Description

A kind of combination type tenon structure glass reinforced plastic inner cylinder for coal-burning boiler chimney anticorrosion

Technical field

It is the present invention relates to a kind of technical field of fiber glass reinforced plastic chimney more particularly to a kind of for coal-burning boiler chimney anticorrosion Combination type tenon structure glass reinforced plastic inner cylinder.

Background technology

General flue gas is mordant to chimney, and the condition for producing corrosion is the presence that a. to be had corrosive medium;B. to With the presence of enough moisture;And c. will have certain ambient temperature.Above 2 points is to corrode the essential condition for occurring, and thirdly Determine the fast, slow of corrosion rate.According to other coal-burning power plants operation wet desulphurization device ruuning situation investigation, wet flue gas Moisture content in flue gas after desulfurization, can typically rise to 11%~13%, become saturated steam;Temperature drop is to 50 ± 5 DEG C. In the case, both possessed the temperature conditionss that condensation is produced, again with the presence of substantial amounts of moisture, while flue gas is become by negative pressure operation For operation under positive pressure, and flow velocity is reduced so that chimney internal condensation process is present in a large number, and inner wall of stack surface is condensed moisture film institute Cover, it is also possible to have substantial amounts of dew to form current on inner wall of stack surface, down trickle along inner wall of stack surface.According to certain money Material is introduced, and discharges flue gas Jing after wet desulphurization, without flue gas heat-exchange unit heat temperature raising, into chimney flue-gas temperature 50 ± 5 DEG C, inner wall of stack has serious condensation, the acid solution trickling having along barrel produced by condensation.The temperature of acid solution at 40 DEG C~80 DEG C, It is especially strong to the corrosivity of structural material.By taking steel as an example, etch ratio when 40 DEG C~80 DEG C is higher by other temperature About 3~8 times.

From the foregoing, before wet desulphurization, most altitude ranges of chimney are negative pressuren zone, are conducive to flue gas as early as possible Exclude, and after working as wet desulphurization device unlatching, in most altitude ranges of chimney, be changed into zone of positive pressure.And as occurred in chimney Malleation, then flue gas can pass through inner tube wall crack and technique preset slot, penetrate into armored concrete stack shell surface, causing corrosion Strengthen, the safe operation to chimney is unfavorable.It is for coal-burning power plant, general without GGH operating mode chimney input gas temperatures after desulfurization 50 DEG C or so are dropped to from 140 DEG C or so, causes smoke density to increase, reducing from suction capactity for chimney makes pressure point in chimney Cloth changes, and zone of positive pressure expands.

For most domestic power plant, after wet desulphurization, due to not installing GGH additional, flue-gas temperature only has 50 ± 5 DEG C or so, now the flue gas in whole altitude ranges of chimney will be changed into zone of positive pressure, except can cause severe corrosive flue gas and Its condensed fluid, the stronger lightweight acid-resisting concrete surface of water absorption is present in a large number on inner wall of stack body slit and all kinds of lacks Penetrate into outer caused by falling in gap, will also promote severe corrosive flue gas and condensed fluid, through the gap portion on brick lining surface Position, flow direction are not provided with the interior tube outer surface of anticorrosion sealing coat, support each Rotating fields platform surface of inner core, and its consequence will be pole For serious.

By certain power plant 2 × 125MW units, as a example by installing GGH, 180m chimney additional, after desulfurizer puts into operation, 30m height flue gases Temperature is 80 DEG C, now below chimney 60m parts, 5 DEG C lower than cigarette temperature or so of the surface temperature of inner wall of stack, with the increasing of height Plus, flue-gas temperature is gradually reduced, and the surface temperature of inner wall of stack gradually rises, more than 180m after, it is of substantially equal.That is, With this understanding, chimney lining material is constantly in the strong corrosive environments such as the moistening of wet flue gas dew, immersion.If now not Corresponding anticorrosive measure is taken, continues, by existing severe corrosive desulfurization fume, to reach outer through inner core under pressure Barrel inner surface condensation becomes severe corrosive dilute sulfuric acid liquid, no any Corrosion Protection, water absorption rate are very high common mixed Solidifying soil directly with this kind of strongly corrosion liquid Long Term Contact, its service life will be likely to shorter.

The SO of 1~50 μ L/L or so is there is in coal-fired plant flue gas3Steam, when flue-gas temperature is less than 200 DEG C, 99% SO above3Sulfuric acid vapor is generated with vapor.When flue-gas temperature is less than acid dew point, sulfuric acid vapor is condensed in chimney low temperature face Deposition generates acid solution, and corrosion is caused to chimney, affects the service life of chimney.The result of the test of the document shows, when simulation cigarette Gas bar part is:Sulfuric acid vapor content is 10 μ L/L or so, and 6% or so, flue gas after desulfurization temperature is 80 DEG C to water vapour content, cigarette Chimney wall surface temperature is 72 DEG C, and whole inner wall of stack face temperature change is less than 2 DEG C.When flue-gas temperature is 80 DEG C, as sulphuric acid steams The increase of vapour content, condensation of sulfuric acid deposition velocity are linearly increasing.When sulfuric acid vapor content is 40 μ L/L, deposition velocity reaches 0.139×10-6mol/m2.s, this is that at wall, sulfuric acid vapor concentration is constant due to condensing deposition velocity by Concentraton gradient control When, sulfureous in flue gas acid vapor concentration becomes governing factor, simultaneously because condensation acid strength keeps constant, water vapour condensation deposition Speed and sulfuric acid vapor condensation rate keep increasing in proportion.And there are some researches show, number of the flue-gas temperature less than dew point temperature Value is more, and condensation speed can tend to increase.

Can become apparent from from above-mentioned, after wet desulphurization, the corrosivity of wet flue gas are greatly enhanced, it is necessary to give foot Enough attention, otherwise, it will bring serious corrosion harmfulness.

In order to ensure safe operation of the desulfuration chimney after Anticorrosion Construction in the regular period, selected anticorrosive It must is fulfilled for following requirement:1), there must be enough resistances to elevated temperatures:Coal unit can be born in bypass smoke evacuation operating mode Under, thermal degradation of the high-temperature flue gas to anticorrosive;2), there must be enough decay resistances:Bituminous coal can be born Unit FGD normally runs, without under GGH operating modes, corrosion function of the desulfurization condensed fluid to anticorrosive, and having sufficiently high resistance to Corrosive nature retention rate;3), there must be sufficiently high adhesive strength with existing inner cylindrical surface:Guarantee in validity period, anticorrosion Material can be firmly adhered to inner cylindrical surface (for directly carrying out Anticorrosion Construction in inner lining surface);4), must with it is existing Inner core has the expansion match for meeting requirement:The linear expansion coefficient of anticorrosive, or consistent with existing inner core, or With sufficiently high elasticity, to adapt to during smoke temperature change, have between anticorrosive layer and inner core it is consistent expand with heat and contract with cold, It is unlikely to produce excessive uneven deformation and cause corrosion-resistant coating from inner core brick surface detackification;5), there must be suitable construction Environmental suitability:So as to being applied to, China is vast in territory, humiture change Present Natural Environment very greatly;6), must have There are dispensing, the simplification of construction:So as to the difficulty of the front technical training that reduces constructing, construction worker is allowed to grasp matching somebody with somebody for material as early as possible Material, Construction Points, adapt to the work high above the ground current conditions of chimney anticorrosion erosion construction;7), there must be rational cost performance, To guarantee that anticorrosion improvement expenses can be in the plan technological transformation cost range of power plant.
