Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cross-sectional schematic of Fig. 1.

The specific embodiment:

As shown in Figure 1, the utility model comprises screw(-type) feeder 1, burner 2, rotation inner furnace body 3, three oil burners 4,5,6, outside fire resistant heat preserving body of heater 7, stove tail 8, activating apparatus 9, tail gas jetting type discharger 10 and bases 11, wherein, screw(-type) feeder 1, burner 2 and stove tail 8 are separately fixed on the base 11, and these stove tail 8 bottoms are provided with carbon collecting bucket 81; Outside fire resistant heat preserving body of heater 7 is fixed on the base 11 by support roller 71 and support 72 thereof; Three oil burners 4,5,6 are separately positioned on the outside fire resistant heat preserving body of heater 7, and these fire resistant heat preserving body of heater 7 inside, outside are provided with rotation inner furnace body 3, and this rotation inner furnace body 3 links to each other with motor 32 by gear wheel 31, and motor fixes by support 33 and base 11; Activating apparatus 9 links to each other with the afterbody of rotation inner furnace body 3, and tail gas jetting type discharger 10 is arranged on the burner, and the steam that makes the beginning dry run produce is effectively got rid of; Screw(-type) feeder 1 will treat that by burner regenerated carbon sends in the rotation in the stove 3, by a plurality of burners 4,5,6 provide heat energy between outside fire resistant heat preserving body of heater 7 and rotation inner furnace body 3, a plurality of burners complement each other and guarantee the stable of regenerative process fire box temperature, burned flame sprays between outside fire resistant heat preserving body of heater 7 and the interior stove interior 3 of rotation, it is temperature required to reach each section by automatic temperature-adjusting control, automatically the drying of active carbon regeneration is finished in control, high temperature carbonization and activate three processes, final charcoal is got rid of from stove tail 8, guaranteed the regenerability of active carbon, the process Automatic Control, the regeneration temperature precise control;

Outside fire resistant heat preserving body of heater 7 separates with the rotation inner furnace body 3 of steel, and the burning between is finished; Be provided with blade 34 in this rotation inner furnace body, blade 34 is along rotating the equidistant installation of inner furnace body inwall circumferencial direction in the rotation inner furnace body, rotation inner furnace body inclination certain angle, active carbon and hot blast contact area had both effectively been guaranteed, make active carbon again under the gyroscopic action of blade 34 that tilts and rotation inner furnace body 3, flow to stove tail 8 by inlet, finished charcoal; Burner is done thermal source with heavy oil or diesel oil, and thermal efficiency height is easy to control; Activating apparatus 9 makes active carbon open the activated water that magnetic valve feeds certain flow when the body of heater afterbody reaches uniform temperature by automatic control box control, thereby finishes the activation process of charcoal; Automatic control box control automatically advances charcoal, goes out charcoal, by temperature survey transmission control, and the unlatching of control burner, thereby the temperature of control burner hearth, it is temperature required in each stage to reach active carbon.

During use, after fire box temperature preheating uniform temperature, screw(-type) feeder 1 will be with certain speed by burner 2, will treat that regenerated carbon sends into rotation inner furnace body 3, rotation inner furnace body 3 is with speed rotation very slowly, and the calory burning of regulating multistage burner 4,5,6 makes it to mate with production capacity; Because rotation inner furnace body 3 inclination certain angles, active carbon can slowly flow to tail end from front end; Active carbon is a drying stage when just entering rotation inner furnace body 3, the water evaporates of absorption in the activated carbon granule, also volatilization thereupon of the lower boiling organic matter of part simultaneously, enter the roasting stage then, or title carbonation stage, the grain charcoal is heated and is warming up to 150～700 ℃, different organic matters raise with temperature, respectively with volatilization, decompose, carbonization, the form of oxidation, eliminate from the matrix of active carbon, this process is the stage of longer duration, enter activation stage subsequently, organic matter has the considerable part carbide to remain in the activated carbon capillary behind high temperature cabonization, this moment, carbide needed to carry out gasification reaction with oxidizing gas such as water vapours, made residual carbide be gasificated into CO at higher temperature ₂, gases such as CO; Make micropore surface obtain cleaning, recover its absorption property, thereby finish the regeneration of charcoal; Activation process betides the end of rotation inner furnace body 3, flows into stove tail 8 then, discharges from carbon outlet port; Drying, roasting, activation three processes of regeneration provide heat energy by a plurality of burners 4,5,6, control each section temperature by automatic control box.
