating temperature of used oil 18 under its vacuum pressure, Evaporation Phenomenon begins to occur, in the used oil 18 at this moment, constantly having the high-temperature oil gas that is vaporized to break away from used oil 18 liquid levels constantly rises, the first half tank skin that part high-temperature oil gas is evaporated tank 1 makes its cooling liquid because of the temperature difference, again be back in the heated used oil 18 in bottom, the high-temperature oil gas that another part can not be cooled and liquefy enters in the exhaust of oil pipeline 10 via oil gas vent 6.
Enter the high-temperature oil gas in the exhaust of oil pipeline 10, passing through condenser 12 accepts to cool and enter in the distillate collecting tank 15, the distillate 14 that is liquefied through cooling is collected by distillate collecting tank 15, and the waste gas of the liquefaction that can not be cooled is discharged into the external world via toxic emission pipeline 13 and vavuum pump 11.
In the process of continual evaporation, in order to keep the optimal liquid level of evaporator 1 interior used oil 18, the used oil feed-line is communicated with the material inlet valve of evaporator 1, via the feeding line of evaporator 1, an amount of used oil 18 is supplemented to the inside of evaporator 1.
The defective that the distiller of this structure exists is: the first half tank skin that a part of high-temperature oil gas is evaporated tank 1 makes its cooling liquid because of the temperature difference, again be back in the heated used oil 18 in bottom, again be subjected to thermal evaporation, not only reduced thus the energy saving of device, also aggravate the degree of pyrolysis of distillation feed liquid, also reduced the working (machining) efficiency of device.
Disclosed another molecular still of Chinese patent, patent No. CN 101732881 A, its structure is that the acting part of distiller cylindrical shell is comprised of the vertical chuck of circle, it is radiator body that the heating agent conduction oil is arranged in chuck, in jacket cylinder, be provided with condenser, the jacket cylinder inwall to be provided with between the condenser by on lower flange, column and scrape the rotating cage device that lath forms, be provided with upper flange on jacket cylinder top, material inlet, the rotating shaft that is connected with the rotating cage device, reductor and motor, be respectively arranged with vacuum port in the jacket cylinder bottom, skewed slot, the heavy oil outlet, the light oil feeder, light oil outlets etc., the outside tube wall of this device condenser pipe and the radial distance between the cylinder inboard wall are set to 3.6cm～4.2cm.The internal diameter of cylindrical shell is arranged between 460mm～580mm, and working portion length is arranged between 1.3m～1.8m in the cylindrical shell.The shortcoming of this device is: because of the higher and miniaturization of its compact accuracy, be difficult to realize the cooked mode of long-time high production capacity, inadaptable processing higher boiling, thermal sensitivity is had relatively high expectations, include more impurity and the lower feed liquid of processing added value, otherwise: because outside tube wall and the radial distance setting between the cylinder inboard wall of condenser pipe only is 3.6cm～4.2cm, the jacket cylinder inwall to be provided with between the condenser by on lower flange, column and scrape the rotating cage device that lath forms, be very easy to make the feed liquid drop to be splashed on the outside tube wall of condenser pipe by cylinder inboard wall, form thus the short circuit evaporation; Carry out dirt and destroy because feed liquid includes compact precise space that solid formation that more Impurity Potential must produce will install within the short working time, device was entered in the time between overhauls(TBO) of growing within the working time of lacking.Because the miniaturization of device certainly will cause the working (machining) efficiency of device low.The apparatus structure more complicated causes the manufacturing cost of device and maintenance cost too high easily.
In sum: because the time between overhauls(TBO) of device is long, will shorten easily the production cycle of device, and add the factors such as working (machining) efficiency is low, and finally can cause the economic benefit of the too high and very difficult embodiment feed liquid processing of processing charges.
Description below will be quoted by the specification of this patent:
Feed liquid: refer to the material of purification to be distilled, both: the raw material of distillate product.
Distillate: feed liquid is separated the liquid phase fraction that obtains by cooling through the heating vaporization.
The flow process distance: in evaporation process, the feed liquid liquid level is apart from the height distance that can collect distillate.
