How to properly install and use mist spray cooling systems in pig farms

The hot weather is a severe test for pig farmers. When the ambient temperature of the pig pen reaches more than 30 ° C, pigs are very prone to heat stroke, especially fat pigs . Therefore, doing a good job in summer heat prevention and cooling is very important to maintain uniform litter production and improve efficiency, and it is one of the primary tasks of pig farms in summer.
 


There are many ways to prevent heat in summer, and there are many machines and equipment. Today, us would like to share with you the correct use of mist spray cooling in pig farms. The biggest advantage of the mist cooling method is that the current poultry house is easy to install and use, and the mist cooling speed is relatively fast. The indoor temperature can be reduced by 5 to 8 ° C within 5 to 10 minutes, and the mist spray equipment can also be disinfected and sterilized at the same time.

Mist spray cooling, the use of pressurized water, through the mist nozzle, the formation of small droplets, floating in the greenhouse air, with the air heat and humidity exchange, to achieve the actual effect of mist cooling.
 
However, the mist  spray will hit the wetland surface, causing water on the ground, so that the pigs are in a high ambient humidity environment for a long time, causing harm to the environmental health of the pig pen. Therefore, when using the mist  spray device to cool down, special attention should be paid to the use of methods, mainly including the selection of three aspects of the mouth, the installation of the relative height of the nozzle and the spray time.
 

First, the selection of mist nozzle

The key is to mist the nozzle well. The performance of the mist nozzle directly harms the mist quality, and the mist quality directly harms the actual cooling effect. A nozzle with excellent performance can not only ensure excellent mist effect, but also consume low energy. For example, fine fog, even if it does no harm to the ambient humidity of the fermentation bed, because the water rarely falls into the mat, it is mist in the air, absorbs the heat in the air and evaporates, and will not fall onto the bed.

Second, the relative height of mist nozzle installation and use

The droplet travels inside the pigpen. Due to the initial velocity and gravity of the droplets, the mist droplets will move downward. If the small droplets are inhaled by pigs, it is very easy to cause respiratory infections. From this point of view, the running space of fog droplets in the pig pen has certain limitations, that is, the fog droplets should completely evaporate above the back height of the pig, that is, the relative height above the pig pen should completely evaporate. The actual relative height is determined by the pressure of the selected nozzle and the equipment Angle of the nozzle.
 

Third, the mist spray time adopts intermittent operation

When the mist spray is cooled, the moisture content in the air increases with the decrease of the ambient temperature. After a certain time (about 1-2 minutes according to the test), the moisture and heat balance is reached, and the water vapor content of the indoor air is close to saturation. Therefore, the mist nozzle must work periodically and intermittently, which depends on the ambient temperature, ambient humidity, ventilation and other conditions.
