Treatment method for removing ethylene cracking tar

The invention relates to the technical field of ethylene cracking tar removal treatment, in particular to a treatment method for removing ethylene cracking tar. The treatment method for removing the ethylene cracking tar is carried out according to the following steps: a pneumatic diaphragm pump is taken as power; a cleaning agent in a cleaning agent storage tank is conveyed into to-be-cleaned equipment or a to-be-cleaned pipeline through metal hose arranged at an inlet of the to-be-cleaned equipment or the to-be-cleaned pipeline, so that the cleaning agent quickly dissolves residual ethylene cracking tar in the to-be-cleaned equipment or the to-be-cleaned pipeline; and the cleaning agent dissolved with the ethylene cracking tar is conveyed into the cleaning agent storage tank through a metal hose arranged at an outlet of the to-be-cleaned equipment or the to-be-cleaned pipeline to be cleaned, and the process is repeated until the ethylene cracking tar left in the equipment or the pipeline is thoroughly clean
