To include that feed bin 103, silo support 104, the charging system of insulation feed bin supporting plate 105 are put
In lower hearth 202.
Dry distilling material is inserted above-mentioned charging system.
Closing fire door, the nitrogen of the nitrogen inflation inlet valve 204 and upper furnace body 1 of opening lower furnace body 2 goes out
QI KOU 109 valve, simultaneously closes off nitrogen gas outlet valve 205 and upper furnace body 1 nitrogen of lower hearth 202
Gas inflation inlet 108 valve, replaces the air nitrogen in whole burner hearth, it is possible to for other indifferent gas
Body.
Close lower furnace body 2 nitrogen inflation inlet valve 204 and nitrogen gas outlet 109 valve of upper furnace body 1.
Close heat insulation trapping push-pull valve 111, and open heater switch simultaneously, 102 liters of heat-insulation and heat-preservation burner hearth is set
Temperature program.
After upper furnace body 1 heat-insulation and heat-preservation burner hearth 102 temperature to assigned temperature, open heat insulation trapping plate
Valve 111, starts elevator 207, by feed bin 103, silo support 104 and insulation feed bin torr
The thermal treatment zone of upper furnace body 1 burner hearth sent into by plate 105, starts dry distilling, and heating-up temperature can be 400 DEG C-1600 DEG C.
Dry distilling oil gas is collected from the oil and gas separating system end being connected with dry distilling oil gas vent 110.
After dry distilling terminates, first open nitrogen inflation inlet 204 valve and the nitrogen gas outlet 205 of lower furnace body 2
Valve, it is ensured that lower hearth 202 is nitrogen atmosphere, then starts elevator, feed bin 103, feed bin is propped up
Frame 104 and insulation feed bin supporting plate 105 are transported to lower hearth 202 by upper furnace body 1 burner hearth, close
Heat insulation trapping push-pull valve 111, completely cuts off heat.
After temperature of charge drops to desirable value, open lower furnace body 2 fire door 203, take out material and be analyzed.
It should be noted that each embodiment above by reference to described by accompanying drawing is only in order to illustrate the present invention
And unrestricted the scope of the present invention, it will be understood by those within the art that, without departing from this
The amendment on the premise of bright spirit and scope carried out the present invention or equivalent, all should contain
Within the scope of the present invention.
