发明名称 METODO PARA CO-QUEMAR DESECHOS PELIGROSOS EN HORNOS ROTATORIOS INDUSTRIALES
摘要 A method and apparatus for cofiring in a kiln hazardous organic waste in solid, pasty, greasy or sludge form by introducing the waste directly into the burning zone of an industrial rotary kiln (1) and burning the waste in the burning zone simultaneously with the product treated in the kiln, such as cement, lime or lightweight aggregate. Specifically disclosed are five exemplifying embodiments for introducing the waste directly into the burning zone of the kiln (1), i.e., (A) through a side opening in the kiln (Fig. 2), (B) ballistically (Fig. 3), (C) by pre-mixing with a powder or granular material and pneumatically injecting the non-sticky mixture (Fig. 4), (D) by shredding (39) steel drums (26) containing the waste and thereafter separating (33) the drum fragments (37, 44) and mixing (41, 45) the remaining waste with powder or granular material (40) (i.e. as in (C)) prior to the introduction of the waste into the burning zone (Fig. 6), and (E) by pregasification of the waste (Fig. 5).
