Abstract
The utility model relates to a distributor and a distillation apparatus comprising the same. The distributor is of a stainless steel pipe with one sealed end, and a plurality of discharge holes are uniformly distributed on the wall of one side of the stainless steel pipe axially; and when the distributor is arranged for distillation, the discharge holes are formed downwards, so that raw materials are sprayed downwards through the discharge holes, are contacted with light components in a stripping section, and then flow upwards to enter a rectifying section. The distributor enables the raw materials to be distributed uniformly, prevents channeling and enables fresh feed and light components vaporized in the stripping section to be contacted fully, thereby greatly improving the separation accuracy.
Description
Technical field
The distilling apparatus that the utility model relates to a kind of distributor for input of column and comprises this distributor, particularly relates to a kind of distilling apparatus that is applicable to the quick-detachable distributor of laboratory input of column and comprises this distributor.
Background technology
Distil process is one of technique important in petrochemical industry, mainly carries out separation of products.Principle is according to the boiling point difference of each component in raw material to be separated, is separated by distillating method.
Raw material enters destilling tower through being heated to predetermined temperature (200～300 DEG C, according to the weight situation adjustment of feedstock oil).Feedstock oil carries out air-distillation in destilling tower, and tower top is provided with backflow, establishes reboiler at the bottom of tower.Gas phase upwards flow, and reflux liquid light component on filler, carry out gas-liquid contact, carry out heat exchange and mass transfer.Heavy constituent in gas phase becomes liquid phase and flows downward, and light component in liquid phase becomes gas phase and upwards flows, and so realizes separating of heavy constituent and light component in gas phase.And liquid phase in charging enters stripping section together with the liquid phase of getting off from rectifying section, neutralize at stripping section that the gas phase of vaporizing contacts from reboiler, heat exchange and mass transfer, the light component in liquid phase enters gas phase, thereby ensures in liquid phase containing light component.So just complete the separation of weight component.
