Patent JP-S54107892-A (JP)
Title: Ozonizer
Inventor: TANAKA MASAAKI
IPC: B01J19/08
Filed: 1978-02-13
Abstract: PURPOSE: To provide an ozonizer the O 3  generation efficiency of which is enhanced by putting a porous metal body into the discharge space between a grounded metal electrode and a high voltage electrode so that the space is narrowed to the utmost.  
     CONSTITUTION: Porous metal cylinder 14 such as wire net having many protrusions 14a along the inner and outer circumferences is put into the middle of circular discharge space 3 between grounded metal tube 2 and high voltage electrode tube 4. At this time, protrusions 14a are joined to the inner circumference of tube 2 and the outer circumference of tube 4 to hold cylinder 14 in space 3. Since cylinder 14 is electrically contacted to tube 2, they are at equal potential. When silent discharge 15 is generated between cylinder 14 and tube 4, the actual discharge space depends upon the height of protrusions 14a. Raw gas of the arrow separately flows into spaces 3a, 3b with cylinder 14 in-between, yet the currents diffuse and mix through the many pores of cylinder 14. Thus, cylinder 14 exerts little influence on O 3  generation concn. distribution and temp. distribution.
