Description
Technical field
The present invention relates to technical field of fertilizer production, particularly relate to a kind of when chemical fertilizer is carried out slurry-spraying pelletizing the tail cigarette of generation carry out the system of dedusting.
Background technology
In fertilizer process; by liquid material and solid feed after stirring pool mixes; form slurry to be sprayed by slurry-spraying pelletizing machine; then instantaneous hot-air seasoning pelletize; now produce a large amount of dust-laden tail cigarette; containing the less fertilizer of granularity in tail cigarette, direct discharge in atmosphere can serious environment pollution and cause the wasting of resources.
In existing fertilizer process, tail gas generally first gravitational dust collection, is then directly discharged in air after cyclone dust removal.Gravitational dust collection relies on action of gravity, utilizes the density variation of granule and gas, so as to relative motion occurs and settles.Gravitational settling is the simplest method isolating grit from air-flow, but can only remove the grit that granularity is more than 50 μm, and when air velocity is less, the effect of gravitational settling is just more apparent, and efficiency of dust collection is less than 50%.Cyclone dust removal utilizes centrifugal force produced by the dust-contained airflow rotated, and is separated by grit from gas, can reach 50%-80% for the granularity grit efficiency of dust collection more than 10 μm, but the granularity tiny grit removal efficiency less than 5 μm is relatively low.The grit that granularity is 3 μm is had the efficiency of dust collection of 80-85% by multicyclone dust collector in parallel.In tail gas, grit is not of uniform size, and wherein the granularity tiny grit less than or equal to 5 μm accounts for more than the 70% of total amount, and this just requires that the tiny grit less than or equal to 5 μm is had significantly high efficiency of dust collection by dust pelletizing system.
Dust-laden tail cigarette is entered casing from the gas approach of casing side by existing water curtain dedusting, and in casing, water curtain discharging device is sprayed water downwards; thus forming water curtain in casing, at this moment flue gas is from water curtain traverse, in process; grit can be absorbed by water curtain, thus the grit removed in dusty gas.Water curtain dedusting can remove the granularity grit less than 5 μm, but granularity grit removal efficiency below 1 μm is relatively low, and water curtain dedusting is using water as washings, need to the waste liquid after dedusting be recycled, and adds production cost, and causes the waste of resource.
Plasma dedusting utilizes extremely uneven electric field, form corona discharge, produce plasma, the a large amount of electronics wherein comprised and negative ions are under the effect of electric-force gradient, particulate pollutant generation inelastic collision with air, thus being attached to above, makes charged ion, under the effect of extra electric field power, collected by dust collecting electrode.Utilize a large amount of active particles in plasma that pollutant poisonous, harmful, difficult degradation are directly decomposed removal.Plasma dedusting can effectively be removed and clean flue dust, and granularity 0.1 μm of particles below and is floated on the harmful levels of pathogens in gas and all can be removed.
It is relatively low that existing dust pelletizing system also exists efficiency of dust collection in dust removal process, underuses tail cigarette waste heat and does not fully reclaim grit, and causing the shortcomings such as secondary pollution.
Summary of the invention
The present invention designed and developed a kind of when chemical fertilizer is carried out slurry-spraying pelletizing the tail cigarette of generation carry out the system of dedusting.After the present invention adopts two stage cyclone duster parallels, then through screen collector and plasma cleaner unit dedusting, efficiency of dust collection is high, and after cyclone dust removal, primary neat stress and cold liquid material carry out heat exchange by heat exchanger, make liquid material acquisition tail cigarette waste heat, and water curtain dedusting is using liquid material as washings, without the waste liquid after washing is processed again, the waste back-cycling after the dust reclaimed after cyclone dust removal and water curtain dedusting is carried out slurry-spraying pelletizing again after stirring pool.The present invention takes full advantage of tail cigarette waste heat, and has reclaimed the grit in tail cigarette, and efficiency of dust collection can reach 99%.
