СПОСОБ ОБРАБОТКИ ИЗМЕЛЬЧЕННОГО МАТЕРИАЛА В ПСЕВДООЖИЖЕННОМ СЛОЕ И СПОСОБ ПОЛУЧЕНИЯ РАСПЛАВА ЧУШКОВОГО ЧУГУНА ИЛИ ЖИДКИХ ПОЛУФАБРИКАТОВ СТАЛИ

Номер: RU2178001C2

В способе обработки измельченного материала в псевдоожиженном слое измельченный материал поддерживают в псевдоожиженном слое при помощи обрабатывающего газа, проходящего снизу вверх, и за счет этого обрабатывают. Обработке подвергается измельченный материал с широким распределением размеров зерна, имеющий относительно высокое содержание мелких частиц, а скорость обрабатывающего газа в свободном сечении в псевдоожиженном слое поддерживают меньшей, чем скорость, которая требуется для псевдоожижения самых крупных частиц упомянутого измельченного материала, при этом и крупные, и мелкие частицы перемещаются вверх и их выгружают через верхнюю область псевдоожиженного слоя. Скорость газа поддерживают в диапазоне 0,25-0,75 скорости, которая требуется для псевдоожижения самых крупных частиц. После предварительной обработки руду подают в плавильно-газификационный аппарат, где плавят с одновременным образованием восстановительного газа. Реализация изобретения позволит минимизировать потребление обрабатывающего газа и снизить унос мелких частиц обрабатывающим газом. 2 с. и 4 з. п. ф-лы, 3 ил.

Process and equipment for the smelting of fusible materials such as ore concentrate, utilising unspent reducing gas from the top-blowing process in the melting cyclone

Номер: DE0003638204A1
Принадлежит:

Due to the known incomplete conversion of reducing gases in top-blowing reactors, gas fractions containing CO and H2 pass into the waste gas system, where they must be afterburned in appropriate devices. The energy thus released can frequently not be usefully exploited, which adversely affects the overall energy balance of such processes. In the process according to the invention, the unspent reducing gas is passed along in countercurrent to the melt and serves as secondary fuel in the melting cyclone. As a result, not only is the energy balance improved, but at the same time the ingress of false air in the top-blowing reactor and the deterioration in quality due to back reaction of the molten metal with the waste gas of the roasting and smelting process are prevented.

METHOD AND APPARATUS FOR FORMING A DIRECTIONED SUSPENSION SPRAY OF A PULVEROUS MATERIAL AND A REACTION GAS

Номер: CA1170431A

ABSTRACT OF THE DISCLOSURE The invention relates to a method and apparatus for forming a directioned and controlled suspension spray of a pulverous material and reaction gas in such a manner that the reaction gas directed along one, often horizontally approaching channel is divided into three or more partial channels by means of mainly radial partition walls. When necessary, guide blades or a venturi-like mixing and guide member is used. The reaction gas is deflected so as to have the desired direction, often vertically downwards so as to be parallel to the central axis of the reaction chamber, such as a flash-smelting furnace. The thus formed partial flows of reaction gas are often caused, furthermore, to discharge, divided further into two or more parts, as an annular flow encircling on each side the member for feeding pulverous material, situated in the middle of the flow, into the reaction chamber. The pulverous material, dispersed well only in the reaction chamber, is mixed effectively with this as a whole non-rotating but turbulent reaction-gas flow, the pulverous material being directioned mainly radially in order to achieve a velocity difference between the reaction gas and the pulverous material.

Process for reduction smelting of materials containing base metals

Номер: US4857104A
Принадлежит: Vale Canada Ltd

A process for reduction smelting of copper-, nickel- or cobalt-containing materials in which such a material, at least partly in oxidic form is heated or combusted in finely divided form in a neutral or oxidizing flame to provide superheated particles. The superheated particles are then distributed onto a thin layer of coke. The materials in the particles are reduced in the thin layer of coke to metals or mattes or, in the case of iron, to wustite which forms a discardable slag with flux. Reduced product and slag form separate molten layers underneath the thin coke layer. All heat necessary for reduction and melting of product and slag is provided directly by the flame both in sensible heat in the superheated particles and by radiation.

Method and installation for the indirect reduction of particulate oxide-containing ores

Номер: WO2002000945A1

The invention relates to a method for the indirect reduction of particulate oxide-containing ores, especially iron oxide containing material, in a fluidized bed method at a pressure < 5 bar. According to the inventive method, the ore is heated up in a fluidized bed reactor (1) that is configured as a pre-heating stage (5) using a reducing gas produced from coal. Optionally, the ore is also pre-reduced, and is then reduced to sponge iron in at least one fluidized bed reactor (2, 3) that is configured as a reduction stage (7, 8). The reducing gas is guided via a reducing gas feed (12) or reducing gas pipe (13) in a counter-current to the material to be reduced which is guided from stage to stage from the reduction stage (7, 8) to the pre-heating stage (5). After purification the reducing gas is removed as export gas. Heat is supplied to the reduction stage (7, 8) and/or pre-heating stage (5) by combustion of a part of the reducing gas provided for the indirect reduction in the reduction stage (7, 8) and/or in the pre-heating stage (5) together with oxygen and/or air.

Method of preheating and reducing metal oxides

Номер: RU2111260C1

Сущность: изобретение касается предварительного нагрева и предварительного восстановления рудных окисных материалов с использованием газовых отходов высокой температуры. Способ включает введение рудных частиц и подачу в камеру горячего восстановительного газа с температурой выше температуры вязкости частиц окисла металла, вследствие чего частицы быстро нагреваются и принимают структуру потока, при которой их контакт между собой и внутренней поверхностью камеры обработки сводится к минимуму. Потоки захваченных частиц и восстановительного газа совпадают. Камера обработки удлинена в направлении движения потока и описана в спецификации. Горячие газовые отходы могут быть получены от реактора жидкой ванны и содержать высокие концентрации окиси углерода и водорода. Для избежания образования агломерации и настылеобразования частицы руды после нагрева до температуры, выше температуры их вязкости, резко охлаждают до температуры ниже температуры вязкости частиц. Структура потока частиц окислов металлов представляет собой структуру с минимальным контактом между ними. 9 з.п. ф-лы, 3 ил.

Принадлежит: Outokumpu Technology Oy

This invention relates to a method and a plant for the heat treatment of solids, in particular for reducing solids containing iron oxide, in a fluidized-bed reactor (5, 30). For fluidizing the solids, fluidizing gas is introduced into the fluidized-bed reactor (5, 30) via distributor grates (7, 32). Between a solids feed pipe (37) and a solids discharge pipe (38) of the fluidized-bed reactor (5, 30), the solids pass through multiple chambers (8, 34) each with a distributor grate (7, 32), which are at least partly separated from each other by weirs (6, 33). The pressure of the fluidizing gas introduced into the individual chambers through the distributor grates (7, 32), which are offset with respect to each other in vertical direction, substantially is the same. The delivery of the solids from the solids feed inlet 15 (37) to the solids discharge outlet (38) is promoted by the inclination of the fluidized-bed reactor (5, 30) with respect to the horizontal.
