Background

With the tightening of breeding land and the higher requirements of environmental policy, pig breeding land is increasingly tense, and breeding policy is promoting to allow the construction of multi-storey buildings. Under the situation, a new road is explored in the building mode pigsty, through measurement and calculation, the land for pig raising in the building is saved by more than 50% compared with that in a flat house, and meanwhile, the factory, intensification and mechanization degrees of pig raising are greatly improved.

At present, most of buildings adopt an independent air inlet and outlet system on each floor, and partial buildings adopt a centralized ventilation mode. The centralized ventilation of the building is characterized in that all fans are installed at the top end of the building, and the fans discharge the waste gas of each pigsty out of the building through a common air duct. In winter ventilation, exhaust gas from buildings carries a lot of heat, which is all concentrated to a common exhaust duct.

In order to reduce heating investment and environmental protection pressure, more and more pig farms ventilate in winter in a preheating mode. However, the preheating pigsty is mostly a one-storey pigsty, and the heat discharged from the building pigsty is difficult to utilize.
