Replaceable ventilating system

Abstract

The invention discloses a replaceable ventilating system, and relates to the technical field of ventilating systems. The replaceable ventilating system is applied to a farm plant of a multi-storey building structure. Each storey is internally provided with a corridor for making two sides of the same layer communicated. The two opposite sides of each corridor are each provided with a plurality of hog houses in a spaced mode. Each storey is provided with a partition layer located below the corresponding hog houses. The ground between the hog houses of each storey is provided with a plurality ofvent holes communicated with the corresponding partition layer. The two opposite ends of each storey are each provided with an air inlet channel which is communicated with the corresponding partitionlayer. The corridor of each storey is provided with an air outlet channel communicated with the corresponding vent holes. The air outlet channels of all the storeys are communicated with one another.The sides, facing the corresponding hog houses, of the air outlet channels of each storey are each provided with a plurality of air outlets. A first exhaust fan is installed on each air outlet. A chimney communicated with a plurality of air outlet channels is arranged on the roof of a building. The replaceable ventilating system can keep air circulation in the hog houses.

Description

technical field [0001] The invention relates to the technical field of ventilation systems, in particular to a displacement ventilation system. Background technique [0002] With the continuous scale and modernization of the pig farming industry, more and more modern large pig farms have emerged. All pig farms have the characteristics of a large number of pigs and a high density. In a relatively closed environment like a pig house, the air quality directly affects the health of the pigs. Good ventilation design can not only provide a comfortable environment for the pigs, but also improve the health of the pigs. The health level of the herd can be improved, the occurrence of diseases can be reduced, and the cost of feeding and management can also be reduced, so as to achieve twice the result with half the effort for pig farm breeding. [0003] In order to ensure the air quality in the pig house, large pig houses are now equipped with ventilation devices. In addition to insta...

AI Technical Summary

Problems solved by technology

Such a device has the following disadvantages: the ventilation effect is poor, the flow of air stays above the pig house, the air exchange under the pig house is slow, and there will be dead corners in the pig house, which is not conducive to maintaining the fresh air circulation under the pig house, while the pig house below The pig manure is the main source of dirty air in the pig house. The odor of pig manure cannot be exchanged by the fresh air, and the air quality is still bad, which cannot achieve the expected effect of improving the air quality of the pig house.
