5, according to 4; Do the wet desulfurization integrated efficient smoke eliminator of dedusting; It is characterized in that self-excitation boiling-house (16), flue gas impacts the boiling effect through the doctor solution that rushes at the bottom of self-excitation boiling-house and the tower of venturi fore shaft explosion type, and sulfur-containing smoke gas is thoroughly removed.
6, according to 5; Do the wet desulfurization integrated efficient smoke eliminator of dedusting; It is characterized in that devulcanizer (17) retaining ring (18) moisture trap (21) in the desulfurizing tower; After flue gas thoroughly removed sulphur through devulcanizer, air water rose by retaining ring and moisture trap separated form water to be come out, and flue gas is sent into chimney by air-introduced machine and discharged.
Technical field:
A kind of dried dedusting of the present invention desulfurization integrated efficient smoke eliminator that wets relates to dust-removal and desulfurizing, gas cleaning, the association area of energy-saving and emission-reduction industry.
Technical background:
The dust-removing desulfurating apparatus of domestic production at present, simple in structure, performance is single, or not desulfurization of dedusting; Or not dedusting of desulfurization, both are not well merged, as mechanical deduster, filtration dust catcher; Sack cleaner, electric cleaner, all effectively desulfurization; And the wet type desulfurizing tower of China's production at present has granite (numb stone) dedusting and desulfurizing tower, the unidirectional spraying and dedusting desulfurizing tower of the bitubular; Products such as cyclone wet-type dedusting and desulfurizing tower; Its principle all is dust in flue gas to be rushed in device bottom by the doctor solution spray flow into circulating water pool, causes circulating water pool ash quarrel to pile up, and nozzle is stopped up by the ash quarrel easily when using recirculated water; Have influence on the normal operation of equipment, main cause is that smoke dust does not cause through effective dedusting.
Summary of the invention:
To above-mentioned situation; The purpose that the present invention does the wet desulfurization integrated efficient smoke eliminator of dedusting is for the user a kind of suitable coal in China quality and existing boiler to be provided; The industrial furnace combustion requirements is not stopped up the dust-removal and desulfurizing equipment that dust-removal and desulfurizing equipment nozzle damages spray system again.It is rational in infrastructure, compact in design, and processing ease, working service is convenient, and energy savings cuts down the consumption of energy, and high emission reduction efficiency is arranged.In order to realize above-mentioned target, a kind of dried dedusting desulfurization integrated efficient smoke eliminator that wets, it is made up of the dry type cyclone dust collectors of transforming a kind of advanced person in back and most effective wet type venturi desulfurizing tower.At first be the reasonability of its structure, two matched are accomplished dedusting separately; The desulfurization task has solved the problem of not desulfurization of dry collector, and it is not thorough to have solved the wet scrubber dedusting again; Can not dust be proposed, the ash quarrel flows into circulating water pool, causes spray nozzle clogging to influence the problem of desulfurized effect.In cyclone dust collectors, transform, adopt imitative pottery body deduster core arrangement, set up deflector advancing mouth; And below the flue gas expansion chamber, set up ash bucket, and in inner canister, set up cyclone, make flue gas get into deflector behind expansion chamber from inlet; Dust slowly falls into ash bucket, and the flue gas after the dedusting rises under the effect of air-introduced machine and walks flue gas passageway entering wet type desulfurizing tower from inner canister; The mouth that advances of the exhanst gas outlet of dry collector and wet type desulfurizing tower is linked to be an exhaust gases passes, and flue gas is concentrated under the spray washing at high pressure through the spray chamber of passage to the wet type desulfurizing tower; Flue gas and doctor solution hybrid reaction, through the venturi fore shaft time, the further mixed film friction impact of flue gas and doctor solution; Overwhelming majority sulfur dioxide are removed, flue gas and doctor solution explosion type pass through the venturi fore shaft, get into doctor solution generation self-excitation at the bottom of self-excitation boiling-house and the tower effect of seething with excitement; Sulfur dioxide is thoroughly removed totally, and sewage flows into water seal tank from overfall, arrives circulating water pool again; Sulfur dioxide becomes gypsum through acid-base reaction, and alkaline doctor solution continues to recycle.Flue gas behind the dust-removal and desulfurizing slowly rises, and gets into moisture trap through the retaining ring outlet flue, discharges from chimney through air-introduced machine.Because this device is the composite set of a kind of dry collector and wet type desulfurizing tower; Its effect is superior to any deduster or desulfurizing tower; And be that the user is installed higher sack cleaner of price or electric cleaner etc. additional before desulfurizing tower is installed, reduced by 50% fund.This device applicability is good, to chemical industry, and metallurgy, iron and steel, boiler such as power plant and Industrial Stoves are very suitable.
