Yanshan petrochemical back-blown coke cutter patented

Recently, the "back-blown coke cutter" developed by the delayed coking device of Yanshan Petrochemical Refinery has obtained the national utility model patent, which effectively solves the problem of coke cleaning on the top of the coke tower and avoids the safety hazards
of manual coking.

The focus cutter is the core device
in the hydraulic defocus process.
Conventional coke cutters do not remove the coke thoroughly enough from the oval head at the top of the coke tower, and there are safety hazards
in personnel and equipment during the coking process.
The "back-blown coke cutter" is small in size, light in weight, simple in installation and operation, and innovatively adopts a nozzle with an oblique 45 degrees to achieve the maximum crushing capacity of the coke layer, strengthens the cleaning effect of the coke in the coke tower, and ensures the safety
of the operator.
