Abstract
The utility model discloses a gas-liquid mixed granulator for dry quenched slag. The granulator comprises a liquid slag bin (1), a liquid slag pipeline (2), a liquid slag valve (3), a hot air outlet (5), a slag discharge hole (6), a cooling wall (7) and a gas throttling valve (9). The granulator is characterized by also comprising a high-speed gas flow pipeline (10), a gas-liquid mixing pipeline (4) and a high-pressure nozzle (8), wherein the liquid slag pipeline (2) is connected with the gas-liquid mixing pipeline (4) through the liquid slag valve (3); the high-speed gas flow pipeline (10) is connected with the gas-liquid mixing pipeline (4) through the gas throttling valve (9); the tail end of the gas-liquid mixing pipeline (4) is connected with the high-pressure nozzle (8); and the high-pressure nozzle (8) is arranged in a cavity of the cooling wall (7). By adopting a gas-liquid mixing and high-speed jet mode, liquid slag is atomized, and the atomized liquid slag is granulated and cooled to exchange heat in the cooling wall (7), so the granulation degree is high, the pipelines are prevented from being blocked by high-speed gas flow, heat of the liquid slag can be recovered, and recycle of waste heat is realized.
Description
Technical field
The utility model belongs to the dried slag particle field of putting out, particularly a kind of dried gas-liquid mixed pelletizer that puts out slag.
Background technology
The utility model belongs to the dried slag particle field of putting out, particularly a kind of dried gas-liquid mixed pelletizer that puts out slag.
Summary of the invention
In recent years, because 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 with further fine grinding and as the raw material of Cement industry after the slag granulation.It also is 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 the grain slag facture at present, such as the stokehold water quenching.Their main technological features is, inject high pressure water makes the slag chilling in the high-temperature slag stream when tap cinder, thereby obtains grain slag.There is following problem in the Water Quenching method: consume a large amount of new water resourcess; The waste heat of slag can't reclaim; Element in the slag enters water vapour and produces S0
2And H
2S etc. bring atmospheric pollution; Therefore can adopt the dry method cooling, when dry method is cooled off, need granulation, be convenient to it and in cooling stave, cool off and the abundant recovery of waste heat.Usually the melt cinder pelletizer that adopts has a kind of wind granulation; be that air blast operation machine is set under the slag storehouse; melt cinder contacts with high-speed air flow that gas blower blows out during terminal the outflow from the slag storehouse; and rapid granulation; be blown to afterwards in the cooling stave, melt cinder condenses into rapidly solid-state in operational process from liquid state, although this wind granulation takes full advantage of the sensible heat of slag; production cost is very low, and price is also cheap.But because domestic blast furnace slag is basic slag, material property slag, domestic liquid slag and to be not suitable for wind broken.
Summary of the invention
The technical problem that solves:
The technical problem that the utility model is intended to solve provides and a kind ofly can improve liquid slag granulation degree, and can reclaim the device of liquid slag sensible heat.
Technical scheme:
For addressing the above problem, the utility model comprises the melt cinder storehouse, the melt cinder pipeline, the melt cinder valve, hot air outlet, slag-drip opening, cooling stave, gas throttling valve, described device also comprises the gas-liquid mixed pipeline, high pressure spray nozzle, high velocity air pipeline, wherein said melt cinder pipeline are crossed the melt cinder valve with the gas-liquid mixed device for cleaning pipeline and are connected, and the high velocity air pipeline is crossed gas throttling valve with the gas-liquid mixed device for cleaning pipeline and is connected, gas-liquid mixed pipeline tail end is connected to high pressure spray nozzle, and high pressure spray nozzle places in the cooling stave chamber.Gas-liquid mixed pipeline aft end portion pipeline shrinks, and high pressure spray nozzle places the cooling stave inner top.
Beneficial effect:
1, the utility model has been saved new water resources, has avoided the element in the slag to enter water vapour and has produced S0
2And H
2S etc. bring atmospheric pollution;
2, the utility model has fully reclaimed the sensible heat of liquid slag, has saved the energy;
3, the mode of high-velocity jet after the utility model has used liquid to mix, when making the melt cinder ejection, pressure drop, " blast " is vaporific particle, so granulation is more complete, the degree of granulation is higher.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model
1. melt cinder storehouse 2. melt cinder pipelines 3. melt cinder valves 4. gas-liquid mixed pipelines 5. hot air outlets 6. slag-drip openings 7. cooling staves 8. high pressure spray nozzles 9. gas throttling valves 10. high velocity air pipelines.
Embodiment
Be further described below in conjunction with 1 pair of the utility model of accompanying drawing.
A kind of dried gas-liquid mixed pelletizer that puts out slag; comprise melt cinder storehouse 1; melt cinder pipeline 2; melt cinder valve 3; gas-liquid mixed pipeline 4; hot air outlet 5, slag-drip opening 6, cooling stave 7; high pressure spray nozzle 8; gas throttling valve 9, high velocity air pipeline 10, wherein said melt cinder pipeline 2 is connected by melt cinder valve 3 with gas-liquid mixed pipeline 4; high velocity air pipeline 10 is connected by gas throttling valve 9 with gas-liquid mixed pipeline 4; gas-liquid mixed pipeline 4 tail ends are connected to high pressure spray nozzle 8, and high pressure spray nozzle 8 places cooling stave 7 chamber inner tops, and gas-liquid mixed pipeline 4 aft end portion pipe diameters are the trend of dwindling.
During device work, the high-temperature liquid state slag flows into melt cinder storehouse 1, through melt cinder pipeline 2, regulate by 3 pairs of melt cinder flow velocitys of melt cinder valve, make the melt cinder continuous uniform flow into gas-liquid mixed pipeline 4, high pressure gas are through high-speed gas-liquid pipeline 10 simultaneously, pass through again the flow of gas throttling valve 9 adjustments of gas, liquid slag and high-speed gas are fully mixed in gas-liquid mixed pipeline 4, again by high pressure spray nozzle 8 moments ejection, become rapidly and be vaporific small-particle, vaporific small-particle runs into the freezing air that is blown in the cooling stave 7 and cools off, cooled particle falls under gravity on the inclined-plane and flows out from slag-drip opening 6, and warm air enters waste-heat recovery device by the hot air outlet 5 that cooling stave 7 tops have.
The granulation degree that this device can improve liquid slag reclaims liquid slag sensible heat, has good economy and environment benefit.
