There will be a phenomenon of humid air in different regions and at different times. Hot and humid weather brings a lot of inconvenience to people's production and life, so dehumidification is a problem often encountered in industrial production and people's daily life.
At the same time, various industries also need to have dehumidification requirements in production. When the temperature of the atmosphere drops below the dew point temperature, part of the moisture in the atmosphere will condense into mist or dew, which will cause industrial production that have serious impact.
1. APPLICATION CASE :
1. Automobile manufacturing :
In the painting workshop of an automobile factory, the solvents contained in the paint such as toluene and xylene evaporate rapidly during the painting process, and the temperature of the paint surface drops rapidly. The moisture in the air will condense on the surface and cause the surface of the paint and transparent paint to become dirty. Smooth, the color will become cloudy. At the same time, during heating and baking, the water droplets inside the paint film vaporize and expand, which reduces the quality of the product.
In the high-speed injection molding machine of synthetic resin, if water droplets appear on the inner surface of the metal mold, the volume of the synthetic resin sprayed at high temperature will expand rapidly when it comes into contact with it, and it will eventually become a defective product.
2. Paper industry
Paper is the most hygroscopic material, and changes in humidity can easily cause fiber expansion or contraction, making the surface of the paper uneven or changing the size of the paper
The same humidity has the same effect on wood products. Changes in the humidity of the surrounding air will cause the wood products to open and swell. Therefore, the factory buildings of textile machines or paper machines are required to maintain a certain humidity value.
2. Building industry
Excessive humidity in the air will not only cause corrosion in the building for a long time, but the same biological pollution in the building will also spread and cause diseases in the human body.
3. The role of rotor dehumidification
The dehumidification wheelis divided into a treatment area and a regeneration area by a sealing system inside the dehumidification section. The dehumidification wheel rotates slowly at a speed of 8-10 revolutions per hour to ensure that the entire dehumidification is a continuous process. When the treated air passes through the treatment area of the runner, the water vapor in it is absorbed by the hygroscopic medium in the rotor. The water vapor undergoes a phase change at the same time and releases latent heat. The runner gradually tends to absorb a certain amount of moisture. Saturation; At this time, the processing air becomes dry and hot air due to its own moisture reduction and latent heat release. At the same time, in the regeneration zone, the other way of air first passes through the regeneration heater and becomes high-temperature air (usually 100-140 degrees) and passes through the saturated runner after moisture absorption, so that the adsorbed water in the runner evaporates, thereby The dehumidification capacity of the runner is restored; at the same time, the regenerated air becomes moist air due to the evaporation of water; after that, the moist air is discharged to the outdoors through the regeneration fan.
Through the continuous research and development of dehumidification materials, puresci has developed a new type of energy-saving dehumidification rotor, which can save 25% of regeneration energy while dehumidifying.
