Efficient methane production device

Abstract

The invention relates to an efficient methane production device which comprises a conveyable base seat and a rotatable methane production container which is placed on the base seat and provided with a rotary shaft and an opening, a methane chamber is formed by an inner cavity of the container, first double helical blades are disposed in the inner cavity and connected with an inner wall of the inner cavity, a helical revolving shaft of the first double helical blades is coaxial with the rotary shaft, the opening is connected with a blind flange which comprises a flange tube and an inner tube disposed in an inner cavity of the flange tube, second double helical blades naturally engaged with the first double helical blades are disposed between an inner wall surface of the flange tube and an outer wall surface of the inner tube in a connecting mode, a methane outlet tube which extends into the inner cavity is disposed in the inner tube in an inserted mode, a center shaft of the inner tube is coaxial with the rotary shaft, feed / discharge propellers which are coherent and lead to the opening from the bottom of the inner cavity are formed by the first double helical blades and the second double helical blades together, a lower portion of the inner tube extends into inner cavity biogas slurry, and flange plates are disposed at two ends of the flange tube. According to the efficient methane production device, clockwise rotation and anticlockwise rotation of the helical blades are adopted to achieve automatic feed and discharge, the device is conveyable, methane production is rapid, and efficiency is high.

Description

technical field [0001] The invention relates to a device for efficiently producing biogas, which belongs to the technical field of bionew energy. Background technique [0002] In today's world, conventional energy sources such as oil and coal are about to run out, and the energy prospect is worrying. The development of new energy has been urgently requested. Biogas, as a kind of bioenergy, is essentially a gas with methane as the main component released during the natural decomposition of organic matter such as human and animal manure. Rational use of biogas is not only positive for the beautification of the environment. And the biogas slurry and biogas residue formed after the decomposition is completed are excellent fertilizers. Its positive significance is self-evident. [0003] Traditional biogas digesters generally dig pits on the ground or build cement ponds according to local conditions to make acidification ponds, fermentation ponds and discharge ponds, and then ...
