Abstract

The invention discloses an automated biogas dry fermentation device, belonging to the field of energy saving and environmental protection, and consisting of an outer barrel composting trough 2 and an inner barrel anaerobic fermentation trough 4, and the required conditions of the reaction is controlled by a ventilation control system 3 of the outer barrel composting trough 2 as well as an automatic temperature control system 8 and a liquid flow mixing system 1 which control fermentation materials in the inner barrel anaerobic fermentation trough 4. The device is characterized in that the materials can be automatically discharged from the outer barrel composting trough 2 to be fed into the inner barrel anaerobic fermentation trough 4, and in order to ensure the leak tightness of the device, the invention provides three sealing modes of annular rubber pad type sealing, annular water ring type sealing and annular water seal. The device can reduce the possibility of leading oxygen into the device because of the misoperation of workers, and has good biogas quality and biogas generation rate.

Description

Technical field:

[0001] The invention belongs to the field of energy conservation and environmental protection, and relates to a dry fermentation biogas device mainly used in a biogas fermentation project for processing organic wastes, in particular to the sealing and automation of the biogas device. Background technique:

[0002] Biogas technology has been widely used in my country in recent years. In biogas technology, the sealing of fermentation equipment has a great influence on the quality and rate of gas production. Whether the sealing is good is the key to measure the successful operation of biogas fermentation equipment. At the same time, under the premise of the current energy crisis, biogas technology is vigorously promoted, and the automation of biogas equipment is a key factor affecting the wide application of biogas technology.

[0003] As we all know, if the biogas fermentation device leaks air, if there is oxygen in the device, no or less gas will be produced,...
