Description
Technical field
The present invention relates to the chimney of coal-burning power plant, chemical industry, the application of environmental protection field, relate in particular to a kind of steam power station chimney that adopts the limestone-gypsum wet desulphurization and do not establish Smoke-heating device.
Background technology
Along with environmental requirement improves constantly, need install wet desulphurization device (FGD) when heat power plant boiler tail gas or industrial furnace exhaust emissions additional, absorb the objectionable impurities in the tail gas.Consider the cost problem, what use was more extensive and ripe at present is to adopt limestone-gypsum wet desulfurizing process (WFGD) and do not establish Smoke-heating device (GGH) after wet desulphurization, flue gas after desulfurization humidity increases, temperature reduces, flue gas the dewfall phenomenon occurs at the inwall of chimney, produce a large amount of condensate liquids, after the remaining dissolvings such as sulfur trioxide, form the very strong dilution heat of sulfuric acid of corrosivity in the flue gas.The corrosivity of flue gas is very big, begins both at home and abroad to select for use to have the strong glass fiber reinforced plastic chimney internal cylinder of decay resistance.The glass fiber reinforced plastic chimney have lightweight, high-strength, the rotproofness performance is good, the advantage that the regular maintenance cost is low obtains the approval in market, demand is constantly increasing.
Thermal power generation station-service glass fiber reinforced plastic chimney internal cylinder hangs or certainly stands in the support platform of steel concrete urceolus on by certain length segmentation the glass fiber reinforced plastic chimney internal cylinder according to chimney height at present, adopt the non-metal expansion joint of sealing to connect between the segmentation, the glass fiber reinforced plastic chimney internal cylinder divides intersegmental part that captation is set.The material of expansion joint is generally rubber, and aging easily under sour environment, application life is short, needs frequent replacing in design period in power plant, has a strong impact on the normal operation of Power Plant.In addition, the installation of expansion joint, maintenance and change relatively difficulty, it is purchased, the I﹠M expense is also than higher, and the captation in the segmentation of glass fiber reinforced plastic chimney internal cylinder is not good to subregion condensed water collecting effect, partial condensation liquid flows back to and flows in the flue, and flue is formed corrosion.
Summary of the invention
The object of the present invention is to provide a kind of chimney that adopts glass fiber reinforced plastic chimney internal cylinder discharging low temperature, high wet flue gas, wherein the glass fiber reinforced plastic chimney internal cylinder divides the intersegmental expansion joint connection that do not need to use.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of employing glass fiber reinforced plastic chimney internal cylinder discharging low temperature, the chimney of high wet flue gas, comprise the reinforced concrete chimney urceolus and have preseting length and the glass fiber reinforced plastic chimney internal cylinder segmentations that are connected by some, it is characterized in that: being connected in described glass fiber reinforced plastic chimney internal cylinder, to divide intersegmental end be the bell and spigot frame form, wherein, the top of bell and spigot frame form is plug, the bottom is slot, bracket of annular is set on the described glass fiber reinforced plastic chimney internal cylinder segmentation outer wall, and the segmentation of glass fiber reinforced plastic chimney internal cylinder is hung on the reinforced concrete chimney steel platform by described annular bracket.
Press such scheme, described plug from the bottom surface of slot and dual-side at intervals.
Press such scheme, described slot material is glass fiber reinforced plastic, and hand is stuck with paste the technology manufacturing.
Press such scheme, the cross section structure form of described slot is that dual-side has difference in height (highly unequal) rectangle and trapezium channel section form.
Press such scheme, the aspect ratio slot outer side edges height of described slot inner side edge hangs down certain distance.
Press such scheme, the perforate that it is 100mm～200mm that the outer side edges border of described slot is distributed with 1～2 diameter.
Press such scheme, the top of described perforate is under the inner side edge overhead height, and apart from slot bottom at intervals.
Press such scheme, plug should arrive the distance of the bottom of slot less than the bottom of perforate apart from the distance of slot bottom surface.
Press such scheme, described perforate is connected with discharging tube.
A kind of chimney that adopts glass fiber reinforced plastic chimney internal cylinder discharging low temperature, high wet flue gas provided by the present invention, compare with prior art and to have the following advantages: one, owing to do not adopt expansion joint between the segmentation of glass fiber reinforced plastic chimney, saved the purchasing of expansion joint, installed, maintenance and replacement cost; Its two, the chimney operation time produces a large amount of condensate liquids and flows into slot along glass fiber reinforced plastic chimney internal cylinder inwall, condensate liquid plays the fluid-tight effect, guarantees the airtight row of glass fiber reinforced plastic chimney in the running; Its three, slot can be used as captation and collects condensed water, need not to install captation in the segmentation of glass fiber reinforced plastic chimney internal cylinder again; Its four all be corrosion-resistant and ganoid glass fiber reinforced plastic formation owing to constitute the material of glass fiber reinforced plastic chimney internal cylinder, so this glass fiber reinforced plastic chimney long service life; Its five owing to be provided with the bell and spigot frame form between the segmentation of glass fiber reinforced plastic chimney, the design height of glass fiber reinforced plastic chimney can not be limited and be easy for installation.
