Apparatus and method for generating oxidatively and thermally-enhanced treatment liquids

摘要

A cleaning system comprising a liquid source configured to provide a feed liquid at a first temperature, and an electrolysis cell configured to receive the feed liquid and to electrochemically activate the feed liquid to provide an electrochemically-activated liquid, wherein the electrochemical activation also heats the feed liquid such that the electrochemically-activated liquid is at an elevated temperature that is greater than the first temperature. The cleaning system also includes a dispenser configured to dispense the electrochemically-activated liquid.

1. A method for cleaning a surface, the method comprising:
providing a system having an electrolysis cell, an ultraviolet-radiation generator, a heating element, a dispenser, and a fluid line, wherein the electrolysis cell, the ultraviolet-radiation generator, the heating element, and the dispenser are located along the fluid line such that the heating element is disposed between the ultraviolet-radiation generator and the dispenser; pumping a feed liquid having a first temperature from a liquid source through the fluid line to the electrolysis cell; electrochemically activating and heating the feed liquid in the electrolysis cell to provide an electrochemically-activated liquid at an second temperature that is greater than the first temperature, and which comprises reactive oxidative species; passing the electrochemically-activated liquid from the electrolysis cell and through the ultraviolet-radiation generator; emitting ultraviolet radiation towards the electrochemically-activated liquid in the ultraviolet-radiation generator to generate an oxidatively-enhanced, electrochemically-activated liquid in which the reactive oxidative species are converted to radicals with increased oxidation potentials compared to the reactive oxidative species in the electrochemically-activated liquid; heating the oxidatively-enhanced, electrochemically-activated liquid with the heating element; dispensing the heated, oxidatively-enhanced, electrochemically-activated liquid from the dispenser to the surface; and cleaning the surface with the dispensed heated, oxidatively-enhanced, electrochemically-activated liquid.
