The basic principle of plate heat exchanger remove scale

The basic principle of plate heat exchanger remove scale 1) Solution: acid solution easily react with calcium, magnesium, carbonate scale, generate soluble compounds, the plate heat exchanger scale dissolved. 2) The combination of destruction and plate heat exchanger scale. So attached to the metal oxide scale on the surface of the strip. And off. 3) Gas lift: acid solution after react with calcium, magnesium, carbonate scale, produce large amounts of carbon dioxide. Carbon dioxide gas in the process of overflow. For undissolved or dissolved slowly scale, has a certain power, make the scale from off heated surface of plate heat exchanger. 4) Osteoporosis: for with silicate and sulfate mixed scale, because of calcium, magnesium, carbonate and iron oxide dissolved in acid solution, the residue of scale will become loose and can easily be washed down flow of acid solution. 1, the choice of cleaning agent 2, selection of cleaning agent, is currently used in pickling, it including organic and inorganic acid. Organic acids are: oxalic acid, formic acid, etc. Mainly include: inorganic acid hydrochloric acid, nitric acid, etc.
