Precise local ventilation airflow organizing mechanism for livestock breeding house and application of precise local ventilation airflow organizing mechanism

Abstract

The invention relates to the field of breeding environment control, and particularly discloses a precise local ventilation airflow organizing mechanism for a livestock breeding house and an application of the precise local ventilation airflow organizing mechanism. The precise local ventilation airflow organizing mechanism comprises an air supply assembly, an air return assembly and an exhaust assembly. The air supply assembly comprises an air supply main pipe, an air supply branch pipe and an air supply opening, and the air supply opening is formed in the upper portion of a breeding fence and faces downwards; the air return assembly comprises an air return main pipe, an air return branch pipe and an air return opening. The air return opening is formed in the middle or the upper portion of the breeding fence. The exhaust assembly comprises an exhaust channel and an exhaust opening, the exhaust channel is arranged on one side or two sides of a manure pit, the exhaust opening is formed in the upper portion of the side wall of the manure pit, and the exhaust channel communicates with the manure pit through the exhaust opening. According to the precise local ventilation airflow organizing mechanism for the livestock breeding house and the application of the precise local ventilation airflow organizing mechanism, through precise local short-range air supply, air return and air exhaust and scientific and reasonable air distribution, ventilation distribution is more uniform, waste gas backflow is reduced, the concentration of harmful gas in a livestock living area is effectively reduced, the livestock isolation effect is optimized, cross contamination and germ transmission are reduced, and the ventilation quantity and energy consumption are effectively reduced.

Description

technical field [0001] The invention relates to the field of breeding environment control, in particular to a precise local ventilation airflow organization mechanism for poultry and livestock breeding houses and its application. Background technique [0002] With the development of the modern breeding industry, centralized large-scale poultry breeding houses are becoming more and more advanced and efficient. In order to cope with the decline in air quality caused by a large number of intensive breeding, resulting in poor breeding environment and affecting the health and meat quality of livestock, the fresh air system And the ventilation system is used extensively. [0003] However, most of the existing environmental control systems for poultry breeding houses adopt a comprehensive ventilation method. There are several defects in the technical scheme of comprehensive ventilation: [0004] 1. When the air-conditioning system is used as the environmental control method, the ...
