Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to a ventilation system for a sow pig house. Background Art

[0002] Proper ventilation of pig houses is not only beneficial for preventing heatstroke in summer, but also can remove water vapor and harmful gases such as carbon dioxide, ammonia, and hydrogen sulfide in the house, ensuring dryness in the house and improving air hygiene. If the pig house is not ventilated enough, excessive accumulation of water vapor, toxic and harmful gases, dust, bacteria, etc. in the house can lead to chronic poisoning of pigs, reduced appetite, decreased productivity, and increased morbidity and mortality.

[0003] When raising sows in pens, attention should be paid to ventilation. Not only the temperature inside the pig house should be considered, but also the air quality and the odor in the exhausted air. Currently, when raising pigs in pens on the market, most of the odorous air is discharged without treatment, which increases the environmental pollution rate.

[0004] When applying for the present invention, the applicant searched and found that a Chinese patent disclosed a "ventilation system for pig houses" with the application number "202221000614.6". The patent mainly replaces the air in the pig house effectively, and the spray system in the side room can effectively kill harmful bacteria in the outside air and reduce the illness of pigs. However, the patent does not process the replaced air, which may cause air pollution. Utility Model Content
