Description
Technical field
The present invention relates to a kind of smoke removal facility being combined by different materials, more particularly to a kind of steel-glass reinforced plastic
(Steel-FRP Chimney) compound smoke removal facility.
Background technology
Energy-conserving and environment-protective are a national important Sustainable development policies.At present, China's air discharges pollutants mainly to come
From the fume emission of thermal power generation, chemical industry, nonferrous smelting and the industry such as metallurgy sintered.Major pollutants are SO2, nitrogen oxygen in flue gas
Compound etc., content highest are SO2.Smoke-gas wet desulfurization (flue-gas desulphurization) is that China's application is most
Sulfur removal technology.Wet flue gas after wet desulphurization is in mainly following characteristics：
1) flue-gas temperature is low, about 50 DEG C or so；
2) smoke moisture is big, is saturation state；
3) SO2 removal efficiencies are big, and SO3 removal efficiencies are relatively low.
Although SO3 is less, under said temperature and humidity environment, dilute sulfuric acid is formd, it is very strong to cause flue gas
Corrosivity, very strong destruction is produced to chimney, destroyed for deep-etching grade.
Since two thousand four, China starts large area FGD desulfurization, and damage in various degree occurs in substantial amounts of chimney, directly and
Indirect loss is very huge.Up to this point, still without a set of economical and effective anti-corrosion solution.Current self-supporting
Steel stack is obvious because damping small Across-wind Resonance of Tall phenomenon.
The content of the invention
The technical problem to be solved in the present invention is：Providing one kind has self heat insulation function, meets structural strength needs
With anticorrosion requirement, the compound smoke removal facility of steel-glass reinforced plastic of construction costs is saved, is solved due to large area FGD desulfurization, largely
Chimney occur in various degree damage the problem of.
In order to solve the above-mentioned technical problem, set the technical scheme is that providing a kind of compound smoke evacuation of steel-glass reinforced plastic
Apply, it is characterised in that including two diameters different steel outer barrel and glass reinforced plastic inner cylinder, glass reinforced plastic inner cylinder is arranged at matched steel
In outer barrel, steel outer barrel is provided with support ring, and the bottom of glass reinforced plastic inner cylinder is in support ring, between steel outer barrel and glass reinforced plastic inner cylinder
Pass through polymeric foamable material composite joint.
Preferably, described glass reinforced plastic inner cylinder is linked together by bell and spigot frame or flange by segmentation inner cylinder and formed.
Preferably, described glass reinforced plastic inner cylinder is connected by segmentation inner cylinder by " L " shape bell and spigot frame or " u "-shaped bell and spigot frame
Be connected together composition；" L " shape bell and spigot frame includes the segmentation inner cylinder that one end is " L " connected in star, and adjacent one is segmented inner cylinder
One end is in " L " connected in star；" u "-shaped bell and spigot frame is that " u "-shaped bell and spigot frame including one end is in the segmentation of " u "-shaped groove
Cylinder, one end of adjacent segmentation inner cylinder is in " u "-shaped groove.
Preferably, described steel outer barrel is linked together by flange by multistage segmentation steel cylinder and formed.
Preferably, the flange that described support ring is set for lengthening.
Preferably, the outside of described steel outer barrel is provided with steel tower.
Preferably, described steel outer barrel is integral solder steel cylinder.
Preferably, the outside of described steel outer barrel is provided with armored concrete outer barrel.
Preferably, described support ring is the steel-support ring on steel outer tube inner wall.
The present invention is to utilize steel and fiberglass (FRP) respective advantage, overcomes respective shortcoming, so as to reach structure load-bearing and
Anticorrosion dual purpose, specific feature are as follows：
1) smoke removal facility is a towering structure, is primarily subjected to wind load, earthquake and temperature action, it is necessary to higher structure
Intensity, outer barrel use steel construction, then take full advantage of the characteristics of steel strength is high, easy to process.Inside and outside cylinder organic composite can be real
Now common stress, glass fibre reinforced plastic structure thickness degree is greatly reduced, reduces construction costs.
2) flue gas corrosion is the corrosion under a kind of condition of high temperature, is more difficult to overcome and safeguards compared with general corrosion, and fiberglass
There is good resistivity to the acid of big gas and water and general concentration, alkali, salt and a variety of oils and solvent, be excellent anti-
Corrosion material, it is important channel and the means for solving flue gas corrosion from FRP inner cylinders therefore.But fiberglass modulus of elasticity is relatively low,
Malformation is big, is not suitable for building larger self-supporting chimney.Inside and outside cylinder organic composite can make full use of the intensity of steel outer barrel with
The high advantage of modulus of elasticity, so as to make up the defects of fiberglass modulus of elasticity is low, deformation is big so that the intensity of composite inner barrel is with preventing
Rotten performance performs to optimum state.
3) because using polymeric foamable material, steel cylinder can both organically combined with glass fibre reinforced plastic cylinder, while also ensure two
In the case of cylinder vertical deformation is inconsistent, meets that relative " freedom " deforms, solve fiberglass and the steel coefficient of expansion incomplete one
The problem of cause.
4) compared with independent FRP inner cylinders, compound smoke removal facility of the invention has good heat-insulating property, can reduce cold
The quantity of lime set, and improve atmosphere hoist height.
5) polymeric foamable material density is low, high resilience and adhesive property, when inner/outer tube add up modified difference it is larger when, can
Deformed with release temperature.
The present invention compound smoke evacuation facility structure it is simple, and can common stress, both met structural strength needs, together
When also meet anticorrosion requirement.The compound smoke removal facility of the present invention has good heat-insulating property, it is not necessary to separately sets heat-insulation layer.This
Invention is particularly suitable for existing Steel Inner Core of Chimney transformation, on the premise of existing steel inner cylinder is not removed, reaches anti-corrosion mesh by reusing
, it can largely save construction costs, remarkable in economical benefits.
