Abstract
The process of producing shaped charcoal with solid tobacco waste includes the following steps: pre-treatment of the material, continuous charring, shaping and drying. The present invention changes waste into useful material, and has the advantages of environment friendship, low production cost, low power consumption, etc. The produced shaped charcoal has wide use.
Description
Technical field
The present invention relates to a kind of is the method for feedstock production forming charcoal with the solid tobacco waste.
Background technology
At present, charcoal all is to fire with fire wood to form, and has another name called hard charcoal, steel charcoal.Be that a kind of outward appearance of being made by contenting carbon material is black, the internal voids structure is many, fuel value is high carbon material.Act as a fuel, it is easy to use, smokeless, nontoxic, pollution-free, thermal value is high.As functional carbon material, it has certain adsorptive power, has anticorrosion, moistureproof, deodorization, anti-electromagnetic radiation, effect such as eliminate the unusual smell.
Charcoal is widely used in scientific research and sector of the national economy and the daily life, various places businessman development and use charcoal is made multiple daily necessitiess such as charcoal shoe-pad, charcoal cushion, charcoal bolster, also make various washing composition and makeup with charcoal, make various barbecues, warming, baking agricultural-food with its heating, make high-grade well-known tea and industrial fuel, in energy-intensive today, its demand has the trend of steady-state growth.
Yet how therefore raw material timber, the wood chip growing tension of preparation charcoal, enlarge the raw material sources of producing charcoal, reduce raw materials cost, have become the urgent problem that the charcoal industry faces.
In addition, existing charcoal preparation technology generally adopts carbonization of wood principle, produces high-temperature gas by timber self or other fuel, and raw material is finished charing under high temperature anoxybiotic condition, and the mode of production is batch production, and production efficiency is lower.
Summary of the invention
The object of the present invention is to provide a kind of raw material sources wider, production efficiency is higher, the method for utilizing preparing formed charcoal from tobacco solid castoff that production cost is lower.
The objective of the invention is to be achieved through the following technical solutions.
With the solid tobacco waste is raw material, by steps such as pulverizing, continuously carbonizing, moulding, and the forming charcoal of preparation different shape.Below each step is specified.
(1) raw materials pretreatment: raw material is a solid tobacco waste, comprise the discarded stalk material, dust, the broken end of tobacco leaf that produce in the tobacco leaf course of processing, go mouldy, inferior tobacco, the solid waste behind eggplant Buddhist nun alcohol, nicotine, medicinal extract, the absolute oil is extracted in the comprehensive utilization of tobacco and tobacco waste; Solid waste for extract eggplant Buddhist nun alcohol, nicotine, medicinal extract, absolute oil without comprehensive utilization was soaked in water earlier 12-24 hour, solid-liquid separation dehydration again; With handled without the comprehensive utilization solid tobacco waste or/and the solid tobacco waste that produces in the comprehensive utilization process dry or dry to water content 10-20%, fragmentation;
(2) continuously carbonizing: continuously pretreated raw material is sent into the coking chamber charging opening with 60-120 centimetre/hour speed, raw material is travelled forward with 0.5-3 rev/min speed of rotation, pass through coking chamber; Add crop stalk in the combustion chamber that is positioned at below the coking chamber, grate is equipped with on the top, and it is ignited, when raw material travels forward by coking chamber with rotation mode, burn with the crop stalk that adds in grate falls into the combustion chamber in the broken end of part, the high-temperature gas that produces is by the solid tobacco waste in the motion, make it under 200-380 ℃ of temperature,, finish continuously carbonizing through 4-8 hour; Carbide is discharged continuously from the coking chamber discharge port that is in coking chamber opening for feed opposite;
(3) moulding: in carbide, add and be equivalent to its weight 0.5-1 water doubly, stir; The carbide that will add then behind the water is sent into the mould extrusion forming, makes the moisture forming charcoal of desired shape and size;
(4) drying: moisture forming charcoal is delivered to kiln, 100 ℃～110 ℃ dry 1.5-3.5 hour, be cooled to room temperature, promptly get the forming charcoal product.
The present invention is the feedstock production forming charcoal with the solid tobacco waste, changes the useless useful thing that is, reduces land seizure, reduces the generation of secondary pollution, and environmental benefit is obvious; Do not consume timber, have good ecological benefits; Reduced the forming charcoal preparation cost; Manufacture safety, the technology advantages of simple, energy consumption is low; The forming charcoal product of making, easy to use, of many uses; Good stability, storage and convenient transport, safety.
