The tunnel type gas drying kiln, including the dry compressed air heating system, drying the box shaped workpiece and drying the inside of the box shaped workpiece and heating the compressed air after dehydration, and then introducing the heat and mass transfer to the inside of the box shaped workpiece and taking the water vapor out of the box shaped workpiece and hot air at the same time. Circulating heating outside the box-shaped workpiece, drying the box-shaped workpiece shell and the humid air discharged from the body to ensure that the water content of the box-shaped workpiece to meet the requirements.
The tunnel type gas drying kiln is specially designed and manufactured by our factory in recent years with the field certification for the drying and heat treatment of mineral products with the domestic fire research and Design Institute and the large and medium-sized refractory industrial and mining enterprises. It is mainly suitable for the dehydration and drying of different refractory products and the curing and decomposition of non metal articles containing chemical components. The products made of minerals, semi finished drying and heat treatment have the advantages of strong decomposition penetration, fast drying and heat treatment.
The product is automatically controlled by PID. The automatic heating up, automatic constant temperature and automatic wetting can not only meet the production process requirements, but also improve the working efficiency, reduce the labor intensity and greatly reduce the energy consumption and environmental pollution. The product has the precision of control temperature, uniform uniformity, low temperature difference and stable performance. It has the characteristics of convenient and flexible operation, safe and reliable.
