Description

A kind of charring furnace device of firing pyrocarbon

Technical field:

What the present invention relates to is a kind of device that the charing raw material is carried out charing.

Background technology:

Make the charing of charing raw material, a lot of equipment are always arranged, primary is to fire charcoal with earth kiln, and then the laminar steel plate charring furnace of useful mongolia yurt type is fired charcoal; The quick low-temperature carbonization stove of also useful square steel plate is fired charcoal; Be to fire charing equipment of charcoal or the like more in addition with square steel plate quick high-temp stove.They all have certain defective and weak point, though at first it is simple in structure for earth kiln, but have poor sealing performance, the charing raw material is inhomogeneous in carbonization process, the incomplete or charing phenomenon too of charing often occurs, make the charing raw material burn till ash easily, in addition, earth kiln is by soil, stone or soil, brick one-tenth, make it without wind and rain, easily cave in, the work-ing life of kiln is short, and earth kiln igniting simultaneously is slow, and the heat radiation of burning back is slow, the smouldering fire postcooling time is long, so the production cycle is long, sintering technology falls behind, and whole sintering procedure carries out with operator's experience entirely, carbonization process is wayward, the output of charcoal and quality are extremely unstable, and the raw material of firing also only is confined to fire not good utilisation farming with firewood forests wood, the waste material of production of forestry, wood chip is fired charcoal, be that earth kiln does not have the tar separation device in addition, environmental pollution is serious in the production; Another kind of square steel plate stove, though it is firm, durable, because this stove is a laminar, it is long to connect the slit, the seal operation amount is big, and very easily cause gas leakage, igniting simultaneously, carbonization time is long, inconvenient operation, fire still and carry out by rule of thumb, become the difficult quality guarantee of charcoal, also do not remove tar equipment, still have the pollution problem of sintering procedure environment; Also having a kind of is square steel plate quick high-temp charring furnace, it is a kind of iron-clad structure of integral body, seal degree is better, transportation is installed also convenient, certain combustion-assistant ignition device is also arranged, it is also fast and reliable to ignite, temperature demonstration and cooling provision and tar separation facility are also arranged, but can not reclaim tar, smoke evacuation still can not be up to standard, it is low to close fiery temperature, generally have only≤500 ℃,, do not possess the condition of firing pyrocarbon so can only fire the low temperature charcoal, it also exists the body of heater volume little in addition, fire yield poorly etc. not enough.

Summary of the invention:

The objective of the invention is to provide a kind of improved device that makes the charing raw material carry out better charing, this device can make furnace body temperature reach degree more than 1000 ℃, make it to burn high-quality pyrocarbon, this equipment can make tar separation reclaim effectively simultaneously, purify the flue dust that produces in the sintering procedure, it is up to standard to make it emission gases, does not produce pollution in the whole process.
