Description

Technical Field

[0001] The utility model relates to the technical field of distributor structures, in particular to a device for extending the service life of a dry coke quenching distributor. Background Art

[0002] Currently, coking plants widely use dry coke quenching (CDQ) equipment. A hoist lifts a coke drum filled with red coke and delivers it to the top of the CDQ furnace. The coke is then loaded into the CDQ furnace via a loading device with a distributor. In the CDQ furnace, the coke directly exchanges heat with the inert gas. As the coke cools, the heat is removed by the inert gas and recycled. Typically, a CDQ loading device is installed at the top of the CDQ furnace. This device receives the red coke hoisted by the hoist and distributes the red coke so that it falls evenly into the CDQ furnace, allowing for sufficient heat exchange with the nitrogen.

[0003] During production, the distributor is susceptible to deformation or wear from the impact of red coke, resulting in poor distribution and, in turn, uneven heat exchange between the red coke and nitrogen. Because the CDQ charging device is located at the mouth of the CDQ furnace, where temperatures reach approximately 1000°C, maintenance can only be performed during the CDQ furnace's annual overhaul. This is a blind spot for regular inspections. If the distributor is severely damaged, the furnace must be shut down for repairs. This downtime severely impacts red coke production and the steam output of the CDQ waste heat boiler, leading to significant economic losses and a significant reduction in the distributor's service life.

[0004] Existing distributors commonly suffer from the following defects: 1) The lower bell of the distributor wears quickly, resulting in a short service life. This wear affects the overall structural stability, causing the upper and lower bells to loosen and tilt, thus affecting normal operation. 2) During production, the lower bell of the distributor is constantly exposed to the erosion of coke, resulting in severe wear and tear, poor distribution, and uneven coke distribution within the CDQ furnace, affecting quenching efficiency and furnace temperature control. 3) The lower bell of the distributor is easily worn but difficult to replace, requiring the CDQ furnace to be stopped for coke loading. This is time-consuming and complex, severely impacting production rhythm and output efficiency. Therefore, the above issues urgently need to be addressed. Summary of the Invention
