AI Technical Summary

⚠Technical Problem

Existing systems face challenges in reducing the amount of sludge generated from anaerobic digestion and improving biogas production efficiency while managing high energy consumption and operational pressures.

⚗Method used

A system integrating a hydrothermal carbonization apparatus with a preheating tank, multiple reactors, a vacuum tank, steam purification, and a heat exchanger, along with a control unit, to optimize the hydrothermal carbonization process, reuse thermal energy, and reduce energy consumption by recycling gaseous components.

🎯Benefits of technology

The system effectively reduces sludge volume, increases biogas production by 20%, and minimizes energy consumption by recycling thermal energy within the system, thereby improving overall efficiency and reducing the impact on downstream processing.

Abstract

A system for reducing organic waste and increasing biogas production combined with a hydrothermal carbonization device with improved energy consumption efficiency is disclosed. According to one aspect of the present invention, the system for reducing organic waste and increasing biogas production includes: a storage tank for receiving and storing organic waste; an anaerobic digestion tank for receiving the organic waste from the storage tank to digest the organic matter and produce biogas; a dehydrator for primary dehydration of the organic waste discharged from the anaerobic digestion tank; a hydrothermal carbonization device for receiving the dehydrated organic waste and hydrothermal carbonization; and a filter press for secondary dehydration of the hydrothermal carbonization product discharged from the hydrothermal carbonization device.
