An ozone disinfection water preparation machine with an automatic control system for water outlet concentration

Abstract

The invention discloses an ozone disinfection water preparation machine with a water outlet concentration automatic control system, which relates to the technical field of ozone disinfection. It includes the following steps: perform absolute value calculation on the sampled detector data and the set value of the system, when the data meets the system limit value, start the monitoring counter to record the corresponding data format, when the number of data reaches the number specified by the system , start the valve switching mechanism; when the valve is switched, if any data is outside the limit value, clear the monitoring counter and activate the error counter counting, if the error counter data is greater than the system setting value, enable the valve switching mechanism; When the counter data is less than the system setting value, and the sampling data meets the limit requirement, the error counter is cleared; the whole process is executed cyclically. The invention adds digital stepless control high-voltage power supply, and uses PID algorithm combined with multiple auxiliary algorithms to precisely control the outlet water concentration (accuracy <0.5ppm).

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...
