Multilayer livestock and poultry house capable of recycling waste gas heat in winter

Abstract

The invention discloses a multilayer livestock and poultry house capable of recycling waste gas heat in winter, and relates to the field of livestock and poultry breeding. The livestock and poultry house comprises a public air duct and a plurality of breeding floors communicating with the public air duct, a waste gas air duct is arranged at the bottom of each breeding floor, the livestock and poultry house further comprises a winter air supply pipeline formed by sequentially connecting a first-stage preheating pipe, a second-stage preheating pipe and an air supply pipe, and an air supply fan is arranged on the winter air supply pipeline; wherein the first-stage preheating pipe penetrates through the public air duct and communicates with the outside of the livestock and poultry house, the second-stage preheating pipe is arranged in the waste gas air ducts, and the air supply pipe is arranged at the tops of the breeding floors and is provided with a plurality of air supply outlets; and the second-stage preheating pipe and the air supply pipe extend from the ends, close to the public air duct, of the breeding floors to the other ends of the breeding floors and communicate with the ends, away from the public air duct, of the breeding floors, and a first waste gas air outlet is further formed in the low position of the wall between the breeding floors and the public air duct. Waste gas heat is recycled and used for preheating fresh air in winter at the same time.

Description

technical field [0001] The invention relates to the field of livestock and poultry breeding, in particular to a multi-layered livestock and poultry house for recycling waste gas heat in winter. Background technique [0002] With the tightening of breeding land and the increasing requirements of environmental protection policies, the land for pig breeding has become increasingly tight, and the introduction of breeding policies allows the construction of multi-storey buildings. In such a situation, a new path has been explored for pig houses in the building mode. According to calculations, raising pigs in buildings saves more than 50% of the land compared with raising pigs in bungalows. At the same time, it also greatly improves the degree of industrialization, intensification and mechanization of pig breeding. . [0003] At present, most buildings and pig houses adopt independent air inlet and outlet systems for each floor, while some buildings try to adopt a centralized ven...
