Background technology：
, it is necessary to which calcium carbide progress is repeatedly crushed stage by stage in the production process of lime nitrogen chemical fertilizer, until below 80 mesh
Powdery can just input reacting furnace and produce lime nitrogen finished product for nitridation reaction, to the size of calcium carbide particle in the process
Control can not accomplish that completely accurately existing 80 mesh sized particles in broken material, there is also take measurements less than 80 mesh greatly
Particle, its reaction speed is different under different particle sizes, while fine and closely woven dirt shape material is being passed there are conglomeration sticking problem
In the continuous production type sedimentation furnace of system, the material of conglomeration is much smaller than the particulate matter of 80 mesh by the speed of reaction chamber and size
Material is slower by reaction chamber speed, causes the product nitridation obtained after reaction uneven, influences product quality uniformity.
The content of the invention：
In consideration of it, different sized particles can be settled to path separation it is necessary to design one kind, pass through different size materials
Nitriding furnace conversion zone time convergent new-type sedimentation furnace.
Spiral inner fin tube formula sedimentation furnace, including：Tubular type furnace chamber, furnace chamber helical fin, lower sedimentation chamber, upper sedimentation chamber, rotation
Wind separator, cyclone separator gas check, furnace chamber air inlet, lower sedimentation chamber air inlet pipe, airtight feed inlet and airtight discharge port；
Wherein tubular type furnace chamber is circular tube shaped, and the upper end connects upper sedimentation chamber, and the lower sedimentation chamber of lower end connection, upper sedimentation chamber is fusiform, is pushed up
Cyclone separator is installed in portion, is connected at upper sedimentation chamber top convergence with cyclone separator air inlet, cyclone separator ash-collecting port is stretched
Enter in upper sedimentation chamber and cyclone separator gas check be installed, cyclone separator gas check for outer rim be bonded to each other to turning double
Wheel, is bonded with cyclone separator ash-collecting port, and airtight feed inlet is mounted on upper sedimentation chamber side-walls, the convergence of lower sedimentation bottom of chamber portion, bottom
End is equipped with airtight discharge port.
Furnace chamber helical fin is mounted on tube furnace intracavitary, and furnace chamber helical fin outer rim is connected sealing with tube furnace cavity wall,
Furnace chamber helical fin inner edge opposed outer edge tilts down, and furnace chamber air inlet is mounted on furnace chamber helical fin bottom and is directed toward along furnace chamber
The direction that helical fin rises；Lower sedimentation chamber air inlet pipe is mounted on lower sedimentation chamber side wall.
During work, furnace chamber air inlet is blown into nitrogen along furnace chamber helical fin direction and forms spiralling eddy flow, and passes through
Velocity pressure difference reduces lower sedimentation cavity pressure, and tube furnace intracavitary is made to form furnace chamber helical fin regional gas stream spiral, in
The gas circuit that vertically declines of air-flow at the access of centre, while under the effect of eddy flow centrifugal force, particle is larger or the material that is adhered be more easy into
Enter furnace chamber helical fin region and rise back sedimentation chamber so as to blow, particle is larger or the material that is adhered passes through tubular type furnace chamber so as to postpone
Average time, make the nitridation of material tend to be uniform；Disperse the upper in vivo material of sedimentation chamber gas upper sedimentation chamber spinning
Hammer shape expansion area is slowed down by gas settles and is again introduced into the participation reaction of tubular type furnace chamber, a small amount of material continued with gas uplink
It is separated by cyclone separator, is squeezed through cyclone separator gas check turning two-wheel, upper sedimentation is discharged into again to be adhered state
Intracavitary；Lower sedimentation chamber air inlet pipe adjusts the air-flow decrease speed of central corridor in tubular type furnace chamber for being pressurized in downward sedimentation chamber.
Airtight feed inlet is the airtight feed inlet of dual gate, there is adapter cavity between front and rear flashboard, and material is in nitrogen atmosphere during charging
Under gradually by it is different when the front and rear flashboard opened prevent gas injection in upper sedimentation chamber；Airtight discharge port unloads for dual gate is airtight
Material mouth, there is adapter cavity between front and rear flashboard, during discharging material gradually by it is different when the front and rear flashboard opened prevent lower sedimentation intracavitary
Gas injection.
Preferably, the design further includes bag filter, and cyclone separator is provided in parallel two, each cyclonic separation
Respectively one bag filter of installation, the design can further prevent that material is heavy with exhaust discharge to device exhaust pipe by bag filter
Stove drops, and two cyclone separators can realize the uninterrupted operation of equipment by way of alternately blowback.
The present invention realizes material particles size, the differentiation gas for being adhered state by tube furnace intracavitary helical fin structure
Road processing procedure effectively increases material by the nitridation uniformity coefficient after nitriding furnace, improves the uniformity of product quality.
