Description
Technical field
This utility model belongs to pulverized-coal fired boiler lime-ash cooling technology field, is specifically related to a kind of with the dry type being automatically adjusted bellows
Slag extractor and the outside bellows for dry-type slag extractor.
Background technology
Dry Slag Removal System has multiple advantage, such as the small incidental expenses water yield, without water resources consumption, non-wastewater discharge, beneficially environment
Protection.Dry-type slag extractor has air inlet, can be manually operated or rely on boiler furnace negative pressure to open air inlet, by air intake
A small amount of natural wind that mouth enters directly contacts with bottom ash, on the one hand promotes that in bottom ash, imperfect combustion carbon burns away, another
Aspect, the surrounding air absorbing bottom ash heat returns feeding burner hearth from boiler slag removal mouth, thus decreases imperfect combustion heat waste
Physical thermal of becoming estranged loses, and beneficially boiler efficiency improves；Lime-ash burning after cooling is abundant, uncompleted burned carbon content is low, without
Hydrolyze and maintain activity, improve comprehensive utilization value.Dry Slag Removal System makes boiler slag removal system simpler, arranges
Convenient, floor space is little, saves station-service ground.During boiler coke, hydraulic breaker intercept, to be combusted fully after the most broken
Broken, effectively protect lower part equipment, do not have the explosion phenomenon of wet dreg removing system.Additionally, dry slag is without the melancholy of icing, in north
Cold district storage slag storehouse, side is without considering antifreezing measures.Current domestic large-scale electric station uses Dry Slag Removal System.
But there are problems in current slag drying machine, such as due to air inlet is not easy to the air controlling to cause entering lag cooler
Can not control air quantity, unit air inlet under any load is at 100% aperture, it is impossible to realize automatically controlling.If total wind
Measure little, the temperature exceeding standard of the slag notch of slag drying machine, follow-up slag-conveying device is had an impact；If total blast volume is big, dry-type slag extractor
Although the temperature of slag notch meet the temperature requirement of regulation in code, but the total blast volume entering burner hearth becomes big, and pathogenic wind-warm is not
The License Value of boiler can be met, cause smokejack temperature to rise, cause the thermal loss of boiler to affect its efficiency.
CN201680391U discloses the slag drying machine of a kind of band air door automatic regulating device, outside its air door automatic regulating device includes
Housing, rotating mechanism, air door executer and bearing block, rotating mechanism is fixed on shell body by installing rack and bearing block；
Air door executer connecting steering mechanism, rotating mechanism connects damper blade.The aperture of air door control be by be arranged on slag notch,
Sensor passes signal at boiler bottom air inlet, each air door is to System Control Center, then by System Control Center feedback letter
Number to air door executer complete specify damper blade aperture.
In prior art, although have part slag drying machine cooling air quantity to realize intelligent automatic control, however it is necessary that deslagging fuselage
All air inlets install air door executer, and on the one hand this technical scheme considerably increases improvement cost, on the other hand due to each wind
Air flow condition near Men is different, is controlled each air door according to wind speed, adds the process of System Control Center
Difficulty and throttle opening error, actual self-regulation ability is the best.
