Abstract

The utility model relates to a dedusting and desulfurizing apparatus for flue gas, particularly a high-performance dedusting and desulfurizing apparatus for flue gas; an inertial settling chamber, a ceramic multi-pipe deduster, a draught fan and a wet spraying desulfurizing deduster are orderly connected in series between a flue gas source to be dedusted and desulfurized and a discharge chimney through a communicating pipeline. Wet flue gas after desulphurized can not pass the draught fan, so that the service life of the draught fan can be increased; simultaneously, water quantity in the spraying and desulfurizing process is free from the restriction of the draught fan; the spraying quantity is enlarged; thereby, the desulfurizing and the dedusting effects can be increased. A spray head apparatus in a spraying desulfurizing apparatus is made of glass, so that the corrosion resistant property is better; thereby, the service life is extended, and the operating cost is reduced.

Description

Efficient flue-gas dust-removing and desulfurization device

The utility model relates to a kind of flue-gas dust-removing and desulfurization device, especially a kind of efficient flue-gas dust-removing and desulfurization device.

At present, using in the society and make in the flue-gas dust-removing and desulfurization device many kinds are arranged, as sack cleaner, ceramic multicyclone, electrostatic precipitator, hydrofilter etc.Though existing various simple duster has certain dust removing effects and has characteristics simple in structure, low cost of manufacture, but its dust removing effects is poor, not reaching the dedusting standard is the unsurmountable defective of its existence, existing comparatively advanced dust arrester is with ceramic multicyclone dust collector and wet desulphurization is combined or wet desulphurization and electrostatic precipitation are combined, though this class dust-removing desulfurating apparatus has dust-removal and desulfurizing effect preferably, but have the manufacturing cost height, operating cost is big, the defective that should not popularize; In addition, this class dust-removing desulfurating apparatus mostly is that wet desulphurization is arranged on before the air inducing, and flue gas moist in running easily causes damage to air-introduced machine, reduces its service life, and this is another unsurmountable defective of its existence.

The purpose of this utility model is to provide a kind of simple in structure, low cost of manufacture, it is universal to be suitable for, dust-removal and desulfurizing is effective, the novel flue-gas dust-removing and desulfurization device of long service life.

The purpose of this utility model is achieved in that it comprises inertial settling chamber, ceramic multicyclone dust collector, air-introduced machine, wet dust removal desulfurizer, it is characterized in that being connected in series with inertial settling chamber, ceramic multicyclone dust collector, air-introduced machine and wet spray desulfurizing dust-collector by connecting pipe successively between by the flue gas source of dust-removal and desulfurizing and blowdown stack.Described inertial settling chamber is that a side is provided with into mouth in the top, sidewall in the top is provided with outlet flue, in it advances cabinets cavity between mouth and the outlet flue, be vertically installed with barrier plate, be provided with the box inertial settling chamber of the ash bucket that has the hyoplastron unloading valve in its lower end; Described air-introduced machine is to be connected between ceramic multicyclone dust collector and the wet dust removal desulfurizer by connecting pipe; Shower nozzle in the described wet dust removal desulfurizer is the glass shower nozzle with the circulation pipe threaded engagement, and is provided with glass neck at the downside of glass shower nozzle.

Owing to taked such scheme, the utlity model has following evident characteristic: the one, owing to before ceramic multicyclone dust collector, installed the inertial settling chamber additional, the sectional area of flow of flue gas increases when flue gas enters in the expansion chamber, flue gas flow rate diminishes, and under the effect of barrier plate, change its flow direction, coarse granule is under its action of inertia in the flue gas, thereby fall into the task that ash bucket is realized first order dedusting, after entering ceramic multicyclone dust collector, the flue gas after the dedusting first time alleviated its live load and wearing and tearing, so improved its dust removing effects and increased its service life, thereby overcome the defective that prior art is existed as first order dedusting by ceramic multicyclone dust collector; The 2nd, the wet spray devulcanizer is arranged on after the air inducing, moist flue gas behind the spraying desulfurization and dedusting directly enters chimney, so the moist flue gas after desulfurization is without air-introduced machine, so service life of having improved air-introduced machine, the water yield in the sweetening process of spraying simultaneously is not subjected to the restriction of air-introduced machine, strengthen spray amount, thereby improved the desulfurization and dedusting effect; The 3rd, the ejecting device in the spraying devulcanizer is a glass material, so corrosion resistance is better, thereby has improved its service life, has reduced operating cost.
