Description

Technical Field

[0001] The utility model relates to the technical field of sulfur hexafluoride production, and more specifically to a sulfur hexafluoride reactor. Background Art

[0002] Sulfur hexafluoride has excellent electrical insulation and arc extinguishing properties. Under the same conditions, its insulation capacity is more than 2.5 times that of air and nitrogen, and its arc extinguishing capacity is 100 times that of air. The melting point of sulfur hexafluoride is -50.8℃, and it can be used as a special refrigerant in the temperature range of -45 to 0℃. Because of its good heat resistance, it is a stable high-temperature heat carrier. Due to the above and other excellent properties, sulfur hexafluoride has been widely used in the power, electronics, electrical industry, laser, medical, meteorological, refrigeration, fire protection, chemical, military, aerospace, non-ferrous metallurgy, physical research, etc. in recent years. Sulfur hexafluoride (SF6) is a colorless, tasteless, odorless, non-toxic non-combustible gas under normal conditions. The molecular weight is 146.06 and the density is 6.139g / l, which is about 5 times that of air. It is one of the best known chemically stable substances, and its inertness is similar to that of nitrogen. It has excellent thermal stability and does not decompose even above 500℃ in its pure state.

[0003] Sulfur hexafluoride is often produced by the direct reaction of fluorine gas and sulfur. There are three specific methods: gas-solid reaction: fluorine gas directly contacts and reacts with solid sulfur; gas-liquid reaction: fluorine gas reacts with molten sulfur; gas-gas reaction: fluorine gas reacts with gaseous sulfur. The reaction of fluorine gas with gaseous sulfur is to heat sulfur to above 445°C (boiling point). This method has the defect that the reaction temperature is difficult to control. At the same time, the reactor must be made of special materials, which is not suitable for industrial production. Sulfur is converted into gas and sent into the reactor to react with fluorine. Since the fluorine-sulfur reaction is a violent exothermic reaction, the temperature is difficult to control when fluorine gas and sulfur react, and the reaction efficiency is low. At the same time, the reactor must be made of special materials, which is not suitable for industrial production. The reaction of fluorine gas with molten sulfur is to keep the sulfur in the reactor in a molten state to react with the introduced fluorine gas. It is the main method for the industrial production of sulfur hexafluoride at present, but the temperature is difficult to control when fluorine gas and sulfur react, and there is a problem of low reaction efficiency.

[0004] Therefore, how to solve the problem of low reaction efficiency of fluorine gas and sulfur is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0025] The sulfur hexafluoride reactor provided by the utility model comprises a reactor body. Specifically, the reactor body is a horizontal structure. A sulfur inlet, a fluorine gas inlet and a gas outlet are arranged on the top of the reactor body. Fluorine gas and sulfur are added into the reactor body through the sulfur inlet and the fluorine gas inlet. The sulfur is added to a preset position.

[0026] The fluorine gas inlet is arranged near the first end of the reactor body, the gas outlet is arranged near the second end of the reactor body, and the sulfur inlet is located between the fluorine gas inlet and the gas outlet.

The air-guiding structure is provided to effectively control the flow rate and direction of the fluorine gas. A semicircular baffle is also provided in the reactor body between the gas outlet and the sulfur inlet.

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] It should be noted that the directional words such as "upper" and "lower" mentioned below are defined based on the drawings in the specification.

[0049] The core of the utility model is to provide a sulfur hexafluoride reactor, which effectively controls the progress of the fluorine-sulfur reaction and increases the reaction efficiency by controlling the flow rate and direction of the fluorine gas entering the reactor body 1.

[0050] Please refer to Figure 1 and Figure 2 A sulfur hexafluoride reactor includes a reactor body 1. Specifically, the reactor body 1 is a horizontal structure. A sulfur inlet 2, a fluorine gas inlet 3 and a gas outlet 4 are provided on the top of the reactor body 1. Fluorine gas and sulfur are added into the reactor body 1 through the sulfur inlet 2 and the fluorine gas inlet 3. The sulfur is added to a preset position. After the fluorine gas and sulfur react in the reactor body 1, the generated sulfur hexafluoride gas and the unreacted fluorine gas are discharged from the gas outlet 4.

[0051] The fluorine gas inlet 3 is arranged near the first end of the reactor body 1, the gas outlet 4 is arranged near the second end of the reactor body 1, and the sulfur inlet 2 is located between the fluorine gas inlet 3 and the gas outlet 4. Such an arrangement allows the fluorine gas and sulfur entering the reactor body 1 to react as fully as possible, and avoids too much fluorine gas being discharged from the gas outlet 4 before reacting with sulfur. A discharge port 5 is provided at the second end of the reactor body 1. During the long-term reaction process of fluorine gas and sulfur, slag will be formed on the liquid surface of sulfur. At this time, the slag on the sulfur liquid surface can be discharged through the discharge port 5 to avoid affecting the reaction of fluorine gas and sulfur due to the slag.

[0052] The reactor body 1 is provided with a cooling water cooling structure 6 and a heat preservation structure 7. The reaction process of fluorine gas and sulfur is an exothermic process. In order to prevent the high temperature generated by the reaction of fluorine gas and sulfur from causing the sulfur hexafluoride reactor to overheat, a cooling water cooling structure 6 is provided to improve the heat dissipation effect of the reactor body 1 and extend the life of the sulfur hexafluoride reactor. The heat preservation structure 7 is arranged circumferentially near the bottom of the reactor body 1. Sulfur will solidify below 140 degrees Celsius. When fluorine gas and sulfur have not reacted yet, in order to avoid sulfur solidification, a heat preservation structure 7 needs to be provided to keep the sulfur in a liquid state to ensure that the fluorine-sulfur reaction can proceed smoothly after the fluorine gas is introduced.

[0053] A gas-guiding structure 8 corresponding to the fluorine gas inlet 3 is provided in the reactor body 1 and extends radially along the reactor body 1. The gas-guiding structure 8 can be used to control the direction of the fluorine gas entering the reactor body 1. The gas inlet port of the gas-guiding structure 8 is larger than the fluorine gas inlet 3 so that the fluorine gas diffuses here after entering the reactor from the fluorine gas inlet 3, thereby slowing down the flow rate of the fluorine gas, which is more conducive to the control of the reaction. The gas-guiding structure 8 is provided to effectively control the flow rate and direction of the fluorine gas. A semicircular baffle 9 is also provided in the reactor body 1 between the gas outlet 4 and the sulfur inlet 2. By providing the semicircular baffle 9, the fluorine gas remaining from a single reaction can flow through the bottom of the semicircular baffle 9 and react again with the sulfur vapor under the semicircular baffle 9, thereby improving the overall reaction efficiency and reducing the amount of fluorine gas entrained at the gas outlet 4.

[0054] The sulfur hexafluoride reactor arranged in the above manner strengthens the control over the fluorine-sulfur reaction, improves the reaction efficiency, facilitates the slagging operation at the sulfur liquid surface, and reduces the amount of fluorine gas entrained at the gas outlet 4.

[0055] In the above embodiment, the gas guide structure 8 includes an end plate 81, a semicircular partition plate 82 and a baffle plate 83. The end plate 81 is arranged on one side of the fluorine gas inlet 3 along the axial direction of the reactor body 1. The end plate 81 is arranged close to the first end of the reactor body 1. The semicircular partition plate 82 is arranged on the other side of the fluorine gas inlet 3 along the axial direction of the reactor body 1. The end plate 81 is arranged away from the first end of the reactor body 1. The semicircular partition plate 82 extends to the axial position of the reactor body 1. A fluorine gas channel is formed between the semicircular partition plate 82 and the end plate 81. The axial distance of the fluorine gas channel along the reactor body 1 is greater than the axial distance of the fluorine gas inlet 3 along the reactor body 1. One end of the baffle plate 83 is connected to the end plate 81. The baffle plate 83 and the end face of the semicircular partition plate 82 are arranged at an angle of 15 degrees, and the bottom end of the baffle plate 83 is flush with the axis of the reactor body 1.

[0056] It should be noted that, by designing a semicircular partition 82 at the fluorine gas inlet 3, the fluorine gas diffuses here after entering the inner cavity of the reactor body 1 from the inlet, so that the flow rate of the fluorine gas is slowed down, which is more conducive to the control of the reaction. An inclined baffle 83 is designed on the lower end surface of the semicircular partition 82 to change the flow direction of the fluorine gas and increase the reaction efficiency. The length of the semicircular partition 82 is half the height of the reactor body 1 to ensure that the outlet height of the fluorine gas matches the height of the sulfur liquid level, to ensure that the fluorine gas coming out of the gas guide structure 8 reacts effectively with the sulfur vapor, and also facilitates the sulfur liquid surface slagging operation.

[0057] Among them, in this embodiment, the baffle 83 and the end surface of the semicircular partition 82 are set at an angle of 15 degrees, but in actual application, there is no limitation on the specific degree of the angle, as long as the above-mentioned technical effect can be achieved.

[0058] In the above case, a temperature measuring device 10 connected to the controller is provided at the top of the reactor body 1, and the temperature measuring device 10 extends to the inner cavity of the reactor body 1. The temperature measuring device 10 is set to one or more, and multiple temperature measuring devices 10 are arranged along the axial direction of the reactor body 1.

[0059] It can be understood that the reaction process between fluorine gas and sulfur is an exothermic process, which causes the temperature of the inner cavity of the reactor body 1 to rise. The temperature measuring device 10 is used to monitor the temperature of the inner cavity of the reactor body 1 in real time, and feed back the monitored data to the controller. The controller determines whether to pass cooling water into the cooling water cooling structure 6 based on the actual data. When the measured temperature is higher than the preset temperature, the controller controls the cooling water to pass cooling water into the cooling water cooling structure 6 to reduce the temperature of the inner cavity of the reactor body 1 to avoid damage to the reactor body 1 due to excessive temperature. Generally, the temperature of the upper inner cavity of the reactor body 1 is controlled within 250 degrees Celsius.

[0060] Among them, in this embodiment, the temperature measuring device 10 is arranged near the top of the reactor body 1, but in actual application, there is no limitation on the position, quantity, specification, etc. of the temperature measuring device 10, as long as the above-mentioned technical effect can be achieved.

[0061] Furthermore, the temperature measuring device 10 includes a thermometer sleeve 101 and a thermometer 102. The thermometer sleeve 101 is arranged through the cooling water cooling structure 6 and extends to the inner cavity of the reactor body 1. The outer periphery of the thermometer sleeve 101 is provided with a first connecting pipe connected to the reactor body 1. The first connecting pipe is arranged through the cooling water cooling structure 6, and a first flange is provided on the first connecting pipe. The thermometer 102 is arranged in the thermometer sleeve 101 and connected to the controller.

[0062] It should be noted that, in order to avoid corrosion to the thermometer 102, the thermometer 102 is set in the thermometer sleeve 101, and the thermometer sleeve 101 is fixed to the reactor body 1 through the first connecting pipe, bolts and other components. A flange is set on the first connecting pipe to realize the connection between the thermometer 102 and other components.

[0063] The first connecting pipe runs through the cooling water cooling structure 6 , and plays a supporting role for the cooling water cooling structure 6 .

[0064] In the above embodiment, the cooling water cooling structure 6 includes a first cooling component, a second cooling component and a third cooling component. The first cooling component is arranged in the semi-circumference near the top of the reactor body 1, and the second cooling component and the third cooling component are both arranged in the inner cavity of the reactor body 1. The second cooling component is arranged in the semi-inner cavity near the top of the reactor body 1, and the third cooling component is arranged in the semi-inner cavity near the bottom of the reactor body 1.

[0065] It can be understood that the first cooling component is arranged on the upper half of the reactor body 1, the second cooling component is arranged on the upper half of the inner cavity of the reactor body 1, and the third cooling component is arranged on the lower half of the inner cavity of the reactor body 1. The first cooling component, the second cooling component and the third cooling component are all connected to cooling water to achieve the effect of cooling the reactor body 1, avoiding damage to the reactor body 1 due to excessive heat generated by the fluorine-sulfur reaction, and shortening the service life of the reactor body 1.

[0066] Among them, in this embodiment, the first cooling component, the second cooling component and the third cooling component are arranged in this way, but in actual application, there is no restriction on the specific structure, arrangement method, quantity, etc. of the cooling water cooling structure 6, as long as the above-mentioned technical effect can be achieved.

[0067] Please refer to Figure 3 The first cooling assembly includes a jacket body 61 and a cover plate 62. The jacket body 61 is arranged in the semi-circumferential direction near the top of the reactor body 1. The cover plate 62 is arranged at both ends of the jacket body 61 to form a cooling water channel between the jacket body 61, the cover plate 62 and the reactor body 1. The jacket body 61 is provided with a water inlet 63 and a water outlet 64 communicated with the cooling water channel. The second cooling assembly includes at least two cooling water pipes 65 extending along the axial direction of the reactor body 1. The third cooling assembly includes at least two cooling water connecting pipes 66 extending along the axial direction of the reactor body 1. The cooling water channel, the cooling water pipes 65 and the cooling water connecting pipes 66 are all connected to a cold water source, and the cold water source is connected to a controller.

[0068] It should be noted that when the temperature of the inner cavity of the reactor body 1 exceeds the preset temperature, the controller controls the cold water source to pass cooling water into the cooling water channel, the cooling water pipe 65 and the cooling water connecting pipe 66. The cold water source is connected to the water inlet 63 connected to the cooling water channel, so that the cooling water of the cold water source can enter the cooling water channel from the water inlet 63 and flow out from the water outlet 64 to reduce the temperature of the reactor body 1. When the thermometer 102 detects that the temperature of the inner cavity of the reactor body 1 drops to the preset temperature range, the controller controls the cold water source to stop passing cooling water into the cooling water channel, the cooling water pipe 65 and the cooling water connecting pipe 66.

[0069] The temperature of the inner cavity of the reactor body 1 should be controlled to be above the melting point of molten sulfur and below the melting point of sulfur hexafluoride to ensure that the molten sulfur will not solidify due to the temperature being lower than the melting point.

[0070] In the above embodiment, the fluorine gas inlet 3 is provided with a second connecting pipe and a second flange connected to the fluorine gas source, the sulfur inlet 2 is provided with a third connecting pipe and a third flange connected to the sulfur supply device, the third connecting pipe extends to a position below the axis of the reactor body 1, and the gas outlet 4 is provided with a fourth connecting pipe and a fourth flange connected to the gas treatment device. The second connecting pipe, the third connecting pipe and the fourth connecting pipe are all arranged through the cooling water channel, and the fluorine gas source, the sulfur supply device and the gas treatment device are all connected to the controller.

[0071] It can be understood that the connection between the reactor body 1 and the fluorine gas source is achieved by arranging the second connecting pipe and the second flange, the connection between the reactor body 1 and the sulfur supply device is achieved by arranging the third connecting pipe and the third flange, and the connection between the reactor body 1 and the gas treatment device is achieved by arranging the fourth connecting pipe and the fourth flange. In addition, the second connecting pipe, the third connecting pipe and the fourth connecting pipe are all arranged through the cooling water channel to support the cooling water channel.

[0072] First, the controller controls the sulfur supply device to introduce molten sulfur to a preset height into the inner cavity of the reactor body 1, and then controls the fluorine gas source to introduce fluorine gas into the inner cavity of the reactor body 1, so that the fluorine gas reacts with the molten sulfur to release a large amount of heat and generate sulfur hexafluoride. The sulfur hexafluoride gas is discharged from the inner cavity of the reactor body 1 through the gas outlet 4. At the same time, the gas treatment device is controlled to start, and the sulfur hexafluoride gas passing through the gas treatment device is treated. Finally, the treated sulfur hexafluoride gas is collected in a gas storage tank.

[0073] Among them, in this embodiment, the third connecting pipe extends to a position below the axis of the reactor body 1 to ensure efficient reaction of sulfur and fluorine gas, but in practical applications, there is no limitation to this as long as the above technical effects can be achieved.

[0074] As a preferred embodiment, the discharge port 5 is provided with a square pipe, which is connected to the waste treatment device through a square flange, and the waste treatment device is connected to the controller.

[0075] It should be noted that the discharge port 5 is connected to the waste treatment device by arranging a square pipe and a square flange. After the reactor body 1 is used for a period of time, the discharge port 5 is opened, and the controller controls the waste treatment device to treat the discharged debris.

[0076] In the above case, the heat-insulating structure 7 includes a heat-insulating layer 71 and a bracket body 72 disposed on the heat-insulating layer 71 .

[0077] It can be understood that the thermal insulation layer 71 is an interlayer with thermal insulation functions. The molten sulfur added into the inner cavity of the reactor body 1 is easy to solidify and agglomerate into a solid state in an environment below the melting point. When the molten sulfur is not added into the inner cavity of the reactor body 1, in order to avoid the influence of the external environment to cause the molten sulfur to solidify, the thermal insulation structure 7 is arranged in the lower half of the reactor body 1, and the bracket body 72 is arranged in the thermal insulation layer 71 to support the thermal insulation layer 71.

[0078] In the above embodiment, a saddle 11 is provided at the bottom of the reactor body 1 , and a pad is provided at the position where the saddle 11 abuts against the reactor body 1 .

[0079] It should be noted that the reactor body 1 is supported and fixed by providing the saddle 11 .

[0080] In summary, in the sulfur hexafluoride reactor provided by the utility model, sulfur is injected into the inner cavity of the reactor body 1 through the sulfur inlet 2, and steam is generated in a heated state, which reacts with the fluorine gas coming out of the fluorine gas inlet 3 to generate sulfur hexafluoride, and is discharged from the gas outlet 4. By arranging the gas guide structure 8 and the semicircular baffle 9, the control of the fluorine-sulfur reaction is strengthened, the reaction efficiency is improved, the slagging operation of the sulfur liquid surface is facilitated, and the entrainment amount of fluorine gas at the gas outlet 4 is reduced.

[0081] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0082] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0083] The above is a detailed introduction to a sulfur hexafluoride reactor provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
