At present, the traditional hot coke water cooling coke quenching (wet coke quenching) in the coke making industry is basically replaced by inert gas flow cooling coke quenching, and the dry coke quenching technology utilizes the heat exchange between the cold inert gas and the red hot coke in a dry coke quenching furnace to cool the red coke, thereby being an effective technical measure for energy conservation and environmental protection in the coke quenching process. The key equipment of the dry quenching system is a dry quenching furnace, and the quenching process of the dry quenching furnace is as follows: the red coke discharged from the coke oven enters the dry quenching furnace from the top, the cold inert gas flow enters the dry quenching furnace from the bottom, is cooled by the inert gas flow flowing upwards in the process of downward displacement of the red coke, the red coke is extinguished and cooled, is discharged from the bottom, and is collected by a chute and enters an air flow collecting loop after being heated to become high-temperature hot air flow, and then leaves the dry quenching furnace through a hot air flow discharge pipe. Obviously, the stability of the dry quenching furnace structure and the optimization of the performance are technical problems to be solved urgently.
In the use process of the dry quenching furnace, although the furnace body adopts a refractory material with good high-temperature performance, high compressive strength and good wear resistance and thermal shock resistance as a furnace lining, the damage and the abrasion are occasionally generated in the use process, in particular to the position of a supporting inclined wall (commonly called as a bracket) at the lower part of an airflow collecting loop. The weight of the refractory material of the inner wall of the airflow collecting loop of the existing dry quenching furnace is mainly fallen on the supporting inclined wall which is inclined inwards from the outer wall and is arranged in a ring shape, and meanwhile, the supporting inclined wall also needs to bear the impact of downward flowing coke and the scouring of the upward flowing cold air carrying coke powder, and the strong thermal stress caused by the temperature change between 300 ℃ and 700 ℃, so the universal service life of the structure is about three years on average. The improvement and the concrete implementation structure of the part are not few by related engineering technicians, but the generated technical effect is not obvious, and how to thoroughly solve the technical problems that the coke oven is easy to damage and has short service life is an urgent need to be solved.
