Description

Technical Field

[0001] This application belongs to the field of synthesis furnace technology, specifically relating to a protective device and a synthesis furnace. Background Technology

[0002] The explosion-proof membrane of a hydrogen chloride synthesis furnace is a weak component with lower strength than the furnace body. It can be a circular sheet made of graphite. When abnormal reactions or sudden pressure increases (such as gas mixing imbalance or temperature runaway) cause the pressure inside the hydrogen chloride synthesis furnace to exceed the equipment's tolerance limit, the explosion-proof membrane ruptures due to the unbearable pressure, forming a pressure relief channel. This prevents the continuous accumulation of pressure from causing danger, thus preventing the hydrogen chloride synthesis furnace from exploding or being severely damaged, thereby protecting the equipment and personnel safety.

[0003] The moment the explosion-proof membrane of the hydrogen chloride synthesis furnace ruptures, the high-pressure gas inside the furnace is ejected outward at extremely high speed, giving the membrane tremendous kinetic energy. These high-energy, high-velocity fragments of the explosion-proof membrane can easily penetrate ordinary protective equipment, causing fractures, organ damage, or even fatal injuries.

[0004] Furthermore, when fragments of the explosion-proof membrane hit surrounding equipment or pipelines, they can be ejected, altering their flight trajectory. Alternatively, when the explosion-proof membrane bursts, fragments can be scattered high up and then fall back down, easily causing secondary ejection injuries and increasing the risk of injury to workers.

[0033] Combination Figure 1 and Figure 2 As shown, according to a first aspect of the embodiments of this application, a protective device 100 is provided, including a protective cylinder 101 and a protective cap 102. The protective cylinder 101 is disposed above an explosion-proof membrane 202. The protective cap 102 is disposed on the protective cylinder 101, and the protective cap 102 is located on the side of the protective cylinder 101 opposite to the explosion-proof membrane 202. The protective cylinder 101 and the protective cap 102 are used to intercept explosion-proof membrane fragments generated by the rupture of the explosion-proof membrane 202.

[0034] In this embodiment, the protective cylinder 101 is placed above the explosion-proof membrane 202, so that the protective cylinder 101 can intercept the explosion-proof membrane fragments generated by the explosion-proof membrane 202 bursting, thereby preventing the explosion-proof membrane fragments from splashing to the surroundings and improving the safety of the synthesis furnace 200 operation.

[0035] In this embodiment, the protective cap 102 is installed on the protective cylinder 101, and the protective cap 102 is located on the side of the protective cylinder 101 away from the explosion-proof membrane 202, so that the protective cap 102 can intercept the upward splashing explosion-proof membrane fragments, so as to prevent the explosion-proof membrane fragments from splashing to a high place (far higher than the height of the synthesis furnace) and falling down, thereby further improving the safety of the synthesis furnace 200 operation.

[0036] In this embodiment, the synergistic effect of the protective cylinder 101 and the protective cap 102 can effectively avoid or reduce secondary ejection injuries caused by fragments of the explosion-proof membrane, improve the safety of the working environment for workers, enhance the operational safety of the synthesis furnace 200, and improve the safety of the equipment around the synthesis furnace 200.

[0037] The protective device 100 is applied to the synthesis furnace 200 (e.g., a hydrogen chloride synthesis furnace). When the explosion-proof membrane 202 of the synthesis furnace 200 is triggered due to excessive internal pressure, the protective device 100 will protect the broken pieces of the explosion-proof membrane, which will be intercepted by the protective cylinder 101 and the protective cap 102. This effectively reduces the probability of injury when the explosion-proof membrane 202 of the synthesis furnace 200 is activated, and improves the safety of use.

[0038] In one possible implementation, the protective cylinder 101 is shaped like a cylindrical structure to enhance its effectiveness in preventing fragments of the explosion-proof membrane from splashing outwards.

[0039] It should be noted that the material of the protective cylinder 101 is not limited; for example, it can be iron.

[0040] It should be noted that the material of the protective cap 102 is not limited; for example, it can be iron.

[0041] Combination Figure 2 As shown, in one possible implementation, the protective cylinder 101 is positioned directly above the explosion-proof membrane 202 to effectively prevent fragments of the explosion-proof membrane from splashing outwards, protecting the safety of workers and reducing the risk of impact to surrounding equipment.

[0042] In one possible implementation, the explosion-proof film 202 is made of graphite.

[0043] Combination Figure 2 As shown, in some embodiments, the projection of the protective cylinder 101 onto the plane of the explosion-proof membrane 202 surrounds the explosion-proof membrane 202.

[0044] In this embodiment, the protective cylinder 101 is projected onto the plane of the explosion-proof membrane 202 and surrounds the explosion-proof membrane 202, so that the explosion-proof membrane fragments generated by the explosion-proof membrane 202 bursting enter the interior of the protective cylinder 101 as much as possible, effectively preventing the explosion-proof membrane fragments from splashing to the surroundings, protecting the safety of the staff, and reducing the risk of impact to the surrounding equipment.

[0045] Specifically, the projection of the protective cylinder 101 onto the plane of the explosion-proof membrane 202 surrounds the explosion-proof membrane 202. That is, the area of ​​the opening of the protective cylinder 101 facing the explosion-proof membrane 202 (i.e., the first opening 103) is larger than the area of ​​the explosion-proof membrane 202, so as to effectively prevent the explosion-proof membrane fragments from splashing to the surroundings.

[0046] For example, the protective cylinder 101 is a cylindrical structure. The explosion-proof membrane 202 is a circular structure. The protective cylinder 101 is positioned directly above the explosion-proof membrane 202, and the diameter of the opening of the protective cylinder 101 facing the explosion-proof membrane 202 is larger than the diameter of the explosion-proof membrane 202, thereby effectively preventing fragments of the explosion-proof membrane from splashing outwards.

[0047] Combination Figure 1 As shown, in some embodiments, the protective cylinder 101 includes a first opening 103 and a second opening 104. The first opening 103 faces the explosion-proof membrane 202. The second opening 104 and the first opening 103 are located at opposite ends of the protective cylinder 101. The second opening 104 faces the protective cap 102.

[0048] In this embodiment, the first opening 103 faces the explosion-proof membrane 202, and the area of ​​the first opening 103 is larger than the area of ​​the explosion-proof membrane 202, so as to effectively prevent the explosion-proof membrane fragments from splashing to the surroundings.

[0049] In this embodiment, the second cylinder opening 104 and the first cylinder opening 103 are located at both ends of the protective cylinder 101, that is, one end of the protective cylinder 101 is the first cylinder opening 103 and the other end of the protective cylinder 101 is the second cylinder opening 104. This allows the protective cylinder 101 to prevent the explosion-proof membrane fragments from splashing to the surroundings, while also providing a pressure relief channel. This enables efficient and stable pressure relief of the synthesis furnace 200 (e.g., a hydrogen chloride synthesis furnace), thereby improving the operational safety of the synthesis furnace 200.

[0050] For example, in combination Figure 2 As shown in the figure, the dashed arrows are used to indicate the gas flow direction inside the synthesis furnace 200 when the explosion-proof membrane 202 of the synthesis furnace 200 bursts. The protective cylinder 101 provides a pressure relief channel to improve the operational safety of the synthesis furnace 200.

[0051] In this embodiment, the second cylinder opening 104 faces the protective cap 102, so that the protective cylinder 101 guides the upward-splashing explosion-proof membrane fragments in the direction of movement, causing the explosion-proof membrane fragments to pass through the protective cylinder 101 and move toward the protective cap 102, so that the protective cap 102 can intercept the explosion-proof membrane fragments, basically preventing the explosion-proof membrane fragments from splashing to a high place and falling down, protecting the staff, and improving the safety of the surrounding equipment.

[0052] Combination Figure 1 As shown, in some embodiments, the protective cap 102 includes a cap opening 105. The cap opening 105 is opposite to the second cylindrical opening 104. The size of the cap opening 105 is larger than the size of the second cylindrical opening 104.

[0053] In this embodiment, by having the cap opening 105 opposite to the second cylinder opening 104, the protective cap 102 can successfully intercept the explosion-proof membrane fragments that fly upward through the protective cylinder 101.

[0054] In this embodiment, the size of the cap opening 105 is larger than the size of the second cylinder opening 104. That is, the cap opening 105 is located directly above the second cylinder opening 104, and the area of ​​the cap opening 105 is larger than the area of ​​the second cylinder opening 104, so as to successfully intercept the explosion-proof membrane fragments that fly upward through the protective cylinder 101 and improve the safety of use.

[0055] Combination Figure 1 As shown, in some embodiments, the distance between the sidewall of the protective cap 102 and the axis of the protective cylinder 101 gradually decreases along the direction from the protective cylinder 101 to the protective cap 102.

[0056] Specifically, along the direction from the protective cylinder 101 to the protective cap 102, that is, along the direction from the first opening 103 of the protective cylinder 101 to the second cylinder body.

[0057] Combination Figure 1 As shown, Figure 1 The dashed line L is used to indicate the axis of the protective cylinder 101. Along the direction from the protective cylinder 101 to the protective cap 102, the distance between the side wall of the protective cap 102 and the axis of the protective cylinder 101 gradually decreases. That is to say, the side wall of the protective cap 102 is formed as a whole into a conical structure, and a cavity is formed on the inner side of the protective cap 102, which provides a buffer and guiding space for the upward splashing explosion-proof membrane fragments, and concentrates the flight trajectory of the explosion-proof membrane fragments towards the center of the protective cap 102, further preventing the explosion-proof membrane fragments from splashing to the surroundings and improving the protective effect.

[0058] Combination Figure 1 As shown, in some embodiments, the protective device 100 further includes connecting posts 106. The two ends of the connecting post 106 are connected to the protective cylinder 101 and the protective cap 102, respectively, to form a pressure relief space 109 between the protective cylinder 101 and the protective cap 102. Multiple connecting posts 106 are provided, and the multiple connecting posts 106 are arranged at intervals along the circumference of the protective cylinder 101.

[0059] Specifically, the connecting post 106 is fixed to the outer wall of the protective cylinder 101, and the end of the connecting post 106 facing away from the protective cylinder 101 is connected to the protective cap 102, so that the two ends of the connecting post 106 are connected to the protective cylinder 101 and the protective cap 102 respectively.

[0060] In this embodiment, the protective cap 102 can be stably mounted on the protective cylinder 101 via the connecting column 106, improving the stability and robustness of the overall structure of the protective device 100. The connecting column 106 also creates a gap between the protective cylinder 101 and the protective cap 102, forming a pressure relief space 109 between them. This allows for efficient and stable pressure relief of the synthesis furnace 200 (e.g., a hydrogen chloride synthesis furnace), keeping the furnace body within a safe pressure range. Through the synergistic effect of the protective cylinder 101, the connecting column 106, and the protective cap 102, the functions of interception, protection, and safe pressure relief are organically unified, comprehensively improving the operational safety of the synthesis furnace 200.

[0061] It should be noted that the specific dimensions of the gap between the protective cylinder 101 and the protective cap 102 are not limited and can be set according to the pressure of the synthesis furnace 200.

[0062] It should be noted that the material of the connecting post 106 is not limited. For example, it can be stainless steel to give the connecting post 106 good strength and corrosion resistance.

[0063] In some embodiments, the protective device 100 further includes a corrosion-resistant material layer coated on the surfaces of the protective cylinder 101 and the protective cap 102.

[0064] In this embodiment, an anti-corrosion material layer is coated on the surface of the protective cylinder 101 to improve its corrosion resistance and service life. Similarly, an anti-corrosion material layer is coated on the surface of the protective cap 102 to improve its corrosion resistance and service life.

[0065] In this embodiment, the anti-corrosion material layer is made of an anti-corrosion material. The specific type of anti-corrosion material is not limited; for example, it could be fluorocarbon paint.

[0066] In one possible implementation, a layer of anti-corrosion material is coated on the inner wall of the protective cylinder 101 and the inner wall of the protective cap 102.

[0067] Combination Figure 1 and Figure 2 As shown, according to a second aspect of the embodiments of this application, a synthesis furnace 200 is provided, including a synthesis furnace body 201 and a protective device 100 as described above. The synthesis furnace body 201 is provided with an explosion-proof membrane 202. The protective device 100 is disposed on the synthesis furnace body 201, and the protective device 100 is located above the explosion-proof membrane 202.

[0068] In this embodiment, the synthesis furnace 200 includes a furnace body 201 and a protective device 100. The protective device 100 is disposed on the furnace body 201 and is located above the explosion-proof membrane 202. Fragments of the shattered explosion-proof membrane are intercepted by the protective cylinder 101 and the protective cap 102, effectively reducing the probability of injury when the explosion-proof membrane 202 of the synthesis furnace 200 is activated, and improving safety. The effectiveness of the protective device 100 is described in the foregoing embodiments of this application and will not be repeated here.

[0069] In this embodiment, the specific structure of the synthesis furnace body 201 is not limited, and it can be the furnace body of a hydrogen chloride synthesis furnace.

[0070] In one possible implementation, the synthesis furnace 200 includes a hydrogen chloride synthesis furnace.

[0071] Combination Figure 2 As shown, in some embodiments, the synthesis furnace 200 further includes a flange assembly 203 and a connecting plate 107. The flange assembly 203 is disposed on the synthesis furnace body 201. The connecting plate 107 is disposed on the protective device 100 and is used to connect to the flange assembly 203. An explosion-proof membrane 202 is disposed on the flange assembly 203.

[0072] In this embodiment, the protective device 100 is connected to the flange assembly 203 via the connecting plate 107, thereby achieving a stable connection between the protective device 100 and the synthesis furnace body 201.

[0073] In this embodiment, the explosion-proof membrane 202 is disposed on the flange assembly 203. Specifically, the flange assembly 203 includes two flanges, and the explosion-proof membrane 202 is disposed between the two flanges so that the explosion-proof membrane 202 is disposed on the synthesis furnace body 201, thereby achieving a seal on the synthesis furnace body 201. It is connected to the flange assembly 203 through the connecting plate 107, so that the protective device 100 is securely installed directly above the explosion-proof membrane 202 to effectively intercept any broken pieces of the explosion-proof membrane.

[0074] In this embodiment, the structure of the connecting plate 107 is not limited. For example, a flange can be used.

[0075] Combination Figure 1 and Figure 2 As shown, in some embodiments, the synthesis furnace 200 further includes a connector 108. The connector 108 is used to connect the flange assembly 203 and the connecting plate 107.

[0076] In this embodiment, the flange assembly 203 and the connecting plate 107 are connected by the connector 108 to fix the protective device 100 to the synthesis furnace body 201.

[0077] In this embodiment, the specific structure of the connector 108 is not limited; for example, it can be a high-strength screw.

The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
