1、 Preprocessing
Thermal oil needs to be pre treated before use, mainly to remove impurities and moisture. Firstly, place the heat transfer oil into a filter for filtration. The filter uses a stainless steel mesh, which can effectively filter out impurities and small particles in the oil. Then, the filtered thermal oil is placed in a dehydration tank for dehydration to remove any moisture. The dehydration tank generally uses centrifugal force to remove water, and vacuum dehydration method can also be used.
2、 Filtering
Filtering is a crucial step in the dehydration process of thermal oil. Choosing appropriate filtering materials and equipment can effectively remove small particles and impurities from the oil while maintaining the stability of the thermal oil. For the size distribution of particles and impurities in thermal oil, the corresponding filtering materials and equipment should be selected according to the filtration accuracy of the equipment to ensure the purity of the thermal oil.
3、 Dehydration
The moisture content in the heat transfer oil is an important factor affecting its effectiveness, and dehydration treatment is required for the heat transfer oil. The main methods of dehydration are vacuum dehydration and centrifugal dehydration. Vacuum dehydration is achieved by placing heat transfer oil into a vacuum dehydration tank and removing its moisture through negative pressure. Centrifugal dehydration is the process of separating water from thermal oil by centrifugation using a rotating centrifuge. Both of these methods have good dehydration effects, and the corresponding dehydration method needs to be selected according to the specific situation.
4、 Dry
After dehydration, thermal oil needs to be dried to remove moisture and improve its purity and stability. The drying method can be carried out through drying, nitrogen drying, or other methods. The drying method is the most commonly used method, which involves placing the heat transfer oil in an oven for drying. This method is simple, easy to implement, and has stable results.
In summary, dehydration of thermal oil is an important step to ensure its effectiveness and work efficiency. This article provides a detailed introduction to the various steps and operating methods of pre-treatment, filtration, dehydration, and drying of thermal oil, hoping to be helpful to everyone.
