Background technology
During chemical fertilizer production, producing a large amount of dust-laden tail cigarette during slurry-spraying pelletizing, tail cigarette temperature is higher, and contains
Having a large amount of solid particle, direct discharge in atmosphere can serious environment pollution and cause the wasting of resources.
Cyclone dust extractor utilizes centrifugal force produced by the dust-contained airflow rotated, and is separated by grit from gas
Out, more than the grit efficiency of dust collection of 10 μm, 50%-80% be can reach for granularity, but granularity is less than
The tiny grit removal efficiency of 5 μm is relatively low.
The dust-laden tail cigarette gas approach from casing side is entered casing, in casing, water curtain by water curtain dedusting
Discharging device is sprayed water downwards, thus forms water curtain in casing, and at this moment flue gas passes from water curtain, is passing
During, grit can be absorbed by water curtain, thus removes the grit in dusty gas.Water curtain dedusting can remove
Granularity is less than the grit of 5 μm.
It is relatively low that existing dust pelletizing system also exists efficiency of dust collection, the washings large usage quantity of screen collector,
Equipment easily blocks, and underuses tail cigarette waste heat and causes the problems such as the wasting of resources.
