There is the second tracheae, the second tracheae is arranged at 3rd/2/3rds~tetra- of drying tower.
Design of the present utility model is：Airflow hole on airflow-distribution board is set in echelon or back taper, lifts gas
The flow velocity of stream, it can be ensured that the air-flow come out from the first tracheae is reached at the second tracheae, the air-flow that can be come out with the second tracheae
Mixing is referred to as turbulent air flow, and the turbulent air flow of formation can fully dispel nano-powder, avoid nano-powder from being adhered to drying tower
Inwall on.
When airflow hole is trapezoidal, airflow hole is that upper bottom is more than the trapezoidal of bottom.The setting of this trapezium structure can carry
The speed of air-flow is risen, prevents that opening position of the air-flow of the first tracheae ejection where the second tracheae is reached from largely being subtracted
It is weak.
Airflow-distribution board is back-off umbrella shape.The air-flow that the setting of back-off umbrella shape can be given at the first tracheae out is more
The upper space of back-off umbrella shape is gathered in, the flow velocity of air-flow from airflow-distribution board out can be lifted.
Being in charge of for multiple connections is provided with first tracheae, is in charge of the top for being evenly distributed on airflow-distribution board.
Dried at second tracheae on inner wall of tower and be provided with annular groove.The setting of ring shaped slot can change to be come out at the second tracheae
Air flow direction so that the air-flow at the second tracheae and at the first tracheae meets at horizontal and vertical, intersects so that air-flow
One way or another dissipates, so as to avoid nano powder from being adhered on inner wall of tower is dried.
The utility model compared with prior art, has the following advantages and advantages：
The utility model can prevent nano material to be bonded on the inwall of drying tower, reduce nano material in preparation process
Loss.
