Coke tower decoking device for needle coke production process

Abstract

The invention provides a coke tower decoking device for a needle coke production process, which belongs to the technical field of decoking equipment, and comprises a coking tower, an eduction tube, aneduction flange, a mounting cover, a driving motor, a driving gear, a driven gear and a scraping jet frame structure, the eduction tube is welded at the lower part of the coking tower; the leading-out flange is welded at the lower part of the leading-out pipe; the mounting cover is mounted at the upper part of the coking tower through bolts; the driving motor is mounted on the right side of the upper part of the mounting cover through bolts; and the driving gear is arranged on the inner side of the mounting cover. Through the arrangement of the liquid pumping pipe, the liquid storage tank andthe booster pump, water liquid in the liquid storage tank is pumped through the liquid pumping pipe by utilizing the booster pump, so that the water liquid is sprayed from the spray head to the innerwall of the coking tower through the liquid guide pipe, the liquid leading-in pipe, the confluence pipe and the inner ring of the sealing bearing and finally through the longitudinal transmission pipe and the transverse material conveying pipe; therefore, the cleanliness of the inner wall of the jet coking tower is improved.

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...
