Severe scaling of the cooling water used in the equipment’s condenser
Thread Content
Many of the unit’s tube-type and spiral-plate condensers use circulating water as the cooling medium; this circulating water does not contain scale inhibitors or algaecides, and currently the scale buildup on the tube walls is around 5 mm thick. I would like to ask my friends whether it’s possible to add hydrochloric acid directly to the recirculation tank to adjust the pH to 4-5 Does it have a descaling effect?
Adding hydrochloric acid can cause corrosion issues; it is recommended to use regular descaling agents instead. I estimate that the return temperature of the coolant water in your cooling system is relatively high. In northern regions, it is recommended to switch to a closed-loop water system, using soft water for circulation and air coolers for cooling water.
Anticorrosion measures are necessary; superhydrophobic coatings for hydrophobic materials can **reduce the problem of scaling**.
Circulating water is not subject to water quality management; even if you handle it this time, what about next time? (The method you mentioned doesn’t work.)
We have descaling devices here; no descaling agent is needed
Adding hydrochloric acid to the water tank results in high chloride levels, which can cause corrosion of the equipment; it is best to keep the pH value between 8 and 8.8
It depends on what type of scale is present in your equipment: carbonate scale, sulfate scale, or silicate scale. For carbonate scale, the Light Rain Frequency-Driven Scale Remover is an effective and environmentally friendly solution at present; however, it is not particularly effective against sulfate scale. In the case of silicate scale, chemical cleaning is recommended.
