Description
Изобретение относится к металлургии, 8 частности к грануляции металлургических шлаков.The invention relates to metallurgy, 8 in particular to granulation of metallurgical slag.
Целью изобретения является снижение энергозатрат.The aim of the invention is to reduce energy consumption.
На фиг. 1 представлен гранулятор, продольный разрез; на фиг. 2 - вид А на фиг. 1.In FIG. 1 shows a granulator, a longitudinal section; in FIG. 2 is a view A in FIG. 1.
Гранулятор расплава содержит желоб 1 для подвода расплава, носок 2 желоба.и коллектор 3 с соплами 4 для подачи воздуха. Коллектор выполнен с торцовой стенкой 5. Сопла 4 проходят через днище сноска 2. Носок смонтирован с зазором 6 относительно торца и боковых стенок.The melt granulator contains a chute 1 for supplying the melt, a toe 2 of the chute. And a collector 3 with nozzles 4 for supplying air. The collector is made with an end wall 5. Nozzles 4 pass through the bottom of the footnote 2. The toe is mounted with a gap 6 relative to the end and side walls.
Гранулятор встраивается в приемный бункер гранустановки, заполненный водой (не показано). Возможно применение этого гранулятора в установках шлакопереработки~'с утилизацией тепла расплава.The granulator is built into the receiving hopper of the granulator, filled with water (not shown). It is possible to use this granulator in slag processing plants ~ 'with utilization of melt heat.
Гранулятор работает следующим образом.The granulator works as follows.
Выпускаемый из плавильной печи расплав стекает по желобу 1 в носок 2 и затормаживается торцоеой стенкой 5 коллектора 3. Под действием воздуха, выходящего из коллектора 3 через сопла 4 и зазор 6, расплав диспергируется и увлекается воздухом в направлении его движения. Поток воздуха из зазора 6 предотвращает контент расплава.с торцовой стенкой 5 и с боковыми стенками и выброс расплава из носка в нераздробленном виде. При полете частицы расплава частично охлаждаются и падают в воду приемного бункера для ещ^ большего охлаждения, последующего извлечения из воды, обезвоживания и отгрузки потребителям. Благодаря контакту до частиц расплава с водой в частично охлажденном состоянии снижается образование характерных для процесса грануляции шлаков вредных соединений (сероводорода).The melt discharged from the smelting furnace flows down the chute 1 into the sock 2 and is inhibited by the end wall 5 of the collector 3. Under the action of air leaving the collector 3 through nozzles 4 and the gap 6, the melt is dispersed and entrained in the air in the direction of its movement. The air flow from the gap 6 prevents the content of the melt. With the end wall 5 and with the side walls and the discharge of the melt from the sock in an unbroken form. During the flight, the melt particles are partially cooled and fall into the water of the receiving hopper for further cooling, subsequent extraction from water, dehydration and shipment to consumers. Due to the contact of the particles of the melt with water in a partially cooled state, the formation of harmful compounds (hydrogen sulfide) characteristic of the slag granulation process is reduced.
В связи с наличием торцовой стенки и размещением сопел в его днище весь воздух участвует в дроблении и увеличении расплава.Due to the presence of the end wall and the placement of nozzles in its bottom, all air is involved in crushing and increasing the melt.
Экономический эффект достигается 2θ за счет экономии энергозатрат на диспергирование и транспортировку расплава и гранулята.The economic effect is achieved by 2θ due to the saving of energy costs for dispersing and transporting the melt and granulate.
