Description
Technical field
The present invention relates to sintering deposit heat recovery technology field, more particularly to one kind is using chamber type sintering ore deposit waste heat recovery dress
The sintering deposit exhaust heat recovering method put.
Background technology
Steel and iron industry is the important foundation industry about national economy, and its energy-output ratio accounts for national industrial total energy consumption
15%, in steel manufacture process, the energy consumption of sintering circuit occupies second, generally the 10%~12% of iron and steel enterprise's total energy consumption,
Energy-saving potential is huge.At present, sintering machine generally uses air as medium and cooled down through straight line cooler or circular cooler,
Sintering deposit transfers heat to flue gas in cooling procedure, and flue-gas temperature is between 100~400 DEG C.Wherein, belt-cooling machine and ring are cold
Machine I, (270 DEG C~450 DEG C) of the high-temperature flue gas of II section of generation can be used for waste heat boiler to produce low-pressure steam, and III section later low
Warm flue gas is directly diffused mostly because reclaiming difficulty.
The existing waste heat reclaiming process of sintering deposit mainly has the disadvantage that：
1) energy recovery efficiency is low.With continuous cooling of the sintering deposit on cooler, the temperature of resulting flue gas is continuous
Reduction, corresponding smoke heat energy quality (Value) also constantly reduction, only I, II section take the flue gas of wind to can be used for producing steam, it is other
Section flue gas is because of Effective power contained by heat energyIt is less, it is unfavorable for reclaiming, directly discharge can only be selected.
2) system air-tightness is poor.Most of straight line cooler and circular cooler are architectural limitation, system air-tightness phase
To poor, partial fume loss is caused, because flue-gas temperature is higher and entrainment sintering deposit dust, easily environment is polluted, and
Safety in production is caused a hidden trouble.
The content of the invention
The invention provides a kind of sintering deposit exhaust heat recovering method of use chamber type sintering ore deposit waste-heat recovery device, with behaviour
Make the features such as continuous-stable, air-tightness are good, heat exchange efficiency is high, waste heat recovery quality is high；It is used for invention also provides one kind
Realize the sintering deposit residual neat recovering system of this method.
In order to achieve the above object, the present invention is realized using following technical scheme：
Using the sintering deposit exhaust heat recovering method of chamber type sintering ore deposit waste-heat recovery device, comprise the following steps：
1) the red heat sintering deposit after sintered is transported and poured into sintering deposit surge bunker, then slow and constantly slip into
In chamber type sintering ore deposit waste-heat recovery device；
2) plate is dropped down in both sides along height to Multi-layer exchanging heat flowing is staggeredly equipped with chamber type sintering ore deposit waste-heat recovery device, and every layer is changed
The inside inclined downward of plate is dropped down in heat flow；It is uniformly distributed first into the red heat sintering deposit in chamber type sintering ore deposit waste-heat recovery device
In the superiors, heat exchange flowing is dropped down on plate, is then slided downwards under gravity and is fallen on next layer of heat exchange flowing and drops down on plate；
So successively glide, finally accumulate to form the sintering deposit bed of material in chamber type sintering ore deposit waste-heat recovery device bottom；From chamber type sintering ore deposit
Waste-heat recovery device bottom enter recyclegas through feeder it is uniform after flow up, initially pass through bottom accumulation sintering deposit
