Description
Technical field
This utility model relates to a kind of can burning raw sulfur continuously and preparing device and the technique of sulfur dioxide gas, belongs to the technical field that desulfuration byproduct processes.
Background technology
Sulfur, it is common that refer to ripe sulfur or crystallization sulfur or elemental sulfur, is one of the primary raw material of sulfur dioxide or gas washing in SA production.Under room temperature, sulfur is solid, and property is crisp, frangible, and good dispersion easily burns.Raw sulfur, is commonly referred to sulfur cream or sulfur mud or sulfur slag, amorphous shape, and sulfur content is low, and moisture component is high, and easy mobility is amorphous, difficult burning.Therefore, the factory of the production such as sulfuric acid plant sulfur dioxide does not adopt raw sulfur to make raw material.The coal gas desulfurization decyanation of domestic coke-oven plant adopts Wet Catalytic Oxidation Method sulfur removal technology mostly, and the sulfur bubble of generation processes approach two kinds, and one is formed into melting sulfur, and another kind is to produce raw sulfur.Because the process steam energy consumption of melting sulfur processed is high, cost is high, and sulfur is second-rate, and the market price is not high yet.So most of coke-oven plants select to produce raw sulfur.The means such as the market value because giving birth to sulfur is extremely low, not easily sells again, and takes landfill, air storage, discarded process, and this just causes secondary pollution to environment.
At present, raw sulfur yield is quite big, and the sulfur removing from coke-stove gas every year and reclaiming has 53.6 ten thousand tons, and wherein 60% is unprocessed raw sulfur, is converted to about 64.32 ten thousand tons/year to 700,000 tons/year of raw sulfur content.Feasible method is found in disposal and economic utilization for these raw sulfur, is solve raw sulfur to be added to the unique channel of the pressure that environment causes continually.
The fusing heat of sulfur is 49.8kJ/kg (rhombus sulfur) and 38.5kJ/kg (monoclinic sulfur), and the specific heat of liquid sulfur is 0.96kJ/kg DEG C, and density is 1799～1770kg/m3.When raw sulfur burns, sulfur therein melts after being heated, it is easy to trickles and forms the flame of trickling.Directly burning raw sulfur, owing to its water content is high, sulfur content is low, often burns insufficient.In prior art, having the technique carrying out burning after raw sulfur processing is purified the sulfur in high-load again, such as the sulfur adopting extraction process to reclaim and purify in sulfur mud, sulfur cream, this processing step is complicated, and power consumption height, production cost is high, and the productivity of gained sulfur is low.Also having after life sulfur is put into the molten sulfur of sulfur melting kettle and go deimpurity technique, this technique is sulfur mud, sulfur cream to be added to sulfur melting kettle, and the sulfur in sulfur mud, sulfur cream is all molten into liquid, and this technique energy consumption in molten sulfur process is excessive, is greatly increased production cost.
Sulfur mud, sulfur cream harmless treatment be the important component part of desulfurization recycle section, the side-products such as the sulfur mud produced after desulfurization from fire coal, sulfur cream, sulfur purity is low, of poor quality, sell difficulty, except the sulfur boiling low-purity, there is presently no other reasonable methods and be used.At present, raw sulfur yield is quite big, and the sulfur removing from coke-stove gas every year and reclaiming has 53.6 ten thousand tons, and wherein 60% is unprocessed raw sulfur, is converted to about 64.32 ten thousand tons/year to 700,000 tons/year of raw sulfur content.Feasible method is found in disposal and economic utilization for these raw sulfur, is solve raw sulfur to be added to the unique channel of the pressure that environment causes continually.
