Gaseous mixture is after the purification of sack cleaner 32, and exit gas dustiness controls at 20mg/Nm
3below, directly can be sent to chimney 40 qualified discharge by neat stress pipeline 39, or fluidized bed dryer in drying workshop dry and after through smoke stack emission.The gaseous mixture flowed out from mixing chamber 21 gas outlet also first can send drying plant 38 to heat furnace charge and reclaim heat, then enters air by chimney 40 after work feed bag dust collector 32 dedusting.
Consider the inhomogeneities of the air-distribution entered by flue arm, it is not thorough that the local carbon distribution that air mass flow is little may burn, and needs to carry out local by travelling burner 12 and burn carbon distribution operation.
The technical process of the present embodiment is as follows:
Before burning carbon distribution, the prolonging combustion phase burns the stove time, and the temperature in fire grate region is increased to after more than 750 DEG C, stops burning stove and proceeds to the operation of burning carbon distribution;
Close heating furnace gas-fired valve 17, air burning valve 2, hot gas export valve 3, cold gas inlet valve 4 and chimney valve 5; Open flue arm air intake pipeline control valve 6, burn carbon distribution exhanst gas outlet pipeline stop valve 16 and mixing chamber air intake pipeline control valve 20, start dedusting fan 37, open dedusting fan entrance stop valve 35 and dedusting fan outlet stop valve 36; Under the effect of dedusting fan 37 draft, combustion air enters carbon distribution coking district 13 below fire grate by flue air intake pipeline 7, takes fire after air is met in the carbon distribution coking in this region, until burn completely, burns the carbon distribution end of job;
The flue gas that carbon distribution burning produces burns carbon distribution exhanst gas outlet pipeline 15 through heating furnace and enters flue gas air mixing chamber 21, and flue gas air Mixture flows to sack cleaner 32 through mixed gas outlet pipeline 23; Detected temperatures when mixing chamber outlet point for measuring temperature 22, if temperature is more than 200 DEG C, then open secondary air registers valve 24 and be again mixed into air, and at point for measuring temperature 25 thermometric again thereafter, regulate the aperture of secondary air registers valve 24 according to the temperature value recorded, ensure that the mist temperature entering sack cleaner 32 is lower than 200 DEG C;
Mist is after sack cleaner 32 dedusting, and the dry also recovery waste heat of drying workshop 38 fluidized bed dryer, then enters air by chimney 40;
After burning carbon distribution operation, reverse gas cleaning is carried out to cloth bag, now, close flue arm air intake pipeline control valve 6, burn carbon distribution exhanst gas outlet pipeline stop valve 16, mixing chamber air intake pipeline control valve 20 and secondary air registers valve 24, open blowback nitrogen pipeline stop valve 28, pulsed nitrogen enters inside cloth bag and is blown off by the sticky object of cloth bag outer surface, and sticky object falls into the ash bucket 30 below sack cleaner 32; When cloth bag entrance is with when exporting pressure reduction lower than setting value, reverse gas cleaning terminates; Dedusting ash adopts suction vehicle 31 or pneumatic conveying mode to deliver to user's point.
When adopting travelling burner 12 cooperation to carry out partial combustion, burner 12 is aimed at carbon distribution residual region, connects electronic lighter, open burner air inlet valve 11 and burner gas entry valve 9, air and coal gas export mixed combustion at burner 12, by the residual carbon distribution scaling loss in its front.
