Heat transfer oil is an organic heat transfer medium. As a medium, the liquid phase circulates in the heat exchange equipment system to achieve the purpose of transferring heat. It is a new energy-saving technology.
1. The shortcomings of heat transfer oil ① The heat transfer oil is easily oxidized during the heating process, the acidity of the oil increases at high temperatures, and the kinematic viscosity also increases.
②The amount of residual carbon increases with increasing temperature, and carbon deposits are formed on the inner wall of the pipeline equipment, which affects the heat transfer effect.
③ Fouling of the heat-conducting oil in the pipeline reduces the flow area of the oil pipeline to varying degrees, and reduces the pipeline's oil-transporting capacity.
④ Fouling caused by heat transfer oil seriously affects production, and equipment life will also be affected.
2. Hazards caused by heat transfer oil dirt ① Reduce the thermal efficiency of hot oil furnace, cause waste of energy, and severely cause equipment accidents.
②So dirt is the enemy of hot oil stove. The fundamental solution to avoid hot oil rate dirt is cleaning and descaling.

Coking and carbon cleaning of thermal oil furnace system: Thermal oil boiler cleaning

The chemical cleaning (heating oil furnace cleaning) adopts China's patented technology, combined with the particularity of the internal structure of the heating oil heating system and the diversity of materials, the following thermal oil furnace cleaning solutions are determined:
Heat transfer oil venting—steam flushing—degreasing—descaling cleaning—rinsing—neutralization and passivation—steam flushing—check acceptance—nitrogen purge—reset heating (1) steam flushing conducts heat in the pipeline Vent the oil and flush the inside of the pipe with steam to remove surface impurities, rust and other dirt.
(2) The purpose of degreasing and degreasing is to remove oily substances in the system, and make the scales infiltrate and transform, creating conditions for the descaling step. The oil stain originally existed on the surface as a rolled oil film. Under the action of preferential wetting after washing, it gradually shrank into oil droplets, and was finally washed away from the surface.
(3) Coking and descaling This procedure is a key step in chemical cleaning. The purpose is to prepare a special coke and descaling agent to chemically react with the scale to form a water-soluble substance that is taken out of the system by the cleaning solution, thereby To achieve the purpose of cleaning and descaling.
Heat-conducting oil is heated and coked on the wall tube, and the coke block is very hard. For many years, our company has concluded from researching the practice of coke-clearing. ——Surface adsorption of dirt and the surface of the object to be washed (furnace tube), which changes the interface and various substances (such as mechanical, electrical and chemical properties); emulsifying—forms a strong interface film, It is beneficial to the stability of the emulsion, and the oily spots will not be easily re-precipitated on the surface of the solid (furnace tube). A builder is added to improve the washing effect. It is conducive to the suspension of dirt particles, prevents the deposition of dirt particles, and adds the effect of temperature (thermal movement) and mechanical force to achieve the optimal washing effect.
(4) Rinse Rinse is a combination of a rinsing solution prepared in accordance with regulations and free ions remaining in the system to further improve the descaling rate and lay the foundation for the neutralization and passivation process.
(5) Neutralization Use the neutralization solution to react with the remaining rinsing solution in the system, so that the pH value in the entire system reaches the specified requirements.
(6) The passivation solution for passivation makes the clean metal surface form a complete and dense passivation protective film.
(7) Rinse with water after cleaning to ensure that all cleaning agents are exhausted and the inside of the tube wall is clean.
(8) After the inspection, acceptance, and cleaning are completed, the contractor first performs a self-inspection on the cleaning quality. After the self-inspection is qualified, the contractor and the user unit jointly organize the inspection and acceptance. After the inspection is qualified, both parties sign a cleaning acceptance report.
(9) Nitrogen purge In order to discharge as much as possible the residual water in the pipeline, it can be purged with nitrogen or compressed air.

Heat transfer oil (organic heat carrier) is an excellent heat transfer medium. It has the characteristics of high temperature and low pressure heat transfer, high thermal efficiency, uniform heat transfer, accurate temperature control, and obvious energy saving effects. Therefore, it is used in more than sixty industries and sectors. But no matter they are synthetic or mineral oil, they are all organic matter-that is, alkanes, naphthenes, aromatics and their derivatives. They run in a hot oil furnace for a long time at high temperature and will crack. The main products of the above-mentioned hydrocarbon cracking reaction laws are ethylene and propylene. At higher temperatures, ethylene passes through the acetylene stage to generate carbon:

In addition, the carbon-forming coking reaction has a certain law. It is a typical series of reactions. The common feature is that as the temperature increases and the reaction time increases, hydrogen is continuously released, and the hydrogen content of the residue (tar) gradually decreases. The hydrogen ratio (RC / h), molecular weight, and gravity are gradually increasing, that is, the raw hydrocarbons are gradually dehydrogenated and condensed, and the aromatic hydrocarbons with a single ring or a small number of rings are converted into cycloaromatic hydrocarbons, and then into fused aromatic hydrocarbons. Asphaltene (it is mainly crystalline condensed condensed aromatic ring, its chemical structure is unknown). It is further transformed into carbocyanine (it is a condensed condensed ring aromatic ring with a larger molecular weight and lower hydrogen content). It is further converted into polymer coke.

Thermal oil furnace cleaning The hydrogen content of liquid and solid products gradually decreases. Figure 1 Schematic diagram of the stepwise dehydrocondensation and dehydrogenation cross-linking of aromatic hydrocarbons during the cracking of aromatics.




In short, during the cracking process of the raw hydrocarbon, two types of reactions, namely, molecular decomposition and molecular binding, actually occur. The product of small-molecule light components is generated, and the initial boiling point and flash point of the thermal oil are reduced. The formation of condensates of macromolecules increases the viscosity of the heat-conducting oil, and the hydrogen content in the molecules becomes smaller and smaller, until coking produces carbon.
The heat-conducting oil furnace is a tube furnace. The heat-conducting oil is cracked in the furnace tube, and the inner wall of the furnace tube is coked, which will cause the following serious effects:
(1) The surface temperature of the furnace tube rises, because the thermal conductivity of the coking layer is much smaller than that of steel. Where there is coking, the local thermal resistance increases, and the radial temperature gradient of the furnace tube becomes larger. Causes hot spots on the surface of the furnace tube and affects the life of the furnace tube.
(2) The pressure loss of the furnace tube increases, the coking phenomenon is serious and even the furnace tube is blocked.
(3) If the surface of the steel pipe is relatively rough (such as a centrifugal casting pipe), it is easy to carburize, making the strength of the steel pipe worse, and sometimes the furnace pipe cracks.
Therefore, in the technology that uses thermal oil as a heat carrier, it is necessary to prevent cracking from causing coking as much as possible.
