Technical Field

The invention relates to a ventilation system suitable for a pigsty.

Background

With the development of human industry and the large-scale development of breeding industry, the existing pig breeding mainly adopts highly intensive and automatic breeding, the breeding density is high, and the sealed air of a pigsty is not circulated. The decomposition of organic matters such as pig manure and urine can generate ammonia gas, the ammonia gas can cause the pigs to have respiratory diseases, and the content of carbon dioxide in the pigsty is often hundreds of times higher than that in the atmosphere. The pig can generate a large amount of carbon dioxide, the pig is heated by coal in winter, the carbon dioxide concentration is high, the oxygen concentration is low, the combustion is insufficient, carbon monoxide and hydrogen sulfide can be generated, the carbon dioxide is non-toxic, and the harm of the carbon dioxide is mainly oxygen deficiency and chronic toxicity. Long-term hypoxia of pigs leads to listlessness, loss of appetite, decreased constitution, decreased productivity, and weakened resistance to diseases, while carbon monoxide, which is toxic, poisons the pigs.
