Description
Technical field
The present invention relates to a kind of burning process device of living sulphur of wet desulphurization generation, be specifically related to a kind of device that living sulphur prepares sulfurous gas that is used for directly burning.
Background technology
Sulphur typically refers to ripe sulphur or crystallization sulphur or elemental sulfur, is one of main raw material of sulfurous gas or gas washing in SA production.Under the normal temperature, sulphur is solid, and property is crisp, and is frangible, good dispersity, easy firing.Give birth to sulphur, be commonly referred to sulphur cream, the amorphous shape, sulphur content is low, contains the amount of moisture height, and easy mobility is amorphous, difficult to burn.Therefore, the factory of production sulfurous gas such as vitriol works does not adopt living sulphur to make raw material.Catalytic wet oxidation method sulfur removal technology is adopted in the coal gas desulfurization decyanation of domestic coke-oven plant mostly, and the sulphur bubble processing approach of generation has two kinds, and the one, make melting sulphur, another kind is to produce to give birth to sulphur.Because of the process steam energy consumption height of system melting sulphur, the cost height, sulphur is second-rate, and market value is not high yet.So sulphur is selected to produce by most of coke-oven plants.Because of the marketable value of giving birth to sulphur is extremely low, be difficult for again selling, and take landfill, air storage, means such as discarded are handled, and this just causes secondary pollution to environment.
At present, it is quite big to give birth to sulphur output, and the annual sulphur that removes and reclaim from coke-oven gas has 53.6 ten thousand tons, and wherein 60% is unprocessed living sulphur, be converted to living sulfur content about 64.32 ten thousand tons/year to 700,000 tons/year.Seeking feasible method for these disposal and economic utilizations of giving birth to sulphur, is to solve to give birth to the unique channel that sulphur increases the pressure that causes to environment continually.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the purpose of this invention is to provide a kind of device that living sulphur prepares sulfurous gas that is used for directly burning, in order to overcome the technical problem of the nonflammable and incomplete combustion of living sulphur, with give birth to sulphur amorphous, can flow, nonflammable proterties, change into moulding, mobile, incendive proterties, realize giving birth to flammable, the inflammable purpose of sulphur.
