Why use a three-cylinder dryer for sand drying?
Common types of dryers can be divided into single cylinder and three cylinders according to the external form. When dehydrating and drying sand, why are three-cylinder dryers often used?
1. Compared with the single-cylinder dryer, the volume of the three-cylinder dryer is greatly reduced, which is one-third of the traditional volume, which reduces a large part of the site capital investment for users.
2. At the same time, it consists of three different cylinders embedded with each other according to the design principle. According to the principle of thermal function, lifting plates and guide plates with different angles and spacings are installed in the cylinder, so that the sand can move forward along the direction of the spiral movement under the action of gravity, so that it can stay in the cylinder at a suitable position. Time, and sufficient dispersion, so as to enhance the heat exchange effect between sand and high-temperature airflow, eliminating the wind tunnel phenomenon that often occurs in traditional equipment.
3. It makes the inner cylinder and the middle cylinder surrounded by the outer cylinder to form a self-insulation system. The heat radiated from the surface of the inner and middle cylinders participates in the heat exchange of the materials in the outer cylinder, and the outer cylinder is at the low temperature end of the hot air flow, so the heat dissipation area and heat loss of the cylinder are significantly reduced.
4. In the drying operation, the three-cylinder dryer can make full use of the waste heat, reduce heat loss, increase the heat exchange area, and greatly enhance the evaporation intensity per unit volume, thereby increasing the heat utilization rate, reducing consumption, and greatly improving thermal efficiency. enhanced. At the same time, it further reduces heat loss and environmental pollution, and well realizes the functions of energy saving, emission reduction and low carbon.
