Description

Technical Field

[0001] This utility model relates to the field of sulfur vapor preparation, and more particularly to the technical field of a sulfur vapor preparation device. Background Technology

[0002] Sulfur vapor is a crucial raw material for the growth of artificial crystals using chemical vapor deposition (CVD). Currently, the commonly used method involves heating sulfur to 444.6°C in a crucible until it boils and produces sulfur vapor. High-purity helium is then injected into the crucible to agitate the liquid sulfur, causing it to boil further and generate more sulfur vapor. This vapor is then carried into the artificial crystal reactor by the helium. Due to the high density and boiling point of liquid sulfur (444.6°C), sulfur evaporation is extremely slow, resulting in a very small amount of sulfur vapor produced per unit time. This leads to a very slow artificial crystal growth rate, approximately 20 days, with a growth yield of only about 20 kg, severely limiting the manufacturing efficiency of artificial crystals. Furthermore, the traditional method of introducing sulfur vapor into the reactor using an inert gas results in a low sulfur vapor concentration, which affects the reaction rate and further reduces production efficiency. Since sulfur has a flash point of approximately 250°C, the excessively high temperature during sulfur vapor preparation poses significant safety risks during production.

[0003] Therefore, how to achieve efficient low-temperature preparation of pure sulfur vapor remains a challenging problem to be solved in this field. Utility Model Content

[0004] To address the aforementioned technical issues, a sulfur vapor preparation apparatus is provided to achieve efficient and low-temperature preparation of pure sulfur vapor.

[0005] According to the present invention, a sulfur vapor preparation device is provided, including a sulfur melting device, a secondary sulfur heating device, a sulfur melt atomization device, and a sulfur vapor separation device;

[0006] The sulfur melting device includes a sulfur melting tank and a first heating device connected to the sulfur melting tank.

[0007] The secondary sulfur heating device includes a sulfur melt storage device and a second heating device connected to the sulfur melt storage device.

[0008] The sulfur melting tank is connected to the sulfur melt storage device;

[0009] The outlet of the sulfur melt storage device is connected to the sulfur melt atomizing device;

[0010] The sulfur vapor separation device includes a liquid inlet, a liquid outlet, and a gas outlet.

[0011] The outlet of the sulfur melt atomizing device is connected to the inlet of the separation device, and the outlet of the separation device is connected to the sulfur melt storage device.

[0012] The outlet of the separation device is connected to the sulfur vapor utilization device via a regulating valve.

[0013] Compared with the prior art, the advantages of this utility model are as follows: by using the sulfur melting device, which includes a sulfur melting tank and a first heating device connected to the sulfur melting tank, elemental sulfur is placed in a sulfur storage tank for the first heating to obtain a primary sulfur melt, thereby achieving the melting of elemental sulfur without the need to control the temperature uniformity and flowability of the sulfur melt.

[0014] The secondary sulfur heating device includes a sulfur melt storage device and a second heating device connected to the sulfur melt storage device. The primary sulfur melt is heated a second time to obtain a secondary sulfur melt. The internal temperature of the secondary sulfur melt is uniform and stable, which is beneficial to the good flowability of the secondary sulfur melt. This is beneficial to the stable flow rate when the secondary sulfur melt is accurately metered and transported by the pump. At the same time, it is beneficial to the good atomization effect when the sulfur melt is atomized by the subsequent sulfur melt atomizing device.

[0015] The outlet of the sulfur melt atomizing device is connected to the inlet of the separation device, and the outlet of the separation device is connected to the sulfur melt storage device. This allows for the partial vaporization of the sulfur melt in the sulfur melt storage device into sulfur vapor in the sulfur vapor separation device, while the remaining atomized sulfur melt is deposited as deposited sulfur melt, thus enabling the preparation of sulfur vapor at a lower temperature. It also allows for the recycling of the deposited sulfur melt, resulting in low costs for industrial production. Furthermore, it facilitates the control of sulfur vapor pressure in the vaporization container by adjusting the flow rate of the recycled deposited sulfur melt without needing to adjust the flow rate of the secondary sulfur melt entering the vaporization container.

[0016] The outlet of the separation device is connected to the sulfur vapor utilization device via a regulating valve. When the sulfur vapor separation device reaches the preset pressure range, the exhaust port on the top surface of the sulfur vapor separation device is opened to connect the sulfur vapor separation device with the sulfur vapor utilization container. This helps to stabilize the obtained sulfur vapor pressure, thereby facilitating a stable flow rate of sulfur vapor supplied to the sulfur vapor utilization device, and eliminating the need for mixing inert gas with sulfur vapor during transportation.

[0017] Furthermore, the first heating device is a first electric heating device or a first liquid heat source heating device;

[0018] The first liquid heat source heating device includes a first heating pipe; the first heating pipe is wound and connected to the sulfur melting tank, and the first heating pipe is spirally arranged;

[0019] The first heating pipe is connected to the first heat source storage container via a circulation pump; the first heating pipe is filled with a first heat source solution, the temperature of which is 118-122℃.

[0020] The beneficial effect of the previous step is that by using the first heat source solution at a temperature of 118-122℃, both the melting of elemental sulfur and the temperature of the primary melt are lower than the ignition point of sulfur; this is conducive to improving work efficiency and achieving high sulfur melt production efficiency.

[0021] Furthermore, the second heating device is a second electric heating device or a second liquid heat source heating device;

[0022] The second liquid heat source heating device includes a second heating pipe; the second heating pipe is wound and connected to the sulfur melt storage device, and the second heating pipe is spirally arranged;

[0023] The second heating pipe is connected to the second heat source storage container via a circulation pump; the second heating pipe is filled with a second heat source solution, the temperature of which is 133-138℃.

[0024] The advantages of the previous step are that by using a second heat source solution with a temperature of 133-138℃, the temperature of the secondary sulfur melt is made uniform, which is conducive to the good flowability of the secondary sulfur melt. This is conducive to the stable flow rate when the secondary sulfur melt is metered and transported by the pump, and also to the good atomization effect when it is atomized by the atomizing device. The temperature of the secondary sulfur melt is lower than the ignition point of sulfur. The safety hazards are extremely low and it is conducive to improving work efficiency and achieving high sulfur melt production efficiency.

[0025] Furthermore, the second heating device includes a first heating mechanism, a second heating mechanism, and a heating and heat preservation mechanism;

[0026] The first heating mechanism includes a first infusion pipe and a third heating pipe sleeved outside the first infusion pipe; the first infusion pipe is spirally arranged.

[0027] The second heating mechanism includes a second infusion pipe and a fourth heating pipe sleeved outside the second infusion pipe; the second infusion pipe is spirally arranged.

[0028] The heating and insulation mechanism includes a fifth heating pipe wound and connected to the sulfur melt storage device or a fifth heat source heating layer sleeved on the outside of the sulfur melt storage device.

[0029] One end of the first infusion pipeline is connected to the sulfur melting device, and the other end of the first infusion pipeline is connected to the second infusion pipeline;

[0030] The second liquid delivery pipeline is connected to the sulfur melt storage device;

[0031] The third heating pipe is connected to the third heat source storage container via a circulation pump, the fourth heating pipe is connected to the fourth heat source storage container via a circulation pump, and the fifth heating pipe or the fifth heat source heating layer is connected to the fifth heat source storage container via a circulation pump.

[0032] Furthermore, the third heating pipe is circulated with a third heat source solution, the temperature of which is 125-128°C;

[0033] The fourth heating pipe is filled with a fourth heat source solution, the temperature of which is 133-138℃.

[0034] The fifth heating pipe is filled with a fifth heat source solution, and the temperature of the fifth heat source solution is 135-136℃.

[0035] Preferably, the inner diameter of the first infusion tube is 3-10 cm, or the inner diameter of the second infusion tube is 5-10 cm; the length of the second infusion tube is greater than the length of the first infusion tube; more preferably, the inner diameter of the second infusion tube is greater than the inner diameter of the first infusion tube.

[0036] The beneficial effect of the previous step is that, by using the first heating mechanism, which includes a first liquid delivery pipe and a third heating pipe sleeved outside the first liquid delivery pipe, and the first liquid delivery pipe being spirally arranged, and the second heating mechanism, which includes a second liquid delivery pipe and a fourth heating pipe sleeved outside the second liquid delivery pipe, and the second liquid delivery pipe being spirally arranged, heating can be carried out simultaneously during the transportation of the primary sulfur melt, improving work efficiency, saving process time, and ensuring uniform heating of the primary sulfur melt; at the same time, the spiral arrangement of the first liquid delivery pipe further facilitates uniform heating of the primary sulfur melt during transportation in the first liquid delivery pipe;

[0037] The heating and insulation mechanism includes a fifth heating pipe that is wound and connected to the sulfur melt storage device, which further achieves uniform temperature of the secondary sulfur melt and facilitates the stable supply of the secondary sulfur melt to the sulfur melt atomization device.

[0038] By using the third heat source solution at a temperature of 125-128℃ and the fourth heat source solution at a temperature of 133-138℃, the sulfur melt is heated in stages, improving the heating efficiency and resulting in a uniform temperature of the secondary sulfur melt.

[0039] The first infusion pipe has an inner diameter of 3-10cm and the second infusion pipe has an inner diameter of 5-10cm, which can not only meet the sulfur melt transportation efficiency, but also further promote the uniform heating of the primary sulfur melt in the first infusion pipe.

[0040] With further optimization, the inner diameter of the second infusion pipe is larger than that of the first infusion pipe, which is beneficial for dispersing the primary sulfur melt when it enters the second infusion pipe through the first infusion pipe. This further facilitates the uniform heating of the primary sulfur melt in the second infusion pipe. The length of the second infusion pipe is greater than that of the first infusion pipe, which satisfies the requirement that the two-stage heating time is 3-5 minutes.

[0041] Furthermore, the liquid outlet of the separation device is located on the bottom surface of the sulfur vapor separation device, and the liquid outlet of the separation device is connected to the sulfur melt storage device through a pipeline and a frequency converter pump.

[0042] The sulfur molten liquid deposited in the sulfur vapor separation unit is transported to the sulfur molten liquid storage unit by a variable frequency pump.

[0043] The gas outlet of the separation device is located on the top surface of the sulfur vapor separation device;

[0044] The liquid inlet of the separation device is located on the side wall of the sulfur vapor separation device, away from the gas outlet of the separation device.

[0045] The beneficial effect of the previous step is that the variable frequency pump can be used to transport the deposited sulfur melt in the sulfur vapor separation device to the sulfur melt storage device through the liquid outlet of the gasification container; at the same time, the variable frequency pump can be used to regulate the flow rate of the deposited sulfur melt, thereby controlling the return flow rate of the deposited sulfur melt and stabilizing the sulfur vapor pressure in the gasification container.

[0046] The fact that the liquid inlet of the separation device is located on the side wall of the sulfur vapor separation device, away from the gas outlet of the separation device, helps to prevent some unvaporized sulfur melt from entering the sulfur vapor utilization device.

[0047] Furthermore, a third heating device is provided at the bottom of the sulfur vapor separation device to control the temperature of the deposited sulfur melt in the sulfur vapor separation device to 133-138℃;

[0048] and / or

[0049] The sulfur melt atomizing device includes an atomizing nozzle; or, the sulfur melt atomizing device includes an inlet channel, a first container, a liquid separating device, and a sixth heating pipe sleeved outside the first container, wherein the temperature of the sixth liquid heat source inside the sixth heating pipe is 135-136℃; the liquid separating device is sleeved inside the first container and is connected to the inlet channel, the liquid separating device includes a liquid separating device shell with several liquid outlet holes on the side wall and bottom, and a liquid separating wheel rotatably connected to the liquid separating device shell; the first container and the outer wall of the liquid separating device form a liquid outlet cavity, the bottom surface of the first container is provided with several atomizing liquid outlet holes, several atomizing liquid outlet pipes are provided between the bottom surface of the first container and the liquid separating device, the liquid outlet of the atomizing liquid outlet pipe is connected to the bottom surface of the first container, the end of the atomizing liquid outlet pipe away from the bottom surface of the first container is sealed, the side wall of the atomizing liquid outlet pipe is provided with several pipe inlet holes, the liquid outlets of the pipe inlet holes are symmetrically arranged on the side wall of the liquid outlet pipe; the liquid outlet of the atomizing liquid outlet pipe is connected to the inlet of the separation device.

[0050] The advantage of the previous step is that by controlling the temperature of the deposited sulfur melt in the sulfur vapor separator to 133-138°C, it is beneficial to stabilize the sulfur vapor pressure in the sulfur vapor separator.

[0051] The sulfur melt atomization device includes an inlet channel, a first container, a liquid distribution device, and a sixth heating pipe fitted outside the first container. The temperature of the sixth liquid heat source in the sixth heating pipe is 135-136℃, which achieves high sulfur melt atomization efficiency and avoids a significant drop in melt temperature during atomization, while also ensuring a stable flow rate of atomized sulfur melt.

[0052] Furthermore, the sulfur vapor separation device also includes an isolation plate, which is connected to the bottom surface of the sulfur vapor separation device; the isolation plate is provided with several ventilation holes;

[0053] The end of the isolation plate that is away from the bottom surface of the sulfur vapor separator is at a certain distance from the top surface of the sulfur vapor separator.

[0054] The liquid inlet and air outlet of the separation device are located on both sides of the isolation plate.

[0055] The advantage of the previous step is that the isolation plate is connected to the bottom surface of the sulfur vapor separation device; the isolation plate is provided with several vent holes; this further helps to prevent some unvaporized sulfur melt from entering the sulfur vapor utilization device.

[0056] Furthermore, the isolation plate is set perpendicular to the bottom surface of the sulfur vapor separation device, and the side wall of the sulfur vapor separation device where the liquid inlet of the separation device is located is set parallel to the isolation plate, with a distance of ≥35cm between the side wall of the sulfur vapor separation device and the isolation plate.

[0057] The advantage of adopting the previous step is that it helps to prevent some unvaporized molten sulfur from entering the sulfur vapor application device, and also helps to avoid the problem of reduced atomization efficiency caused by the atomized molten sulfur being directly sprayed onto the surface of the isolation plate.

[0058] Furthermore, the sulfur vapor preparation device also includes a PLC control system; a pressure sensor is installed below the gas outlet of the separation device; the pressure sensor is electrically connected to the PLC control system.

[0059] The pressure sensor and the variable frequency pump connected to the liquid outlet of the separation device via a pipeline are interlocked by a PLC control system.

[0060] The advantage of the previous step is that it enables automatic and high-precision control of the sulfur vapor pressure in the sulfur melt atomization device, thereby stabilizing the flow rate of sulfur vapor entering the sulfur vapor utilization device. Attached Figure Description
