Acetylene gas enters the cracking furnace from the top, where it undergoes self-heating, high-temperature cracking in the cracking section, breaking down the acetylene into carbon black and hydrogen, which are then discharged from the bottom while releasing heat. During production, inspectors can observe the flame inside the cracking furnace through a viewing port. The furnace maintains a slight negative pressure, and the flame normally flows toward the outlet. However, under abnormal operating conditions, flames can erupt from the viewing port, potentially causing burns if inspectors happen to be observing. Utility Model Content

[0028] Refer to the following Figure 1 and Figure 2 The flame elimination device and the cracking furnace according to some embodiments of the present application are described.

[0029] Example 1

[0030] See also Figure 1 and Figure 2 As shown, an embodiment of the present application provides a flame extinguishing device 10, comprising a main body 1 and at least one layer of baffles; wherein the main body 1 is formed with an installation cavity running through its two ends along a first preset direction, multiple layers of baffles are arranged in the installation cavity, and the multiple layers of baffles are arranged in sequence along the first preset direction so that a baffle gap 3 is formed between two adjacent layers of baffles; each layer of baffles includes at least two baffles 2, and at least two baffles 2 are arranged in sequence along the circumference of the installation cavity (that is, the circumference perpendicular to the first preset direction); any baffle forms an acute angle with the first preset direction, and the multiple baffles 2 in each layer of baffles are surrounded by a channel 4 for flame passage, and the multiple baffles 2 in each layer of baffles are arranged in a clustered state in the opposite direction of the extension direction of the flame in the channel 4.

[0031] According to the structure described above, a plurality of layers of baffles are arranged in the installation cavity, and a baffle gap 3 is arranged between the plurality of layers of baffles. That is to say, a diversion structure is arranged inside the viewing hole, so as to divert the flame, thereby reducing the expansion of the airflow, suppressing the flame intensity, reducing the flame outside the viewing hole, avoiding burn accidents for the inspection personnel, and providing better protection for the company's safe production.

[0032] In this embodiment, preferably, Figure 1 As shown, any baffle plate 2 is formed with an auxiliary weakening cavity 5 communicating with the baffle gap 3 for diverting the flame again.

[0033] According to the structure described above, it can be seen that by providing an auxiliary weakening cavity 5 on the side wall of any baffle 2, the flame can be diverted again to further weaken the flame.

[0034] It should be noted that: the auxiliary weakening cavity 5 may not be provided on the side wall of the baffle 2, and only the baffle 2 and the baffle gap 3 may be used to divert and weaken the flame, and the specific selection is made according to actual needs.

[0035] In this embodiment, preferably, Figure 1 As shown, the auxiliary weakening cavity 5 is a T-shaped cavity, that is, the T-shaped cavity includes a main cavity 51 and a neck cavity 52 , and the main cavity 51 is connected to the deflection gap 3 through the neck cavity 52 .

[0036] As can be seen from the structure described above, the larger main chamber 51 increases the amount of flame diversion, and the constricted chamber 52 is provided at the opening of the main chamber 51. This prevents the flame from escaping from the main chamber 51, helping to ensure the flame weakening effect. Of course, the structure of the auxiliary weakening chamber 5 is not limited to this. The main chamber 51 and the constricted chamber 52 have exactly the same dimensions; that is, there is no constriction at the opening, and the main chamber 51 is directly connected to the deflection gap 3. The specific design can be based on actual needs.

[0037] In this embodiment, preferably, Figure 1 As shown, the multiple baffles 2 included in each layer of baffles are evenly spaced along the circumference of the installation cavity.

[0038] According to the structure described above, the multiple baffles 2 in each layer of baffles are evenly spaced along the periphery of the installation cavity, thereby playing a role of uniform diversion. Of course, it is not limited to this. The multiple baffles 2 in each layer of baffles may not be evenly arranged, but may be non-uniformly arranged, depending on actual needs.

[0039] In this embodiment, preferably, Figure 1 As shown, the installation cavity includes a first cavity 111 and a second cavity; wherein, the first cavity 111 and the second cavity are arranged in sequence along a first preset direction and are connected, and the flame can extend along the first cavity 111 and the second cavity in sequence; the side wall of the first cavity 111 close to the second cavity is provided with a neck expansion groove 1111; the multi-layer baffles are all arranged in the second cavity.

[0040] According to the structure described above, an expansion groove 1111 is provided on the side wall of the first chamber 111, so that the initial flame can be appropriately enlarged, which makes it easier to observe. If the initial flame is small, it may be difficult to observe the flame after being weakened by diversion, thereby affecting the judgment of the inspection personnel.

[0041] In this embodiment, preferably, Figure 1 As shown, any deflector plate 2 is formed with a deflecting protrusion 21 facing the deflector, and is used to further weaken the flame. Of course, this deflecting protrusion may not be provided.

[0042] In this embodiment, preferably, Figure 1 As shown, a deflection weakening groove 22 is formed at the head of any deflector 2 close to the channel 4 to further weaken the flame. Of course, this deflection weakening groove 22 may not be provided.

[0044] See also Figure 2As shown, the second embodiment of the present application further provides a cracking furnace, including the flame elimination device 10 described in the above-mentioned first embodiment, and thus has all the beneficial technical effects of the flame elimination device 10, and the same technical features and beneficial effects are not repeated here.

[0045] In this embodiment, preferably, Figure 2 As shown, the cracking furnace further includes a furnace body 20 , and the furnace body 20 is formed with a mounting opening. The flame elimination device 10 is mounted at the mounting opening and communicates with the interior of the furnace body 20 .

[0046] According to the structure described above, the cracking furnace provided in the present application adopts a new type of sight hole structure, namely the flame elimination device 10, and a multi-layer deflector and a deflection gap 3 are arranged inside the sight hole, that is, a diversion structure is arranged inside the sight hole, thereby reducing the expansion of the airflow, suppressing the flame intensity, reducing the flame outside the sight hole, preventing the occurrence of burn accidents, and being safer and more reliable.

[0047] In this embodiment, preferably, Figure 2 As shown, the furnace body 20 is provided with a nozzle 30 , and the nozzle 30 and the flame extinguishing device 10 are located at the same end of the furnace body 20 , and the flame extinguishing device 10 is arranged obliquely relative to the spraying direction of the nozzle 30 .

[0048] According to the structure described above, the flame extinguishing device 10 is tilted relative to the spraying direction of the nozzle 30, which can effectively avoid the nozzle 30 and facilitate observation of the flame.

[0049] Of course, the present invention is not limited thereto. The flame extinguishing device 10 may also be arranged along the spraying direction of the nozzle 30 , and the specific design is based on actual needs.

[0050] In this embodiment, preferably, Figure 2 As shown, the furnace body 20 is arranged in a vertical direction, and a discharge port 201 that can be opened or closed is formed at the bottom of the furnace body 20. A water cooling jacket 40 is also provided on the periphery of the furnace body 20. This part is an existing structure and will not be described in detail here.

[0051] It should be noted that the flame elimination device 10 provided in the present application is not limited to being used in cracking furnaces, but can also be used in other equipment, and the specific selection is based on actual needs.
