摘要:
A plasma generator (1) comprises: a liquid containing part (3) which contains a liquid (6) including water; a gas containing part (4) which contains a gas; and a partition wall part (5) that separates the liquid containing part and the gas containing part from each other and is provided with a gas passage (5a) through which the gas in the gas containing part is led to the liquid containing part. The plasma generator (1) is also provided with a first electrode (10) that is arranged in the gas containing part and a second electrode (11) that is arranged so as to be in contact with the liquid in the liquid containing part. The plasma generator (1) is further provided with: a gas supply unit (9) which supplies the gas to the gas containing part; a plasma power supply unit (13); and a projected part (14) which serves as a drainage promotion part that prevents the liquid from remaining in the gas passage after the liquid in the liquid containing part is drained.

摘要:
A cleaning and purifying apparatus 40 cleans a cleaning object 51 in cleaning liquid generated by a plasma generator 1 and pours liquid from a water injection portion 60 toward the cleaning object 51 at the end of cleaning.
摘要:
A plasma generator 1 includes a first electrode 12 provided in a gas storage section 5; and a second electrode 13 separated from the first electrode 12 and provided in a manner such that at least the portion coupled with the first electrode 12 is in contact with a liquid 17 in a liquid storage section 4. Electric discharge is caused between the first electrode 12 and the second electrode 13 so as to produce plasma in a gas region in the liquid 17 in the liquid storage section and produce hydroxyl radical from water contained in the liquid 17 and oxygen contained in the gas. A voltage controller 60 controls a voltage applied by a plasma power source 15 depending on conditions.

A plasma generator 1 includes: a liquid storage section 4 that stores a liquid containing water; a gas storage section 5 that stores a gas; a partition 3 provided with a gas passage 3a to introduce the gas in the gas storage section 5 into the liquid storage section 4 and separating the liquid storage section 4 from the gas storage section 5; a first electrode 12 provided in the gas storage section 5; and a second electrode 13 separated from the first electrode 12 and provided in a manner such that at least the portion coupled with the first electrode 12 is in contact with the liquid in the liquid storage section 4. A predetermined voltage is applied between the first electrode 12 and the second electrode 13 while the second electrode 13 is grounded.

A plasma generator 1 includes a first electrode 12 provided in a gas storage section 5, and a second electrode 13 provided in such a manner that at least a portion coupled with the first electrode 12 comes into contact with a liquid 17 in a liquid storage section 4. Electrical discharge is caused between the first electrode 12 and the second electrode 13 so that plasma is produced in a gas region in the liquid 17 in the liquid storage section 4, and hydroxyl radical is produced from water contained in the liquid 17 and oxygen contained in the gas.
