High pressure water jet unloading technology uses high-speed water jet to break catalyst agglomerates and recover them. There is no need to enter into the operation personnel inside the tank body. The unloading work is completely carried out by the unloading device itself, and the unloading efficiency is about 20 days less than that of manual operation, which can accelerate the re production process of residue hydrogenation device. A single operation can increase the profits of the enterprise by about 56 million yuan, with obvious economic benefits.
The rated pressure of the high-pressure water jet unloading device is 50MPa, the rated displacement is 240L / min, the radial reaming distance of words / one side is ≥ 300mm, the single axial reaming height is 50mm, and the action range of the unloading nozzle is ≥ 5m.
Usage: The residual oil hydrogenation unit of petrochemical enterprises needs to stop regularly to replace the catalyst. At present, the unloading of the catalyst completely depends on manual work. The operators wear safety protection tools, enter the tank body and use hammer drill to break the caked catalyst and lift it to the tank mouth. The operators clean it in an oxygen free environment, with poor safety and low efficiency.
Based on the calculation of the daily processing of 7000 tons of crude oil and 400 yuan per ton of oil under constant pressure, the loss of about 2.8 million yuan per day of late production is calculated.
