Large-sized biogas fermentation device integrating fermentation and gas storage

Abstract

The invention relates to a large-sized biogas fermentation device integrating fermentation and gas storage, comprising a feed port, a liquid outlet port and a dreg discharge port. The large-sized biogas fermentation device integrating fermentation and gas storage is characterized by comprising a casing, a gas generation chamber installed in the casing and a gas storage floating cover sleeved outside the gas generation chamber, wherein a water layer is arranged between the casing and the gas generation chamber; the gas generation chamber is internally provided with a biogas stirring device; and the bottom part of the gas storage floating cover is provided with balancing weights. The invention has the following advantages of compact structure, small occupied space, and convenient operation, management and maintenance due to the integration of fermentation and gas storage, safe and reliable use, ensuring of gas generation amount in winter, improvement of gas generation amount due to complete fermentation of raw materials and large-scale industrial production for facilitating the popularization of biogas.

Description

Technical field: [0001] The invention belongs to a biogas device, in particular to a large-scale biogas fermentation device integrating fermentation and gas storage. Background technique: [0002] As a renewable energy source, biogas is not only clean, cheap, and hygienic, but also gradually shows its unique advantages in many aspects such as the development of ecological agriculture, environmental protection, and comprehensive utilization, and is highly valued by people. However, the existing biogas installations have the following defects: 1. It is necessary to connect equipment for purification and pressure regulation of the biogas between the biogas digester and the biogas burner, such as desulfurizers, pressure gauges, etc., and many pipeline accessories are required to install these equipment. , It takes up a lot of space, and it is not very convenient to operate, manage and maintain. 2. The pressure of biogas is unstable during use, which brings inconvenience to user...

AI Technical Summary

Problems solved by technology

However, the existing biogas installations have the following defects: 1. It is necessary to connect equipment for purification and pressure regulation of the biogas between the biogas digester and the biogas burner, such as desulfurizers, pressure gauges, etc., and many pipeline accessories are required to install these equipment. , takes up a lot of space, and is not very convenient to operate, manage and maintain

2. The pressure of biogas is unstable during use, which brings inconvenience to users

3. Low gas production, generally around 100 cubic meters

4. There is no heat preservation device in the fermentation tank, and the gas production rate in winter is lower

5. Due to the overall structure of concrete pouring, the construction efficiency is low, and industrialized large-scale manufacturing cannot be carried out, which seriously restricts the popularization and promotion of biogas
