Ozone disinfectant fluid preparation machine with water outlet concentration automatic control system

Abstract

The invention discloses an ozone disinfectant fluid preparation machine with a water outlet concentration automatic control system, and relates to the technical field of ozone disinfection. The methodincludes the steps of performing absolute value calculation on sampled detector data and a set value of a system, when the data conforms to an amplitude limiting value of the system, turning on a monitoring counter to record the conforming data format, and when the number of pieces of data reaches the number of pieces of data specified by the system, turning on a valve switching mechanism; when avalve is switched, if the data is outside the amplitude limiting value, zero-clearing the monitoring counter and activating an error counter to count, and if the error counter data is greater than the system set value, turning on the valve switching mechanism; if the error counter data is less than the system set value, the sampled data conforming to the amplitude limiting requirement, and zero-clearing the error counter; and executing the entire process cyclically. According to the invention, a digital stepless control high voltage power supply is added, and the water outlet concentration iscontrolled precisely (precision (0.5 ppm) by using a PID algorithm combined with a plurality of auxiliary algorithms.

Description

technical field [0001] The invention relates to the technical field of ozone disinfection, in particular to an ozone disinfection water preparation machine with an automatic control system for water outlet concentration. Background technique [0002] The traditional ozone water production equipment adopts an open-loop structure (the equipment does not automatically adjust the concentration of the effluent, and can only manually change the power of the ozone power supply to roughly adjust the ozone concentration in the water) or a switch-type closed-loop control method (the adjustment method is too simple, with large overshoot and undershoot. Adjustment); the above control methods cannot achieve precise control of the concentration of ozone water; the traditional outlet concentration cannot reach the target when starting up, and can only be roughly close to the required target after running for a period of time. [0003] In summary, the present invention proposes an ozone dis...
