Description
Technical field
The invention belongs to technical field of metallurgical equipment, the dry gas current-sharing being specifically related in a kind of coke drying system and discharge equipment and method thereof.
Background technology
Coke is that modern blast furnace smelts one of essential crude fuel, it is possible to be the pig iron by the Fe3+ reduction of oxidation state. Modern blast furnace is all with coke as fuel, its in blast-furnace smelting mainly as heat-generating agent, reductive agent, stock column skeleton. Coke burns before air port and releases a large amount of heat and produce coal gas, heat is passed to furnace charge by coal gas in uphill process, the various physical-chemical reactions in blast furnace is carried out, in addition, coke or the carburizing agent of the pig iron, coke burning is also for furnace charge decline provides freeboard.
Coke moisture content is more big, sticks to the powder on coke and is more not easy screening and goes out, and after entering stove, reduces the ventilation property of blast furnace stock column, causes conditions of blast furnace fluctuation relatively big, causes coke consumption to increase, the increase of ton iron energy consumption. In theory, feeding density charcoal moisture content often increases by 1%, causes the usage quantity of coke about to increase (1.1～1.3) %. The reason causing feeding density charcoal moisture content higher at present has: 1) moisture content is infiltrated in wet quenching; 2) coke pore texture impact makes Absorption of Coke water-based strengthen; 3) outdoor storage; 4) outsourcing coke moisture content is uncontrollable. Therefore the moisture content reducing feeding density charcoal more and more receives attention and the concern of each iron and steel enterprise.
Current domestic coke oven dry thermal source generally has two kinds: one to be use process furnace to dry to coke, has drying time short, the advantage that the burnt moisture that dries is effective, but needs separately to build process furnace, and floor space is big, and investment is big, and coke dries cost height. Two is utilize hot-blast stove flue to give up flue gas drying coke, has less investment, and it is low that the little coke of floor space dries cost.
Present domestic iron and steel enterprises utilizes the technique of the useless flue gas drying coke of hotblast stove to be substantially all draw pre-hot gas house steward in hot-blast stove fume house steward's upper shed, under flue gas is caused blast furnace ore coke groove, at preheating house steward's end, an induced draft fan is installed, flue gas house steward after induced draft fan separates some pre-hot leg pipes, lead to each Jiao Cang respectively, to coke preheating in storehouse.Vapor pipe is installed on each top, coke storehouse the flue gas after coke preheating is discharged coke storehouse, if the patent No. is the Chinese patent of ZL201320859089.8.
But the technique utilizing exhaust gas of hot-blast stove oven dry coke is in actual use, still need perfect aspect, and (1) coke air-flow distributes uneven in coke storehouse, causes drying effect unstable; (2) exhaust effect is not good, and a large amount of useless flue gas overflows from feed bin top discharge opening, owing to also having a large amount of CO gas in waste gas, when groove lower area workman patrols and examines, it is easy to suck CO and security incident occur; (3) waste gas after drying coke contains a large amount of water vapour, and burnt groove discharging dust-removal system easily damages dust-removal system and dedusting fan after sucking the waste gas containing water vapour.
Summary of the invention
The deficiencies in the prior art in view of the above, it is an object of the invention to provide a kind of dry gas current-sharing and discharge equipment, drying air stream is uniformly distributed in coke storehouse, improve coke drying efficiency, reduce the ratio that the waste gas after drying overflows coke storehouse simultaneously, while improving discharge efficiency, avoid the waste gas after drying to enter dust-removal system, ensure the safe and stable operation of dust-removal system.
