Description

Technical Field

[0001] The utility model relates to the field of sulfur incinerator equipment, in particular to a sulfur incinerator unloading device. Background Art

[0002] The sulfur incinerator is the core equipment for preparing sulfuric acid. During the acid production process, sulfur powder enters the sulfur incinerator for combustion. The sulfur dioxide flue gas generated by the reaction is purified, converted and absorbed to eventually generate 93% or 98% concentrated sulfuric acid products. Production requires that all sulfur powder must be dispersed and enter the sulfur incinerator for combustion to ensure that the sulfur powder is smoothly fed in and does not burn in the feeding device to produce dilute acid and corrode the chute.

[0003] However, the two sides of the existing sulfur incinerator silo are curved, and the arc of the two sides is small. In actual production, it is found that when unloading, the sulfur dry powder is very easy to be stored in the arc dead corners on both sides of the silo, and the dispersion effect is not good, resulting in that all the sulfur dry powder cannot enter the sulfur incinerator. Over time, a large amount of material accumulation will be formed in the unloading device, and the combustion of these accumulated materials will produce dilute acid to corrode the chute.

[0004] In addition, the side air inlet of the existing sulfur incinerator is circular and located at the lower part of the bottom plate of the silo. When unloading, dry sulfur powder is easy to fall into the side air inlet or the blind area of ​​the side air inlet, thereby forming accumulated material, which further burns and corrodes the unloading device and the side air inlet, resulting in a sudden reduction in the life of the unloading device. Shutdown for inspection and replacement not only greatly reduces production efficiency, but also consumes time and materials, increasing production costs. Utility Model Content
