[0016] The sulfur melting kettle device described in the present invention is further described in detail below in conjunction with preferred embodiments.

[0017] like Figure 1 、 Figure 2As shown, a molten sulfur kettle device includes a molten sulfur kettle cylinder 1, a cylinder feed port 11 is provided on the top of the molten sulfur kettle cylinder 1, a desulfurization liquid outlet 12 is provided on the molten sulfur kettle cylinder 1 on one side of the cylinder feed port 11, and a sulfur outlet 13 is provided on the bottom of the molten sulfur kettle cylinder 1. A partition 2 is provided at the upper end of the molten sulfur kettle cylinder 1, and the partition 2 plays a role of separation, separating the molten sulfur kettle cylinder 1 above and below the partition 2. A partition feed hole 21 and a plurality of partition reflux holes 22 are provided on the partition 2, and the cylinder feed port 11 and the partition feed hole 21 are connected through a feed pipe 4. In this embodiment, the cylinder feed port 11, the partition feed hole 21, and the feed pipe 4 are located on the central axis of the molten sulfur kettle cylinder 1, and the feed pipe 4 is vertically arranged.

[0018] A guide tube 5 is provided in the sulfur melting kettle cylinder 1 below the partition 2. The guide tube 5 includes a guide tube body 51. The bottom of the guide tube body 51 is connected to the sulfur melting kettle cylinder 1. The top of the guide tube body 51 is provided with a conical guide tube top 52 that is inclined downward from the middle to the surroundings, and the outer end of the guide tube top extends to the guide tube body. In this embodiment, the angle θ formed by the generatrix of the cone forming the guide tube top 52 and the horizontal plane is 15°. The purpose of setting θ to 15° is to promote the dispersion of materials falling from above onto the guide tube top 52 on the guide tube top 52, and then move outward along the guidance of the guide tube top 52, which can greatly improve the uniformity of distribution on the guide tube top 52.

[0019] A guide gap 10 is formed between the outer wall of the guide tube body 51 and the inner wall of the sulfur melting kettle body 1. In this embodiment, the lower end of the guide tube body 51 is open, and the width of the guide gap 10 formed between the outer wall of the guide tube body 51 and the inner wall of the sulfur melting kettle body 1 is 60-70 mm.

[0020] A plurality of reflux pipes 521 connected to the interior of the guide tube 5 are provided on the top 52 of the guide tube. The reflux pipes 521 correspond to the baffle reflux holes 22 one by one. The upper end of each reflux pipe 521 is connected to the bottom of the corresponding baffle reflux hole 22. The lower end of the guide tube body 51 is connected to the molten sulfur kettle cylinder 1. In this embodiment, there are four baffle reflux holes 22 and four reflux pipes 521. The four baffle reflux holes 22 are evenly spaced around the baffle feed hole 21. The reflux pipes 521 are vertically arranged below the baffle reflux holes 22. A plurality of ribs 511 are spaced apart on the outer wall of the lower end of the guide tube body 51. The lower end of the guide tube body 51 is fixed to the inner wall of the molten sulfur kettle cylinder 1 through the ribs 511.

[0021] A heating jacket 6 is provided on the outer wall of the molten sulfur kettle cylinder 1 below the draft tube body 51. The heating jacket 6 is provided with a heating medium input pipe 61 and a heating medium output pipe 62. The heating medium can be steam.

[0022] In order to improve the rigidity and stability of the sulfur melting kettle cylinder 1, a plurality of reinforcing rings 7 are arranged at intervals on the inner wall of the sulfur melting kettle cylinder 1 below the guide tube 5. Usually, three to four reinforcing rings 7 are arranged.

[0023] The lower end of the sulfur melting kettle cylinder 1 is a tapered section cylinder 14 whose diameter gradually decreases from top to bottom. The heating jacket 6 extends along the tapered section cylinder 14 to the sulfur outlet 13.

[0024] The working principle is as follows: the foamy material formed by the desulfurization liquid and elemental sulfur falls onto the top of the guide cylinder 52 through the cylinder feed port 11, the feed pipe 4, and the partition feed hole 21. Under the guidance of the guide cylinder top 52, the material enters the guide gap 10, and then is guided by the guide gap 10 to fall downward along the inner wall of the molten sulfur kettle cylinder 1. When the material falls into the position area of ​​​​the heating jacket 6, under the action of the heating medium in the heating jacket 6, the material is heated, and the heated desulfurization liquid foam bursts, and the elemental sulfur is separated from the desulfurization liquid foam. The elemental sulfur precipitates downward and is guided to the sulfur outlet 13 through the conical section cylinder 14 at the lower end of the molten sulfur kettle cylinder 1 and discharged outward. The desulfurization liquid continuously accumulates in the sulfur melting kettle cylinder 1. As the liquid level of the desulfurization liquid continues to rise, the desulfurization liquid will enter the space above the partition 2 through the reflux pipe 521 on the top of the guide cylinder 52 and the partition reflux hole 22, and then be discharged outward from the desulfurization liquid outlet 12.

[0025] The advantages of the present invention are: 1. The structure is simple, and the guide tube plays a good role in guiding the material. It allows the sulfur material attached to the desulfurization liquid foam to move from the guide gap 10 outside the guide tube, and the elemental sulfur separated from the desulfurization liquid moves downward and is discharged from the sulfur outlet 13. The desulfurization liquid separated from the elemental sulfur flows out through the interior of the guide tube through the reflux pipe and the desulfurization liquid outlet 12, thereby achieving effective separation of the elemental sulfur material and the desulfurization liquid, and effectively improving the separation effect and separation efficiency. 2. The partition reflux holes are evenly distributed around the partition feed hole to ensure that the guide tube is evenly stressed, thereby ensuring the stability of the guide tube. 3. The setting of the reinforcement ring effectively ensures the strength and stability of the molten sulfur kettle cylinder.
