Description
Technical field
The bessemer furnace slag that the present invention relates to be produced in UTILIZATION OF VESIDUAL HEAT IN, solid waste processing and application technology as the second resource, the especially convertor steelmaking process in the ferrous metallurgy process is handled, and being specifically related to a kind of slag waste heat has treatment unit and the method explained by oneself of pressing.
Background technology
At present, the mode that slag is handled is a lot, and hot application method, hot vexed method, water quenching, wind quench method, cylinder shotting and granulation wheel method etc. are arranged.The hot application method is that the fused solution slag is poured in the hot application field, by fetching water or the air naturally cooling, carries out fragmentation, magnetic separation processing subsequently; The vexed method of heat is that the fused solution slag is poured in the hot vexed pond, by the cooling of fetching water, treats that the laggard row of slag efflorescence is broken, magnetic separation is handled; Water quenching is when toppling over the fused solution slag, with high pressure water with molten steel slag cooling and smash into particle; The wind method of quenching is similar to water quenching, and the wind method of quenching is with the molten steel slag cooling and smash into particle with high-pressure air.It is low that the hot application method is handled slag efficient, contaminate environment; The vexed method of heat, water quenching and the wind method of quenching adopts air or water to force cooling, and efficient is higher, and still hot vexed method, may be blasted because water directly contacts with molten steel slag with water quenching; Though the wind method of quenching is broken with the force air cooling, but compressed air consumption is big, noise is big.After drum process is meant and pours liquid steel slag into slag ladle, be transported between the processing of cylinder slag through slag car, through crane cylinder slag input device notch is arrived in the slag ladle handling then, and pour in the drum apparatus, liquid steel slag is discharged to the slag field through apron conveyor finish water spray cooling, curing, fragmentation simultaneously in cylinder after.This technology has problem to be solved: the slag processing rate is low generally below 50%, still has a large amount of dry residue emissions; System device power consumption height, breakdown rate is higher, and investment is big; Slag is difficult for the granulation that is crashed to pieces, and is serious to equipment attrition, and interior dress steel ball is often changed.Granulation wheel technology is after liquid steel slag is transported to treatment plant; adopt crane that slag ladle is slowly sling; pour in the granulation wheel of high speed rotating, make the slag crushing granulation, fall into the pond after the water spray cooling; slag is after granulation wheel shrend method is handled; granularity is little, and the slag compact crystallization is difficult levigate; its gelling property variation influences slag and uses at building material industry.
Summary of the invention
It is a cover pressurized vessel equipment that a kind of slag waste heat has pressure to explain device by oneself, and mainly comprise: waste heat is explained tank, jar door, slag chute, slag chute support, the track of mucking haulage, waterworks, control device, release gear, water-freeing arrangement and cooling system by oneself and formed; Wherein control device comprises pressure-detecting device, temperature-detecting device and security device.
Its waste heat has to press to be explained treatment process by oneself and is, the slag chute that certain temperature (300 ~ 800 ℃) slag will be housed pushes waste heat and explains by oneself in the tank and be positioned on the slag chute support; Close jar door and sealing locking; Explained by oneself the waterworks at tank top sprays water to slag by waste heat; Warm sludge is met water quick cooling, and the top layer lowers the temperature rapidly, and the stress that is produced by the temperature difference makes cracked and generation crack, slag top layer; And the slag waste heat add a large amount of low-pressure water steams that produce behind the hot water be covered in very soon slag the surface and infiltrate in the crack, react generation Ca (OH) 2 rapidly with the free state CaO in the slag, its weave construction changes, proportion diminishes, because increasing to produce, solid volume expands, have expansion stress, caused the rapid efflorescence of slag cracked.Because reaction process is to carry out in airtight pressurized vessel, the water vapour that the water spray back forms does not efflux, form certain pressure and temperature atmosphere in jar, under the effect of pressure, steam reacts by the inside that microscopic checks can be deep into block slag, rather than only rest on the surface of slag, and improved speed of response, make that clinker is further cracked rapidly, efflorescence.Said process carries out repeatedly, and from outward appearance to inner essence, the free state CaO in slag fully clears up and slag self efflorescence, makes the slag that has pressure to explain processing by oneself through waste heat reach stabilizing treatment and efflorescence processing two big purposes at short notice.Therefore waste heat has and presses that to explain treatment technology by oneself be to have solved bessemer furnace slag rapid stabilization and the advanced treatment technology of atomizing simultaneously.
It is a horizontal cylindric pressure vessel that described waste heat is explained tank by oneself, is provided with a jar door at the one end; Waste heat is explained tank by oneself and is used to form enclosed space with a jar door, makes slag explain efflorescence by oneself at this enclosed space.
Described slag chute is a clamshell structure, two lobes about being divided into, and two lobes can rotate around the rotating shaft at center, can automatic dischargings after opening from the bottom, slag chute is used to hold slag.
Described slag chute support is used to support slag chute.
The described track of mucking haulage is positioned at waste heat and explains a jar inwall bottom by oneself, and slag chute is explained tank by oneself by the track turnover waste heat of mucking haulage.
It is axial arranged that described waterworks is explained jar inwall top by oneself along waste heat, and waterworks is used for spraying water to warm sludge.
Described control device comprises pressure-detecting device, temperature-detecting device and security device, and control device is arranged in a plurality of positions that waste heat is explained tank and jar door by oneself, prevents that waste heat from explaining jar Yin Wendu or hypertonia by oneself and explode.
Described release gear is positioned at waste heat and explains tank outer wall top by oneself, and gas barrier is used to discharge waste heat and explains jar interior steam by oneself to keep a jar interior constant voltage.
Described water-freeing arrangement is positioned at waste heat and explains tank outer wall bottom by oneself, and water-freeing arrangement is used to get rid of the water that waste heat is explained tank inside by oneself.
Described cooling system comprises tank interior cooling and tank body exterior cooling two portions.The tank interior cooling can be cooled off slag chute, slag chute support and inner tank wall, and the tank body exterior cooling is cooled off a tank wall and a jar door.
The diameter of described jar door equates with tank diameter, opens afterwards waste heat and explains jar by oneself and can all open wide; The jar door is furnished with closing mechanism, locking mechanism and sealing mechanism, and closing mechanism is used for opening and closing jar door; Locking mechanism is used for locking jar door; Sealing mechanism is used for sealed can door and tank body.
The present invention utilizes the slag waste heat in the seal-off pressure container slag to be handled, and does not consume extra power, can not produce dust, energy-conserving and environment-protective; In the treating processes, water does not contact with molten steel slag, and pressurized vessel is furnished with security device, and is safe and reliable; Present method processing cycle lacks in addition, and efflorescence is effective, can fully clear up the free state CaO in the slag, and the slag good stability after the processing can be used for aspects such as building materials and road, can realize the resource utilization recycle of slag.
