Abstract
A wet desulphurizing and dust-removing device relates to an improvement on a dust remover structure in a boiler flue and solves the problem that the conventional dust remover has poor dust-removing and desulphurizing effects. The wet desulphurizing and dust-removing device mainly comprises a water pool body, a barrel body, a guide apparatus, a flue gas inlet pipe, a spraying water pipe and the like, wherein the spraying water pipe is arranged at the throat part of a Venturi tube; the guide apparatus is made into a fan-shaped inclined columnar passage; and the direction of the fan-shaped inclined columnar passage of the guide apparatus is consistent with the rotating direction of a flue gas outlet. The wet desulphurizing and dust-removing device has the advantages of obvious dust-removing and desulphurizing effects and no secondary dust pollution and can be extensively applied to the boiler flue as a dust-removing and desulphurizing device.
Description
Technical field
The utility model is that the wet type desulfurizing dust collector after the improvement is used for boiler flue flue gas is carried out desulfurization and dedusting to the improvement of existing desulfurizing dust-collector structure.
Background technology
Its soot dust granule aggegation sedimentation of employed dust arrester is relatively poor in boiler flue at present, and negative pressure when operation fan belt water has a strong impact on service life of blower fan, and its cone-shaped dust collecting box liquid level is wayward, and flue dust clean-up effect again is relatively poor.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides a kind of dedusting, the tangible wet type desulfurizing dust collector of desulfurized effect.
The purpose of this utility model is achieved through the following technical solutions: wet type desulfurizing dust collector, comprise the pond body, upper port at the pond body is installed the deduster cylindrical shell, cylindrical shell is suitable for reading to link to each other with the scroll casing shape smoke-intake pipe with flange, guider is packed in the bottom of cylindrical shell, cylindrical shell suitable for reading with guider in link to each other with Venturi tube between the mother rib lateral rotundum, it is suitable for reading that smoke-intake pipe is installed in the Venturi tube of cylindrical shell, on cylindrical shell, be manufactured with outlet flue, dewatering plate, the maintenance manhole, it is characterized in that: in smoke-intake pipe and Venturi tube, spray header is installed, spray head is positioned at the throat of Venturi tube, guider is made fan-shaped batter post passage, and the fan-shaped batter post channel direction of guider and the rotation direction of outlet flue are consistent.
The beneficial effects of the utility model: the utility model adopts said structure, owing to adopted spray header at the aditus laryngis position of Venturi tube, the water droplet that rotates into Venturi tube and spray header ejection at a high speed when the flue gas of dust-laden collides the dust that makes in the ash-laden gas and sulfide and is adsorbed and is attached in the water; When air-flow and water were gone out in by Venturi tube, because speed slows down, under gravity and action of inertia, the mixture of a part of water and flue dust etc. fell into the pond, below, finishes dedusting for the first time.When the fan-shaped batter post passage of crossing guider when air communication rises, under the effect of guider, the air-flow rotation is risen, because action of centrifugal force, the moisture content of remnants and the mixture of flue dust are thrown on the cylinder inboard wall in the air-flow, under the effect of dewatering plate, water is blocked again along barrel and flows into the pond, finishes dedusting for the second time.Its advantage is that the effect of dedusting, desulfurization is obvious, and water content not in the flue gas behind the dust-removal and desulfurizing does not produce corrosion to blower fan, prolongs blower fan service life.

The specific embodiment
Wet type desulfurizing dust collector mainly is made of pond body 1, cylindrical shell 6, guider 2, Venturi tube 4, smoke-intake pipe 10, water inlet shower 7 etc.Pond body 1 is generally used cement masonry, by water-level control apparatus 11, sedimentation basin 12, neutralization pond 13, clear water reserviors 14 constitute, in pond body 1 upper port deduster cylindrical shell 6 is installed, on cylindrical shell 6, produce mouth 8, dewatering plate 5, inspection manhole 3, guider 2 is packed in the bottom of cylindrical shell 6, fan-shaped batter post passage by guider 2 outsides guarantees to communicate up and down, cylindrical shell 6 suitable for reading with guider 2 in link to each other with Venturi tube 4 between the mother rib lateral rotundums, cylindrical shell is suitable for reading to link to each other with scroll casing shape smoke-intake pipe 10 with flange 9, on smoke-intake pipe 10, be fixed with into water shower 7, guarantee that its spray head is positioned at the throat of Venturi tube 4, the rotation direction of smoke-intake pipe 10 wherein, the fan-shaped batter post channel direction of guider 2, the rotation direction of outlet flue 8 must be consistent, to guarantee the direction of rotation unanimity of air-flow.
The working procedure of desulfurizing dust-collector is: swiftly flowing flue gas is when smoke-intake pipe enters into Venturi tube, under the effect of smoke-intake pipe, flue gas rotates at a high speed, in of the water droplet collision of Venturi tube throat flue gas with the ejection of water inlet shower, produce the heating power cohesion simultaneously, dust in the flue gas and sulfide are adsorbed to be attached in the water, when flue gas when the Venturi tube bottom is gone out, it is big that the space becomes suddenly, flue gas flow rate reduces suddenly, under gravity and action of inertia, part water falls into the pond, below, take away a part of dust and sulfide, when flue gas when guider passes through, the fan-shaped batter post passage of guider improves the rotary speed of flue gas, flue gas rotates rising at a high speed, under action of centrifugal force, remaining moisture content is thrown to the outside in the flue gas, and under the effect of the dewatering plate that cylinder inboard wall is installed, the water that will contain dust and sulfide touches down the back and flows into the pond, below along cylinder inboard wall, discharge through the outlet flue of flue gas on cylindrical shell after final dusting and the dehydration, desulfurized effect is 70%～80% in the flue gas of discharging, and dust removing effects is up to more than 95%, and flue gas is not with water to discharge simultaneously, do not corrode blower fan, can prolong the service life of blower fan.The water that contains dust and sulfide in the pond can be recycled after handling through sedimentation basin, neutralization pond.
