Anti-tartar detersive for quenching oil column of ethylene unit

The invention relates to an anti-tartar detersive for a quenching oil column of an ethylene unit. In order to solve the problems of the anti-tartar and cleaning of the quenching oil column, the invention provides the anti-tartar detersive for the quenching oil column. The anti-tartar detersive can inhibit the generation of dirt from the source; meanwhile, the detersive can also eliminate the generated dirt in the quenching oil column on line, thus providing necessary conditions for the long period operation of the ethylene unit. The anti-tartar detersive for the quenching oil column of the ethylene unit of the invention is characterized in that according to weight percentage, phenolic antioxidant is 1-18%, phosphorus metal ion deactivator is 8-20%, amine inhibitive substance is 5-35%, thiazolinyl succinimide dispersant is 2-18%, solvent is 30-70%; the substances are put into a container for heating, stirred and mixed evenly and cooled to room temperature, and then filtered to obtain the product.
