At present, the literature reports on electrochemical scale treatment technology and the understanding of the technical principles of the professional technicians are limited to the formation of scale precipitation after the combination of the scale ions in the cathode region and the alkalinity, so that the hardness in the water is reduced and cannot be The surface of the heat exchange equipment is fouled. From the perspective of controlling the hardness level, the electrochemical scale treatment technology is considered. In order to ensure that the surface of the heat exchanger is not fouled, the hardness level in the circulating cooling water needs to be controlled to a lower value. Based on this, the prior art solutions are all started from the viewpoint of reducing the hardness, and accordingly, equipment selection is performed for the circulating cooling water system.
The invention of the invention discloses a method for selecting an electrochemical descaling device for a circulating cooling water system, comprising: (1) knowing the hardness removal amount and the alkali removal amount per unit time of the electrochemical descaling standard device; 2) Obtain the amount of water evaporating per unit time and the amount of wind and splash water in the circulating cooling water system under different external temperature conditions; (3) Obtain the water quality parameters of the supplementary water of the circulating cooling water system; (4) Target the chloride ion Material, complete the system water balance calculation; (5), initially select n sets of electrochemical descaling equipment, calculate the hardness concentration and alkalinity concentration in the system; (6), use the scale index model to calculate the equilibrium state The fouling index; (7), the calculation until the scale index is the same as the corrosion scale equilibrium point, and finally determine the specific number of choices.
The invention comprehensively considers equipment selection from the two directions of hardness and alkalinity, and is more economical and practical than the prior art, and will surely promote and lead the development of the electrochemical circulating water treatment industry.
