The accompanying drawing explanation:
Fig. 1 is (air-draft-type) continuous pallettype sintering machine schematic diagram:
(1) spreading system, (2) igniter, (3) chassis, (4) bellows, (5) head star wheel, (6) tail star gear, (7) single roller is broken, (8) vibratory sieve, (9) heat sensor, (10) electrical atomizing shower nozzle, (11) pipeline, (12) water vapour bag, (13) sealing, (14) protective cover, (15) blast control device, (16) peep hole
The specific embodiment:
Its principle adds the suitable quantity of water steam in the sintering deposit air of burning, and water gas reaction will occur on burning zone, generates hydrogen and carbon monoxide, and the reducing atmosphere of burning zone is strengthened, and more is conducive to the reduction of iron, thereby has reduced the iron oxide of sintering deposit.Simultaneously, because water gas reaction is the endothermic reaction, make again burned sintering deposit cooling fast, and the steam thermal conductivity factor is tens times of air, naturally is convenient to sintering deposit cooling.
Fig. 1 (air-draft-type) continuous pallettype sintering machine of take is example, start to install additional protective cover (14) and blast control device (15) from igniter (2) in the drawings, water vapour bag (12) connects electrical atomizing shower nozzle (10) by pipeline (11), electrical atomizing shower nozzle (10) is by heat sensor (9) gauge tap levelling size, 180 ℃-200 ℃ of 2-end, 100 ℃ of (cooking the bed of material 250 millimeter) afterbody ends of normal condition sintering machine middle part bellows heat sensors (9) temperature 1 bellows (4) heat sensors (9) temperature, at this moment the upper whole bed of material sintering deposit of chassis (3) is aglow, aglow.
The servicing unit of a kind of sintering machine of the present invention, start to install additional protective cover (14) from ignition of sintering process device (2) exactly, with the sintering machine main blower fan, is connected to afterbody, by blast control device (15), controls air quantity; Bed of material burning direction bottom, (large quantity of fluid is arranged in water vapour, and liquid water affects sinter strength to electrical atomizing shower nozzle (10) water spray steam.Must atomization) bellows heat sensor (9) temperature rises to 120 ℃ from 100 ℃, electrical atomizing shower nozzle (10) spray vapour more greatly, heat sensor (9) temperature starts to descend 119 ℃, this explanation steam is large, bed of material fire will go out, the vapour of this 120 ℃ of electrical atomizing shower nozzles of explanation (10) ejection just in time, but to a little bit smallerly a little again (prevent proportioning room or mixing machine, expect the irregular sintering quality that affects), first bellows of middle part have been calculated levelling well, whole sintering process is (constant speed) sintering at the uniform velocity by that analogy, namely the red bed of material of whole sintering guarantees in about 200mm to the afterbody end red bed of material of 2-end 1 bellows sintering deposit by 200mm---the last bellows heat sensor of 0mm afterbody temperature 50 C left and right.When tail star gear (6) chassis (3) discharging is broken to single roller broken (7), large calorimetric is distributed, 100 ℃ of left and right of heat sensor temperature, tail star gear (6) top, further steam fogization is cooling (can effectively prevent that dust from flying upward in spray, each producer's headache environmental protection of this point, easily just solved), until vibratory sieve 150 ℃ of left and right of finished product sintering deposit temperature out are just qualified.
Annotate: sintering process is the combined process of many physicochemical change, this process is not only intricate, and fast changing, within a few minutes in even several seconds, sintering feed just because of strong heat exchange from being heated to 1200～1400 ℃ below 70 ℃, meanwhile, it also will produce liquid phase from solid phase, and then liquid phase is again by rapidly cooling and solidify.Turn round and look at the scale difference of every sintering machine because of design, charge ratio difference and heat sensor installation site different temperatures can be variant; The difference and the scale that are mainly raw material differ, and the red thickness of feed layer of controlling sintering deposit is also different, and certainly, temperature controlling point also can be directly from the suitable red bed of material.It is just also the water-gas occurring principle that updraught sintering formula sintering machine vapor pipeline is sent the bellows air inlet to, comprises that ring type, belt, step-by-step movement, sintering machine box, the shaft furnace formula are also the water-gas occurring principles.Group's ball shaft furnace sintering is, at furnace bottom, water gas-generating device is set.
Water vapour bag (12) is to be installed at the peripheral hot water apparatus of igniter (2); because the temperature 300-1100 ℃ that igniter (2) is peripheral; and igniter shell often burns and changes; design has utilized the igniter waste heat like this; protect again igniter, claimed again the igniter type boiler.Water vapour bag (12) can directly replace by the water steam boiler; The waste heat that another ironworks utilizes is many especially, needs only the water vapour will produced, and with pipe, is connected on sintering machine to be sprayed directly on to burn on red clinkersintering ore deposit also can obtain the above results.
In practice, as protective cover (14), be connected to afterbody with centrifugal fan (also can with afterbody dedusting fan), control air quantity by blast control device (15), each scope of the enterprise differs, and demand differs, and sintering deposit temperature control meeting is variant, bellows are that a unit or several bellows are that the sintering deposit temperature control is realized in a unit, also can be connected with the sintering machine main blower fan.Peep hole (16) Functional observation is adjusted air quantity and distribution of steam situation.
