Specific embodiment
The structure in the present invention is further described with specific embodiment with reference to the accompanying drawing, but not as this
The restriction of invention.
The present invention is manually carried out by mechanical engagement, it is first determined gravitational precipitator toppling direction, according to field condition, in order to
Scraping collision blast-furnace body in toppling process is prevented, is first manually completely separated gravitational precipitator down-comer with blast-furnace body,
Then two concrete columns for toppling over side are all interrupted using extension arm crusher, topples over side and loses support gravitational precipitator
It is poured onto ground therewith, finally carries out furnace body using machinery and abolishes.It is specific as follows:
As shown in fig. 1~fig. 5, the embodiment of the invention discloses a kind of gravitational precipitator method for dismounting, comprising the following steps:
Step 1: construction personnel stands on deduster platform, and burning torch ties up spear and is cut into the pipeline connecting with extraneous pipe network
Fritter freely drops down on platform, and last thoroughly cutting is separated with the external world；
Step 1 is first first to separate gravitational precipitator with the component that periphery connects, and facilitates subsequent operation.
Step 2: one group of construction personnel is stood on deduster two down-comer junctions, by the horizontal cut-off part of down-comer
Reason, pipeline is since bottom support is also in stable state at this time；
Step 3: another group of construction personnel cuts down-comer piecemeal up to blast furnace platform, is located at 40.7 meters of platforms herein,
Down-comer piecemeal freely falling body is to ground, after all cuttings, since bottom is separated with deduster, and the part down-comer
By self gravitation effect, ground is dropped down onto, completes mask work；
By step 2 and step 3, gravitational precipitator and blast-furnace body are separated, it is not right when removing gravitational precipitator
Blast-furnace body has an impact.
Step 4: after all cutting process of two, top down-comer, construction personnel, will up to the platform of dust remover roof
Diameter is that the wire rope rope of 20mm is hung on the chimney above down-comer, and personnel withdraw to safe range；
Step 5: first abolishing No. 1 column using crusher, then abolishes No. 2 columns, and deduster bottom is equipped with 4 columns,
In No. 1 column and No. 2 columns be 2 adjacent columns；
The column of deduster as shown, be in sequence respectively No. 1 column, No. 2 columns, No. 4 columns and No. 3 columns,
Wherein No. 4 columns and No. 3 column reservations are not abolished.
Step 6: being the wirerope of extension using 460 type shear breaker distant range tractions in advance, realizes directional dismantling dedusting
Device is simultaneously poured onto ground.
Specifically, 460 type shear breaker positions are not less than 80m away from gravitational precipitator, 30 ° of the positive east by north of lead
Position, by Wire pulling.
In step 4, construction personnel is first beaten with hammer before the platform of dust remover roof confirms the complete of platform
Good property, if corrosion carries out further work after being seriously laid with steel springboard again.
In step 5, when abolishing No. 1 column, the position by No. 1 column apart from 3 meters of ground is thoroughly interrupted.
In step 5, when abolishing No. 2 columns, the line of No. 3 columns and No. 4 columns is located at the line of No. 1 column and No. 2 columns and breaks
Between broken machine.
Play the role of protecting crusher, prevents from toppling over because of toppling over towards crusher and staff direction for deduster.
Crusher selects extension arm crusher herein.
In step 5, when abolishing No. 2 columns, the position by No. 2 columns apart from 3 meters of ground is gradually removed, when No. 2 column distances
When diameter at the position of 3 meters of ground becomes one third to a quarter of original diameter, stop abolishing.
No. 2 column original dimensions are 700mm × 700mm, abolish and stop abolishing when rear diameter is 250mm.
If disposably having abolished No. 2 columns, deduster cannot be made to topple over according to predetermined direction, while toppling over excessive velocities,
It is not easy to control.When No. 2 columns are broken straight thinner, draw deduster deduster can be allowed to incline towards predetermined direction by wirerope
?.Securely and reliably.
The above deduster is the abbreviation of gravitational precipitator.
Presently preferred embodiments of the present invention is described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, devices and structures not described in detail herein should be understood as gives reality with the common mode in this field
It applies；Anyone skilled in the art, without departing from the scope of the technical proposal of the invention, all using the disclosure above
Methods and technical content many possible changes and modifications are made to technical solution of the present invention, or be revised as equivalent variations etc.
Embodiment is imitated, this is not affected the essence of the present invention.Therefore, anything that does not depart from the technical scheme of the invention, foundation
Technical spirit of the invention any simple modifications, equivalents, and modifications made to the above embodiment, still fall within the present invention
In the range of technical solution protection.
