Description
Technical field
The invention belongs to nonmetallic materials production equipment technical field, more particularly to a kind of high-temperature calcination production cooling
Device.
Background technology
Nonmetallic materials are when being processed at present, it usually needs through high-temperature calcination, such as aluminium oxide, titanium dioxide etc., and
And be typically necessary after high-temperature calcination and carry out cooling treatment again.But some are required to be unable to the thermal sensitivity powder of secondary clacining
For shape product, it usually there will be cooling wind in cooling procedure and take back powder product and secondary clacining occurs in calcining kiln
Problem.
Taking a- aluminium oxide as a example, high-temperature calcination a- aluminium oxide as a kind of Novel environment-friendlymaterial material, its purposes more and more extensively,
It is worth an also road hurricane, by favorable comment and the selection of people from all walks of life.Its purposes is mainly ceramic industry, refractory material, abrasive material row
Industry, in addition also can process synthetic cut stone, and can be used for the fields such as aviation, guided missile, military affairs.But, no matter be used for which kind of industry, its
Final transformation of crystal is all must to carry out high-temperature calcination during a- aluminium oxide.
China's high-temperature calcination a- alumina-producing method mainly has at present: 1) down-draft kiln: this kiln type belongs to periodic kiln.Forge
During burning, raw material is loaded saggar, enter kiln and once calcine and just can be made into.But, due to being limited by kiln type structure, its temperature is general not
More than 1400 c °, and because kiln space is big, temperature control has larger difficulty, and its upper and lower, inside and outside temperature has larger mistake
Difference, is usually present the uneven defect of quality；2) tunnel cave: this kiln type belongs to seriality kiln.During calcining, raw material is loaded casket
Alms bowl, enters after fully calcined from kiln hood, then from kiln tail removal.The clinkering zone designing technique of this kiln is more ripe, section temperature
Little, temperature control effect is good, and calcining heat is up to 1600 c °, thus temperature is easily controllable.But, its exist high energy consumption, efficiency low,
It is difficult the shortcoming producing that maximizes；3) hollow rotary kiln: this kiln type belongs to seriality kiln.During calcining, raw material is entered by kiln tail,
From kiln hood removal after calcining, subsequently enter in cooler and cooled down, it is combustion-supporting that the secondary hot-air of cooler enters back into rotary kiln.Should
Kiln temperature degree is easily controllable, and burning zone temperature can be adjusted as needed, and the production that substantially can meet different calcining systems will
Ask, this kiln type production capacity is big, low production cost is it is adaptable to the larger product of production lot.
Wherein down-draft kiln and tunnel cave calcining after a- aluminium oxide from 1200 c ° about be cooled to 80 c ° adopt nature fall
Temperature, efficiency is low；Hollow rotary kiln calcining high temperature a- aluminium oxide adopts single cylinder cooling machine or spiral coolconveyer.Cold using monotubular
But during machine, because high-temperature calcination a- aluminium oxide is granular material (former grain size < 5um), for avoiding reentrainment of dust (thing in cooler
Material airborne dust enters rotary kiln burning impact product quality with secondary wind), do not set lifting blade in cooler, but generally adopt cylinder
External spraying cooling water is lowered the temperature, and now, the cooled water of 60% about heat energy is taken away, and causes energy consumption to increase；And spiral cooling is defeated
Machine is sent to adopt the outer u-shaped groove water cooling of body and spiral hollow axle water cooling, the cooled water of sensible heat of material is taken away, and increases energy consumption.
It is thus desirable to the exploitation new cooling device of energy-conservation, to realize energy-saving and emission-reduction.
Chinese invention patent cn103712462a, discloses between a kind of fly ash-lime stone calcined alumina self-efflorescence grog
