1. A high frequency tubular ozonizer comprising a hollow housing, at least one ozonizing element accommodated in said housing, said ozonizing element including a low voltage tubular electrode formed by two coaxial disposed pipes and adapted to be cooled by a flowing liquid, the output pipe forming a cooling jacket with said housing and adapted to render the flow of the cooling liquid turbulent and increasing the intensity of cooling of said low voltage electrode, and a high voltage tubular electrode coaxially arranged inside the low voltage tubular electrodes in the form of a pipe of a varying cross-section having a middle expanded portion, a flange at one end thereof and a thread at the other end thereof and a core for rendering turbulent the flow of the cooling liquid and increasing the intensity of cooling of said high voltage electrode disposed in the middle expanded portion of the high voltage electrode;

  • the opposing surfaces of the pipes of the low voltage and the high voltage electrodes forming a discharge zone, at least one of the surfaces of said pipes being coated with a layer of dielectric, two manifolds forming the butt ends of said housing and adapted for supplying and discharging, respectively, the cooling liquid to and from said high voltage electrode, at least two insulating, cup-shaped centering bushings having openings in the walls and bottom thereof disposed on the ends of the pipe of said high voltage electrodes and centering said high voltage electrode inside said low voltage electrode, branch pipe means for supplying cooling liquid to said low voltage electrode installed on the housing, two diaphragms arranged in parallel and installed between said housing and said outer pipe of said low voltage electrode, said outer pipe having an opening in the interval between said diaphragms, the space formed by said diaphragms opposite said branch pipe and from which space cooling liquid flows to the water jacket of said low voltage electrode, branch pipe means for discharging said cooling liquid from said low voltage electrode on said housing, two diaphragms arranged in parallel and installed between said housing and said outer pipe of the low voltage electrode, said outer pipe having an opening in the interspace between said diaphragms which form a space located opposite the second mentioned branch pipe, the cooling liquid from said water jacket being discharged from the ozonizer via said second mentioned branch pipe two annular, insulating bushings disposed respectively between each of said manifolds and the butt ends of said housing and along the perimeter thereof, said bushings, said butt ends and said manifolds in combination forming two spaces, the gas to be ozonized being fed from one of said spaces via an opening in one of said centering bushings to the discharge zone of each ozonizing element and the ozonized gas flowing to the other of said spaces from said discharge zones and from the ozonizer through said second mentioned branch pipe.
