Description
Technical field
The present invention relates to a kind of reinforced concrete chimney cylinder head and preparation method thereof, belong to aluminium industry reinforced concrete chimney
Cylinder head domain.
Background technology
With continuing to increase for national environmental protection policy dynamics is implemented in aluminium industry, each Chinalco increases flue gas desulfurization power
Degree, increase flue gas desulfurization device.Although after wet flue gas desulfurizer is installed additional, about 90%~95% SO in flue gas2Quilt
Removed from flue gas.But due to introducing substantial amounts of moisture in the flue gas after desulfurization and flue-gas temperature be down into 50 ± 5
DEG C or so, so that the flue gas after desulfurization is provided with very strong corrosivity.Chimney barrel head eminence smoke temperature change is very fast,
Easily condense, extent of corrosion is even more serious, so chimney barrel head is one of key position of chimney anticorrosion.In some standard drawings
Referral uses special steel as anticorrosion element, but not easy-maintaining in chimney top work high above the ground, and special material is not
Easy small purchases, how more preferably to ensure that cylinder head corrosion resistances and security are that designing institute focuses on one of focus.
The content of the invention
It is an object of the invention to provide a kind of reinforced concrete chimney cylinder head and preparation method thereof, solves in the prior art
The problems such as existing cylinder head corrosion resistances and security.
The technical scheme is that：
A kind of reinforced concrete chimney cylinder is first, is beared down on one by carbon block, acidproof asbestos cord, acid resistant adhesive mortar and pre-embedded bolt are formed,
Carbon block is set to bear down on one at the top of reinforced concrete chimney, carbon block is beared down on one as partitioned organization, by reinforced concrete chimney top perimeter
Decile is evenly arranged；Adjacent carbon block stays seam between bearing down on one, stitch in the filling of acidproof asbestos cord, and with acid resistant adhesive mortar jointing.
Described reinforced concrete chimney cylinder is first, and carbon block is beared down on one to be connected admittedly between reinforced concrete chimney with pre-embedded bolt
It is fixed.
Described reinforced concrete chimney cylinder is first, and carbon block is beared down on one boxes out according to the position correspondence of pre-embedded bolt.
Described reinforced concrete chimney cylinder is first, and pre-embedded bolt uses stainless steel material.
Described reinforced concrete chimney cylinder is first, and carbon block is beared down on one as the groove type knot with fastening at the top of reinforced concrete chimney
Structure.
The first preparation method of described reinforced concrete chimney cylinder, sets carbon block to bear down on one at the top of reinforced concrete chimney,
Carbon block bear down on one piecemeal making, be evenly arranged according to reinforced concrete chimney top perimeter decile；Carbon block stays seam between bearing down on one, in seam
Clogged using acidproof asbestos cord, and supported the use with acid resistant adhesive mortar jointing, acidproof asbestos cord and acid resistant adhesive mortar；By carbon block bear down on one with
It can be connected between reinforced concrete chimney with pre-embedded bolt, carbon block is beared down on one boxes out according to the position correspondence of pre-embedded bolt, protects
Card bolt can pass through.
Advantages of the present invention and beneficial effect are：
The present invention, as raw material, needs size modulus to be processed into special bear down on one using aluminum electrolyzing cell used carbon block by chimney.
Because carbon block has good thermal conductivity, chemical stability and volume stability, can be corroded with high temperature resistant, anti-fused salt, Ke Yi
Corresponding technological requirement processing and fabricating is pressed by supporting charcoal ink factory of aluminium manufacturer, gathers materials on the spot, low cost.Furthermore, it is possible to produce standby in batches
With or change, the chimney life-span is guaranteed.So as to reach saving steel, reduce the effect of cost.
Brief description of the drawings
Fig. 1 is the sectional view of the present invention.
Fig. 2 is the top view of the present invention.
The carbon block that Fig. 3 is the present invention is beared down on one shaft side figure.
In figure：1. carbon block is beared down on one；2. acidproof asbestos cord；3. acid resistant adhesive mortar；4. reinforced concrete chimney；5. pre-embedded bolt；
6. hole.
Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
As shown in Figure 1 to Figure 3, reinforced concrete chimney cylinder head of the present invention is beared down on one 1, acidproof asbestos cord 2, acidproof glue by carbon block
Mud 3 and pre-embedded bolt 5 are formed, and concrete structure and preparation method are as follows：
Carbon block is set to bear down on one 1 at the top of reinforced concrete chimney 4, carbon block, which is beared down on one, 1 is and the top of reinforced concrete chimney 4 is detained
The groove type structure of conjunction, can piecemeal make, be evenly arranged according to the top perimeter decile of reinforced concrete chimney 4.Carbon block bear down on one 1 it
Between should stay seam, stitch in is clogged using acidproof asbestos cord 2, it is and supporting with the jointing of acid resistant adhesive mortar 3, acidproof asbestos cord 2 and acid resistant adhesive mortar 3
Use.It can be reliably connected to ensure carbon block to bear down on one between 1 and reinforced concrete chimney 4, be connected and (schemed with pre-embedded bolt 5
1- Fig. 2).Carbon block is beared down on one and 1 should box out 6 according to the position correspondence of pre-embedded bolt 5, ensures that pre-embedded bolt 5 can pass through (Fig. 3).
In order to ensure service life, pre-embedded bolt 5 should use stainless steel material.
As a result show, the present invention makes reinforced concrete chimney cylinder head using aluminum electrolyzing cell used carbon block, is beared down on one using carbon block
To bear down on one instead of special steel, it can be gathered materials on the spot from supporting carbon element factory, so as to the effect for reaching saving steel, reducing cost.And
, can be preferably corrosion-resistant and carbon block has good thermal conductivity, chemical stability and volume stability, reach and extend chimney
The purpose in life-span.
