Underwater sulfur granulation and waste gas treatment system

The invention discloses an underwater sulfur granulation and waste gas treatment system. The system comprises a granulation main machine, and a heat preservation forming pool, a liquid sulfur inlet pipeline, an anti-splashing distribution device, a waste gas collection cover and a waste gas washing and spraying device which are arranged above the granulation main machine. A drying dehydration device, a water-solid separation device, a fine powder sulfur spiral conveyor, a sulfur melting device and a circulating water return device are arranged below the granulation main machine. According to the underwater sulfur granulation and waste gas treatment system provided by the invention, the liquid sulfur can quickly become spherical particles in a granulation system, the spherical particles aresmooth in surface, uniform in granularity, extremely low in water content and high in production efficiency, and waste gas discharged in the liquid sulfur forming process is treated, so that the operation environment is grea
