Description
Technical field
The invention belongs to technical field of chemical, and in particular to a kind of rectifier unit.
Background technology
Rectifying is one of conventional operational means of chemical field, is generally realized using rectifying column.But essence conventional at present
Evaporate tower and there is following problem：
1st, it is easily caused catalyst inactivation in rectifying column containing impurity such as metal cations in raw material；
2nd, the filler in rectifying column is frangible, is easily pooled to rectifier bottoms and blocks the discharging opening of bottom of towe；
3rd, easily in housing bottom fouling after the material in reboiler is heated, reboiler heat transfer efficiency is caused to decline.
Above-mentioned the problem of, results in rectification efficiency reduction, and rectification effect is poor.
The content of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of rectifier unit, can effectively be carried using the present invention
High rectification efficiency, it is ensured that rectification effect.
The present invention uses following technical scheme：A kind of rectifier unit, including rectifying column, the device also include protection reactor
And reboiler；Protection reactor is connected by pipeline with the charging aperture I of rectifying column；Reboiler charging aperture passes through pipeline and rectifying column
Discharging opening I is connected, and reboiler discharging opening is connected with rectifying column charging aperture II；Reboiler includes being provided with heating tube in housing, housing,
The bottom of reboiler is provided with ultrasonic vibration device；Provided with going deep into the straight of bottom of towe and port closed at the discharging opening II of rectifying tower bottom
Aperture is provided with pipe, the side wall of straight tube.
Filter screen is provided with described reboiler charging aperture.
Described protection inside reactor is sequentially provided with support orifice plate, wire netting, quartz sand and catalyst layer from bottom to up.
During specific works, raw material removes the impurity such as metal cation therein, Ran Houjin first by protecting reactor
Enter rectifying column and carry out rectifying.Material in rectifying column can be heated by reboiler, and a part of steam enters again by rectifying column
Material mouth II enters in rectifying column, and light component rises, and heavy constituent falls on bottom of towe.The bottom of reboiler is provided with ultrasonic vibration device, makes
User can periodically open ultrasonic vibration device according to actual conditions, it is to avoid reboiler internal incrustation, after a period of time, then
Fouling in boiling device can be discharged by slag-drip opening.Filter screen is provided with reboiler charging aperture, can be avoided in advance in rectifying column
Slag charge enters reboiler, it is to avoid reboiler fouling is serious.
In summary, the present invention is simple in construction, can effectively improve rectification efficiency using the present invention, it is ensured that rectification effect.
