Abstract
The utility model discloses a utilization system for tailings in sulfuric acid preparation, which comprises a disk type feeding machine, a ball mill, a setting basin, a water reservoir and an acidic water pump, wherein the discharge end of the disk type feeding machine is connected with the feed end of the ball mill; the discharge end of the ball mill is connected with the setting basin; the setting basin is communicated with the water reservoir; and the acidic water pump is arranged in the water reservoir and is connected with the feed end of the ball mill through a pipeline. According to the utility model, lump pyrite screened out of smashed pyrite and tailings filtered out of melted sulfur for acid preparation are fed by the disk type feeding machine into the ball mill to be smashed to produce ore slurry which enters the setting basin to be subjected to solid-liquid separation; and separated sulfur ore on the lower layer is dried and then fed into a fluidized bed furnace to be roasted to prepare sulfuric acid, so as to realize reutilization of sulfur resources and reduce environment pollution.
Description
Technical field
The utility model relates to the gas washing in SA production technical field, and more particularly, the tailings that relates in particular in a kind of sulfuric acid preparation utilizes system.
Background technology
Ferric sufide and brenstone all is main raw materials of preparation sulfuric acid, yet, lump ore (tailings diameter 10～50mm) and acid production with sulphur molten sulphur filter after of sulfurous iron ore after crushing and screening, sulphur content is about 70%, have large, the intractability high of hardness, can not be directly used in production, do not process for a long time being deposited in factory building, not only caused the serious waste of sulphur resource, gone back occupied ground and cause environmental pollution.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide the tailings in a kind of sulfuric acid preparation to utilize system, lump ore and acid production with sulphur molten sulphur the tailings filter after of sulfurous iron ore after crushing and screening recycled, realized the regeneration of sulphur resource, environmental contamination reduction.
For achieving the above object, tailings in the sulfuric acid preparation provided by the utility model utilizes system, comprise rotary disc feeder, ball mill, settling bowl, water reservoir and acid water pump, the discharge end of described rotary disc feeder is connected with the feed end of ball mill, the discharge end of ball mill connects settling bowl, settling bowl is connected with water reservoir, and acid water pump is arranged in the water reservoir, by the feed end of pipeline connection ball grinding machine.
The utility model is delivered to lump ore and acid production with sulphur molten sulphur the tailings filter after of sulfurous iron ore after crushing and screening in the ball mill and is pulverized by rotary disc feeder, the ore pulp that produces after pulverizing enters settling bowl and carries out solid-liquid separation, boiling roaster is sent into after drying as preparation sulfuric acid in the lower floor sulphur ore deposit of separating, realize the regeneration of sulphur resource, environmental contamination reduction with this; Supernatant liquid then enters water reservoir by the overflow mode, controls simultaneously the acidity of clear liquid in the pond, after guaranteeing not corrode ball mill, by acid water pump clear liquid is delivered to ball mill again and recycles, to reduce sewage load, effective saving water resource.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the 1-rotary disc feeder; The 2-ball mill; The 3-settling bowl; The 4-water reservoir; The acid water pump of 5-.
Embodiment
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not consist of any restriction of the present utility model.
Consult shown in Figure 1ly, the tailings in the utility model sulfuric acid preparation utilizes system, comprises rotary disc feeder 1, ball mill 2, settling bowl 3, water reservoir 4 and acid water pump 5.Wherein, the discharge end of rotary disc feeder 1 is connected with the feed end of ball mill 2, and the discharge end of ball mill 2 connects settling bowl 3, and settling bowl 3 is connected with water reservoir 4, and acid water pump 5 is arranged in the water reservoir 4, by the feed end of pipeline connection ball grinding machine 2.
Groundwork process of the present utility model is: lump ore and acid production with sulphur molten sulphur the tailings filter after of sulfurous iron ore after crushing and screening delivered to rotary disc feeder 1 after reclaiming, by rotary disc feeder 1 equably to ball mill 2 feed, utilize ball mill 2 that lump ore and tailings are pulverized, the ore pulp that produces after pulverizing enters settling bowl 3, with settling methods the ore pulp that grinds is carried out solid-liquid separation, the lower floor sulphur ore deposit of separating is delivered to sends into boiling roaster as preparation sulfuric acid after the stockyard Exposure to Sunlight of sulphur ore deposit is dried, realize the regeneration of sulphur resource, environmental contamination reduction with this; Supernatant liquid then enters water reservoir 4 by the overflow mode, adopt the mode of Real Time Monitoring to control the acidity of water reservoir 4 interior clear liquids, guarantee not corrode ball mill 2 after, by acid water pump 5 clear liquid is delivered to ball mill 2 again and recycles, to reduce sewage load, effective saving water resource.
Claims (1)
