Feed liquid 3 is any one organic matter slurries that need distilation to separate.
Thermoregulator 7 is the parts that can carry out heat release to feed liquid 3, and in concrete enforcement, it can be a tube furnace or heat exchanger.
After being heated within the lower evaporimeter tank body 1 of decompression, feed liquid 3 liquid layers are thicker, and heating degree is higher, strong boil-over phenomenon more easily occurs and the degree of purity of cut is declined, and therefore should appropriateness grasp the work condition environment of feed liquid 3 liquid layer thickness and heating degree after being heated; After being heated within the lower evaporimeter tank body 1 of decompression, the boiling range distance of feed liquid 3 and the first flow diverter import 13 is shorter, its evaporation efficiency is higher, but more easily there is entrainment and cause short circuit evaporation, and the degree of purity of cut is declined, therefore should shorten the boiling range distance of feed liquid 3 and the first flow diverter import 13 after being heated as far as possible, but should avoid above-mentioned drawback, regulating thus definite boiling range distance is suitable boiling range distance; Originally stating under mechanism, after being heated, feed liquid 3 liquid layers are thinner, heating degree is lower, more be conducive to efficiently purify for organic matter feed liquid 3 under shorter boiling range distance, therefore should be according to factors such as 3 liquid layer thickness of feed liquid after being heated and heating degrees, regulate and determine its suitable boiling range distance.
The operation principle of device:
Feed liquid 3 is by the upper end of threeway pipeline 6, passes through within from outside valve 9, interior road valve 8 enter evaporimeter tank body 1 via feed pipe 10, and its shot accounts for 1/2nd left and right of evaporimeter tank body 1 volume.
Open vavuum pump 21, make the air pressure within evaporimeter tank body 1 enter vacuum decompression state.
Road valve 8 in opening, close from outside valve 9, the pump 5 that turns on the power, makes postpone drainage conduit 4, kinetic pump 5, threeway pipeline 6, thermoregulator 7, interior road valve 8, feed pipe 10 of feed liquid 3 within evaporimeter tank body 1 again enter within evaporimeter tank body 1 and circulate.
Open temp adjuster 7, make it carry out heat release to feed liquid 3, in the time that the feed liquid 3 circulating obtains the evaporating temperature under its vacuum pressure, vaporization phase transformation starts to occur, now after being heated in evaporimeter tank body 1 in feed liquid 3, constantly there is the high temperature gas phase fraction being vaporized to change with the states of matter of expansion several times volume, depart from feed liquid 3 and accept the cooling of the first flow diverter import 13 top gas-phase space inner condensers via gas phase channel; There is liquefaction phase transformation again to shrink within the states of matter of several times volume changes liquefy and fall into the first flow diverter import 13 in the cut that can be liquefied after cooling, falls into liquid fraction within the first flow diverter import 13 collected by the first distillate drum 27 via the first drainage pipeline 23; The cut that can not be liquefied after cooling is discharged into the external world via tank body upper port 15, top layer decompression exhaust mouth 17, decompression exhaust pipeline 18, check valve 20 by vavuum pump 21 with the form of gas phase states of matter.
Above-mentioned condenser is any one or two or more combination in spiral condenser 14, plate-type condenser 12, shell and tube condenser 16; In concrete enforcement, can be according to technique and operating mode needs, select one, two or three wherein to carry out Joint Implementation.
Under the parsing of above-mentioned operation principle, by decompression operating mode under built-in the first flow diverter 24 evaporimeter tank body 1 and be arranged at the condenser on the first flow diverter import 13, make to be subject to occur in thermal evaporation process the cut of vaporization phase transformation, under the effect of condenser, again there is liquefaction phase transformation and become liquid fraction, make thus to keep certain vacuum within evaporimeter tank body 1, for feed liquid 3 evaporation at a lower temperature provides condition; The advantages such as that this device also possesses is simple in structure, low cost of manufacture, maintenance cost is low, operation easier is little; Feed liquid 3 liquid levels by after being heated are apart from the vertical suitable boiling range distance of the first flow diverter imports 13, can efficiently suppress the cut generation entrainment in evaporation and cause short circuit to be evaporated; By the Joint Implementation of multiple condenser, can significantly improve the cooling effect of gas phase fraction.
If by shell and tube condenser 16 and spiral condenser 14 Joint Implementation of connecting, coolant media, successively for the cooling heat transferring of shell and tube condenser 16 and spiral condenser 14, can significantly be improved to the heat exchange efficiency of coolant media so.
If by spiral condenser 14 refrigerant import and refrigerant exit communicate with the coolant media that heat energy can recycle, the refrigerant import of shell and tube condenser 16 and refrigerant exit are communicated with other coolant media, can significantly improve so the utilization ratio that heats the energy that can and freeze; Originally the coolant media that the heat energy of stating can recycle is for the feed liquid 3 before above-mentioned distillation.
Plate-type condenser 12 is heat exchangers that deliberately carry out exchange heat acting by metallic plate, if use the air of nature circulation as coolant media, this condenser does not need other energy resource consumption at work so.
The cooling effect of gas phase fraction is better, and the vacuum keeping within evaporimeter tank body 1 is higher.
Feed liquid 3 liquid levels after being heated refer to and absorb feed liquid 3 liquid levels in carburation by evaporation state after thermoregulator 7 heats.
Feed liquid 3 liquid levels in carburation by evaporation state are the boiling range distances under objective operating mode apart from the distance of the first flow diverter import 13.
In order to make the first flow diverter import 13 collect more the cut that liquefaction phase transformation occurs, to the gas-phase space between condenser, be provided with suitable for reading large lower young cast the first drainage plate 11 being connected with evaporimeter tank body 1 inwall in described the first flow diverter import 13.
For the feed liquid 3 after making to be heated obtains more vaporization time and vaporization area and improves its vaporization efficency compared with short boiling range distance, avoids that liquid layer because of feed liquid after being heated 3 is blocked up strong boil-over phenomenon occurs to be caused within entrainment causes that feed liquid 3 is excessive and enter cut, to the gas-phase space between feed liquid liquid level 26, be provided with the spiral vaporization tank 25 that upper end is communicated with the outlet of feed pipe 10, lower end is the outlet of dustpan shape, entirety is stacking spiral in described the first flow diverter import 13.
In order to suppress the first flow diverter 24 lower ends because cause gas phase fraction to liquefy because of loss of heat compared with low temperature, within being again back to feed liquid 3; Avoid acting on the inside and outside pressure reduction of the first flow diverter 24 double Shells and damage to the first flow diverter 24 double Shells suppress liquid fraction and flow in the space that double Shell forms, described the first flow diverter 24 is double-layer shell structure, in the space forming, is provided with heat-barrier material at double Shell; At the described double Shell constant voltage mouth 22 communicating with its inside that is provided with on the outer casing of the first flow diverter 24, constant voltage pipeline 19 one end are communicated with double Shell constant voltage mouth 22, and other end rotation is communicated with the vacuum decompression space communicating with the interior gas-phase space of evaporimeter tank body 1 downwards.
