Description
Technical field
This utility model relates to a kind of carbon five fractionating technology, a kind of solvent regeneration system.
Background technology
Carbon five is the resource of a kind of preciousness, can produce the chemical products of a series of high added values by it,
The exploitation of countries in the world common concern carbon five.
Carbon five has another name called lighter hydrocarbons, and China produces nearly ten million ton per year, but effectively utilizing of carbon five is always a difficulty
Topic.In carbon five fractional distillation process, containing the solvent of number of polymers, it is impossible to enter solvent refining tower and enter
Row separates.
Utility model content
For in carbon in prior art five fractional distillation process, containing the solvent of number of polymers, it is impossible to enter
Solvent refining tower carries out the deficiencies such as separation, and the technical problems to be solved in the utility model is to provide one can
By the solvent extraction containing polymer out, by the solvent regeneration system of polymer collection China and foreign countries row.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
This utility model one solvent regeneration system, including: solvent reclamation still, heat exchanger and solvent
Tank, wherein the material inlet of solvent reclamation still is connected to solvent intake pipeline, and the gas phase of solvent reclamation still goes out
Mouth is connected with heat exchanger, and the gaseous phase outlet of heat exchanger is connected with vacuum lines, and lower liquidus mouth is connected to molten
Agent tank；The bottom of solvent reclamation still is provided with coke discharging mouth.
Being provided with internal exchanger in solvent reclamation still, the heat exchange medium that internal exchanger is passed through is steam.
The heat exchange medium that heat exchanger is passed through is recirculated water, and temperature is not less than 26 DEG C.
This utility model has the advantages that and advantage:
1. this utility model evacuation solvent regeneration system, by suitable temperature and the adjustment of vacuum,
By the solvent extraction containing polymer out, by polymer collection China and foreign countries row.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein, 1 is solvent reclamation still, and 2 is heat exchanger, and 3 is solvent tank, and 4 is recirculated water return pipe
Line, 5 is recirculated water water-line, and 6 is vacuum lines, and 7 is internal exchanger, and 8 enter for steam
Mouthful, 9 is condensate outlet, and 10 is coke discharging mouth, and 11 is material inlet.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further elaborated.
As it is shown in figure 1, this utility model one solvent regeneration system, including: solvent reclamation still 1, change
Hot device 2 and solvent tank 3, wherein the material inlet 11 of solvent reclamation still 1 is connected to solvent intake pipeline
(solvent in this contains number of polymers), the gaseous phase outlet of solvent reclamation still 1 is connected with heat exchanger 2,
The gaseous phase outlet of heat exchanger 2 is connected with vacuum lines 6, and lower liquidus mouth is connected to solvent tank 3；Solvent is again
The bottom of raw still 1 is provided with coke discharging mouth 10, gets rid of due to the accumulation of equipment long-play for intermittence
Tar and polymer.
Being provided with internal exchanger 7 in solvent reclamation still 1, the heat exchange medium that internal exchanger 7 is passed through is
Steam.
The heat exchange medium that heat exchanger 2 is passed through is the recirculated water that temperature is not less than 26 DEG C.
There is polymer through the solvent of solvent reclamation still 1 of material inlet 11 input, and the boiling point of solvent is
More than 154 degree, heated by internal exchanger 7 in solvent reclamation still 1, add the effect of evacuation
The solvent held is steamed out, then after heat exchanger 2 cools down, polymer is fallen and collected in tank, collection China and foreign countries
Row.
This utility model is by suitable temperature and the adjustment of vacuum, from the solvent containing polymer
Extract the solvent recycling of purity more than 90%.
