Definitions

  • the present patent disclosure concerns a method and device for treating water and use thereof.
  • Particular embodiments of the device are for reducing NO X emissions from a combustion chamber.
  • Other embodiments of the device are for producing antioxidative water, hydrogen, oxygen and/or mixtures of these.
  • NO X nitrogen oxides
  • Treating water by electrolysis devices has the problem of often requiring aggressive electrolytes, for instance comprising potassium hydroxide, and catalysts which are typically noble and/or rare metals such as platina and iridium.
  • a device for treating water comprising a housing; an inlet for receiving water arranged at a first end of the housing; an outlet for outputting the treated water arranged at a second end of the housing; and two or more electrodes arranged in the housing, the two or more electrodes comprising a first electrode and a second electrode arranged opposite the first electrode such that a space is formed between the first and second electrodes; wherein at least one of the first electrode and the second electrode comprise a hydrophilic surface arranged to be in contact with the water, wherein the first and the second electrodes are arranged electrically insulated from the housing.
  • EZ-water exclusion zone
  • the electrodes being hydrophilic have the effect of allowing the formation of so-called exclusion zone (EZ-) water.
  • EZ-water forms, for instance, on National (sulfonated tetrafluorethylene based fluoropolymer-copolymer) layers, Nafion being a hydrophilic material.
  • the name EZ-water follows from the structured nature of this phase and its tendency to exclude impurities such as particles.
  • EZ-water is accompanied by charge separation, EZ-water being negatively charged, while the water outside the EZ-water phase being positively charged.
  • H3O2 When the EZ-water is negatively charged, it may be described by the general chemical formula H3O2, having a net charge of -1 (see e g. Ch. 4, e g. Fig. 4. 10, of “The Fourth Phase of Water”).
  • the growth of EZ-water can be accelerated by radiant energy such as infrared radiation.
  • Another way to grow the EZ-water is by applying a potential, in particular a negative potential.
  • the EZ-water being electrically charged means that the water is conductive.
  • the water that is not part of the EZ-water has increased amounts of hydronium ions, and is thus also conductive.
  • the EZ-water excludes other ions and particles so those will also be in the remainder of the water not part of the EZ- water.
  • the device can use demineralized water or distilled water, which will become conductive by being present in the device.
  • the water needs no additives such as alkaline salts in order to increase conductivity.
  • EZ-water When the device is used before an air inlet of a combustion chamber, for instance, in this way there is no or less corrosion or fouling as there are no additives.
  • electrolytic species such as salts or minerals
  • the device When the device is used together with a combustion chamber, with a mixture of water and air being input into the device, and the output mixture of treated water and air being fed into the air inlet of the combustion chamber, the amount of NO X that is emitted is drastically reduced. Emission reductions of over 30% have been measured. This may be due to the EZ-water, being typically antioxidative, to react as a reducing agent with NO and NO2. Hydrogen produced in the device may further act as a reducing agent.
  • the inlet may be one or more inlets.
  • the device is configured such that the two or more electrodes have corresponding two or more polarities, wherein adjacent electrodes have opposite polarities. In this way, two sides of the electrodes are used and thus the surface area for treating the water is increased.
  • the electrodes may be made of steel, such as stainless steel.
  • the steel is preferably polished, such as to improve its hydrophilic properties.
  • One type of suitable steel is polished 316L stainless steel.
  • the steel is brushed, grinded and/or polished. The polishing is preferably done one-directionally. This increases the surface wetting by water on the steel. In other words, the hydrophilicity of the steel is increased.
