Plate heat exchangers are used for heating, cooling, evaporation and condensation. It is a good heat exchange equipment for domestic drainage and waste heat utilization. The following plate heat exchanger manufacturers describe in detail the cleaning steps of plate heat exchangers:
One, descaling and cleaning
Add the configured descaling detergent to the circulating water of the cleaning tank in proportion to perform boiler cleaning and descaling. Determine the cleaning cycle time and the amount of reagents according to the amount of scale. After confirming that all the scales are cleaned, go to the next cleaning procedure .
Two, clean with water
After connecting the cleaning equipment to the boiler, clean it with clean water circulation for 10 minutes, check the system status, whether there is any leakage, and clean the floating rust.
Three, peel off anti-corrosion cleaning
Add surface stripper and slow-release agent to the circulating water of the cleaning tank according to the proportion, and cycle for 20 minutes to separate the scale and the cleaned parts. At the same time, the surface of the object without scale is treated with anti-corrosion treatment to reduce the time of descaling The cleaning agent corrodes the cleaned parts.
Fourth, passivation coating treatment
The passivation coating agent is added to the boiler cleaning system for passivation coating treatment, which has a good effect on reducing the corrosion of pipelines and components and the generation of new rust.
The above are the cleaning steps of the plate heat exchanger, I hope it can help you!
