Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania granulek siarki z dodatkiem inhibitora wydzielania siarkowodoru, którym jest odpad po flotacji rudy miedzi, zmniejszający wyziewy siarkowodoru, a zawarta w granulce siarka zmniejsza ilość użytego asfaltu drogowego. Granulki te stosowane są zwłaszcza jako dodatek do mieszanek drogowych, składających się z kruszyw mineralnych oraz lepiszcza asfaltowosiarkowego, które to mieszanki używane są do budowy lub remontu nawierzchni drogowych. Granulki siarki z dodatkiem inhibitora wydzielania siarkowodoru otrzymuje się w mieszalniku dwuwałowym o objętości V 2 - 4 m3 ogrzewanym olejem grzewczym w temperaturze 125°C, w czasie 20 minut z prędkością obrotową mieszadła 50 obr/min. miesza się płynną masę o składzie 70 - 80% wagowych siarki odpadowej z 20 - 30% wagowych odpadu po flotacji rudy miedzi, płynną zawartość mieszalnika kieruje się do granulacji na granulator bębnowy, a następnie uformowane granulki spadają na transporter z taśmą stalową chłodzoną wodą, na którym schładzają się do postaci stałej, a następnie konfekcjonuje i dostarcza do producentów mieszanek mineralnoasfaltowych, stosowanych w drogownictwie do remontu i wykonania dróg jako dodatek do tych mieszanek, zmniejszając w nich ilość użytych asfaltów drogowych jak ilość wydzielanego siarkowodoru.The subject of the application is a method for obtaining sulfur granules with the addition of a hydrogen sulfide secretion inhibitor, which is waste from copper ore flotation, reducing hydrogen sulfide fumes, and the sulfur contained in the granule reduces the amount of used asphalt. These granules are used in particular as an additive to road mixtures consisting of mineral aggregates and asphalt-sulfur binder, which mixtures are used for the construction or renovation of road surfaces. Sulfur granules with the addition of an hydrogen sulfide release inhibitor are obtained in a two-shaft mixer with a volume of V 2 - 4 m3 heated with heating oil at a temperature of 125 ° C for 20 minutes at a rotational speed of 50 rpm. a liquid mass composed of 70-80% by weight of waste sulfur is mixed with 20-30% by weight of waste from copper ore flotation, the liquid content of the mixer is directed to granulation on a drum granulator, and then the formed granules fall onto a conveyor with water-cooled steel belt, which cool to solid form, and then pack it and deliver to producers of asphalt mixtures used in road construction for renovation and construction of roads as an addition to these mixtures, reducing the amount of used asphalt road as the amount of hydrogen sulfide released.
