Carbon dioxide control solenoid valves 89, 89 are provided in the middle of the pipes 86, 86. Further, an ozone generator 90 is built in the apparatus main body 12. As shown in FIG. 3, an air inlet 92A is formed on the side 91A of the box portion 91 of the ozone generator 90 in the front of FIG. 3, and the top surface 91B of the box portion 91 shown in FIG.
An air outlet 92B is formed on the back side. A dielectric 93 formed of a ceramic plate is provided upright at a position corresponding to the air inlet 92A inside the box portion 91. A positive electrode 93A is provided on one surface (the front side in FIG. 3) of the dielectric 93, and a negative electrode 93B is provided on the other surface (the rear side in FIG. 3). As shown in FIG. 1, an ozone generation power supply 94 is provided near the box section 91, and is connected to the plus electrode 93A and the minus electrode 93B. Therefore, in the ozone generator 90, a high-voltage high-purity ozone can be efficiently generated by causing a ceramic creeping discharge (corona discharge) by an electric high voltage (5000 V to 50000 V). The amount of generated ozone is proportional to the amount of supplied oxygen (the amount of air), but is also affected by the temperature and humidity. Therefore, it is preferable that the supplied oxygen (air) be dried at an appropriate temperature. Since a ceramic plate is used, the inside of the box portion 91 is easily dried, and the occurrence of dirt in the box portion 91 is reduced, the discharge is prevented from being in an arc state, and even when the gas density is high. Ozone generation can be stably continued. The box section 9
A blower 95 is disposed adjacent to the air blower 1, and the air sent from the blower 95 enters the box portion 91 via the air inlet 92 </ b> A and is decelerated, and is discharged by the ceramic surface discharge (corona discharge) of the dielectric 93.

Since the vehicle is decelerated due to stagnation, it is converted into ozone by the dielectric 93 and exits from the air outlet 92B. The ozone generated by the ozone generator 90 is sent from the air outlet 92B through the ozone pipe 96 to the spray nozzle 40.

Radial needle reason the needle electrodes were radially electrode 102A is 1 cm ³ during about 10 ¹⁹ and also said to electrons to be larger the ratio of collisions with electrons in order to more ionized gas molecules having that release This is because the tip of the electrode to be formed has a radial shape. In addition, the ratio of electrons ionizing gas molecules in one collision is proportional to the applied electric field, so that the voltage was set to a high voltage (5000 V to 50000 V). The radial needle electrode 102A determined the ionization efficiency of the conventional wire electrode, needle electrode, and the like based on the smoke elimination time. As a result, the radial needle electrode 102A reduced the smoke elimination time to one third or less of the wire electrode and 5% of the needle electrode. It can be reduced to less than 1 /. As shown in FIG. 4, a plurality of communication holes 101 </ b> C are formed through the mounting plate 101 so that negative ions can freely move in the cylindrical body 100 regardless of the mounting plate 101. .

The ammonium bicarbonate contained in No. 6 has an ammonium bicarbonate odor, but the component of the ammonium bicarbonate odor is ammonia NH ₃ . However, the strong oxidizing with ozone O ₃ for ozone is sprayed against the ammonia odor, marked with O ozone to NH ₃ is a chemical formula of ammonia, without ammonia NH ₃ by alter the structure As a result, the smell of ammonium bicarbonate can be eliminated, and there is no problem with the smell of ammonium bicarbonate that has been produced in conventional food bacteriostatic treatment devices. Ozone is O
To return to oxygen O ₂ . Further, electric ionic bonding by negative ions also acts. Therefore, ammonium bicarbonate is rapidly neutralized by the combination of three kinds such as ozone, and when exhausted from the apparatus main body 12, returns to oxygen below the allowable concentration.
