  • the gas containing ozone gas Ozone gas is generated from the raw material. For this reason, compared with the case where air or oxygen is generated in the raw material, it is possible to generate ozone gas having a higher concentration.
  • the gas in the gas circulation path A is in a so-called sealed state confined by the liquid stored in the gas-liquid separator 103 and the liquid in the gas-liquid mixer 102, it is affected by the water pressure. The compressed pressure state is obtained. For this reason, since it becomes possible to introduce a high-density gas into the ozone gas generator 101 or the gas-liquid mixer 102, a higher-concentration ozone gas based on the high-density gas is generated by the ozone gas generator 101, An efficient gas-liquid mixing effect based on high-density ozone gas can be obtained by the gas-liquid mixer 102, and it becomes possible to generate ozone liquid having a drastically high concentration.
  • the sealed state is used to mean not only a physically sealed space but also a space in which a gas is confined by a liquid.
  • the gas can be sealed in the gas circulation path A of the ozone liquid generator 100, the liquid is always expressed as a sealed state even if the liquid is led out from the liquid outlet 110 or the liquid circulation port 111.
  • the generated ozone gas is gas-liquid mixer 102, pipe c, gas-liquid separator 103, pipe a, ozone gas generator 101, pipe b, gas-liquid mixer 102, pipe c, gas-liquid separator 103,. It will cycle repeatedly in the order. As a result, the ozone gas generator 101 does not dissolve in water and circulates it based on the gas containing the gas-liquid separated ozone gas to generate ozone liquid. A liquid will be produced.
  • the ozone liquid separated by the gas-liquid separator 103 is led out from the liquid circulation port 111 provided below the gas-liquid separator 103, circulated through the pipe d, and again the gas-liquid mixer 102.
  • the liquid is circulated in the liquid circulation path B.
  • the gas-liquid separated ozone liquid is gas-liquid separator 103, pipe d, gas-liquid mixer 102, pipe c, gas-liquid separator 103, pipe d, gas-liquid mixer 102,. It will circulate repeatedly.
  • the ozone liquid stored in the gas-liquid separator 103 or the ozone liquid circulating in the liquid circulation path B is repeatedly circulated to the gas-liquid mixer 102, so that the mixing efficiency is improved and the higher Concentration ozone liquid will be produced.
  • the liquid introduced into the pipe d through the water supply port 114 does not flow back to the liquid circulation port 111 of the gas-liquid separator 103 but flows from the inlet 106 of the gas-liquid mixer 102 to the gas-liquid mixer 102. Will be introduced.
  • the ozone liquid stored in the gas-liquid separator 103 is led out from the liquid outlet 110 when it exceeds a certain water level. Note that the amount of ozone liquid stored can be adjusted by changing the height of the liquid outlet 110 provided in the gas-liquid separator 103.
