By the above-mentioned explanation that the utility model is put, the utility model is put to compare with original drying equipment has following outstanding feature:
1, electromagnetic induction heating: by homemade electromagnetic induction conducting slip ring, the variable-frequency power sources operating frequency is controlled between the 500-4500Hz, variable-frequency power sources is sent in the blade spiral hollow axle of rotation and is heated.
2, efficient energy-saving: electromagnetic induction coil is owing to directly being wound in the blade hollow shaft, coil produces the high-frequency alternating magnetic field, makes the induced-current of blade hollow shaft generation same frequency, the rapid self-heating of electromagnetism blade hollow shaft, by the ladder Heat preservation, reach very soon required technological temperature.0-700 adjusts arbitrarily with dried material moisture is different.Adopt to dodge that a evaporate to dryness is dry, the drying mode of b fluidized drying, c hot-blast stove, although be directly heating, but temperature of charge is extremely inhomogeneous, dust dedusting difficulty is large, heat utilization rate is low, and the d box-type drying of steam drying, the vacuum drying of e bipyramid rotary are to be heating top by boiler, and hot pipe conducting efficient is extremely low, time is long, the uncontrollable temperature of technique.
3, drying time short, efficient is high owing to selecting electromagnetic induction heating, heating-up temperature 0-700 can make material reach in a short period of time homogeneous heating according to material technique, has greatly shortened drying time.Can make maximum production.
4, constant product quality: many warm areas electromagnetism blade drying device is adjusted temperature range according to the dry materials technology quality index wide because technological temperature can realize that auto-manual arbitrarily adjusts at 0-700, and temperature-controlled precision is high.Because electromagnetism blade drying device serviceability temperature can reach 700, the grease in the cleavable decomposing materials, desulfurization rapidly, depickling, reagent removal, low-temperature bake etc., improving material rate of drying and credit rating.No matter be directly to act as a fuel or coal changes into steam with coal, the technique temperature control lags behind, and the random bake out temperature of material is unstable, and the dry materials difficult quality is guaranteed.
5, the dried material scope is wide: use Electromagnetic Heating, can process heat sensitive material, can process again the material that needs high-temperature process.But get final product also intermittent operation of continued operation, can in a lot of fields, use.
6, automaticity is high: feed arrangement is delivered directly to material in the w type blade drying equipment loading hopper, make material fully carry stirring by the worm drive agitating device, in effective improving material rate of drying and quality, front charging or rear discharging all are that the machine automatization gasifying device need not human assistance, and other drying equipment all needs manually-operated, and labor intensity of operating staff is large.
7, environmental protection: electromagnetism blade drying device heating source is that electric energy is converted into heat energy, heat utilization rate 98% is absorbed transpiring moisture by material, heat-energy losses is few, operating ambient temperature is low, and the dry run of material is all finished in closed container, can not cause material dust to fly upward, can not affect the healthy of operating personnel because of operating ambient temperature and airborne dust pollution.No matter coal directly heats or converts steam to, because there are inevitable technical problem in equipment and this body structure of facility, heat utilization rate is low, and heat-energy losses is large, and operating ambient temperature is high, and on-the-spot dust pollution is large, and the discharging coal smoke has a strong impact on environment.
8, operating cost is low: no matter to metal, smelting, coloured industry, low-temperature bake, environmental protection industry (epi), chemical industry.With hundred tons of meterings, adopt many warm areas electromagnetism blade drying device, the drying mode that production technology and traditional abc directly burn with coal, and the economic performance of de take steam as drying mode is relatively:
Following table is without under the drying mode, the economic performance comparison sheet take the same material as raw material:
| Drying device | The direct burnup of coal | Boiler forms steam | Many warm areas electromagnetism blade drying device |
| Device type | abc | de | The electromagnetism blade is dry |
| Operating efficiency | 70% | 50%-60% | 98% |
| Water evaporation quantity | 97% | 90% | 99.5% |
| Operating cost | 123 yuan | 165 yuan | 87 yuan |
| Equipment investment | 55 yuan | 67 |
48 yuan |
650 yuan/tons of the average coal prices in the above whole nation, 0.7 yuan of electricity price/degree, required unit costs figure when moisture is dried to 1% from 30%.
