Abstract
The utility model discloses a boiling furnace taking sulfur as a raw material. The boiling furnace comprises a furnace body, a sulfur material cabin and a feeding conveying belt, wherein the feeding conveying belt is used for conveying a material in the sulfur material cabin into the furnace body; a wear-resistant material cabin is formed above the feeding conveying belt, and is provided with a feed opening; and a discharging valve is arranged on the feed opening. Compared with a way for taking iron pyrite as a raw material, the boiling furnace has the advantages that: sulfur is taken as a raw material, so that the yield is increased by 10 percent correspondingly, and the production environment and finial product quality are improved.
Description
Technical field
The utility model relates to the equipment for preparing sulfurous gas, and specifically a kind of is the fluidizing furnace of raw material with sulphur.
Background technology
At the system sulfuric acid industry, traditional fluidizing furnace is to be that raw material is produced SO2 with sulfurous iron ore or pyrite concentrate.Because of sulfurous iron ore is granular or the powdered raw material, so contain a large amount of dust in the furnace gas, need stage purification equipment furnace gas is purified, the production link more complicated, and also dustiness is high in the production environment.Be raw material when producing with sulphur, can relax greatly,, thereby can not impact the vitriolic quality product even, also can be removed at cleaning section because more impurity is arranged in the sulphur to the purity requirement of sulphur raw material.Therefore, use sulphur both can produce qualified sulfuric acid product, also can reduce the vitriolic production cost as raw material.But fluidizing furnace will guarantee that at first good boiling could guarantee good burning state, and will guarantee good boiling, must in stove, keep certain thickness immovable bed.When being raw material with the sulfurous iron ore, immovable bed is to lean on the sulfurous iron ore of constantly bringing the certain particle size in the stove in the material into to keep, and is raw material with sulphur, and the material long term wear in the immovable bed and can not get replenishing can influence the works better of fluidizing furnace.
The utility model content
For solving fluidizing furnace in the prior art, with sulphur the fluidizing furnace of raw material but the utility model provides a kind of ordinary production in technical problem that can't ordinary production during for raw material with sulphur.
The utility model is achieved in that
A kind of is the fluidizing furnace of raw material with sulphur; Comprise body of heater, sulphur feed bin and feeding web; Said feeding web with the mass transport in the said sulphur feed bin to body of heater; Above feeding web, be provided with the wear-resistant material feed bin, said wear-resistant material feed bin has feed opening, on the said feed opening blow-off valve is installed.
The utility model is provided with the wear-resistant material feed bin above feeding web, and on its feed opening, blow-off valve is installed, and in the fluidizing furnace working process, this blow-off valve normality belongs to closing condition.Have only after the wearing and tearing of the material in the immovable bed, just open the blow-off valve of wear-resistant material feed bin, make wear-resistant material in feeding web is delivered to the boiling body of heater, make the immovable bed of wearing and tearing obtain replenishing and keeping normal thickness, with the works better of assurance fluidizing furnace.
The beneficial effect of the utility model is:
1, be that the fluidizing furnace of raw material is in combustion processes with the sulfurous iron ore; Ferro element oxidation and the certain oxygen amount of other oxygen consumption reaction needed consumption; So send into the oxidation that oxygen in the fluidizing furnace is not used for element sulphur fully, have 10% oxygen to be used for above-mentioned ferro element oxidation and the reaction of other oxygen consumption approximately.And be raw material with sulphur, oxygen only is used for the oxidation of element sulphur, sends into same oxygen in the fluidizing furnace, and effecting reaction increases by 10% approximately, therefore, and is that raw material is compared with the sulfurous iron ore, is that raw material can make the also corresponding raising 10% of output with sulphur.
2, production environment improves
Fluidizing furnace is raw material with the sulfurous iron ore, and one ton of sulfurous iron ore of every burning produces 0.6 ton slag approximately, no matter adopts which kind of mode to carry, and all can cause dust pollution phenomenon in various degree, causes operating environment more abominable.And be raw material with sulphur, do not produce waste residue, just can not cause environmental pollution yet.
3, improve the sulfuric acid product quality
Owing to contain metallic elements such as a certain amount of copper, iron, zinc, lead in the sulfurous iron ore, produce a large amount of ash contents in the combustion processes again, although the processing of process cleaning section can not be removed, so can contain above-mentioned impurity in the finished product sulfuric acid fully.And be raw material with sulphur, above-mentioned impurity is almost nil, even a certain amount of impurity is arranged, because content is low, it is much little that the cleaning section relative load is wanted, and decontamination effect improving is also much higher, so impurity is relatively low in the sulfuric acid.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1; With sulphur is the fluidizing furnace of raw material; Comprise body of heater 1, sulphur feed bin 2 and feeding web 3, said feeding web to body of heater, is characterized in that above feeding web, being provided with wear-resistant material feed bin 4 with the mass transport in the said sulphur feed bin; Said wear-resistant material feed bin has feed opening 5, on the said feed opening 5 blow-off valve is installed.
