Description
Technical field:
The utility model relates to the wet dust removal desulphurization device of Industrial Boiler, is specifically related to a kind of independent ability of swimming dust-removing desulfurizing device that divides.
Background technology:
At present, it is wet dedusting desulfurization that the Industrial Boiler flue-gas dust-removing and desulfurization uses the most general method, the basic process of wet dedusting desulfurization is with desulfurizing agent solution washing flue gas in desulfurization reaction tower, make both that strong chemical reaction take place, remove dust and sulfide in the flue dust, reach the effect that purifies flue gas.Existing industrial wet method sulphur removing and dust removing device can be divided into two big classes: a class split type hydrofilter that to be dedusting separate with desulfurization; Another kind of is the integral type wet dust removal desulfurizer that deduster and devulcanizer combine.
Split type wet desulphurization device has two kinds: a kind of is that the whirlwind multi-tube dust cleaner increases spray expansion chamber dust-removal and desulfurizing method; Another kind is that multi-tube dust cleaner adds spray chamber dust-removal and desulfurizing method.
The whirlwind multi-tube dust cleaner increases water-bath expansion chamber doctor treatment, boiler smoke at first enters multi-tube dust cleaner and carries out dry dust removal, send into the desulfurization of water-bath expansion chamber through the flue gas behind the one-time dedusting by air-introduced machine, flue gas enters chimney behind water bath desulfurization in the water-bath expansion chamber, its shortcoming is: floor space is big, need enough places to arrange expansion chamber, water level control simultaneously is difficult, resistance is too big when water level is high, cause the boiler operation under positive pressure, when water level is low, cause the invalid or desulfurized effect of desulfurization not reach higher standard;
Multi-tube dust cleaner increases the spray type desulphurization method and is meant that the flue gas of boiler is earlier through multi-tube dust cleaner, flue gas after the dedusting enters devulcanizer through flue, flue gas in devulcanizer desulfurization after air-introduced machine enters chimney, its shortcoming is that floor space is big, it is many that multi-tube dust cleaner adds desulfurizer rear pass elbow, the resistance of ducting is big, need to increase air-introduced machine power, to move towards consistent flue gas with water serious because of desulfurization water injector and flue gas, corrosion air-introduced machine and chimney, sticky particles in the flue gas is bonded in the hard attachment of formation on the draught fan impeller, causes the impeller disequilibrium, normal operation that can not be long-term continuously.
Existing integral type wet dust removal desulfurizer is, dedusting and desulfurization are carried out in same container, and desulfurization water and dirt are discharged from sewage draining exit simultaneously.The integral type wet dust removal desulfurizer can be divided into two big classes: a class is common gallet water curtain dust collector, this deduster floor space is big, installation period is long, after the deduster desulfurization, the flue gas moisture content is difficult to control, overflow water causes secondary pollution easily, and sedimentation basin floor space serious disease need be equipped with the dirty equipment that drags for; Another kind of is the wet dedusting disconnector of steel, its shortcoming is that sulfide in the flue gas and desulfurizing agent react that a small amount of sulfuric acid of generating or the dust-laden particle in sulfurous acid and sulfate or sulphite and the flue gas are big to the corrosivity of steel, service life short, and it is big that draining accounts for area.Desulfurization water once uses (the also reusable edible that has), and overflow water easily causes secondary pollution, and the pH value of desulfurization water is difficult to regulate, by the blowdown of artificial interruption, the operational effect fluctuations is big, can not stablize to reach desulfurized effect, and smoke discharging is moisture, can corrode air-introduced machine and flue.
Therefore, still there is the problem to the seriously corroded of deduster housing and air-introduced machine in existing wet dust removal desulfurizer, has that floor space is big, water consumption is big, the unsettled shortcoming of dust-removal and desulfurizing effect.
The utility model content:
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of independent ability of swimming dust-removing desulfurizing device that divides, and has solved the problem to deduster housing seriously corroded, has that floor space is little, water consumption is few, the advantage of dust-removal and desulfurizing effect stability.
In order to achieve the above object, the technical scheme taked of the utility model is:
