Abstract

The invention discloses a double heat energy heating biogas system, which comprises a fermentation tank, a feeding device, a biogas purification device and a biogas residue treatment device. A stirrer device and a heating device are arranged in the fermentation tank; the heating device comprises a solar energy heating device and an auxiliary heat energy heating device; the auxiliary heat energy heating device is a bioenergy heating house or a fully enclosed boiler directly-heated type heating house; the feeding device comprises a blending tank and a sedimentation tank; the biogas residue treatment device comprises a biogas slurry afterheat conducting tank and a solid-liquid separator connected with a biological fertilizer making equipment; the side faces of the blending tank are provided with the sedimentation tank, the biogas slurry afterheat conducting tank and a grit chamber; the biogas purification device comprises a multifunctional automatic regulator and a purifier; and the multifunctional automatic regulator comprises a gas-water separator and a positive and negative pressure protector. The system has the advantages of high concentration, high temperature, high stirring rate, high gas production rate, high energy conservation, high cost performance, low tank body, low investment, low danger and low operating cost.

Description

technical field [0001] The present invention relates to a biogas project, in particular to a biogas system with dual thermal energy heating type, which is specifically suitable for realizing the six-high and four-low effects of the biogas project. "Six high" refers to high concentration, high temperature, high stirring rate, and high gas production. High efficiency, high energy saving and high cost performance, "four lows" refer to low tank body, low investment, low risk and low operating cost. Background technique [0002] At present, the large and medium-sized biogas projects in China all adopt the traditional USR or CSTR process, which not only has low concentration (TS 3%–5%), low temperature (10–25°C), and low gas production rate (unit volume production Gas rate is about 0.3–0.5m3 / m3·d), and there are problems such as high energy consumption, low efficiency, and abnormal operation in winter on key equipment, and the benefits of energy saving and emission reduction and c...
