A kind of method of heat exchange between the enhancing air and sinter bed that this specific embodiment provides, comprising:
Step S1 controls the air above sintering feed and flows along the direction of motion of sintering feed.
In above-mentioned steps S1, heat exchange has the characteristics that obvious and rule in sinter bed, red-hot more than burning zone
Sinter by heat be transmitted to by air, make air preheat, sinter cools off；In burning zone, hot-air be heated to
The solid fuel of ignition point acts on, and combustion reaction occurs, and releases a large amount of heat, this layer of temperature is made to reach 1300-1500 DEG C；Burning
When being moved downwardly to preliminary heating zone and drying layer heat exchange occurs between sintering feed for the high-temp waste gas of generation, to make to burn at this
Ramming material temperature quickly rises to the ignition temperature close to fuel and evaporates the moisture in sintering feed sharply and dry.
Step S2 sprays steam in the upper surface of sintering feed.
Compared with the prior art, due to 1.8 times that the specific heat of steam is dry air specific heat, so can be by sintering feed
Layer surface sprays steam to improve the specific heat of air, will form more in this way, the air of equivalent amount enters the bed of material just plus steam
Strong heat-exchange capacity, the exhaust gas that sintering process generates contain Boydii reaction and the imperfect combustion CO generated jointly of coke cutting, by
In the reinforcing of sintering process, fuel combustion chemical process is more complete, and gas phase vapor composition promotes CO and CO2Reaction, add
Fast the atmosphere variation of sintering process, reaction rate avoid sinter liquid from being cooled air impact and cause crystallographic texture different
Often, the phenomenon that destroying sinter strength；In addition, the water in steam encounters the carbon-coating of high-temp combustion, H can be cracked into2And O2, H2
Good gaseous fuel, O2It is strong combustion adjuvant for another kind, the completion of follow-up sintering process can be accelerated；And due to steam cracking
For H2And O2, additional fuel and O can be generated2Sintering process is added, can suitably reduce the fuel consumption of sintering, saves former
Material.
On the basis of the above embodiments, in order to make the steam being added preferably play a role, the injection of steam can be made
Position is located at the upper surface of the sintering feed within the scope of temperature inflection point, and temperature inflection point range is the model that sintering feed temperature steeply rises
It encloses, can be the range that sintering feed rate of rise in temperature is greater than or equal to 150 DEG C/min, certainly, temperature inflection point range needs root
Determine that there may be differences for different sintering processes according to actual conditions.
It needs to be illustrated, if steam directly sprays after sintering feed goes out ignition furnace, due to just going out ignition furnace, burn
Junction temperature is lower, and the water in steam enters after sintering feed, the temperature of sintering feed can be made to reduce, or even cause sintering process cannot
It is normally carried out；When carrying out steam injection at the middle part of sintering machine, since the water in steam resolves into H2And O2It is raw later that baked is fired again
At water electrode easily cause the lower part mixture moisture in sintering feed excessive, formed excessive moistening layer, influence the gas permeability of the bed of material, influence to burn
Tie the quality of mine；If the position of injection steam is rearward, sintering process all terminates, cannot play dependent interaction；Therefore it selects
It selects and sprays steam in temperature inflection point, specific heat capacity increases after admitting air into sintering feed, and increase the temperature of sintering feed, and this
When sintering feed temperature increase speed comparatively fast, not will form excessive moistening layer.
Certainly, since sintering machine crude fuel structure difference, the difference of size, the difference of Process configuration etc. will cause
The variation of temperature inflection point range, therefore, in actual production process, the range of temperature inflection point needs determines according to actual conditions, In
This is not repeated them here.
Preferably, temperature inflection point range is 220 DEG C to 390 DEG C.
