Description
Technical field
The invention belongs to technical field of alumina production, relates generally to a kind of configuration side of red- mud settlement and separation washing procedure
The technique that method, the separation of the Bayer process that is particularly suitable for use in alumina producer and washing use same size deep-cone settling groove.
Background technology
Red- mud settlement and separation washing procedure common equipment is deep-cone settling groove in Bayer process alumina producer production process, according to
The subsider of red mud amount and related experiment report selection appropriate size, because the device diameters are larger, red- mud settlement and separation washers
Sequence floor space is also larger.Separation at present and washing generally select same size subsider, if a separation and washing are common standby
Public standby subsider.The collocation method of such a technique generally use has following two：One kind configures for " banding ", i.e. institute
There is subsider central point to set point-blank, form a line, one pipe rack of unilateral setting is used in subsider charging aperture direction
In stringing, operation steel platform, platform edges are being set by subsider cell wall and pipe support pillar less than at about 1 meter of subsider charging aperture
Need to meet operating space away from cell body edge closest approach distance, usual 20 meters of subsiders of Ф about 8 meters of distance accordingly, the distance with
The increase of subsider diameter and increase.Cofferdam is set in red- mud settlement and separation washing zone surrounding, cofferdam inner region is not only thin but also long, no
Suitable for the alumina producer that the terrace discrepancy in elevation is larger；Another kind is configured for " eight pies ", i.e., all subsiders are matched somebody with somebody in two separate ranks and side by side
Put, set a pipe rack to be used for stringing among two row's subsiders, subsider charging aperture is arranged on pipe support direction, less than sedimentation
Set at about 1 meter of groove charging aperture by both sides subsider cell wall and intervalve post setting and operate steel platform, two row subsiders are nearest
Point distance need to meet operating space, and usual 20 meters of subsiders of Ф are accordingly apart from about 15 meters, and the distance is with subsider diameter
Increase and increase.Red- mud settlement and separation washing zone surrounding sets cofferdam, and cofferdam inner region is generally rectangular, because of two row subsiders simultaneously
Row configuration, two row subsider centre distances are larger, and red- mud settlement and separation washing zone floor space is also larger.
It is big floor space to be present in both the above collocation method, configures underaction, invests the problem of high.
The content of the invention
The present invention is exactly a kind of collocation method of red- mud settlement and separation washing procedure in order to solve the above problems and provide,
The purpose is to realize to reduce red- mud settlement and separation washing procedure floor space, reduce investment outlay.
For the above-mentioned purpose, the present invention is realized in：
A kind of collocation method of red- mud settlement and separation washing procedure, all subsiders in two separate ranks and are staggered；Two row are heavy
A pipe rack is set to be used for stringing among drop groove, pipe support lower channel is as red- mud settlement and separation washing zone access path；Low
Operation steel platform, red mud are set by both sides subsider cell wall and intervalve post setting at subsider charging aperture 0.8-1.2 rice
Sedimentation separation washing zone surrounding sets cofferdam.
Described subsider in two separate ranks and is staggered, and two row subsider central points is located in the flex point of " W ".
A pipe rack is set to be used for stringing among two described row subsiders, pipe support lower channel is washed as red- mud settlement and separation
Region access path is washed, pipe support bottom absolute altitude and pipe support width guarantee by middle-size and small-size tool car.
Described subsider charging aperture is arranged on pipe support direction.
Set and operate by both sides subsider cell wall and intervalve post setting at less than subsider charging aperture 0.8-1.2 rice
Steel platform, operation steel platform back gauge cell body edge closest approach distance need to meet operating space, and the distance is with subsider diameter
Increase and increase.
Described red- mud settlement and separation washing zone surrounding sets cofferdam, and cofferdam both ends set ramp, are easy to red- mud settlement and separation
Washing zone access path enters car.
Described cofferdam inner region is parallelogram.
Described cofferdam inner region is trapezoidal.
Operation steel is being set to put down by both sides subsider cell wall and intervalve post setting less than at about 1 meter of subsider charging aperture
Platform.
Advantages of the present invention and effect are：The technical program configuration is flexible, and floor space is small, reduces investment outlay.
