Abstract

The invention discloses intelligent organic solid waste subcritical water recycling complete equipment and an intelligent organic solid waste subcritical water recycling system, which are characterized by implementing by the following: (1) a step of selecting a heating device, in which a steam generator and a heating medium heater are selected intelligently as a heating device of main processing reaction kettles for saving energy; (2) a step of fully automatic control, in which the on-site control and remote monitoring and control of the whole set of equipment and the whole system can be realized by fully automatic control; (3) a step of preprocessing materials, in which organic solid waste to be processed is crushed and stored in a preprocessing device, auxiliary materials are added and the mixture is delivered to the main processing reaction kettles; and (4) a step of performing sequencing batch and column type reaction, in which the sequencing batch and column type process design of the feeding, heating, maintaining and discharging of each main processing reaction kettle is realized by using an intelligent control means and the plurality of groups of main processing reaction kettles which are connected in parallel. The equipment and the system are fully equipped and automatized, realize functions of remote signaling, remote measurement, remote regulation and remote control,and are energy-saving, efficient, arranged compactly, environmentally-friendly and safe.

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,...

AI Technical Summary

Problems solved by technology

The process needs to add acid for acidification, which has high requirements on container materials; the heating and pressurization systems are separated, resulting in increased equipment costs; and the heat treatment effect is poor, resulting in long reaction time and limited processing capacity; the process is lengthy, resulting in low automation and impracticability There are many pollution control points, resulting in poor working conditions

Among the features of the device described in Chinese Patent Application No. 200920050434.7, electric heating molten salt is mainly used to heat the reactor. This heating method is relatively slow for large reactors, with long reaction time and limited processing capacity.

Japanese Patent Publication Nos. 2008-246300, 2003-306825, and 2003-47409 all record similar garbage disposal devices, but all have the technical problems of long heating time, high cost, low degree of automation, and limited processing capacity.
