First, we need to clarify the reasons for scale formation. The main components of scale are alkaline salts such as calcium and magnesium. When the concentration of these salts in the water exceeds a certain limit, scale will form. The working principle of the steam generator determines that it is prone to scale. After heating, dissolved substances in the water will crystallize and deposit on the inner wall of the steam generator to form scale.
To solve the problem of scale in steam generators, we can take the following cleaning methods:
1. Acid cleaning agent cleaning method
This is a common and effective cleaning method. Choose a professional acid cleaning agent for steam generators and add it to the steam generator according to the proportions in the instructions. Then start the steam generator to heat, allowing the acidic cleaning agent to fully contact and dissolve the scale. After heating for a period of time, turn off the steam generator, drain the cleaning fluid, and rinse the steam generator thoroughly with clean water to ensure that the cleaning agent is completely removed.
2. Mechanical cleaning method
Mechanical cleaning method is suitable for more stubborn scale. First, disassemble the steam generator and remove the parts covered by scale. Then, use tools such as a wire brush or sandpaper to scrub or sand away the scale. It should be noted that when scrubbing, you must avoid causing damage to the equipment and pay attention to your own safety. After cleaning, reassemble the steam generator.
3.Electrochemical cleaning method
Electrochemical cleaning method is a relatively efficient cleaning method. It uses electric current to stimulate the displacement of molecules inside the scale, thereby dissolving the scale. When cleaning, you need to connect the positive and negative poles of the steam generator to the power supply respectively, and then use current to stimulate the chemical reaction inside the scale. This method can quickly dissolve scale and cause less damage to the equipment.
It should be noted that when cleaning the steam generator, be sure to make sure the equipment is shut down and unplug the power plug to avoid accidents. In addition, wear relevant protective equipment when cleaning to ensure physical safety.
Steam generators are indispensable equipment in industrial production, and scale will have a certain impact on their normal operation. By using appropriate cleaning methods, we can effectively solve the scale problem, extend the service life of the steam generator, and ensure its working efficiency.
