description The invention discloses a physical and chemistry mixed cleaning technique of a reactor heat exchanger, comprising the following steps: (1) carrying out physical cleaning on a heat transfer tube of the heat exchanger; (2) carrying out chemical cleaning; and (3) carrying out passivating treatment by passivator. The physical and chemistry mixed cleaning technique of the reactor heat exchanger provided by the invention has the advantages that the cleaning effect is good, the cleaning efficiency is high, the cleaning cost is reduced, the heat exchanger is prevented from being corroded and rusted, and harms to working personnel and environment in the cleaning process can be reduced.
