Start air-introduced machine, air-introduced machine extracts carbon black tail gas and enters dedusting tower bottom by heat exchanger tube, and cooling water circulation is logical
Heat of the road I in the cyclic absorption carbon black tail gas in cooling duct 2, cools down to carbon black tail gas.Charcoal black tail after cooling
Gas enters gas wash tower, and moves from bottom to top in gas wash tower.
Start motor, the rotation of motor driven negative pressure fan, negative pressure fan has upward extraction force, charcoal black tail to carbon black tail gas
Gas successively passes through spray section, fillter section and dryer section, and the cooling water that spray section sprays is cooling to carbon black tail gas further progress,
The dust impurity contained in carbon black tail gas is washed away simultaneously, the charcoal for being equivalent to and carbon black tail gas being cleaned, but move upwards
Inevitably can also sweep along impurity in black tail gas, spray waterpipe 5 is grid-shaped, then spray waterpipe 5 be equivalent to form one it is netted
Strainer can then carry out preliminary filtering by netted spray waterpipe 5 when carbon black tail gas moves upwards, while it is also possible that
Carbon black tail gas tentatively scatter, so that the slave multiple directions of carbon black tail gas dispersion uniformly pass through the first filter plate 7, avoids big
It measures carbon black tail gas and concentrates and somewhere pass through the first filter plate 7, it is easier to so that the first filter plate 7 at this blocks.
When the cooling water of dedusting tower bottom is more, cooling water accumulation is easy to influence the entrance of tail gas, can open valve,
By the cooling water discharge in gas wash tower.In addition, can be set between controller control valve door to reduce the operation difficulty of operator
It has a rest opening and closing, i.e., cooling water intermittence is discharged, and the cooling water of discharge is come back to by cooling water pipe to be participated in recycling in heat exchanger 17.
Carbon black tail gas continues through the first filter plate 7 and the second further filtering of filter plate 8 of fillter section, and carbon black tail gas is through filtering
After flow to dryer section, on the one hand negative pressure fan rotation makes the carbon black tail gas on gas wash tower top scatter, so that carbon black tail gas
It is moved to close to dryer section inner wall direction, so that the moisture contained in carbon black tail gas is absorbed by water absorption layer, guarantees drying
Uniformity.Meanwhile the shaft 12 of negative pressure fan is when rotating, shaft 12 and reciprocating screw rod 10 form screw pair, under reciprocating screw rod 10
End is fixed on the second filter plate 8, can not be rotated by 8 position-limiting action of the second filter plate, and shaft 12 drives 10 vertical motion of reciprocating screw rod,
And then realize sliding up and down for the second filter plate 8.For carbon black tail gas after the first filter plate 7, carbon black pellet may be adhered to first
Filter opening is even blocked in the filter opening of filter plate 7, and cleaning of stopping is needed after long-time use.And the second filter plate 8 drives and glides on thimble 9
Dynamic, thimble 9 can be inserted into the filter opening of the first filter plate 7, and the carbon black pellet being adhered in filter opening is pushed down.
The carbon black tail gas being discharged at the top of from gas wash tower enters the fuel gas inlet of jet dynamic control 16, in jet dynamic control

18, processing is filtered to tail gas by dust-removal cloth-bag 18.Meanwhile being rotated by shaft 12 and turntable 19 is driven to rotate, due to removing
Dirt cloth bag 18 is flexible material, and when turntable 19 drives dust-removal cloth-bag 18 to rotate, the revolving speed of 18 top and the bottom of dust-removal cloth-bag is different, is removed
The whole rotating effect that distortion is presented of dirt cloth bag 18.Meanwhile dust-removal cloth-bag 18 relative to reciprocating screw rod 10 smooth section rotation when,
The rotation of shaft 12 drives reciprocating screw rod 10 to move up and down, and reciprocating screw rod 10 drives position-arresting disk 21 to move up and down, and position-arresting disk 21 drives
The bottom of dust-removal cloth-bag 18 vibrates up and down, and shakes off to be adhered to the carbon black pellet on dust-removal cloth-bag 18.
What has been described above is only an embodiment of the present invention, and the common sense such as well known specific structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these also should be considered as protection scope of the present invention, these all will not influence what the present invention was implemented
Effect and patent practicability.
