A three-dimensional livestock breeding system that realizes energy saving, environmental protection and biological safety

Abstract

The invention discloses a three-dimensional livestock breeding system for achieving energy conservation, environment protection and bio-safety. The three-dimensional livestock breeding system comprises a multi-layer building, wherein except the lowest layer, the other layers are breeding layers; an air filtration device, a terrestrial heat ventilating pipeline and so on are arranged in the lowestlayer; an air inlet pipeline, a gutter air dust and so on are arranged in each of the breeding layer; the three-dimensional livestock breeding system is also provided with a waste gas chamber; the whole system is formed by a waste gas heat recovery system, an earth source heat preheating (precooling) system, an in-house ventilating system, an epidemic prevention system and so on. According to thethree-dimensional livestock breeding system, by controlling a route of transmission of air into a house, epidemics can be effectively prevented, and the grade of bio-safety is increased; by arrangingthe terrestrial heat ventilating pipeline, the house can be preheated or precooled by utilizing earth source heat, so that the fluctuation of temperature in the house is reduced, the heat (cold) stress of swine herds can be prevented, and the energy consumption of a heat (cold) load of the building is reduced. Additionally, according to the three-dimensional livestock breeding system, the heat ofwaste gas can also be effectively utilized, so that energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding facilities and equipment, in particular to a three-dimensional livestock breeding system that realizes energy saving, environmental protection and biological safety. Background technique [0002] Livestock products are one of the important sources of human protein. China has a large population. Taking the pig industry as an example, the annual consumption of pork exceeds 5 billion tons, and the required live pigs are close to 700 million. Huge amount of livestock needs to occupy a large amount of agricultural land, while China has a large population and relatively scarce land resources, resulting in increasingly prominent contradictions between humans and animals competing for land. At the same time, the government's requirements for livestock land approval and environmental protection are becoming more and more stringent. Under the multiple pressures of land, environmental ...

Problems solved by technology

Due to the structural constraints of the wet curtain itself, when the outdoor temperature is too high and the humidity is too high, the cooling effect of the wet curtain is limited, and the heat stress of the pigs is obvious.
