Description
Как известно, основным затруднением дл осуществлени непрерывного процесса получени плава сульфидов при восстановлении сульфатов в механических печах вл етс образование прилипающих в процессе плавки к футеровке печей колец плава.As is known, the main difficulty in carrying out the continuous process of obtaining sulphide melt during the reduction of sulphates in mechanical furnaces is the formation of melt rings sticking to the lining of the melts in the smelting process.
Способ, составл ющий предмет насто щего авторского свидетельства, имеет целью устранить указанные затруднени .The method constituting the subject of this copyright certificate is intended to eliminate these difficulties.
Сущность его заключаетс в том, что весь процесс восстановлени сульфата осуществл ют в жидкой среде расплавленного сульфида: щихту из размолотого и тщательно перемешанного сульфата и угл непрерывно подают в поток расплавленного сульфида.The essence of it is that the entire process of sulfate reduction is carried out in a liquid medium of molten sulfide: solvents from ground and thoroughly mixed sulfate and coal are continuously fed into the stream of molten sulfide.
Перемешивание щихты с расплавленным сульфидом производитс путем вдувани в последний, например, генераторного газа. С помощью же вдувани последнего осуществл етс движение расплавленного сульфида в реакционной печи.The mixing of the molten sulphide is made by blowing it into the last, for example, generator gas. By means of injection of the latter, the molten sulphide is moved in the reaction furnace.
Расплавленный готовый сульфид непрерывно выливаетс из печи на шуппен-аппараты и превращаетс с помощью последних в чещуйчатые пласдинки.The molten finished sulphide is continuously poured out of the furnace onto the Schuppen apparatuses and transformed into the chests with the help of the latter.
Полученные на валах шуппен-аппаратов пленки плава непрерывно срезаютс ножами и сваливаютс в корыто дл выщелачивани плава гор чей водой, содержащее скребковый транспортер.Films obtained on the shuppen apparatus shafts are continuously cut by knives and dumped into a trough for leaching the melt with hot water containing a scraper conveyor.
Уход щий раствор сульфида отстаивают , фильтруют и осветленный собирают в сборник, из которого перекачивают на упаривание. При массовом производстве и недостаточной концентрации дл упаривани щелоков могут быть применены вакуум-аппараты, а окончательное упаривание может быть произведено в лодках или горшках. Отмытый же шлак поступает в отвал.The sulphide leaving solution is settled, filtered and clarified is collected in a collection, from which it is pumped to evaporation. In case of mass production and insufficient concentration, vacuum apparatus can be used to evaporate the liquor, and final evaporation can be carried out in boats or pots. The washed slag enters the dump.
Нагрета вода из вод ных рубашек газовых труб и шуппен-аппаратов поступает в сборник и служит дл выщелачивани плава сульфидов.The heated water from the water jackets of the gas pipes and shuppen apparatus enters the collection and serves to leach the sulphide melt.
Температура плава в печи 800-900° в зависимости от режима и сульфида.The temperature of the melt in the furnace is 800-900 °, depending on the regime and sulfide.
В случае переработки сульфида на карбонат надобность в уваривании щелоков отпадает и осветленный раствор без предварительного охлаждени поступает на карбонизацию по одному из известных способов, причем одновременно с карбонатом может быть получена сера или сероводород.In the case of sulphide processing on carbonate, the need for boiling liquor is no longer needed and the clarified solution without carbon cooling is fed to carbonization using one of the known methods, and sulfur or hydrogen sulfide can be obtained simultaneously with carbonate.
