Jiangsu-up green three drum dryer drum dryer CDSH type three is the introduction of advanced technology in today's Germany, dryer consists of three concentric cylinders of different diameters in accordance with certain mathematical relationships and structure, embedded in combination with each other a. According to the principle of thermal power, cylinder with different angles and spacing of lifting plate and the guide plate, this structure can ensure the material is dried under gravity along the direction of motion of the spiral movement, in the barrel to maintain sufficient residence time and adequate degree of dispersion, so that material in the barrel with the hot gas stream from the combustion chamber is sufficient heat exchange, eliminating the conventional drying equipment often appear small cross-sectional area of ??the heat exchange caused by the wind tunnel, low evaporation intensity of defects per unit volume . Special three-cylinder structure, the inner cylinder and the cylinder is surrounded by an outer cylinder to form a self-insulation system, inside the cylinder surface of the heat involved in the outer layer of the material of the heat exchanger tube and the outer tube again at hot air at a low temperature side, so the heat dissipation area and heat losses significantly lower cylinder. Energy-efficient three-cylinder drying function full use of waste heat, reduce heat loss and increase the heat exchange area, so that the dryer unit volume of evaporation intensity greatly improved, thus effectively improving the thermal efficiency, reducing energy consumption, so that the three cylinder drying the thermal efficiency of the dryer has been dramatically increased. Due to the special structure of the three drum dryer, the length of the barrel is third single cylinder dryer, basic area than the single cylinder dryer can save about 65%, infrastructure investment reduced accordingly. The dryer uses friction drive belt idler wheel, transmission power is low, the device reduces the noise at work. Sealing system uses a micro-contact technology, seal better, reduce dust pollution. Three drum dryer can be adapted to a variety of fuels coal, oil, gas, etc., can be drying massive, granular, powder and other materials to create environmentally friendly in line with national policy resource-saving society, is an alternative to the traditional bake Dry equipment and environment friendly products. Features: 1, high technology content, self-cylinder insulation, thermal efficiency up to 80% (monocular dryer thermal efficiency of only 35%), compared with 68% of single cylinder drying economizer, production increased by 100%. 2, single cylinder dryer than 60% shorter overall length, help process layout. Reduce plant construction area, saving about 40% of project investment. Covers an area of ??about 20m2. 3, heat-resistant alloy steel plate, wear-resistant than ordinary steel plate 4 times. Long life, easy maintenance. 4, high thermal efficiency, the outer cylinder temperature is below 60 ℃ (monocular dryer outer cylinder temperatures up to 150 ℃), the outlet temperature is low, the material temperature is below 60 ℃. 5, the outlet temperature is low, is conducive to dust removal device for a long time, can be directly supporting the air box pulse bag filter. 6, construction investment reduced by about 50%, 60% reduction in power consumption. 7, no size gears, the use of wheel rotation. 8, can be equipped with boiling hot stove stove, coal stove spray, hand burning stove, also used in the oil, gas stove, to bake 30 mm below the lump, pellets and powder materials.
