How to Properly Use Spraying Cooling Measures in Pig Farms

High temperatures pose a severe test for pig producers. When the temperature in the pigsty exceeds 30 degrees, pigs are prone to heatstroke, especially large pigs and pregnant sows. Therefore, doing a good job in heat and cold prevention is crucial for maintaining balanced reproduction and improving efficiency. Spray cooling is one of the main tasks in pig farms during summer. Now, let's learn how to correctly use spray cooling measures in pig farms!

There are many methods and devices for heat prevention. Today, the editor wants to share the correct application of spray cooling in pig farms. The main advantage of this cooling method is that it can be easily added to existing livestock houses, and the cooling speed is fast, reducing the indoor temperature by 5-8 degrees in 5-10 minutes. The spray device can also disinfect.

Spray cooling uses pressurized water, which turns into a fine mist after passing through the nozzle, dispersing into the air inside the greenhouse and exchanging heat and moisture with the air, effectively lowering the evaporation temperature.

However, showering will wet the ground, causing water to accumulate on the floor. If pigs are placed in a high-humidity environment for a long time, it will harm the environmental hygiene of the pigsty. Therefore, special attention should be paid to the usage method when using shower devices for cooling. This mainly involves the selection of shower heads, the installation height of shower heads, and the spray time.

First is the selection of the nozzle, where the important factor is the atomization of the nozzle. The performance of the nozzle directly affects the quality of atomization, which in turn directly affects the cooling effect. A good performance nozzle can not only provide a good atomization effect but should also consume low energy. If it turns into mist, it does not harm the humidity of the fermentation bed. Because water generally rarely falls on the mat, it atomizes in the air, absorbing heat from the air and evaporating without falling on the floor.

Second is the installation height of the nozzle. The water mist in the pigsty works downward under the initial speed of the mist and the force of gravity. Since small mist is easily inhaled by pigs, it can lead to respiratory diseases. From this perspective, the space for mist operation in the pigpen has certain limitations, meaning that the mist completely evaporates above the height of the pigs. The specific height depends on the pressure of the selected nozzle and the installation angle of the nozzle.

Third is the spray time, which adopts an intermittent operation mode. After spray cooling, the moisture content in the air increases as the temperature decreases. After a certain period (about 1-2 minutes according to experiments), a humid heat balance is reached, and the water vapor content in the indoor air approaches saturation. Therefore, the nozzle must work intermittently, and the specific situation varies depending on temperature, humidity, ventilation, and other conditions.

Spray cooling is generated by a high-pressure pump that produces high-pressure water, which reaches the nozzle through a high-pressure pipeline system and sprays fine water mist. Each part has different functions, with each part responsible for different modules. Water treatment device: Different water treatment methods are implemented according to the different actual situations in different regions. For example, when using municipal water, only a three-stage household filter is needed for re-filtering to prevent the spray head from clogging for a long time.
