The lower section of shape dedusting mechanism, and the top in grey room is provided with wind-supplying mouth with being connected at the top of starter home on the side wall in grey room.
Preferably, waveform dedusting mechanism is made of dust-removal cloth-bag.
Preferably, the junction at the top of the top in grey room and starter home is provided with primary efficient filter screen.
Preferably, wind-supplying mouth be arranged at grey room top and wind-supplying mouth towards waveform dedusting mechanism.
Preferably, the both ends of air energy ajutage are respectively arranged at the bottom of heat pump hot-blast stove and the bottom of dryer.
Preferably, the cold air duct of the condensation end of heat pump hot-blast stove is connected with baking room.
In the above-mentioned technical solutions, the present invention ensure that dust will not be by setting baking room, starter home, grey room
Fly upward to one step；Secondly, the specific course of work is：First, heat pump hot-blast stove is started, the hot wind generated passes through air energy
Ajutage, which is delivered in baking room, dries grain, meanwhile, the hot wind with dust returned from baking room then passes through dust discharge exhaust pipe
It drains into grey room and is purified；Once for the hot wind with dust into ash charge room, it is laggard that hot wind then passes through waveform dedusting mechanism dedusting
One step into starter home to be preheated to heat pump hot-blast stove, so as to effectively achieve the effect of the recycling of heat；More attach most importance to
It wants, during heat recovery, can also play the role of dedusting；In addition, wind-supplying mouth can be that starter home supplement is new
Fresh air, ozone have carried out dedusting by waveform dedusting mechanism.Therefore the grain heat-drying center has excellent
Dedusting and waste heat recovery double effects.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
