Description

Full-automatic ozone water maker

Technical Field

The invention relates to the technical field of water electrolysis equipment, in particular to a full-automatic ozone water manufacturing machine.

Background

The ozone water is manufactured by two methods of electric air shock and electrolytic water, the electric air shock method generates a large amount of ozone gas after one-time air shock, then the gas is dissolved into the water by means of gas mixing and the like to quickly obtain a large amount of ozone water with higher concentration, but the concentration of the ozone water cannot be monitored, so that the feedback effect is not achieved, and meanwhile, low-concentration or trace ozone water cannot be manufactured in real time. The electrolyzed water can be used to obtain oxidation products such as hydrogen peroxide, ozone, hypochlorous acid (residual chlorine in water), etc. People disinfect the water body and the surrounding environment through the oxidation products. The water electrolysis device usually only has one anode and one cathode or a plurality of electrode plates, but the electrode plates are mutually conducted and can be regarded as one electrode, so that the module is only switched on and off in two stages, and the concentration of the oxidation product can be controlled only by controlling the current between the anode and the cathode. The control of the oxide concentration in the electrolyzed water is necessary, and the required power is different due to different water use scenes, so that the existing ozone water electrolysis equipment has the following problems:

1. the concentration is not adjustable: the concentration of the oxide is too high in the existing electrolysis device due to the unadjustable concentration, so that the oxidation damage is generated to the surrounding environment; the concentration of the oxide is too low to achieve the disinfection effect at high flow; and when the flow is low, large current is adopted to heat and wear the electrode plates, so that the aging and scaling of the electrode plates are accelerated;

2. it is difficult to control the oxide concentration by adjusting the voltage and current of the electrolyzer: in the actual research and development process, because the current is in dynamic change all the time, even if the current is operated in a current constant-current mode, the slope of voltage to current is changed, and the slopes of scale, water flow speed and power supply fluctuation are also larger, so that relatively large current change is brought by slight voltage change, and the control of the oxide concentration by adjusting the voltage and the current of the electrolysis device is difficult. As the time of use increases, scaling between the electrodes can cause the oxide yield to decrease for the same current;

3. mounting and dismounting are irreversible: because inside fastening and waterproof have higher requirement, so inside most can be sealed with glue or adopt silica gel in the current electrolysis module, so can't not harm and disassemble, unpack apart moreover and will not recover.

4. The ozone concentration of the water discharged by the water electrolysis technology is uneven, the ozone concentration is relatively low at a large flow rate, and the ozone concentration is relatively high at a low flow rate. Ozone water with specific concentration can not be manufactured, ozone concentration feedback information is lacked, trace ozone water can not be manufactured, the ozone water can not be used as it is, and ozone gas leakage and nitrogen oxide harm exist.

Therefore, a fully automatic ozone water producing machine capable of stably electrolyzing and producing oxides with different concentrations is required.
