AI Technical Summary

Technical Problem

In existing delayed coking units, the storage tank is clogged with fine coke particles, causing blockage of the filtration system, which affects water level monitoring and pump operation, increases equipment maintenance costs, and frequent coke removal operations affect production efficiency and safety.

Method used

A swirling pipe and a central flushing pipe are installed at the bottom of the water storage tank. The jet nozzle drives the water to rotate, and the swirling and flushing reduce the deposition of coke powder, increase the effective volume, and reduce the amount of manual coke removal work.

Benefits of technology

It significantly reduces coke powder deposition, improves the stability and safety of equipment operation, reduces maintenance costs, enhances production efficiency, and avoids equipment failures caused by deposition.
