Jiangsu fertilizer farm positive pressure ventilation renovation project

Project profile

The farm has been upgraded with a positive pressure ventilation system, which has improved the environmental quality and biosecurity of the farm, reduced the risk of disease transmission, and improved the overall health and productivity of the pigs.

Project background

In traditional pig farms, negative pressure ventilation mode is commonly used in winter, which is easy to cause external pathogens to flow into the pig house with the air, increasing the risk of disease transmission. Especially in the coming winter, it may have a negative effect on the health of the pig population.

Reconstruction target

◆Achieve low cost, sub-efficient air filtration.

◆Optimize the air flow distribution in the pig house to ensure the appropriate wind speed in the pig movement area.

Reconstruction scheme

◆Positive pressure air filter module: equipped with the initial effect and sub-high efficiency filter, through the positive pressure air supply mode, so that the house air pressure is higher than the outside pressure, the pig house air one-way flow, with the pipeline to transport fresh air to the pig house.

◆Accurate air supply: with indoor ventilation pipes, uniform and accurate air supply can be achieved.

◆Strengthen the air tightness: the air tightness of the pig house is reformed to achieve the effect of positive pressure ventilation and reduce the risk of invasion of external pathogens.

Implementation effect

◆Biosafety improvement: The positive pressure ventilation system sends filtered fresh air into the pig house, making the air pressure inside the pig house higher than the outside world, preventing the invasion of external pathogens, effectively reducing the risk of pathogen transmission, and improving the biosafety level of the pig farm.

◆Ventilation efficiency optimization: Through the positive pressure ventilation system and precise air supply design, the air flow distribution inside the pig house is optimized to ensure the appropriate wind speed in the area where the pigs are moving, thus enhancing the ventilation efficiency.

◆Improved production efficiency: Through the optimization of the ventilation system and feeding environment, the growing environment of pigs has been improved, and the growth rate and health status have been improved.

Through the renovation project of positive pressure ventilation, not only the biosafety level has been improved, but also the ventilation efficiency has achieved remarkable results. In addition, the growing environment of the pigs has been optimized, and the production performance has also been improved. This successful case provides valuable reference and reference value for other pig farms of the same type, and shows the development trend and direction of modern pig farms.
