Ventilation system for livestock breeding house

Abstract

The invention discloses a ventilation system for a livestock breeding house, which comprises an in-house air duct arranged in the livestock breeding house and a plurality of terrestrial heat exchange air ducts used for supplying air to the in-house air duct. The terrestrial heat exchange air ducts are arranged underground and used for conducting heat exchange with terrestrial heat, and the terrestrial heat exchange air ducts are connected with the in-house air duct through transition air ducts. A plurality of air inlets for supplying air into the livestock breeding house are formed in the in-house air duct, and a plurality of air outlets for discharging air are formed in the livestock breeding house. Fresh air outside the house exchanges heat with terrestrial heat through the terrestrial heat exchange air ducts, then enters the in-house air duct and is fed into the livestock breeding house through the air inlets, so that the temperature and the air quality in the livestock breeding house meet breeding requirements. According to the ventilation system, on one hand, gas exchange in the livestock breeding house can be achieved, good ventilation in the livestock breeding house is achieved, it is guaranteed that the air quality in the livestock breeding house meets the breeding requirement, and on the other hand, the temperature in the livestock breeding house can be kept within a certain range through terrestrial heat, and the breeding requirement is met.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a ventilation system for poultry breeding houses. Background technique [0002] At present, my country's animal husbandry is in a critical period of rapid transformation and upgrading, and is developing rapidly towards a modern agriculture that integrates scale, intensification, standardization, and ecology, and its production level has also increased accordingly. In winter, most of the breeding sheds are fully enclosed to achieve the purpose of heat preservation and improve the living environment of poultry and livestock. In addition, the internal temperature of fully enclosed breeding sheds is high in summer due to sunlight. Temperature is a key factor affecting the growth of poultry and livestock. How to achieve warm winter and cool summer and ensure the best temperature of the shed is an urgent need. solved problem. But at the same time, due to the unav...

In addition, the internal temperature of fully enclosed breeding sheds is high in summer due to sunlight. Temperature is a key factor affecting the growth of poultry and livestock. How to achieve warm winter and cool summer and ensure the best temperature of the shed is an urgent need. solved problem

But at the same time, due to the unavoidable ventilation problems caused by the fully enclosed type, livestock manure will produce stench. These stench components are volatile fatty acids, alcohols, phenols, acids, aldehydes, ketones, amines, Nine types of organic compounds such as mercaptans and ammonia-containing heterocyclic compounds, and two inorganic substances such as ammonia and hydrogen sulfide. The generation of these harmful gases affects the air quality and produces peculiar smell. When the ventilation is not good, the content of harmful gases will exceed the standard , Ammonia, hydrogen sulfide and other gases are easy to dissolve in the respiratory mucosa and conjunctiva of animals, causing congestion and edema of the mucosa, causing conjunctivitis, bronchitis, pneumonia, and pulmonary edema. If not handled properly, it will affect the growth of poultry and livestock
