Add chemical cleaning agent to disperse and discharge the floating rust, scale and oil stain in the equipment, and restore the clean metal surface. Also pay attention to the PH value of the cleaning agent, which can also be said to be the concentration. Not too high or too low, otherwise the scale may not be cleaned or the inner wall of the steam generator may be damaged.
Descaling method of steam generator
Although the scale in the steam generator lining is not insoluble, it is time-consuming and laborious, and it will also delay production. In order to ensure the normal operation of the equipment and avoid economic losses, it is the key to fundamentally solve the scaling problem, which involves the water supply and maintenance of the steam generator.
1. In the case of high hardness of steam generator feed water, it is suggested to match with soft water processor, which can effectively filter calcium and magnesium ions in water, activate water quality and avoid scaling in the later stage.
2. The correct maintenance method can effectively prolong the service life of the steam generator, such as discharging sewage under pressure after each equipment use, and avoiding impurities or calcium and magnesium ions in the water from depositing on the tank bottom to form scale.
Steam generator feed water requirements
The thermal conductivity of scale is only a few tenths of that of metal, which means that the generation of scale will directly affect the heat transfer efficiency of steam generator. In order to achieve the required thermal efficiency, the equipment only needs to increase heat, resulting in deformation, bulging, cracks and even rupture.
To sum up, chemical solvents can remove the scale from the inner container of steam generator, but preventing the scale from the source can fundamentally solve the problem, which can not only prolong the service life of steam generator, but also avoid delaying production and save costs for users.
