Description

Technical Field

[0001] The utility model relates to the technical field of coke powder cooling, in particular to a coke powder cooling device which is resistant to high-temperature deformation. Background Art

[0002] A coke cooler is a device that cools and discharges high-temperature coke through the equipment. Currently, commonly used coke coolers feature a flanged top that interfaces flush with the tube sheet and inner casing. While widely used, these devices are complex to manufacture and generally ineffective. During use, the inner casing and tube sheet at the feed port are prone to wear and deformation from the high-temperature coke, shortening the lifespan of the tube sheet and steel inner casing, preventing the equipment from meeting its service life. Therefore, we have developed a coke cooler that is resistant to high-temperature deformation to address this issue. Utility Model Content

The outer layer passes through the low-temperature cooling water, and the inner layer is the high-temperature coke powder that needs to be cooled.

This device makes the tube sheet 11 uneven with the flange, and the inner casing 3 is higher than the tube sheet 11 and flush with the flange. The height difference between the tube sheet 11 and the casing is filled with insulating castable 2. The function of the insulating castable 2 is to protect the tube sheet 11 from deformation, reduce the wear of the inner casing 3, and increase the service life of the equipment.

The outer layer passes through the low-temperature cooling water, and the inner layer is the high-temperature coke powder that needs to be cooled. The cooled water is discharged from the drain pipe 6, and the cooled coke powder is transported from the bottom to the downstream equipment for later use. This device makes the tube sheet 11 uneven with the flange, and the inner sleeve 3 is higher than the tube sheet 11 and flush with the flange.
