Material mouth is connected to feeding device, and the discharge port of pipe bundle drier is connected to discharging device, and the waste vapour of the pipe bundle drier, which exports, to be connected
Logical treater for waste gas.The utility model structure is simple, easy to use, low cost, has a wide range of application, and can be good at reducing object
The temperature of raw steam, reduces energy consumption needed for material is dry, reduces waste steam exhausting, reaches energy-saving and emission-reduction purpose.But the device
The vacuum system of a set of steam that can draw water is needed, so that equipment investment is costly, running expense is high, and production efficiency of equipment is low.
Chinese patent notification number CN205897824U discloses a kind of direct connection pipe bundle drier, which is
Contact drier, steam, which by rotary joint enters intraductal heat transfer and becomes condensed water, to be discharged, the moisture in material outside pipe by
Thermal change is discharged at steam by dehumidifier blower, and material is transmitted to obtain shovel promotion in tube bank, uniformly drops down onto heating tube outer surface, and
Outlet material is pushed by shovel from input end and obtains drying.The direct connection pipe bundle drier, including pedestal, shell, transmission system and rotation
Adapter, shovel can adjust the angle according to the actual situation, and be equipped with steam control valve door, and dried material range is wide, moisture evaporation
Amount is big, and low energy consumption and can continuous production.But the device still uses steam heating method, steam condensation is condensation at work
Water discharge, a large amount of heat is lost therewith, and steam is generated by steam boiler, is secondary heat source, so traditional with steam
It is lower for the pipe bundle drier thermal efficiency of heat source.In addition because current steam boiler is most of also based on fire coal, steam is used
There is also the pressure of environmental protection.
