US 10,029,928 B2 · Device for manufacturing sodium hypochlorite or hypochlorous acid and water treatment system in general

Abstract

This disclosure includes a device for producing sodium hypochlorite or hypochlorous acid for water treatment, the device including: a cylinder for storing salt in solid form, adapted for being fed directly via a pressurized water pipe, and including one or more tubes that form one or more electrolytic chambers; one or more electrolytic cells received in the electrolytic chambers; the tubes of the cylinders being perforated to allow the contacting of the electrolytic cells with the salt-saturated water while preventing the electrolytic cells from being short-circuited by the solid salt. This produces sodium hypochlorite or hypochlorous acid from salt-saturated water in a cylinder, connected directly to the pipe of the water to be treated without the latter being loaded with salt.

Dependent claims

A device for producing sodium hypochlorite or hypochlorous acid by electrolysis of NaCl salt-saturated water, the device being suitable for being connected directly on a pipeline of water to be treated under pressure of a water treatment system, the device comprising:

a cylinder storing salt in solid form, the cylinder being suitable for being supplied directly by the pipeline of water to be treated under pressure to form the NaCl salt-saturated water, the cylinder comprising more than one tube;
wherein each of the tubes forms an electrolysis chamber adapted for generating sodium hypochlorite or hypochlorous acid by electrolysis of the NaCl salt-saturated water;
wherein an electrolytic cell provided with electrodes is inserted into each of the electrolysis chambers;
and
wherein each of the tubes is perforated so as to enable the corresponding electrolytic cell to be in contact with the NaCl salt-saturated water to be electrolyzed, and to prevent NaCl salt in solid from coming into contact with the electrodes of the electrolytic cell.
