Description
Technical field
The present invention relates to a kind of spray deduster, particularly a kind of deduster for burning boiler.
Background technology
Can produce a large amount of dust and particle after boiler combustion, after generally all will carrying out dedusting by deduster, just can drain in air, but existing deduster kind is a lot, as: sack cleaner, wet scrubber etc.Wherein sack cleaner is generally used for elementary dedusting, and dust collection capacity is general, and energy consumption is large simultaneously, and physical life is short; Existing boiler many employings wet scrubber, by arranging air-introduced machine and axial flow air inducing fan at the both ends of smoke dust duct, spray port is arranged between the two, flue dust in body of heater is drained to smoke dust duct by axial flow air inducing fan, spray port carries out water spray makes water fully be combined with flue dust, go into sewage, enter in cesspool; In this process, under the effect of air-introduced machine, by contacting with spray port after axial flow air inducing fan, generally can there is flue dust flowing fast in flue dust, spray port water spray is insufficient, greatly reduces overall dust removing effects.
Summary of the invention
For the deficiency existed in background technology, the object of the invention is to provide a kind of spray deduster, can solve flue dust flow velocity in prior art too fast, spray insufficient cause dust removing effects difference problem.Adopt the present invention to realize high-effective dust-removing, structure is simple, cost of manufacture is low.
For achieving the above object, the invention provides following technical scheme: a kind of spray deduster; Comprise deduster body of heater, cesspool, spray thrower, fan and air-introduced machine, body of heater comprises flue dust import, flue dust outlet and bottom outlet of sewer, and flue dust import is connected to combustion furnace, and flue dust outlet is connected to air-introduced machine; It is characterized in that: the dedusting passage arranging liner type in described deduster body of heater, flue dust outlet is arranged at the upper end of dedusting passage, forms smoke dust duct between dedusting passage and body of heater; Arrange smoke collecting device in dedusting passage, smoke collecting device is fanned by setting up and down and that direction blade is contrary two axial flow air inducing and is formed, and forms the flue dust stagnant wake of convection current between the two; The spray direction of spray thrower perpendicular to dedusting passage and its position higher than smoke collecting device; The bottom outlet of sewer fluid-tight of body of heater is in cesspool.
The present invention is also set to further: the axial flow air inducing of described smoke collecting device fan comprises the upper end axial flow air inducing fan of downward air inducing and the lower end axial flow air inducing fan of upwards air inducing.
The present invention is also set to further: described dedusting channel center position arranges stationary pipes, and stationary pipes is connected to external water source and is communicated in spray thrower, and two axial flow air inducing fans are fixed in stationary pipes.
The present invention is also set to further: described stationary pipes is installed at least one spray thrower, and spray thrower is arranged on the upper end of upper end axial flow air inducing fan.
The present invention is also set to further: described spray thrower is loop shaped, and side is arranged multiple nozzle.
The present invention is also set to further: described flue dust import to be arranged on body of heater and to be communicated in the upper end of smoke dust duct.
The present invention is also set to further: described stationary pipes accesses from the bottom of body of heater.
Beneficial effect of the present invention:
By arranging the dedusting passage of liner type, when not increasing body of heater volume, the path of smoke dust duct can be increased, in time the flue dust in body of heater being concentrated and causing in dedusting passage, the axial flow air inducing fan that two air inducing directions are contrary is set in dedusting passage, two axial flow air inducing fans are in the process of rotating, flue dust stagnant wake is formed in passage between, concentrate on flue dust in dedusting passage after the air inducing fanned through lower end axial flow air inducing, enter flue dust stagnant wake, flue gas is under the effect that upper end axial flow air inducing is fanned and lower end axial flow air inducing is fanned, rest in flue dust stagnant wake, now spray thrower water outlet sprays, concentrated spraying and dedusting is carried out to the flue dust of flue dust stagnant wake, now water spray fully can contact with the dust granules in flue dust, then outlet of sewer is fallen to, enter cesspool, improve efficiency of dust collection, outlet of sewer fluid-tight, in cesspool, prevents flue dust from discharging from outlet of sewer thus leaking.
In dedusting passage, center arranges stationary pipes, and spray thrower and axial flow air inducing fan are arranged in stationary pipes, make overall structure compacter, is convenient to install and maintenance; Spray thrower is loop shaped and socket is arranged in stationary pipes, and the side of spray thrower arranges multiple nozzle, and water spray is fully contacted with flue dust.
