Abstract
The invention relates to technology for producing biochar by processing and converting waste fungus dregs, in particular to the biochar and a production method thereof. The biochar of the invention comprises 50 to 75 weight percent of waste fungus dreg, 10 to 40 weight percent of coal gangue and 10 to 15 weight percent of water. The biochar and the production method thereof make wastes profitable, save energy, reduce land resources occupied by the wastes, ensure low processing cost and have remarkable economic and social benefits.
Description
Technical field
The present invention relates to utilize the technology of useless bacterium slag processing inverting biological charcoal, particularly a kind of charcoal and production method thereof.
Technical background
China is world Edible Fungi big country, produce edible mushrooms and will produce a large amount of useless bacterium slags, the whole nation produces 5,000 ten thousand tons of useless bacterium slags every year approximately, has only 5.5% fertilizer and 2% that is used for farm crop to be used to do fuel and uses, the most of abandonment handled, and causes certain influence to environment.The starting material overwhelming majority of producing edible mushrooms is the waste after crops leftovers and the Forest products processing, and the useless bacterium slag behind the production edible mushrooms is suitable for the raw material of processing biological energy product based on organic content very much.
Coal gangue is the barren rock of coal association, accounts for the 10-25% of colliery coal mining amount.More than 40 hundred million tons of national annual generations, and still increasing year by year, so that waste a large amount of land resourcess, cause to environment to have a strong impact on.
Summary of the invention
It is the charcoal that raw material is produced to produce the useless bacterium slag that edible mushrooms was produced and to abandon coal gangue that the object of the invention provides a kind of, with and production method.
Technical solution of the present invention: a kind of charcoal, comprise useless bacterium slag, coal gangue, water, wherein useless bacterium slag accounts for weight ratio 50-75%, and coal gangue accounts for weight ratio 10-40%, and water accounts for weight ratio 10-15%.
A kind of charcoal production method may further comprise the steps:
A pulverizes, and colliery powder is broken into powdery, water content is accounted for the useless bacterium slag of weight ratio 35-50% be broken into particulate state;
The B raw material is mixed, and will account for the moisture useless bacterium solid impurity particle of weight ratio 60-90%, and weight ratio 10-40% colliery powder stirs;
The C sterilizing, drying with moisture useless bacterium solid impurity particle and the heating of colliery powder compound, make mycelium death in the compound, and the water content of compound is reduced to 10-15%;
The D moulding is sent the compound of sterilizing, drying into the high-pressure forming machine compressed moulding.
The colliery powder size is the 50-150 order.
Moisture useless bacterium solid impurity particle and colliery powder compound churning time are 15-30 minute.
Moisture useless bacterium solid impurity particle and colliery powder compound Heating temperature are 120-130 ℃, and keep 20-30 minute.
The colliery powder size is the 50-150 order.
Moisture useless bacterium solid impurity particle and colliery powder compound churning time are 15-30 minute.
Moisture useless bacterium solid impurity particle and colliery powder compound Heating temperature are 120-130 ℃, and keep 20-30 minute.
The present invention makes former abandonment and causes the useless bacterium slag of environmental pollution, coal gangue processing to change into biological quality energy product " charcoal ", make thermal value be lower than the useless bacterium slag of 1800 kilocalorie/kilograms and one, the two class coal gangues that thermal value is lower than 800 kilocalorie/kilograms, change into the biomass energy product innovation " charcoal " of thermal value by processing up to 8000 kilocalorie/kilograms, turn waste into wealth, not only save energy has also reduced waste land occupation resource; Charcoal is the thermal value height not only, and can reduce by 70% above greenhouse gases CO than fire coal
2With 85% above SO
2Deng noxious gas emission, the protection environment there is significant effect; This charcoal low processing cost, produce market is wide, and remarkable economic efficiency and social benefit are arranged.
