Description
Technical field
The utility model provides binary channel boiler flue gas dust remover used in filed of flue gas purification.
Background technology
The fuel such as currently used coal, coke, although in process of production by processing, but still may be residual containing a small amount of sulphur
Stay, can be spread in combustion in the form of sulphur oxide gas or dust in atmosphere, form acid rain, dust etc. and cause ring
Pollute in border；In addition, during the fuel combustions such as coal, coke, ash can be formed and graded residue, part of ash can be with little particle
The form of dust is disseminated in air, causes environmental pollution.Therefore, a kind of smoke desulfurizing dust-remover for boiler of design, suppression coal,
Pollution of the fuel such as coke to air is very necessary.

Connect, in the first dust storage chamber built with first liquid level gauge, and cinder notch is removed provided with first, the first blowdown is provided with the first dust storage chamber side
Mouthful, return duct bottom is connected with the first dust storage chamber top equipped with the first spray equipment；
Second spray equipment is housed, the backflow flow tube head end equipped with the second spray equipment is inserted into the second dust on return duct
Interior, in the second dust storage chamber built with second liquid level gauge, and removes cinder notch, side is provided with the second sewage draining exit provided with second；
Induced duct is connected with the second dust storage chamber upper end, induced duct is arranged on one end of the second frequency conversion fan, frequency conversion fan
The other end is connected with smoke exhaust pipe.
Drawing triple valve is housed between smoke pipe and return duct.
A storage tank is set to be used as anti-down cucurbitula before fume treatment pond.
Return duct head end and tail end are inverted infundibulate.
First dust storage chamber and the second dust storage chamber are fume treatment pond.
Good effect, the utility model noise is small, heat energy is not lost in, power saving, save coal, energy-conservation more than 70%.Suitable conduct
Dust removing device for flue gas of boiler application.

Embodiment
According to the figure, boiler 1 burning produce fume gases through drawing smoke pipe 2, the first frequency conversion fan 3 and smoke-intake pipe 4 with
First dust storage chamber 5 is connected, in the first dust storage chamber built with first liquid level gauge 6, and removes cinder notch 7 provided with first, in the first dust storage chamber
Side is provided with the first sewage draining exit 8, and the bottom of return duct 10 is connected with the first dust storage chamber top equipped with the first spray equipment 9；
Second spray equipment 12 is housed, the backflow flow tube head end equipped with the second spray equipment is inserted into the second collection on return duct
In dirt room 14, in the second dust storage chamber built with second liquid level gauge 13, and cinder notch 15 is removed provided with second, side is provided with the second sewage draining exit
16；
Induced duct 18 is connected with the second dust storage chamber upper end, induced duct is arranged on one end of the second frequency conversion fan 17, frequency conversion
The blower fan other end is connected with smoke exhaust pipe 19.
Drawing triple valve 11 is housed between smoke pipe and return duct.
A storage tank is set to be used as anti-down cucurbitula before fume treatment pond.
Return duct head end and tail end are inverted infundibulate.
First dust storage chamber and the second dust storage chamber are fume treatment pond.
Utility model works process：
The flue gas that boiler combustion is produced carries flue dust, and flue dust is blown into the by drawing smoke pipe in the presence of frequency conversion fan
In one dust storage chamber, air-flow is risen by return duct, and ascending air is contacted in the presence of the first spray equipment with buck, makes dust
Humidifying, is dropped in the first dust storage chamber, in the first dust storage chamber built with alkali lye, and desulfurization, the cigarette of formation are carried out while dedusting
Dirt is deposited in dust storage chamber, periodically removes sediment, and can be discharged while sewage draining exit carries out liquid with flue dust, is now the
One section of dedusting.
Flue gas by first paragraph dedusting is by return duct in the presence of the second spray equipment, and continuation is removed to flue dust
Dirt, while cooled flue gas, produced flue dust is concentrated in the second dust storage chamber, also can periodically be discharged, by second of dedusting
Clean flue gas in the presence of the second frequency conversion fan, air is discharged into by smoke exhaust pipe, this section be second segment dedusting.
The utility model can be also used alone one section of dust arrester and be carried out dedusting using two sections of two-way dedustings.
When second segment dedusting is used alone, triple valve is opened, the flue gas that boiler combustion is produced is directly entered the second spray
Device, by being contacted with alkali lye, realizes the purpose of dedusting and desulfurization, flue gas can directly be passed through into smoke evacuation by second segment dedusting
Pipe is discharged into air.
Depending on selecting two step dedustings or a step dedusting then according to boiler combustion fuel.
