Description

technical field

[0001] The invention relates to a method and device for treating and reusing organic solid waste, in particular to a complete set of intelligent organic solid waste subcritical water resource treatment equipment and system. Background technique

[0002] Subcritical water refers to compressed liquid water with a temperature between 180°C and 350°C. [H in subcritical water 3 o + ] and [OH - ] is close to weak acid or weak base, so it has the functions of acid catalysis and base catalysis; subcritical water has a sufficiently small dielectric constant, and has the characteristics of dissolving organic and inorganic substances at the same time; at the same time, subcritical water also has excellent mass transfer performance and green advantages. The use of subcritical water technology can decompose cellulose, starch, higher fatty acids, and some plastics in garbage, so that macromolecules can be transformed into other organic products such as small molecules,...

Examples

Embodiment 1

[0040] Using 2 sets of 3m 3 The sequential batch reactor is heated by a steam generator (standard steam volume 2t, 2MPa), and processes 5 tons of kitchen waste and 6 tons of plant fertilizer. According to the test data, the material reaction batch processing time is about 10 minutes for input time, 10 minutes for heating time, 30 minutes for holding time, and 10 minutes for discharge time. Input to intelligent control panel 12 accord with figure 2 The control program required by the process; all materials are crushed by the crusher 1 and stored in the storage box 2 for about 13m 3 ; The intelligent console 12 controls the screw conveyor 3 to convey the material to the main treatment reactor 4A, and fills up after about 10 minutes; the intelligent console 12 controls the steam generator 10 to start heating the main treatment reactor 4A; after about 10 minutes, When the pressure sensor 4A1 and temperature sensor 4A2 reach the specified value (1.8MPa, 200°C), the intelligent c...
