Description

Technical Field

[0001] This invention belongs to the field of sulfur melting kettle technology, specifically a high-efficiency sulfur melting kettle. Background Technology

[0002] Sulfur foam generated during wet desulfurization of sulfur-containing gases in fertilizer plants and coking plants is typically collected and stored in sulfur foam tanks. A sulfur melting reactor is the equipment used to process this sulfur foam. In sulfur foam, sulfur exists as tiny elemental sulfur particles attached to the foam. During operation, compressed air or an alkali-resistant pump is used to transport the sulfur foam into the melting reactor. The melting reactor is a jacketed container; steam is circulated within the jacket to heat the sulfur foam. When heated to 70-90°C, the foam ruptures, and the tiny elemental sulfur particles rapidly aggregate and increase in size, separating from the desulfurization liquid. A desulfurization liquid (clear liquid) collector is installed at the top of the melting reactor, facilitating the entry and collection of desulfurization liquid while preventing the entry of sulfur particles. The collected desulfurization liquid is discharged from the melting reactor and recycled back into the desulfurization system for reuse. The remaining sulfur particles sink to the bottom of the sulfur melting kettle by their own weight. A sulfur melting heater is installed at the bottom of the kettle. The sinking particles accumulate and are continuously heated. When heated to 120-130℃, they become molten sulfur that is easy to flow. This molten sulfur is discharged from the kettle and, after cooling, becomes solid sulfur in lumps for recycling. In some current sulfur melting kettles, the sulfur foam can only come into contact with the heat of the first jacket, resulting in uneven heating and low efficiency. Moreover, the sulfur particles that fall to the bottom of the kettle through the heating pipes can only melt slowly, which not only results in uneven heating but also low efficiency and can easily lead to situations where some parts are too hot and some parts are too cold. Summary of the Invention

[0003] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is to provide a high-efficiency sulfur melting kettle to solve the problem of uneven heating of sulfur foam and sulfur particles in the current sulfur melting kettle and low conversion efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A high-efficiency sulfur melting kettle includes a kettle body, a first jacket, a second jacket, an inner cylinder, and a stirring device. The first jacket and the second jacket are arranged on the outer side of the kettle body and are not connected. An inner cylinder is arranged on the upper side of the kettle body, and the lower end of the inner cylinder is connected to the inner wall of the kettle body through an annular plate. A first cavity is arranged inside the side wall of the inner cylinder, and the first cavity is connected to the first jacket through a first connecting rod. A first bottom plate and a second bottom plate are respectively arranged on the lower end of the kettle body. A stirring device is arranged inside the kettle body, and the position of the stirring device corresponds to the position of the first bottom plate and the second bottom plate. The upper end of the stirring device is connected to the second connecting rod through a bearing. The second connecting rod is connected to the second jacket. A feed inlet is arranged at the upper end of the kettle body, and a discharge outlet is arranged at the lower end of the kettle body.

[0006] Furthermore, the upper end of the inner cylinder is provided with an air outlet, and the outer end of the air outlet is located on the outside of the vessel body.

[0008] Furthermore, the ring plate is fixedly connected to both the vessel body and the inner cylinder, and the ring plate is provided with through holes.

[0009] Furthermore, the stirring device includes a motor, a transmission gear, a transmission shaft, and a stirring rod. The motor is connected to the transmission shaft via the transmission gear.

[0010] Furthermore, both the drive shaft and the stirring rod have cavities inside, and the second jacket is connected to the internal space of the drive shaft and the stirring rod.

[0013] Furthermore, the shape of the stirring rod corresponds to the shape of the first base plate and the second base plate.

[0014] Beneficial effects: Compared with the prior art, this application has the following advantages:

[0015] 1. The high-efficiency sulfur melting kettle is equipped with a first cavity on the inner cylinder. The first cavity is connected to the first jacket. When steam enters the first jacket, steam will also enter the interior of the first cavity. When sulfur foam enters, it will be heated in all directions, ensuring that the sulfur foam is heated evenly and improving working efficiency. Moreover, the high-temperature gas generated by the melting of sulfur particles will be discharged through the inner cylinder, which can also heat the first cavity and improve the utilization efficiency of steam.

[0016] 2. This high-efficiency sulfur melting kettle is equipped with a bottom plate and a stirring device. Sulfur particles fall onto the first bottom plate and the second bottom plate. The stirring device stirs the sulfur particles on the first bottom plate and the second bottom plate. When steam enters the second jacket, it also enters the first bottom plate, the second bottom plate and the stirring device. The stirring device can heat the sulfur particles while rotating and stirring, making the sulfur particles heat more evenly and faster. Moreover, the first bottom plate and the second bottom plate can also play an auxiliary heating role.

[0017] 3. The internal structure of this high-efficiency sulfur melting kettle is meticulously designed and ingeniously integrated. It not only maximizes the utilization of steam, but also ensures that the sulfur foam is heated more evenly during the conversion process, resulting in faster working efficiency and further improving sulfur melting technology.

[0019] Figure 2 This is a schematic diagram of the structure of a high-efficiency sulfur melting kettle. Detailed Implementation

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2As shown, the high-efficiency sulfur melting kettle includes a kettle body 1, a first jacket 2, a second jacket 3, an inner cylinder 6, and a stirring device. The first jacket 2 and the second jacket 3 are located on the outer side of the kettle body 1, with the first jacket 2 on top and the second jacket 3 on the bottom. Air inlets a1 and a2 are respectively located on the upper sides of the first jacket 2 and the second jacket 3, and liquid outlets b1 and b2 are respectively located on the lower sides of the first jacket 2 and the second jacket 3. The first jacket 2 and the second jacket 3 are not connected to each other, ensuring more accurate temperature control within the two jackets and preventing mutual interference. The inner cylinder 6 is located on the upper side of the inside of the kettle body 1, and the lower end of the inner cylinder 6 is connected to the inner wall of the kettle body 1 via a ring plate 10. The area above the ring plate 10 is for sulfur melting. In the reaction site of the foam, sulfur foam is heated and converted into sulfur particles that fall from the ring plate 10. A first cavity 9 is provided inside the side wall of the inner cylinder 6. The first cavity 9 is connected to the first jacket 2 via a first connecting rod 8. When steam enters the first jacket 2, steam also enters the first cavity 9, forming a complete circulation space between the first jacket 2 and the first cavity 9. When sulfur foam enters, it is heated evenly, ensuring uniform heating and improving working efficiency. The high-temperature gas generated by the melting of the sulfur particles is discharged through the inner cylinder 6, which also heats the first cavity 9, improving the efficiency of steam utilization. A first bottom plate 11 and a first bottom plate 12 are respectively provided at the lower end of the inner part of the vessel body 1. The vessel body 1 has two bottom plates 12, and a stirring device is installed inside the vessel body 1. The position of the stirring device corresponds to the position of the first bottom plate 11 and the second bottom plate 12. The upper end of the stirring device is connected to the second connecting rod 17 via a bearing. The second connecting rod 17 is connected to the second jacket 3. The length of the inclined plate inside the first bottom plate 11 is shorter than that of the inclined plate inside the second bottom plate 12. Therefore, sulfur particles falling on the first bottom plate 11 will overflow from the top of the first inclined plate 111 to the second inclined plate 121 during the stirring process of the stirring device. The stirring rod of the stirring device will stir the sulfur particles on the first bottom plate 11 and the second bottom plate 12. Because the second jacket 3 and the first bottom plate 11 and the second bottom plate 12 are connected, the stirring device will stir the sulfur particles on the first bottom plate 11 and the second bottom plate 12. The stirring device forms a circulating space. When steam enters the second jacket 3, it also enters the first bottom plate 11, the second bottom plate 12, and the stirring device. The stirring device can heat the sulfur particles simultaneously during the rotation and stirring process, making the sulfur particles heat more evenly and faster. The first and second bottom plates can also play an auxiliary heating role. This device can make the sulfur foam heat more evenly during the conversion process, making the working efficiency faster and further improving the sulfur melting technology. The upper end of the vessel body 1 is provided with a feed port 4, and the lower end of the vessel body 1 is provided with a discharge port 5. The vessel body 1 is also equipped with the necessary pressure gauges, thermometers, etc., to ensure the safe operation of the device.

[0022] The upper end of the inner cylinder 6 is provided with an air outlet 7, and the outer end of the air outlet 7 is located outside the vessel body 1. The air outlet 7 is equipped with a safety valve and can stabilize the inner cylinder 6 to prevent it from shaking.

[0023] The upper end of the first cavity 9 is connected to the first connecting rod 8, which has an inner cavity. The first cavity 9 is connected to the first jacket 2 through the inner cavity. The lower end of the first cavity 9 is connected to the first jacket 2 through a connecting pipe. Steam enters each part of the first cavity 9 through the first jacket 2, forming a complete circulation space between the first jacket 2 and the first cavity 9. Steam enters from a1, and after absorbing heat, it condenses into liquid and flows out from b1. This steam circulation space can heat the sulfur foam from all sides, ensuring uniform heating of the sulfur foam and improving work efficiency.

[0024] The ring plate 10 is fixedly connected to the vessel body 1 and the inner cylinder 6 to ensure the connection strength between the ring plate 10 and the vessel body 1 and the inner cylinder 6, and to ensure the stability of the ring plate 10 and the inner cylinder 6. The ring plate 10 is provided with through holes, which can ensure that sulfur particles can pass through the through holes and fall down for the next reaction.

[0025] The stirring device includes a motor 13, a transmission gear 14, a transmission shaft 15, and a stirring rod 16. The motor 13 is connected to the transmission shaft 15 through the transmission gear 14. The motor 13 is fixed outside the vessel body 1. The rotation of the motor 13 drives the transmission shaft 15 to rotate through the transmission gear 14. The upper and lower ends of the transmission shaft 15 are connected to the second connecting rod 17 and the second jacket 3 respectively through bearings. The bearings ensure that the transmission shaft 15 can rotate normally. The stirring rod 16 is provided on the transmission shaft 15, and the transmission shaft 15 can drive the stirring rod 16 to rotate.

[0026] Both the drive shaft 15 and the stirring rod 16 have cavities inside. The second jacket 3 is connected to the internal space of the drive shaft 15 and the stirring rod 16. The second jacket 3 is connected to the drive shaft 15 and the stirring rod 16 to form a complete steam circulation space. Steam enters from a2 and finally condenses into liquid after absorbing heat and flows out from b2.

[0027] The first base plate 11 includes a first inclined plate 111 and a first flat plate 112. The first flat plate 112 is provided at the bottom end of the first inclined plate 111. The first flat plate 112 is connected to the second jacket 3. The first inclined plate 111 and the first flat plate 112 are provided with an inner cavity, which is connected to the second jacket 3. The first flat plate 112 is provided with a downstream outlet.

[0028] The second base plate 12 includes a second inclined plate 121 and a second flat plate 122. The second flat plate 122 is provided at the bottom end of the second inclined plate 121. The second flat plate 122 is connected to the second jacket 3. The second inclined plate 121 and the second flat plate 122 are provided with an inner cavity, which is connected to the second jacket 3. The second flat plate 122 is provided with a lower outlet. The top end of the second inclined plate 121 is connected to the transmission shaft 15 through a bearing.

[0029] like Figure 1As shown, when steam enters the second jacket 3, it also enters the first bottom plate 11 and the second bottom plate 12, ensuring that the sulfur particles in the upper part of the wheat are heated evenly. The first inclined plate 111 and the second inclined plate 121 are both frustum-shaped, but the top of the first inclined plate 111 is not closed, ensuring that the sulfur particles can overflow from the top of the first inclined plate 111 and fall onto the second inclined plate 121. The sulfur particles melt when heated and flow from the lower outlet of the first plate 112 to the second bottom plate 12, and then through the lower outlet of the second bottom plate 122, and finally out of the discharge port 5.

[0030] The shape of the stirring rod 16 corresponds to the shape of the first base plate 11 and the second base plate 12, ensuring that the stirring rod 16 can evenly stir the sulfur particles on the first base plate 11 and the second base plate 12, and also make the sulfur particles heat more evenly.

[0031] This invention provides a concept and implementation method for a high-efficiency sulfur melting kettle, which has many specific applications. The above is only a preferred embodiment of this invention. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of this invention, and these improvements should also be considered within the scope of protection of this invention.
