Technical field

This utility model relates to a kind of Filter Tuber For Clean Coal burning boiler.

Background technology

At present, the most common numerical control boiler there is problems in that the form that fire bars is water pipe, not only makes trouble And owing to water pipe fire bars and body of heater are welded form, ash discarding cleaning is the most highly difficult；Arranging of flue is single, once wind Machine quits work, and the remaining cigarette in smoke pipe is difficult to drain only, and unburnt coal combustion environments is bad, causes the wasting of resources；Blower fan sets Put the outside at body of heater, not only install complicated but also affect attractive in appearance.

Utility model content

In place of the purpose of this utility model is to avoid the deficiencies in the prior art, it is provided that numerical control Filter Tuber For Clean Coal burning boiler, from And in place of effectively solving the deficiencies in the prior art.

For achieving the above object, the technical scheme that this utility model is taked is: described Filter Tuber For Clean Coal burning boiler, it includes Body of heater, arranges the first combustor, the second combustor and the 3rd combustor being sequentially connected in series in body of heater, the 3rd combustor is with chimney even Connect；Connected by the first by-pass flue between described first combustor and chimney, rotatable in the exit of the first by-pass flue Be provided with the flap for blocking the first by-pass flue；The jointed shaft eccentric setting of flap, under gravity, flap rotates And open described first by-pass flue；It is provided with for by the smoke exhaust fan of flue gas sucking-off in described 3rd combustor in chimney, Described flap is arranged at the air outlet of smoke exhaust fan, and under the wind-force effect of smoke exhaust fan, flap upset is other by described first Smoke uptake blocks.

Further, described first combustor is connected by quirk with described second combustor；Second combustor passes through pipeline It is connected with described 3rd combustor；3rd combustor is provided above drain chamber, and drain chamber is connected with described chimney by pipeline.

Further, combustion chamber and deashing storehouse it are provided with from top to bottom in described first combustor.

Further, described second top of combustion chamber is provided with the second by-pass flue, and described second by-pass flue is by described First by-pass flue connects with described chimney.

Further, the smoke inlet of described first by-pass flue is arranged on the top of described first combustor；Described second is other The entrance of smoke uptake is arranged on the top of described second combustor.

Further, described deashing storehouse and described three-barreled sidewall and bottom are provided with fire-resistant mud layer.

Further, described quirk is vertically arranged, and described second combustor is arranged on the upper left side of described first combustor, institute The entrance stating the second by-pass flue is arranged on the top of described quirk；The porch of the second by-pass flue is provided with deflector, the Liquid in two by-pass flues is through deflector water conservancy diversion the bottom that instills the first combustor through described quirk.

Further, described flap is L-shaped；Flap upper end is relative with the air outlet of described smoke exhaust fan.

Further, the combustion chamber sidewall of described first combustor is provided with coal filling hole；Set above described combustion chamber sidewall It is equipped with wind distributing hole；Circular wind distributing hole it is provided with bottom described deashing storehouse.

Further, above described body of heater, both sides are provided with dismountable baffle plate and numerical control display screen.

Further, described second combustor is provided above the second cleaning door, and described 3rd sidewall of combustion chamber is provided with Three cleaning doors, described drain chamber is provided above the 4th cleaning door.

Further, being provided with integral type fire bars between described combustion chamber and deashing storehouse, described fire bars is the solid knot of casting Structure, fire bars one end is hinged and connected on described body of heater, is provided with upset driving lever below the other end of fire bars, and upset driving lever is rotationally Being arranged on body of heater, upset driving lever one end outside body of heater is provided with handle.

The when of normal operation of boiler, blower fan works, and blower fan blows flap, and flap is by the first by-pass flue and the second bypass Flue is closed, and the connection of the first by-pass flue and the second by-pass flue and chimney disconnects, and it is normal that flue gas enters chimney along drain chamber Discharging, when blower fan quits work when, flap recovers vertical state, the first by-pass flue and second due to the effect of gravity By-pass flue communicates with chimney, owing to not having the remaining cigarette in the sucking action of blower fan, pipeline and combustion chamber to discharge from by-pass flue, Owing to the connector of combustion chamber and the second combustor is in the top of fire bars so that combustion chamber is naturally formed one upwards Air-flow, makes remaining fire coal fully burn, and remaining cigarette is discharged smoothly.

Technique scheme of the present utility model has the advantages that this utility model uses turnover cast-iron stove Bar, not only installs easily manufactured, and is easy to deashing；The structure design of unique by-pass flue, it is ensured that in the unburnt feelings of coal Cutting off blower fan under condition, remaining cigarette can be discharged smoothly, and avoids coal-fired generation detonation.
