Description
Technical field
The invention belongs to granulating device field, particularly a kind of high temperature molten slag granulating device.
Background technology
In recent years, due to the utilizability of high temperature furnace slag, recyclable high temperature furnace slag waste heat not only, also can utilize the waste material of high temperature furnace slag.In the prior art, Iron And Steel Industry waste residue a kind of to recycle method be using further fine grinding and as the raw material of Cement industry after slag granulation.It is also the domestic main method of utilizing blast-furnace slag.It not only plays an important role to environment protection, can also produce very significant technical economic benefit.
Domestic main blast-furnace slag granulated processed method is grain slag facture at present, that is stokehold water quenching.Their main technological features is that in flowing to high-temperature slag when tap cinder, inject high pressure water makes slag chilling, thereby obtains grain slag.There is following problem in Water Quenching method: consumes a large amount of new water resourcess; The waste heat of slag cannot reclaim; Element in slag enters water vapour and produces S0
2and H
2s etc. bring atmospheric pollution.Therefore can adopt dry method cooling, when dry method is cooling, need granulation, be convenient to the abundant recovery of its cooling and waste heat in fluidized-bed.Conventionally the melt cinder pelletizer adopting has a kind of wind granulation; be that air blast operation machine is set under slag storehouse; the high-speed air flow that melt cinder blows out with gas blower when slag storehouse end flows out contacts; and rapid granulation, being blown to afterwards on water wall, melt cinder condenses into solid-state in operational process from liquid state; this wind granulation can be utilized the sensible heat of slag; but the cooling performance of high temperature melt cinder is bad, also have a lot of sensible heats fully not absorb, and traditional wind granulation degree is not high.
Summary of the invention
The technical problem solving:
Tradition water quenching can not make full use of the sensible heat of molten slag, and the broken degree of traditional wind is not high, and cooling performance is bad, and sensible heat absorbs insufficient.
Technical scheme:
For addressing the above problem; a kind of dry pulp water droplet gasifying device that puts out; comprise granulating device body, slag slag road, rotating cup, grain slag outlet, pneumatic outlet, main shaft and bearing; also comprise spraying nozzle; described spraying nozzle comprises spray orifice, converges chamber, stopcock and hickey, and spraying nozzle divides 4--8 to be fixed on granulating device body interior surrounding.
Described pneumatic outlet communicates with granulation storehouse above granulating device body.
Described spraying nozzle is beast horn shape.
In described spraying nozzle, have hybrid chamber, in the hybrid chamber of nozzle, stopcock is housed, the front end of nozzle has the spray orifice being communicated with hybrid chamber.
Beneficial effect of the present invention:
1, the present invention adopts water smoke granulation, makes the granulation degree of high temperature melt cinder more obvious;
2, after high-temperature flue gas purification, can carry out UTILIZATION OF VESIDUAL HEAT IN, save energy has reduced topsoil simultaneously.

Fig. 2 is the structural representation of spraying nozzle 3;
In figure:
1, grain slag outlet 2, granulation storehouse 3, spraying nozzle 4, granulating device body 5, pneumatic outlet 6, slag slag road 7, rotating cup 8, main shaft and bearing 9, spray orifice 10, converge chamber 11, stopcock 12, hickey.
Embodiment
For technique means, character of innovation that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
The invention provides the existing duster system of a kind of solution complicated, floor space is large, the expensive a kind of dry pulp water droplet gasifying device that puts out with high investment.
A kind of dry pulp water droplet gasifying device that puts out as shown in Figure 1, comprise granulating device body 4, slag slag road 6, rotating cup 7, grain slag outlet 1, pneumatic outlet 5, main shaft and bearing 8, it is characterized in that: also comprise spraying nozzle 3, described spraying nozzle 3 comprises spray orifice 9, converges chamber 10, stopcock 11 and hickey 12, and 4--8, spraying nozzle 3 minutes is fixed on the inner surrounding of granulating device body 4; Pneumatic outlet 5 communicates with granulation storehouse 2 above granulating device body 4; Spraying nozzle 3 is beast horn shape; In spraying nozzle 3, have the chamber of converging 10, stopcock 11 is equipped with in converging of spraying nozzle 3 in chamber 10, and the front end of spraying nozzle 3 has and the spray orifice 9 that converges chamber 10 and be communicated with.
Based on above-mentioned principle, a kind of dry pulp water droplet gasifying device that puts out as described in Figure 1, in use, blast furnace melt cinder is broken up into small grain size melt cinder while flowing to the rotating cup 7 of high speed rotating by slag slag road 6; Meanwhile, from water blast gun, flow into the high pressure water of spraying nozzle 3 through stopcock 11, converge converging chamber 10, and pass through in spray orifice 9 spirt granulation storehouses and form water smoke, in granulation storehouse 2, water smoke and dispersed small grain size melt cinder form convection current, and carry out heat exchange, water smoke is vaporization rapidly at high temperature, the little melt cinder sensible heat of high temperature is absorbed, and temperature declines rapidly, and the high-temperature smoke of generation rises, by pneumatic outlet 5, discharge purify, dedusting, and it is carried out to waste heat recovery; The little slag particle of solid in the 2 interior formation of granulation storehouse is discharged from grain slag outlet 1.
