Example Embodiment
[0032] Example 1
[0033] 700℃ high-temperature bituminous coal particles are fed into the main body of the screw conveyor from the material inlet, the screw shaft is controlled by the motor and the screw blades are driven, and the coal particles are conveyed and discharged from the outlet; under 700℃ temperature conditions, coal particles may be thermally desorbed Volatile matter, the generated pyrolysis gas and tar enter the solid insulation sealing device through the screw shaft interface, and the pyrolysis gas and tar are taken out by the washing of sand, and part of the heat is brought out, reducing the temperature; cooling by circulating air Reduce the temperature of the screw shaft; through the cooling effect of circulating water, further reduce the temperature of the screw conveyor shell.
Example Embodiment
[0034] Example 2
[0035] The high-temperature lignite particles at 750°C are fed into the main body of the screw conveyor from the material inlet. The motor controls the screw shaft and drives the spiral blades to transport the coal particles out of the outlet; at 750°C, the coal particles thermally desorb volatiles, resulting in gas and The tar enters the solid insulation sealing device through the screw shaft interface, and the pyrolysis gas and tar are taken out by the scouring of the coal ash, and some heat is taken out; the temperature of the screw shaft is reduced by the cooling of the circulating gas; The cooling effect further reduces the temperature of the screw conveyor shell.
