Biogas, wind energy and solar energy integrated ecological circulation system

Abstract

The invention provides a biogas, wind energy and solar energy integrated ecological circulation system, which mainly comprises a wind energy and solar photovoltaic composite electricity generating unit, an electric storage unit, a biogas generation unit, a marsh gas and solar composite utilization unit, a biogas slurry heating device, a cold-warm air circulating exchange unit and a livestock sunlight greenhouse, wherein the wind energy and solar photovoltaic composite electricity generating unit is used for outputting electric energy and conveying to the biogas slurry heating device and the electric storage unit; the biogas slurry heating device is used for heating the biogas generation unit; a toilet, a livestock shed and a vegetable garden are built in the livestock sunlight greenhouse; and biogas residues and biogas slurry generated in the biogas generation unit are conveyed to the vegetable garden or returned to a grassland. The wind energy and solar energy of low-temperature alpine regions and biogas clean energy generated by human and animal excreta are fully utilized; the living quality of pastoral area herdsmen is improved; the ecological environments of the grasslands and forests of the pastoral areas are effectively protected; the air pollution emission is reduced; and sustainable utilization of the green clean energy is realized.

Description

technical field [0001] The invention relates to the field of green and clean energy recycling, in particular to an ecological cycle system integrating biogas, wind energy and solar energy. Background technique [0002] In my country's Qinghai-Tibet Plateau and other alpine grassland pastoral areas, the climate is very cold due to the high altitude. Therefore, herdsmen mostly use three combustible materials such as yak and other livestock manure, wood and coal for cooking, milk and heating. [0003] Women in the pastoral areas pick up the burned manure of yaks and other livestock with their hands, spread it on the grass or walls to dry, and then collect it for storage. Not only is the labor intensity of women high, but also due to the limited conditions in pastoral areas, women in pastoral areas often use the hands that have just picked up cow and sheep dung to take bowls, chop vegetables, and cook rice. Many and infected with microorganisms such as parasites and spores and...
