Sealed between cylinder by packing seal, prevent outside air from entering combustion chamber.Refractory insulating layer is fixed by fixture
Inside burning chamber shell, reach the purpose that heat-insulation and heat-preservation reduces heat loss.
Burner along swinging destructive distillation furnace tube tangential direction be installed on swinging destructive distillation furnace tube and chamber cavity it
Between, burner nozzle is sure not directly to be directed at swinging destructive distillation furnace tube, and otherwise thermal-flame can cause swinging destructive distillation furnace tube
Deformation.
Deflector is staggeredly welded in inside burning chamber shell, deflector one end and combustion chamber side plate weld, the other end and combustion
Burn room side plate and leave a fixed gap, the high-temperature flue gas after burning is under the guide functions of deflector, and S-type route is around row of baffles
Enter, add residence time of the high-temperature flue gas in combustion chamber, greatly improve the thermal efficiency.High-temperature flue gas is around swinging gas retort
After cylinder one week, discharged through exhanst gas outlet, subsequently into air heat exchanger, meanwhile, cool ambient air enters through inlet of cold air
Air heat exchanger, after cold air fully exchanges heat with high-temperature flue gas in air heat exchanger, cold air becomes hot-air, and by hot empty
Gas outlet discharge, then enter burner through burner hot-air inlets, provide oxygen for combustion for burner；After oil shale retorting
Fuel of the caused flammable fixed gas as swinging gas retort, burner, high temperature air are entered by burner fuel gas inlet
Certain component mixing after-combustion is pressed with flammable fixed gas, thermal source is provided for swinging gas retort.In heat exchanger after heat exchange cools
Flue gas, then by heat exchanger exhanst gas outlet through enter downstream fume gas processing system, be discharged into air after purification.
Baffler is welded in inside burning chamber shell, it is therefore an objective to prevents high-temperature flue gas from thus locating directly to arrange through exhanst gas outlet
Go out, cause high-temperature flue gas short-circuit.
Beneficial effect：Caused flammable fixed gas is the fuel of gas retort itself after the present invention utilizes oil shale retorting, is led to
The hot-air crossed after unique deflector and heat exchange designs as oxygen needed for burner, and increase high-temperature flue gas is in combustion chamber
Residence time, heat exchanger effectiveness is greatly improved, effectively reduce the energy consumption of system, simple in construction, energy-conserving and environment-protective.
