Description
Technical field
The present invention relates to a kind of whole self-supporting glass reinforced plastic inner cylinder supporting arrangements, are set to floss hole region, belong to chimney
Technique of design and construction field.
Background technology
Wet Flue Gas Desulfurization Technique implements more than ten year in China, performs deeds of valour in battle for the defended war of China blue sky.Wet method
The flue gas of desulfurization discharge is " wet flue gas ", and the chimney of discharge " wet flue gas " is " Wet chimney ", and " wet flue gas " causes " Wet chimney "
Serious corrosiveness.By chimney anticorrosion erosion practice and summary of experience for many years, thought both at home and abroad using " in fiberglass
Cylinder " is " Wet chimney " corrosion-resistant ideal scheme.The implementation of the program be exactly will common single-cylinder type reinforced concrete chimney originally, change
To make as outer barrel be armored concrete barrel, the telescopic reinforced concrete chimney that inner cylinder is fiberglass form.
It is that newly-built sleeve chimney generally uses scheme using " suspension type " glass reinforced plastic inner cylinder.But existing chimney anticorrosion is changed
It makes, using " suspension type " glass reinforced plastic inner cylinder, there are many technology barriers.It is mainly reflected in：Existing chimney design standard is unsatisfactory for
The requirement of " suspension type " internal cylinder chimney；Bearing capacity or design construction are unsatisfactory for requiring；Existing chimney top corrosion and damage, it is unfavorable
In the implementation of suspension solutions；The transport that the dimension of opening of chimney bottom floss hole or chimney manhole is unsatisfactory for glass reinforced plastic inner cylinder is wanted
It asks.For these reasons, if using " whole self-supporting " glass reinforced plastic inner cylinder, and connect in chimney top lifting and chimney top opening
It connects, above-mentioned difficulties will be overcome completely.
However, in floss hole region since glass reinforced plastic inner cylinder bore size is big, inner cylinder bearing capacity is significantly weakened, is made
Cannot achieve " whole support oneself " truly at glass reinforced plastic inner cylinder, it usually needs the inner cylinder (or flue) in floss hole region with
Upper inner cylinder is connected by expansion joint, i.e.,：Floss hole region inner cylinder (or flue) self-supporting, floss hole upper inner cylinder self-supporting,
Between by telescopic joint connect.This embodiment disadvantage mainly has：Inner cylinder vertically needs expansion joint, increase follow-up maintenance at
This；Top glass steel inner cylinder needs a set of independent weight bearing supporting system, increases project cost and duration；Flue region inner cylinder
(or flue) often uses hand to paste fiberglass, and quality is unreliable etc..
Invention content
The technical problem to be solved by the present invention is to：It how solves so that using " whole self-supporting " glass reinforced plastic inner cylinder in cigarette
Crossing area meets bearing capacity requirement.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is to provide a kind of whole self-supporting glass reinforced plastic inner cylinders
Supporting arrangement, which is characterized in that include successively from outside to inside the steel construction outer barrel for load-bearing, composite material and be used for corrosion-resistant
Inner cylinder, the top of steel construction outer barrel are equipped with the steel perimeter beam of the separate glass steel inner cylinder for supporting top, under steel construction outer barrel
On the basis of portion is supported on.
Preferably, the steel construction outer barrel is connect with external steel plate, and inner cylinder is connect with inner wall, and the outside of inner wall is equipped with method
It is blue；Flange is directly connected to inner flue or is connect with inner flue by expansion joint.
Preferably, the outside of the steel construction outer barrel is equipped with the steel frame being made of steel column and horizontal girder steel, steel frame
On be supported with the steel perimeter beam on floss hole top, on the basis of steel frame is set to.
Preferably, the inner cylinder is glass reinforced plastic inner cylinder, and inner wall is fiberglass inner wall, and composite material is multiple for polymer foaming
Condensation material.
Preferably, the material used in the inner cylinder and inner wall is borosilicate glass brick, and composite material is binder.
Preferably, the material used in the inner cylinder and inner wall is titanium-based or nickel-base material.
Preferably, the basis is chimney dust stratification platform.
The present invention is suitable for selection self-supporting glass reinforced plastic inner cylinder chimney anticorrosion scheme or Steel Inner Core of Chimney anti-corrosion improvement project.
Change especially suitable for the anticorrosion improvement project of existing monotubular reinforced concrete chimney and the floss hole region of Steel Inner Core of Chimney
It makes.Device through the invention, it may not be necessary to existing chimney dust stratification platform is removed, a large amount of engineering consumption are saved, it can be directly sharp
The basis that supporting arrangement is made of dust stratification platform, reduces investment outlay and the construction period, is conducive to existing chimney anticorrosion and is transformed.
The invention enables floss hole region glass reinforced plastic inner cylinder and floss hole upper inner cylinders to be connected, vertical load-carrying members it
Between be not provided with expansion joint, connected using spigot-and-socket expansion joint only in the glass reinforced plastic inner cylinder of non-bearing, entire inner cylinder meets carrying
Ability and anti-corrosion function requirement.
