Embodiment
This equipment designs according to the form described in utility model content completely in its embodiment.To be described further at this.See figures.1.and.2, " metal solid waste material heat treatment apparatus " is formed primarily of the round tube type rotary kiln 10 forming sealed furnace firing chamber, the turning axle of rotary kiln is in tilted layout from the metal solid waste material input terminus process material output terminal to the right in left side, the two ends of round tube type rotary kiln 10 connect input terminus non-rotating sealing member 22 and output terminal non-rotating sealing member 24, the space, firing chamber of output terminal non-rotating sealing member 24 front end is extended to from hot gas inlet 14 with the coaxial center hot gas path 32 of round tube type rotary kiln 10, namely the upper space of the discharge end relief outlet 28 of round tube type rotary kiln 10 is stretched to, thus form the tubular furnace charge passage be made up of round tube type rotary kiln 10 outer wall and center hot gas path 32.
Metal solid waste material to enter in the tubular furnace charge passage round tube type rotary kiln 10 through open-ended inclined feeding pipe 26 from hopper 20, and by this furnace charge passage, discharged from discharge end relief outlet 28 by after the reverse hot gas heating passed through, fall into afterwards on lift and conveyer 30.
To be derived by hot-blast conduit 36 from the lower end of the adjacent afterburner 37 of input terminus non-rotating sealing member 22 for the heating hot gas of preheating and control temperature and be fed in center hot gas path 32 through hot gas inlet 14.
In order to prevent numerous sealing position leakage pollution gas, in round tube type rotary kiln 10, the pressure-controlling of flowing gas is negative pressure.
In round tube type rotary kiln 10, the negative pressure of flowing gas is the centrifugal blower 38 draft effect by being positioned at input terminus non-rotating sealing member 22 top exhanst gas outlet, negative pressure is formed on the top being attached thereto logical input terminus non-rotating sealing member 22, the air outlet of centrifugal blower 38 is connected with smoke-uptake 40 by pipeline, and smoke-uptake 40 is communicated with the upper end of afterburner 37 again.
The circulation hot gas entered in round tube type rotary kiln 10 does not directly contact with metal solid waste material at first, is introduced in center hot gas path 32 and conducts heat; Then, return to the space of input terminus non-rotating sealing member 22 from output terminal non-rotating closure mechanism 24 space, sail against the current with the direction that the metal solid waste material direction of motion in round tube type rotary kiln 10 is contrary, direct heating metal solid waste material; Finally, the draft of centrifugal blower 38 is utilized to be drained into the upper end of afterburner 37 through smoke-uptake 40.
Afterburner 37 can use gas with various fuel and dissimilar burner.After-burner 42 design temperature of afterburner 37 must higher than the temperature in round tube type rotary kiln 10, with reach make to add heat waste floating coating composition and the temperature of other pollutant component in after-burner 42 under carry out chemical reaction and obtain pyrolysis with the object of Transformatin.The combustion gases of discharging bottom after-burner 42, turned back to the upper end of afterburner 37 by centrifugal blower 38 and smoke-uptake 40 after round tube type rotary kiln 10, a part wherein can be recycled, major part after hot gas heat exchange cooler 47 cooling heat transferring be connected with the upper end of afterburner 37, then is delivered to after pollution control device 50 processes through lateral 46 and is discharged through secondary smoke-uptake 52.
Metal solid waste material is advanced to the main region of round tube type rotary kiln 10 by the input terminus non-rotating sealing member 22 of inclined feeding pipe 26 and round tube type rotary kiln 10, so, the wall of the tubular furnace charge passage Nei Bei center hot gas path 32 of metal solid waste material before entering round tube type rotary kiln 10 and in round tube type rotary kiln 10 is derived heat and is discharged to the hot gas preheating and drying of center hot gas path 32 external space, material temperature raises, operating efficiency increases, and makes further minimum heat losses.
For the present embodiment, metal solid waste material, as aluminium bits or pop can etc. are transported to stapling machine 60 at first, is cut into fragment or the particle of almost single-size; In order to reject all irony compositions on transfer roller 62, the metal solid waste material of chopping is delivered in weighing-machine 64 and magnetic drum 66, after sucking-off iron content object, by inclined lift transfer roller 68 furnace charge is delivered to have and makes in the minimized hopper 20 of hot gas leakage.
The furnace charge of about 500 DEG C is discharged from the Discharge outlet 28 of round tube type rotary kiln 10, is delivered to vibratory screening apparatus 70 fast, enters smelting furnace 74 through feed chute 72 by lift and conveyer 30; Control of dust petticoat pipe 76 covers on above feed chute 72 to reduce topsoil.
It is after 80s for follow-up manufacture that dissolved aluminum liquid in melting furnace 74 injects aluminium water bag by chute 78.
