no.1 Use an ultrasonic cleaning machine to clean the heat exchanger
The first step is descaling and cleaning. Add cleaning agent to the ultrasonic cleaning tank and start cleaning, but pay attention to the time and For dosage, if there is too much scale, add more, if there is less scale, add less; in the second step, use clean water to clean, and set the time to about ten minutes. The purpose of this is to remove excess floating rust; in the third step, Add stripper and slow-release agent in proportion to carry out stripping and anti-corrosion cleaning to prevent corrosion of the boiler; in the fourth step, add passivation coating agent to perform passivation coating treatment. After cleaning, the heat exchanger can begin normal operation.
In the production process of the chemical industry, heat exchanger equipment is frequently used, which deposits a lot of crystalline materials. Over time, dirt and scale gradually form, affecting work efficiency and increasing consumption. . In addition to ultrasonic cleaning, there are several common cleaning methods:
1. Chemical cleaning. Chemical cleaning is to select a chemical reagent to contact the heat exchanger by circulating it in the equipment like an industrial fluid, fully contacting the dirt, so that the dirt can be separated from the surface of the heat exchanger and discharged. This kind of cleaning is suitable for existing heat exchangers. The cleaning method is simple to operate and the cleaning is relatively thorough.
2. Manual cleaning. Manually clean the heat exchanger plates with a brush. This method is simple and direct, but compared to the already hard and thick dirt, it is time-consuming and difficult to clean thoroughly.
3. Comprehensive cleaning. When encountering situations that are difficult to clean and cannot be thoroughly cleaned using a single method, a comprehensive method may be used depending on the situation. The comprehensive cleaning method is to first use fluid chemical reagents to soften the dirt, and then use physical methods to clean. The comprehensive use has achieved the purpose of cleaning.
