Description
Technical field
The utility model is related to chimney fields, are a kind of vinyl ester resin Anti-corrosive chimney in detail.
Background technology
It is well known that S02, NOx are to cause one of major pollutants of atmosphere pollution, China is discharged into the 80% of air every year
Above S02 derives from the direct burning of coal.Due to the toxic and harmful gas such as sulfur-bearing itself, nitrogen in fire coal, air is caused sternly
Heavily contaminated is the main reason of acid rain.The double alkali desulfurization (FGD) of wet method, ozone denitrating technique are that most of boiler is general using unit
All over the desulphurization and denitration technique used, main purpose is to meet national environmental protection regulation, while reduce engineering cost.Using the work
During skill, smoke moisture is big, and moisture condensation forms condensation acid solution easily in chimney, and corrosivity is very strong, is that faced in the technique important is asked
One of topic, although 95% S02 is eliminated in flue gas, the flue gas moisture content after desulfurization but rises to 13% or so, becomes full
And vapor, temperature also drops to 45 DEG C~60 DEG C, far below the adiabatic condensation temperature of vapor, thus can in flue, chimney table
Face forms apparent moisture condensation flow, and serious corrosion is generated to desulfurizing tower and attached flue, chimney etc..
Recently for over ten years, the desulphurization denitration chimney form of " armored concrete outer barrel+FRP inner cylinders ", it has also become world combustion
The primary structure form of coal burning boiler desulphurization denitration chimney.It being capable of self-supporting by the fiber glass reinforced plastic chimney that whole winding shaping process produces
Weight, has excellent acid-resistant anti-corrosion performance, can cancel insulating layer.But the application of fiber glass reinforced plastic chimney at present mainly face it is as follows
Railway Project never thoroughly solves：(1) selection and structural reliability problem；(2) resistance to mild fire safety problem；(3) aging is asked
Topic.
Invention content
For overcome the deficiencies in the prior art, the utility model provides a kind of vinyl ester resin Anti-corrosive chimney, has higher
Flex stiffiness and thermal expansion antitypy, chimney natural vibration can be resisted, it is not easy to come off, it is not easy to crack, improve cigarette
Chimney strong acid antiseptic property improves the service life of chimney.
Technical solution is used by the utility model solves its technical problem：A kind of vinyl ester resin Anti-corrosive chimney,
Equipped with chimney base material, which is characterized in that chimney base material inner wall is coated with the bottoming for including vinyl ester resin, mountain flour and curing agent
Layer, prime coat inner wall post six layers of medium-alkali glass fibre woven roving, the middle alkali glass of innermost layer successively through interlayer vinyl ester resin
Fiberglass surfacing mat is posted through interlayer vinyl ester resin on glass fiber woven roving, envelope is coated on fiberglass surfacing mat inner wall
Face clay, adjacent two layers alkali containing glass fibre woven roving and adjacent alkali containing glass fibre woven roving are staggered with fiberglass surfacing mat and take
Position is connect, not less than 50mm, alkali containing glass fibre woven roving and the fiberglass surfacing mat overlap joint of same layer are not less than 50mm.
The beneficial effects of the utility model are, simple in structure, the vinyl ester resin erosion resistant coating and matrix of chimney stack inner wall
Binding force is strong, has higher flex stiffiness and thermal expansion antitypy, can resist chimney natural vibration, it is not easy to come off, it is not easy to
It cracks, improves chimney strong acid antiseptic property, improve the service life of chimney.

Specific embodiment
In Fig. 1, Fig. 2, Fig. 3, the utility model is equipped with chimney base material 1, and 1 inner wall of chimney base material is coated with comprising vinyl esters
The prime coat 2 of resin, mountain flour and curing agent posts alkali glass in six layers on 2 inner wall of prime coat successively through interlayer vinyl ester resin 4
Glass fiber woven roving 3 posts fiberglass surfacing on the medium-alkali glass fibre woven roving 3 of innermost layer through interlayer vinyl ester resin
Felt 5 is coated with cover clay 6, adjacent two layers alkali containing glass fibre woven roving and adjacent alkali glass on 5 inner wall of fiberglass surfacing mat
Fiber woven roving and fiberglass surfacing mat 5 are staggered lap position, not less than 50mm, the alkali containing glass fibre woven roving and glass of same layer
Glass fiber surface felt overlap joint is not less than 50mm.
The construction technology of the utility model is：
（1）Chimney base material treatment：Chimney base material barrel surfaces externally and internally is cleared up using tools such as polishing machine, wire brush, scrapers,
Remove surface smut, corrosion patch, the visible base material true qualities in surface.
（2）Backing material simultaneously repairs uneven surface, weighs quantitative MFE-2 vinyl ester resins, is added in by regulation proportioning
Curing agent stirs evenly, and adds the quantitative accelerating agent of proportioning and continues to stir evenly, obtains bottom material, according to adding mountain flour by norm i.e.
Obtain coating.It will first be smeared at chimney turning, bend, reducing, three-way interface into seamlessly transitting using coating.
（3）Chimney wall inner surface is divided into several pieces of construction surfaces, checks every piece of base material construction surface, it is qualified after first brush bottom material
1, dry tack free, begins to use coating to repair depressed area after twenty minutes, and brush the 2nd is beaten after being smoothed out using plasterer's trowel, scraper
Bottom material, natural curing 30 minutes, so as to form prime coat.
（4）After 30 minutes, the 1 MFE-2 vinyl ester resins being configured uniformly are brushed on prime coat, alkali in pasting immediately
1 layer of glass fibre woven roving, medium-alkali glass fibre woven roving is infiltrated, and is excluded using bubble rotary broom is caught up with to roll bubble, 20 points
Zhong Hou, then 1 MFE-2 vinyl ester resins are brushed, then paste 1 layer of medium-alkali glass fibre woven roving, so repeatedly, 6 layers are pasted altogether
Medium-alkali glass fibre woven roving.Pay attention to often pasting 1 layer, it is necessary to roll bubble and exclude, there is not allowed that gauffer, same layer cloth overlaps not
Less than 50mm（See Fig. 3）, upper and lower two layers of cloth is staggered lap position, not less than 50mm（See Fig. 2）.
（5）Medium-alkali glass fibre woven roving, which pastes, to be finished, and is further examined, and finds phenomena such as bubble, impurity wrap,
Processing is chiseled in part, is tamped using coating.
（6）1 layer of fiberglass surfacing mat is finally pasted, also requires that lap-joint is not less than 50mm（See Fig. 2）, finally again
Even brushing cover clay, natural curing is for 24 hours.
（7）In entire work progress, the time slot for needing to wait in processing procedure is pasted, another piece can be taken into account simultaneously
Construction surface related work, to improve working efficiency.It is so alternately reciprocal, until the construction of chimney inner surface erosion resistant coating is completed.
（8）The construction natural curing period is completed in inner surface, according to related request, to the cleaning of chimney outer surface, mopping.
（9）Site clearing, handles waste, and construction is completed.
