Background technique
China's steel industry is greatly developed, and iron and steel output occupies first place in the world, and the raising for smelting iron efficiency also makes problems
It reveals, environmental pollution is serious, and atmospheric haze is severe, greatly reduces the residential environment in China.China's ironmaking life
It produces raw material and mainly uses iron ore sintering mine, belt is transported again after sinter production is mainly sintered by sintering machine, ring cold machine is cooling
It is input into blast furnace and smelts.Since the annular type of cooling has, at low cost, occupied area is small, overall utilization rate is high, environment protecting
It is widely adopted well, but ring cold machine mainly passes through batch meter in the cooling procedure of sinter at present, through being fed chute
For cloth on annular cooler, then by the cooling sinter of air blast, the high temperature exhaust gas that High-temperature cooling section generates send cogeneration,
Sub-cooled section exhaust gas outlet.But this type of cooling there are sintering flue gas temperature it is low, utilization rate of waste heat is poor the problems such as, cause big
Amount low temperature waste gas (140-160 DEG C) can not handle utilization, seriously constrain heat sinter high temperature energy recovery efficiency, do not meet and work as
The policy of preceding national energy conservation and emission reduction.
Summary of the invention
Technical problem solved by the invention is to provide a kind of sintering ore cooling device, to solve knot process heat loss,
Improve sinter cooling procedure energy utilization efficiency.
The technical solution for realizing the aim of the invention is as follows：
A kind of sintering ore cooling device, including receiving cone, sealing plate, cylinder, discharge nozzle, ring cold machine；
The lower end of the receiving cone is connected with cylinder upper end, and sealing plate is equipped between the cylinder and receiving cone；Institute
It states cylinder lower end and is connected through discharge nozzle with ring cold machine；The cylinder upper end is equipped with waste gas outlet；The discharge nozzle is tilting knot
Structure, discharge nozzle is axial and ring cold machine lower end surface angle is acute angle；The exhaust gas that high temperature sinter is blasted in cylinder interior and ring cold machine
Contact cooling, improves exhaust gas temperature；The ring cold machine bottom is equipped with multiple blast orifices, and air blower is from blast orifice to burning in ring cold machine
Knot mine is finally cooled down.Ring cold machine does not generate exhaust gas, and all cooling exhaust gas pass through cylinder side wall air outlet and send outside to waste heat
Electricity generation system.
Compared with prior art, the present invention its remarkable advantage：
(1) sintering ore cooling device of the utility model passes through tilting discharge nozzle and ring cold machine fricting movement with cylinder
Instead of chute cloth, sinter percentage of damage is reduced.
(2) sintering ore cooling device of the utility model, cylinder is directly connected with ring cold machine by tilting discharge nozzle, whole
Body is preferable, reduces and leaks out.
(3) air blast waste heat exhaust gas can be fully entered cylinder, reduced low by the sintering ore cooling device of the utility model
Calorific value exhaust gas generates, and improves flue-gas temperature after cooling, improves residual heat generating efficiency.
(4) sintering ore cooling device of the utility model will move into annular cooling cylinder, make ring behind the high-temperature region on ring cold machine
The decline of cold temperature, reduces ring cold machine sideslip risk.
Present invention is further described in detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the general structure schematic diagram of sintering ore cooling device of the invention.
Specific embodiment
