liquid liquid extracts the tower： |

The rotary table tower is equipped with
and circled round to mix the round extraction
equipment, by Reman development, the structure
was as Fig. 1 shows in 1951. Tower body
take the form of drum, his inboard wall
contain the regular ring, separate the tower
into a lot of light rooms, in the center
of the tower inserts from the top of the
tower in a pivot , the rotary table of worm
gear is mounted on it; The pivot is driven
by the motor of the top of the tower.
The top and bottom of the tower are the
clarifying area, the midsection of the tower
is for the extracting area. Two liquid that
contact each other, may the intermittence
accede to , is it accede to in succession
to add even, generally with the method of
joining in succession. When adopting and
flowing and operating, two kinds of liquid
are put from the top of the tower or the
tower bottom into the tower at the same
time , when adopting adverse current to
operate, no matter the interval feeds in
raw material or feeds in raw material in
succession , it is the heavy liquid that
is entered from the top of the tower, light
liquid enter by bottom from tower, at this
moment, light liquid and serious liquid
that kind can regard continuous phase as
。
一、Operation principle ：
After the electrical machinery is started
to change speeding, the disc is rotated
at a high speed, drive two phase to rotate
together, therefore produced shearing stress
in the liquid. Shearing stress is it produce
vortex in succession to make, in rapid state
of working up , make it break not to disperse,
form a lot of drops not of uniform size,
the coefficient that thus increased the
quality of spreading and contacting interfaces.
The existence of the regular ring , has
suppressed the axial to mix to a certain
extent, so the rotary table tower is extracted
with high efficiency 。
The high-efficient rotary table of Kuhni
extracts the tower, it increases the blade
of the worm gear on the rotary table , set
up a lot of vertical guards on the regular
ring on the basis of the thing that traditional
rotary table extracts the tower, will extract
and distinguish into a lot of mixing areas
and clarifying areas. Person who mix separate
stator a lot of light room , have rotary
table type of a device at the same pivot
mix the agitator in each small room. Made
up of a lot of small rooms too , separate
with the annular horizontal guard in the
clarifying area. It has traditional rotary
tables to extract the tower and disperse
function originally, there are clarification
areas separated at the same time, so can
condense more scattered repeatedly , for
reducing the mixing of axial, make theory
progression be up to 10 grades / rice. See
figures 。
二、Application ：
The rotary table tower is of simple structure,
maintain it conveniently. Because its operation
elasticity is large, the flux is large,
therefore in medicine , meticulous , petroleum
chemical industry, the rotary table tower
uses more extensive ：
1、 The liquid liquid is extracted: Own
interior acyl amine , furfural refined lubricating
oil, sulfur dioxide extract kerosene , propane
take off pitch , waste water take off the
phenol, refined , fermented liquid , sublimating
etc. fragrantly and bluly and plainly of
the edible oil ；
2、 Remove the micro- impurity ；
3、 Extraction with the response ；
