Description

TECHNICAL FIELD

[0001] The utility model relates to a dust removal folding plate for coke quenching tower, which belongs to the technical field of coke quenching tower dust removal. BACKGROUND

[0002] Wet coke quenching is a method of directly spraying water on high-temperature coke to reduce the temperature by using coke quenching vehicles to transport the high-temperature coke to a coke quenching tower. Several groups of water spraying heads are installed on the top of the coke quenching tower to directly spray water to reduce the temperature, which produces a large amount of steam that is discharged from the top of the coke quenching tower. In the wet coke quenching process, a large amount of steam is generated when water meets high-temperature coke, and the steam, mixed with tar dust and coke dust, is thrown into the air, which seriously pollutes the environment. Therefore, a dust removal device is installed on the top of the coke quenching tower. The common dust removal device usually uses a dust removal folding plate. When the dust and steam rise, the shape and angle of the dust removal folding plate make the dust and steam condense on the dust removal folding plate, achieving the effect of adsorbing and removing dust.

[0003] In the process of condensation and adsorption of dust, the structure of the dust removal folding plate is insufficient in strength and is prone to bending, which reduces the dust removal effect. In particular, when the dust removal folding plate is in a high-temperature and high-humidity environment for a long time, harmful gases such as sulfides mixed in the dust and steam can easily corrode the dust removal folding plate, which destroys the internal structural stability of the dust removal folding plate, thereby reducing the bending resistance of the dust removal folding plate structure.

[0008] Preferably, the corner where the wave peak of the wave surface is located is an obtuse angle. The wave surface can improve the longitudinal bending strength of the dust removal baffle, and can also prolong the steam and dust path, increase the contact time of the steam and dust on the wave surface, and further improve the dust removal effect.

[0009] Preferably, the obtuse angle between the first plate body and the second plate body is 100-120°, and the corner where the wave peak of the wave surface is located is 150-160°.

The transverse reinforcing rib and the longitudinal reinforcing rib are arranged to enhance the bending strength of the connection between the first plate body and the second plate body.

[0011] Preferably, the thickness of the protective layer is 80-100 microns. The protective layer can effectively improve the high-temperature and high-humidity resistance and corrosion resistance of the dust removal baffle, and protect the reinforcing rib and other structures, so that the structural strength is more stable.

[0024] The specific working mode of the utility model is:

[0025] When the coke quenching tower is working, the wet coke quenching produces a large amount of steam, and the steam mixed with tar dust and coke dust flows upward. The steam and the dust meet the second plate body 3 of the dust removal folded plate 1 made of glass steel, condense on the wave surface 102, and concentrate on the wave surface 102, and then the remaining steam and dust continue to flow upward along the dust removal folded plate 1 and condense at the obtuse angle structure formed by the end of the first plate body 2 and the end of the second plate body 3.
