Generation equipment and generation method for non-electrolytic slightly-acidic hypochlorous acid water

Abstract

The invention discloses a generation equipment and generation method for non-electrolytic slightly-acidic hypochlorous acid water. The concentration of the slightly-acidic hypochlorous acid water can be lower than 200 ppm, especially be lower than 60 ppm; the pH value ranges from 6.20 to 6.80, the pH fluctuation range is controlled to be within plus or minus 0.05 at any value therebetween, and stable storage can be performed for 18 months. The generation equipment comprises at least one stage of purification device, a slightly-acidic hypochlorous acid water generation device, a control system and water supply ports. The purification device is used for purifying raw water from a raw water supply system. The slightly-acidic hypochlorous acid water generation device is located in the down stream of the purification device, and is provided with reaction devices, a water inlet and addition agent injection devices. The reaction devices are used for performing a quantum chemical reaction on addition agents and water from the purification device, and controlling H hydrated protons by stage to reach the stable saturated solubility of H ions, thereby processing into the slightly-acidic hypochlorous acid water with stable pH. The control system is electrically connected with the slightly-acidic hypochlorous acid water generation device, and is arranged to accurately control a whole generation process. The water outlets of the purification devices and the water outlet of the slightly-acidic hypochlorous acid water generation device are connected to the water supply ports through corresponding pipelines in a switchable way. The equipment can provide various functional water with different uses, and can switch water taking types according to user needs.

Problems solved by technology

[0004] Currently commercially available water purification equipment usually uses one or a few of sand filtration, carbon filtration, softening filtration, precision filtration, ultrafiltration, reverse osmosis filtration (RO filtration) as water treatment methods, and generally can only provide a certain A specific type of purified water, but cannot meet the needs of different water quality in different application environments

In addition, none of the currently commercially available water purification equipment can produce slightly acidic hypochlorous acid water

[0005] At present, there are many production equipment and methods of hypochlorous acid water in the world, but the control method for the safety (low concentration, stable pH) of the generated hypochlorous acid water has not been mentioned, and the food contact designated by the US FDA The concentration of hypochlorous acid water is not higher than 60ppm. Only low-concentration hypochlorous acid water can be used in large quantities in an environment with people. It is widely used in industries with high safety requirements such as medical treatment, food processing, and public health.
