れることである。The Swedish Patent Application No. 8310/722-5 describes a method and a device for replacing the plasma generator during continuous operation of a vertical furnace reactor. The replacement operation is accomplished via a valve device mounted on the reactor wall connected to the reactor tuyere. This valve arrangement completely hermetically isolates the relevant actor from its external atmosphere when the plasma generator is removed, and can only be used when the plasma generator is in the sealed state. That is, in this case, the nose section for connecting the plasma generator is fitted into the connecting section of the reactor tuyere. The disadvantage of the above-mentioned method is that a gap is created between the reactor siding and the plasma generator nose during the valve opening period when the plasma generator is moved from the sealed position to the operating position. This means that leakage occurs from the inside. This leakage effect can be suppressed to a minimum by tightly fitting the periphery of the four parts of the plasma generator into the opening at the connection part of the tuyere. This therefore reduces some leakage effects. However, this has the disadvantage that not only the production cost increases, but also the insertion and coupling configuration of the plasma generator becomes complicated.The purpose of the present invention is to prevent leakage during the insertion of the combustor into a reactor during operation. The objective is to provide an effective sealing device that can be significantly reduced. In particular, during the suction period when the plasma generator is inserted from the closed position when the valve device that completely seals off the reactor from the external atmosphere is placed in the open position, the plasma generator operates to seal the sealed surface of the reactor. The leakage effect is prevented until it is inserted into position.

It is characterized in that it is constituted by a sealing ring arranged as a separate seating member. The sealing ring has multiple openings distributed around the ring for connection to a source of safety gas. Is it the same as the gas pressure inside the reactor?
By using all the pressurized gas, gas leakage from inside the reactor can be reliably prevented. It can be held. This also makes the insertion and connection operations of the reactor significantly easier and faster.

に制限することが可能である。As shown in the double series of ``Effects of the Invention'', when the sealing device according to the present invention is connected to a TIH plasma generator, leakage from the reactor is completely prevented, but the above-mentioned effect of introducing the safety gas is limited. This gas is then allowed to flow into the reactor row. However, gas inflow into the reactor can be limited to a minimum by carefully adjusting the pressure of the safety gas so that the pressure and build-up within the reactor is negligible.
