| 摘要 |
The invention relates to a unit comprising multiple elements, essentially characterised by the use of high-power cavitation/friction mixers which are used together with dispersants and oxidants in multiple steps in series, as well as including an increase in the prior temperature in a continuous process. The device is based on the heating of organic material and dividing same into fine particles by means of cavitation-dispersion and on the chemical oxidation of the cell membranes and walls, all in order to promote conditions for biodegradability. The final operation is the result of the joint action of multiple systems that combine physicochemical dispersion forces, chemical oxidants and temperature. This combination multiplies the effect and minimises reagent and power costs. The unit comprises two heating modules, measurement and control means, a cavitation-dispersion reactor (7), a membrane-rupture cavitation reactor (8), and a sterilisation reactor (9), as well as a controlled acidification reactor. The invention can be used to improve the biodegradability of material and, consequently, the final energy yield. |
