Ventilating system for cross infection preventing closed animal house

Abstract

The invention relates to a ventilating system for a cross infection preventing closed animal house. The ventilating system is characterized by comprising an air supply system and an air return system, wherein the air supply system is arranged at the inner roof of the animal house, and the air return system is arranged at the lower parts of two side walls; the air supply system comprises an air supply fan connected to the outer part of the animal house, one end of an air supply main is connected with the air supply end of the air supply fan, and the other end of the air supply main is communicated with a plurality of branched air supply pipelines which are arranged on the roof and are arranged in parallel in a length direction and air outlets are formed in the side walls of the branched air supply pipelines; the air return system comprises an air return fan connected to the outer part of the animal house, one end of an air return main is connected with a certain end of the air return fan, and the other end of the air return main is communicated with two branched air return pipelines which are arranged at the lower parts of the two side walls in parallel and are arranged in a length direction, and exhaust holes are formed in the side walls of the branched air return pipelines. According to the ventilating system provided by the invention, the air supply system is arranged in the animal house and the air return system is arranged at the lower parts of the side walls, therefore the ways that clear air enters in the upper part of the animal house and dirty gas is exhausted from the lower part of the animal house can be realized, and the longitudinal and transverse cross infection of bacteria of the animal house can be effectively prevented.

Description

technical field [0001] The invention relates to a ventilation system, in particular to a closed livestock and poultry house ventilation system for preventing cross-infection. Background technique [0002] In order to make better use of the production capacity of poultry and livestock, it is usually necessary to carry out reasonable ventilation in hot and cold seasons to improve the hot and humid environment and air quality of livestock and poultry houses. The existing ventilation methods of livestock and poultry houses mainly adopt natural ventilation and mechanical ventilation. Among them, the mechanical ventilation mainly adopts longitudinal negative pressure ventilation and horizontal and vertical mixed ventilation. In large and medium-sized livestock and poultry houses, in order to prevent the invasion of germs outside the house and maintain a relatively controllable breeding environment and modern breeding conditions in the house, a fully enclosed livestock and poultry...

AI Technical Summary

Problems solved by technology

However, this ventilation method not only consumes a lot of energy and has low ventilation efficiency, but also causes stress reactions in poultry and livestock if the air and temperature distribution in the house is not uniform during ventilation.

Moreover, if the length of the longitudinal ventilation is longer, the dirty air will spread in the house with the air flow, causing cross-infection of pathogens in poultry and livestock
