Greenhouse based on multi-energy coupling dual heating and CO2 autonomous regulation and control

Abstract

According to the greenhouse based on multi-energy coupling dual heating and CO2 autonomous regulation and control, in the daytime, a double-glass photovoltaic panel and wind energy are combined for power generation, and all electric quantity is stored in an electric power storage box; circulating water is pumped out of the water storage tank and pressurized by a water pump to cool the double-glass photovoltaic panel firstly, then high-temperature water subjected to heat exchange exchanges heat with the energy storage tank, and cooling water is used for carrying out cold cracking treatment on the electrolytic raw material liquid; feeding the treated raw material solution into a microbial electrolysis tank for electrolysis, and storing heat in an energy storage box in the electrolysis process; the generated CH4 is further combusted and filled into a CO2 air bag, and at the moment, a controller located in front of the air bag is connected with a CO2 concentration detector, and the CO2 concentration is autonomously balanced according to the feedback effect and free diffusion. At night, wind power generation continues to be carried out, photovoltaic cooling stops, circulating water directly exchanges heat in the energy storage box, cold cracking treatment and electrolysis continue to be carried out, the electricity storage box fully charged in the daytime continuously supplies power to a central air conditioner in the greenhouse for work, two parts of heat stored in the energy storage box are completely exchanged into the greenhouse to be released, and heat and power combined heating is achieved.

Description

technical field [0001] The invention relates to a multi-energy coupling dual heating and CO 2 The self-regulated greenhouse belongs to the technical field of combined application of solar energy, wind energy, biomass energy and thermal energy. Background technique [0002] For areas dominated by grasslands with strong winds and abundant sunshine all year round, wind energy and solar energy are the two renewable energy sources with the widest distribution and the highest potential utilization value. But usually the bad weather in these areas will have a serious impact on the growth of crops, so people began to use various large greenhouses to cultivate plants and breed them. [0003] For the greenhouse, the CO in the shed 2 Concentration control and greenhouse heating at night have always been research hotspots. Especially for these specific areas, the temperature difference between morning and evening is large, and the temperature at night is very low. If you do not set u...
