How to deal with plate heat exchanger scale

  During the use of the plate heat exchanger, the water quality is not up to standard due to improper operation of the water treatment equipment. How to deal with plate heat exchanger scaleThe unqualified softened water is injected into the heating system, so that the calcium, magnesium and carbonate in the water are decomposed into calcium carbonate when heated. And the calcium hydroxide precipitate is formed on the heating surface of the heat exchanger to form a hard scale. Three methods for dealing with the scale of the plate heat exchanger

 (1)Dosing softening treatment

The method is simple, high in efficiency, economical, and does not require special water-making equipment, which is a highly practical anti-scaling water treatment method. According to different methods of dosing, there are two kinds of calibrator treatment and anti-scaling treatment.

(2)Magnetized anti-scaling treatment

After the water flows through the high-intensity magnetic field, the multi-molecular association and the ionic magnetic field in the water, the original multi-ionic association of the ions is broken up into a single or short-bond associationThey cut the magnetic field lines of the external magnetic field vertically at a certain speed to generate an induced current. Therefore, each ion establishes a new magnetic field in the same direction as the external magnetic field, and adjacent ion molecules with polarity are sequentially compressed and attracted to each other, resulting in a change in crystallization conditions, and the formed crystals are slack and resistant. It has poor pressure and tensile strength, and is very brittle. Its adhesion and adhesion are also weak. They are not easy to adhere to the heated surface to form scale.

3, Ion bar anti-scale water treatment

This method is an emerging and advanced water treatment equipment, which has a good application effect in central air conditioning systems, hot water circulation systems and circulating cooling water systems.
