Description

Technical Field

[0001] This utility model relates to the field of sulfur melting pool technology, specifically a sulfur melting pool based on steam heating. Background Technology

[0002] The sulfur melting pool is a key piece of equipment in chemical, environmental protection, and sulfur recovery systems used to melt solid sulfur into a liquid state and separate impurities. Its core function is to achieve efficient phase change and purification of sulfur, providing qualified molten sulfur raw materials for subsequent sulfur storage, transportation, or processing. Currently, sulfur melting pools are usually heated by steam. High-temperature steam is passed through evenly distributed steam coils inside the pool to heat the sulfur. However, during operation, since the heating height of the steam coils is fixed, the sulfur level in the melting pool will change as the sulfur melts and is fed in and out. When the level is low, some of the steam coils will be above the sulfur level, resulting in ineffective heat transfer to the sulfur and significant energy waste. Utility Model Content

[0003] The purpose of this invention is to provide a sulfur melting pool based on steam heating, which has the advantage of allowing personnel to easily adjust the height of the steam heating according to the sulfur level, thus avoiding energy waste caused by the steam heating height being above the sulfur level.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] The components of this application, including the sulfur melting pool body 1, gas guide pipe 2, fixed box 3, push rod 4, adjusting screw 5, fixed cross plate 6, guide slide rod 7, moving frame 8, rubber sealing ring 9, guide plate 10, support frame 11, stainless steel steam coil 12, return spring 13, ultrasonic liquid level sensor 14, stepper motor 15, support plate 16, rubber sealing gasket 17, sealing baffle 18, fixed cylinder 19, guide hole 20, and guide rod 21, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0021] Example 1:

[0022] Please see Figures 1-4 As shown, this utility model provides a sulfur melting pool based on steam heating, including a sulfur melting pool body 1. Fixed boxes 3 are fixedly connected to both ends of the right side of the sulfur melting pool body 1. A gas guide pipe 2 is fixedly connected to the side of the two fixed boxes 3 that is far apart from each other. A stainless steel steam coil 12 is fixedly installed between the left sides of the two fixed boxes 3. A fixed cylinder 19 is fixedly connected to the right side of the fixed box 3. A push rod 4 is movably connected to the middle end of the fixed cylinder 19. A sealing baffle 18 is fixedly connected to the left side of the push rod 4. A return spring 13 is fixedly connected between the right side of the sealing baffle 18 and the right side of the inner cavity of the fixed cylinder 19. A fixed horizontal plate 6 is fixedly connected between the lower ends of the two fixed boxes 3. A stepper motor 15 is fixedly installed at the middle end of the bottom of the fixed horizontal plate 6. An adjusting screw 5 is fixedly installed at the output end of the stepper motor 15. A movable frame 8 is threadedly connected to the upper end of the adjusting screw 5. Guide plates 10 are fixedly connected to both sides of the movable frame 8.

[0023] In this technical solution, two sets of air guide pipes 2 are connected to the steam conveying pipe and the steam discharge pipe, respectively. This allows the high-temperature steam to be diverted through the air guide pipes 2 and the fixed box 3 to multiple sets of stainless steel steam coils 12 during transport, while simultaneously being discharged through another fixed box 3 and the air guide pipe 2 to the steam discharge pipe. Furthermore, as the high-temperature steam flows through the stainless steel steam coils 12, its heat is rapidly transferred to the sulfur within the sulfur melting pool body 1, causing the sulfur to melt under heat. When the sulfur level inside the sulfur melting pool body 1 falls below a certain threshold... When adjusting the height of the stainless steel steam coil 12, an external PLC controller starts the stepper motor 15 according to the preset number of rotations, which drives the adjusting screw 5 to rotate. The rotation of the adjusting screw 5 drives the moving frame 8 and the guide plate 10 to move downward, so that the guide plate 10 can contact the surface of the push rod 4 and push the push rod 4 and the sealing baffle 18 to the left along the inclined plane. Under the action of movement, the sealing baffle 18 can block the openings on both sides of the stainless steel steam coil 12, thereby preventing steam from entering the stainless steel steam coil 12 which is higher than the sulfur liquid level and causing energy waste.

[0024] It should be noted that, firstly, the high-temperature steam originates from the waste heat steam generator of the sulfur incinerator exhaust gas and can be continuously transported by a high-pressure steam screw pump; secondly, during the movement of the guide plate 10 and the pushing rod 4 and the sealing baffle 18, while the sealing baffle 18 can seal the opening of the stainless steel steam coil 12, the vertical surface of the guide plate 10 will contact the right end of the pushing rod 4 under the action of movement. Then, during the movement of the guide plate 10, the corresponding pushing rod 4 and the sealing baffle 18 can be pushed from top to bottom in sequence, and the corresponding stainless steel steam coil 12 will be sealed.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, an ultrasonic level sensor 14 is fixedly installed at the right end of the top of the sulfur melting pool body 1. A support frame 11 is fixedly connected to the left side of the inner cavity of the sulfur melting pool body 1. The right end of the support frame 11 is fixedly installed at the left end of the stainless steel steam coil 12. The top of the adjusting screw 5 is movably connected to the support plate 16 through a bearing. The left side of the support plate 16 is fixedly connected to the upper right end of the outer surface of the sulfur melting pool body 1. A guide slide rod 7 is fixedly connected between the top of the fixed horizontal plate 6 and the upper right end of the outer surface of the sulfur melting pool body 1. The surface of the moving frame 8 is movably connected to the surface of the guide slide rod 7. A rubber sealing ring 9 is fixedly installed at the right end of the fixed cylinder 19. The surface of the push rod 4 contacts the surface of the rubber sealing ring 9. A rubber sealing gasket 17 is fixedly installed on the left side of the sealing baffle 18. Guide holes 20 are opened at both ends of the left side of the fixed cylinder 19. A guide rod 21 is movably connected to the surface of the guide hole 20. The left side of the guide rod 21 is fixedly connected to the right side of the sealing baffle 18.

[0027] In this technical solution, the ultrasonic level sensor 14 is used to monitor the sulfur level inside the sulfur melting pool 1, allowing back-end personnel to understand the sulfur level height. The support frame 11 is used to support the left end of the stainless steel steam coil 12. The support plate 16 is used to support the top of the adjusting screw 5, preventing the adjusting screw 5 from tilting due to force. The guide slide rod 7 is used to guide the moving frame 8, preventing the moving frame 8 from tilting or shifting during movement. The rubber sealing ring 9 and rubber sealing gasket 17 are used to effectively improve the sealing performance between the push rod 4 and the fixed cylinder 19, and between the sealing baffle 18 and the stainless steel steam coil 12. The guide hole 20 and guide rod 21 are used to guide the sealing baffle 18.

[0028] It should be noted that, firstly, both the rubber sealing ring 9 and the rubber sealing gasket 17 are made of fluororubber, which has good high-temperature resistance and ensures the service life of the rubber sealing ring 9 and the rubber sealing gasket 17; secondly, the ultrasonic liquid level sensor 14, as existing technology, can realize liquid level detection through non-contact measurement principle (time difference method).

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
