Abstract:
1. A self-propagating combustion cyclone reactor, comprising: an enclosure; a lining arranged inside the enclosure and enclosed by the enclosure, the lining forming a hollow chamber and having upper and lower ends forming a gas outlet and a product outlet respectively; at least one reductant inlet formed in a circumferential wall of the chamber in a tangential manner and communicating an upper portion of the chamber for receiving a reductant and a pressurized gas to supply the reductant into the chamber along a tangential line of the reductant inlet in a pressurized manner to thereby impinge on an inside surface of the circumferential wall of the chamber to induce a first cyclone; a plurality of oxidizer inlets formed in the circumferential wall of the chamber in a tangential manner and communicating the upper portion of the chamber for respectively receiving oxidizer, the oxidizer being supplied into the chamber along tangential lines of the oxidizer inlets in a pressurized manner to thereby impinge on the inside surface of the circumferential wall of the chamber to induce a plurality of cyclones, whereby, inside the chamber, the oxidizer collides the reductant fed through the reductant inlet to induce self-propagating combustion reaction and thus generating primary product and by-product, the primary product being discharged through the product outlet formed at the lower end of the chamber; a drive rod extending through the lower end of the lining into the chamber, the drive rod being movable upward/downward with respect to the chamber, the drive rod being a hollow member defining a channel extending therethrough, a conic regulation member being mounted to an inner end of the drive rod that is located inside the chamber that is spaced from the inside surface of the chamber by a gap, the gap being adjustable by the movement of the drive rod with respect to the chamber, the drive rod having an outer end located outside the enclosure and forming a by-product outlet in communication with the channel for discharging the by-product of the reaction between the reductant that is supplied through the reductant inlet and the oxidizer that is supplied through the oxidizer inlets; a first control valve mounted to the drive rod to control closing/opening of the channel defined in the drive rod; a second control valve mounted to the gas outlet in the upper end of the chamber to control closing/opening of the gas outlet; a third control valve mounted to the product outlet in the lower end of the chamber to control closing/opening of the product outlet; and a plurality heaters arranged around a lower portion of the lining and the product outlet to facilitate heating to the lining and the product outlet.
