Embodiment Construction

[0058] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0059] The sterilizing and disinfecting water manufacturing device adopted in this embodiment is as follows: figure 1shown. The mixer 3 is a pure pipeline member with three input ports and one output port. The three input ports are respectively used to receive: the tap water injected into the mixer through the solenoid valve 1, the sodium hypochlorite medicine tank 6 extracted by the sodium hypochlorite dosing pump 5 The sodium hypochlorite solution inside and the hydrochloric acid solution from the hydrochloric acid adjustment liquid medicine tank 8 extracted by the hydrochloric acid adjustment liquid dosing pump 7, the three form hypochlorous acid solution after mixing in the mixer 3. The mixer 3 injects the hypochlorous acid solution into the buffer tank 4 through the outlet. The buffer tank 4 is provided with a pH sensor 10 for measuring the ...

Abstract

The invention provides a sterilization and disinfection solution preparing device and a mixed liquor PH value regulating and controlling method and belongs to the field of disinfection methods or devices for objects. The method comprises the steps of: firstly obtaining a pH measurement value of a hypochlorous acid solution; calculating an input signal of a fuzzy controller by using the PH measurement value; inputting the obtained input signal into the fuzzy controller; generating a dosing pump frequency signal via the fuzzy controller and controlling the pump output of a hydrochloric acid solution to keep the PH value of the hypochlorous acid solution stable within a certain range. The method uses the fuzzy controller to control the whole production process, enables the output change curve of the pH value of the hypochlorous acid solution to approach the ideal level, overcomes the defects of nonlinearity and big time delay of conventional control methods and has favorable effectiveness and robustness. With the system and the method, the workload of managing staff is reduced, the working efficiency is increased and the objectives of unattended operation, safety and reliability are truly achieved.

Description

technical field [0001] The invention relates to a method and a device for disinfecting objects, in particular to a device for producing sterilizing and disinfecting water and a method for regulating and controlling the pH value of a mixed solution. Background technique [0002] At present, the preparation of hypochlorous acid solution is generally to respectively inject sodium hypochlorite solution and hydrochloric acid adjustment solution into a mixer through a dosing pump, and after the mixer uniformly mixes the two solutions with tap water, the hypochlorous acid solution can be obtained. The mixing process needs to keep the pH value of the mixed solution within a certain range. Now the disinfectant water production devices with hypochlorous acid as the main component on the market are large in size and low in automation, requiring specialized personnel to guard and operate them. It is a nonlinear and large time-lag system. Therefore, it is difficult to obtain an accurate...
