Process and equipment for melting sulfur

The invention relates to the field of chemical production separation and smelting, in particular to a process and equipment for melting sulfur. The technical scheme includes that the process comprisesfeeding sulfur foam into a foam tank and pumping the sulfur foam into a filter press by a foam pump connected with the foam tank; dividing the sulfur foam in the filter press into two portions including desulfurization liquid and sulfur paste with 20%-30% of desulfurization liquid, allowing the desulfurization liquid to flow into a mother liquor circulating tank, allowing the sulfur paste to flowinto a sulfur melting kettle, allowing the sulfur paste to be heated by high-temperature steam at the temperature of 120-130 DEG C in the sulfur melting kettle, melting the heated sulfur paste to obtain liquid-state sulfur and volatilizing most of the desulfurization liquid in the sulfur paste in heating procedures; draining the molten liquid-state sulfur in the sulfur melting kettle into an ironbox via a sulfur discharge
