Description
Technical field
The present invention relates to a kind of sinter is cooling and afterheat utilizing system, more particularly to a kind of closed sinter it is cooling and
Waste heat recovery apparatus.
Background technology
Steel and iron industry is high energy consumption industry, and 15% or so of whole nation industry total energy consumption is steel energy consumption, and steel produced
Effective utilization rate of energy in journey is relatively low, and only 30% or so.One of maximum energy consumption process is production sintering in iron and steel enterprise
The energy that mine is consumed, energy consumption can account for the 10% of entire energy consumption of iron and steel enterprises total amount.The cooling of sinter is steel life
Important process in production needs in cooling procedure to ensure that the quality of sinter is constant, while recovery waste heat as much as possible.At present,
Energy utilization rate is low in sinter production process, has 50% or so heat to be sintered machine flue gas and cooling equipment heat smoke band
It walks, wherein in the energy lost, the heat accounting taken away by cooling equipment heat smoke is up to 19%~35%.And China is being sintered
Utilization rate of waste heat is not high in production, larger with international most advanced level difference.
Currently, ring cold machine is the mainstream equipment that sinter cools down in steel industry, ring cold machine has at low cost, floor space
Small, the advantages that overall utilization rate is high, environment protecting is good.Sinter after high-temperature calcination is broken first, then falls into ring cold machine
Trolley in, uniform motion in orbit, cold air by air blower be sent into trolley under bellows, cold air is in the mistake across the bed of material
It exchanges heat with it in journey, takes away the partial heat of sinter, to cooling sinter.But ring cold machine only has front end high temperature sintering
Waste heat is utilized, and rear end low-temperature sintering waste heat fails to efficiently use, and ring cold machine sealing effect is poor, causes ring cold machine inside points high
Warm gas leak, cool exterior air enter ring cold machine, and waste heat air quality declines, and waste heat recovery rate is low, and country advocates " green
The requirement of production, energy-saving and emission-reduction " is increasingly stringenter.Therefore, there is an urgent need to research and develop a kind of waste heat recovery is efficient, power consumption values are low,
The novel closed-type sinter that environmental is low, operation cost is low cools down equipment.
Patent (200910187381) discloses a kind of perpendicular pot type retracting device of waste heat resources in sintering process and utilization side
Method, it is characterized in that：Sinter is fitted into enclosed tank body, is then passed through air from tank base, keeps sinter cold
But, while the sensible heat of sinter is almost all carried by air and is discharged by top of the tank and recycled.Sinter and air into
Row countercurrent flow, heat exchange efficiency is high, and heat recovery rate is high.The patent is established on the basis of the vertical cooling technique of sinter
On, using the form of countercurrent flow, improve heat exchange efficiency and waste heat quality.The vertical agglomerate cooling technique is to former cooling technique
Change larger, engineering construction difficulty is larger, and there are certain uncertainties.

Preferably, the transfer plate is made of the iron plate of same shape same material, and the thickness of transfer plate answers >=50mm,
Item seam is provided on transfer plate, slit width degree is 8-12mm, and transfer plate is divided into dynamic transfer plate and quiet transfer plate, and dynamic and static transfer plate is handed over
For arrangement.
Have retracting device below transfer plate, save bit by bit it is a certain amount of after recycling return mine and be sintered again.Preferably, retracting device
For grey bucket type, it is placed in duct bottom below cloth fan housing, detachably, recycling is returned mine after saving bit by bit a certain amount of fritter sinter burns again
Knot.
Preferably, partition board is equipped between cooling chamber, material is iron, is connected with closure interior welds.
Preferably, it is equipped with upper lower clapboard between adjacent cooling chamber, prevents gas from mutually circulating between cooling chamber, upper spacer is set to
On the bed of material of the top, there are a certain distance between the bed of material, ensure bed of material fluent motion；Lower clapboard be set to transfer plate it
Under, ensure that air inlet can smoothly enter into each cooling chamber.
Preferably, the tail end of the first, second and third cooling chamber be equipped with air-introduced machine, the 4th cooling chamber tail end be equipped with air blower, first
The tail end of cooling chamber is equipped with air blower.
The air blower of 4th cooling chamber is to provide air quantity and cold needed for cooling sinter, by second and third, four cooling
Room cools down, and gas temperature increases, and to meet the required cold of the first cooling chamber, air blower is installed below the first cooling chamber
It is the effect that cold is provided to wind is mended, air quantity is adjusted according to actual condition, it also can be normally closed.A kind of closed sinter is cooling and remaining
The working method of heat recovery equipment, high temperature sinter after crushing enter cooling equipment by feeding mouth, fall on transfer plate, warp
Sinter after cooling is sent to discharge port and is discharged by transfer plate, and cold air is first in the effect of the 4th cooling chamber lower end air blower
Under, by entering the 4th cooling chamber after the cloth fan housing of the 4th cooling chamber, cold air moves across transfer plate from bottom to top, and with biography
It send high temperature sinter on plate to exchange heat, the temperature of sinter is made to reduce, the temperature of air improves, and the air after heat exchange is cold through the 4th
But the gas gathering mask above room enters air circulating umbilical, and under the action of air-introduced machine, passes through the cloth fan housing below third cooling chamber
Into third cooling chamber, continue to exchange heat with high temperature sinter, herein temperature of the temperature of sinter than sinter in the first cooling chamber
Degree is high, and second of heat exchange is carried out between gas and sinter, Cryogenic air temperature can be made to further increase；Then, into
Cooling system is discharged after completing heat exchange here with sinter in two cooling chambers and the first cooling chamber, air, is filled into waste heat recovery
It sets.
