A method and device for the thermal material treatment and - conversion of coarse particles in periodically - transient vibration fire - reactors

摘要

The invention relates to a method and a device for thermal material treatment and / or material conversion in particular of coarse, granular raw materials in a pulsating hot gas flow with independently of each other, an adjustable frequency and amplitude of the speed oscillation or of the static pressure oscillation of the hot gas flow in a vertically arranged reaction chamber. At the upper end of the vertically arranged reaction chamber raw material particles can be introduced as a result of their shape, the mass and the density at the adjusted mean flow velocity of the hot gas flow from this not be transported pneumatically, but fall downward counter to the flow direction. During this settling time of about 1 – 10 seconds, the thermal treatment of the material to the desired product, the at the lower end of the reaction tube with the aid of a sluice system is removed from the reactor is.
