The purpose of this utility model is to improve the deficiencies in the prior art, provides a kind of equipment simple, less investment, and the continuous sulfur recovery sulfur melting kettle that treatment capacity is big, separation efficiency is high.

For achieving the above object, the utility model is taked following design:

This sulfur melting kettle includes jacketed type still and bell jar, sets firmly the notch plate of a pan bottom shape on described still inwall, and still is divided into two isolated up and down spaces, and the space of described notch plate and still upper end constitutes a separator; Described bell jar is fixedly arranged on the below of described separator, is provided with an annular gap between itself and the still inwall; Upcast is established in the upper end of bell jar, the upcast lower end be fixed on the bell jar and with bell jar in link up, its upper end is passed described notch plate and is entered separator, and affixed with notch plate; Set firmly the upper end of downtake in the following recess perforate of described notch plate, the lower port of described downtake penetrates in the bell jar and by the bell jar sidewall and passes, and is located at the annular space place that described bell jar and still inwall form; The top perforate of described separator, sealed attachment feed-pipe upper end, its lower end are passed described notch plate and are placed described bell jar top; Perforate on the upper end still wall of described separator, the sealed attachment liquid outlet.

When using this molten stream still to work, after sulfur-containing liquid flow to the bell jar top of still lower space by described feed-pipe, the sulphur foam is flowed downward by the gap that the bell jar laminating enters bell jar and still wall, the steam heat of steam jacket and enter in the bell jar under the effect of mobile hot liquid, the sulphur foam that is dispersed into thin layer reaches 60-90 ℃ soon, the small sulfur granules that sticks on the foam is assembled increase along with foamy breaks, and sinks and and solution separating.The hot solution proportion that separates behind the sulphur becomes littler than sulphur, along floating in the bell jar, enter separator from upcast, separator does not have the thermal source heating, and solution is static relatively at this, be deposited to described separator bottom with a small amount of sulfur granules that comes on the hot solution, solution is further separated, and is last, and clear liquid is outside liquid discharge pipe is discharged still, the sulphur that separates in separator enters the gap of bell jar and still wall by downtake, with the sulphur foam that advances still to the still bottom sediments.The separation deposition process of sulphur also is constantly to dewater to be heated process, when the solution of discharging has sulfur granules, show that the sulphur layer in the still reaches the height of putting sulphur continuously, at this moment, opens the insulation sulfur discharging valve, because the bottom of still and reinforcement sulfur melting tube and insulation sulfur discharging valve all have the design of steam heating chuck, under the heat effect of steam, make still at the bottom of temperature remain 120-130 ℃, isolating sulphur sinks to the high-temperature zone, just become molten state and be easy to flowing fluid sulphur, successfully in still, emit.Behind naturally cooling, become block sulfur product.When sulphur foam abundance, this process can be carried out continuously.If the sulphur foam is on the low side, this process can be interrupted and be carried out.
