されている。 In particular, as shown in FIG. 4, the injection pipe 17 has a total length l longer than the total length L of the bumper B by about 10% on both ends. That is, the total length l of the injection tube 17 is: l=L+2×0.1L Further, the introduction tube 18 is connected to the plasma introduction port 17a formed approximately in the center of the injection tube 17, and the end thereof is connected to the plasma supply outside the main body 1. Equipment (not shown)
connected to. A large number of injection ports 19 are formed on the outer periphery of the injection pipe 17 on both sides of the introduction port, and the arrangement interval gradually decreases toward the end of the injection pipe 17, and the inner diameter gradually increases until near the tip. Each injection port 19 has one opening 19a that is inclined forward at a predetermined angle θ 1 (30 degrees in this embodiment) with respect to the vertical plane S, and one that opens in a direction that is inclined at a predetermined angle θ 2 (30 degrees in this embodiment) to the rear side.
19b which opens in the direction of inclination. Then, the injection port 1 tilts toward the front.
9a and injection ports 19b inclined toward the rear are alternately arranged. In addition, from the injection pipe 18, the discharge port 2
The number of injection ports 19 on the side, ie, the right side, is set to be 15% smaller than the number of injection ports 19 on the left side of the discharge port 2.

る。 From the above, the injection pipe 7 is
If plasma gas such as oxygen is introduced into the injection tube 1
7 is made longer than the total length of bumper B by 10% at both ends, and the injection port 19 is formed with an inclination of 30 degrees from front to back with respect to the vertical surface S12. The plasma gas is sprayed so as to wrap around the edges, and the plasma gas is also diffused throughout the containment chamber, activating the surfaces of the multiple bumpers B that are rotating and revolving within the containment room even more uniformly. be able to.
