Novel cylinder unpowered automatic mixing anaerobic fermentation reactor

Abstract

The invention relates to a novel cylinder unpowered automatic mixing anaerobic fermentation reactor. The anaerobic fermentation reactor comprises a reaction body outer cylinder and a reaction body inner cylinder, a flange is arranged at the top of the reaction body outer cylinder, and the anaerobic fermentation reactor is characterize in that a feed pipe and a gas guide pipe are arranged in the reaction body inner cylinder, a gas inlet pipe communicated with the gas guide pipe is arranged on the flange; the upper part of the reaction body outer cylinder is provided with a discharge outlet communicated with the external, a gas outlet communicated with the cavity between the reaction body outer cylinder and the reaction body inner cylinder is arranged on the flange, and a U-shaped tube having an upward opening and used for communicating the inside of the reaction body inner cylinder with the external cavity is arranged on the reaction body inner cylinder. According to the anaerobic fermentation reactor disclosed by the invention, by virtue of the gas guiding effect of the U-shaped pipe, the periodic stirring of the fermentation substrate is achieved, the structure is simple, the electric energy is not needed to maintain the reaction and thus the unpowered stirring reactor is of great significance for being applied in the poor and underdeveloped countries and regions.

Description

technical field [0001] The present invention relates to a new cylinder unpowered automatic agitation anaerobic fermentation reactor, more specifically, it relates to a new cylinder unpowered automatic agitation anaerobic reactor which relies on the gas produced by substrate fermentation to push the liquid level to change to achieve stirring fermentation reactor. Background technique [0002] With the continuous development of the world's science and technology economy, limited resources are rapidly consumed, and environmental problems are becoming increasingly prominent. In particular, the global warming effect is a serious threat to human existence. Anaerobic fermentation technology can convert organic matter into methane and other energy gases while processing waste or other solid substrates. While improving the environment, it reduces the emission of greenhouse gases, so it has huge social benefits. [0003] However, anaerobic fermentation on solid substrates often exh...
