Description
Technical field
The present invention relates to one kind can fundamentally solve coal-fired chimney lining because vibrating, rocking, the factor such as stress concentration
The technical barriers such as the chimney lining crack, delamination, seepage, the corrosion that cause, make coal-fired chimney anticorrosion security performance thoroughly be changed
Coal fired power plant flue gas desulfurization Anti-corrosive chimney and system kind and that can greatly extend coal-fired chimney service life and reduction manufacturing cost
Make method, category coal-burning power plant's chimney manufacture field.
Background technology
Chimney is the important component part of thermal power generation system, carries and the flue gas of boiler combustion is discharged in atmosphere
Important task.In the non-desulfurization epoch, flue gas is in line to atmosphere from boiler Jing chimneys.The interior anti-corrosion of this period chimney is mainly resistance to height
The etch-proof brick inner liner technology of temperature, belongs to dry flue system, and smoke discharging temperature is about：125-180 DEG C, do not produce substantially
Corrosion；And the arrival in desulfurization epoch at present, then the working environment of chimney is greatly changed, dry flue originally becomes wet cigarette
Road, boiler flue corrosion environment severe exacerbation.Show：A. corrosive medium：SO2、SO3；B. temperature<Acid dew point, acid solution is along walling of flue
Trickling downwards, period evaporates repeatedly, trickles, and be chronically at acid invades blister state, causes corrosion；C. flue internal pressure ﹤ external pressure, there is negative
Pressure；D. the usual state of etch ratio is fast 3～8 times.So working environment brings safely great wind to the operation of chimney
Danger, corrosion leakage happens occasionally, and the service life for causing chimney is greatly shortened, and directly affects the normal power generation of power plant.Around this
One theme, extensive research and commercial Application discussion is expanded to chimney anticorrosion, and conclude has following two big types at present：
One is brick inside lining anti-corrosive sealant, such as interior to build various acidproof bricks, plate, is traditional anti-corrosion means, and its weak point is overall
Property is poor, is also easy to produce crack, causes seepage anti-corrosion；Two is the various anticorrosive paints of coating, such as corrosion-resistant glass-flake coating and lining patch
Applied corrosion resistant lining, such as titanium composite panel, but this class aseptic technic shows versatility because of the difference of material and technique.Such as：
A. the high performance corrosion resistant metal titanium plate of liner.But cost is high, solder technology has high demands, and weld seam is also easy to produce corrosion.B. spray resistance to
Etching glass squama resin resistant coating.Advantage is acidproof, high temperature resistant, impervious, but easily peeling or is come off.
The content of the invention
Purpose of design：The weak point in background technology, design one kind is avoided fundamentally to solve coal-fired chimney lining
In because vibrating, rocking, the technical barrier such as the factor such as stress concentration the chimney lining crack, delamination, seepage, the corrosion that cause, make combustion
Coal chimney anticorrosion security performance is thoroughly improved and can greatly be extended coal-fired chimney service life and reduced manufacturing cost
Coal fired power plant flue gas desulfurization Anti-corrosive chimney and preparation method.
Design：Can have no to discuss different drawing from background technology：Coal-fired chimney anticorrosion is caused to damage most direct factor
It is technological factor, rather than main material is caused intolerant to chemical preservation.Such as：Brick liner produce crack, the delamination of glass flake coatings,
Crack, weld corrosion of titanium composite panel etc. because chimney shape is tall and big, is easily vibrated, are rocked, and cause stress concentration and line of material swollen
Coefficient is uncoordinated etc., causes chimney anticorrosion slabbing seam and delamination to damage, thus exploitation is a kind of anti-shake dynamic, can dispersive stress concentrate,
And the aseptic technic of tunable difference linear expansion coefficient is the key of the technology of chimney anticorrosion.In order to realize this purpose.The present invention
1) from elastomeric material as chimney corrosion-proof lining layer, rather than the inner liner of other materials.2) select and have and rubber liner
The adhesive of layer and steel plate excellent bonds is used as rubber and the adhesive of inner wall of stack bonding.3) from rubber lined room temperature sulphur
Chemical industry skill, makes rubber have good shockproof, anticracking, antiseepage, protection against the tide, waterproof, resistance to ozone, weather-resistant, acid-proof alkaline.
Technical scheme 1：A kind of coal fired power plant flue gas desulfurization Anti-corrosive chimney, including chimney, the inner wall of stack scribbles one layer
Primer, scribbles an aspect glue on primer face, face glue is bonding with rubber lining.
Technical scheme 2：A kind of preparation method of coal fired power plant flue gas desulfurization Anti-corrosive chimney, chimney steel inner bag is manufactured and adopts
During dress method technique, anti-corrosion rubber lined construction line with rubber by first segment steel drum on ground is saved to most end one, then to chimney bottom lining
Glue, i.e.,：（1）Gluing sheet is served as a contrast on ground in the face of first segment chimney steel drum.Film length equivalent steel drum length deducts the reserved 300mm in two ends
×2=600mm.When starting patch, in inner wall of stack brush ground floor primer, after brush the second aspect glue of the rubber back side, it is attached in chimney
On wall.By that analogy, lining has pasted all of steel drum.The turned-out parcel of a part of sheet rubber of top end face of first segment chimney steel drum
Firmly chimney top end face and outside, in case corrosive medium pours in down a chimney seepage corrosion.（2）First segment steel drum holds up rear and second section steel drum
Be welded, to reserve two end 300mm × 2=600mm drum surface according to line with rubber PROCESS FOR TREATMENT, in inner wall of stack brush first
Layer primer, after brush the second aspect glue of the rubber back side, sheet rubber is vertically attached to the reserved two end 300mm × 2=600mm of chimney
Cylinder inboard wall on, film length should be the crimping of 600mm+60mm (each 30mm overlap edges up and down), the upper and lower sheet rubber mutual fissure of displacement.
（3）By that analogy, lining has pasted the cylinder of the reserved two end 300mm × 2=600mm of all steel drums.Finally, remove scaffold etc. to apply
Work facility, lining patch chimney bottom.The sheet rubber of bottom lining patch should turn over 30mm on bucket wall, and pressure viscosity is firm.
Compared with background technology, one is that, because rubber-type glue is flexible, the application adopts rubber-type glue energy to the present invention
Enough adapt to chimney deformation in use；Two is to become one after the bonding between rubber and rubber is bonded using rubber cement
Body, does not require construction temperature, it is not required that accelerates bonding by the temperature of flue gas in flue, and solves background technology
The vibration of presence, rock, the technical barrier such as crack, delamination, seepage, the corrosion that the factor such as stress concentration is caused；Three is due to cigarette
The anti-corrosion security performance of chimney has obtained thorough improvement, and the life-span of its chimney was up to more than 30 years, and construction technology simplifies, manufactures
Cost is decreased obviously；Four is the technological gap for having filled up chimney rubber anti-corrosive lining, changes the traditional structure and work of chimney anticorrosion
Skill.
