Ventilation system applicable to pig houses

Abstract

The invention relates to a ventilation system applicable to pig houses. The ventilation system comprises a chimney exhaust fan, a central channel, a dedusting and deodorizing heat recovery system, anair inlet pipe, air intake systems and a high-pressure chimney fan. The central channel is arranged at the top end of a pig house. The chimney exhaust fan is mounted at the top of the pig house and communicated with the central channel. The dedusting and deodorizing heat recovery system is arranged at an external end of the pig house. The high-pressure chimney fan is arranged at an external end, provided with the dedusting and deodorizing heat recovery system, of the pig house. One end of the dedusting and deodorizing heat recovery system is communicated with the central channel through the air inlet pipe. The other end of the dedusting and deodorizing heat recovery system is communicated with the high-pressure chimney fan. The air intake systems are arranged on two side walls of the pig house. The ventilation system has the advantages that the dedusting and deodorizing heat recovery system filters out hydrogen sulfide, dust and harmful gases such as ammonia, fresh air entering the pighouse is heated through heat generated by a heat exchange tube set, the illness possibility of pigs is reduced, air pollution is avoided, resources are saved, the environment of the pig house is improved, and heat recovery is realized.

Description

technical field [0001] The invention relates to a ventilation system suitable for pig houses. Background technique [0002] With the development of human industry and the large-scale development of the breeding industry, most of the current pig breeding adopts highly intensive and automated breeding, with high breeding density and closed air circulation in pig houses. The decomposition of organic matter such as pig manure and urine will produce ammonia gas, which will cause respiratory diseases in pigs, and the carbon dioxide content in pig houses is often many times higher than that in the atmosphere. Pigs themselves will produce a lot of carbon dioxide. Coal is used for heating in winter. The concentration of carbon dioxide is high. If the concentration of oxygen is low, insufficient combustion will produce carbon monoxide and hydrogen sulfide. Carbon dioxide itself is non-toxic. Its harm is mainly caused by hypoxia and chronic poisoning. Pigs in a hypoxic environment for...

Problems solved by technology

Long-term exposure of pigs to an oxygen-deficient environment can lead to listlessness, loss of appetite, physical decline, reduced productivity, and weakened resistance to diseases. Carbon monoxide is toxic and can poison pigs
