Description of drawings
Accompanying drawing 1 is the schema of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment the structure of the utility model is further specified.
Shown in accompanying drawing 1, the utility model embodiment comprises: section's device 2 and device for purifying and treating tail gas 3 are fed in whirlwind-type sludge drier 1, storage.
Described storage drawing-in device 2 includes storage silo 21 and transfer roller 22, and described device for purifying and treating tail gas 3 includes steam separator 31, blower fan 32 and deodorizer 33.Have inlet mouth 34, air outlet 35 and condensation-water drain 36 on the steam separator 31.
Tail gas on whirlwind-type sludge drier outlet 4 is connected with the inlet mouth 34 of steam separator 31, and the air outlet 35 of steam separator 31 is connected with the inlet mouth 37 of blower fan 32, and the air outlet 38 of blower fan 32 is connected with deodorizer 33.
The discharge port 23 of the storage silo 21 in the described storage drawing-in device 2 links to each other with the opening for feed 24 of transfer roller 22.
Whirlwind-type sludge drier 1 comprises housing 11, is cylindric treater.Housing 11 set inside have material cavity 13; The cyclic motion that is used for the mud material; High-temperature medium chamber 14 internal recycle have high-temperature medium; Like saturation steam, thermal oil, warm air, the inwall of housing 11 is heated uniformly and effectively, and give material cavity 13 with thermal exchange through the conduction of heat of hot wall.Also comprise rotor 15 in the housing 11, rotor 15 links to each other with the motor 12 of device at housing 11 tops, and coaxial with housing 11, and the different positions of rotor 15 is provided with the blade 16 of different curves.Described blade 16 is the metal blade of different curves.Open motor 12, rotor 15 is high speed rotating under the driving of motor 12, drives blade 16, forms strong eddy current, and the cf-of generation impels the mud material evenly attached on material cavity 13 inwalls.
Mud material movement direction in the material cavity 3 is the discharge port 17 from opening for feed 18 to housing 11 tops of housing 11 bottoms; The high-temperature medium flow direction of high-temperature medium chamber 14 internal recycle is identical with the mud material movement direction in the material cavity 13, for doing screw motion from housing 11 bottoms to housing 11 tops.The motion in the same way on vertical surface of high-temperature medium and mud material, directing material travel forward along a direction, have avoided contacting of dried particle and overfire air stream, thereby have reduced the dust generation, gather, the superheated risk.
