Description

Technical Field

[0001] This utility model belongs to the field of sulfur storage technology, specifically relating to a coil-type liquid sulfur heating device. Background Technology

[0002] Sulfur is a light yellow crystal with the molecular formula S and a molecular weight of 32.06. It is insoluble in water but readily soluble in carbon disulfide. Its melting point is 112–119°C, boiling point is 444.6°C, and autoignition point is 248–266°C. Liquid sulfur in air can burn upon contact with an open flame at 150°C. Its density is 1.92–2.07.

[0003] Liquid sulfur has unique viscosity-temperature properties. It has low viscosity and good fluidity at 130-160℃. At 160-190℃, the viscosity increases due to the breaking of the S8 ring dry chain. Above 190℃, the average chain length shortens and the viscosity decreases again.

[0004] The core advantage of a steam system consisting of steam coils and a steam generator over electric heating lies in its superior economy and versatility. It utilizes low-cost fuels (such as natural gas and coal) to produce high-temperature steam, and through centralized heating, it can meet the enormous heat energy demands of large-scale industrial production at extremely low operating costs. Simultaneously, the steam releases latent heat through condensation and phase change, providing a stable, uniform, and high-quality heat source, making it ideal for applications with stringent process requirements. Furthermore, it features sterility and explosion-proof safety (no electric sparks), effectively addressing multiple needs such as heating, sterilization, and power generation, making it an irreplaceable high-efficiency energy system in the industrial sector.

[0005] Based on the aforementioned objective facts, liquid sulfur heating devices using steam coils as heating elements have emerged, such as CN201921759767.7, a dedicated liquid sulfur storage tank. However, the applicant's research and analysis revealed certain defects in existing coil-type liquid sulfur heating devices. Specifically, coil heating relies on the temperature difference between the steam inside the pipe and the substance to be heated. The greater the temperature difference, the faster the substance heats up, resulting in a higher final temperature. In the initial stage of heat exchange, the temperature difference between the steam and sulfur at the front end of the coil is large, causing the sulfur to rapidly heat up and melt into a liquid state. However, as heat exchange continues, the temperature difference between the steam and sulfur at the rear end of the coil decreases, causing the sulfur at the rear of the coil to require a longer time to melt, thus increasing the overall heating time. Increasing the steam temperature at the front end of the coil can shorten the overall heating time, but it also presents the problem of excessively high liquid sulfur temperature at the front end of the coil, leading to reduced fluidity. Utility Model Content

[0008] Furthermore, the container is also equipped with a stirring paddle, the blades of which are disposed on the sides and in the gaps of each coil, and the stirring rod of the stirring paddle extends outside the container and is connected to the motor output shaft via a coupling.

[0009] Furthermore, the motor is equipped with a power supply and a controller.

[0010] Furthermore, the input and output ports of the coil are respectively connected to the high-temperature steam output pipe of the steam generator and the condensate recovery pipe of the steam generator.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] A coil-type liquid sulfur heating device is provided, wherein multiple sets of spiral coils 2 are installed at intervals inside the insulated container 1. The installation direction of each coil 2 is uniform. The input and output ports of each coil 2 extend to the outside of the container 1 and are respectively connected to the high-temperature medium output pipe and the low-temperature medium recovery pipe. The insulated container 1 is also equipped with an input pipe 3 and an output pipe 4 for material entry and exit.

[0021] In a preferred embodiment, the container 1 is further equipped with a stirring paddle 5. The blades of the stirring paddle 5 are disposed on the sides and in the gaps of each coil 2. The stirring rod of the stirring paddle 5 extends outside the container 1 and is connected to the output shaft of the motor 6 via a coupling.

[0022] In a preferred embodiment, the motor 6 is equipped with a power supply and a controller.

[0023] In a preferred embodiment, the input and output ports of the coil 2 are respectively connected to the high-temperature steam output pipe of the steam generator and the condensate recovery pipe of the steam generator.

[0024] In a preferred embodiment, the input port of the coil 2 is located at a high position, and the output port is located at a low position.

[0025] In a preferred embodiment, the input pipe 3 and the output pipe 4 are equipped with valves.

[0026] In a preferred embodiment, the insulated container 1 is equipped with a pressure gauge and a safety valve.

[0027] Specifically, the installation gaps between the insulated container 1, the coil 2, and the agitator 5 are sealed.

[0028] The working principle of this embodiment will be further described below with reference to the content described in the embodiments:

[0029] Combined with appendix Figure 1 It can be seen that the rotation direction of each coil 2 in the insulation container 1 is the same, and the installation positions of the inlet and outlet pipes are also the same. The rear section of the front coil 2 is adjacent to the front section of the rear coil 2.

[0030] Thus, when the sulfur to be heated and melted enters the insulation container 1 through the input pipe 3, the valve of the input pipe 3 is closed, and the valves of the pipes connecting the steam generator to each coil 2 are opened. High-temperature steam enters each coil 2 through the input port and then discharges low-temperature steam and condensate through the output port. Each coil 2 is only responsible for heating a small area, so that the sulfur in the insulation container 1 is heated evenly.

[0031] In addition, the stirring paddle 5, driven by the motor 6, is installed inside the insulated container 1 to stir the sulfur inside the container 1, further ensuring uniform heating of the sulfur.

[0032] After the sulfur melts, open the output pipe 4 and the liquid sulfur flows out. After the process is complete, close the valves on the pipes connecting the steam generator to each coil 2.
