1, dosing softening treatment and heat exchanger cleaning dosing softening treatment are simple, efficient and economical, and do not need special water treatment equipment, which is a practical anti-scaling water treatment method.
2. Magnetization anti-scaling treatment. The cleaning principle of magnetized anti-scaling heat exchanger is to use the polarity of water molecules, that is, water molecules are * * * valence compounds. Monomolecular water has polarity and hydrogen bond, and it is polymerized into bimolecular association or multimolecular association.
3. Anti-scaling water treatment with ion bar. Ion bar anti-scaling water treatment is a new type of water treatment equipment. After being applied in hot water circulation system, central air conditioning system and circulating cooling water system, the anti-scaling effect is very good. Especially in the heat exchanger, the application effect will be more obvious, and it is a new type of water treatment equipment with great development prospects.
4. Sodium ion exchange softening treatment: after the heat exchanger is cleaned by sodium ion exchange softening treatment, the hardness and alkali in the water can be removed, and the salt content of the effluent can be improved.
Precautions:
1. Before dismantling the plate heat exchanger, measure the compaction length of the plate bundle and make records.
2. If sundries are found in the short pipes and channels at the medium inlet and outlet, the filter is invalid and should be cleaned in time.
