For commonly used five ink heat exchangers, according to the scaling mechanism, dirt is generally classified into the following categories:

(1) Crystallization fouling: refers to the fouling formed by the deposition of inorganic salt crystals dissolved in supersaturated flowing liquids on the surface of graphite heat exchangers, which is called crystallization fouling. Scale is a common accumulation in industrial equipment. In water cooling systems, calcium and magnesium salts that are supersaturated in water crystallize and deposit on the surface of graphite heat exchangers due to temperature, pH, and other changes, forming scale.

What is the main function of a graphite heat exchanger? As for the graphite heat exchanger, its function is closely related to its use, so let's examine them together.

Graphite heat exchangers are widely used. Radiators used in daily life, condensers in steam turbine devices, and oil coolers on space rockets are all examples of graphite heat exchangers. They are also extensively utilized in the chemical, petroleum, electric power, and atomic energy industries. Their primary function is to ensure the specific temperature required by the medium in the process, and they are also one of the main devices for improving energy utilization efficiency.

Reminder for the precautions of graphite heat exchangers: Overtemperature and overpressure operations are strictly prohibited during use, and sudden changes in temperature and pressure should be prevented. All valves should be opened slowly and gradually adjusted to be larger or smaller. During steam heating, prevent violent impacts of steam. When operating the equipment, heat up slowly, and after the graphite components tend to reach a uniform temperature, slowly increase the pressure until it reaches the normal operating pressure. The operation during the preheating process is very important. Operating steps: First, pass through the cold carrier (material medium), and after the equipment is filled, pass through the hot carrier (steam or hot water); when stopping, first stop the hot carrier (steam or hot water), and after the equipment cools down, stop the cold carrier (material medium). Check the acidity and alkalinity of the condensate water irregularly, analyze the material composition of the tube side and shell side regularly, and verify whether there is any leakage.

Since its establishment more than ten years ago, Nantong Shanjian Anti corrosion has always attached great importance to product quality issues. In order to deeply understand the core concepts of "self inspection, mutual inspection, and special inspection" and their importance in quality management, the aim is to discover quality problems at the source, intercept them in this process, and eliminate them before leaving the factory. On November 5th, the company's anti-corrosion spraying department organized a special training on quality awareness around mastering the responsibilities and specific operating methods of the "three inspection system". The training was given by Wang Rui, the production manager of the company's anti-corrosion spraying department, and more than 10 workshop technicians, team leaders, and frontline workers participated.
