Description

Combustion type granular activated carbon regeneration rotary kiln

Technical field

The utility model relates to a kind of active carbon reclaim equiment, particularly a kind of combustion type granular activated carbon regeneration rotary kiln.

Background technology

At present, granular active carbon reclaim equiment, particularly rotary kiln type reclaim equiment adopt the silicon carbon rod more, and the thermal efficiency is low, and the power consumption height need be improved.

The utility model content

The purpose of this utility model is to provide a kind of combustion type granular activated carbon regeneration rotary kiln, has solved problems such as the active carbon reclaim equiment thermal efficiency commonly used is low, power consumption height.

The technical solution of the utility model is: comprise screw(-type) feeder, burner, the regeneration rotating furnace body, gas burner, the stove tail, the activation facility, tail gas jetting type discharger and automatic control box, wherein, screw(-type) feeder, burner and stove tail are separately fixed on the base, regeneration rotating furnace body front portion is fixed on the base by support roller and support thereof, being provided with gear wheel at its rear portion links to each other with motor, motor is fixed on the base by support, two gas burners link to each other with afterbody with the head of regeneration rotating furnace body respectively, the activation facility links to each other with the afterbody of this regeneration rotating furnace body, and tail gas shooting streaming discharger is arranged on the burner.The skin of said regeneration rotating furnace body is the steel urceolus, and the middle level is an insulation material, and internal layer is a refractory brick, and this steel urceolus and insulation material are one; Regeneration rotating furnace body inclination certain angle; The bottom of stove tail is provided with a carbon collecting bucket; Open the activated water that magnetic valve feeds certain flow when the activation facility arrives uniform temperature by automatic control box control regeneration rotating furnace body afterbody, thereby finish the activation process of charcoal.

Advantage of the present utility model is: simple in structure, easy to operate, and the automaticity height, the active carbon regeneration temperature is stable, and high temperature is long in the burner hearth time of staying, and regeneration back active carbon activity is good; With the combustion gas is thermal source, and combustion heat value height, burned flame directly spray into burner hearth and directly contact with active carbon, thermal efficiency height, and the carbon dioxide that burning produces also can promote the activating and regenerating of charcoal; Heat energy utilization is good, and energy consumption is low, and is practical.

Description of drawings:

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

The specific embodiment:

As shown in drawings, the utility model comprises screw(-type) feeder 1, burner 2, regeneration rotating furnace body 3, gas burner 4,5, stove tail 6, activation facility 7, tail gas jetting type discharger 8, base 9 and automatic control box, wherein, screw(-type) feeder 1, burner 2 and stove tail 6 are separately fixed on the base, and the bottom of this stove tail 6 is provided with a carbon collecting bucket 61; Regeneration rotating furnace body 3 front portions are fixed on the base 9 by support roller 31 and support 32 thereof, are provided with gear wheel 36 at its rear portion and link to each other with motor 37, and motor 37 fixes by support 38 and base 9; The skin of regeneration rotating furnace body 3 is a steel urceolus 33, and the middle level is an insulation material 34, and internal layer is a refractory brick 35, and this steel urceolus 33 is an one with insulation material 34; Regeneration rotating furnace body 3 inclination certain angles had both guaranteed time of staying of charcoal to have finished charcoal again; Two gas burners 4,5 link to each other with afterbody with the head of regeneration rotating furnace body 3 respectively, gas burner 4 provides dry required heat energy, gas burner 5 provides high temperature carbonization required heat energy, both complement each other and guarantee the stable of regenerative process fire box temperature, burner is a thermal source with fuel gas such as natural gas or liquefied gas, and burned flame directly sprays into burner hearth, directly contacts with active carbon, thermal efficiency height, the carbon dioxide that burning produces also can promote the regeneration of charcoal; Activation facility 7 links to each other with the afterbody of this regeneration rotating furnace body 3, opens the activated water that magnetic valve feeds certain flow when arriving uniform temperature by automatic control box control regeneration rotating furnace body 3 afterbodys, thereby finishes the activation process of charcoal; Automatic control box control automatically advances charcoal, goes out charcoal, by temperature survey transmission control, thus the temperature of the unlatching control burner hearth of control burner, it is temperature required in each stage to reach active carbon; Tail gas shooting streaming discharger 8 is arranged on the burner 2, and the tail gas such as steam that make the beginning dry run produce are effectively got rid of from outlet port 81.

During use, after fire box temperature preheating uniform temperature, screw(-type) feeder will will treat that by burner regenerated carbon sends into body of heater with certain speed, and body of heater is with speed rotation very slowly, and the calory burning of regulating burner 4,5 makes with production capacity and mates; Because the tilting furnace certain angle, active carbon can slowly flow to tail end from front end, and active carbon is drying stage when just entering body of heater, 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 claim carbonation stage; The grain charcoal is heated and is warming up to 150～700 ℃; Different organic matters raise with temperature, respectively with the form of volatilization, decomposition, carbonization, 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 gas reaction with oxidizing gas such as water vapour, carbon dioxide, 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 body of heater, flows into the stove tail then, discharges from carbon outlet port; Drying, roasting, activation three processes of regeneration provide heat energy by the two-stage combustion device, control each section temperature by automatic control control case.
