Thorax 2 is provided with exhaust outlet at feed end and connects negative pressure equipment, and several pairs of burners 10 are arranged at bottom in the burner hearth 2, often
Burner 10 is mutually staggered in the axial direction of burner hearth 2, the flue gas processing device connects 2 top of burner hearth, the flue gas
Processing unit includes flue gas purification device 3, heat-exchanger rig 4, combustion fan 5；
Preferably, the burner 10 has 8 pairs, six pairs of the setting in the burner hearth 2 of discharge end, in the burner hearth 2 of feed end
Two pairs of setting；
Preferably, the flue gas purification device 3 connects 2 top of burner hearth, flue gas enters heat exchange after passing through flue gas purification device 3
Device 4, the side of the exhanst gas outlet of the heat-exchanger rig 4 are equipped with the combustion fan 5, and the other side is gas line 9, connect institute
State burner 10；
Preferably, described 7 one end of sealed feeder unit is fixed with 6 discharge port of feed screw, 2 activity of the other end and the burner hearth
It is fixed, and the sealed feeder unit 7 has FlexbleJoint.
The present invention in use, material by sealed feeder unit 7 enter boiler tube 1 in be pyrolyzed, burner hearth 2 heating generate
Flue gas after flue gas purification device 3, heat-exchanger rig 4, under the action of combustion fan 5, into the combustion-supporting gas of burner 10
Pipe realizes the recycling of flue gas, and the feed end of boiler tube 1 has nitrogen charging mouth 8, guarantees positive pressure and inert gas in furnace, prevents quick-fried
Fried, burner hearth 2 is arranged exhaust outlet and is adjustable air pressure and temperature in burner hearth 2, whole device good airproof performance, safety coefficient height.
