The invention relates to a constant-concentration electrolysis water saving control circuit. The circuit comprises a single-chip microcomputer, A / D converters, a crystal oscillator, a photoelectric coupler, buttons, a digital potentiometer, a field effect transistor, a relay and a loudspeaker. According to the constant-concentration electrolysis water saving control circuit of the invention, the internal comparator of the single-chip microcomputer is adopted to output difference between a set value and a detected value to the digital potentiometer; the digital potentiometer amplifies the concentration difference signal; the field effect transistor tracks the concentration difference signal and dynamically changes the magnitude of output current; the speed of the copper ion release of an copper electrode can be changed; the circuit is innovative in that copper ion concentration is automatically adjusted; and when input channels receive heat exchange temperature difference and temperature signals, the program of the single-chip microcomputer sends 4-to-20mA current through an analog channel or sends a high and low electric level to a heating relay through a switch driver so as to control a water draining pump valve, a water replenishing pump valve and a heater.
Description
technical field [0001] The invention relates to the field of electricity, in particular to electrolyzed water circuit technology, in particular to a constant concentration electrolyzed water-saving control circuit. Background technique [0002] It is currently known that the consumption of copper ions can inhibit the growth of bacteria and algae in circulating water. When the concentration of copper ions in circulating water is constant at 0.5mg / L, it can kill bacteria and algae most economically. The sources of copper ions include pharmaceuticals and electrolytic copper. The circuit boards in all electrolytic copper equipment on the market cannot receive copper ion concentration signals, nor can the electrolytic current be adjusted online, in real time, and remotely according to the concentration, thereby changing the precipitation speed of copper ions. The concentration of copper ions in circulating water is constant at 0.5 mg / L. [0003] It is currently known that the te...
