Description
Technical field
The invention belongs to and melt the slag processing, relate in particular to iron-smelting blast furnace slag treatment unit.
Background technology
Blast furnace slag is the significant by-products that ironmaking is produced, and is rich in SiO in the slag
2, Al
2O
3, CaO, MgO etc., be the high quality raw material of producing cement through the grain slag of shrend granulation.Slag treatment directly influences blast furnace ironmaking production, and slag treatment is good, punching out rate height, and smooth operation of furnace, stable yields, economic benefit and environmental benefit are good; If slag treatment is bad, cause the wasting of resources, contaminate environment causes the blast furnace checking even is forced to damping down stopping production.In the prior art INBA method comprise in Punched box, water slag groove, grain slag groove, communicating pipe, divider, drum filter, the tube conveyor with treatment unit and transport conveyor, the funnel that catchments, hot tub, cooling pump, cooling tower and affiliated facility, slag flushing pump, be connected successively.During flushing cinder, blast furnace slag flows into Punched box by the slag ditch, High-Pressure Water shrend punching out through the Punched box ejection becomes grain slag, along with current enter water slag groove, grain slag groove, communicating pipe, divider, fall into drum filter and dewater, the grain slag after the dehydration is fallen on the interior conveyor and is transported through the transhipment conveyor.Flushing cinder water under filtering flows into hot tub through the funnel that catchments, and sends into cooling tower by cooling pump and carries out air-cooled cooling, and the cooling back is delivered to Punched box through the slag flushing pump pressurization again and used for flushing cinder to below 60 ℃, replenishes flushing cinder water and accident water with industrial water purification.This device dehydrating effect is good, mechanize, level of automation height, and the stokehold operating environment is good.But have obvious defects: the equipment of configuration and facility complexity, unreasonable, take up an area of many, investment is big, working cost is high; The particulate grain slag is many in the flushing cinder water, and equipment attrition is serious, accumulated slag in cooling tower, hot tub, the funnel that catchments, and blocking pipe, the equipment failure rate height, blowing rate of slag is low, and the maintenance amount is big, and scarfing cinder labour intensity is big, influences blast furnace production; Flushing cinder make up water consumption is big, needs to replenish waste water resource with industrial water purification.
Summary of the invention
In order to overcome the defective that prior art exists, the object of the present invention is to provide reasonable, the simplification of a kind of equipment and facilities Allocation, investment reduces, and working cost is low, and equipment failure rate is low; The blowing rate of slag height, granulation is effective, the blast furnace cinder water quenching processing unit that the flushing cinder water cycle is used.
Blast furnace cinder water quenching processing unit comprises conveyor in pelletizer, water slag groove, grain slag groove, communicating pipe, divider dashpot, drum filter, the tube, transhipment conveyor, settling tank, water reservoir, slag removing mechanism, slag flushing pump, valve and connecting tube.Water slag groove connects pelletizer and grain slag groove, and grain slag groove top is provided with the steam discharge cover, and the bottom connects pipe, and the divider dashpot that is connected with communicating pipe stretches in the drum filter, and conveyor is connected mutually with the transhipment conveyor in the tube, is connected to finished bin.Be characterized in cancelling cooling tower and auxiliary facility, settling tank, water reservoir are set under drum filter, two ponds are communicated with by the overflow weir that is located on the pool wall; Slag removing mechanism is set on the settling tank, and water reservoir directly is connected with pelletizer by pipe connection valve, slag flushing pump.During flushing cinder; red-hot blast furnace slag is by the slag ditch pelletizer of flowing through; the constant voltage high speed water jet impact slag of pelletizer ejection is with the slag water quenching granulation; grain slag flows to the further broken granulation of grain slag groove and leaches the bulk slag along water slag groove with current; water vapor is discharged by the steam discharge cover; grain slag flows into drum filter by communicating pipe and connected divider dashpot again and dewaters, and drum filter is by the rotary drum actuator drives.Grain slag is fallen on the interior conveyor, is transported to finished bin through the transhipment conveyor; The flushing cinder water filter that has the particulate grain slag is deposited in particulate grain slag at the bottom of the pond and is pulled out by slag removing mechanism and transport in settling tank, and the flushing cinder water of post precipitation flows into water reservoir by overflow weir, directly delivers to the pelletizer nozzle with the slag flushing pump pressurization again, so recycles.
The present invention compared with prior art, its advantage is:
1, this appliance arrangement and facilities Allocation simplification, reasonable, investment reduces significantly, working cost is low;
2, flushing cinder water is purified, and has alleviated equipment attrition, avoids line clogging, and service life of equipment prolongs, and the maintenance amount reduces, and saves lot of materials and labour cost, and scarfing cinder is convenient, reduces labor intensity;
3, breakdown rate is low, and blowing rate of slag reaches more than 99%, helps smooth operation of furnace, stable yields;
4, the closed cycle of flushing cinder water is used, and accomplishes sewage " zero " discharging, replenishes water purification less, has saved water resources, the protection environment.
2500 cubic metres of blast furnaces in our company successively adopt INBA method treatment unit and this device, and the equipment configuration reduces 30%, and a year power consumption is reduced to 3,550,000 KWh by 5,550,000 KWh; Prolong equipment life more than one times, save spare part, material and the labour cost of half maintenance; Water saving, ton slag consume the clear water amount and reduce to 0.4 cubic metre by 0.9 cubic metre, avoid the flushing cinder environmental pollution by water; Equipment failure rate significantly reduces, and blowing rate of slag improves more than 10%, guarantees smooth operation of furnace, stable yields effectively, and economic benefit is remarkable especially.
