Introduction to dryers ① Classification of dryers
Dryers include belt drying, drum drying, box drying, tower drying and other modes. The heat source is coal. During the drying process of materials such as electricity and gas, there are hot air flow type and radiation type. Hot air drum drying is a hot air flow moving forward from the tail, fully contacting the material, and making full use of the heat transfer through heat conduction, convection, radiation, and direct transfer of heat energy. The material is fed so that the moisture of the material is continuously evaporated in the cylinder. The air induction device at the material inlet draws out a large amount of water and wet air flow to prevent secondary pollution caused by dust discharge. The internal spiral stirring is used to sweep away the lifting plate and promote the movement of the material. , complete the entire drying process by countercurrent conduction dehumidification to avoid reducing repeated drying procedures.
② Features of the dryer
High drying intensity
Since the material is highly dispersed in the air flow, the entire surface of the particles is actively used as an effective area for drying
.
Short drying time.
The air flow dryer has a simple structure, small footprint, and is easy to build and maintain.
Large processing capacity and high thermal efficiency. When drying unbound water, the thermal efficiency can reach %.
The dryer achieves zero horizontal thrust, which greatly reduces the wear of the supporting wheel, and the cylinder runs smoothly and reliably
The dryer adopts an aligning supporting wheel device, so that the cooperation between the supporting wheel and the rolling ring is always in perfect alignment. Linear contact, thus greatly reducing wear and power loss.
③ Product use
Frequently asked questions
In the process of production and sales of dryers, there are some common problems, such as the raw materials not drying at one time and the raw materials in the dryer catching fire. question.
The raw materials cannot be dried at one time
Reason: The dryer is too small, the wind network, the wind pressure and flow calculation are incorrect, and the dryer is used improperly.
Solution:
Increase the temperature of the dryer, but this method can easily cause fire in the dryer. The best way is to replace or re-modify the drying equipment and ask the dryer manufacturer to recalculate the air pressure and flow rate. Then provide a design change plan based on the actual situation, negotiate with the dryer manufacturer, obtain the equipment manual, and learn the correct use method.
The raw materials in the dryer caught fire
Reason: The dryer equipment was used improperly. The dryer equipment was too small to achieve the drying effect and forced heating caused a fire. There was a problem with the design principle of the dryer equipment
