Sulfur particle settling agent used for desulfurization solution in wet oxidization process

The invention belongs to the technical field of gas purification, in particular to a sulfur particle settling agent used for desulfurization solution in a wet oxidization process. The sulfur particle settling agent is a mixture of a nonionic surfactant, C7-C18 saturated straight chain alcohol, oligosaccharides and high valent metal salts. The sulfur particle settling agent can make a sulfur foam layer in the desulfurization solution eliminated and sulfur particles uniformly distributed in the desulfurization solution, promotes the sulfur particles condensed and polymerized to form particular clusters, and makes the sulfur particles quickly settled and separated. Compared with other sulfur separating methods, the sulfur particle settling agent can separate out high-purity sulfur on the basis of saving energy and reducing consumption, and prolong the running period of the whole desulfurization system.
