Description of drawings
Fig. 1 is the planar structure schematic diagram of the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this continuous sulfur melting still is put the sulphur device automatically and is comprised: kettle 1, the upper end of kettle 1 is provided with sulphur slurries inlet 2, the top of kettle 1 is provided with clear liquid outlet 3, the lower end of kettle 1 is provided with the molten sulfur outlet, this molten sulfur outlet connects desulphurization pipeline 4, and the position near the molten sulfur outlet on the desulphurization pipeline 4 is provided with valve 5, and the tail end of desulphurization pipeline 4 connects molten sulfur storage tank 6.
Wherein, after desulphurization pipeline 4 was drawn downwards from molten sulfur outlet, vertical-horizontal bent upwards vertical again bending behind the segment distance a, horizontal again bending b to the height H, and bending vertically downward at last makes desulphurization pipeline 4 be connected into molten sulfur storage tank 6.
During use, the sulphur slurries of about 0.3Mpa are sent in the kettle 1 from the sulphur slurries inlet 2 of continuous sulfur melting still, add hot melt sulphur through sulfur melting kettle chuck low pressure steam.Because the molten sulfur density of fusion is bigger, molten sulfur is settled down to autoclave body bottom gradually.Liquid in the kettle 1 is divided into three layers: the upper strata is isolated clear liquid, about 90 ℃ of its temperature; The molten sulfur of lower floor for producing, about 140 ℃ of temperature; Middle be unsegregated mixed liquor still, the temperature of mixed liquor is about 100 ℃.
