Abstract
The process of producing biomass briquette includes mixing coal material, biomass adhesive and additive in the weight ratio of 70 to 20 to 10; and forming the mixture. The biomass adhesive is prepared with crop stalk, and through crushing, treating with alkali solution, and adding tar or PAM; and the additive is potassium permanganate and lime. The biomass briquette has the advantages of short dry distillation time, easy separation of volatile component, low burning point, etc.
Description
Technical field
This invention is a kind of production method of biomass coal, belongs to the resource and environment technical field
Background technology
In the non-renewable energy of China, the coal reserves surpass 90%, and at following 50 years, coal will be main energy sources.The coal burning utilization is the diffusing coal of directly burning substantially, a large amount of pollutents such as CO2, SO2 of discharging in atmosphere, and secondary pollution is big.Because the atmospheric pollution that causes of raw coal combustion accounts for 65% of gross contamination thing, severe contamination environment, the raw coal burnout rate is low, causes very big waste.Based on the present situation of topsoil, the cleanburning utilization that solves raw coal has significance.
Biomass coal easily catches fire, efficient burning, low pollute and turn waste into wealth and come into one's own with it.Biomass coal has short, advantage such as volatile matter is easily separated out, burning-point is low, combustionvelocity is fast of destructive distillation time, therefore in combustion processes, biomass coal forms micropore easily, increased contact surface with air, accelerated the diffusion combustion speed on coal grain surface, improve the combustion boundary temperature, thereby reduced the shortcoming of black smoke that incomplete combustion caused and incomplete combustion.On the other hand, biomass coal combines non-renewable coal resources and reproducible Biological resources, has not only reduced the coal pollution problem, and has saved resource, for the possible approach that provides is provided in the mass-producing of biomass energy.
Summary of the invention
The object of the present invention is to provide a kind of production method of biomass coal.
The present invention is achieved in that a kind of production method of biomass coal, it is characterized in that mixing moulding by feed coal, biomass binding agent, additive; The biomass binding agent is meant the agricultural crop straw of using alkaline solution (sodium hydroxide 0.5%～2.0%, calcium oxide 1.0%～4.5%) to handle after three grades of pulverizing, adds tar or PAM again; Additive is potassium permanganate, unslaked lime; Its prescription of biomass coal is: according to mass percent, and feed coal: biomass: additive=70%: 20%: 10%.
Embodiment
1 biomass coal moulding
1.1 material is selected and is handled
1.1.1 coal
Moulding is chosen Chong Shan mining area 1/3 coking coal with feed coal.
1.1.2 biomass
Straw: take near the rural area Gaoqing, seasoning after three grades of pulverizing mix.
1.2 moulding pre-treatment
Feed coal is pulverized, and powder particle diameter is less than 3mm.Biomass after the pulverizing are mixed with alkali, the processing of heating.Alkaline solution is formulated as mass percent sodium hydroxide 0.5%～2.0%, calcium oxide 1.0%～4.5%.According to mass percent, feed coal: biomass: additive (ignition dope, sulphur-fixing agent etc.)=70%: 20%: 10% mixes moulding.In moulding process, add PVA, coal tar, cement etc. respectively and had the material of cementing property.
1.3 moulding
The moulding of biomass coal is to utilize the columnar coal moulding.Moulding product is Φ 20mm * 25mm, and forming pressure is 300～500kg.
1.4 result
Selected straw is after sodium-hydroxide treatment, and the solid, liquid body portion all has cohesiveness, and solid part mainly plays ligation, and liquid portion mainly plays cohesive action, and preceding a kind of effect is stronger.The compound binding agent adhesive capacity that the straw binding agent adds tar or PAM gained is strong, and has water resistance, is a kind of binding agent that practical future is arranged.
China is maximum in the world coal production state and country of consumption at present, and energy structure is still based on fire coal, and the whole nation has 430,000 Industrial Boilers approximately, and 110,000 Industrial Stoves are so the development clean moulded coal becomes an important directions of clean coal technology.And biomass coal easily catches fire, efficient burning, low pollute and turn waste into wealth and come into one's own with it.Facts have proved that development biomass coal technology is to reduce the industry of coal and very one of effective way of civilian pollution.
