Description
Technical field
The present invention relates to technical field of cement production, specially manufacture of cement one section of grate fan outlet gear of grate-cooler
Wind apparatus.
Background technique
Grate-cooler is the critical host equipment in the sinter leaching system of cement plant, and major function is carried out to clinker
Cooling, conveying；Hot-air is provided for rotary kiln and dore furnace etc. simultaneously, is the capital equipment of firing system recuperation of heat.Grate-cooler
Blower provides cold wind for clinker cooling, cools down clinker by heat exchange, is indispensable important equipment in grate-cooler.
In grate-cooler actual production process, one section of grate plate is easiest to " Red River " phenomenon occur.Clinker is in the cooling procedure of grate-cooler:
The high temperature chamotte fallen from kiln hood is deposited in cooling machine inlet grate.It pushes forward and is covered in entire grate with grate plate,
Cold wind is combed seam upwards through clinker layer, and clinker is gradually cooled down during promotion.And the quality of clinker cooling depends on
The resistance of clinker layer is penetrated in cold wind.Resistance is small, and the cold blast rate of transmission is more, then the clinker temperature of grate-cooler is low out.Resistance is big, then
Grate-cooler clinker temperature is high out.
When cold wind penetrates the high temperature chamotte bed of material, heat exchange acts on strongly because the temperature difference is larger between fertilizer, at this time high temperature
More heat is transmitted to cold wind by clinker, and temperature increases after cold wind is heated, and volume increases therewith, penetrates the air velocity of the bed of material
Also it increase accordingly.Gas penetrates the resistance of the bed of material with square increase of air velocity, and the bulk density of gas increases with temperature and subtracted
It is small, the result is that air permeance resistance increases with gas flow temperature and is in a square increase.Otherwise when air-flow clinker layer lower through temperature,
The air-flow temperature difference is small, and the low then resistance of the gas temperature of transmission is also low, and air is easily penetrated from the clinker layer in lower resistance region, and gas penetrates
The more, clinker temperature is lower for amount.With the promotion of grate plate, the temperature difference between thick on same cross section, thin clinker particles layer is cured
Come more greatly, cold wind is more and more concentrated to be penetrated from the clinker layer of larger particles, and fine grained clinker layer cannot cool down, and form one
From cooling machine inlet to discharge port, red clinker band, the reason of appearance here it is " Red River " phenomenon, " Red River " phenomenon causes to comb
Plate damage frequency is high, and fan efficiency reduces, and while constraining rotary kiln yield and further play, also affects clinker
Quality.
Such as a kind of Chinese Patent Application No. CN201720165848.9 one section of grate fan outlet of grate-cooler keeps out the wind dress
It sets, belongs to manufacture of cement grate-cooler equipment technical field.The abat-vent includes the first wind deflector and the second wind deflector, described
First wind deflector is obliquely installed in grate-cooler air outlet bottom, and obtuse angle is formed on the first wind deflector and air outlet bottom；Described
Two wind deflectors are obliquely installed in the middle part of grate-cooler air outlet, and obtuse angle is formed on the extended line of the second wind deflector and air outlet bottom.
The device is set by the first wind deflector, the setting of the second wind deflector and the first wind deflector and the second wind deflector inclined direction
It sets, can effectively change the wind direction of cooling wind, avoid cooling dead angle, improve the cooling uniformity of material, avoid the occurrence of larger
High and low temperature it is poor, to effectively reduce the generation of " Red River " phenomenon.
This grate fan outlet abat-vent, although can be adjusted to a certain degree by the way that two wind deflectors are arranged in air outlet
It rectifies the incorrect style of work to reduce " Red River " phenomenon, but its oblique blowing mode inherently exists and to divide wind uneven in actual operation
Problem, it is easy to cause " Red River " phenomenon, while air damper structure of its fixed setting cannot cope in real work not Tongfang
" Red River " phenomenon that position generates, the function of not finely tuning, and the emergency case occurred in practical operation does not have coping style,
If grate plate damage causes high thermal material to be redirected back into the problem of air hose causes blower to damage, it is based on this, the present invention devises cement
Production one section of grate fan outlet abat-vent of grate-cooler, to solve the above problems.
