Description
Technical Field
The invention relates to the field of ventilation of livestock breeding buildings, in particular to a novel ventilation system of a livestock multi-story building.
Background
Since the implementation of the pollution control regulations for livestock and poultry scale cultivation in 1 month and 1 day 2014, environmental protection policies are intensively released, and the cultivation land is tense every day. The Chinese population is large, and the consumption of livestock and poultry products is huge. The disadvantage that the traditional single-layer livestock and poultry house occupies a large area is increasingly prominent, especially in hilly and mountainous areas. With the intensive emergence of national environmental protection policies, breeding land is increasingly tense, and under the situation, in order to save pig raising land, a new road is explored for a building type pigsty, the building type pigsty can fully excavate the potential of land, and the land utilization rate is improved by utilizing high-rise space so as to improve the yield of live pigs in unit area. The breeding mode provides a better solution strategy for relieving the contradiction between the breeding amount and the land resources, and meanwhile, the facility equipment utilization of the multi-layer pigsty is more intensive, and the production efficiency can be better improved.
The building pigsty has complex building structure and high feeding density, and once serious infectious diseases occur, cross infection is easy to occur, and the disease control is difficult, so the biological safety prevention and control become more important. As a highly intensive modern high-efficiency pig farm, ventilation between every floor should be strictly distinguished, cross infection should not exist, and the principle of 'one-way flow' should be strictly followed.
For intensive efficient pig farms, the thermal environment and air quality in the house are critical to the health of the animals and breeders. Researches show that poorer indoor environmental conditions can generate larger negative effects on the production performance, behaviors and health of pigs, so that the feed efficiency is reduced, and the daily gain is reduced. Ventilation is a common and effective way to provide and maintain a comfortable indoor environment for the herds in the house, not only to remove excess heat and moisture, but also to introduce fresh air to the pigs. Pig raising in buildings is different from pig raising in a single-storey house, and due to the lack of building structures such as attics and the like, ventilation structures such as a roof fan, a roof air inlet and the like cannot be adopted in the design of a mechanical ventilation system in a pigsty; in the design of a mechanical ventilation system of a building type pigsty, most of domestic building pigsties are designed in a longitudinal ventilation mode or a transverse ventilation mode, the two ventilation modes can ensure the ventilation quantity of the livestock and poultry house, but due to the design of the ventilation system, the cooling in summer and the ventilation in winter are not uniformly distributed, and the damage to livestock and poultry production is caused.
In order to deal with risks brought by African swine fever and adapt to increasingly strict environmental requirements, the biological safety level of the existing large-scale pig farm is greatly improved, and in a ventilation system, the energy consumption of a fan and the installation space of equipment are not reduced on the premise of reducing the risk of diseases spreading through air.
