Embodiment Construction

[0022] 1. The breeding area 1 is respectively connected with the biogas tank 2 and the breeding waste sedimentation tank 9, and the biogas in the biogas tank 2 enters the hydration through the first one-way gas valve 3, the filter 4, the compressor 5, and the first pressure control valve 6. A dual-purpose device 7 for generating and decomposing matter.

[0023] 2. The sewage settled in the aquaculture excrement settling tank 9 passes through the cold treatment device 10, the first centrifugal water pump 11, and the second one-way liquid valve 12, enters the dual-purpose device 7 for hydrate generation and decomposition, and then enters the dual-purpose device 7 for hydrate generation and decomposition The gas and water provide raw materials for hydrate formation.

[0024] 3. The dual-purpose device 7 for hydrate formation and decomposition first provides a place for hydrate formation. The hydrate formation exothermicly heats the water in the jacket 31 of the cavity, and the ho...

Abstract

The invention relates to a method and a device for treating breeding feces on the basis of a hydrate method. To eliminate adverse influences of a large amount of breeding feces on environment, the breeding feces is treated with a method combining generation and separation of hydrates and a biomass digester. Organic crops are planted by means of clear water and CO2 decomposed by the hydrates and biogas residues in the biogas digester; the separated biogas is used for power generation, and daily production and life demands are met.

Description

technical field [0001] The invention utilizes the characteristics of hydrate formation and separation, and specifically refers to utilizing the hydrate method to purify the biogas while simultaneously realizing the reuse of aquaculture excrement. Background technique [0002] The excrement produced by farming has become an important source of pollution to the environment, and how to deal with these excrement has become an issue of increasing concern to the society. The construction of biogas digesters can reduce the pollution of aquaculture excrement, and at the same time, it can create value. The biogas produced by biogas digesters can be used to generate electricity, but a large amount of carbon dioxide in the biogas reduces the combustion efficiency of biogas. The device uses the hydrate method to purify the biogas, and the purified biogas with high methane content is used to generate electricity to meet basic living and farming electricity needs, and the separated carbon...
