Abstract

The invention discloses a method for producing charcoal by Ricinus communis L. straws, and belongs to the technical field of biomass energy development. The method comprises the following steps: selecting a Ricinus communis L. stalk of which the main stem diameter is greater than 5cm, cutting out a Ricinus communis L. stem section of which the length of the main stem part is 60-80cm, and exposing the cut Ricinus communis L. stem section under sun until the moisture content of the Ricinus communis L. stem section is about 50%; sending into a carbonization furnace, keeping temperature in the furnace at 300-320DEG C, continuing to burn for 4-5 days, isolating air, and utilizing waste heat to continue to heat and carry out dry distillation for 4-5 days to obtain Ricinus communis L. charcoal. When the method is used for producing the charcoal, the method fully utilizes Ricinus communis L. straw resources, makes waste profitable, has a simple charcoal manufacture working procedure, and is an environmentally-friendly good method which can save time and labor and save cost. The Ricinus communis L. stalk of which the main stem diameter is greater than 5cm is selected as charcoal materials, and the Ricinus communis L. stalk has high lignification degree, low combustion ash content and high charcoal yield.

Description

A kind of method producing Linesless charcoal with Semen Ricini straw
Technical field
The present invention relates to Technologies of Biomass Energy Exploitation field, particularly relate to Semen Ricini straw and prepare Linesless charcoal Method.
Background technology
Semen Ricini (Ricinus communis) is dicotyledonous annual or perennial tall and big wooden draft, cane Sturdy, in have joint in vain.Originate in Africa, the most incoming Asia, America, Europe, well developed root system, growth Strong adaptability, Salt And Alkali Tolerance, extensive growth is in the torrid zone, subtropical zone and temperate countries.As the big oil plant in the world ten One of crop, castor bean oil content is up to 46% 56%, and Oleum Ricini has that low temperature does not solidifies, high temperature does not burns Unique chemical characteristic, the product with Oleum Ricini as raw material is up to kind more than 3000, is referred to as " reproducible Green (pollution free) petro ", it is widely used in the fields such as the energy, chemical industry, medicine, light industry.Except this, current Semen Ricini The research of comprehensive utilization also includes: cake is cooked feedstuff, blade sericulture, cane papermaking and wood-based plate processed.Domestic To the demand of castor bean, supply falls short of demand always, and currently plants that the Semen Ricini output value is relatively low have impact on the positive of peasant Property, therefore comprehensive utilization Semen Ricini is the key of development Semen Ricini industry.Semen Ricini bar is fired the technology of Linesless charcoal and is not had so far Have been reported that.
Linesless charcoal is timber or wood material through imperfect combustion or isolation air thermal dissociation, generation loose many Hole fuel, Linesless charcoal is used as fuel value height, smoke-free and tasteless.Need to cut down in a large number tree using timber as raw material Wood, runs in the opposite direction with protection of natural resources and environment, and with straw for raw material production charcoal, makes full use of money Source, turns waste into wealth, and avoids straw simultaneously and stacks or Air-pollution From Combustion environment.Charcoal production stage bag Include: raw material screening, raw material pulverizing, dry, rod processed and carbonization, labor cost height becomes charcoal valency The main cause that lattice are higher.
The present invention prepares Linesless charcoal with Semen Ricini straw for raw material, and advantage includes: one, and Semen Ricini growth cycle is short, Cane is sturdy, and Biomass is big；Its two, straw fires Linesless charcoal, turns waste into wealth, and makes full use of resource, simultaneously Avoid stacking the environmental pollution that crop straw burning causes；Its three, charcoal processing operation is simple, it is not necessary to pulverizes and makes Rod, it is only necessary to dry and carbonization is time saving and energy saving；Its four, in terms of economic benefit, increase the Semen Ricini output value, band Dynamic cultivating castor-oil plant, promotes that Semen Ricini industry develops in a healthy way.
Summary of the invention
It is an object of the invention to make full use of Semen Ricini biomass resource, fire Semen Ricini stalk wood by simple operation Charcoal.The Semen Ricini stalk charcoal burning value that the method is fired is close with charcoal.
The above-mentioned purpose of the present invention is achieved by techniques below scheme:
(1) material prepares: choose the Main stem diameter castor anesthesia stem more than 5cm, intercepts stem partial-length and is The Semen Ricini stem section of 60cm～80cm；
(2) be dried: the Semen Ricini stem section cut be placed under sunlight be exposed to the sun to Semen Ricini stem section moisture be 45%～ 55%；
(3) carbonization: Semen Ricini stem section step (2) being dried is sent in charring kiln, and kiln in-furnace temperature exists 300 DEG C 320 DEG C, persistently burning completely cuts off air after 4-5 days, utilizes waste heat to continue heating dry distilling and 4-5 days is Obtain Semen Ricini stalk Linesless charcoal.
Compared with prior art, the invention has the beneficial effects as follows:
Compare with rice husk, Pericarppium arachidis hypogaeae, boll hull, corn cob, corn stalk, sorghum stalk, bean stalk, sawdust, wood Bits, wood shavings, pine grain shell, Exocarpium cocois (Cocos nucifera L) etc. make raw material production charcoal, hard with Semen Ricini bar xylem, stem Stalk sturdy (give birth to then stem stalk up to more than 5cm, Second Year is up to more than 10cm), Biomass is big, produces Technique is simple, it is not necessary to pulverize and rod processed, it is only necessary to being dried and carbonization i.e. can be used for firing Linesless charcoal, save time province Power, production cost is low, high financial profit.Compare and be processed into Linesless charcoal with timber, timber charcoal time-consuming half Individual month, and Semen Ricini straw charcoal is fired and is only needed about 9 days.
It is charcoal material that the present invention chooses the Main stem diameter castor anesthesia stem more than 5cm, and its degree of lignification is high, Combust is less, and char yield is higher.
Detailed description of the invention
Embodiment 1
Choose 2 years after seed of the gathering high bar Semen Ricini of life, the Main stem diameter castor anesthesia stem more than 5cm, cuts down After stem is cut into the Semen Ricini stem section of 70cm length, 3 days Semen Ricini stem section moistures of being exposed to the sun under sunlight reach 50%, The Semen Ricini stem section that about 5 tons are exposed to the sun is sent in charring kiln, is simultaneously introduced branch and does not reach Semen Ricini stem segment standard Stem section be used as fuel (garbage can be made full use of), the 300 DEG C of carbonizations of kiln in-furnace temperature process, persistently burn 5 Completely cut off air after it, utilize waste heat to continue heating dry distilling 4 days, within i.e. 9 days, be prepared into Semen Ricini stalk Linesless charcoal.
Contrast mechanism's Linesless charcoal and common Linesless charcoal, the indices of detection Semen Ricini stalk Linesless charcoal, it is shown in Table 1.
Table 1 contrast mechanism's Linesless charcoal and Semen Ricini stalk Linesless charcoal Testing index
Contrast mechanism's Linesless charcoal, common Linesless charcoal and the strengths and weaknesses of Semen Ricini stalk Linesless charcoal, be shown in Table 2.
Table 2 charcoal, common Linesless charcoal and the pluses and minuses of Semen Ricini stalk Linesless charcoal
