Existing a kind of forced-air blast formula annular cooler, circular cooler trolley is driven by the drive unit that motor, reductor, friction roller and friction plate etc. form.Its body is comprised of cooling chassis and walking rails, slewing frame, dust gathering arrester and bellows etc.Also have to give in addition, discharge trough, cooler stand, blast pipe, the ore deposit that falls reclaim equipment and the members such as powder conveyer, plate belt feeder, cooling blower, consisted of whole annular cooler.By the heat sinter after the thermal crusher fragmentation, by sending in the circular cooler trolley for the ore deposit chute.The chassis that is designed to the three-point support structure moves at circuit orbit, the cooling blast that is bloated by cooling blower, enter the sintering ore bed through bellows and chassis stage ventilation grate plate, make heat sinter be cooled to be lower than 150 ℃, cooled sintering deposit is discharged into apron conveyor from discharge trough and transports, and then is transported to whole grain workshop by belt conveyor.
In the air blast cooling procedure, from chassis ventilation grate plate institute powder downstairs, by wind box branch pipe acceptance, be discharged on the drag conveyor through the pneumatic type Double-deck cinder discharge valve, transported by rubber conveyer at last.In addition, be provided with the high-temp waste gas waste-heat recovery device for ore deposit section.Original central cooler adopts preferably seal closure of closure in high temperature section, install at the seal closure semi-open-type that middle low-temperature zone adopts, existing cooling system as shown in Figure 1, on the air inlet of ring cold-blast machine 2 muffler 1 is housed, the air outlet of ring cold-blast machine 2 is connected with ring packaged air conditioner 3 by pipeline, ring packaged air conditioner 3 is arranged on the bottom of circular cooler trolley 4, and seal closure 5 covers on the top of circular cooler trolley 4.In order to guarantee in maximum efficiency heat of cooling sintering deposit of cold wind that blower fan bloats; the ring air-cooler can be purged to a large amount of sintering deposit particles or the breeze that does not burn till in the atmosphere in the running; cause environmental pollution; even no matter be to adopt the chev(e)ron seal cover or adopt whole circle door type cover structure; all can only reduce the bulky grain ore and fly into amount in the atmosphere, also can't avoid the discharging of fine particle dust.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of low emission sintered ore cooling system, by behind the heat exchanger recovery waste heat dusty gas being sent into dedusting in the deduster, in the recycling booster fan circulation winding cold-blast machine, realize the zero-emission to surrounding environment.
The utility model is achieved in that a kind of low emission sintered ore cooling system, comprise ring cold-blast machine, the ring packaged air conditioner, circular cooler trolley and seal closure, described ring cold-blast machine air outlet is connected with the ring packaged air conditioner by pipeline, described ring packaged air conditioner is arranged on the bottom of circular cooler trolley, described seal closure is arranged on the circular cooler trolley top and seals cover circular cooler trolley fully, this cooling system also comprises heat exchanger, deduster and booster fan, described seal closure top is provided with air outlet, the air outlet of seal closure links to each other with the air inlet of heat exchanger by heat exchanging pipe, the air outlet of described heat exchanger links to each other with the air inlet of deduster by circulation line, and the air outlet of deduster is communicated with the air inlet of ring cold-blast machine after by the booster fan supercharging by pipeline.
Be parallel with the bleeder road on the described circulation line, described bleeder is provided with stop valve on the road.
Described deduster is bag dust collector.
Described seal closure is door type seal closure
The utility model low emission sintered ore cooling system is sent dusty gas into dedusting in the deduster after by the heat exchanger recovery waste heat, in the recycling booster fan circulation winding cold-blast machine, reach the balance of air quantity, and can play the zero-emission purpose to surrounding environment, need not the construction land that increases newly in the time of energy-conserving and environment-protective, improvement cost is very low, has widely application value.
