Description

A kind of continous way wood material carbonization device
One, technical field
The utility model relates to the equipment for pyrolysis charring biological material, especially continous way wood material carbonization device.
Two, background technology
The method of producing gac has two kinds, and one is physical activation method, as taken water vapor as the activation method of activator; One is chemical activation method, as taken phosphoric acid as the activation method of activator.The great advantage that physical activation method produces gac is that production technique is very little on the impact of environment, except producing except a small amount of dust in local, very little on the impact of air and water body environment.Physical activation method produce gac need through raw material charing and activate this two master operations, charing be exactly biomass material or carbon raw material at high temperature carbonization make the process of charcoal.With physical activation method produce gac raw material mainly coal and biomass material as timber, fruit stone shell etc., in the north based on coal, in south based on biomass material.Along with the increasingly stringent that ecological, environmental protective requires, the cutting capacity of timber is restricted, at present China little timber make raw material production gac, replacing is be the more of raw material production gac with wood machining residues or fruit stone shell, as being raw material with wood chip, gac produced by Physical fluidization activation furnace, its quality product is better, with this explained hereafter gac, first wood chip charing will be made sawdust charcoal, then, sawdust charcoal carries out high-temperature activation in fluidized bed furnace.Because the particle of wood chip is thinner, ventilation property is poor, the thermal conductivity of wood chip is less, heat transfer property is poor, moreover be exactly that wood chip produces tar material can be made mutually to be bonded to block in retort process, the self-burning type moving-bed charring furnace being applicable to particle or lumpy material will not be suitable for the charing of wood chip, up till now, good wood chip carbonization device is not also had to be applied to production, now conventional wood chip charing method is lighted wood chip in heaps, then constantly on the wood chip heap of burning, wood chip is added, wood chip is made to be in half state of combustion, the wood chip heap of final water extinguish combustion, like this, reach the object of wood chip charing.This charing method also exists following shortcoming: the carbonization temperature of (1) material is uneven, and the quality of carbonized material is uneven; The state of (2) half burning carbonates controls with the experience of operator completely, as bad in controlled, and may not carbonize completely, also may excessive burning and ashing serious, the yield of charcoal and quality by the sense of responsibility of operative employee and experience influence very large; (3) yield of wood chip charing is lower, and raw material consumption is larger; (4) because wood chip heap is in half state of combustion, produce a large amount of smog, larger impact is produced on surrounding environment; (5) charcoal heap finally needs use water to extinguish and cooling, and the moisture content of the sawdust charcoal obtained is higher, also through drying, both will increase production process, and seeming and comparatively bother, turn increase energy consumption and improve production cost before activating.Therefore, develop advanced and applicable wood chip carbonization device and just seem very necessary.With like these utility classes if application number is the patent of invention of 201110140961.9, dry and charing all adopts external-heat heating, Flow of Goods and Materials mode is helical feed, it is larger that dry and carbonizing tube all can not do, otherwise the bed of material is too thick and can not complete drying and charing, therefore the charing output of this carbonization device is less; Also have application number to be the utility model patent of 201120036641.4, its charring furnace is common external-heat rotating cylinder, and the ulking thickness of material in cylindrical shell is uneven, and the contact area of material and rotating cylinder is very limited, and heat transfer area is less.According to above-mentioned background, the utility model develops and a kind ofly carbonizes the higher sleeve continous way wood material carbonization device of output.
