Description

The boiler smoke dust-removing desulfurating apparatus

The utility model relates to the flue-gas dust-removing and desulfurization device of boiler, stove.

Boiler smoke is one of primary pollution source of urban air, and northern China city especially is because warming, the all size boiler discharges together, environmental protection to the city forms serious threat, and is therefore extremely important to the dust-removal and desulfurizing of boiler smoke, also relates to the important engineering of environmental protection.Though existing boiler dusting desulfurizer style is a lot, general structure more complicated, cost is more expensive, and mostly is fixed building structure, can't produce in batches in factory.

The purpose of this utility model promptly is at above-mentioned existing in prior technology weak point, comprise complex structure, cost is more expensive, and mostly belong to stationary structure, can't be in the problem of aspects such as factory produces in batches, and provide a kind of simple in structure, low cost, dedusting and desulfurized effect fine, and be convenient to carry out the boiler smoke dust-removing desulfurating apparatus of producing in serial form in factory.

The purpose of this utility model is achieved through the following technical solutions:

A kind of boiler smoke dust-removing desulfurating apparatus, comprise cell body (20), air-introduced machine (1), air inlet pipe (2), blast pipe (9) and chimney (10), in cell body (20), water is housed, and overfall (15) and draining valve (16) are housed at its end, the other end at cell body (20) is equipped with air-introduced machine (1) and air inlet pipe (2), air inlet pipe (2) elbow is downward, and kink one impulse device (4), in the both sides of impulse device (4) float (3) is housed; Sparge pipe (7) is housed on air inlet pipe (2), immersible pump (6) is housed in cell body (20) bottom and links to each other with sparge pipe (7) by pipeline; Absorption net (8) and feed pipe (19) are housed on sparge pipe (7); Blast pipe (9) and chimney (10) are housed at the top of cell body (20), and the downside at the top is equipped with shoot door (18), locates to have one partition wall (11) downwards at shoot door (18).The bottom of impulse device (4) is a bell-mouthed shape, and at the horn mouth place a conical air deflector (5) is housed.The top of air deflector (5) is zigzag.In the elbow of air inlet pipe (2) annular spray pipe (13) is housed also.In the bottom of cell body (20) sewage pump (17) is housed also.

The utlity model has following advantage and effect:

This deduster belongs to wet turbid deduster, utilizes impulse, spray, absorption 3-stage dust-removal mechanism, is provided with the impulse water surface, hydroecium, air chamber, pressurization shower flue dust, absorption net in deduster inside:

1. after flue gas entered deduster by Thermal Equipments such as boilers by air-introduced machine outlet, the waste gas that has a flue dust is the impulse water surface from top to bottom, and wetting flue dust strengthens trickle grit weight, makes it to fall into the collection ashpit, has finished dedusting first.

2. form the second road cleaner on deduster top via immersible pump, jet pipe, the flue dust that rises is carried out secondary spraying from top to bottom, increase trickle grit weight once more, in the process of dedusting, sulfur in smoke is water-soluble, generate the droplet of sulfurous acid, and from flue gas, separate, finished final dusting with grit.

3. the deduster top is provided with corrosion resistant performance good adsorption net, the minimum smokeshade of residue is adsorbed once more captures, and finishes third dedusting.

Behind twice desulfurization, third dedusting, the flue gas that purifies is discharged deduster, enter atmosphere, reached good dust-removal and desulfurizing effect, and it is long to have a life-span, the impulse system adopts float automatic control and adjustment water surface distance, cycling use of water, water consumption is little, and air-introduced machine is before deduster, overcome the advantage of aspects such as air-introduced machine band water, be applicable to various industry, heating boiler, Industrial Stoves and the smoke abatement and dust control of concentrating the various large-scale diet brick kitchen range of discharging waste gas flue dust in a organized way.

Boiler smoke dust-removing desulfurating apparatus of the present utility model can carry out seriation in factory and produce in batches, the specification that it has various difformities and a size to be adapting to the different needs of different boilers and kiln, and with boiler, supporting, the on-the-spot assembling of kiln (comprising on the ground and the installation of under ground portion).When adopting this dust-removing desulfurating apparatus, whirlwind or rough filtering device should be arranged to alleviate this dust-removing desulfurating apparatus dedust burden in the flue front portion of boiler or kiln, be convenient to obtain better effect.
