Online Purification and Filtration Machine for Heat Transfer Oil

The KD-Q103 Online Purification and Filtration Machine for Heat Transfer Oil is a device independently developed and manufactured by Shandong Kaidi. It enables the purification and filtration of heat transfer oil boiler systems without the need for production shutdown. This product has been granted a utility model patent by the China National Intellectual Property Administration (Patent No.: 202223250229.X).

This equipment achieves online purification and filtration during the normal operation of the heat transfer oil system. It effectively improves the residual carbon index of the heat transfer oil and extends its service life. The entire purification and filtration process involves no chemical reactions, only physical filtration, ensuring that the chemical properties of the heat transfer oil remain unaffected.

I. Background Technology

Heat transfer oil, also known as thermal oil or heat carrier oil, is officially termed as heat transfer oil. Its English name is Heat transfer oil, and it is also referred to as thermal conductive oil or heat medium oil. As an excellent heat transfer medium, it operates under high temperature and low pressure conditions, offering high thermal efficiency, uniform heat transfer, precise temperature control, and significant energy-saving effects. Consequently, heat transfer oil is widely used in over 60 industrial sectors.

During operation, heat transfer oil gradually undergoes cracking and carbonization due to prolonged exposure to high temperatures, leading to the formation of coke deposits that adhere to the pipe walls. On one hand, these coke deposits create an insulating layer, reducing heat transfer efficiency, increasing exhaust gas temperature, and raising fuel consumption. On the other hand, to meet process temperature requirements, the temperature difference across the furnace tube walls can rise sharply. If the temperature difference between the inside and outside of the furnace tube reaches 600–700°C, it can easily cause tube burnout and lead to fire safety incidents. Therefore, regular cleaning of heat transfer oil boilers and pipeline systems is essential. Typically, chemical cleaning agents and physical methods are used to clean the entire system, but this process requires production shutdowns, disrupts normal operations, and carries the risk of equipment corrosion.

II. Product Introduction:

The KD-Q103 Online Purification and Filtration Equipment for Heat Transfer Oil enables online purification and filtration during the normal operation of the heat transfer oil system. It consists of three main components: the first is a centrifugal filtration device, the second is a filtration tank, and the third is a cooling and temperature reduction device. After passing through these three components, impurities, welding slag, and other suspended particles in the oil are effectively filtered. Additionally, the high-precision filter material inside the filtration tank significantly improves the residual carbon index of the heat transfer oil. The improvement rate of residual carbon after a single filtration reaches approximately 20%, demonstrating remarkable effectiveness.

III. Product Features:

1. Enables purification and filtration of the heat transfer oil during normal production operations, avoiding losses associated with shutdowns for filtration or cleaning.

2. Through purification and filtration, it effectively maintains the heat transfer oil and pipeline system, and also helps clean sludge and coke deposits on the inner walls of the heat transfer oil pipelines. (It can be used in conjunction with the KD-L802 High-Temperature Heat Transfer Oil Online Cleaning Agent for enhanced cleaning of the heat transfer oil boiler system.)

2. Works in combination with the KD-L802 High-Temperature Heat Transfer Oil Online Cleaning Agent to enable simultaneous cleaning and filtration.

3. As a new type of online filtration equipment for heat transfer oil, it significantly improves the residual carbon index of the oil, extends its service life, reduces the frequency of oil replacement, and lowers operational costs for enterprises.

Note:

To further enhance the maintenance of heat transfer oil systems and meet the high standards of some enterprises, Shandong Kaidi recommends the use of the "Offline Heat Transfer Oil Filtration Device." This device is easy to install and operate, requiring no on-site management. It not only reduces the management costs of on-site filtration and purification but also significantly improves the performance indicators of the filtered heat transfer oil.
