Abstract

The invention discloses a pecan peel and bamboo shoot skin charcoal and a processing method thereof. The method comprises the following steps: S1, respectively crushing pecan peel, bamboo shoot skin and bamboo to prepare pecan peel particles, bamboo shoot skin particles and bamboo particles; S2, drying the pecan peel particles, bamboo shoot skin particles and bamboo particles until a moisture content reaches 7%-10%; S3, mixing the dried pecan peel particles, bamboo shoot skin particles and bamboo particles evenly, and then molding to prepare firewood rods; and S4, carbonizing the firewood rods by a carbonization furnace. The invention aims to provide the pecan peel and bamboo shoot skin charcoal and the processing method thereof, and has advantages of environment-friendliness, expanded machine-made charcoal material sources, and high yield, high density, high carbon content and high calorific value of the obtained machine-made charcoal.

Description

A kind of pecan Compositions of Bamboo Shoot Shell charcoal and working method thereof

Technical field

The present invention relates to a kind of pecan Compositions of Bamboo Shoot Shell charcoal and working method thereof.

Background technology

Machine-made charcoal, have another name called machine-made carbon, firewood rod, artificial carbon, regenerated carbon, smokeless clean charcoal, excellent carbon feedstock wide material sources, rice husk, Pericarppium arachidis hypogaeae etc. all can be used as raw material production machine-made charcoal, with sawdust, wood shavings, bamboo bits for the best.Machine-made charcoal is widely used in family's heating, broil food, also can be used as industrial raw material, the Viability charcoal of deep processing etc., and because machine-made charcoal density is large, calorific value is high, smokeless, tasteless, pollution-free, is the Green Product of generally acknowledging in the world.

The method preparing machine-made charcoal is for raw material with wood chip (sawdust) etc., drying stove is dried into the suitable standard starting material of humidity, puts into forming machine (rod-made machine), then plastify through High Temperature High Pressure after cooling, make firewood rod (work in-process), eventually pass charring furnace charing.

The object using extrusion formation equipment makes the material forming containing certain moisture, is beneficial to the charing in later stage or is directly used as fuel.Therefore, the water content of raw material and the composition of raw material are the determinatives determining extrusion temperature.The manufacture of machine-made charcoal mainly utilizes the Mierocrystalline cellulose of raw material and the composition of these carbon containings of xylogen to make, from the constituent of raw material, determine its can become desirable machine-made charcoal raw material because have two: Mierocrystalline cellulose takes the quality of knot and the number of content of lignin.The quality that knot taken by Mierocrystalline cellulose directly affects density and the physical strength of moulding stick, and content of lignin then determines the most high carbon content of finished product.The Mierocrystalline cellulose utilized and chemistry of lignin become to belong to the category of carbohydrate, on molecular level containing a lot of hydrophilic radical as formed the glucose of its fundamental unit, containing a lot of hydroxyl, these hydrophilic radicals are affine a lot of water molecules, in extrusion process, if temperature is too low, xylogen can not soften effectively increases viscosity, is unfavorable for high-pressure molding, moisture can not effectively be discharged, the firewood rod squeezed out is bending, or can not be shaping, affects follow-up charing and the yield of fixed carbon; If temperature is too high, xylogen softens too fast, and go out rod speed fast, firewood rod is shaky, moisture rapid evaporation will become water vapour, depart from these hydrophilic radicals, thus make the lines of the explosion of firewood rod or appearance fracture, be unfavorable for the charing in later stage, simultaneously, extrusion temperature is too high, also affects the cost of product, and the conditional request to forming machine.Therefore, extruding plastifies in the process of firewood rod, and the water content of raw material, the temperature of extruding are two parameters crucial in machine-made charcoal making processes.The composition of raw material affects the selection of water content and extrusion temperature.

Semen Caryae Cathayensis is a kind of deciduous tree, belong to Juglandaceae hickory, about there are 20 kinds, China is one of country of origin, as Semen Caryae Cathayensis great industry nation, gathering and in deep-processing process, producing a large amount of pecan Semen Caryae Cathayensis, only have minute quantity at present for peasant household's auxiliary fuel, its main processing mode burns and abandons on the spot.This kind of processing mode, not only to environment, is not suitable with the requirement of Modern Green Economic development.

Summary of the invention

For prior art Problems existing, the object of the invention is to propose a kind of pecan Compositions of Bamboo Shoot Shell charcoal and working method thereof, environmentally friendly, expand the raw material sources of machine-made charcoal, the machine-made charcoal yield of acquisition is high, density is high, carbon content is high, thermal value is high.

For reaching this object, the present invention by the following technical solutions:

Propose a kind of pecan Compositions of Bamboo Shoot Shell charcoal and working method thereof, comprise the steps:

S1, respectively pecan and Compositions of Bamboo Shoot Shell and bamboo wood to be pulverized, make pecan powder, Compositions of Bamboo Shoot Shell powder and bamboo wood powder grain;

S2, dry pecan powder, Compositions of Bamboo Shoot Shell powder and bamboo wood powder grain, until its water ratio is all at 7%-10%;

S3, be mixed even by dried pecan powder, Compositions of Bamboo Shoot Shell powder and bamboo wood powder grain, then forming processes makes firewood rod;

S4, employing charring furnace carbonize firewood rod.

The temperature of described charing process controls between 400 DEG C-900 DEG C.

Also comprise:

Refine the firewood rod after charing process, refining temperature is not less than 900 DEG C.

In S3, in firewood rod, the mass percentage content of pecan powder is 45%-65%; Compositions of Bamboo Shoot Shell powder is 30%-50%; Bamboo wood powder grain is 5%.

Also propose a kind of machine-made charcoal, described machine-made charcoal adopts as any one method in claim 1-4 is made.

Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:

First: the present invention prepares machine-made charcoal with pecan powder, Compositions of Bamboo Shoot Shell powder, bamboo wood powder grain for raw material, solve due to pecan powder, Compositions of Bamboo Shoot Shell powder, bamboo wood powder grain carelessly abandon the environmental pollution caused, expand and manufacture the raw material sources of machine-made charcoal.

Second: machine-made charcoal yield prepared by the inventive method is high, reaches more than 43%, fully and efficiently utilize resource, the machine-made charcoal density of preparation is high, and fixed carbon content is high, reaches more than 68%, thermal value is high, reaches more than 5720kcal/kg, meets national standard.
