METHOD FOR LIQUIDS DISINFECTION AND HEATING, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC A61L2/12 F24C7/02 C02F1/48 A23L2/48 A23L3/32 

FIELD: chemistry.

SUBSTANCE: method of water disinfection and heating includes the effect of microwave energy on the processed water flow of a given size, passing through a rectangular waveguide at an angle to its wide wall. An aqueous solution of ionic silver is added to the flow based on its concentration in the treated water of 0.01-0.02 mg/l. Water is passed through a device including a microwave generator, a rectangular waveguide with flanges, a radiating transparent tube passing through it, the axis of which is at an angle to the wide wall of the waveguide, and an end matched absorbing load. The tube through which the flow is passed has an expanding shape. The width W has a maximum value of 0.66 of the waveguide wide wall size, the height h at the waveguide entrance is 0.06-0.15 of the wavelength, and the height H at the waveguide output is 0.18-0.47 of the wavelength and is set wide side to the direction of electromagnetic wave propagation.

EFFECT: decreased liquid disinfection temperature, increased efficiency of microwave energy absorption and productivity, reduced energy costs, accelerated process of microwave disinfection and water heating, a possibility of using of a lower dose of ionic silver.
