AI Technical Summary

Technical Problem

Existing biogas power generation systems face complexity in managing biogas production, requiring intricate valve operations and sensor controls, especially in large-scale plants, which complicates the structure and stability of biogas generation.

Method used

A biogas power generation system with a simplified structure, featuring a biogas generator, a biogas power generation device, a digestive liquid storage tank, and a drain pipe that directs digestive liquid to the storage tank, while a liquid pool in the drain pipe blocks biogas passage, maintaining a constant internal pressure in the biogas generator.

Benefits of technology

This configuration stabilizes biogas production with a simpler system, preventing biogas from entering the digestive liquid storage tank and maintaining a consistent liquid level, thus ensuring stable biogas generation and reducing system complexity.

Abstract

To provide a biogas power generation system capable of stabilizing the amount of biogas generated, with a simple configuration.SOLUTION: The biogas power generation system comprises a biogas generation tank (5) for fermenting an organic material to generate biogas, a biogas power generator for generating power using the biogas generated in the biogas generation tank (5), a digestive liquid storage tank (6) for storing the digestive liquid discharged from the biogas generation tank (5), and a drain pipe (51) for guiding the digestive liquid discharged from the biogas generation tank (5) to the digestive liquid storage tank. A liquid reservoir for blocking the free passage of the biogas generated in the biogas generation tank (5) is provided in the drain pipe (51).SELECTED DRAWING: Figure 2
