Description of the drawings
Fig. 1 is the structural representation of the utility model pre-oxidation furnace.
Specific embodiment
It is understandable to enable above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings to this
The specific embodiment of utility model is described in detail, and incites somebody to action above and other purpose of the present utility model, feature and advantage
Become apparent from.Identical reference indicates identical part in whole accompanying drawings.Not deliberately accompanying drawing drawn to scale, emphasis
It is that purport of the present utility model is shown.
As shown in figure 1, a kind of pre-oxidation furnace, including body of heater 7, the left side of the body of heater 7 is provided with blast chamber 14, and right side sets
New air compartment 4 is equipped with, the top of the body of heater 7 is provided with the first air channel 3, and bottom is provided with the second air channel 11, the blast chamber 14
Communicated with the new air compartment 4 by the air channel 11 of first air channel 3 and second, between the air channel 11 of first air channel 3 and second
To pre-oxidize area, Multi-layer warming plate 10 is provided with the pre-oxidation area, wire passage is formed between the heating plate 10, it is former
Silk 4 is passed through from the wire passage, and in the pre-oxidation area, the side adjacent with the blast chamber 14 is provided with downward-sloping
Chin spoiler 2 and acclivitous baffle upper plate 12, the chin spoiler 2 and baffle upper plate 12 are in the blast chamber 14
Portion forms opening, and in the pre-oxidation area, the side adjacent with the new air compartment 8 opens up and multiple through holes, in first air channel
The first valve 5 is provided with 3, the second valve 9, the valve 9 of first valve 5 and second are provided with second air channel 11
It is connected with incinerator by pipeline.Be provided with the blast chamber 14 first air blast 1 relative with the first air channel 3 and with
The second relative air blast 13 of second air channel 11, the new air compartment 8 is connected with new blower fan 6.
During this is new, the precursor in stove is heated by heating plate 10, the first air blast 1 and the second air blast 13 lead to
The first air channel 3 and the second air channel 11 are crossed to the air blast of new air compartment 8, while new blower fan 6 also injects fresh air, gas into new air compartment 8
Stream enters pre-oxidation area by through hole, and afterwards in the presence of chin spoiler 2 and baffle upper plate 12, airflow circulating returns blast chamber 14
It is interior, thus complete a circulation, chin spoiler 2 and baffle upper plate 12 can prevent the first air blast 1 and the second air blast 13
The air-flow that air-flow flows out with pre-oxidation area is interfered, and opening the first valve 5 and the second valve 9 can cause part thermal current to enter
Enter incinerator, incinerator is just capable of achieving hot air circulation and uses to being vented after its catalytic decomposition, so, from containing that pre-oxidation is protected out
There is the hot-air of decomposition and product, a part of to be vented Jing after incinerator catalytic decomposition, another part is recycled in stove；Together
When, supplement a part of fresh air through new blower fan 6.A discharge part, a circulation part, supplements a part, can avoid a large amount of
Heat energy is discharged gas and takes away, and repeatedly circulation can be avoided again and catabolite is enriched with, and fiber is polluted, and so circulates profit
With energy consumption is greatly reduced, while being provided with multilayer wire passage, the process of a plurality of precursor can be once completed, be substantially increased
Processing speed.
