Description
Technical field
A kind of tar decompression distillation system of the utility model, belongs to chemical equipment technical field.
Background technique
In tar atmospheric and vacuum distillation technique, the anhydrous tar and fraction tower bottom carbon black oil extracted out from dehydration tower bottom are recycled
Heat exchange causes the fluctuation of fraction column bottom temperature larger, and the vapo(u)rizing temperature distribution temperature difference is smaller in tower, and carbon black oil compositional purity is inadequate, matter
Amount fluctuation is larger；The yield and quality of each product are relatively unstable, the temperature drift of carbon black oil, and coal gas consumption is relatively large.
Utility model content
To solve the shortcomings of the prior art, the utility model discloses a kind of tar decompression distillation system, the systems
Carbon black oil quality can be stablized, mixed triolein yield is promoted, reduce carbon black oil temperature, achieved the purpose that energy-saving.
The utility model is achieved through the following technical solutions:
A kind of tar decompression distillation system, including dehydrating tower and fraction tower, the dehydration tower bottom anhydrous tar outlet
Road connects maltha cooler, and the maltha cooler thermal tar outlet conduit connects the fraction tower feed inlet, described to evaporate
Tower bottom maltha outlet conduit is divided to connect the maltha cooler, the cold asphalt outlet pipeline of the maltha cooler connects
Connect carbon black production device.
The feed inlet is located in the middle part of the fraction tower.
The fraction tower is normal pressure or vacuum distillation tower.
The dehydration tower bottom anhydrous tar outlet is provided with anhydrous tar drawing pump.
The fraction tower bottom maltha outlet is provided with maltha extraction pump.
The utility model has the advantages that compared with prior art
The maltha extraction heat exchange of the anhydrous tar that the utility model is extracted out from dehydration tower bottom and fraction tower bottom is laggard
Enter in the middle part of fraction tower, present 185 DEG C reduced into the temperature of fraction tower from original 210 DEG C make the temperature of fraction tower bottom
Degree is widened with middle portion temperature amplitude.Heavy component in tar will not rise to fraction tower top, the lighter component in tar will not under
The bottom of fraction tower is dropped to, lighter component in carbon black oil is reduced, the quality of carbon black oil is more stable；Improve the yield of mixed triolein.
After carbon black oil extraction heat exchange by the anhydrous tar and fraction tower bottom of dehydration tower bottom extraction, carbon black oil temperature
130 DEG C till now are reduced from original 140 DEG C hereinafter, making carbon black oil more safety and environmental protection during storage.
It will be dehydrated the process of the anhydrous tar and fraction tower bottom carbon black oil cycle heat exchange of tower bottom extraction compared with conventional,
The utility model enters after being exchanged heat from the carbon black oil that the anhydrous tar that dehydration tower bottom is extracted out is produced with fraction tower bottom to be evaporated
Part tower, reduces the thermal losses of carbon black oil circulation, reduces the consumption of coal gas.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.
FIG. 1 is a schematic structural view of the utility model.
In figure, 1 it is dehydrating tower, 2 is fraction tower, 3 is anhydrous tar outlet, 4 is maltha cooler, 5 is that thermal tar goes out
Mouthful, 6 be feed inlet, 7 be maltha outlet, 8 be cold asphalt outlet, 9 be anhydrous tar drawing pump, 10 be maltha extraction pump,
11 it is thermometer, 12 is cooler.
Specific embodiment
The utility model is described in further detail combined with specific embodiments below, but the protection of the utility model
Range is not limited to these examples, it is all be included in without departing substantially from the change of the utility model design or equivalent substitute it is practical
Within novel protection scope.
As shown in Figure 1.
Embodiment
