Through investigation and analysis, the bracket brick with the inclined air duct has the following technical problems in the production process of the dry quenching furnace:
the inclined air duct is the heart part of the whole dry quenching furnace, the lower part is connected with the cooling section, and the upper part bears the weight of the refractory material of the annular air duct. The structure of the dry quenching furnace is that the inclined air duct is the key, and the part is easy to damage. On one hand, the bracket of the coke dry quenching inclined air duct bears the weight (about 200 t) of the refractory material in the upper partition wall and the annular air duct; on the other hand, the refractory material at the inclined air duct part has a severe working environment and is influenced by the effects of temperature fusion, rapid cooling and rapid heating, strong airflow scouring, coke friction, chemical etching and the like for a long time, and on the other hand, the structure of the bracket brick body of the inclined duct is complex, so that the bearing area of the bracket brick is reduced, and the release of thermal stress in production is also hindered. And then, the single bracket bricks of the inclined air duct are small, and transverse and vertical mortar joints among the bracket bricks are too many, so that the structure is a weak link of the bracket bricks of the inclined air duct, and the overall strength of the bracket of the inclined air duct is seriously influenced. As the single bracket brick in the inclined flue area is small, the construction steps are complicated, and high-quality construction is difficult to achieve. Therefore, the bracket bricks at the inclined air duct part are broken, and the service life of some brackets is more than 1 year and the bracket is damaged in a large area. The utilization rate and the production of the dry quenching furnace are seriously influenced.
The known oblique duct corbel structures therefore suffer from the various inconveniences and problems described above.
