Method of selection for drying equipment

When selecting the drying mechanical equipment, we must consider the auxiliary equipment. This ` because the drying system is made up of drying mechanical equipment and auxiliary equipment. Auxiliary equipment is also the key to choosing whether the link is appropriate. Under normal circumstances, the drying system is mainly composed of ventilation equipment, heating equipment, host machine (drying equipment), gas-solid separation equipment, feeding equipment, etc.

The rising energy costs and pollution restrictions, working conditions and safe operation directly affect the drying equipment design and selection. These design factors (especially the design of suspension dryers, such as spray, Flash, and fluidized bed dryers) that fully discuss the various types of drying machinery in the selection stage. Sometimes, different materials and different occasions can dry the treatment device, and these factors must be taken into account at the design stage.

For gases, the drying device can cause pollution due to dust removal. In some places, even steam is not allowed. The general requirement is that if the exhaust concentration is less than 20 ~ 50mg / Nm 3 dust, they may establish an efficient dust collector. Importantly, under certain conditions, it is suitable for the drying of coarse particles. On the other hand, the larger particles have a longer drying time. In the dry powder materials in the dust and gas purification commonly used cyclone separator aggregation, bag filter, electrostatic precipitator, and other forms, such as paste, paper and other materials dry, only in the convection of dry material dust occurs. In order to eliminate harmful gas pollution, people can use it through absorption, adsorption or incineration.
