Background
When the old drying oven is used for drying the pigment at present, the method has the characteristics of high energy consumption, large pollution, large labor capacity and the like. In the drying process of the drying chamber, the thickness of the material in the pigment disc is large. When the surface layer of the pigment is dried, the bottom layer material inside the pigment can be dried after a period of time. The diffusion speed of water vapor molecules in the bottom layer material to hot air flowing on the surface of the pigment is slow, and the drying time is prolonged.
The particles of the materials in the pigment disc are large, and the diffusion speed of water vapor molecules and hot air molecules in the particles is slow. The drying speed of the granules is longer as the granularity is larger. The water vapor molecules in the pigment in the shallow layer on the particle surface are relatively quickly taken away by the flowing hot air, and the pigment is dried firstly.
The pollution is large and the pigment loss is large. The paint is blown and contacted by flowing hot air in the oven chamber, and the air can take away the surface material and flow into the atmosphere. Also, when the pigment is poured, the pigment floats in the air, causing gas pollution.
High energy consumption and long drying time. The larger the drying time, the larger the energy consumption. And the quantity of water molecules contained in hot air per cubic meter discharged by the water-saving air purifier is not large, and the water-saving air purifier is also unbalanced in different time values.
