Detailed description of the invention
This equipment is designed fully according to the form described in summary of the invention in its detailed description of the invention.
To be described further at this.Seeing figures.1.and.2, " metal solid waste material heat treatment apparatus " is main
Being made up of the cylinder type rotary kiln 10 forming sealed furnace firing chamber, the rotary shaft of rotary kiln is solid from the metal in left side
Body waste material input process material outfan to the right is in tilted layout, and the two ends of cylinder type rotary kiln 10 connect
Input non-rotating sealing member 22 and outfan non-rotating sealing member 24, with cylinder type rotary kiln 10
Coaxial center hot gas path 32 extends to outfan non-rotating sealing member 24 front end from hot gas inlet 14
Space, firing chamber, i.e. stretch to the upper space of the discharge end outlet 28 of cylinder type rotary kiln 10, from
And form the tubular furnace charge passage being made up of cylinder type rotary kiln 10 outer wall and center hot gas path 32.
Metal solid waste material enters cylinder type revolution from feed hopper 20 through open-ended inclined feeding pipe 26
In tubular furnace charge passage in kiln 10, and by this furnace charge passage, after the steam inversely passed through heating from
Discharge end outlet 28 is discharged, and falls into afterwards on lift and conveyer 30.
For preheating and controlling the heating steam of temperature after input non-rotating sealing member 22 is adjacent
The lower end of burner 37 is derived by hot-blast conduit 36 and is fed to center hot gas path through hot gas inlet 14
In 32.
In order to prevent numerous sealing position leakage pollution gas, flowing gas in cylinder type rotary kiln 10
Stress control be negative pressure.
In cylinder type rotary kiln 10, the negative pressure of flowing gas is by being positioned at input non-rotating sealing member
The centrifugal blower 38 draft effect of 22 top exhanst gas outlets, non-rotating close being attached thereto logical input
Negative pressure is formed at the top of envelope component 22, and the air outlet of centrifugal blower 38 is connected with smokejack 40 by pipeline
Logical, smokejack 40 upper end with afterburner 37 again connects.
Enter into the circulation steam in cylinder type rotary kiln 10 initially directly not connect with metal solid waste material
Touch, in being introduced into center hot gas path 32, transfer out heat；Then, from the non-rotating airtight structure of outfan
Part 24 space returns to the space of input non-rotating sealing member 22, with the gold in cylinder type rotary kiln 10
Sailing against the current in the direction belonging to the solid waste direction of motion contrary, directly heats metal solid waste material；Finally,
The draft utilizing centrifugal blower 38 is drained into the upper end of afterburner 37 through smokejack 40.
Afterburner 37 can use gas with various fuel and different types of burner.Afterburner 37
After-burner 42 design temperature necessarily be greater than the temperature in cylinder type rotary kiln 10, to reach to make heating give up
Material floating coating composition and other pollutant component in after-burner 42 at a temperature of carry out chemical reaction and obtain
The purpose processed with removal to pyrolysis.The burning gases discharged bottom after-burner 42, through cylinder type
The upper end of afterburner 37 is returned to by centrifugal blower 38 and smokejack 40, wherein after rotary kiln 10
A part can be recycled, major part is through the steam heat exchange that is connected with the upper end of afterburner 37
After cooler 47 cooling heat transferring, then deliver to warp after pollution control device 50 processes through lateral 46
Secondary smokejack 52 is discharged.
Metal solid waste material is non-rotating close by the input of inclined feeding pipe 26 and cylinder type rotary kiln 10
Envelope component 22 advances to the main region of cylinder type rotary kiln 10, and so, metal solid waste material is entering
Tubular furnace charge passage Nei Bei center steam before cylinder type rotary kiln 10 and in cylinder type rotary kiln 10
The wall of passage 32 is derived heat and is discharged to the steam preheating and drying of center hot gas path 32 external space, material temperature
Raising, working performance increases, and makes further minimum heat losses.
For the present embodiment, metal solid waste material, initially it is transported to cutting machine such as aluminum bits or pop can etc.
60, it is cut into fragment or the particle of almost single-size；In order to reject all irony compositions on conveyer 62,
The metal solid waste material of chopping is delivered in weighing-machine 64 and magnetic drum 66, after sucking-off iron content object,
It is delivered to furnace charge by inclined lift conveyer 68 to have in the feed hopper 20 making hot gas leakage minimize.
The furnace charge of about 500 DEG C is discharged, by lift and conveyer from the Discharge outlet 28 of cylinder type rotary kiln 10
30 are quickly delivered to vibrosieve 70, enter fusing stove 74 through feed chute 72；Dust petticoat pipe 76 covers on
To reduce atmospheric pollution above feed chute 72.
It is after 80s for follow-up manufacture that dissolving aluminum liquid in melting furnace 74 injects aluminum water bag by chute 78.
