Description

A kind of preparation method of biomass solid formed fuel
Technical field
The present invention relates to the fuel fabrication technical field, especially a kind of preparation method of biomass solid formed fuel.
Background technology
Biomass material is the fuel of coal, natural gas and oil, and according to experts' analysis, biomass may become the important component part of the Sustainable development energy.China is the abundant country of a biomass resource, but does not obtain comparatively reasonable use as yet, and in today of energy worsening shortages, it is necessary rationally to utilize the biomass data to exist.In addition, domestic papermaking constantly develops, but the environmental problem that causes thus is also outstanding day by day, and it mainly shows as the generation of a large amount of waste sludge from paper mill mud.Paper mill sludge is that waste water and contains the wood fibre of suitable composition through the end product of precipitation process in the paper-making process in the waste sludge from paper mill, and the short fiber of plant material also contains the flammable composition of great number of organic matters.
The biomass material of China is discarded serious at present, also causes the ample resources waste when influencing environment; And the treatment process of waste sludge from paper mill mud mainly still adopts direct landfill method and burning method, and the consequence that this method is brought is to take a large amount of soils, and and the environment around the landfill yard is caused secondary pollution.This just becomes the bottleneck of restriction socio-economic development.Burning disposal needs to drop into a large amount of fund and equipment, running cost, and processing cost is high, can pollute environment simultaneously.Therefore, the improvement of paper industry waste residue mud environmental pollution and resource reutilization have caused showing great attention to of the whole society and governments at all levels.Seek a kind of feasible treatment process, be necessary in fact.
Summary of the invention
The present invention is directed to the deficiency and the defective of existing waste sludge from paper mill method for sludge treatment, a kind of preparation method of biomass solid formed fuel is proposed, fully effectively utilize biomass and waste sludge from paper mill mud, obtain a kind of calorific value height, can partly effectively substitute the solid molding fuel of coal, oil and Sweet natural gas.
In order to realize the foregoing invention purpose, the invention provides following technical scheme:
The preparation method of a kind of biomass solid formed fuel of the present invention in turn includes the following steps:
(1) in proportion water ratio 70-80% waste sludge from paper mill mud and biomass dry powder are sent into batcher, after mixing, get miscellany;
(2) step (1) gained miscellany is sent in the stirrer, fully stirred, break up miscellany, getting water ratio is the miscellany of 50-60%;
(3) with the miscellany of step (2) gained in conveyor delivery is gone into dryer;
(4) by dryer mixture moisture content is reduced to below 20%, and send in the branch feed bin by conveying belt;
(5) will divide by transfer roller that water ratio is at the mixture molding machine below 20% in the feed bin, compression moulding gets solid molding fuel, and solid molding fuel is through screening, cooling, air-dry, and water ratio further is reduced to about 12-15%;
(6) solid molding fuel of step (5) gained is sent into mechanical packer, get finished product.
Wherein, the mass ratio of water ratio 70-80% waste sludge from paper mill mud and biomass dry powder is 3-5: 5-7 described in the step (1).
Further, the mass ratio of water ratio 70-80% waste sludge from paper mill mud and biomass dry powder is 4: 6 described in the step (1).
Wherein, the churning time that stirs described in the step (2) is 5-8 minute.
Wherein, stirrer described in the step (2) is two rod formula stirrers.
Wherein, dryer is a rotating drum type drying machine described in the step (3).
Wherein, transfer roller described in the step (3) is for mixing the formula transfer roller.
The objective of the invention is waste sludge from paper mill mud and biomass dry powder are organically combined, make full use of waste sludge from paper mill mud and biomass dry powder and carried out the comprehensive utilization of resource utilization, not only make waste sludge from paper mill mud, biomass dry powder has obtained processing, biomass solid formed fuel that can also a kind of cleaning of successful output, can effectively replace fire coal, fuel oil, combustion gas in boiler, to use, help reducing the consumption of the mineral substance energy.
The waste sludge from paper mill mud that the present invention uses biomass dry powder and water ratio to reach about 70-80% mixes, and by both thorough mixing and breaing up, the moisture in the waste sludge from paper mill mud can be transferred in the biomass dry powder, and it is even finally to reach moisture.The profile that biomass dry powder is fluffy and the structure utmost point are beneficial to the rapid evaporation of moisture, both can make the mixture water content be reduced to 50-60% after mixing, mixture dewatering speed in dryer is faster than simple waste sludge from paper mill sludge dewatering speed, and drying temperature is also low, so consumption of calorie is less.Heat drying is 20-25% to the mixture water ratio, goes out to be cooled to water ratio behind the dryer and can to arrive about 20%.The mixture of this moment just in time is fit to the needs of briquetting or granulation, through high temperature extruding forming.Solid molding fuel is through screening, cooling, air-dry, and water ratio further is reduced to about 12-15%.
Above-mentioned biomass dry powder is the food bacterium slag after stalk, wood shavings, sawmilling, forest branches and leaves, the dregs of a decoction or the use.
