Abstract

The invention discloses a heat conduction oil online regeneration composite additive. The composite additive comprises an amine antioxidant, a phenol antioxidant, a detergent, a dispersant, and the balance of base oil. The invention also discloses a preparation method of the composite additive, and a conductive oil online regeneration effect comparison method using the composite additive. The heat conduction oil online regeneration composite additive effectively improves the oxidation resistance of heat conduction oil in the use process, delay or prevent oxidation of the heat conduction oil, decompose deterioration products in a system, improve the heat conduction effect and reduce the energy consumption of the system; the composite additive prolongs the service life of the heat conduction oil and a boiler, and improves the running safety of the boiler; and the composite additive improves the running condition of the boiler system without heat conduction oil replacement or shut-down, and also realizes no cleaning of the boiler, no generation of a waste liquid and no environmental pollution.

Description

technical field [0001] The invention relates to a heat conduction oil additive, in particular to a heat conduction oil online regeneration composite additive. Background technique [0002] Heat transfer oil refers to the organic heat carrier medium used for boiler heat transfer. The heat transfer oil in the prior art is mainly divided into mineral heat transfer oil and synthetic heat transfer oil. It is generally believed that the life of heat transfer oil can reach about 3 years under the conditions of use limited by its standard. However, due to the different boiler environments of various enterprises, or the failure to follow the correct operating specifications during use, the heat transfer oil is often in conditions beyond the use limit during use, and it is scrapped when it is used for less than 3 years. [0003] Existing heat transfer oil is blended by adding appropriate amount of additives to base oil. Additives are added to improve thermal stability, oxidation res...
