Environmentally-friendly energy-saving greenhouse device utilizing biogas energy

Abstract

The invention discloses an environmentally-friendly energy-saving greenhouse device utilizing biogas energy. The greenhouse device is characterized by comprising a greenhouse body and a greenhouse roof. The greenhouse device is characterized in that the greenhouse roof comprises a plurality of ceilings of sawtooth shaped structures, the ceilings are provided with rollable plastic film to form a skylight which can be closed and opened, a sunshade net is arranged above the ceilings, roll-up plastic film is arranged on both sides of the greenhouse body, and water curtain systems and fan devices are respectively arranged at the two ends of the greenhouse body; the greenhouse roof is made of gas film; a biogas system is arranged below the greenhouse body, the biogas system includes a biogas tank and a power generation device connected to the biogas tank and used for generating electricity by using biogas, and the power generation device is electrically connected with the water curtain systems and the fan devices; a garbage dumping passage is arranged in the greenhouse, the garbage dumping passage is connected with the biogas tank, and an air purification system is arranged in the greenhouse. According to the greenhouse device, the biogas system is arranged for biogas fermentation of organic wastes such as vegetable leaves, rotten fruits and vegetables, and the like in the greenhouse, and the greenhouse device is energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to an environment-friendly and energy-saving greenhouse device utilizing biogas energy. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and...

Problems solved by technology

[0003] However, the organic waste such as vegetable leaves produced by the current greenhouse device needs to be dumped outside, which pollutes the environment and has a low utilization rate. The greenhouse also needs to consume part of the electric energy for ventilation and heating. This problem needs to be solved urgently.
