The principle and regular maintenance of wet curtains in pig farms
Before installing the wet curtain, it is necessary to make a wooden frame to ensure that the frame is sturdy and the waterway is reasonable before installing the wet curtain paper. A wooden frame that is easy to install will give you a solid foundation. The water pump distributes water to the upper distribution pipe, which always drips water towards the wet curtain to keep it moist. The sink collects water from the wet curtain to maintain a good water circulation, and the sink can always maintain a certain water level (toilet principle), so that the wet curtain can maintain effective operation.
Wet curtain is a special type of paper honeycomb structure material, which works based on the natural physical phenomenon of “water evaporation absorbs heat”. Under the influence of Earth’s gravity, water flows from top to bottom, forming a water film on the corrugated fiber surface of the wet curtain. When rapidly flowing air passes through the wet curtain, the water in the water film evaporates after absorbing heat from the air, taking away a large amount of heat, reducing the temperature of the air passing through the wet curtain and achieving the goal of cooling.
What is the wet curtain structure of a pig farm?
The wet curtain paper in the wet curtain has a honeycomb structure and is produced by processing the raw paper. The production process roughly includes sizing, drying, pressing corrugated, shaping, gluing, curing, slicing, grinding, and deodorizing. In China, there are usually three types of wave heights: 5mm, 7mm, and 9mm, with ripples of 60 ° × 30 ° staggered opposition, 45 ° × 45 ° staggered opposition, generally designed with negative pressure.
How is the cooling in the pigsty achieved?
High quality wet curtains are generally made of new generation polymer materials and spatial cross-linking technology, with advantages such as high water absorption, high water resistance, mold resistance, and long service life. Moreover, the evaporation is greater than the surface, with a cooling efficiency of over 80%. It does not contain surfactants, naturally absorbs water, has a fast diffusion speed, and has a long-lasting effect. A drop of water can diffuse in 4-5 seconds.
Why do cooling water curtain fans from the same manufacturer and negative pressure fans from the same manufacturer have different cooling effects? What factors are causing it? Let’s explore some excellent factors of the water curtain fan cooling system together. Interested friends can take a closer look! Without further ado, let’s get to the point. Advantages of using cooling water curtains and aluminum alloy wet curtains in aquaculture farms
When the floor exceeds 5.5 meters, the number of negative pressure fans must increase, otherwise the exhaust air volume will be insufficient, which will affect the cooling effect
2. When using a fan, we must choose a fan with sufficient exhaust air volume. * * Use 146 * 146 * 58cm, with an air volume of 46000~48000m/
The thickness of the water curtain fan can be customized according to the situation of the window, which is good
4. The side equipped with a water curtain should not have any other air inlet. As the resistance of the air inlet through the empty window is much smaller than that through the wet curtain, in order to allow air to pass through the wet curtain as much as possible to achieve cooling, there should not be too much gap on the opposite side of the negative pressure fan (i.e. the side of the water curtain).
The water curtain fan mainly uses the principle of evaporation to absorb heat for cooling. The operating principle of water curtain cooling is a circulating water pump, which continuously draws out the water from the receiving tray and forms a water film on the surface of honeycomb fiber paper through a water distribution system. When air passes through the water curtain, the water exchanges heat and evaporates to achieve cooling and cooling. Clean air is then pressurized and sent into the room by a low noise fan, To achieve a cooling effect. This product solves the pollution of the atmosphere caused by conventional air conditioning, and the water curtain can also bring comfort to people. The usage cost is 1/3 of that of conventional air conditioning, which is both cost-effective and environmentally friendly.
