Description
Technical field
The present invention relates to agricultural solid residue processing technology fields, and in particular to a kind of promotion feces of livestock and poultry preparation biology
The method of the calorific value of matter charcoal.
Background technique
Livestock and poultry cultivation process generates a large amount of discharged waste, and with the fast development of intensive aquaculture industry, feces of livestock and poultry is given
The very big carrying capacity of environment of local agricultural environment band.Feces of livestock and poultry phosphorus content is high, is rich in a large amount of organic carbon.Carbohydrate
It is the base substance composition of biomass, theoretically biomass can be carbonized.China handles feces of livestock and poultry, especially pig at present
Excrement, there are three types of the modes of mainstream: marsh gas power generation, production biological organic fertilizer and vermiculture processing.But each way has it
Respectively different advantage and disadvantage.
And feces of livestock and poultry can carry out charing process, the waste generated in carbonization process is easy to harmless treatment,
Carbonizing the charcoal obtained can be used as biomass fuel use.But problem is feces of livestock and poultry charcoal after charing process,
Its calorific value about 3000 kilocalories/kilogram or so, used as fuel slightly lower, be unfavorable for marketing.If calorific value energy
Effective promotion is accessed, a kind of beneficial method will be provided to the environmental protection treatment of feces of livestock and poultry.
Therefore, it is badly in need of developing a kind of method for promoting feces of livestock and poultry and preparing the calorific value of biomass carbon.
Summary of the invention
The present invention is directed to above-mentioned defect in the prior art, provides a kind of fever for promoting feces of livestock and poultry and preparing biomass carbon
The method of amount, this method safety and environmental protection can significantly improve the calorific value of feces of livestock and poultry biomass, the animal dung after calorific value promotion
Just charcoal can be used as biomass fuel use, realize the resource utilization of animal faeces wastes.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A method of the calorific value that feces of livestock and poultry prepares biomass carbon is promoted, the difference is that, comprising the following steps:
The feces of livestock and poultry charcoal that charing is completed is pulverized into powder by step 1)；
Step 2 mixes powder obtained by step 1) with certain density acid, mixes it uniformly, sufficiently reacts；
Step 3), step 2 is reacted after mixture be separated by solid-liquid separation, liquid and solid matter after being separated；
Step 3) obtained solid substance is carried out dehydration and drying processing by step 4), finally obtains the feces of livestock and poultry after calorific value is promoted
Charcoal.
In the above-mentioned technical solutions, it in the step 1), is crushed by the modes such as breaing up, grinding, makes powder after crushing
The partial size at end is less than 4 mesh.
In the above-mentioned technical solutions, in the step 2, the concentration of workable acid is 0.5 ~ 5mol/L.
In the above-mentioned technical solutions, in the step 2, acid is at least one of hydrochloric acid, nitric acid or sulfuric acid.
In the above-mentioned technical solutions, in the step 2, powder and acid is made mix and can be used stirring, oscillation etc. a variety of
Mode.
In the above-mentioned technical solutions, it in the step 3), is separated by solid-liquid separation using the modes such as centrifugation or filtering.
In the above-mentioned technical solutions, liquid isolated in the step 3), which may continue as the acid in step 2, makes
With.
In the above-mentioned technical solutions, in the step 4), the modes such as centrifugation, drying, ray can be used and dehydrated
Processing.
Compared with prior art, pass through the feces of livestock and poultry that will carbonize and complete the beneficial effects of the present invention are: the present invention to give birth to
Object powdered carbon is sufficiently mixed with certain density acid react after be separated by solid-liquid separation, the solid matter after separation is dehydrated
Processing, can significantly improve the calorific value of feces of livestock and poultry biomass, and the feces of livestock and poultry charcoal after calorific value is promoted can be used as biology
Matter fuel uses, and realizes the resource utilization of animal faeces wastes, reduces pollution of the feces of livestock and poultry to environment, improve
Ecological environment.
