Definitions

  • FIG 1 shows a side view of an electrolytic chlorinator 10 for a swimming pool or spa.
  • the electrolytic chlorinator 10 includes a housing 20 and an electrolytic cartridge 30.
  • the housing 20 is substantially cylindrical in shape and has an open end 21.
  • a housing thread 22 is located on the outside of the housing
  • the electrolytic cartridge 30 includes a cartridge body 31 that substantially surrounds a series of electrodes in the form of an anode assembly 50 and a cathode assembly 60 shown in more detail in FIGS. 2 and 3.
  • the anode assembly 50 includes four mesh anode plates 51 having the dimensions of 1.0 x 50 x 200 mm.
  • the four mesh anode plates 51 are electrically connected to each other via an anode busbar 52.
  • An anode electrical connection assembly 53 is welded to an outer mesh anode plate located adjacent the end cap 40.
  • the anode electrical connection assembly includes an L-shaped bar 54 welded to an electrode bolt 55.
  • the L-shaped bar 54 is welded to an inner side of an outer mesh anode plate.
  • the cathode assembly 60 includes three flat cathode plates 61 having the dimensions of 0.5 x 50 x 210 mm.
  • the three flat cathode plates 61 are electrically connected to each other by a cathode busbar 62.
  • a cathode electrical connection assembly 63 is connected to an outer flat cathode plate.
  • the cathode electrical connection assembly 63 includes an L-shaped bar 64 welded to an electrode bolt 65.
  • a titanium nut 66 and grommet seal 67 is located on the electrode bolt 65.
  • the electrode bolt 65 extends through the end cap 40 and is used to electrically charge the cathode.
  • Each of the flat cathode plates 51 is made from a nickel, chrome, molybdenum alloy with the proprietary name of "Hastelloy C-276". However, it should be appreciated that other types of nickel alloys and also austenitic steels may be used to produce the flat cathode plates.
  • Each of the flat cathode plates 51 are electro polished to less than Ra 0.1 micron to minimise the deviations, pits and/or imperfections. That is, the electro polishing of the flat cathode plates increases the smoothness of the flat cathode plates.
  • the anode plates 51 and cathode plates 61 are located within the cartridge body 31.
  • the cartridge body 31 is formed from an upper part 32 and a lower part 33 that are joined together.
  • Each of the upper part 32 and lower part 33 has a series of longitudinally extending grooves (not shown).
  • the cathode plates 61 and anode plates 51 are located within respective grooves and are sandwiched between the upper part 32 and the lower part 33 to hold them in position.
  • the upper part 32 and the lower part 33 are ultrasonically welded together to hold the cathode plates 61 and anode plates 51.
  • a longitudinal channel 34 is formed within the cartridge body 31 to allow for the passage of water through the housing 20.
  • a roof 35 of the upper part 32 of the cartridge body 31 is curved and has the same diameter as the inside of the housing 20.
  • a series of fins 36 extend around the cartridge body 31 and are also curved and have the same diameter as the inside of the housing 20.
  • the electrolytic cartridge 30 can be removed from the housing 20 by unscrewing the sealing ring 42 from the housing 20, removing the end cap 40 from the open end 21 of the housing 20 and then sliding the electrolytic cartridge 30 out of the open end 21 of the housing 20. This enables the electrolytic cartridge 30 to be replaced or cleaned easily.
  • the fins 36 (in conjunction with the roof) seal the housing 20 between the inlet 23 and the outlet 24.
  • the water can only pass from the inlet 23 to the outlet 24 through the channel 34 formed within the cartridge body 31.
  • a current is applied to the electrode bolt to produce electrolysis using the cathode and anode to cause chlorine to be released into the water in a manner that is well known in the art.
  • the polarizing voltage is applied when using reverse polarity i.e., a reversal of microamps/m2.
  • the electrolytic chlorinator 10 provides the distinct advantage of reduced cleaning frequency. This is due to the polishing of the cathode, the cathode being a flat plate and the increased velocity of the water across the cathode. This reduces the build up of scale (such as calcium carbonate or calcium hydroxide or magnesium hydroxide) on the cathode plates 61 and hence cleaning can be performed less frequently.
  • scale such as calcium carbonate or calcium hydroxide or magnesium hydroxide
