Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.
[0018] The simple device for anaerobic biogas production provided by the present invention comprises a transparent plastic bottle 1 with a volume of 500ml and a rubber stopper 2 that is tightly matched to the opening of the plastic bottle 1. The bottle wall of the plastic bottle 1 is relatively thin and has good toughness; the rubber stopper 2 There is a through hole (not shown in the figure), and a glass tube 3 is set inside the through hole, and the glass tube 3 and the rubber stopper 2 are sealed and matched. The two open ends of the glass tube 3 are respectively arranged on the plastic bottle. 1 inside and outside the cavity, the open end of the glass tube 3 in the cavity of the plastic bottle 1 and the end of the rubber stopper 2 in the cavity of the plastic bottle 1 are set on the same horizont...

The invention discloses a simple device for anaerobically producing biogas. The device comprises a reaction vessel with an adjustable volume and a plug which is in seal fit with an opening of the reaction vessel, wherein the plug is provided with a through hole; a hard tube is sleeved in the through hole, the plug and the hard tube are in seal fit, and two opening ends of the hard tube are arranged inside and outside a cavity of the reaction vessel respectively; a hose is sleeved on the hard tube which is arranged outside the cavity of the reaction vessel; and the length of the hose is greater than that of the hard tube which is arranged outside the cavity of the reaction vessel. The device makes the low-cost evaluation of biogas production capacity of a large quantity of biomass samples such as straws and the like possible; and a method for discharging oxygen in the reaction is simple, and the cost is almost zero.
Description
technical field [0001] The invention relates to a simple device for anaerobic biogas production. Background technique [0002] Biomass energy is an important direction of future energy development. Among them, the energy based on biogas (biogas), that is, industrial methane, is gradually realizing large-scale development. Straw and waste organic matter are important components of biomass, and the difficulty of evaluating methods for their gas production capacity plays a key role in the screening of new materials and resources, as well as in the breeding of energy crops. At present, the use of anaerobic fermentation devices mainly focuses on the research on the gas production capacity of different substances and the optimization of biogas production technology. The research devices are generally 1000ml-5000ml, and the materials used are plastics (Bai Jierui, Li Yibing, Guo Ouyan, etc.. The structure ratio of manure stalks under different temperature conditions and the influ...
