Description
Technical field
Device and technique that raw sulphur prepares sulfur dioxide gas can be continuously burned the present invention relates to a kind of, belongs to desulfurization by-product
The technical field of product processing.
Background technology
Sulphur, typically refers to ripe sulphur or crystallization sulphur or elemental sulfur, is one of sulfur dioxide or the primary raw material of gas washing in SA production.
Under normal temperature, sulphur is solid, and property is crisp, frangible, good dispersion, is easily burned.Raw sulphur, commonly referred to as sulphur cream or sulphur mud or sulphur slag, it is non-
Crystalline form shape, sulfur content is low, and aqueous component is high, and easy mobility is amorphous, and hardly possible is burned.Therefore, sulfuric acid plant etc. produces sulfur dioxide
Factory does not use raw sulphur to make raw material.Domestic coke-oven plant's coal gas desulfurization decyanation uses Wet Catalytic Oxidation Method sulfur removal technology mostly,
The sulphur bubble processing approach of generation has two kinds, and one is formed into melting sulphur, and another is the raw sulphur of production.Because of the process steam of melting sulphur processed
High energy consumption, cost is high, and sulphur is second-rate, and the market price is not also high.So most of raw sulphur of coke-oven plant's selection production.Because of raw sulphur
Market value it is extremely low, be difficult to sell again, and take landfill, air storage the means such as is discarded and handled, this just makes to environment
Into secondary pollution.
At present, raw sulphur yield is quite big, and the sulphur for removing and reclaiming from coke-stove gas every year has 53.6 ten thousand tons, wherein 60% is
Unprocessed raw sulphur, is converted to about 64.32 ten thousand tons/year to 700,000 tons/year of raw sulfur content.Disposal and economy for these life sulphur
It is to solve the unique channel that raw sulphur source source is continuously increased the pressure caused to environment using feasible method is found.
The heat of fusion of sulphur is 49.8 kJ/kg (rhombus sulphur) and 38.5 kJ/kg (monoclinic sulfur), and the specific heat of liquid sulfur is
0.96 kJ/kg DEG C, density is 1799~1770kg/m3.When raw sulphur is burned, melt after sulphur therein is heated, easy trickling is simultaneously
Form the flame of trickling.Raw sulphur is directly burned, because its water content is high, sulfur content is low, often burns insufficient.In the prior art,
Have raw sulphur processing purification in the technique burned again after the sulphur of high content, such as reclaim and purify sulphur using extraction process
Sulphur in mud, sulphur cream, the processing step is complicated, and power consumption is high, and production cost is high, the low yield of gained sulphur.Also have raw sulphur
It is put into after sulfur melting kettle melts sulphur and goes deimpurity technique, the technique is to add sulphur mud, sulphur cream to sulfur melting kettle, by sulphur mud, sulphur cream
In sulphur be all molten into liquid, energy consumption of the technique during molten sulphur is excessive, greatly increases production cost.
Sulphur mud, the harmless treatment of sulphur cream are the important components of desulfurization recycle section, are produced from fire coal after desulfurization
The byproducts such as the sulphur mud, the sulphur cream that go out, sulfur purity is low, of poor quality, sale is difficult, in addition to the sulphur for boiling low-purity, at present also
It is used without other relatively good methods.At present, raw sulphur yield is quite big, removes and reclaims from coke-stove gas every year
Sulphur have 53.6 ten thousand tons, wherein 60% is unprocessed raw sulphur, be converted to about 64.32 ten thousand tons/year to 700,000 tons of raw sulfur content/
Year.Feasible method is found in disposal and economic utilization for these life sulphur, and the raw sulphur source source of solution is continuously increased causes to environment
The unique channel of pressure.
The content of the invention
It is an object of the invention to provide one kind for above-mentioned defect can continuously burn raw sulphur preparation titanium dioxide
The device and technique of sulphur gas.The handling process is simple and easy to apply, and production cost is low, and raw sulphur can be made full use of to greatest extent.
The technical solution adopted by the present invention is as follows.
It is a kind of continuously to burn the device that raw sulphur prepares sulfur dioxide gas, including the first feed system, drying system,
Two feed systems, CIU, dreg removing system, gas gathering system.
First feed system includes the first loading hopper, and the bottom opening of the first loading hopper is filled provided with extruding
Put.The purpose of pressurizing unit is set to be raw sulphur extruding into strips or block, it is quantitative, continuous to input life to drying system
Sulphur.
The drying system includes drying chamber, the second transmission device, drying unit；Drying chamber is provided with charging aperture, exhaust outlet；
The charging aperture of drying chamber is connected with the bottom opening of the first loading hopper；Drying unit includes hot blast spray nozzle, the second transmission dress

When raw sulphur is burned, melt after sulphur therein is heated, easily trickle and formed the flame of trickling.Therefore, if using
Conventional chain furnace burns raw sulphur, easily blocks screening, and burning ventilation condition is bad, causes to burn insufficient.Meanwhile, screening is blocked up
Plug is easily caused the first transmission device and rotates difficult, and because body of heater is provision for sealing, cleaning is difficult, takes time and effort.In addition, trickling
Flame the bottom of body of heater is easily also dropped into from the gap of screening, easily make the part distortions such as screening or burn out, make easily
The first transmission device is caused to rotate difficult, equipment life, operational efficiency are greatly reduced.
The burning in addition, liquid sulfur catches fire at 250 DEG C.Sulphur gasifies rapidly when temperature is high, if it not and burn if be pulled away,
When cooling down afterwards, and solid is condensed into again, be deposited in pipeline equipment, or even by pipeline blockage.To avoid Sulfur distillation stifled
Pipeline is filled in, incineration temperature is unsuitable too high.SO2 oxidations can generate SO3, and SO3 generation is decided by that the temperature and oxygen content of gas exist
700~800 DEG C and it is oxygen-containing more when carry out comparatively fast., should be fast by the gas for burning generation to reduce this harmful reaction
Quickly cooling but enters the excess air of sulfur burner with reduction.In addition, metal and its oxide have obvious catalytic action to this reaction.
This reaction of cast iron incinerator is weaker, and more durable.
The purpose for setting auxiliary incinerator is, provides certain amount of air to burn, makes that it is fully burned and peroxide does not burn
Burn；Make to give birth to sulphur and jump in screening to reach abundant burning, prevent from giving birth to melting after sulphur is burned produce trickling flame fall on screening with
