Description

Technical Field

[0001] The utility model relates to the technical field of coke ovens, in particular to a rising pipe fixed ignition assembly. Background Art

[0002] The pollution characteristic of coke ovens is intermittent emission. During the coking production process, when loading coal, pushing coke and quenching coke, the coke oven will emit a large amount of unorganized smoke into the atmosphere, which will cause harm to humans and the environment.

[0003] In the operation of opening the cover of the riser before pushing the coke (referred to as "covering operation"), due to the presence of residual volatile matter in the coke and residual raw gas in the carbonization chamber, unorganized smoke will inevitably be emitted into the atmosphere, and the diffusion point of the unorganized smoke changes with the change of the furnace number. The main components of the residual raw gas are C, H inorganic substances and a small amount of organic matter. By igniting and burning them, their pollution to the atmosphere can be greatly reduced. In the prior art, the cover opening operation and the ignition operation are generally completed manually. The cover opening operation of the riser is performed, and then a torch is raised to ignite the smoke emitted from the riser.

[0004] The disadvantage of the above operation is that it is labor-intensive and can cause the residual raw gas to escape, and may also cause the "blasting" phenomenon. The "blasting" phenomenon occurs because the riser is located at a high position. The moment the riser cover is opened, air mixes with the residual raw gas in the riser, and then the flame of the torch is ignited, and then a deflagration occurs. The "blasting" phenomenon can cause the furnace body to be poorly sealed and leak, and the residual raw gas is directly discharged through the chimney, which indirectly causes environmental pollution.

[0005] The utility model attempts to provide a rising pipe fixed ignition assembly, which can not only reduce the occurrence of "blasting" phenomenon, but also realize the complete combustion of raw gas and reduce the escape of residual raw gas. Utility Model Content

[0018] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0019] like Figure 1 As shown, an embodiment of the utility model provides a fixed ignition assembly of an ascending tube, comprising: an ascending tube 1; a tube cover 2, the tube cover 2 is hinged to the ascending tube 1 through a rotating shaft 4; a fixed leaf 3, the fixed leaf 3 extends along the top and side of the tube cover 2 to the rotating shaft 4, the fixed leaf 3 is fixed to the tube cover 2, and the fixed leaf 3 is fixed to the rotating shaft 4; a fixed ignition gun 5, the fixed ignition gun 5 is arranged on the side of the tube cover 2. The rotating shaft 4 is driven by a cylinder, and the fixed ignition gun 5 is controlled by a remote switch. When the tube cover 2 is opened, the staff triggers the remote switch in time to achieve timely ignition.

[0020] At present, when performing the cover operation, the pipe cover is generally opened first, and then the raw gas is ignited. When the pipe cover is opened, a large amount of air is mixed in, resulting in a deflagration during ignition, commonly known as the "explosion" phenomenon. A large amount of pressure and vibration are generated during the deflagration, which has a serious impact on the operation and service life of the equipment, not only affecting the corporate image, but also affecting the safety of the staff. Deflagration not only affects safety, but also makes the combustion uncontrollable, resulting in a lot of residual unburned raw gas, polluting the atmosphere.

[0021] exist Figure 1 In the illustrated embodiment, the staff can trigger the remote switch in time while the pipe cover is opened to achieve timely ignition, thereby reducing combustion delays and the occurrence of deflagration.

[0022] Further, such as Figure 2 As shown, the riser fixed ignition assembly may also include: an arc-shaped crank 6, which is provided with a downwardly bent arc-shaped crank 6 on one side of the tube cover 2 close to the rotating shaft 4; an arc-shaped sleeve 7, which is bent and extended upward from the side of the riser 1, and the connection between the arc-shaped sleeve 7 and the riser 1 is located below the rotating shaft 4. The inner diameter of the arc-shaped sleeve 7 is larger than the cross-sectional diameter of the arc-shaped crank 6. When the tube cover 2 is closed, the pipe mouth of the arc-shaped sleeve 7 is directly opposite to the end of the arc-shaped crank 6. When the tube cover 2 is opened, the arc-shaped crank 6 can move smoothly in the arc-shaped sleeve 7; a buffer spring 9, which is located inside the arc-shaped sleeve 7, and one end of the buffer spring 9 is fixed to the riser 1; a travel switch 10, which is arranged at the other end of the buffer spring 9. When the end of the arc-shaped crank 6 enters into the arc-shaped sleeve 7, the arc-shaped crank 6 can squeeze and connect the travel switch 10. The travel switch 10 is connected to the fixed ignition gun 5, and the fixed ignition gun 5 is ignited when the travel switch 10 is connected. In order to ensure the safety of the circuit, the connection line between the travel switch 10 and the fixed ignition gun 5 should be as far away from the nozzle as possible.

[0023] When opening the cover, the arc-shaped crank 6 presses the travel switch 10, and at the same time, the travel switch 10 is squeezed by the buffer spring 9, so that the travel switch 10 is connected, and the fixed ignition gun 5 is ignited, thereby realizing the linkage of the cover opening operation and the ignition operation, and realizing timely ignition.

[0024] The arc-shaped crank 6 is a 90-degree arc, the arc-shaped sleeve 7 is a 90-degree arc, the inner diameter of the arc-shaped sleeve 7 is larger than the cross-sectional diameter of the arc-shaped crank 6, and the arc-shaped crank 6 can move smoothly in the arc-shaped sleeve 7. When the cover is opened, when the arc-shaped crank 6 squeezes the travel switch 10 and the buffer spring 9, the buffer spring 9 can be deformed, so that the arc-shaped crank 6 can still continue to move in the arc-shaped sleeve 7 to further open the pipe cover 2. When the pipe cover is closed after the combustion is completed, the buffer spring 9 can also provide assistance to help the pipe cover 2 close.

[0025] If the pipe cover can be opened slowly and ignited in time, a large amount of air can be avoided from mixing in within a short period of time, making the combustion more moderate and avoiding the occurrence of deflagration. When opening the cover in the embodiment of the utility model, the pipe cover 2 is first opened a little. At this time, the arc-shaped crank 6 presses the travel switch 10, and the travel switch 10 is also squeezed by the buffer spring 9, so that the travel switch 10 is connected and the fixed ignition gun 5 is ignited. At this time, since the pipe cover 2 is only opened a little, a large amount of air will not mix in within a short period of time. At this time, the raw gas has been ignited by the fixed ignition gun 5, and a relatively moderate combustion occurs. Since the combustion is relatively moderate, the unburned residual raw gas will also be greatly reduced. In addition, due to the presence of the buffer spring 9, a part of the thrust can be provided, which can prevent the pipe cover 2 from being opened suddenly and can help to achieve the slow opening of the pipe cover.

[0026] Further, one end of the buffer spring 9 is fixed to the riser 1 through the insulator 8, the insulator 8 is fixed to the riser 1, and one end of the buffer spring 9 is fixedly connected to the insulator 8. The insulator 8 is made of a heat insulating material. The insulator 8 is provided to reduce the negative impact of the high temperature of the riser 1 on the service life of the buffer spring 9.

[0027] Further, such as Figure 3 As shown, fixed ignition guns 5 are arranged at multiple positions around the pipe mouth of the riser 1. These fixed ignition guns 5 are all connected to the travel switch 10 or the remote switch. During ignition, multiple fixed ignition guns 5 are connected to ignite at the same time, so as to realize timely and sufficient ignition.

[0028] The fixed ignition assembly for the riser provided by the utility model can perform the operation of opening the riser cover and the ignition operation simultaneously, so that the ignition starts as soon as the cover is opened, so that the raw gas can be ignited and consumed in time, avoiding the risk of deflagration caused by mixing of a large amount of air due to untimely ignition, and the operation is safe.
