Description

Известен способ получени  серы из колчедана с циркул цией сернистого ангидрида в псевдоожиженном слое.A known method for producing sulfur from pyrites with the circulation of sulfurous anhydride in a fluidized bed.

Описываемый способ получени  серы по сравнению с известным обеспечивает полное извлечение серы из колчедана, причем ислользуетс  не только циркул ци  сернистого ангидрида, но и циркул ци  колчеданного огарка. Особенность способа заключаетс  в том, что процесс ведут с циркул дией ксхлчеданного огарка в разделеннОМ в верхней части на две зоны аппарате с двойным иди несколькими псевдоожиженньши сло ми.In comparison with the known method, the described method of obtaining sulfur provides complete extraction of sulfur from pyrites, and not only the circulation of sulfur dioxide, but also the circulation of pyrite calcine is used. A feature of the method is that the process is carried out with circulating calcine calcine in the upper part of the apparatus divided into two zones with double or several fluidized beds.

На чертеже изображена схема установки с аппаратом, разделенным в верхней части на две зоны.The drawing shows a diagram of the installation with the apparatus, divided in the upper part into two zones.

Установка включает в себ  -аппарат /, теплообменник 2 дл  нагревани  воздуха, теплообменник 3 дл  нагревани  SO2, фильтр-конденсатор 4 серы, фильтр 5, воздуходувку 6 и газодувку 7. В нижней части аппарата / расположена зона А получени  SOz, верхн   часть аппарата 1 разделена на зону Б окислени  РезО4 и зону В получени  серы.The installation includes an appliance /, a heat exchanger 2 for heating the air, a heat exchanger 3 for heating the SO2, a sulfur filter condenser 4, a filter 5, a blower 6 and a gas blower 7. At the bottom of the device / there is a zone A for producing SOz, the upper part of the device 1 divided into the B zone of ResO4 oxidation and the B zone of sulfur production.

Колчедан подаетс  питателем в зону В, где в псевдоожиженном слое происходит термическа  воЗГонка серы и взаимодействие части FeS с SOs- Псевдоожиженный слой создаетс  сернистым газом, поступающим из зоны А. Полученна  газова  смесь, состо ща  из паров серы и SOz, направл -етс  в тёплйобменник 2, где отдает свое тепло воздуху , поступающему в зону Б. Далее газова  смесь проходит фг1 ьтрконденсатор 4 дл  выделени  серы, а оставщийс  SO после охлаждени  или без охлаждейи , в зависимости от конструкции газодувки 7/ засасываетс  последней и после нагревани  в теплообменнике 3 подаетс  в зону А дл  создани  в ней псевдоожиженного сло . В зону А поступает огарок, состо щий из части FeS и этот огарок взаимодействует с окисью железа с выделением SO, необходимого дл  взаимодействи  в зоне В. РезО4 из зоны А транспортируетс  воздухом в зоPyrite is supplied by a feeder to zone B, where sulfur is heated thermally and a part of FeS interacts with SOs in the fluidized bed. The fluidized bed is created by sulfur dioxide coming from zone A. The resulting gas mixture, consisting of sulfur vapor and SOz, is sent to the heat exchanger 2, where it gives off its heat to air entering zone B. The gas mixture then passes fg1 condenser 4 to release sulfur, and the remaining SO after cooling or without cooling, depending on the design of the blower 7 /, is sucked last and after heating. Vani in heat exchanger 3 is supplied to zone A for providing a fluidized bed therein. Zone A receives a calcine consisting of a part of FeS and this calcine reacts with iron oxide with the release of SO necessary for interaction in zone B. ResO4 from zone A is transported by air to the zone.
