1. A device for the treatment of a charged hot gas comprising a cooling and/or quenching vessel having a gas inlet and a gas discharge,
wherein:
a first quenching chamber and a second quenching chamber are formed in said cooling and/or quenching vessel,the first quenching chamber is arranged in the upper part of the cooling and/or quenching vessel in the area of the gas inlet and has a diameter which is approximately 1.05 to 5 times that of an inside diameter of the gas inlet and a length which is approximately 0.5 to 5 times that of the inside diameter of the gas inlet,one or more nozzle rings comprising nozzles are arranged in the lower area of the first quenching chamber which are designed in such a way that 1 to 30 nozzles are available per 10,000 m3 of hot gas in the standard state, dry (i.s.dr.), andthe nozzles are configured in such a way that a quenching liquid issues at a downward angle of −30° to an upward angle of 5° in a quantity of 5 to 50 m3 per 10,000 m3 of hot gas in the standard state, dry, with a nozzle discharge rate of 2 to 30 m/s and with a droplet spectrum of 100-3,000 μm.
