A pH probe 13 is installed inside the box 10, and the pH probe 13 is electrically connected to the output end of the PLC controller 14. A differential pressure gauge 6 is installed on the side of the tank body 2, and the differential pressure gauge 6 is electrically connected to the output end of the PLC controller 14. A thermometer 5 is installed on the top of the tank body 2, and the thermometer 5 is electrically connected to the output end of the PLC controller 14.

At the same time, each component is controlled by the PLC controller 14 to replace manual control and achieve the purpose of automatically monitoring and adjusting the process technology, so as to avoid the delay effect of manual control and improve the accuracy and timeliness of the operation.

[0020] On the basis of the above scheme, the circulating air component includes a fan unit 3 and a pipeline 4.

[0021] It should be noted that the utility model is a fully automatic Venturi control system. The pH probe 13 monitors the circulating water reagent concentration in real time, and adjusts the working reagent input of the diaphragm pump 7 in real time through PID control and circulating water flow. The flow meter 9 also monitors the operating status of the water pump 11. When a fault occurs or there is no flow, it will stop running, and the PLC will issue a fault alarm. The differential pressure meter 6 monitors the wind pressure status and filter blockage in real time, and uses PID to control the circulating fan speed to adjust the circulating air volume. When the wind pressure value is lower than the set value, the fan speed is increased to increase the air volume. When the fan reaches the working frequency, the PLC issues a command to replace the filter.
