TECHNICAL FIELD

[0001] The utility model relates to the field of coking wash oil, especially a coking wash oil regenerator. BACKGROUND

[0002] Recently, most of the coking enterprises in China adopt the process of using tubular furnace to heat rich oil to produce crude benzene. It has been proved that using tubular furnace to heat to produce crude benzene is completely correct, because when the benzene content of rich oil and the required benzene content of lean oil are certain, increasing the temperature of rich oil to remove benzene is the most important measure to reduce the direct steam consumption of benzene removal tower. The direct steam consumption is greatly reduced, so that the equipment size of the benzene removal device is correspondingly reduced, and the operation is improved. A regenerator needs to be arranged in the crude benzene distillation system. The function of using the regenerator is to continuously introduce part of the circulating wash oil into the regenerator, heat the wash oil in the regenerator to a certain temperature, make the unsaturated compounds in the wash oil polymerize, and discharge the high-boiling-point residues to ensure the quality of the circulating wash oil. However, the residues are easy to accumulate and block in the residue discharge pipe of the regenerator, and improvement is urgently needed. SUMMARY

[0003] The utility model aims at providing a coking wash oil regenerator, which solves the problem of easy blockage of the residue discharge pipe of the existing coking wash oil regenerator.

[0004] In order to solve the above problems, the utility model provides a coking wash oil regenerator, which comprises a wash oil regenerator body and a discharge anti-blocking assembly, the discharge anti-blocking assembly is installed at the discharge pipe of the wash oil regenerator body, the discharge anti-blocking assembly comprises a supporting ring and a center ring rotatably connected with the supporting ring, an upper shell is fixedly arranged at the top of the center ring, a lower shell is fixedly arranged at the bottom of the center ring, a plurality of first impact balls are arranged between the inner wall of the upper shell and the outer wall of the discharge pipe, and a plurality of second impact balls are arranged between the inner wall of the lower shell and the outer wall of the discharge pipe.

[0005] The coking wash oil regenerator provided by the utility model also has the following technical features:

[0006] Further, an outer wall of the wash oil regenerator body is fixedly provided with a driving assembly for driving the center ring to rotate, the driving assembly comprises a rack fixedly connected with the wash oil regenerator body, a motor fixedly connected with the rack, a gear fixedly connected with the output end of the motor, and a gear ring meshingly connected with the gear, and the gear ring is fixedly connected with the outer wall of the center ring.

[0007] Further, the materials of the first impact balls and the second impact balls are both stainless steel.

[0008] Further, the rotating speed of the motor is 60r / min.

[0009] Furthermore, an upper shell cover is detachably provided on the top of the upper shell, and a lower shell cover is detachably provided on the bottom of the lower shell.

[0010] Furthermore, the upper shell is a conical cylinder, and the lower shell is a cylindrical cylinder.

[0011] The utility model has the following beneficial effects: by driving the center ring to rotate, the rotation of the center ring drives the upper shell and the lower shell to rotate synchronously, so that the multiple first impact balls and the second impact balls continuously impact different positions of the discharge pipe, avoiding material blocking the discharge pipe and keeping the discharge unobstructed.
