Description

Technical Field

[0001] The utility model relates to the technical field of dry coke quenching production, in particular to a dry coke quenching nitrogen replacement device. Background Art

[0002] The coking industry is an important basic energy raw material industry. The coking industry has made great progress in production capacity, technological progress, scientific and technological innovation, energy conservation and emission reduction, and industrial chain construction. It has built a complete industrial system, and the energy structure will continue to develop in the direction of green and low-carbon. Traditional coke production adopts wet quenching technology, which not only consumes a lot of energy, but also emits a large amount of particulate matter and atmospheric pollutants represented by SO2, H2S, etc., and difficult-to-treat solid wastes such as phenol cyanide water and tar residue. The high-energy consumption and high-emission production process has caused resource waste and environmental pollution, hindering the rapid development of the coking industry. Compared with the traditional production process, dry quenching technology can properly reduce the diffusion pollution generated during the quenching process, effectively control the dust content in the surrounding air, and has the advantages of energy saving and environmental protection. At the same time, it can also improve the production quality of coke and has outstanding application value.

[0003] When the existing nitrogen replacement device discharges nitrogen into the dry quenching furnace, it neutralizes the inhaled air by discharging it into the bellows and then flowing into the dry quenching furnace. However, when the air is inhaled for a long time, due to the influence of the processing environment, the external air contains impurities such as dust, which seriously interferes with the nitrogen replacement and gradually reduces the neutralization efficiency, which easily causes the coke in the dry quenching furnace to burn. Due to the large amount of coke, the oxygen content in the circulating gas is high due to incomplete combustion, which is not convenient to use. Therefore, we propose a dry quenching nitrogen replacement device with easy-to-use functions, which is urgently needed to be developed. Utility Model Content

[0024] Please refer to Figure 1-7, one end of the discharging pipeline 33 far away from the dust suction device 32 is movably connected with a hose 34. One end of the hose 34 far away from the discharging pipeline 33 is communicated with the air box 31. The contact area between the hose 34 and the discharging pipeline 33 and the air box 31 is sealed. Fixing plates 35 are connected to both sides of the air box 31.

And the plurality of belt pulleys 311 are connected by a belt in a transmission manner. One end of the rotating rod 36 is connected with a disc 312.
