Abstract

The invention relates to the technical field of cleaning agents, particularly provides an online cleaning agent composition for heat conduction oil and a cleaning method, and aims at solving the problem that heat conduction oil cannot be cleaned in an online way. The cleaning agent composition comprises the following raw materials in parts by weight: 20 to 30 parts of base oil, 2 to 12 parts of an ashless dispersant, 18 to 28 parts of a clearing agent, 2 to 12 parts of a surfactant, and 30 to 45 parts of washing agent. According to the online cleaning method, online cleaning is performed on heat conduction oil through the cleaning agent composition, cooling is not required under the condition that a heat conduction oil system is normally operated, the cleaning agent composition is added into the heat conduction oil system, coked oil dirt on pipe walls is cleaned according to a compatibility principle, the online cleaning of the heat conduction oil is realized, the normal operation of the system is not affected, the phenomenon that pipes are blocked by dirt does not occur, the cleaning efficiency is higher than 98 percent, heat conduction can be improved, and energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, and specifically provides an on-line cleaning agent composition for heat transfer oil and a cleaning method. Background technique [0002] During the long-term use of the heat transfer oil heating system, due to the high-temperature oxidation of the heat transfer oil and the overheating in the heating furnace, the physical changes of the heat transfer oil series, such as the increase in viscosity, carbon residue, and acid value, will form insoluble matter in the heat transfer oil. Deposits on the inner surface of the system cause scaling on the heat transfer surface, forming a large amount of scaling and carbonization inside the system, which affects the normal use of the system to a certain extent, resulting in reduced flow, insufficient heating temperature, and reduced thermal efficiency. Seriously, it will block the pipeline and cause the surface of the heating system pipeline to burn ...
