Abstract
The invention relates to a method for continuous regeneration of powdered activated carbon, which adopts a fluidzed drying furnace, a fluidzed activation furnace, and an efficient separator to reactivate the inactivated powdered activated carbon. A process system of the invention comprises the following equipment: a rotary drying furnace 1 with sand, a horizontal type pneumatic cyclotron activation furnace 3, efficient cyclone separators 2 and 6, a scrubber tower 4 and a fan 5. Compared with a smoulder furnace (activation pot method) method, a Bratpfannen method, a slotted hearth furnace method and a molding pelleting and activation method, the method has the characteristics of low energy consumption, high yield, no pollution, excellent product quality and low labour intensity.
Description
Technical field the invention belongs to the regeneration of active carbon
Background technology
After powdered activated carbon was used, promptly losing activity became useless powdered carbon.Be to abandon or act as a fuel to deactivated powdered carbon treating method in early days, this has not only wasted resource and has also polluted environment.The back is under the pressure of situation and interests, and the powdered carbon that will give up is collected and regenerated.
Domestic main renovation process has: the oven process of smouldering, dull and stereotyped oven process, slot type oven process, molding, granulating activation method (vertical heater) etc.These methods are all carried out Batch Process, and energy consumption height, yield are low, contaminated environment, poor product quality, and labour intensity is big.
External main adopt vertical fluidized bed furnace, device structure is simple, carry out continuously and produce, and tail gas is collected the powdered carbon that burns till through the water spray cooling with sack cleaner.Perhaps directly collect with wet scrubber, the product that obtains is pulpous state, and heat energy is underused.
For overcoming the shortcoming of above method, the present invention adopts the two-section flowing bed activating process, obtains better effects in useless powdered carbon regeneration.The present invention adopts continuous process system, and the thermal source of drying oven is the flue gas of activation furnace.Heat energy utilization is abundant, good quality of product, yield height, pollution-free, labour intensity is low.
Summary of the invention
Description of drawings, production system of the present invention is made up of following equipment: the rotary drying stove 1 of band sand, the horizontal strength activation furnace 3 that circles round, high-efficiency cyclone separator 2 and high-efficiency cyclone separator 6, aeration tower 4 and blower fan 5.
Production technology of the present invention is: moisture 70% useless powdered carbon input rotary drying stove 1 carries out drying, and thermal source is from the exhaust (700 ℃) of cyclone separator 6; Dry powdered carbon enters cyclone separator 2 with tail gas, separates the powdered carbon input strength convolution activation furnace 3 that obtains, and finishes activation at 900 ℃; The powdered carbon of activity recovery is collected in high-efficiency cyclone separator 6; The high-temperature gas input rotary drying stove 1 that cyclone separator 6 is discharged; Drying oven tail gas is discharged through cyclone separator 2, is transported to cyclone separator 2 and cyclone separator 6 with blower fan 5 superchargings after the water spray cooling, and residual exhaust is emptying. So operation continuously processes qualified powdered activated carbon product, and takes full advantage of heat energy.
Production method of the present invention is compared with smouldering furnace, dull and stereotyped oven process, slot type oven process, molding, granulating activation method (vertical heater) etc., has good quality of product, energy consumption is low, yield is high, pollution-free, characteristics that labour intensity is low.

Moisture 70% the phosphoric acid method powdery sugar charcoal that gives up is imported fluid bed activation furnace of the present invention, drying, activation, and obtaining the methylene blue decolorizing ability is the 9ml activated carbon product, yield 75% (in the over dry raw material).The contrast flattening oven, the useless sugar charcoal of moisture 70% the phosphoric acid method powdery of regenerating, obtaining the methylene blue decolorizing ability is the 4.5ml activated carbon product, yield 40% (in the over dry raw material).
Embodiment two
Moisture 70% useless monosodium glutamate tailored flour shaped activated carbon is imported fluid bed activation furnace of the present invention, drying, activation, and obtaining the methylene blue decolorizing ability is the 12ml activated carbon product, yield 70% (in the over dry raw material).The contrast flattening oven, moisture 70% the useless monosodium glutamate tailored flour shaped activated carbon of regenerating, obtaining the methylene blue decolorizing ability is the 8.5ml activated carbon product, yield 40% (in the over dry raw material).
Embodiment three
Moisture 70% useless glycine powdered activated carbon, input two-section flowing bed activation furnace of the present invention after the preliminary treatment, drying, activation, obtaining the methylene blue decolorizing ability is the 12ml activated carbon product, yield 85% (in the over dry raw material).The contrast flattening oven, pretreated moisture 70% the useless glycine powdered activated carbon of regenerating, obtaining the methylene blue decolorizing ability is the 8.5ml activated carbon product, yield 50% (in the over dry raw material).
