Abstract

The process of making high temperature charcoal includes the steps of: treating biomass material, charring the biomass material,, crushing charcoal, forming in a forming machine, stoving formed charcoal rod, and packing high temperature charcoal product. The present invention needs additional heat source for baking high temperature charcoal, has wood tar added into crushed charcoal, can produce high temperature charcoal with agricultural and forestry wastes and make best utilization of resource, and is environment friendly.

Description

The method for cooking of pyrocarbon

Technical field

The present invention relates to a kind of method for cooking of pyrocarbon.

Background technology

Usually artificially synthesized charcoal is that various biomass materials such as crop, tangerine stalk, branches and leaves, wood chip, rice husk and waste are reasonably being cooperated after pulverize, high temperature is squeezed into bar-shaped fuel, through charing equipment bar-shaped fuel charring is formed machine-made carbon again, the method of charing after the just common first moulding that claims, its technical process is: biomass material → biomass material curing → one-tenth section bar → charing → forming charcoal; But it is rationally to cooperate various types of biomass materials such as crop tangerine stalk, branches and leaves, wood chip, rice husk and waste first charing to become powdered carbon under certain condition that a kind of method is also arranged, again with a kind of non-metallic minerals with combustion-supporting, expanded, cohesive action through calcining, boiling, behind the charcoal compound agent and powdered carbon thorough mixing that electrolysis, filtration are made, the machine-made carbon of making by shaper, the charcoal of this synthetic, higher and even, the anti-burning of calorific value, the method for Here it is so-called first charing aftershaping.These two kinds of charcoal processing methods all have certain weak point in making processes, the former has strict requirement at water content and the fineness to biomass material in the treating processes of biomass material, simultaneously, (when being moulding) is also higher to the requirement of temperature in the biomass material solidification process; And the latter will add in the powdered carbon moulding process combustion-supporting, expanded, binding agent (charcoal compound agent), in the process of producing the charcoal compound agent, also seem very complicated, it must just can make this compound agent through calcining, boiling, electrolysis, filtration by nonmetallic mineral, not only production technique seems comparatively complicated, has increased the production cost that becomes charcoal simultaneously again; More outstanding is that these two kinds of method charcoal processings are bigger to topsoil.

Summary of the invention

The objective of the invention is to provide a kind of novel method of firing pyrocarbon, this method can well be utilized biomass material very easily in sintering procedure, can make full use of the agroforestry production waste, waste, these wastes are carried out ecological, environmental protective to be handled, in becoming the charcoal process, need not add the charcoal compound agent of special production simultaneously, do not need in the moulding process to heat in addition, length to raw material, fineness requirement is not tight, and in the whole process of charcoal processing, can not produce any pollutent to external world, simplify simultaneously the technology that becomes charcoal again, produced the finished product charcoal that meets the pyrocarbon standard.

Technical scheme

The object of the present invention is achieved like this: we adopt when design implementation: handle biomass material, biomass material and carry out charing become pyrocarbon, pulverize charcoal material, the carbon rod after shaper moulding, moulding handled after the charing dry processing, finished product pyrocarbon, check, packing in stoving oven in charring furnace; Less demanding to moisture content when handling biomass material, between 10-60%, the length of biomass material, fineness do not have specific requirement yet, as long as generally can put in the charring furnace to the moisture requirement of biomass material for we; Biomass material charing in charring furnace is that we fire one of key of pyrocarbon, at first our charring furnace of transformation has the blast inlet that can regulate air output, this charring furnace has flue dust tar to handle retrieving arrangement besides, we can show according to the situation of temperature in the stove in the carbonization process, adjusting by the ventilation opening switch size, can make the interior temperature of stove reach 700-1000 ℃, simultaneously can control carbonization time according to the temperature in the stove,, keep carbonization time and be controlled at more than 700 ℃ as temperature: 10-12 hour; Charcoal material after the charing will pulverize, and will add the water of 40-45%, the starch of 2.5-3.5% and the water tar of 4-8% when pulverizing in the powdered carbon, and starch, wood tar oil all add in the entry and together add in the charcoal material, and the powdered carbon fineness requirement after pulverizing reaches the 100-250 order; Charcoal material after the pulverizing carries out the moulding of charcoal in shaper, requiring forming pressure is 10-14kg/cm ², become the specification of charcoal to produce according to customer requirement; Carbon rod after the moulding enters the stoving oven oven dry again, oven dry will be dried by the fire under 70 °-80 ℃ temperature 29-31 hour; Stoving oven is equipped with flue dust wood tar oil recycling and processing device simultaneously; Finished product charcoal after the oven dry will carry out strict check, requires the finished product flawless, does not have broken angle, that the charcoal face is straight is smooth, carbonaceous is harder, ash≤4%, fugitive constituent≤10%, proportion 〉=1 gram/m ³, carbon content 〉=80%, and up to 90%, thermal value 〉=7500 kilocalories is packed after the check.General every case is equipped with 10-15kg, and the carton of packing into behind the ppc inner bag of packing into earlier encapsulates then.

Positively effect

The present invention can utilize biomass materials such as agriculture and forestry organic waste material well; it is carried out ecological, environmental protective handles; can reclaim wood tar oil and utilize in becoming charcoal makes the charcoal processing process no longer produce pollution; ecological resources have been protected; curb environmental pollution, realized regeneration, the purpose of cyclic production to natural resources.This method processing ease, charcoal processing cost are low, and ecological, society, economic benefit are obvious.

Embodiment

The biomass material of water content at 10-60%, put into charring furnace and carry out charing and handle, after stove Nei Wenduda was 300 ℃, the big I of the blast inlet by regulating charring furnace made that temperature arrives more than 700 ℃ in the stove; Temperature in the stove was kept carbonization time 10-12 hour in the time of 700 ℃, went out charcoal then, the water of 40-45% will be added in the charcoal material, the wood tar oil 4-8% that the starch of 2.5-3.5% and charring furnace, stoving oven reclaim, the powdered carbon after pulverizing keep forming pressure at 10-14kg/cm in shaper ²And make carbon rod by the specification of customer requirement, then carbon rod in stoving oven, keep temperature 70-80 ℃ down oven dry after 29-31 hour carbon rod go out stoving oven, test, flawless, do not have broken angle, that the surface is straight, the slick qualified pyrocarbon of carbon rod is packed is promptly good.
