Description
Technical field
The present invention relates to a kind of special composite material and application thereof, relate in particular to it and remove application in the equipment of the oxysulfide in the flue gas of boiler emission, also relate to the manufacture method of this equipment in preparation.
Background technology
With coal or oil is that a large amount of flue gases are discharged in the boiler or the fuel-burning power plant of fuel.These flue gases contain objectionable impuritiess such as SOx, NOx, HCl and HF, and wherein SOx is the essential substance that forms acid rain.With the difference of burning coal, SO
2Content is usually at 300-5000ppmv (1000-15000mg/Nm
3) between.But exhaust gas volumn is very huge, and the opinion with coal firing boiler, steam scale are from 35T/h to 2500T/h, and generating set capacity 6MW is to 1000MW, and exhaust gas volumn is by 50,000 Nm
3/ h to 250 ten thousand Nm
3, SO
21000 tons/year to 100,000 tons/year of quantity dischargeds.Because SO
2Be sour gas, adopt alkaline aqueous solution except that the SOx in the smoking gas, i.e. (Flue Gas Desulfurization FGD) is effective means to smoke-discharging sulfur-removing, or flue gas desulfurization, is with a wide range of applications.
The method of flue gas desulfurization is more, according to the difference of the raw material that is adopted, mainly contains following several:
With the Wingdale is the calcium method of raw material, generates gypsum, can be used as the building materials raw material;
With ammonia is the ammonia process of raw material, generates the sulphur ammonium, can be used as chemical fertilizer raw material;
With magnesium oxide is the magnesium method of raw material, generates sal epsom, and purposes is little;
With yellow soda ash or sodium hydroxide is the sodium method of raw material, generates sodium sulfate, and purposes is little.
These methods respectively have its adaptability and relative merits.But they have any is identical, is exactly the desulfurizing tower that all has a structural similitude, or claims thionizer.Desulfurizing tower is a very typical gas-liquid mass transfer (contact) equipment.In technical field of chemical engineering, be called the chemical absorption tower, the solute in the gas phase (pollutent is such as sulfurous gas etc.) is dissolved in the liquid phase, with the alkaline absorbent generation chemical reaction in the liquid phase, is transformed into a kind of new material.
At chemical field, the general absorption tower form of at first selecting is a packing tower, and the gas-liquid mass transfer surface is provided by filling surface, and next adopts the tray column structure, and the gas-liquid mass transfer surface is the foam surface that the gas bubbling forms.These two kinds of turriforms are suitable for clean system, such as not containing solid and being difficult for the system that obstruction takes place structure.For process such as flue gas desulfurization, no matter above which kind of method, all exist easy blocking problem, not because dust contained flue gas, be exactly that intermediate product is insoluble, final product crystallization etc. because raw material is insoluble, thereby the packing tower of widespread use and board-like tower are difficult to adapt to flue gas desulfurization course in general chemical process.
For smoke exhaust and desulfurizing tower, or be called the oxysulfide absorption tower, can be called thionizer yet, general all preferential selection does not have the atomisation tower of filler, or is called spray column.On the other hand, because boiler fuel flow is very huge, such as a 600MW unit, its boiler fuel flow can reach 2,200,000 Nm
3/ h, the diameter of its desulfurizing tower reaches 16m.Therefore, the flue gas desulfurizing tower is a kind of typical large-scale spray column.
In the prior art, a typical desulfurizing tower can both be realized three steps of desulfurization simultaneously: i.e. SO
2Absorb sulfite oxidation and sulphate crystal.At SO
2When absorbing, also be accompanied by other pollution substances in the flue gas, such as SO
3, NO
2, HF, the absorption of HCl is generated as corresponding salt respectively, is dissolved in the absorption liquid, and the flue dust in the flue gas also is absorbed liquid and washs, and is blended in the absorption liquid.Therefore contain vitriol in the absorption liquid, muriate, fluorochemical, the solid matter of abradability in addition with high corrosion.With the ammonia process is example, and sulphate content can reach more than 50% in the absorption liquid solution, and ammonium chloride content can reach more than 30%, and wherein solid content can be more than 20%.Even more serious is, flue gas and aqueous solution absorption agent droplet, and high speed moment contact contains SO
3High-temperature flue gas in desulfurizing tower by chilling, can form sulfuric acid mist, and then produce dilute sulphuric acid, show serious corrosion.
Therefore, a subject matter of restriction flue gas sulfur removal technology development is exactly how to overcome the protection against corrosion of large-scale spraying desulfurizing tower and make difficulty.
Although prior art also has some measures, such as, adopt high-grade alloy steel and adopt Steel Lining rubber or resin glass flake paint etc.,, not because the unusual expensive widespread usage that is difficult to of price becomes unreliable because of the difficulty that construction is made exactly.What present most desulfurizing device adopted is the method for steel lining resin glass flake paint, still, because the start-stop car is frequent, with reasons such as constructions, the phenomenon that dope layer is easy to come off occurred, caused the desulfurizing device nucleus equipment can not be normally and life-time service, must improve.
