Application process of GS series rotary tube bundle dryer/cooler

　　GS Series Rotary Tube Bundle Dryer/Cooler is a dryer for processing large-volume materials. It is suitable for drying powdery, granular, lumpy, and paste-like materials mixed with dry materials. It can be divided into three types: direct heating type, conduction heating type, and composite heating type according to the contact mode of the processed material and the cold and heat carrier. The direct heating type is mainly suitable for the drying process of materials with large particles that are not afraid of pollution and cause no environmental pollution. The conduction heating type is suitable for drying materials with a long deceleration drying stage and heat-sensitive materials. The compound heating type is suitable for drying powdery and light materials.

　　At the same time, this model is also widely used for the thermal decomposition of materials containing crystal water and the high-temperature calcination of special materials. It is now more widely used in the chemical field, including metallurgy, minerals, ceramics, aquatic products, papermaking, food and other industries. Similarly, use excess steam to dry sludge, general garbage, etc.

Advantages of GS series rotary tube bundle dryer/cooler

　　● Large production capacity, continuous operation, high evaporation intensity. The evaporation intensity per unit volume of this machine is about 3 times that of a conventional heating tumble dryer.

　　● High thermal efficiency. It can reach 80%-90%.

　　● Fewer failures and low equipment maintenance costs.

　　● Low operating cost and simple operation.

　　● Long stay time. This adjustment can be arbitrarily changed according to the internal stay and speed.

　　● Dry at a certain temperature. For indirect heating, the temperature of the heating tube is set according to the steam pressure. This machine is also suitable for drying heat-sensitive materials, and the temperature of general products should be 15-50°C lower than the steam temperature.

　　● There is little dust in the exhaust. Because it can exhaust under high humidity of 80%-95%, the exhaust volume is small, the wind speed in the dryer is small, the amount of dust is small, and the investment in gas-solid separation equipment is small.

　　● The system can be operated in a closed condition.

Working principle of GS series rotary tube bundle dryer/cooler

　　The processed materials are transported to the tube bundle dryer through the feeder, and two to three layers of heating tubes are arranged on the inner circumference of the machine. The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal line. The material is added from the higher end. The heat carrier exchanges heat with the material through the heating tube from the lower end. The cylinder is equipped with a copy plate and a material level control device to make the material The movement rate and heat exchange time are precisely controlled to achieve the best heat exchange efficiency. The exhaust gas treatment part is equipped with a dust collector and an induced air device. The induced air generates a slight negative pressure in the equipment to ensure that the secondary steam can be quickly discharged to enhance the drying efficiency. The dust is captured by the dust collector to meet the environmental protection emission requirements. The final qualified products are discharged from the discharge box.
