Claims (6)

1. Способ улавливания газопылевых выбросов при завалке шихты в конвертер, включающий загрузку лома, заливку жидкого чугуна из ковша, подвешенного на грузоподъемном кране в наклоненный конвертер и подачу нейтрального газа в рабочее пространство конвертера через его горловину, отличающийся тем, что нейтральный газ подают не менее чем двумя парами струй, которые располагают одна над другой и направляют в зазор между горловиной конвертера и верхним торцом заливочного ковша, при этом в верхней струе нейтрального газа дополнительно подают распыленную воду.1. A method for collecting dust and gas emissions when loading a charge into a converter, including loading scrap, pouring molten iron from a ladle suspended on a crane into a tilted converter, and supplying neutral gas to the converter working space through its neck, characterized in that the neutral gas is supplied at least than two pairs of jets, which are placed one above the other and directed into the gap between the neck of the converter and the upper end of the pouring bucket, while in the upper stream of neutral gas an additional dusting water. 2. Способ по п.1, отличающийся тем, что расход нейтрального газа в нижней струе в процессе заливки чугуна непрерывно уменьшают, а в верхней увеличивают.2. The method according to claim 1, characterized in that the flow of neutral gas in the lower stream during the pouring of cast iron is continuously reduced, and in the upper increase. 3. Способ по п.1, отличающийся тем, что нижние струи нейтрального газа располагают в вертикальной плоскости, проходящей через центр горловины наклоненного для заливки чугуна конвертера, а верхние струи нейтрального газа с водой - под углом к ней.3. The method according to claim 1, characterized in that the lower jets of neutral gas are arranged in a vertical plane passing through the center of the neck of the converter, which is tilted to cast iron, and the upper jets of neutral gas with water are at an angle to it. 4. Устройство для улавливания газопылевых выбросов при завалке шихты в конвертер, содержащее укрытие конвертера с проемом для загрузки материалов, расположенные на укрытии сопла для подачи газа и газоотводящий тракт с газоочисткой, отличающееся тем, что сопла установлены симметрично относительно горловины наклоненного для заливки чугуна конвертера, не менее чем двумя парами, причем дополнительно в одну пару сопел, аксиально с ними, установлены сопла для подачи воды.4. A device for collecting dust and gas emissions when loading the charge into the converter, comprising a converter shelter with an opening for loading materials, located on the shelter of the gas supply nozzle and a gas exhaust path with gas cleaning, characterized in that the nozzles are installed symmetrically with respect to the neck of the converter cast iron, no less than two pairs, moreover, in one pair of nozzles, axially with them, nozzles for supplying water are installed. 5. Устройство по п.4, отличающееся тем, что оси сопел для подачи газа расположены в вертикальной плоскости, проходящей через центр горловины наклоненного для заливки чугуна конвертера, а оси сопел для подачи газа с водой ориентированы под углом к ней.5. The device according to claim 4, characterized in that the axis of the nozzles for supplying gas are located in a vertical plane passing through the center of the neck of the converter, inclined for cast iron casting, and the axis of the nozzles for supplying gas with water are oriented at an angle to it. 6. Устройство по п.4, отличающееся тем, что перед соплом для подачи воды установлен завихритель потока.6. The device according to claim 4, characterized in that a flow swirl is installed in front of the water supply nozzle.
