A coke tower decoking device for needle coke production process

Abstract

The invention provides a coking tower decoking device used in the production process of needle coke, which belongs to the technical field of coking equipment and includes a coking tower, an outlet pipe, an outlet flange, a mounting cover, a driving motor, a driving gear, a driven gear and Scraping spray rack structure, the outlet pipe is welded at the lower part of the coking tower; the outlet flange is welded at the lower part of the outlet pipe; the installation cover bolt is installed at the upper part of the coking tower; the drive motor bolt It is installed on the upper right side of the installation cover; the driving gear is arranged on the inner side of the installation cover. The arrangement of the liquid suction pipe, the liquid storage tank and the booster pump of the present invention uses the booster pump to extract the water liquid in the liquid storage tank through the liquid suction pipe, so as to pass through the catheter tube, the liquid introduction tube, the confluence tube and the sealed bearing Finally, through the longitudinal transmission pipe and the transverse feed pipe, the water is sprayed from the nozzle to the inner wall of the coking tower, thereby increasing the cleanliness of the inner wall of the spraying coking tower.

Description

technical field [0001] The invention belongs to the technical field of decoking equipment, in particular to a coke tower decoking device used in the production process of needle coke. Background technique [0002] Coking is an oil refining process, mainly used for the processing of residual oil, especially low-quality vacuum residual oil. Coking uses heavy oil, residual oil, and even asphalt as raw materials. After being heated, it enters the coking tower, where cracking and condensation reactions occur under a certain temperature and pressure, and products such as gas, gasoline, wax oil, and coke are produced. During the coking process, because the coke is slowly deposited in the coking tower, the coke and the wall of the coking tower will be tightly fitted, and it is very difficult to fall off. If these cokes are not removed in time, it will seriously affect the use of the coking tower , and even affect the quality of coking products. [0003] However, the existing cokin...
