Description
Technical field
The present invention relates to a kind of replacing options of large scale equipment, especially a kind of separation list of horizontal three-stage cyclone separator
First replacing options.
Background technique
Three-stage cyclone separator is the third level in petroleum refining industry in fluid catalytic cracking distillation system energy recycle device
Cyclone separator, effect is the catalyst that two stage cyclone separator preceding in regenerator is failed to separate from regenerated flue gas
Separation of particles comes out, and the high temperature and high pressure flue gas purified is provided for smoke gas turbine machine, so that it is guaranteed that turbine operates steadily in the long term.
So three-stage cyclone separator is the key equipment for determining fluid catalytic cracking distillation system energy recycle device service life.
Since treating capacity changes, efficiency decline, a variety of causes such as the internals such as single tube, partition and expansion joint damage are needed to three-level whirlwind
Separator device is transformed and replaces.For current horizontal three-stage cyclone separator, there is no effectively to inner part
From the method that unit is replaced, generally integral product can only be removed and be replaced, replace long in time limit, heavy workload, at
This is very high.
Summary of the invention
That technical problem to be solved by the invention is to provide a kind of replacement process is quick and convenient, construction cost is lower and installs
The separative unit replacing options of horizontal three-stage cyclone separator with high accuracy.
The technical scheme of the invention to solve the technical problem is: a kind of separation of horizontal three-stage cyclone separator
Unit replacement method, comprising the following steps:
(1) vertically oriented support frame is set in the bottom of the lower case of horizontal three-stage cyclone separator, by old separation
Unit supports fixation along the vertical direction；
(2) cutting of upper body and external pipe is separated, then by upper body respectively with lower case and old point
It is cut off from unit, then hung upper body with loop wheel machine；
(3) old separative unit is sling with loop wheel machine from vertically oriented support frame, and is hung out from the top of lower case,
New separative unit is hung in loop wheel machine from the top of lower case again, is then put into the bottom of new separative unit vertically perpendicular
On straight positioning supporting frame；
(4) upper body originally dismantled is hung to the top of lower case with loop wheel machine, by upper body and lower case
Centering welding, then new separative unit and upper body centering are welded；
(5) restore the connection of upper body and external pipe；
(6) vertically oriented support frame is removed, the replacement process to separative unit is completed.
The vertically oriented support frame includes more horizontal shores, bearing diagonal beam, column and reinforcing beam, the peace
Dress hole group the first mounting hole corresponding with the bearing diagonal beam that includes quantity and quantity corresponding with the column second are pacified
Hole is filled, first mounting hole is located at the top of second mounting hole, and the lower end of the bearing diagonal beam supports setting
In first mounting hole, the upper end apical grafting of the bearing diagonal beam is supported on the bottom conical surface of the separative unit
On, bearing diagonal beam described in more is uniformly distributed around the separative unit, and the horizontal shore is fixed at phase
Between bearing diagonal beam described in adjacent two, the bottom end of the column is arranged in second mounting hole, and described is vertical
The junction of the horizontal shore and the bearing diagonal beam, the reinforcing beam branch is arranged in the vertical apical grafting in the top of column
Support is arranged between the bearing diagonal beam and the column.Each supporting beam and column cooperate, and support strength is higher,
The upper end apical grafting of bearing diagonal beam is supported on the bottom conical surface of separative unit, is played the positioning action to separative unit, is improved
Position precision when separative unit centering welds, greatly reduces difficulty of construction.
Be provided between the bearing diagonal beam and the lower case the first arc installation backing plate, the column with
Be provided between the lower case the second arc installation backing plate, the top of the bearing diagonal beam be fixedly installed with it is described
Separative unit bottom cone match curved support backing plate.It is easy for installation, further enhance the positioning to separative unit
Effect.
The quantity of the bearing diagonal beam is the six roots of sensation.Support and locating effect are preferable and easy for installation.
When vertically oriented support frame is arranged, mounting hole group is first opened up on the lining of the bottom of lower case, is being installed
Vertically oriented support frame is set in the group of hole, old separative unit is supported into fixation along the vertical direction；Removing vertically oriented support
After frame, restore the lining being arranged in mounting hole group.
Before new separative unit and upper body centering welding, lifting lug and guide chain are first set in upper body, will be led
Chain is connect with the side of new separative unit, is arranged one for the same of centering in the center of the bottom of new separative unit
Heart degree measures line, and one piece of concentricity is arranged in the bottom of concentricity measurement line and measures plummet, when new separative unit and upper case
When body centering, judge whether the concentricity of new separative unit meets the requirements by the position of measurement concentricity measurement plummet,
The angle position of new separative unit is adjusted until concentricity meets the requirements by guide chain when undesirable.
Compared with the prior art, the advantages of the present invention are as follows elder generations in the bottom of the lower case of horizontal three-stage cyclone separator
Vertically oriented support frame is set, old separative unit is supported into fixation along the vertical direction, then upper body and external pipe are cut
Cut separation, then by upper body respectively and after lower case and the cutting of old separative unit, by crane by upper body with it is old
Separative unit successively hang out respectively, the individual weight of each section is relatively small, therefore requires the crane capacity of crane opposite
It is lower；It, will be original with loop wheel machine after the bottom of new separative unit is put into vertically oriented support frame inner support with crane fixing
The upper body of disassembly is hung to the top of lower case, and upper body and lower case centering are welded, then by new separation list
Member is welded with upper body centering, then restores the connection of upper body and external pipe, since new separative unit is vertical
Positioning supporting frame positioning, therefore difficulty of construction and the time of new separative unit centering welding are greatly reduced, it effectively increases
Installation accuracy shortens the whole duration, and entire replacement process is very quick and convenient, and construction cost is lower, saves material.
