Agricultural ecological system energy circulatory system

Abstract

The invention provides an agricultural ecological system energy circulatory system, which comprises a crop planting system and a livestock breeding system. The livestock breeding system comprises a livestock breeding farm, a biogas preparation device and a biogas collector, a generator is connected with the biogas collector by a pipeline, a solid and liquid separation device is connected with thebiogas preparation device, biogas slurry separated by the solid and liquid separation device can be used as a water flush fertilizer for vegetables, seedlings and fruit trees, biogas residues can be used as organic fertilizers for seedlings and fruit trees, the biogas preparation device comprises a biogas fermentation pool, a gas outlet, a material inlet and a waste discharge outlet are formed inthe biogas fermentation pool, an automatic door is arranged on the waste discharge outlet, a heat-insulation wall is arranged on the periphery of the biogas fermentation pool, and a biogas slurry outlet and a biogas residue outlet are formed in the heat-insulation wall. The agricultural ecological system energy circulatory system has the advantages that plant planting, livestock breeding and the biogas fermentation pool are implemented with one another and are matched with one another, accordingly, resources can be reasonably configured and utilized, and the methane tank is heated by waste heat of biogas waste material in winter to solve the insulation problem of the methane tank with teh lowest energy consumption.

Description

technical field [0001] The invention belongs to the field of ecological agriculture, in particular to an agricultural ecological system energy cycle system. Background technique [0002] Ecological agriculture is an agricultural ecological economic complex system, which integrates the agricultural ecological system and the agricultural economic system in order to obtain the greatest overall ecological and economic benefits. It is also a large-scale agriculture that integrates agriculture, forestry, animal husbandry, sideline and fishery industries, and a modern agriculture that integrates agricultural production, processing, and sales to adapt to the development of a market economy. There are many problems in the current rural biogas construction. Most farmers’ understanding of the role of biogas digesters is limited to daily uses such as "cooking and lighting", and they do not have a deep understanding of the ecological protection and improvement of biogas construction and ...
