FOR COOLING WATER
FOR PROCESS LINE
CASE:MILK OF LIME
Various ion, such as calcium, magnesium, and silica, has melted into well water and industrial water which are used for cooling water. Those ion becomes entwined intricately and has become a scale ingredient.
On the other side, pipes, such as vinyl chloride, iron, and stainless steel, have a negative electric charge.
For that reason, a scale ingredient with a positive electric charge adheres little by little electrically, and the grown-up thing is a scale.
The substances which become a scale easily are mainly calcium carbonate and silica. These have reverse character, respectively.
By a high temperature and high pH, calcium carbonate becomes difficult to melt and precipitates. Conversely, silica melts easily.
Usually, cooling water becomes an alkali tendency, and also that becomes a high temperature in a heat-exchange part.
From these things, it is generally mentioned that cooling water tends to generate the scaleproblem by calcium carbonate.
THE FUNCTION OF DIGISAVIOR
DIGISAVIOR makes a pulsing motion of wide range electromagnetic waves with modulation frequency technique.
The factor of the scale is constituted by various impurities. When irradiated with electromagnetic waves, the electronic state of all these substances are affected.
By the electromagnetic waves of DIGISAVIOR, as for some, electron transition happen, some are disassembled, and some become colloids.
It is neutralized, or the impurities which caused the change to the ionic state raise surfacepotentia
l, and have electric repulsion. For that reason, that does not become a scale.
Moreover, that removes the scale already attached.
DIGISAVIOR brings a greatest effect to the liquid solution of pH neutral-strong alkali.
DIGISAVIOR removes and prevents the scale of cooling water and the strong alkali water for processes surely.
ENERGY SAVING BY SCALE REMOVAL
When scale or slime adheres to heat exchanger even with less than 0.8 mm thickness, the energy consumption will increase more than 20%.
For example, if you remove the scale attached to the turbo refrigerating machine of 130kW(200RT), US$10,000- can be saved annually.
