Circulating water softening system based on variable frequency pulse electric field and its realization method

Abstract

The invention discloses a circulating water softening system based on frequency conversion pulse electric field and its realization method, which includes a control box, an electrode module placed in a circulating water storage tank and a PC communication module, and a microcontroller module is arranged inside the control box , a signal processing and control module, a driver amplifier module, a current detection module, a main power supply module and an electrode voltage adjustment module, and a display module is arranged on the front panel outside the control box, and the display module is connected to the microcontroller module through a cable. In the present invention, the variable frequency range of the frequency-variable pulse electric field can cover the variation range of the bond energy of water molecules that are prone to scaling. While ensuring no scaling, the calcium and magnesium ions in the water are crystallized and separated to truly realize zero discharge.

Description

technical field [0001] The invention relates to a softening water system for industrial circulating water, which is a circulating water softening system based on a frequency conversion pulse electric field and a realization method thereof. Background technique [0002] The frequency conversion pulse electric field water softening device is mainly used to solve the water softening problem in chemical industry, printing and dyeing, boiler, power plant, central air conditioning and other circulating water devices; at present, the water softening method of industrial water mostly adopts the ion exchange softening method of sodium ion exchanger. [0003] The softening principle of the ion exchange method is to use two tanks to produce water alternately. When one tank produces water, the other tank is adjusted; when the water production tank produces water, the calcium and magnesium ions in the water are fully adsorbed on the resin, and the water produced is softened water. ;When ...

AI Technical Summary

Problems solved by technology

[0004] The main disadvantages of the ion exchange method: A. Higher production costs: resin and salt are used in the softening process, especially the amount of salt is large. A medium-sized enterprise needs at least hundreds of thousands of yuan per year for softening water, or even millions of dollars

B. Serious pollution: The wastewater discharged from the exchanger not only contains calcium and magnesium ions, but also has a considerable part of excess salt water, which causes serious pollution to the local soil and groundwater
