Problems solved by technology

[0003] Problem 1, thermal condensation of heat transfer oil is easy to cause carbon coking in the heat transfer area of ​​the boiler
[0004] Problem 2. Coke scaling on the heat transfer area increases energy consumption and causes fire accidents
The cleaning agent is easy to catch fire, unsafe and easy to cause fire
Both of the above two cleaning methods need to be shut down for cleaning, which will hinder production and processing and affect production efficiency
At present, there is a heat transfer oil online cleaning product on the market. Although it can be cleaned without stopping the furnace, it has been used in a certain range, but due to its general performance, such as long cleaning time, difficult cleaning wastewater, and shutdown during cleaning, etc. Difficult, the residue after cleaning makes the safety hidden danger in the production, and its effect is not very ideal

Abstract

The invention discloses an artificial leather boiler heat-conducting oil on-line detergent and a preparation method thereof. The detergent is prepared from the following raw materials in percentage by weight: CNOOC 150SN, base oil, dialkenyl succinimide, polyisobutenyl succinimide, high-molecular-weight succinimide, high-molecular-weight phenolic antioxidant, octyl/butyl diphenylamine antioxidant and defoaming agent. The detergent implements non-shutdown on-line cleaning in deed, has the advantages of low addition amount and more obvious cleaning effect, can dissolve the solid oil coke, can improve the heat conductivity and can lower the energy consumption, and the cleaning efficiency is up to higher than 98%. The detergent has the characteristics of mild cleaning property and high operational safety, does not influence the normal operation of the system, and does not have the phenomenon of tube blockage by dirt.

Description

technical field [0001] The invention relates to the technical field of processing lubrication and anti-rust cleaning, in particular to an online cleaning agent for boiler heat-conducting oil used for preparing artificial leather and a preparation method thereof. Background technique [0002] Heat conduction oil boiler (heat medium furnace) is a boiler with organic heat medium oil as heat transfer meson. It can obtain higher working temperature under lower operating pressure. , Plastics, coatings, building materials and other industrial enterprises are rapidly popularized and used. If the heat transfer oil furnace is used for too long or the selected heat transfer oil is not good or used improperly, the coking and carbon deposits will block the pipeline and heating surface, reduce the heat transfer efficiency and increase the energy consumption, and finally it will be difficult to meet the production requirements. need. Specific questions include: [0003] Problem 1, therm...
