Abstract

The invention discloses environment-friendly charcoal and a preparing method thereof. The preparing method includes the following steps of 1, raw material treating, wherein agriculture and forestry residual substances are subjected to impurity removing and smashed into grains; 2, fermenting, wherein microbial funguses are added into the raw materials obtained in the step 1 and mixed in proportion, humidity is adjusted, and the mixture is fermented under the aseptic condition; 3, drying and bar preparing and molding, wherein the materials obtained in the step 2 are dried and prepared into bars at the high temperature and the high pressure through a bar preparing machine; 4, carbonizing, wherein the bars obtained in the step 3 are carbonized in a carbonizing furnace, and then are taken out, cooled and packaged to obtain the finished product. According to the environment-friendly charcoal and the preparing method thereof, as the raw materials of the environment-friendly charcoal are fermented through the microbial funguses, the ingredients in the raw-material grains are decomposed, and blasting sparks in the burning process can be effectively prevented.

Description

A kind of environment-friendlycharcoal charcoal and preparation method thereof

Technical field

The invention belongs to fuel processing technique field, be specifically related to a kind of environment-friendlycharcoal charcoal and preparation method thereof.

Background technology

The significant problem that resource plaque is weary, ecological deterioration is world today's facing mankind, finds the great difficult problem faced by renewable sources of energy mankind nowadays just. China is as agricultural production big country, and according to the statistics made by the departments concerned, the residue such as annual agricultural crop straw is 60-70 hundred million tons, but its utilization rate only has 20%, and all the other are as garbage disposal, and branch, sawdust, Caulis et Folium Oryzae, corn stalk etc. also have more than one hundred million ton to be thrown away.

Environment-friendlycharcoal charcoal has two-layer to look like, one be it produce time energy-conserving and environment-protective, two be it use time environmental protection. The raw material sources of environment-friendlycharcoal charcoal are very wide, especially the raw material of the environment-friendlycharcoal charcoal of mechanism very extensive especially: 1, forestry residue: sawdust, wood shavings, bamboo bits, branch, bark, pineal shell, shell etc.; 2, agricultural wastes: rice husk, hemp stalk, corn cob, bean stalk, Sorghum vulgare Pers. stalk, cotton stalk, boll hull, sunflower skin, peanut skin and relatively hard straw kind etc.; 3, industry residue: alditol slag, roasting glue slag, sugarcane bagasse etc.

The exploitation of environment-friendlycharcoal charcoal can make all above waste material become new forms of energy just, save forest (forestry) resource, alleviate Linesless charcoal and supply little sufficient nervous situation, reduce environmental pollution, improve the ecological environment, be conducive to national economy sustainable and healthy development. The product of environment-friendlycharcoal charcoal is mainly used in the civil area such as the industrial circle such as metallurgy, chemical industry and food barbecue, heating, has an advantage in that environmental protection, colorless and odorless during burning, smokeless; Resistance to burning, every 0.5 kilogram of firewood charcoal incendivity 1 hour, and environment-friendlymachine-made machine-made charcoal incendivity per jin 3-4 hour.

Greatly developing the renewable sources of energy, turn waste into wealth, the key subjects that to be State Council propose according to the development trend that society is current, are also the inexorable trends of development in science and technology simultaneously.

Summary of the invention

It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of initial bonding strength is good, just the viscous time is short, and adhesive strength is high, mobility and excellent storage stability, and bond the environment-friendlycharcoal charcoal without premium properties such as warpages, the preparation method that the invention still further relates to this environment-friendlycharcoal charcoal.

The preparation method of a kind of environment-friendlycharcoal charcoal of the present invention, comprises the steps:

1) Feedstock treating: by forest and agricultural biomass remove impurity, be ground into granule;

2) fermentation process: by step 1) obtain addition microbial bacteria in raw material, it is mixed in proportion, adjusts humidity, aseptically ferment;

3) dry, system rod molding: by step 2) drying materials that obtains, made bar at high temperature under high pressure by bar-producing machine;

4) carbonization processes: by step 3) bar that obtains carries out carbonization process in retort, and then take out cooling, pack to obtain finished product.

Step 1 of the present invention) described in forest and agricultural biomass, it is preferable that the lignin material such as sawdust, fruit tree, twig, straw, peanut skin, sorghum stalk, shell, bamboo wood, rice husk, during mixing, for arbitrary proportion; Described pulverizing, it is preferable that granule is less than 3mm.

Step 2) described in microbial bacteria, for yeast, bacillus bifidus, lactic acid bacteria, bacillus cereus, photosynthetic bacteria, actinomycetic one or more, when mixing time, for arbitrary proportion; Step 1) obtain addition microbial bacteria in raw material, it is preferable that mix according to the weight ratio of 1000:1; Step 2) described in adjustment humidity, it is preferable that humidity is 70%, described fermentation, preferably 3 days time.

Step 3) described in drying, it is preferable that control moisture within 12%; Described High Temperature High Pressure, temperature is 150-200 DEG C, and pressure is 60-80MPa; Make bar, it is preferable that make the hollow bar of hexagonal configuration.

Step 4) described in carbonization process with reference to prior art, it is preferable that process 20 hours.

The invention still further relates to the environment-friendlycharcoal charcoal adopting above-mentioned preparation method to obtain.

Compared to existing technology, it is an advantage of the current invention that:

1, the present invention raw material by microbial bacteria fermentation process environment-friendlycharcoal charcoal, has decomposed the composition in feed particles, it is possible to effectively prevent the snuff phenomenon in combustion process.

2, the environment-friendlycharcoal charcoal that the present invention obtains, fixed carbon content, more than 92%, has length burning time, firepower is prosperous, caloric value is big, and ash is low, smokeless, tasteless feature, and existing environment-friendlycharcoal charcoal incendivity 3-4 hour, the environment-friendlycharcoal charcoal that the present invention obtains can be burnt 4.5-6 hour.

3, the environment-friendlycharcoal charcoal that the present invention obtains, every physical and chemical index is superior to common Linesless charcoal, can replace coal, and calorie reaches more than 5000 kilocalories, is suitable for operating mode enterprise burning boiler and uses; Can also be used for heating, in the daily life such as barbecue.
